Section 78, Income-tax Act 2025: Special provision for full value of consideration in certain cases

What changed when Section 50C became Section 78?

The number moved; the rule did not. Section 50C of the Income-tax Act 1961 became Section 78 of the Income-tax Act 2025, keeping the same title, "Special provision for full value of consideration in certain cases". The stamp-value substitution, the 10% tolerance band, the agreement-date rule and the Valuation Officer reference all carry across intact. From TY 2026-27 your capital-gains working cites Section 78 where it used to cite 50C.

One cross-reference is worth learning. The deemed value that Section 78 produces is not the tax by itself; it is the sale figure that feeds the capital-gains computation in Section 72 (the old Section 48). Section 72 then subtracts your cost of acquisition, cost of improvement and expenses of transfer to arrive at the gain. So Section 78 changes one input, the sale value, and the rest of the sum runs as normal.

When does the stamp duty value replace your sale price?

Whenever you sell land, a building, or both held as a capital asset for less than the stamp duty value, and the gap is more than 10%. The stamp duty value is the benchmark the state stamp-valuation authority adopts or assesses for charging stamp duty on the transfer, the figure most people call the circle rate, guideline value or ready-reckoner rate. If your actual price is below it beyond the tolerance, Section 78 deems the whole stamp value, not just the excess, to be your sale price.

The point of the rule is to close an old gap. Property was routinely registered at a fraction of its real price, with the balance paid in cash, which shrank the seller's capital gain and hid unaccounted money. By anchoring the taxable sale value to the state's own stamp-duty benchmark, Section 78 makes the on-paper price hard to understate.

It bites even when the low price is genuine. If you sold in a hurry, to a relative, or in a soft market where the circle rate has not caught up with reality, the section still applies unless you use the Valuation Officer route below. The tax is on a deemed figure, so you can owe tax on a gain larger than the cash you actually took home.

How the 10% tolerance band works

A 10% cushion keeps small, honest gaps out of the net. If the stamp duty value is no more than 110% of the price you actually received, Section 78 steps aside and your price stands as the sale value. Cross that line by a rupee and the entire stamp value becomes your deemed sale price, not merely the part above 110%.

The band started smaller: it was introduced at 5% and later widened to 10%, and the wider band matters because circle rates are often stale and sit above real transaction prices in many areas. A ₹1 crore flat with a stamp value of ₹1.08 crore is inside the band and taxed on ₹1 crore; the same flat with a stamp value of ₹1.12 crore is outside it and taxed on the full ₹1.12 crore.

The tolerance is a cliff, not a graduated allowance. Once the stamp value tops 110% of the price, the whole stamp value applies, so a sale priced just under the band edge is worth getting right.

Who and what Section 78 covers

The section is about one kind of asset in the seller's hands, and it has three siblings that catch the cases it does not:

• It covers a transfer of land or a building, or both, held as a capital asset: an investment plot, a house, a shop or an office you held as an investment. Section 78 is a computation rule, so it applies to every such seller, resident or non-resident.
• It does not cover property held as stock-in-trade. A builder or trader whose flats and plots are inventory is dealt with by Section 53 (the old Section 43CA), which does the same stamp-value job on the business-income side.†
• It does not cover unquoted shares or other assets. Selling unlisted shares below fair value is Section 79 (old 50CA); an asset whose consideration cannot be determined at all is valued under Section 80 (old 50D).†
• It reaches unregistered transfers too. Where a deal is not registered, the value the authority would have assessed had it gone for stamp duty is used: the Act-wide definition of stamp duty value in Section 2 covers the value "adopted or assessed or assessable", so skipping registration does not dodge the rule.

Rights in property such as tenancy or development rights have generated litigation on where the line falls; a valuer's view helps in borderline cases.

What are the main rules of Section 78?

The stamp duty value is the state authority's figure; the "assessable" limb of the stamp-duty-value definition in Section 2 extends it to transfers that were never registered.†

The agreement-date rule: locking in an earlier stamp value

Property deals often fix a price long before the sale deed is registered, and circle rates can climb in between. Section 78(1)(a) lets you use the stamp duty value on the date of the agreement, rather than the higher value on the date of registration, but only if two conditions are met.

Both of these must hold:

• The date of the agreement that fixed the price is different from the date of registration.
• Some or all of the consideration was received on or before the agreement date through a banking or online channel: an account-payee cheque, an account-payee bank draft, electronic clearing through a bank account, or another notified electronic mode. A cash advance does not count.

A cash token, however small, fails the condition and throws you onto the registration-date stamp value. Take even a small advance by cheque or bank transfer on the agreement date, and the earlier value is locked in, as the third worked example shows.

Disputing the stamp value: the Valuation Officer reference

You are not stuck with a stamp value that is plainly too high. Under Section 78(2), if you claim the stamp duty value exceeds the property's fair market value on the date of transfer, and you have not separately disputed that stamp value in an appeal, a revision, or before any other authority or court, the Assessing Officer may refer the valuation to a departmental Valuation Officer.

The route is deliberately one-sided in your favour. If the Valuation Officer's figure comes in below the stamp value, that lower figure becomes your sale value. If it comes in above the stamp value, Section 78(3) ignores the excess and caps your sale value at the stamp value. Asking for the reference can only reduce your taxable figure or leave it unchanged; it can never push it higher, which is why raising the fair-market-value objection carries no downside on the value itself.

Bring evidence: a registered valuer's report, comparable sale instances, and anything showing the property's defects or the reasons for the low price. The Valuation Officer weighs the same factors a buyer would.

How to calculate your capital gain under Section 78

Five steps, once you know your price and the stamp value:

• Take your actual sale consideration and the stamp duty value for the property. Use the agreement-date stamp value if you meet the banking-mode condition above, otherwise the value on the registration date.
• Apply the 10% test: if the stamp value is no more than 110% of your price, use your actual price as the sale value and move to the cost step. If it is more than 110%, your sale value is the full stamp value.
• If the stamp value looks inflated, decide whether to ask for a Valuation Officer reference before accepting it.
• Subtract your cost of acquisition, any cost of improvement and the expenses of transfer (brokerage, legal fees) from the sale value, under Section 72. For a long-held property this is where indexation, where still available, or the flat long-term rate applies.
• The result is your capital gain. Land or a building held for more than 24 months is a long-term asset, taxed at the long-term rate; 24 months or less makes it short-term, taxed at your slab.

The deemed value changes only the sale figure. Every cost and exemption you were entitled to still applies to the computation that follows; whether a Section 54 or 54F reinvestment exemption is measured on the actual or the deemed value has been litigated.†

Is the buyer taxed when you sell below stamp value?

Often, yes, and it is taxed a second time. If someone buys land or a building for less than its stamp duty value, the shortfall is treated as the buyer's income under the head income from other sources, the rule carried over from the old Section 56(2)(x). So one under-priced deal can be taxed on both sides of the table: a larger capital gain for you, and other income for the buyer.

The buyer's rule has its own cushions. The shortfall is taxed only when the stamp value exceeds the price by more than the higher of ₹50,000 and 10% of the price; when it does, the entire shortfall, stamp value minus price, is the taxable income. The same agreement-date and banking-mode relief applies, so a cheque advance protects the buyer just as it protects the seller.

Gifts and transfers between specified close relatives are outside the buyer-side charge, which is why an intra-family transfer at a low price is not automatically taxed in the recipient's hands.†

How does Section 78 affect the 1% property TDS?

There is a third figure in the same transaction, and it also keys off the stamp value. When residential or commercial property (not rural agricultural land) sells for ₹50 lakh or more, the buyer must deduct 1% TDS and pay it to the government, the rule known as Section 194-IA, now folded into the TDS table of Section 393 of the 2025 Act.†

The base for that 1% is the higher of the sale consideration and the stamp duty value. So the same understated price that triggers Section 78 for the seller also raises the buyer's TDS: on a flat priced at ₹80 lakh with a stamp value of ₹95 lakh, the 1% is charged on ₹95 lakh, which is ₹95,000, not ₹80,000. A separate change from 1 October 2024 counts all buyers and sellers together, so splitting a ₹90 lakh deal into two ₹45 lakh shares no longer ducks the ₹50 lakh threshold.

The 1% is not a separate tax. The seller claims it back as tax already paid when filing, and any excess over the final capital-gains tax is refunded.

Traps and edge cases

Where Section 78 catches people out:

• Tax on cash you never saw. Once you cross the 10% band the deemed value is the whole stamp value, so a genuine below-market sale can leave you taxed on a gain larger than the money you received. The Valuation Officer route is the only relief, and it needs evidence.
• The wrong stamp value. Without a banking-mode advance, the value on the registration date applies, even if you fixed the price years earlier at a lower circle rate. Take a cheque advance on the agreement date to lock the earlier figure.
• The band is a cliff. At exactly 110% of the price the sale value is still your price; a rupee more and the entire stamp value applies. A sale priced just under the edge is worth pricing carefully.
• Both sides are taxed. Under-pricing to help a buyer can cost the buyer an income-tax bill on the discount, on top of your own higher capital gain.
• Joint owners. The band and the stamp value apply to the property and the transaction, then the deemed gain is split among co-owners in their shares; the band is not multiplied per owner.

What to do before you sell below the circle rate

Check the stamp duty value before you sign anything. Every state publishes its circle rate, guideline value or ready-reckoner rate online and at the sub-registrar's office, and your sale value for tax cannot fall more than 10% below it without consequences. If your buyer's best offer is more than 10% under the circle rate, you are choosing to be taxed on income you will not receive, so price the deal knowing that.

Keep the gap inside 10% where you can. On a plot whose circle rate is ₹1 crore, a sale at ₹91 lakh or above stays inside the band and is taxed on the actual price; a sale at ₹88 lakh is taxed on the full ₹1 crore, adding ₹12 lakh of deemed gain and, at the 12.5% long-term rate, about ₹1.5 lakh of extra tax before cess for no extra cash in hand.

If the circle rate is genuinely above market, gather your proof before filing: a registered valuer's report, comparable sales, photographs of defects, and the reasons for a distress sale. Then ask the Assessing Officer for the Valuation Officer reference, which can only bring your figure down.

And if a price is fixed now for a later registration, take a token advance by cheque or bank transfer on the agreement date. It costs nothing and freezes the stamp value at today's figure, which in a rising market is often the single biggest saving on the whole deal.
