Section 54F Trap: Is Your ₹10Cr CIBIL Safe?

If you sell a non-residential asset and park capital gains in a Capital Gains Account Scheme but fail to reinvest in a home within the deadline, the tax exemption disappears and you owe the government capital gains tax — often a shock at filing time.

Here's what happened: Section 54F lets you skip Long Term Capital Gains tax on selling shares, gold, or plots — if you reinvest proceeds into a residential property within prescribed deadlines.. Unused funds parked in a Capital Gains Account Scheme (CGAS) that are not reinvested within 2 years (purchase) or 3 years (construction) become fully taxable as LTCG in the year the deadline lapses.. LTCG on non-residential assets is taxed at 20% with indexation (or 12.5% without, post-Budget 2024), meaning a ₹50 lakh gain left unused could trigger a ₹10 lakh tax bill..

What you should do: Check your CGAS account balance and reinvestment deadline right now — missing it by even one day makes the entire exemption void.. If you cannot buy property in time, consult a CA about whether constructing a house on an existing plot qualifies and extends your window to 3 years.. File your ITR correctly in the year the CGAS deadline lapses — declare the unclaimed exemption as taxable LTCG to avoid interest and penalty under Sections 234A/234B..

You can open a CGAS account in any nationalised bank before your ITR filing due date — not just before the property purchase — giving you breathing room while keeping your exemption intact temporarily.
