Why these sections matter
When you sell a long-term capital asset (held more than 24 months for property, 12 months for listed shares), the gain is taxed at LTCG rates. For property after July 23, 2024, that's 12.5% without indexation OR 20% with indexation (you pick the lower one).
Sections 54 and 54F let you avoid this tax entirely if you reinvest the gain in another residential property within specified time windows.
Section 54: For residential-to-residential sales
### When it applies You sold a residential property held for more than 24 months. Gain is LTCG.
### What you do Buy a new residential property within: - 2 years AFTER the date of sale (purchase), OR - 1 year BEFORE the date of sale (purchase made before sale also qualifies), OR - 3 years AFTER the date of sale (if constructing new property)
### Exemption amount - If new property cost ≥ LTCG amount: Full LTCG exempt from tax - If new property cost < LTCG: Only the proportion invested is exempt
### Worked example Sold ancestral property in May 2026 for ₹2 crore. Indexed cost: ₹50 lakh. LTCG = ₹1.5 crore.
Buy a new flat in Bengaluru for ₹1.8 crore in October 2026. - LTCG = ₹1.5 crore. New property cost (₹1.8 crore) > LTCG. - Full ₹1.5 crore LTCG exempt under Section 54. - Tax saved: ₹1.5 cr × 12.5% × 1.04 = ₹19.5 lakh
Section 54F: For other-asset-to-residential sales
### When it applies You sold any other long-term capital asset (shares, bonds, gold, plot of land, second house) NOT covered by Section 54. Gain is LTCG.
### What you do Reinvest the net consideration (full sale value, not just gain) in residential property within the same 1/2/3-year windows as Section 54.
### Critical difference from Section 54 - Section 54: Reinvest the gain to save tax - Section 54F: Reinvest the net sale value to save tax
This is harsh: if you sold ₹1 crore worth of shares with ₹60 lakh gain and want full exemption, you must invest the FULL ₹1 crore in property — not just ₹60 lakh.
### Other 54F conditions - You must NOT own more than 1 residential property (other than the new one) on the date of sale - New property must not be sold within 3 years (else exemption reversed) - New property cannot be purchased within 1 year before sale OR 2 years after, in addition to existing residential property
### Worked example (Section 54F) Sold listed shares worth ₹50 lakh. Cost basis: ₹15 lakh. Gain: ₹35 lakh. Net consideration: ₹50 lakh.
Buy a flat for ₹50 lakh within 2 years. - Full ₹35 lakh LTCG exempt under 54F.
But if you buy a flat for ₹40 lakh: - Proportional exemption = ₹35L × (₹40L / ₹50L) = ₹28L exempt - Taxable gain = ₹7L → tax at 12.5% = ₹91,000
The Budget 2023 cap (now ₹10 crore)
Pre-2023, you could exempt unlimited gain through 54/54F. Budget 2023 capped the new property investment at ₹10 crore. So if your gain is ₹20 crore, only the first ₹10 crore is exempt; the rest is taxed.
This is rarely an issue for normal taxpayers — it targets ultra-HNI exemption planning.
Capital Gains Account Scheme (CGAS): the time-buyer
Found a buyer for your old property but haven't bought a new one yet? CGAS lets you park the gain temporarily without losing exemption.
### How it works - Open a CGAS account at any nationalized bank (SBI, BoB, etc.) - Deposit the unused gain BEFORE the ITR filing deadline of the year of sale (typically July 31) - Money sits there earning ~7% interest until you withdraw to buy/construct property - Withdraw within 2/3 years to buy/construct as planned
### Two CGAS variants - Type A (Savings deposit): Earns standard savings rate (~3%). Withdraw anytime. - Type B (Term deposit): Earns FD-equivalent rate (~6.5-7%). Slightly less flexible withdrawal.
### What if you don't use CGAS money? - Used within 2/3 years for property: Exemption stands - Not used within 2/3 years: Gain becomes taxable in the year window expires (e.g., you parked in 2026; window expires 2029; gain taxed in FY 2029-30 at then-current LTCG rate)
Common questions
### Q: Can I use Section 54 if the new property is in the name of my spouse? A: Under contention. CBDT and most courts say new property MUST be in the seller's name. Some lower courts allow joint with spouse. Conservative: keep it in your own name to avoid scrutiny.
### Q: What if I sell the new property before 3 years? A: The exemption is reversed. The earlier saved tax becomes payable in the year of sale. Plus, the gain on the new property sale is treated as STCG.
### Q: Can I claim 54F if I'm constructing a new house? A: Yes. The 3-year construction window applies. You must complete construction (with possession or completion certificate) within 3 years.
### Q: NRI selling Indian property — does 54/54F apply? A: Yes, both apply to NRIs equally. New property must be in India.
### Q: What if I deposit in CGAS but use it for non-property? A: The exemption is lost. Tax becomes payable retroactively in the year of original sale (with interest).
### Q: Do I have to invest immediately, or can I wait? A: You have time. 2 years (purchase) or 3 years (construction) after sale. Many people use this window strategically.
Section 54EC: The bond alternative (mention)
If you don't want to buy property but still want to save LTCG tax on property sale, Section 54EC lets you invest up to ₹50 lakh in NHAI / REC / PFC tax-saving bonds within 6 months of sale. Lock-in: 5 years. Returns ~5.25%. Useful when: - You're senior, don't want a new property - You've used all your residential property exemption already - You want guaranteed return + tax saving
54EC is independent of 54/54F — you can claim them separately for the same sale.
Common mistakes
1. Claiming both 54 AND 54F on the same property. You pick one based on what you sold. 2. Buying property in spouse's name. Risky for exemption. 3. Selling new property within 3 years. Reverses everything. 4. Missing CGAS deadline. If you don't deposit by ITR filing date, exemption is lost. 5. Using new property as commercial after a few years. Keeps exemption only if it's residential at the time of acquisition; subsequent change is generally OK but consult CA. 6. Forgetting Section 54B (agricultural land). If you sold agricultural land, Section 54B (not 54F) lets you reinvest in agricultural land for exemption.
Quick decision tree
- Sold residential property → Buy residential within 2-3 years → Section 54
- Sold shares/gold/second house → Buy residential property → Section 54F
- Want bonds instead of property → Section 54EC (₹50L cap, 5-year lock)
- Time-pressed, can't decide → Park in CGAS, use within 2-3 years
