Capital Gains on Selling Ancestral Property in Kolkata: Cost, 2001 Value, 12.5% vs 20% Option and Exemptions
When you sell a house, flat or land in Kolkata that you inherited, the gain is long-term if the property was held for more than 24 months counting the previous owner’s period of holding, which it almost always is. Your cost is the previous owner’s cost, and if the property was acquired before 1 April 2001 you can use its fair market value on 1 April 2001 instead. Long-term gains are taxed at 12.5% without indexation, but resident individuals and HUFs selling land or buildings acquired before 23 July 2024 can choose 20% with indexation if that gives lower tax. You can save the tax by buying another house or investing in specified bonds within the time limits.
How the gain is worked out
| Item | Rule for inherited property |
|---|---|
| Holding period | Includes the period held by the previous owner |
| Cost of acquisition | The previous owner’s cost, or fair market value on 1 April 2001 if acquired before that date |
| 2001 value cap | The 2001 fair market value of land or building cannot exceed its stamp duty value on that date |
| Improvement cost | Costs incurred after 1 April 2001, by the previous owner or by you |
| Sale value | Actual price, or the stamp duty value if that is more than 110% of the price |
| Rate | 12.5% without indexation; or 20% with indexation for residents, for property acquired before 23 July 2024 |
Example
A flat in Ballygunge bought by your father in 1995 had a fair market value of ₹18 lakh on 1 April 2001, as supported by a registered valuer’s report. You sold it in financial year 2025-26 (Cost Inflation Index 376) for ₹1.6 crore.
| Option | Cost used | Gain | Tax before cess |
|---|---|---|---|
| 12.5% without indexation | ₹18 lakh | ₹1.42 crore | ₹17.75 lakh |
| 20% with indexation | ₹18 lakh × 376 ÷ 100 = ₹67.68 lakh | ₹92.32 lakh | ₹18.46 lakh |
Here the 12.5% option is lower. For property with a high 2001 value relative to the sale price, the indexation option often wins. Always work out both.
The 2001 valuation report
For old north and south Kolkata houses, the 2001 value is the biggest number in the calculation. Get a report from a registered valuer, supported by comparable sales and the circle rate as on 1 April 2001. The value cannot exceed the stamp duty value on that date, so check that first.
Several heirs selling together
Each co-owner computes the gain on their own share and files their own return. The buyer deducts TDS (1% for resident sellers if the property value is ₹50 lakh or more) separately for each seller. Make sure the sale deed shows each heir’s share and that mutation in the heirs’ names is complete before sale. Our guide to stamp duty in Kolkata explains the registration side.
Selling to a developer
Many old Kolkata houses are given to developers under a joint development agreement in exchange for flats. The gain is generally taxed in the year the completion certificate is issued, on the stamp duty value of your share of flats plus any money received. Read the agreement carefully, because money received upfront is taxed differently.
Saving the tax
- Buy a residential house: reinvest the gain in one house in India within 1 year before or 2 years after the sale, or construct one within 3 years. The exemption is capped at ₹10 crore of gain.
- Bonds: invest up to ₹50 lakh in specified long-term bonds within 6 months of the sale.
- Capital gains account: if you have not reinvested by the return due date, deposit the amount in a capital gains account scheme.
NRI heirs
If the heir is a non-resident, the buyer must deduct TDS on the gain at the higher non-resident rates. See our guide to an NRI selling a flat in Kolkata.

12.5% without indexation, or, for residents, 20% with indexation if the property was acquired before 23 July 2024, whichever is lower.
