Section 85 Exemption: The Complete Guide to Saving Long-Term Capital Gain Tax on Property Sale in India
Sold land or a building and worried about LTCG tax? Section 85 of the Income Tax Act, 2025 lets you invest up to ₹50 lakh in NHAI/REC bonds and legally eliminate or reduce your long-term capital gains tax — if you act within 6 months of sale.
What is Section 85? — Long-Term Capital Gain Tax Exemption on Property Sale
When you sell a property — land, a building, or both — after holding it for more than 24 months, the profit you make is called a Long-Term Capital Gain (LTCG). This gain is taxable under the Income Tax Act, 2025, and can result in a significant tax bill, especially in today's real estate market.
Section 85 of the Income Tax Act, 2025 provides a powerful and legal way to save or defer this long-term capital gain tax on property. By reinvesting your capital gains into specific government-approved bonds — issued by NHAI or REC — within 6 months of selling your property, you can claim a partial or full exemption from LTCG tax.
This provision is commonly referred to as the "capital gains bond exemption" or "54EC bond exemption" (under the older Income Tax Act, 1961). It is one of the most straightforward and cost-effective tax-saving tools available to property sellers in India.
💡 Why Section 85 Exists
The Government of India uses Section 85 to channel private capital into critical national infrastructure — highways (NHAI) and rural electrification (REC). In return, property sellers who invest their gains in these projects get to legally reduce or eliminate their LTCG tax burden. It is a win-win policy.

Who Can Claim Section 85 Long-Term Capital Gain Tax Exemption?
The benefit of Section 85 LTCG exemption is available to any assessee under Indian income tax law. This means:
⚠ The key requirement is not who you are, but the nature of your income. You must have a long-term capital gain specifically from the transfer (sale) of land, a building, or both. Without this qualifying gain, Section 85 does not apply.
What Qualifies as the "Original Asset" Under Section 85?
Under Section 85, the "Original Asset" means land, a building, or both land and building together. There are two strict conditions:
| Asset Type | Held >24 Months? | LTCG? | Section 85 Applies? |
|---|---|---|---|
| Land (plot, agricultural, commercial) | Yes | Yes | ✓ Yes |
| Residential building / flat / apartment | Yes | Yes | ✓ Yes |
| Commercial building / office / shop | Yes | Yes | ✓ Yes |
| Land or building held ≤24 months | No | STCG | ✗ No |
| Listed equity shares | Yes | Yes | ✗ No |
| Mutual funds (equity/debt) | Yes | Yes | ✗ No |
| Gold / jewellery / bonds | Yes | Yes | ✗ No |
What Are the NHAI/REC Bonds — The "New Asset" Under Section 85?
To claim the Section 85 long-term capital gain tax exemption on property, you must invest your gains in what the law calls a "Long-Term Specified Asset" — commonly known as Capital Gains Bonds or 54EC Bonds.
All three of the following conditions must be satisfied for the bonds to qualify:
| Condition | Requirement | Details |
|---|---|---|
| Issue Date | On or after 1 April 2018 | Only bonds issued after this date qualify. Older tranches do not. |
| Lock-in Period | Redeemable only after 5 years | Mandatory 5-year lock-in. Cannot be sold, transferred, or pledged before maturity without losing the exemption. |
| Issuer — NHAI | National Highways Authority of India | Funds India's highway infrastructure projects. AAA rated. Government-backed. |
| Issuer — REC | Rural Electrification Corporation Ltd. | Funds rural power and electrification projects. Government company. AAA rated. |
| Other Issuers | Central Govt. Notified Bonds | Government may notify other entities from time to time. Check the latest notifications before investing. |
NHAI and REC bonds are issued in limited tranches. They may not always be available for immediate subscription. Check with your authorised bank or broker well in advance of your 6-month deadline. Missing the window means your entire long-term capital gain becomes taxable.
The Critical 6-Month Investment Rule for Section 85 Exemption
This is arguably the most important rule in Section 85, and one that many property sellers miss. To claim the long-term capital gain tax exemption, you must invest in NHAI/REC bonds within 6 months from the date of transfer of your property.
Under Section 85, the date of transfer is the date on which the sale deed is registered at the Sub-Registrar's office. It is NOT:
• The date you signed an agreement to sell
• The date you received the advance payment
• The date of receiving the final sale amount
Anil sells his apartment and the sale deed is registered on 5th August 2025. His 6-month investment window to buy NHAI/REC bonds runs from 5th August 2025 to 4th February 2026. Any investment made after this date will NOT qualify for the Section 85 LTCG exemption.
Rina sold her land on 10 November 2025 (registered sale deed date). Even if she receives some instalment payments in 2026, her deadline is 9 May 2026. Plan early!
The ₹50 Lakh Investment Cap — All Scenarios Explained
Section 85 strictly limits the maximum investment eligible for long-term capital gain tax exemption to ₹50 lakh in total.
This cap applies across:
• All properties sold in a single tax year
• The combined total across the year of sale AND the following financial year (if your 6-month window spans two years)
Ramesh sells two plots in June 2025 and earns ₹90 lakh total LTCG. He can invest a combined maximum of only ₹50 lakh in NHAI/REC bonds — not ₹50 lakh per property. The remaining ₹40 lakh gain is taxable.
Geeta sells land in January 2026. Her 6-month window ends July 2026. She invests ₹20 lakh in Feb 2026 (FY 2025-26) and ₹30 lakh in May 2026 (FY 2026-27). Total = ₹50 lakh — allowed. She cannot claim a fresh ₹50 lakh limit in the new FY.

Section 85 vs Section 54 vs Section 54F — Which Saves You More Long-Term Capital Gain Tax on Property?
| Feature | Section 85 (LTCG Bond Exemption) | Section 54 (Buy Residential House) | Section 54F (Any Asset → House) |
|---|---|---|---|
| Original Asset | Land or Building (held >24 months) | Residential House Property only | Any long-term capital asset (not house) |
| New Investment Required | NHAI/REC or notified bonds | 1 residential house (India) | 1 residential house (India) |
| Investment Cap | ₹50 lakh (max) | Full capital gain (no cap) | Full net sale consideration |
| Investment Timeline | 6 months from sale date | 2 years (purchase) / 3 years (construction) | 2 years (purchase) / 3 years (construction) |
| Lock-in Period | 5 years (bonds) | 3 years (new house) | 3 years (new house) |
| Complexity | Simple — just buy bonds | High — property search, registration, etc. | High — house purchase required |
| Can Be Combined? | Yes — with Section 54 for larger gains | Yes — with Section 85 | Yes — check eligibility |
| Tax on Interest Earned | Taxable each year | Rental income taxable | Rental income taxable |
| Best Suited For | Quick, simple savings up to ₹50L | Those wanting to reinvest in property | Non-property assets, any long-term gain |
If your long-term capital gain from property sale exceeds ₹50 lakh, you can combine Section 85 and Section 54. Invest ₹50 lakh in NHAI/REC bonds (Section 85) and use the remaining gain to purchase a new residential house (Section 54). This dual strategy can maximise your total LTCG tax savings legally.
What Happens If You Sell, Transfer, or Pledge Bonds Before 5 Years?
Section 85 is very clear: holding the bonds for 5 years is a strict legal condition to retain the LTCG tax exemption. If you break the lock-in, the consequences are severe and automatic.
| Triggering Action | Tax Consequence | When Taxable? |
|---|---|---|
| Sell or transfer bonds before 5 years | Previously exempted LTCG becomes taxable | In the year of sale/transfer |
| Take loan against bonds as security (pledge) | Treated as "conversion to money" — LTCG revived | In the year loan is taken |
| Convert bonds to any other form before 5 years | Exemption fully withdrawn | In the year of conversion |
| Hold bonds for full 5 years and redeem at maturity | No tax on principal — exemption stands permanently | N/A — fully exempt |
Suresh invests ₹35 lakh in REC bonds in 2025, claiming full LTCG exemption. In 2028, he pledges these bonds to take a bank loan. Result: The law treats this as conversion to money. The full ₹35 lakh becomes taxable as long-term capital gain in FY 2028-29. Taking a loan against your Section 85 bonds is the same as selling them in the eyes of the law.
Step-by-Step Process to Claim Section 85 LTCG Exemption on Property
Calculate Your Long-Term Capital Gain (LTCG) Accurately
Use the formula: LTCG = Sale Price − Indexed Cost of Acquisition − Transfer Expenses. Apply the Cost Inflation Index (CII) notified by the government for the relevant years. Get this right — errors here affect the exemption amount.
Note the Exact Date of the Registered Sale Deed
Your 6-month clock starts from this date. The agreement to sell, possession date, or payment date are all irrelevant for this purpose.
Identify Eligible NHAI/REC Bond Tranches Currently Open
Contact your bank, financial advisor, or check NHAI/REC's official website for currently open bond tranches. Bond availability is periodic — act quickly.
Invest Within 6 Months — Keep a Clear Money Trail
Invest from the same bank account that received the sale proceeds. This creates a clear audit trail linking your sale proceeds to the bond investment — crucial in case of income tax scrutiny.
Ensure Total Investment Does Not Exceed ₹50 Lakh
Remember — ₹50 lakh is the combined cap across all properties sold, across both financial years if your window overlaps. Don't over-invest expecting additional exemption.
Collect and Preserve the Bond Certificate / Allotment Letter
This is your primary evidence for the Section 85 exemption claim. Keep it safely with your registered sale deed and capital gains computation.
File Your ITR Correctly — Declare Both Gain and Exemption
Report the full capital gain in your Income Tax Return (ITR-2) and claim the Section 85 exemption for the amount invested in bonds. Filing errors can result in the exemption being denied. Consider using CA Sagar Batra's expert ITR filing service at just ₹1,100.
Hold Bonds for 5 Years — Do Not Sell or Pledge
Mark your calendar for the 5-year maturity date. Do not sell, gift, or take any loan against these bonds. After 5 years, redeem freely — no tax on the principal.
Common Mistakes That Cost You the Section 85 LTCG Tax Exemption
| # | Common Mistake | Consequence | How to Avoid |
|---|---|---|---|
| 1 | Investing after the 6-month window | Full LTCG becomes taxable | Start planning from the date of sale deed registration. Don't wait. |
| 2 | Expecting ₹50L exemption per property sold | Over-investment, excess not exempt | Remember: ₹50L is the total cap across ALL properties for the relevant period. |
| 3 | Investing in spouse's or children's name | Exemption denied on assessment | The investment must be in the name of the property seller / assessee only. |
| 4 | Pledging bonds for a loan within 5 years | Exemption reversed, tax payable immediately | Never use Section 85 bonds as security. Maintain liquidity separately. |
| 5 | Not reporting gain + exemption in ITR | Notice from Income Tax department | Always disclose full LTCG and the Section 85 exemption in your ITR. |
| 6 | Counting agreement date as transfer date | Wrong 6-month deadline, potential miss | Always use the registered sale deed date for calculating the 6-month window. |
| 7 | Investing in unqualified bonds | Exemption rejected | Only NHAI, REC, or Central Government-notified bonds qualify. Verify before investing. |

Frequently Asked Questions — Section 85 Long-Term Capital Gain Tax on Property
Example: Raju sells two plots with total LTCG of ₹80 lakh — maximum Section 85 exemption is ₹50 lakh, not ₹1 crore.
Always confirm eligibility under each section with your CA before proceeding.
If your sale deed is registered on 10 November 2025, your investment deadline is 9 May 2026, even if the full payment arrives in March 2026.
Only the original capital gain principal invested is exempt — the interest earned is not.
NRIs should also consider DTAA provisions and TDS implications — consult CA Sagar Batra for NRI-specific guidance.
Plan well in advance, monitor NHAI and REC's official websites, and check with authorised banks (like SBI, Bank of Baroda, etc.) early.
If bonds are genuinely unavailable throughout your window, the exemption cannot be claimed — there is no extension granted in the law for this reason.
The indexed cost of acquisition in such cases is computed differently (typically using the FMV on the date of inheritance). Always get this calculated by a CA to ensure accuracy.
You will only pay tax on the interest income earned during the holding period, which should have been reported each year in your ITR.
