Tax
Section 54: Capital Gains Exemption on a Residential House
Sell a house, buy a house, pay no tax on the gain. That is genuinely the deal — and there is a deadline buried inside it that costs people the whole exemption every single year.
The short answer
Section 54 exempts the long term capital gain from selling a RESIDENTIAL HOUSE, if you reinvest it in another RESIDENTIAL HOUSE.
Buy within 1 year before or 2 years after the sale, or construct within 3 years. Capped at ₹10 crore.
And the trap: if you haven't reinvested by the time your tax return is due, you must park the money in a Capital Gains Account Scheme — or lose the exemption entirely.
What Section 54 does
You sell a residential house. You make a long term capital gain. You buy another residential house with it.
The gain is exempt — to the extent you reinvested it.
The logic is simple: you haven't really cashed out. You have moved house. The state does not wish to tax you for that.
How much is exempt
- Long term capital gain
- ₹60,00,000
- Reinvested in a new house
- ₹60,00,000
- Taxable gain
- ₹0
- If you only reinvested ₹40,00,000
- Exempt
- ₹40,00,000
- Taxable gain
- ₹20,00,000
This is the single biggest advantage Section 54 has over Section 54F, and it is worth understanding clearly.
Sell a house for ₹2 crore with a ₹60 lakh gain. Under Section 54, you need to reinvest ₹60 lakh to exempt it all.
Under Section 54F — which applies when you sell something that isn't a house — you would have to reinvest the entire ₹2 crore.
Same money. Very different test.
The conditions
| Condition | Detail |
|---|---|
| What you sold | A residential house property. Not land. Not a shop. Not shares. |
| Holding period | It must have been long term — held more than 24 months. |
| What you buy | A residential house in India. |
| Timing — purchase | 1 year before or 2 years after the date of sale. |
| Timing — construction | Within 3 years of the date of sale. |
| How much | The capital gain — not the whole sale price. |
| Cap | ₹10 crore. |
| Number of houses | One. (A once-in-a-lifetime option for two houses exists where the gain does not exceed ₹2 crore — ask your CA.) |
| Lock-in | Do not sell the new house for 3 years, or the exemption is reversed. |
The deadline that catches people every year
You have 2 years to buy, or 3 years to construct. Generous.
But your income tax return is due long before that — typically 31 July of the following year.
If you have not reinvested by the ITR due date, you must deposit the unutilised gain into a Capital Gains Account Scheme (CGAS) account with a bank.
Miss it, and the exemption is gone. Even if you buy the perfect house, entirely within the 2-year window, a year later.
The gain becomes taxable in the year of sale. The house you eventually bought does not help you. It is a purely administrative failure — and it happens constantly.
Open the CGAS account. It costs nothing. Withdraw from it when you buy. If you never use it, the money becomes taxable after three years — which is a manageable outcome. Losing an exemption for want of a bank account is not.
The 1-year-before rule — badly underused
Up to one year before, and still claim the exemption.
Which is how most people actually move: you find the new place, you buy it, and then you sell the old one.
People assume the purchase must follow the sale. It needn't.
If you bought a house in the last 12 months and are now selling your old one — you may well qualify, and not know it. Ask your CA before you file.
The 3-year lock-in
Sell the new house within 3 years and the exemption you claimed is reversed — the earlier gain becomes taxable and is added back.
Section 54 is not a way to churn property tax-free. It is a way to move house without being taxed for it.
Section 54 vs Section 54F
| Section 54 | Section 54F | |
|---|---|---|
| What you SOLD | A residential house | Any OTHER asset — land, a plot, shares, gold, a shop, commercial property |
| What you BUY | A residential house in India | A residential house in India |
| How much you must reinvest | The capital GAIN only | The WHOLE net sale consideration — a far harder test |
| Partial reinvestment | Exempt to the extent reinvested | Proportionate exemption only — reinvest half the sale price, exempt half the gain |
| Other houses you may own | No restriction | You must not own more than ONE other residential house on the date of transfer |
| Timing — purchase | 1 year before, or 2 years after | 1 year before, or 2 years after |
| Timing — construction | Within 3 years | Within 3 years |
| Cap | ₹10 crore | ₹10 crore |
| Lock-in on the new house | 3 years | 3 years |
| CGAS deadline | Yes — by the ITR due date | Yes — by the ITR due date |
The 'whole sale consideration' requirement is what makes 54F so much harder than 54. On a Rs 2 crore sale with a Rs 60 lakh gain: Section 54 needs Rs 60 lakh reinvested. Section 54F needs the entire Rs 2 crore.
We have written this against the current position and checked it carefully. But tax turns entirely on your specific facts: your residential status, when you bought, when you sell, which regime you are on, and what else is in your return.
Note also that the Income Tax Act, 2025 now replaces the 1961 Act, and section numbering is changing even where the substance is not. We use the familiar numbers — 54, 54F, 24(b), 80C — because those are what people search for and what CAs still say. Confirm the current section references with your accountant.
Before you sell a property, pay a CA. On a transaction this size it is the best-value fee you will ever pay, and the cost of getting it wrong runs to lakhs.
Frequently asked questions
What is Section 54 exemption?
It exempts the long term capital gain from selling a residential house, if you reinvest that gain in another residential house — buying within 1 year before or 2 years after the sale, or constructing within 3 years. Capped at Rs 10 crore.
Do I have to reinvest the whole sale price under Section 54?
No — only the capital GAIN. That is the key difference from Section 54F, which requires the entire net sale consideration. On a Rs 2 crore sale with a Rs 60 lakh gain, Section 54 needs Rs 60 lakh reinvested; Section 54F would need the whole Rs 2 crore.
What is the Capital Gains Account Scheme, and why does it matter?
If you have not reinvested by the due date for filing your income tax return, you must deposit the unutilised gain into a CGAS account with a bank. Miss this and the exemption is lost entirely — even if you buy the perfect house well within the two-year window a year later. It is a purely administrative failure, it happens every year, and it is entirely avoidable.
Can I buy the new house before selling the old one?
Yes — up to one year before. This is badly underused. Most people actually move by finding the new place, buying it, and then selling the old one. If you bought a house in the last 12 months and are now selling your previous one, you may well qualify under Section 54 without realising it.
What happens if I sell the new house within 3 years?
The exemption is reversed — the earlier capital gain becomes taxable and is added back. Section 54 is a way to move house without being taxed for it, not a way to churn property tax-free.
