How sections 54EC and 54F help you save capital gains tax in Mumbai
When a homeowner in Mumbai sells a property, the profit is taxable. For assets held for more than 24 months, the profit is treated as Long-Term Capital Gains (LTCG). Under the Finance Act 2024, it is taxed at 12.5% without indexation. For example, if a flat bought for ₹80 lakh in 2010 is sold for ₹3 crore today, the tax on the profit is ₹27.5 lakh before any planning. The Income Tax Act offers two specific exemptions that can reduce or eliminate this tax burden when sellers reinvest correctly, Section 54F and Section 54EC.
This blog by Piramal Realty explains how these sections work individually and together, the applicable timelines, what has changed under the Income Tax Act 2025, and the four mistakes that can cost Mumbai sellers their exemption.
What is the difference between Section 54, 54EC, and 54F?
The three sections cater to different types of sellers. Choosing the wrong one or failing to meet eligibility criteria can result in losing the exemption.

In simple terms, selling a residential house to buy another residential house falls under Section 54. If someone sells shares, gold, land, or commercial property to buy a new home, that falls under Section 54F. If you are not ready to buy a home, Section 54EC allows you to invest gains in government bonds instead. Many upgrade scenarios in Mumbai benefit from using 54F and 54EC together.
How does Section 54F work when you sell non-property assets to buy a home?
Section 54F offers a full long-term capital gains exemption when the entire net sale amount, not just the gains, is reinvested into one new residential house. This is a strong option for investors selling shares, gold, or commercial property to finance an upgrade to their home in Mumbai.
Key conditions:
The asset sold must be a long-term capital asset other than a residential house. The total sale amount must go into one residential property in India. Purchase must take place within one year before or two years after the sale date, and construction must be completed within three years. The seller must not own more than one residential house on the transfer date.
The exemption cap under Section 54F is ₹10 crore (from FY 2023-24 onwards) on the investment amount considered for the formula. This is important for high-end transactions in South Mumbai and Bandra, where property values can reach or surpass this amount.
Example: An investor sells listed shares for ₹3 crore, with an LTCG of ₹1.8 crore, and invests the whole ₹3 crore into a flat at Piramal Revanta. The entire ₹1.8 crore LTCG is exempt, resulting in zero tax. If she had invested only ₹2 crore, only two-thirds of the gain would be exempt.
How does Section 54EC work if you are not buying a home immediately?
Section 54EC allows sellers to earn a capital gains tax exemption by investing gains up to ₹50 lakh per financial year into designated 54EC bonds issued by NHAI or REC. No home purchase is necessary.
What you need to know about 54EC bonds (official issuer pages, nhai.gov.in for NHAI bonds and recindia.nic.in for REC bonds), the bonds must be invested within six months of the transfer date, not the end of the financial year or ITR deadline. There is a five-year lock-in, and early redemption triggers the full tax. The ₹50 lakh cap applies per financial year, so a sale in October allows for ₹50 lakh before March and another ₹50 lakh after April, totalling up to ₹1 crore if both investments occur within six months of the transfer. The interest, currently 5.25% p.a., is fully taxable as income.
Section 54EC is also effective when used with Section 54F, you can invest ₹50 lakh in bonds to shelter part of the gain and use the remaining amount for a home purchase under 54F.
What are the timelines you must not miss?
Missing a deadline forfeits the entire exemption, adding the LTCG back to taxable income for that year. This is not merely a paperwork issue, it has financial implications.

The capital gains account scheme (CGAS) is meant for the time between a sale and a home purchase. If you can't complete the home purchase before the ITR filing deadline (31 July), deposit the unused proceeds in a CGAS account at any scheduled bank. This preserves your Section 54F exemption while you complete the transaction. The funds must be used only for the property purchase within the specified time frame.
What has changed under the new Income Tax Act 2025, and what mistakes do sellers make?
The Income Tax Act, 2025, maintains the structure of Sections 54, 54F, and 54EC, with only minor changes to these exemptions. However, the sections have been renumbered in the new Act, so you should check the current section numbers with your chartered accountant when filing from FY 2026-27 onwards. References to the old section numbers are still valid for transactions completed before 1 April 2026.
The main change, already in effect from the Finance Act 2024, is that LTCG on property sales is now taxed at 12.5% without indexation, down from 20% with indexation. For properties bought before 2001, a stepped-up cost base applies. For the latest provisions, check the official Income Tax Department website at incometax.gov.in.
Four common mistakes that can lead Mumbai sellers to lose their exemption:
Missing the 54EC six-month window. The clock starts from the registration date, not the end of the financial year. Many sellers assume they have until 31 July.
Not using CGAS before filing. Sellers who haven't bought a new home by the ITR deadline often file for the exemption without placing funds in CGAS. This is legally invalid and will not be allowed during scrutiny.
Investing only the gain, not the full sale amount, under 54F. Section 54F offers a proportional exemption. If you invest ₹2 crore from a ₹3 crore sale, only two-thirds of the LTCG is exempt.
Selling the new property within three years. If the newly purchased home under 54F is sold before three years, the original exemption is fully revoked in the year of the new sale. Selling quickly after acquiring a property at Piramal Aranya eliminates any benefits.
The capital gains tax setup rewards sellers who plan ahead. For anyone upgrading to a premium home in Mumbai, such as at Piramal Mahalaxmi in South Mumbai, Piramal Aranya in Byculla, or Piramal Vaikunth in Thane, using sections 54F and 54EC together can significantly reduce tax bills. It's wise to get a tax opinion from a chartered accountant before making any large transactions.
Frequently Asked Questions
What is the ₹10 crore exemption cap, and does it affect most Mumbai buyers?➕
The ₹10 crore cap under Section 54F, effective from FY 2023-24, applies to the investment amount used in the exemption formula. Only the first ₹10 crore invested in the new residential property is considered when calculating the exempt portion of your long-term capital gain. Gains from investments over ₹10 crore are still taxable. Most buyers in Mumbai looking in the ₹2 to ₹8 crore range are not impacted by this cap. It mainly affects very high-end transactions in South Mumbai or Bandra, where the value of the new property exceeds ₹10 crore.
Which section applies if I sell my Mumbai flat to buy a bigger one, Section 54 or Section 54F?➕
Section 54 applies when you sell a residential house to buy another residential house. Section 54F applies when you sell a non-residential long-term asset, such as shares, gold, or commercial property, to fund a home purchase. Selling your Thane flat to move to Piramal Mahalaxmi falls under Section 54, not Section 54F.
What is the Capital Gains Account Scheme, and when should I use it?➕
The capital gains account scheme (CGAS) is a special bank deposit account that maintains your Section 54F exemption when you have not completed your home purchase by the ITR filing deadline. You should deposit the unused sale proceeds before 31 July and then withdraw them specifically for the property purchase within the set time frame. It is necessary, failing to use it when needed will invalidate the exemption claim.
Can I invest capital gains in an under-construction flat and still claim the exemption?➕
Yes. Under Section 54F, you can get a long-term capital gains exemption for under-construction properties, as long as the construction is completed within three years from the date of the original sale. A flat booked at Piramal Revanta or Piramal Vaikunth during construction qualifies, provided you receive possession within this three-year timeframe.
Can I claim Section 54F if the new flat is registered in my spouse's name?➕
This is legally contested. Strictly, the flat should be in your own name. But the Delhi High Court, in the Kamal Wahal case, and several tax tribunal rulings have allowed the Section 54F exemption even when the flat is in a spouse's name, as long as the money can be traced back to your own sale proceeds. Registering solely in your spouse's name risks disallowance, joint registration is safer. Consult a tax advisor first.
