Section 54 Capital Gains Exemption: How to Save Tax on Sale of a House
If you sell a residential house after holding it for more than 24 months and reinvest the gains into another residential house, Section 54 of the Income Tax Act lets you claim a full or partial exemption from long-term capital gains tax. Here's how the reinvestment rules, timelines, and the lesser-known 'two houses' provision actually work.
Who Can Claim Section 54?
Section 54 applies only to individuals and HUFs who sell a residential house property held for more than 24 months (making the gain a long-term capital gain, or LTCG). The exemption is available when the capital gain (not the full sale proceeds) is reinvested in another residential house in India.
Reinvestment Timelines
- Purchase: a new residential house must be purchased either 1 year before or 2 years after the date of transfer of the original house
- Construction: if constructing a new house, construction must be completed within 3 years from the date of transfer
- The new property must be located in India (properties purchased abroad do not qualify)
How Much Exemption Do You Get?
The exemption is the lower of:
- The amount of long-term capital gain, OR
- The cost of the new residential house (including construction cost, if applicable)
The 'Two Houses' Rule (Since Budget 2019)
Earlier, Section 54 exemption was available only for reinvestment in one residential house. Since Budget 2019, a taxpayer can claim exemption by investing the capital gain in two residential houses in India — but only if the long-term capital gain does not exceed ₹2 crore, and this option can be exercised only once in the taxpayer's lifetime.
Capital Gains Account Scheme (CGAS)
If you sell the house before the end of the financial year but haven't yet reinvested the gain in a new property by the time you file your ITR (due date), you must deposit the unutilized amount in a Capital Gains Account Scheme (CGAS) account with a notified bank before the ITR due date to claim the exemption provisionally. The amount must then be utilized for purchase/construction within the overall Section 54 timeline (2 years for purchase, 3 years for construction from the date of original transfer).
| Situation | What to Do |
|---|---|
| Already purchased new house by ITR due date | Claim exemption directly; no CGAS needed |
| Not yet purchased/constructed by ITR due date | Deposit unutilized gain in CGAS before filing ITR |
| Amount in CGAS not utilized within timeline | Becomes taxable as LTCG of the year the timeline expires |
3-Year Lock-In on the New House
If the new residential house (in which you claimed the Section 54 exemption) is sold within 3 years of its purchase/construction, the exemption claimed earlier is withdrawn and added back to the cost of the new house is reduced by the exemption amount when computing capital gains on its sale — effectively recapturing the earlier tax benefit.
Section 54 vs Section 54F vs Section 54EC
Section 54 applies when the asset sold is itself a residential house. If you're selling a different type of asset (land, shares, gold) and reinvesting in a house, that's Section 54F. If you'd rather invest in specified bonds instead of property, see Section 54EC.
