Income Tax AIS Mismatch: What It Means and How to Handle It

If you have received an email, SMS or portal communication referring to an Income Tax AIS mismatch, do not immediately assume that additional tax, a penalty or a scrutiny proceeding has already been imposed. The first step is to identify exactly what communication you received, which transaction or income item is being referred to, and whether any action or response is actually required.

In simple terms, an AIS mismatch can arise when financial information available with the Income Tax Department does not appear to align with the income, transaction value, tax credit or tax treatment reflected in your filed ITR. The difference may relate to interest income, salary, dividends, shares, mutual funds, property transactions, bank deposits, TDS/TCS, specified financial transactions, foreign remittances or another item reported by a third party.

A mismatch does not automatically mean that your ITR is wrong. Sometimes the information reported by a bank, employer, deductor, broker or another reporting entity may relate to a different period, may contain a duplicate entry, may reflect gross transaction value rather than taxable income, or may require a different tax classification. That is why the underlying transaction should be verified before any correction is made.

If the mismatch has resulted in a formal information request from the Income Tax Department, our detailed guide on a Section 133(6) notice for AIS mismatch explains how to understand the queries, identify the supporting documents required and prepare an evidence-backed response through the applicable e-Filing process.

You should also compare the transaction with your AIS, TIS, Form 26AS, filed ITR and original source records. These records serve different purposes and should not be assumed to contain identical figures. For example, AIS may display transaction-level information, TIS may contain processed or derived information, and Form 26AS primarily reflects specified tax-related information such as TDS/TCS and certain other entries.

The correct response therefore depends on what caused the difference. In some cases the information may already have been correctly reported in the ITR and only needs to be reconciled. In another case, feedback may need to be submitted against an AIS entry. If income was genuinely omitted or incorrectly reported, the appropriate return correction or other compliance action may need to be examined separately.

This guide will help you understand the mismatch step by step—starting with how AIS information is collected, followed by the most common reasons for differences, methods to verify individual entries, documents that should be checked and the options available when the Department asks you to explain the discrepancy.

AIS is an important reconciliation source, but it is not your final tax computation. It reflects information presently available with the Income Tax Department from different reporting sources. Your final tax return must still be prepared using complete and accurate information from your actual financial records, even where a transaction is missing from AIS or appears there differently.

AIS Explained

What Is an Income Tax AIS Mismatch?

An Income Tax AIS mismatch generally means that information appearing in your Annual Information Statement does not appear to align with the income, transaction value, tax credit or treatment reflected in your Income Tax Return or underlying financial records.

The mismatch can arise because the Income Tax Department receives financial information from different reporting sources. AIS can include TDS/TCS information, Statement of Financial Transaction (SFT) data, tax payments and other information received by the Department. It therefore provides a broader transaction-level view that can be compared with your return and source records.

However, a difference between AIS and your ITR does not automatically mean that income was concealed or that additional tax is payable. The figures may differ because of timing, duplicate reporting, incorrect source information, gross-versus-net reporting, joint ownership, transaction classification or another legitimate reason that needs to be reconciled.

Simple way to understand it: AIS shows information available with the Income Tax Department from various sources. Your ITR contains the income and other particulars you reported for tax purposes. If the two appear inconsistent, you should first identify the underlying transaction and determine why the figures differ.

Where Does AIS Information Come From?

01 Banks & Financial Institutions

Interest, specified transactions and other reportable financial information.

02 Employers & Deductors

Salary-related information and TDS/TCS data reported through applicable statements.

03 Brokers & Investment Platforms

Information relating to securities and other reportable investment transactions.

04 Mutual Funds & Other Reporting Entities

Prescribed financial transactions reported under applicable information-reporting requirements.

05 Property-Related Reporting

Specified immovable-property transaction information reported under applicable provisions.

06 Other Department Information

Other information available to the Department, including specified tax and financial transaction data.

Does Every AIS Mismatch Result in an Income Tax Notice?

No. A difference you identify while reviewing AIS is not automatically a statutory notice, and not every mismatch necessarily results in a Department communication.

Depending on the circumstances, the Department may use different compliance mechanisms such as an e-Campaign, e-Verification, e-Proceedings or another applicable communication. The action required depends on the actual communication displayed in your account—not simply on the existence of an AIS difference.

Email communication
SMS notification
Portal / Compliance action
Do not treat an email or SMS by itself as proof that a statutory notice has been issued. Check your official e-Filing / Compliance Portal account, identify the type of communication and read the actual action requested. Different communications have different response procedures and deadlines.
Key Point

An AIS mismatch is a signal to reconcile the information—not an automatic finding that your tax return is wrong. Check the reported source, amount, financial year and tax treatment before deciding whether AIS feedback, an ITR correction or a response to a Department communication is actually required.

Know the Difference

Is It a Notice or Just a Compliance Alert?

An email or SMS mentioning an AIS difference does not, by itself, tell you whether you have received a general compliance communication, an e-Campaign, an e-Verification request or a formal statutory notice. The message may simply be notifying you that an item is available for review on the Income Tax portal.

That distinction matters because different Income Tax communications have different purposes, response procedures and consequences. You should therefore avoid treating every AIS-related message as either “nothing serious” or as a full scrutiny notice.

Compliance Communication

Review or Clarification May Be Requested

The Compliance Portal can contain items such as e-Campaigns and e-Verification matters that ask a taxpayer to review information or provide a response.

  • May relate to reported financial information
  • May ask you to confirm or explain a transaction
  • Can be visible through the Compliance Portal
  • Does not automatically mean an assessment has started
Statutory Notice / Proceeding

Action Is Required Under a Specific Provision

A formal notice or proceeding normally identifies the relevant statutory provision, the information or action required and the applicable response instructions or deadline.

  • Carries a specific legal basis or proceeding
  • Can require documents, explanations or another statutory response
  • May be available through e-Proceedings
  • Must be handled according to the actual notice
Email and SMS are communication channels—not the legal classification of the proceeding. A message on your phone may simply alert you to an item available on the portal. Log in independently to the official e-Filing / Compliance Portal and check what has actually been issued instead of deciding the nature of the communication from the SMS or email subject line alone.

Check These 4 Things Before You Respond

01 Communication Type

e-Campaign, e-Verification, e-Proceeding, intimation or notice.

02 Section / Reference

Check the section number, DIN or other document reference shown.

03 Action Required

Identify whether you need to confirm, explain, upload documents or take another action.

04 Response Deadline

Follow the date or submission window shown in the actual communication.

An unanswered compliance communication does not automatically “convert” into scrutiny or reassessment. If the Department later considers another statutory proceeding appropriate, that proceeding must operate under its own legal framework and conditions. The safest approach is still to review any active compliance item promptly and respond accurately where a response is required.
Simple Rule

Do not judge the seriousness of an AIS communication by whether it arrived through SMS or email. Open the official portal, identify the exact compliance item or proceeding, check what is being asked and then respond according to that specific communication.

Scam Protection

How to Tell a Genuine Income Tax Message From a Scam

Fake tax emails, SMS messages and websites do exist, so you should verify an Income Tax communication before sharing information, opening attachments or taking action through a link contained in the message.

A professional-looking logo, sender name or SMS header is not enough by itself to prove authenticity. Fraudsters can imitate branding and create links that look similar to legitimate government websites.

The safest rule: do not rely only on the link contained in an unexpected tax email or SMS. Open the official Income Tax e-Filing portal independently and verify whether the communication, notice or compliance item actually exists.
Safer Indicators

What You Should Verify

These indicators can support authenticity, but the official portal remains the stronger verification source.

  • The communication corresponds with an item visible on the official Income Tax portal
  • A formal communication contains the relevant document details, section or reference information
  • A notice/order/letter can be authenticated using the Department's official verification service
  • The requested action matches what is displayed in your portal account
Warning Signs

Treat the Message With Caution

Be particularly careful where a message creates urgency and asks you to provide sensitive information through an unfamiliar channel.

  • It asks for your e-Filing password, banking PIN or card/account access credentials
  • It asks you to provide confidential banking information through email or a suspicious form
  • It pressures you to open an unexpected attachment or immediately click an unfamiliar link
  • The alleged notice cannot be matched with the official portal or authenticated using official Department tools
Received a Formal Notice, Order, Summons or Letter? Authenticate It on the Official Portal

The Income Tax Department provides a pre-login “Authenticate Notice / Order issued by ITD” service. You do not need to sign in to your e-Filing account merely to use this authentication facility.

Method 1 DIN + Mobile Number + OTP
Method 2 PAN + Document Type + Tax/Assessment Year + Date of Issue + Mobile Number + OTP

Safe Way to Check an Unexpected Tax Message

01 Do Not Rush

Do not immediately click the message link or open an unexpected attachment.

02 Open the Portal Yourself

Navigate independently to the official Income Tax e-Filing portal.

03 Check the Communication

Review Pending Actions, Compliance Portal or the relevant proceeding area.

04 Authenticate if Applicable

Use the official Notice / Order authentication service for formal ITD correspondence.

Never share your e-Filing password, banking PIN, card PIN or similar financial-account access information in response to an email or suspicious message. The Income Tax Department specifically warns taxpayers not to respond to phishing emails requesting confidential financial information and advises users not to click suspicious links or open unexpected attachments.
Best Verification Rule

Trust the official portal verification—not just the appearance of the message. If an email or SMS claims that you have an AIS issue, compliance action or tax notice, independently check the official portal and verify the actual communication before responding or sharing sensitive information.

Understand the Records

How AIS, TIS, Form 26AS and Your Filed ITR Connect

To understand an AIS mismatch correctly, you need to know that AIS, TIS, Form 26AS and your filed ITR are related—but they are not four copies of the same statement. Each one serves a different purpose and may therefore display information in a different way.

A difference should not automatically be treated as an error. The correct approach is to identify which source reported the transaction, understand what each record is showing and then reconcile that information with your actual bank statements, tax certificates, investment records and other supporting documents.

01 Detailed Information

AIS — Annual Information Statement

AIS provides a broader view of information available with the Income Tax Department. It can include TDS/TCS information, SFT information, tax payments, demand/refund information and other data received from different reporting sources.

Useful for: checking transaction-level information and identifying what has been reported against your PAN.
02 Aggregated Summary

TIS — Taxpayer Information Summary

TIS presents category-wise aggregated information from AIS. It can show the value processed by the system after applicable processing or deduplication and the value accepted by the taxpayer or confirmed by the source.

Useful for: understanding the processed category-level amount that may be used for return pre-filling where applicable.
03 Tax Credit Statement

Form 26AS — TDS/TCS Information

From Assessment Year 2023–24 onwards, Form 26AS available through TRACES displays TDS/TCS-related information. Broader information that was historically associated with Form 26AS is now available through AIS.

Useful for: checking tax deducted or collected against your PAN and reconciling the tax credit claimed in the return.
04 Taxpayer Filing

Your Filed Income Tax Return

Your ITR is the return actually filed by you, containing the income, deductions, gains, losses, tax credits and other particulars required for the applicable return form.

Useful for: checking how the underlying income or transaction was ultimately reported for tax purposes.

How These Four Records Work Together

01 Source Reports Data

A bank, employer, deductor, broker or other reporting entity submits applicable information.

02 AIS Displays Information

The relevant information available with the Department may appear in your AIS.

03 TIS Summarises It

TIS aggregates information into categories and shows processed and accepted/confirmed values.

04 ITR Reports Tax Position

Your return reflects the final income and tax treatment based on the applicable law and records.

Important Form 26AS update: do not rely on older articles that describe Form 26AS as the main place for property transactions, SFT information, advance tax, self-assessment tax, refunds and similar broader financial information. From AY 2023–24 onwards, the Department states that Form 26AS on TRACES displays only TDS/TCS-related data, while the broader information is available through AIS.
Simple Example

Suppose a bank reports interest information that appears in AIS and is aggregated under the relevant interest category in TIS. Form 26AS may separately show the corresponding TDS/TCS-related information where applicable, while your ITR shows how much interest income you actually reported for tax purposes. If those figures appear different, the next step is to reconcile the bank statement, interest certificate, AIS/TIS data, tax credit and filed return before deciding that anything is wrong.

A mismatch does not necessarily mean all four records must contain exactly the same number. One record may show a gross transaction value, another may show an aggregated or processed value, Form 26AS may show the related TDS/TCS information, and the ITR may contain the taxable amount determined under the applicable tax rules. Reconcile the underlying transaction rather than forcing every statement to match mechanically.
Key Takeaway

AIS tells you what information is available with the Department, TIS summarises and processes that information, Form 26AS helps verify TDS/TCS data, and your ITR shows what you actually reported for tax purposes. When a difference appears, compare all four with the original source records before deciding whether AIS feedback, tax-credit correction or an ITR-related action is required.

Common Causes

Common Reasons You May See an AIS Mismatch

AIS differences can arise for many reasons. Sometimes the taxpayer has missed income while filing the return; in other cases the source-reported information may be duplicated, incorrectly classified or simply different from the amount that is actually taxable.

The important step is to identify the underlying transaction before assuming either the AIS or the ITR is wrong. These are some of the most common situations worth checking.

01

Income Was Missed While Filing the ITR

A taxpayer may unintentionally leave out an income item that has been reported to the Department by another entity.

  • Savings or fixed-deposit interest
  • Dividend income
  • Capital gains from shares or mutual funds
  • Property-related income or gains
  • Professional, freelance or other receipts
Check the source statement and determine whether the amount was actually omitted before changing the return.
02

Wrong ITR Form or Missing Schedule

Selecting an unsuitable return form does not itself create an AIS mismatch, but it can prevent required income or disclosure schedules from being reported correctly.

  • Capital gains requiring an applicable return form
  • Business or professional income
  • Foreign assets or foreign-source income
  • Other disclosures unavailable in a simpler form
For example, ITR-1 and ITR-4 do not contain Schedules FA, FSI and TR for applicable foreign disclosures.
03

AIS Information Is Incorrect or Needs Context

AIS is based on information available with the Department from reporting sources. An entry may need correction or explanation instead of being copied mechanically into the return.

  • Duplicate reporting
  • Incorrect transaction value
  • Transaction belongs to another person
  • Joint transaction attributed differently
  • Gross amount differs from taxable income
AIS provides a feedback facility for active information where the reported entry requires correction or clarification.
04

TDS/TCS Credit Does Not Match the Related Income

A tax credit may appear against your PAN while the related income has been omitted, reported under a different head or recorded for a different amount.

  • FD interest with TDS but no matching interest entry
  • Professional receipt and TDS reported differently
  • Deductor used an incorrect amount
  • Timing difference between income and reporting
Reconcile the tax credit with the underlying income; do not add income merely to force a numerical match.
05

Foreign Assets or Foreign Income Need Review

For taxpayers to whom foreign reporting requirements apply, overseas accounts, investments, assets or foreign-source income can require specific ITR schedules.

  • Foreign bank or depository accounts
  • Overseas shares or investment interests
  • Foreign-source salary, interest or dividend
  • Foreign tax relief claims
Residential status matters. Schedule FA does not apply in the same way to every taxpayer.
06

Timing, Classification or Gross-Value Difference

Sometimes there is no missing income at all. The same transaction may simply appear differently across AIS, source records and the ITR.

  • Transaction reported in a different period
  • Gross sale value versus taxable gain
  • Reimbursement versus taxable receipt
  • Principal amount versus interest income
  • Accounting classification differences
Reconcile the nature of the amount, not just the headline number displayed in AIS.
AIS itself provides a feedback mechanism. The Income Tax Department allows feedback on active information displayed under TDS/TCS, SFT and Other Information. After feedback is submitted, AIS can show both the reported value and a modified value reflecting taxpayer feedback or source confirmation. That does not mean every difference should be marked incorrect—use the feedback option that matches the actual facts.
Foreign reporting needs special care. Current Income Tax Department guidance states that Schedule FA is for applicable residents and need not be completed by a taxpayer who is Not Ordinarily Resident (RNOR) or Non-Resident. Schedule FSI is also a resident-only schedule for income accruing or arising from sources outside India. Therefore, avoid the blanket statement that every taxpayer with a foreign account or overseas transaction must disclose it in the same manner.
Best Approach

Do not correct a mismatch until you know why the figures differ. Compare the AIS entry with the original bank, employer, broker, deductor or transaction record; identify the correct financial year and tax treatment; then decide whether the appropriate action is AIS feedback, a tax-credit correction, an ITR-related correction or simply keeping a reconciliation explaining the difference.

Non-Filing & AIS

Non-Filing Alerts and High-Value Transactions: When Is an ITR Actually Required?

Sometimes the Income Tax Department may have financial information against your PAN even though no Income Tax Return has been filed for the relevant period. That information can come from banks, deductors, financial institutions and other reporting entities.

But there is an important distinction: a transaction appearing in AIS or other Department data does not automatically mean that you were legally required to file an ITR. The filing obligation must be tested under the applicable return-filing provisions for that tax year.

Two different questions must be answered: first, why is the transaction appearing in the Department's information systems? Second, did your income, residential status or a specific statutory condition make return filing mandatory? These questions are related, but they are not the same.
Reported Transaction

A Transaction May Appear in AIS / Department Data

Specified entities report prescribed financial and tax information to the Department. As a result, a taxpayer can have significant financial activity visible to the Department even where no return has yet been filed.

  • Bank deposits or financial transactions
  • Securities or investment-related information
  • Property-related reported transactions
  • TDS/TCS information against the PAN
  • Other prescribed SFT or reporting data
Filing Requirement

ITR Filing Depends on Specific Legal Conditions

Filing can be mandatory because income exceeds the applicable limit or because another statutory condition applies even where ordinary taxable income would otherwise be below that limit.

  • Income-based filing requirement
  • Applicable foreign-asset filing requirement
  • Prescribed high-value transaction conditions
  • Business or professional receipt conditions
  • TDS/TCS-based filing conditions

Current Prescribed Filing Conditions for Tax Year 2026–27

01 Current Account Deposits

Aggregate deposits exceeding ₹1 crore in one or more current accounts.

02 Foreign Travel Expenditure

Aggregate expenditure exceeding ₹2 lakh on specified foreign travel for self or another person.

03 Electricity Expenditure

Aggregate expenditure exceeding ₹1 lakh towards electricity consumption.

04 Business Turnover / Receipts

Total business sales, turnover or gross receipts exceeding ₹60 lakh.

05 Professional Receipts

Total gross professional receipts exceeding ₹10 lakh.

06 TDS + TCS

Aggregate TDS and TCS of ₹25,000 or more; for a resident individual aged 60 or more, the prescribed amount is ₹50,000 or more.

07 Savings Account Deposits

Aggregate deposits of ₹50 lakh or more in one or more savings bank accounts.

08 Other Mandatory-Filing Conditions

Filing may also be required because of income, applicable foreign assets or another condition under the Act, independent of the transaction thresholds above.

Buying a car, purchasing property or making a large credit-card payment should not automatically be described as an ITR-filing trigger. Such transactions may be reportable or may appear in Department information depending on the applicable reporting rules, but the current prescribed mandatory-filing conditions must be checked separately. The existence of a high-value transaction alone does not establish that tax is payable either.

What Should You Do If You Receive a Non-Filing Communication?

01 Verify the Communication

Open the official portal independently and identify the actual compliance item.

02 Check the Transaction

Confirm whether the reported transaction belongs to you and whether the amount is correct.

03 Test Filing Obligation

Check income, transaction thresholds and other mandatory-filing conditions for the relevant year.

04 Take the Correct Action

File or update the return where legally available and required, or respond to the compliance item based on the actual facts.

2026 law transition: for tax year beginning 1 April 2026, return filing is governed by Section 263 of the Income-tax Act, 2025. Rule 163 of the Income-tax Rules, 2026 prescribes the transaction and receipt conditions listed above. Earlier assessment years can continue to be governed by the corresponding provisions of the Income-tax Act, 1961.
Key Takeaway

High financial activity can prompt the Department to ask why no return was filed, but “high-value transaction” and “mandatory ITR filing” are not interchangeable terms. Verify the transaction first, then test your filing obligation against the income and statutory conditions applicable to that tax year before deciding what response or return-filing action is required.

Don't Leave It Unchecked

What Happens If You Ignore an AIS Mismatch?

An AIS difference does not automatically create a tax demand or penalty. However, if the Department has created an active compliance item, e-Verification request or another proceeding, leaving it unanswered can mean the underlying discrepancy remains unresolved.

What happens next depends on the actual transaction, whether income was correctly reported and whether the legal conditions for any further tax proceeding are independently satisfied.

AIS mismatch ≠ automatic tax liability. A difference in reported information is the starting point for reconciliation. Tax, interest, penalty, reassessment or any other statutory consequence requires its own factual and legal basis.
01

The Compliance Issue May Remain Open

If an active e-Campaign, e-Verification or other compliance item asks for your response and you do not address it, the Department may continue to have an unresolved difference on record.

Best approach: first identify whether the portal actually requires a response and what deadline applies.
02

Further Verification May Be Sought

Where the information remains material or unexplained, the Department may seek additional information through the compliance or proceeding mechanism applicable to the case.

Important: this is not the same as saying every unanswered AIS difference automatically becomes scrutiny.
03

A Separate Statutory Proceeding Could Arise

If information available with the Department indicates a separate issue—for example possible escaped income—the applicable assessment or reassessment provisions may become relevant.

Separate legal test: the Department must follow the statutory framework applicable to that proceeding.
04

Tax, Interest or Penalty May Arise Only From the Underlying Issue

If a later processing, assessment or other valid order determines that income was omitted or tax was underpaid, tax and the applicable interest or penalty provisions may then become relevant.

Key distinction: those amounts arise from the underlying tax default or order—not simply because AIS displayed a mismatch.
An Unresolved AIS Difference Does Not Automatically Mean:
  • An additional tax demand has already been created
  • Interest starts running merely because AIS figures differ
  • A penalty is automatically imposed
  • Scrutiny assessment automatically begins
  • Reassessment automatically starts
  • Your refund is automatically blocked
AIS mismatch and refund adjustment are separate issues. A mismatch by itself should not be described as automatically withholding or adjusting your refund. If there is an actual outstanding tax demand, the portal has a separate Response to Outstanding Demand process and applicable refund-adjustment procedure. Always identify the underlying demand or communication rather than assuming the AIS difference caused the refund issue.

What Should You Do Instead of Ignoring It?

01 Check the Portal

Confirm whether there is an active e-Campaign, e-Verification or proceeding.

02 Verify the Transaction

Compare AIS with the original bank, broker, employer or other source record.

03 Check Your Filed ITR

Determine whether the income or transaction was already reported correctly.

04 Take the Appropriate Action

Submit AIS feedback, respond to compliance or examine an ITR correction only where the facts require it.

Key Takeaway

Do not ignore an active AIS-related compliance item, but do not assume the worst either. Resolve the underlying transaction first. If the data is wrong, document why. If the return is correct, keep the reconciliation. If income was actually omitted, examine the legally available correction route. And if a formal notice is issued, respond according to that specific proceeding and deadline.

Step-by-Step Action Plan

How to Respond to an Income Tax AIS Mismatch, Step by Step

The correct response to an AIS mismatch depends on what the transaction represents, whether the source information is correct, how it was reported in your ITR and whether the Department has actually asked you to take action.

Use the following sequence before submitting AIS feedback, changing your tax return or responding to a compliance communication.

Use the official portal as the source of truth. An SMS or email may only alert you that something requires attention. Log in independently and identify the actual AIS entry, compliance item or proceeding before deciding what response is required.
01

Identify Exactly What Communication You Received

Read the complete email or portal communication, but do not assume that the email itself determines the legal nature of the issue. Check whether you are dealing with an AIS entry, e-Campaign, e-Verification request, e-Proceeding or another communication.

  • Note the financial or tax year
  • Identify the transaction or income category
  • Check the reported amount
  • Note any response deadline shown
Important: do not rely on the SMS alone when the official portal contains fuller details.
02

Log In to the Official Income Tax Portal

Open the official Income Tax e-Filing portal independently rather than using an unexpected link received by SMS or email. Then locate the relevant AIS or compliance item in your account.

Security: verify the communication first if anything about the sender, link or request appears suspicious.
03

Review AIS and TIS

From the e-Filing portal, go to the AIS area and examine the relevant transaction. AIS can currently be downloaded in PDF, JSON and CSV formats. Review the corresponding TIS category as well.

  • Identify who reported the transaction
  • Check the reported amount and year
  • Determine whether the transaction belongs to you
  • Understand whether AIS shows transaction value or an amount that is actually taxable
04

Reconcile AIS With the Original Source Records

Do not compare only headline figures. Reconcile the AIS/TIS entry with your bank statement, interest certificate, broker statement, property documents, employer record, invoices or other original evidence.

Also check the filed ITR and, where relevant, Form 26AS. Remember that from AY 2023–24 onwards Form 26AS on TRACES primarily displays TDS/TCS information rather than the broader financial data now available through AIS.

Goal: identify why the figures differ—not simply which statement has the larger number.
05

Choose the Action That Matches the Actual Problem

Once the reason for the mismatch is clear, choose the correction or response route that fits the facts.

AIS Data Is Incorrect Submit appropriate AIS feedback against the active information.
AIS Is Correct, ITR Is Correct Keep a clear reconciliation explaining why the displayed figures differ.
Income Was Omitted Examine whether a revised or updated return is legally available and appropriate.
Return Was Not Filed First determine whether filing was mandatory and which filing route remains legally available.
Compliance Response Required Respond through the portal workflow shown against the active compliance item.
Formal Notice Issued Follow that specific notice, its queries, supporting-document requirements and deadline.
06

Review the Tax Treatment Before Changing the ITR

AIS may show a gross transaction value or third-party reported amount that is not identical to taxable income. For example, the sale value of shares or property is not automatically the same as taxable capital gain.

  • Check gross amount versus taxable income
  • Check cost, deductions and exemptions where applicable
  • Check timing and ownership
  • Confirm that the amount belongs to the correct year
Review first: correct the return only when the return itself actually contains an omission or wrong statement.
Do not file a “blind revision” simply to match AIS. Increasing income merely because AIS displays a higher transaction value can produce an incorrect tax result. Equally, do not ignore genuinely omitted taxable income. Determine the correct tax treatment from the underlying transaction first, then use the appropriate compliance route.
Revised Return vs Updated Return — They Are Not the Same

A revised return is used to correct an omission or wrong statement in a return already filed, provided the applicable revised-return window remains open.

An updated return is a separate route available subject to statutory conditions. It may be used in specified cases to disclose additional or inaccurately reported income after the ordinary revision window, and can involve additional income-tax. It cannot simply be used whenever the taxpayer wants a more favourable refund or lower tax result.

Current 2026 position: for AY 2026–27 under the Income-tax Act, 1961 framework, the revised-return period has been extended up to the end of that Assessment Year, subject to the applicable provisions and fee after the specified stage. For Tax Year 2026–27 under the Income-tax Act, 2025, Section 263 contains the revised-return and updated-return framework. Always check which tax year and Act govern the return before choosing the correction route.
Best Response Sequence

Verify → Reconcile → Determine the tax treatment → Then respond or correct. AIS is a powerful information source, but a mismatch should not be resolved by mechanically copying the AIS figure into the ITR. Use the source documents and applicable tax rules to establish the correct amount first.

Extra Care Required

A Special Word on Foreign Assets and Overseas Income

Foreign-asset and foreign-income mismatches deserve additional attention because the reporting rules depend on factors such as residential status, type of asset, source of income, ownership and the applicable tax year.

Do not assume that every foreign transaction is taxable in India, but equally do not assume that no disclosure is required merely because tax was paid overseas or because the amount appears small.

Foreign Non-Disclosure Can Carry Separate Consequences

The Black Money Act contains separate penalty and prosecution provisions for specified failures relating to foreign assets and foreign-source income. Their application depends on the taxpayer's residential status, the nature and value of the asset, the relevant year and the precise default. If an AIS-related issue involves an overseas account, investment, property or foreign income, consider a professional review before making a correction or formal response.

Better Filing Habits

How to Reduce Avoidable AIS Mismatches

You cannot guarantee that AIS and your ITR will never show a difference, because AIS depends partly on information reported by third parties. But a few filing habits can reduce avoidable errors and make reconciliation much easier.

Review AIS & TIS Before Filing

Compare them with bank, broker, employer and other source records before finalising the return.

Report All Required Income

Include applicable interest, dividends, gains and other income even if an item is small.

Use the Correct ITR Form

Choose a return form that supports the income and disclosure schedules relevant to your case.

Reconcile TDS/TCS With Income

Check that tax-credit claims relate correctly to the income or transaction behind them.

Review Foreign Reporting

Complete applicable foreign-asset, foreign-income and tax-relief schedules where required.

File Within the Applicable Timeline

Timely filing generally preserves more ordinary correction options if an error is identified later.

How Easy Return Can Help With an AIS Mismatch

The Easy Return tax team can help you identify the source of a mismatch, reconcile the underlying records and determine which compliance route may be appropriate based on the facts.

Review Identify the Mismatch

Compare the reported AIS entry with the filed return and source records.

Reconcile AIS / TIS / ITR Analysis

Determine why the figures differ instead of mechanically forcing them to match.

Filing ITR Form & Schedule Review

Check whether the original return form and applicable schedules were appropriate.

Feedback AIS Feedback Assistance

Help identify the feedback option that matches the actual source-data issue.

Compliance Portal Response Review

Organise facts and records for an applicable e-Campaign, e-Verification or other response.

Foreign Foreign Income & Asset Review

Review applicable foreign reporting and tax treatment where the mismatch involves overseas transactions.

Review Process

How the Review Process Works

01 Share the Context

Provide the communication and relevant tax-year details.

02 Review Records

Compare AIS/TIS, ITR and relevant source documents.

03 Identify the Cause

Determine whether the issue is source data, classification, timing or return reporting.

04 Evaluate Tax Impact

Check whether the difference actually changes taxable income or tax credit.

05 Select the Appropriate Route

AIS feedback, portal response or return correction is considered based on the facts.

06 Preserve the Record

Keep copies of the reconciliation, submission and supporting evidence.

When Review May Help

When Should You Consider Professional Help?

The AIS amount is large or you cannot identify its source.
You received an active compliance or verification communication.
The issue involves property, shares, F&O or complex capital gains.
Foreign assets, overseas income or foreign tax relief are involved.
The ITR form or tax treatment used appears to be incorrect.
Several records or tax years need to be reconciled together.
Not every AIS mismatch requires professional help. A straightforward source-data error or clearly documented difference may be manageable yourself. Professional review becomes more useful when the tax treatment, records, correction route or potential consequence is uncertain.

Final Summary

Key Takeaways

An AIS difference is not automatically a penalty, demand or finding of undisclosed income.
Common causes include omitted income, incorrect source-reported data, timing differences, gross-value reporting and return-form or schedule issues.
AIS, TIS, Form 26AS and your ITR do not need to show identical headline figures; they need to be reconcilable to the underlying transaction.
An active compliance communication should be reviewed promptly, but it does not automatically mean scrutiny or reassessment has begun.
Do not revise an ITR only to make it numerically match AIS. First establish the correct taxable amount.
Foreign-asset and foreign-income issues require particular care because separate disclosure and Black Money Act provisions may apply.
Final Rule

Verify first, reconcile second, and correct only what is actually wrong. An AIS mismatch is best handled by identifying the source transaction, checking the tax treatment and then choosing the response or correction route that matches the facts—not by assuming either the AIS or the filed ITR must automatically be changed.

Frequently Asked Questions

Frequently Asked Questions About Income Tax AIS Mismatch

Clear answers to common questions about AIS differences, compliance communications, return correction, refunds, foreign reporting and when professional review may help.

1. Is an Income Tax AIS mismatch email or SMS genuine?

It may be genuine, but you should not decide authenticity from the sender name, logo or SMS header alone. Open the official Income Tax e-Filing portal independently and check whether the relevant AIS, compliance item or communication is actually available there.

Avoid entering passwords, banking credentials or OTPs through an unexpected link sent by email or SMS.
2. Is an AIS mismatch the same as a statutory Income Tax notice?

No. An AIS difference by itself is not a statutory notice. Depending on the facts, you may simply be reviewing an AIS entry, or there may be an e-Campaign, e-Verification request, e-Proceeding or another formal communication on the portal.

Identify the actual communication and legal provision before deciding what response is required.

3. Why did I get an AIS mismatch even though I filed my ITR?

Filing an ITR does not guarantee that every third-party reported amount will match it numerically. Differences can arise because of omitted income, timing, duplicate reporting, incorrect source data, gross-versus-taxable amounts, ownership differences or an unsuitable return form or schedule.

4. Why did I receive a non-filing communication even when my income may not be taxable?

The Department may have significant financial or tax information against your PAN even though no return was filed.

But high-value activity does not automatically mean that an ITR was mandatory. Your filing obligation has to be checked under the income limits and the specific mandatory-filing conditions applicable to that tax year.

5. What should I do first after receiving an AIS mismatch communication?

Log in independently to the official portal and identify exactly what has been issued. Then compare the relevant AIS/TIS information with your original source records and filed ITR.

Verify first → reconcile second → take corrective action only after you know why the figures differ.
6. Can I file a revised return after discovering an AIS mismatch?

A revised return may be available if you filed an eligible original or belated return, discovered an omission or wrong statement and the applicable revised-return deadline has not expired.

Under the Income-tax Act, 1961 framework, Section 139(5) generally permits revision before the statutory cut-off or completion of the assessment, whichever occurs earlier.

If the normal revision window has closed, an updated return may be a separate possibility in qualifying cases. It is not a substitute for every type of correction.
7. What if a transaction shown in AIS does not belong to me?

AIS provides a feedback facility for active information. Where the entry genuinely does not belong to you, select the feedback option that accurately reflects that fact and retain supporting evidence.

Do not claim identity theft or PAN misuse unless the facts actually support that conclusion.

8. Can AIS data itself be incorrect?

Yes. Source-reported information can occasionally contain duplication, incorrect values, classification issues or information that needs contextual explanation.

AIS therefore provides a taxpayer feedback mechanism instead of requiring you to accept every reported entry without verification.

9. What is the difference between AIS and TIS?

AIS provides detailed information available with the Department from different reporting sources. TIS presents category-wise aggregated information and can show the value processed by the system and the value accepted by the taxpayer or confirmed by the source.

TIS is therefore more than simply a shortened PDF version of AIS.

10. Can my refund be held or adjusted because of an AIS mismatch?

An AIS mismatch by itself does not automatically block or adjust a refund.

Refund set-off can arise where an actual amount remains payable under the tax law, subject to the applicable intimation process. Refund withholding can also arise in specified circumstances where an assessment or reassessment is pending.

If your refund is affected, check whether there is an actual outstanding demand or pending proceeding instead of assuming AIS caused the issue.
11. Is foreign income or foreign-asset disclosure always mandatory?

Not for every taxpayer in the same way. Residential status is critical.

Schedule FA is generally relevant for applicable residents with specified foreign assets or interests, while the Department's guidance states that it need not be filled by a Non-Resident or Resident but Not Ordinarily Resident (RNOR).

Foreign-source income and foreign-tax relief also have their own reporting requirements where applicable.

12. Can salaried taxpayers also have AIS mismatches?

Yes. Salary may be your main income, but AIS can also contain information relating to interest, dividends, securities, capital gains, TDS/TCS and other reported transactions.

Salaried status does not mean that the salary figures are the only information requiring reconciliation.

13. Will buying a car or property automatically trigger scrutiny?

No. A large purchase or reported transaction does not automatically place a return under scrutiny.

Certain transactions may be reported or otherwise become available to the Department under applicable information-reporting rules. If further enquiry is considered necessary, the Department must use the appropriate compliance or statutory process.

14. Should I revise my ITR immediately just to make it match AIS?

No. First determine whether the filed return is actually wrong.

AIS may display gross transaction value rather than taxable income. For example, sale consideration is not necessarily equal to taxable capital gain.

Correct the return only when the return itself contains an omission or wrong statement.
15. Can using the wrong ITR form cause problems?

Yes, if the form you selected is not applicable to your income profile or does not contain the schedules needed for required disclosures.

But it is too broad to say that every wrong-form case automatically invalidates the return, blocks a refund or causes scrutiny. The effect depends on the specific error and how it is addressed.

For example, current ITR-1 eligibility excludes taxpayers with business/professional income, specified foreign assets/income and several other situations. :chatgpt-content-reference{index="2"}

16. Are AIS mismatch alerts automatically sent every year?

No. AIS is an annual information statement, but there is no rule that every taxpayer with a difference must receive an “AIS mismatch alert” every year.

Compliance communications can depend on the information available with the Department, the issue identified and the compliance mechanism being used for that period.

17. Can I ignore AIS if my Form 26AS matches my ITR?

No. From AY 2023–24 onwards, Form 26AS available through TRACES displays TDS/TCS-related information, while broader information is available through AIS. :chatgpt-content-reference{index="3"}

Therefore, a matching Form 26AS does not prove that every AIS transaction has been reviewed or that the ITR is complete.

18. Do I need professional help for an AIS mismatch?

Not necessarily. A simple duplicate entry, straightforward interest difference or clearly documented transaction may be manageable yourself.

Professional review becomes more useful where the issue involves foreign assets, substantial unexplained amounts, complex capital gains, multiple tax years, non-filing, uncertain return-form eligibility or an active formal proceeding.

Professional assistance can improve the quality of the reconciliation or response, but it cannot guarantee a particular Department outcome.
Final Reminder

An AIS mismatch is a reconciliation issue first. Verify the source transaction, compare it with your ITR and supporting records, identify whether any portal action is actually pending and only then decide whether AIS feedback, return correction or a formal response is required.
