Capital gains tax calculator for selling a flat or plot

Property held more than 24 months is a long-term asset. For sales after 23 July 2024 the long-term rate is 12.5% without indexation; for property acquired before that date, resident individuals may instead choose 20% with indexation if it gives lower tax. Short-term gains are taxed at your slab rate. This estimator computes both routes and the exemption available if you reinvest in another home.

How it is calculated

Gain = sale price − transfer expenses − purchase cost − improvement cost. Long-term (held over 24 months): tax at 12.5% without indexation; for property acquired before 23 July 2024, resident individuals may use 20% on the indexed gain (cost × CII of sale year ÷ CII of purchase year) if lower. Reinvestment in one residential house within the time limits exempts that much gain (section 54, cap ₹10 crore). Short-term gains are added to income and taxed at slab. 4% health and education cess is added; surcharge is ignored.

Worked example

Bought 2015 for ₹45 lakh, improved by ₹3 lakh, sold 2026 for ₹90 lakh with ₹90,000 expenses: gain ₹41.1 lakh → ₹5.34 lakh at 12.5%; indexed cost ₹71 lakh gives a gain of ₹18.1 lakh → ₹3.75 lakh at 20%, so indexation wins. Reinvesting ₹18.1 lakh in a new flat within two years reduces the tax to nil.

Frequently asked questions

What is the capital gains tax rate on property in India now?

12.5% without indexation on long-term gains (held over 24 months). Property bought before 23 July 2024 can alternatively use 20% with indexation if that gives lower tax. Short-term gains are taxed at your slab rate.

How can I save capital gains tax on selling a flat?

Reinvest the gain in one residential house within 2 years (or construct within 3) under section 54, or invest up to ₹50 lakh in NHAI/REC bonds within 6 months under section 54EC. Park unused amounts in a Capital Gains Account Scheme before the return filing date.

Does the buyer's TDS cover my capital gains tax?

The 1% TDS is only an advance; you compute the actual gain in your return and pay or claim the difference.
