Selling a ₹15 lakh Flat for ₹50 lakh: The Tax

On a flat bought at ₹15 lakh and sold at ₹50 lakh after 15 years, the gain is ₹35 lakh. As a long-term gain it is taxed at 12.5%, giving roughly ₹4,37,500 before exemptions.

The number that surprises sellers is not the tax rate. It is that the tax is due whether or not the money is still in the account when the return is filed.

The calculation

Brokerage, stamp duty you paid on purchase, and the cost of any capital improvements are deductible from the gain. Keep the receipts — assessing officers ask for them, and a claimed improvement without proof is disallowed.

Three ways to reduce it legally

Section 54 — buy another house. Reinvest the gain (not the whole sale value) in one residential property in India, bought within one year before or two years after the sale, or constructed within three. Do that fully and the ₹4,37,500 liability goes to nil.

Section 54EC — bonds. Up to ₹50 lakh into NHAI or REC bonds within six months, locked for five years. Useful when you do not want another property.

The Capital Gains Account Scheme. If the return is due before you have reinvested, park the gain in a CGAS account at a bank and claim the exemption anyway. Miss this and the exemption is lost even if you buy later.

What you can deduct from the gain

The cost of acquisition is not just the price on the sale deed. You may add the stamp duty and registration you paid when buying, the brokerage on both purchase and sale, legal fees, and the cost of capital improvements — a new roof or an added room, though not repainting or routine repairs.

Keep the invoices. An improvement claimed without documentation is routinely disallowed, and the difference on a gain this size is real money.

What sellers get wrong

They forget that the buyer's 1% TDS needs their PAN — without it, the deduction runs at 20% and reclaiming it is slow. They spend the proceeds and find the tax due at filing. And joint owners assume one return covers it; each owner declares their own share.

If you are an agent guiding a seller through this, the seller guides cover the conversation and the paperwork order.
