Yes, unless you fall inside the tolerance band or get the value reduced. Section 50C deems the stamp duty value to be the full value of consideration for land or building, but only where the stamp duty value exceeds 110% of the actual consideration — that band was 105% for AY 2019-20 and 2020-21 and has been 110% from AY 2021-22.
Section 50C applies to a transfer of a capital asset being land or building or both. Where the consideration is less than the value adopted, assessed or assessable by the stamp valuation authority, "the value so adopted or assessed or assessable shall ... be deemed to be the full value" of consideration for computing capital gains under s.48.
The tolerance band is the first thing to check. The Finance Act 2018 inserted a proviso from AY 2019-20 saying that if the stamp duty value does not exceed 105% of the consideration, the consideration stands. The Finance Act 2020 raised that to 110% with effect from AY 2021-22. So a 9% gap costs you nothing; an 11% gap brings the whole stamp duty value in, not just the excess.
The second check is which date's stamp duty value applies. Where the date of the agreement and the date of registration differ, the first proviso lets you use the stamp duty value on the date of the agreement. But the second proviso makes that available only where the consideration, or part of it, was received by account payee cheque, account payee bank draft, electronic clearing system or another prescribed electronic mode on or before the date of the agreement. Cash advances forfeit the benefit.
The third route is the DVO. Under s.50C(2), if you claim before the Assessing Officer that the stamp duty value exceeds the fair market value on the date of transfer, and you have not disputed that value in appeal or revision elsewhere, the Assessing Officer may refer the valuation to a Valuation Officer. Section 50C(3) contains the safety catch: if the Valuation Officer comes back higher than the stamp duty value, the stamp duty value is used, not his figure. So a reference can only help you.
Section 50C does not tax the difference as a separate head of income — it substitutes a figure into the capital gains computation. Your cost, expenses of transfer and the s.54 family reliefs all still operate on the substituted number.
For tax year 2026-27 onwards this becomes s.78 of the Income-tax Act, 2025, which carries the same 110% tolerance and the same Valuation Officer reference, cross-referring to s.269(3) to (8) for valuation procedure. AY 2026-27 and earlier remain on s.50C.
The tolerance band is a cliff, not a slope: cross it and the whole stamp duty value substitutes, which can turn a modest gain into a large one. A DVO reference is essentially free downside protection because s.50C(3) caps the outcome at the stamp duty value. And an unpaid or cash advance can cost you the right to use an older, lower circle rate.
My mortgaged property was auctioned and the department kept what I owed it out of the proceeds. Do I pay capital gains on the whole price or only on what reached me?
We sold the goodwill our own firm built up over the years. It cost us nothing to acquire. Is the price taxable as a capital gain?
Our JDA was never registered and the project collapsed. Am I still taxed on capital gains?
The landlord paid my company to give up its tenancy. Is that taxable, and if it cannot be computed as a capital gain can the officer tax it as a casual receipt instead?
I received bonus shares and later sold my holding. What is the cost of the bonus shares: face value, nil, or something else?
I sold shares well below market value. Can the officer compute my capital gain on the market price instead of the price I actually received?
I sold shares to a company I control for an agreed price and took the company's own shares, at face value, in satisfaction. Can the officer compute my capital gain on what those shares were really worth?
I sold a depreciable asset held for over three years. Can I still claim the capital gains exemption?
