Section 54 Exemption: Save Tax on Your Home Sale

If you sell your old house and buy or build a new one, Section 54 can save you lakhs in capital gains tax. But timing, construction deadlines, and CGAS rules matter hugely — miss one step and the taxman comes calling.

Here's what happened: Section 54 of the Income Tax Act lets homeowners avoid LTCG tax by reinvesting sale proceeds into a new residential property, with a 3-year deadline for self-construction projects.. Income tax tribunals have consistently ruled that construction started before the old house is sold can still qualify, as long as completion happens within 3 years of the sale date.. If the new property is not ready before the ITR filing deadline, taxpayers must deposit unused gains in a Capital Gains Account Scheme (CGAS) at an authorised bank to preserve the exemption..

What you should do: Calculate your sale date precisely — all Section 54 deadlines (2 years for purchase, 3 years for construction) run from this date, not the agreement or registration date.. Open a Capital Gains Account Scheme (CGAS) at any designated public sector bank before your ITR filing deadline if your new home will not be ready in time — deposit the gains there to keep the exemption alive.. Maintain a paper trail of all construction expenses — dated invoices, contractor agreements, and bank payment proofs — as the Income Tax Department may demand documentary evidence during scrutiny..

If you invest only part of the capital gain in the new property, the exemption is proportional — you pay tax only on the uninvested portion, not the entire gain.
