What Is Section 105 Under the Proposed Income Tax Bill 2025?
Section 105 of the proposed Income Tax Bill 2025 deals with unexplained expenditure under income tax. Under this proposed framework, a tax authority may treat certain spending as taxable income if you cannot satisfactorily explain the source of those funds.
Put simply: if your spending appears higher than your known or declared income sources, the Assessing Officer may ask you to prove where the money came from.
What Common Spending Can Attract Scrutiny?
Common situations that may attract attention under Section 105 unexplained expenditure income tax scrutiny include:
- Luxury domestic or international travel paid in cash or cards without clear income backing
- Expensive weddings, events, or functions — especially high-cash spending
- High-value business purchases without documented fund sources
- Large or repeated cash transactions above ₹2 lakh
- Spending patterns significantly inconsistent with declared income
- High-value property purchases, vehicle purchases, or jewellery
- Foreign remittances not backed by disclosed income
Key Provisions and Scope of Scrutiny Under Section 105
The proposed scope of Section 105 income tax bill broadly covers any expenditure incurred by a taxpayer during a financial year. If you cannot demonstrate how a purchase was funded, that amount may be treated as income and taxed accordingly.
Who May Be Covered?
| Taxpayer Category | Common Risk Situations | Risk Level |
|---|---|---|
| Salaried Individuals | High-value purchases exceeding net salary savings | Medium |
| Freelancers & Consultants | Lifestyle spend not matching declared freelance income | High |
| Small Business Owners | Cash purchases, undocumented inventory spends | Very High |
| MSMEs | Business expenses without proper books of accounts | High |

Section 69C vs Section 105 — What Is Different Under the Proposed Framework?
If you are familiar with the existing Income-tax Act, 1961, you may already know Section 69C. The proposed Income Tax Bill 2025 is expected to reorganise and streamline provisions, with Section 105 expected to correspond to existing Section 69C provisions on unexplained expenditure.
| Aspect | Section 69C (Existing Law) | Proposed Section 105 (Income Tax Bill 2025) |
|---|---|---|
| Legal Status | Existing, enforceable law | Proposed framework (bill stage) |
| Core Subject | Unexplained expenditure | Unexplained expenditure (same principle) |
| Legislative Language | Older, complex drafting | Expected to be modern, streamlined language |
| Compliance Environment | Traditional reporting and manual scrutiny | Greater use of digital reporting, AI, and data analytics |
| Detection Speed | Relatively slower case-by-case review | Faster automated detection and flagging |
| Practical Impact | Scrutiny based on facts and evidence submitted | Likely faster notices; documentation more critical than ever |
| Taxpayer Burden | Explain source of expenditure | Same burden; digital records will carry more weight |
Understanding Sections 69, 69A, 69B & 69C — Unexplained Amounts at a Glance
The existing Income-tax Act, 1961 has a family of provisions — Sections 69, 69A, 69B, and 69C — each dealing with a different type of unexplained amount. Understanding the distinction between unexplained investment vs unexplained expenditure is essential for correct compliance.
| Section | Subject | Simple Meaning | Common Example |
|---|---|---|---|
| Section 69 | Unexplained Investments | Investment not recorded in books or not satisfactorily explained | Property purchase not matching declared income or books |
| Section 69A | Unexplained Money or Valuables | Cash, bullion, jewellery, or valuables found in possession, unexplained | Cash discovered in search; jewellery without purchase proof |
| Section 69B | Understated Investment/Asset Value | Asset appears to cost more than what is recorded; excess is unexplained | Property stamp duty value much higher than declared purchase price |
| Section 69C | Unexplained Expenditure | Spending where the source of funds is not satisfactorily explained | Luxury holiday costing ₹10L while income declared is ₹5L |
| Proposed Section 105 | Unexplained Expenditure (Proposed) | Same as 69C but under modernised, streamlined Income Tax Bill 2025 language | Same situations as Section 69C, detected via digital analytics |

Priya responded with: a bank-sanctioned personal loan of ₹5 lakhs along with mutual fund redemption records of ₹3 lakhs.
Result: Because Priya could prove the source of expenditure with complete documentation, the AO accepted her explanation. No unexplained expenditure was added to her income. This is why proactive documentation saves lakhs in unnecessary tax.
Penalties for Unexplained Expenditure — What You Could Lose
The penalties under Section 105 unexplained expenditure (and existing Section 69C) are designed to be punitive. Understanding these before it happens is far better than learning them from a tax demand notice.

| Surcharge | 25% on the tax amount computed at 60% | Additional 15% of the expenditure |
| Health & Education Cess | 4% on (tax + surcharge) | Additional ~3% of the expenditure |
| Effective Total Tax Rate | Combined impact of all above | ~78% of unexplained amount |
| Penalty (Section 271AAC) | 10% of the tax payable on unexplained amount | Additional 6–8% of expenditure |
| Concealment Penalty (Section 270A) | 50%–200% of tax evaded if misreporting found | Could be higher than the original tax |
| Prosecution Risk | In severe / repeated cases | Criminal proceedings possible |

5 Steps to Avoid an Unexplained Expenditure Notice

Common Mistakes Taxpayers Make — And How to Avoid Them
Many taxpayers assume that a genuine expense will automatically be accepted. In practice, the lack of proof is the real issue — not whether the expense actually happened.
| Common Mistake | Why It Creates a Problem | How to Fix It |
|---|---|---|
| Heavy reliance on cash transactions | No banking trail; cannot prove source of funds | Use digital/cheque payments for all amounts above ₹10,000 |
| Not keeping receipts or invoices | Cannot prove the nature or genuineness of expense | Maintain digital copies of all invoices immediately |
| Undocumented loans from relatives | Treated as unexplained income/expenditure without documentation | Always get a written loan agreement; transact through bank |
| Accepting gifts without gift deeds | Donor's capacity and intent cannot be verified | Execute a proper gift deed with donor PAN |
| Ignoring income-spending drift over years | Cumulative mismatch becomes significant over time | Do an annual reconciliation of income vs spending |
| Ignoring or delaying notice response | Ex-parte assessment almost always goes against the taxpayer | Respond within the deadline; consult CA Sagar Batra immediately |
| Assuming one document alone is enough | Assessing Officers need a complete, consistent money trail | Build a file with multiple corroborating documents |
