Capital-gains exemption calculator (54 / 54F / 54EC)

The tax on a property gain is not fixed. Reinvest the money the right way and you can cut it to nothing, or close. The law gives you three doors: put the gain into another house (Section 54), put the whole sale value from a non-house asset into a house (Section 54F), or park up to fifty lakh in capital-gains bonds (Section 54EC).

This calculator shows what each door saves you, and what is left to pay. Enter your gain and your reinvestment plan, and it does the arithmetic against the current 12.5% rate, so you decide with numbers rather than a rule of thumb.

What it does

Section 54: reinvest a house gain into another house, exemption up to the gain
Section 54F: reinvest the net sale consideration from other assets, proportionate exemption
Section 54EC: bonds up to ₹50 lakh (REC, PFC, IRFC; NHAI discontinued), 5-year lock
Tax saved under each route, and the tax still payable

The tax on a gain is a choice, not a fixed bill

Sell a property in India at a profit and the long-term capital-gains tax looks fixed: 12.5 percent of the gain, plus surcharge and cess. It is not fixed. The law hands you three ways to reinvest that gain and cut the tax, sometimes to nothing. Most sellers pay in full because nobody told them the doors existed, or told them too late to walk through one.

The three doors are Sections 54, 54F, and 54EC. This calculator shows what each saves on your numbers, and what is left to pay if you use one, two, or all three. The rule that governs all of them is timing: the reinvestment has to happen inside a window that starts at the sale, so the planning belongs before you sign, not after.

Section 54: roll a house gain into another house

If the asset you sold is a residential house, Section 54 lets you reinvest the capital gain into another residential house in India and exempt it. You need to buy the new house one year before or two years after the sale, or build it within three years. Reinvest an amount equal to or above the gain and the whole gain is exempt; reinvest less and the exemption is capped at what you put in.

Two refinements matter. You can split the gain across two houses, once in a lifetime, if the gain is up to two crore. And the reinvestment that counts for the exemption is capped at ten crore. For an NRI the new house must be in India, but the exemption is fully available. Work out the gain first with the property-sale TDS calculator, then size the reinvestment here.

Section 54F: sold something other than a house

Sold a plot, shares, or another long-term asset that is not a house? Section 54F applies, and it is stricter in one way. You must reinvest the whole net sale consideration, not just the gain, into one residential house to exempt the entire gain. Reinvest only part and the exemption is proportionate: the gain is exempted in the ratio of what you reinvested to the total consideration.

The calculator handles that proportion for you. It also respects the condition that you cannot own more than one house, other than the new one, on the date of sale. The reinvestment timelines mirror Section 54.

Section 54EC: park the gain in bonds

The third door does not need a property. Section 54EC lets you invest the gain in specified capital-gains bonds within six months of the sale, and exempt the amount invested. The rules to hold:

Cap: ₹50 lakh in a financial year, and this cap now spans the year of sale and the next year combined, so you cannot split a large gain across two years to double it.
Issuers: REC, PFC, and IRFC. NHAI stopped issuing 54EC bonds, so any adviser or page still naming NHAI is out of date.
Lock-in: 5 years. The money is illiquid for the term.
Interest: about 5.25%, taxable. Modest, and taxed as income.

54EC suits a gain up to fifty lakh where you do not want to buy another property. Above that, it caps out and the house routes do more.

Timing, and the account that saves a missed deadline

Every one of these exemptions runs on a clock that starts at the sale. If you have not completed the reinvestment by the date your return is due, you do not lose the exemption automatically. Deposit the unspent gain in a Capital Gains Account Scheme account at a bank before the filing deadline, and you preserve the exemption while you complete the purchase or construction inside the window. Miss both the reinvestment and the CGAS deposit, and the gain becomes taxable in full.

For an NRI selling from abroad, the sequence tightens further, because the buyer's TDS and the repatriation window interact with all of this. Plan the reinvestment before the sale, not in the scramble after. The repatriation calculator covers moving whatever is left out of India.

Where 66 MG Road fits

We run the exit for NRI owners: the gain computed, the Lower Deduction Certificate filed so the buyer does not lock up your money, and the reinvestment coordinated with a CA so the right exemption is claimed inside its window, with the CGAS deposit as a backstop if the new purchase slips. We do not give the tax opinion; the CA signs it. We run the paperwork and the timeline. We operate in Mumbai, Pune, Bangalore, Hyderabad, Chennai, and Gurgaon.

Common questions

How can I save capital-gains tax after selling property in India?

Reinvest the gain. Section 54 exempts a house gain reinvested in another house. Section 54F exempts a gain from other assets if you reinvest the net sale consideration in a house. Section 54EC exempts the gain, up to ₹50 lakh, invested in REC, PFC, or IRFC bonds within six months. NRIs can use all three by reinvesting in India.

What is the maximum I can invest in 54EC capital-gains bonds?

₹50 lakh in a financial year, and the cap now spans the year of sale and the following year together, so you cannot split a larger gain across two years. The bonds must be bought within six months of the sale, lock in for five years, and pay about 5.25% taxable interest. Issuers are REC, PFC, and IRFC.

Can NRIs claim Section 54 and 54EC exemptions?

Yes. Both are available to NRIs, provided the reinvestment (the new house under Section 54, or the bonds under 54EC) is in India. The exemptions cut the same 12.5% long-term capital-gains tax that a resident would pay.

What if I cannot reinvest before filing my return?

Deposit the unspent gain in a Capital Gains Account Scheme account at a bank before the return due date. This preserves the exemption while you complete the purchase or construction within the allowed window. If you neither reinvest nor deposit in time, the gain becomes fully taxable.

How accurate is this exemption calculator?

It applies the current 12.5% long-term rate with surcharge and cess, and models the Section 54, 54F, and 54EC exemptions including the ₹50 lakh bond cap and the 54F proportion. Eligibility conditions and timelines are strict, so confirm your specific plan with a chartered accountant before you commit the money.
