Formula used
Inheriting property is not itself a taxable event. Tax arises when the property is sold, and the computation runs on the previous owner's position rather than yours. The cost of acquisition is what the previous owner paid, and the holding period is counted from their purchase, which is why an inherited property is almost always long term even if you received it recently. Where the previous owner acquired the property before 1 April 2001 the taxpayer may substitute the fair market value as at that date where it is higher than actual cost, and the cost inflation index for the 2001-02 base year is 100. Only capital improvements incurred on or after 1 April 2001 are counted. For property acquired before 23 July 2024 a resident may choose between twelve and a half per cent without indexation and twenty per cent with it. A lower rate does not automatically mean lower tax: indexation wins only where the gain is small relative to cost, and the flat rate wins on large gains.
Example calculation
A property inherited from a parent who bought it in 1990 for Rs 2,00,000 is sold for Rs 1 crore, with Rs 2,00,000 of brokerage. A valuer puts its fair market value on 1 April 2001 at Rs 8,00,000, which is higher than actual cost, so that becomes the cost of acquisition. Without indexation the gain is Rs 92,00,000 and the tax at twelve and a half per cent is Rs 11,50,000. With indexation the cost becomes Rs 8,00,000 multiplied by 384 over 100, or Rs 30,72,000, giving a gain of Rs 67,28,000 and tax at twenty per cent of Rs 13,45,600. Here the flat rate is cheaper by nearly two lakh rupees, which surprises people who assume a long holding always favours indexation.
How to use this calculator
- Enter the sale price and the transfer expenses you bore on the sale.
- Enter what the previous owner actually paid for the property.
- If they acquired it before 1 April 2001, enter the fair market value as at that date and leave the acquisition index at 100.
- If they acquired it later, enter the notified cost inflation index for that year instead.
- Enter the cost inflation index for the year of sale and any improvements made after April 2001.
- Compare the two routes and check whether the indexation choice is available to you.
Important assumptions
- The cost of acquisition is the previous owner's cost, or the 1 April 2001 fair market value where that is higher.
- The holding period runs from the previous owner's acquisition, making the gain long term.
- Only improvements made on or after 1 April 2001 are counted.
- The choice between the two routes is available only for property acquired before 23 July 2024.
- Surcharge, cess and exemptions under sections 54 and 54EC are not applied.
Common mistakes to avoid
- Using the date of inheritance as the date of acquisition, which wrongly makes the gain short term.
- Treating the cost of acquisition as nil because the inheritor paid nothing.
- Claiming the 2001 fair market value for a property the previous owner bought after April 2001.
- Including improvements made before April 2001, which are not counted.
- Assuming the lower headline rate always produces the lower tax bill.
Four rules that generic capital gains tools get wrong
A standard capital gains calculator asks for your purchase price and purchase date. Neither figure exists for inherited property, and substituting the date of inheritance produces a short-term computation and a much larger tax bill. The correct treatment reaches back to the previous owner for both the cost and the holding period, permits a fair market value substitution for pre-2001 acquisitions, and counts only post-2001 improvements. Getting any one of those wrong changes the answer materially, which is why this computation deserves its own tool rather than a field on a general one.
- Cost is the previous owner's, not nil and not yours.
- Holding period runs from their purchase.
- Fair market value on 1 April 2001 may be substituted.
- Only improvements after April 2001 count.
