Capital gains on a property sale: what to decide before you sign, not after

The reliefs available on a property sale are timing-sensitive. Most of them close on the day the transaction is executed.

How the gain is computed

A capital gain on immovable property is broadly the difference between the sale consideration and the cost of acquisition, adjusted for allowable improvement and transfer costs. Whether the gain is short-term or long-term depends on the holding period, and that classification changes both the rate and the reliefs available.

Because the computation depends on documents that may be decades old, gathering the acquisition record early is a practical necessity rather than a formality.

  • Original purchase deed and payment evidence
  • Records of capital improvements, with invoices
  • Brokerage and transfer costs incurred on the sale
  • Any prior claim of relief on the same asset

Why timing decides the outcome

Several reliefs under the Income-tax Act are conditional on reinvestment within defined windows, or on depositing unutilised amounts in a prescribed account before the return due date. These windows run from the date of transfer. A seller who takes advice after registration has already lost access to some of the planning that would have been available a month earlier.

Where a sale and a purchase are both planned, sequencing them correctly is often worth more than any negotiation on price.

TDS on the transaction

Purchase consideration above the prescribed threshold attracts tax deduction at source, and the rate differs where the seller is a non-resident. The obligation sits with the buyer, and errors create a liability that follows the buyer rather than the seller.

Both sides should confirm the applicable rate, the deposit deadline and the certificate requirements before funds move.

What to keep after the sale

Retain the registered deed, the computation working, evidence of any reinvestment relied upon, and the challans for tax deposited. If a query is raised in a later assessment year, this file is the entire defence.

Frequently asked

Does reinvesting in another property always remove the tax?

No. Reinvestment reliefs have conditions on the type of asset, the amount reinvested, the time window and how long the new asset is held. Each condition must be satisfied, and the relief can be withdrawn if the new asset is disposed of too early.

What if the acquisition documents are lost?

Certified copies can usually be obtained from the registration office, and other evidence of cost may be admissible. Start this early — retrieval takes time.
