Section 54 Capital Gains Exemption: The Complete Guide for AY 2026-27

The single most important exemption on a property sale

When a resident individual or Hindu Undivided Family (HUF) sells a residential house held long-term, Section 54 of the Income-tax Act, 1961 allows the long-term capital gain to be fully or partly exempt if it is reinvested in another residential house within prescribed time limits. Used correctly, Section 54 can reduce the tax on a Pune property sale to nil. Missed by a quarter, it can leave a multi-crore gain fully taxable.

This guide walks through every working part of the section — eligibility, the reinvestment windows, the Capital Gains Account Scheme bridge, the cap, and the rules around multiple new houses.

The five elements that must be satisfied

Section 54 applies only where all five conditions are met:

1. The asset transferred is a residential house property.
2. The seller is an individual or a HUF (resident or non-resident — Section 54 is not residency-restricted).
3. The gain is long-term — the house must have been held for more than 24 months before transfer (Section 2(42A)).
4. The reinvestment is in one residential house in India.
5. The reinvestment timing is within the prescribed windows.

Each is explored below.

Element 1 — what counts as a "residential house"

A residential house is a building used or capable of being used for residential purposes. It includes the land appurtenant. It does not include a plot of land that has not been built upon (for plots see Section 54F instead), or commercial property.

The asset transferred can have been let out before sale — that does not change its character as a residential house. What matters is the physical nature of the property and its capability of residential use.

Element 2 — eligible sellers

Section 54 is available to an individual and to a HUF — not to companies, LLPs, partnership firms or AOPs. Resident or non-resident — both qualify. A joint owner who is an individual qualifies for the exemption proportionate to their share.

Element 3 — long-term threshold

The property must have been held for more than 24 months to qualify as long-term under Section 2(42A) of the Income-tax Act. For inherited or gifted property, the period of the previous owner is added to your own period under Section 49(1) — which almost always pushes inherited residential property into long-term territory.

If held for 24 months or less, the gain is short-term and Section 54 does not apply (the gain is taxed at slab rate).

Element 4 — reinvestment in a residential house

The reinvestment must be in one residential house in India.

Three points of nuance:

• The new house must be in India. A house purchased abroad does not qualify (Finance Act 2014 amendment).
• The reinvestment is into one house — but the Finance Act 2019 amendment, retained through subsequent finance acts, gives a one-time option to invest in two houses in India if the long-term gain does not exceed ₹2 crore. The option, once used, cannot be exercised again in any subsequent year.
• For sales on or after 1 April 2023, the reinvestment that qualifies for Section 54 exemption is capped at ₹10 crore (Finance Act 2023 amendment). The portion of new-house investment above ₹10 crore is ignored for the Section 54 computation.

Element 5 — reinvestment timing

This is where most Section 54 claims succeed or fail.

For a purchase of an existing house:

• Within one year before the date of sale, or
• Within two years after the date of sale.

For construction of a new house:

• Within three years after the date of sale.

The dates are computed from the date of transfer of the original house. Date of transfer is generally the date of registered sale deed; for some structures it can be earlier under Section 2(47).

If the reinvestment timing is missed, the exemption is lost entirely for that portion of the gain.

The Capital Gains Account Scheme bridge

The return for the year of sale is generally filed before the two-year (purchase) or three-year (construction) reinvestment window has run its full course. Section 54(2) provides the bridge: any unutilised amount of the gain must be deposited into a Capital Gains Account Scheme (CGAS), 1988 account at a notified bank on or before the due date for filing the return under Section 139(1).

The deposit is treated as utilisation for the year of sale; the exemption is claimed in that year. The actual purchase or construction is then completed from the CGAS deposit within the window. Withdrawals are made by submitting Form C / Form D at the bank with proof of intended use.

If the CGAS deposit is not used in time, the unutilised amount becomes taxable in the year the window expires.

How the exemption is computed

Section 54 exempts the lower of:

• The amount of the long-term capital gain on the original house, or
• The amount invested in the new house (subject to the ₹10 crore cap from 1 April 2023).

If the new house costs more than the gain, the full gain is exempt and the surplus paid from your own funds creates no exemption issue. If the new house costs less than the gain, only that portion of the gain is exempt and the balance is taxable.

The cost of the new house includes the purchase consideration plus stamp duty and registration; for construction, it includes land cost plus construction cost actually incurred within the window.

A worked example

A Pune flat bought in 2010 for ₹40 lakh is sold in 2026 for ₹2.0 crore. Long-term capital gain (12.5% without indexation method post 23 July 2024 amendment) is approximately ₹1.6 crore.

Scenario A — buy new house for ₹2 crore within 2 years Investment of ₹2 crore covers the entire ₹1.6 crore gain. Section 54 exemption = ₹1.6 crore. Net taxable gain = nil.

Scenario B — buy new house for ₹1 crore within 2 years Investment of ₹1 crore covers ₹1 crore of the gain. Section 54 exemption = ₹1 crore. Net taxable gain = ₹0.6 crore → tax at 12.5% = ₹7.5 lakh (plus surcharge and cess).

Scenario C — file ITR by 31 July 2027, plan to construct by 2029 Deposit ₹1.6 crore in CGAS before 31 July 2027. Exemption claimed for AY 2026-27 = ₹1.6 crore. Construction completed by 2029 from CGAS — exemption stands.

Scenario D — same CGAS deposit, construction not completed by 2029 Unutilised CGAS amount becomes taxable in the year the window expires (AY 2030-31).

What disqualifies Section 54 even after claim

The exemption is withdrawn if the new house is transferred within three years of its acquisition or construction. The capital gain on the new house in the year of transfer becomes short-term, and the originally exempted gain is added back in computing the cost. This anti-abuse rule was designed to prevent quick churn.

Section 54 vs Section 54F — when to use which

Section 54 applies to sale of a residential house and reinvestment in a residential house — gain-based investment.

Section 54F applies to sale of any other long-term asset (plot of land, shares, gold, jewellery) and reinvestment in a residential house — net consideration-based investment. Conditions are stricter:

• The taxpayer must not own more than one residential house at the date of original transfer (other than the new house).
• The taxpayer must not purchase or construct another residential house within the prescribed window.

For a sale of an under-construction plot of land or a sale of shares followed by purchase of a flat, Section 54F applies, not Section 54.

Section 54 v 54EC — they stack

Section 54EC allows reinvestment of long-term capital gain (up to ₹50 lakh) in NHAI / REC / PFC bonds within six months of transfer. The bonds carry a 5-year lock-in.

Sections 54 and 54EC can be claimed together. A Pune seller with ₹2.5 crore long-term gain can use Section 54 for ₹2 crore (new house) and Section 54EC for ₹50 lakh (bonds) — total exemption ₹2.5 crore, taxable gain nil.

NRI sellers — Section 54 still applies

Section 54 is residency-neutral. An NRI selling a Pune flat can claim Section 54 by purchasing or constructing another house in India within the same time limits. The mechanics differ in two ways:

• TDS at sale will be under Section 195 (much higher than the 1% under Section 194-IA for resident sellers). A Section 197 lower-deduction certificate should be obtained before sale to fix the TDS at the post-Section-54 net tax — see our Section 197 NRI lower-TDS certificate guide.
• Repatriation of the unutilised sale proceeds beyond the Section 54 reinvestment requires Form 15CA Part C plus Form 15CB certification — see our Form 15CA / 15CB guide.

The reporting in the return

The exemption is claimed in Schedule CG of ITR-2 (or ITR-3 if the seller also has business income). Required disclosures:

• Date of transfer, full value of consideration, indexed cost (where 20% with indexation method is chosen for pre-23-Jul-2024 acquisitions).
• Exemption claimed under Section 54 with details of the new asset.
• CGAS deposit details where the new asset is not yet acquired.

The return must be filed by the due date to preserve the loss carry-forward right under Section 80 (relevant if other losses exist that would offset the gain).
