Apartment Registration in 2025 Did Not Reset the 2013 Clock

A Mumbai chartered accountant told a client who sold a ₹30 lakh flat in December 2025 that the ₹7 lakh gain can attract no tax. The buyer had paid the builder ₹23 lakh in 2013, taken possession that year, and got the apartment registered only in August 2025, then sold it the same year. The year of acquisition for that sale is 2013, the date of the agreement, not the date on the deed.

That one date does two jobs the 2025 registration cannot. It makes the sale long-term. It also keeps the older indexation choice that can wipe the bill.

A Four-Month Flip After a Twelve-Year Gap

On paper the file looks like a 2025 purchase flipped before the year was out. Full consideration of ₹23 lakh went to the builder in 2013. Possession followed that year, still without a registered title. The sale deed was stamped in August 2025 at the same ₹23 lakh, and the apartment went for ₹30 lakh in December 2025.

If the tax office treated August 2025 as the purchase date, the hold would fall well short of 24 months. The ₹7 lakh would then be short-term capital gains, added to other income and taxed at the seller’s slab rate, with no indexation at all. Mahesh Nayak, a chartered accountant at CNK & Associates, said the law does not start the clock at registration.

THE DATES THAT DECIDE THIS BILL

1. 2013: Pays the builder ₹23 lakh, takes possession, and holds an agreement or allotment letter for the flat.
2. 23 July 2024: Finance (No. 2) Act, 2024 cuts the default long-term rate to 12.5% and removes indexation, with a narrow grandfathering rule for older land and buildings.
3. August 2025: Registers the apartment for ₹23 lakh, the 2013 price.
4. December 2025: Sells the apartment for ₹30 lakh, a nominal gain of ₹7 lakh.

Twelve years of an unregistered title is still a mess for a buyer, a lender, or a society. It is not, on these facts, a new acquisition for capital gains.

High Courts Date Acquisition to the Allotment Letter

Nayak’s advice rests on a line the Central Board of Direct Taxes drew in 1986 and that high courts have applied to builder flats ever since. In Circular No. 471, dated 15 October 1986, the Board said an allottee under the Delhi Development Authority’s self-financing scheme gets title when the allotment letter is issued. Payment of later instalments is follow-up. Taking possession is a formality.

The allottee gets title to the property on the issuance of the allotment letter and the payment of instalments is only a follow-up action and taking the delivery of possession is only a formality.

CBDT Circular No. 471, 15 October 1986

That circular was written for DDA construction and for the old sections 54 and 54F. Courts then used the same logic for the holding period. The Bombay High Court in PCIT v. Vembu Vaidyanathan, decided in January 2019, held that the allotment date is the date on which a purchaser of a residential unit acquires the property. The Punjab and Haryana High Court in Vinod Kumar Jain v. CIT and the Delhi High Court in CIT v. Kuldeep Singh have said the same of allotment letters, not possession letters.

The Mumbai bench of the Income Tax Appellate Tribunal has applied that holding to gaps even longer than this one. In D.K. Brothers, an office at the Bharat Diamond Bourse was allotted on 28 January 1992 and registered only on 15 September 2010. The assessing officer used the registration date. The tribunal took allotment as the acquisition date and knocked out a short-term assessment. A later circular, No. 672 dated 16 December 1993, told officers to treat co-operative and other builder schemes like the DDA scheme when the terms are similar.

Nayak’s caveat is the one that matters in this file. The 2013 clock runs only if the seller had an agreement or an allotment letter that identified the apartment when possession was taken. A bare payment with no paper is a weaker case. Where that paper exists, the allotment letter confers title for capital gains even if the sub-registrar stamps the deed a decade later.

When Does a Property Sale Become Long-Term?

Immovable property is long-term if it is held for more than 24 months before the transfer. The Income Tax Department’s own note says that 24-month test applies to land and buildings whether the sale is before or after 23 July 2024. Listed shares use 12 months. A general 36-month rule that still appears in older explainers does not govern a house sale.

Counted from August 2025, this sale is short. Counted from 2013, it is long by a wide margin. Long-term status is what opens the door to the 2024 grandfathering rule. Short-term gains on a house still go into the slab, and indexation is not available on a short-term asset. Getting the year of acquisition wrong does not only change a rate. It changes the whole head of income.

The letter-writer also wrote of possession “since 2023” after describing possession in 2013. Nayak worked from the 2013 agreement and possession. Anyone in this position should put the allotment letter, the payment trail, and the possession letter in one folder before the return is filed, because those are the dates the officer will test.

Indexation Turns ₹23 Lakh Into ₹39.3 Lakh

From 23 July 2024, long-term gains on a transfer are taxed at 12.5% and indexation is off the computation. For a resident individual or Hindu Undivided Family selling land or a building acquired before that date, a second proviso to section 112 says any excess of the new-law tax over the old-law tax is ignored. In practice the seller works the bill both ways and pays the lower one.

The December 2025 sale falls in financial year 2025-26. CBDT Notification No. 70/2025, dated 1 July 2025, put the notified cost inflation index of 376 on that year. The index for 2013-14, the year of the agreement, is 220. Indexed cost is ₹23,00,000 × 376 / 220, which is ₹39.3 lakh. The sale price is ₹30 lakh. Under the old method there is no gain left to tax.

THE TWO WAYS TO TAX A ₹7 LAKH GAIN

The first method produces ₹87,500 before surcharge and the 4% health and education cess. The second produces nil. Because the new-law tax is higher, the excess is ignored and the payable figure is nil. Nayak put it plainly: opt to be taxed at 20% after indexation, and there would be no tax payable on the gains.

A February 2026 note in The Chartered Accountant, the journal of the Institute of Chartered Accountants of India, stresses that this relief is a cap on tax, not a rewrite of the gain itself. For transfers on or after 23 July 2024, indexation applies only at the tax stage. If the indexed cost sits above the sale price, the seller does not walk away with a long-term loss to set off or carry forward. The ₹7 lakh is still a gain on the computation. The grandfathering rule simply refuses to collect more tax than the old 20% formula would have collected, which in this file is zero.

That is the quiet part of the 2024 change. Inflation already ate this “profit.” The indexed cost of ₹39.3 lakh is higher than the ₹30 lakh the buyer paid. The old formula recognised that. The new 12.5% formula would have taxed the rupee difference anyway. The 2013 date is what lets the seller pick the formula that follows inflation.

The Old Rate Is Not Open to Everyone

The dual option is narrower than the headline 12.5% rate. It is not a general right to index every old asset. It is a comparison of two tax figures on one class of property, for one class of seller.

WHO CAN STILL USE THE 20% FORMULA

• The seller: Only a resident individual or a resident Hindu Undivided Family.
• The asset: Land, a building, or both, not gold, unlisted shares, or a debt fund.
• The purchase date: The property must have been acquired before 23 July 2024.
• The sale date: The transfer must fall on or after 23 July 2024.

A non-resident who sells Indian land or a flat after that cutoff pays 12.5% without indexation, even if the asset is old. The Department’s own worked example uses a non-resident who bought land in 2006 and sold it in December 2024: grandfathering is switched off because of residence, not because of the calendar. Companies, firms and LLPs are outside the proviso in the same way.

Budgets after 2024 did not rewrite this fork. The Department’s capital-gains pages, updated for the Finance Act, 2026, still describe the 12.5% default, the 24-month hold for a house, and the resident-only cap for older land and buildings. A seller who registered a 2013 flat after 23 July 2024 and assumed indexation had died is reading the wrong date on the wrong document.

Stamp duty, the annual property tax, and a 12.5% levy on the way out already sit on the same house. For this file the third charge is the one that can go to nil, but only if the 2013 paper is on the return. Treat the 2025 deed as the purchase date and the slab takes over.

Keep the Allotment Letter With the Sale Deed

The officer who processes a property sale does not start with the registered deed. On lower-deduction applications for non-residents, one assessing officer’s 2025 checklist asked for the purchase agreement, the builder’s possession letter and the share certificate “for considering the indexation,” plus the allotment letter where section 54 was claimed. The registered sale deed was on that list too. It was not the only date-bearing page.

That matches the case law. Allotment, then instalments, then possession, then registration is the sequence Circular 471 described. A 12-year gap between the first and the last step is ugly for title insurance and for a home loan, and it can inflate stamp duty when a 2013 price is presented to a 2025 registrar. It does not, by itself, move the capital-gains clock.

The seller in this query still has to show the 2013 agreement or allotment letter, the ₹23 lakh trail, and possession in 2013. Without those, an officer can try the August 2025 date and a short-term assessment. With them, Nayak’s arithmetic holds: long-term from 2013, indexed cost of ₹39.3 lakh, and a choice that takes the tax on ₹7 lakh to nil.

The deed that finally appeared in August 2025 is what let the apartment be sold. It is not what decided the year of acquisition, the 24-month test, or which side of 23 July 2024 this seller is on. Those three answers were sitting in the 2013 file the whole time.

Frequently Asked Questions

Can a Non-Resident Use the 20% Indexation Option on a House?

No. The second proviso to section 112 is limited to resident individuals and resident Hindu Undivided Families. A non-resident who sells land or a building on or after 23 July 2024 pays 12.5% on the unindexed gain even if the property was bought years earlier, which is why the Department’s own land-sale illustration switches grandfathering off for a non-resident seller.

If Indexation Pushes Cost Above the Sale Price, Can I Carry Forward a Loss?

No. Grandfathering compares two tax figures and ignores the excess of the 12.5% bill over the old 20% bill. It does not recompute the gain with indexation for set-off. When indexed cost exceeds the sale price, as with ₹39.3 lakh against ₹30 lakh here, the payable tax can fall to nil, but the law does not hand the seller an indexed long-term loss to park against other income or to carry forward.

Do Co-Operative Housing Allotments Get the Same Acquisition Date as DDA Flats?

Yes, if the scheme works like the DDA self-financing scheme. Circular No. 672, dated 16 December 1993, told officers to treat allotments by co-operative societies and other institutions as construction for sections 54 and 54F when the terms match Circular 471, and tribunals have used that same likeness test when they fix the holding period from the allotment letter rather than from registration.

What Cost Inflation Index Applies if I Sell in Financial Year 2026-27?

The Department’s notified table lists 384 as the cost inflation index for financial year 2026-27. A resident individual selling a house acquired in 2013-14 would then index ₹23 lakh as ₹23,00,000 × 384 / 220, which is a higher indexed cost than the 376 used for a December 2025 sale, and the dual 12.5% versus 20% comparison would be run again with that year’s index.
