Sec 54 vs Sec 54F vs Sec 54EC — capital gains exemption decision tree
Three exemptions cut long-term capital gains tax: Sec 54 when you sell a house and buy another; Sec 54F when you sell another asset and buy a house with the net proceeds; Sec 54EC when you put up to ₹50 lakh of land or building gains into specified bonds within six months. Secs 54 and 54F cap at ₹10 crore.
The three sections at a glance
| Section | Asset sold | Reinvest in | Cap |
|---|---|---|---|
| Sec 54 | Residential house (held > 2 yrs) | Another residential house in India | Up to ₹10 Cr (FA 2023 cap) |
| Sec 54F | Any other long-term capital asset (equity, gold, land) | One residential house in India | Up to ₹10 Cr; full net consideration must be invested |
| Sec 54EC | Long-term capital asset (any, post FA 2018: only land/building) | NHAI / REC / IRFC / PFC bonds | ₹50 L per FY |
Sec 54 — residential to residential
The classic. Sell a house held more than 24 months, reinvest the capital gain (not the sale price) into another residential house within:
- 1 year before the sale, or
- 2 years after the sale (for purchase), or
- 3 years after the sale (for construction)
FA 2023 imposed a ₹10 Cr ceiling per assessee. Above that, the excess gain is taxable at 12.5% LTCG plus surcharge/cess. FA 2019 allowed (one-time, lifetime) investment in two houses if the gain is ≤ ₹2 Cr — useful when splitting an inheritance.
Sec 54F — selling anything except a house
The trap. Sec 54F requires you to invest the full net consideration — not just the gain. So if you sell ₹2 Cr of equity with a ₹1.5 Cr gain, you must buy a ₹2 Cr house (not a ₹1.5 Cr one) to fully exempt. Invest only ₹1.5 Cr and you get a proportional exemption of (1.5 / 2) × gain = 75%.
Other Sec 54F conditions:
- You can own at most one other residential house on the date of transfer (excluding the new one)
- You can't sell the new house for 3 years (or the entire exemption reverses and becomes taxable)
- Same 1-year-before / 2-year-after / 3-year-construction window as Sec 54
Sec 54EC — the safe-harbour bond route
Sold land or a building? Park up to ₹50 L of the gain into 5-year non-transferable bonds issued by NHAI, REC, IRFC or PFC within 6 months of the sale. Interest is taxable (~5.25% p.a. currently), but the gain itself is exempt.
FA 2018 narrowed Sec 54EC — now it's only for land/building gains, not for equity, gold, or other capital assets. The ₹50 L cap is per assessee per FY (FA 2017 tightened from "per transaction" to "per assessee").
The CGAS escape hatch — when the deal isn't done by ITR deadline
If you haven't bought/built the new house by the ITR filing date (31 July of the AY), deposit the unused amount into a Capital Gain Account Scheme with any nationalised bank before the ITR due date. The deposit "counts" as utilised investment for Sec 54/Sec 54F.
You then have the full 2-year / 3-year window from the original sale to withdraw and complete the purchase/construction. If it doesn't happen, the unutilised CGAS amount is taxable in the year the window expires. See our separate brief on CGAS mechanics.
📌 Common error: Filers assume Sec 54 and Sec 54F can be stacked. They can't — you must elect one. If you sell two assets (e.g. a flat + listed shares) in the same year, Sec 54 covers the flat gain and Sec 54F could cover the equity gain — but only if you buy one new house big enough to absorb both invested amounts. Two simultaneous purchases under both sections fails the "one residential house" requirement.
The decision tree
- What did you sell? Residential property → Sec 54 lane. Anything else → Sec 54F lane (if you want to buy a house) or Sec 54EC (if it's land/building and you want bonds).
- How large is the gain? Above ₹10 Cr → only ₹10 Cr exempt under Sec 54/54F. Up to ₹50 L → Sec 54EC works neatly if land/building.
- How quickly will you redeploy? Within 6 months → Sec 54EC (bonds locked 5 years). Within 2-3 years → Sec 54 / Sec 54F (CGAS in the meantime).
- Do you already own residential property? One house → Sec 54F still works. Two or more → Sec 54F is blocked; you can only use Sec 54 (sale of another residential house).
The Finclar take
For founders selling pre-IPO equity in a windfall, Sec 54F is the obvious move — but the "full net consideration" rule and 3-year holding lock-in make it inflexible. For retirees swapping a portfolio of equity LTCG for a single home, Sec 54F + CGAS gives you 2-3 years to find the right property. For land/building deals up to ₹50 L gain, Sec 54EC is the cleanest exit. For everything else, do the math on each section's effective tax saving net of the lock-in cost — sometimes paying the 12.5% LTCG today is simpler than locking ₹10 Cr in a house you don't actually want.
