Nobody Pays 12.5%. Here Is What You Actually Pay.

Ask anyone what they will pay when they sell a mutual fund and you get a number back: 12.5%.

It is the most quoted figure in Indian personal finance right now, and it is almost always wrong. Not because the rate is wrong — 12.5% is exactly what the statute says. It is wrong because a rate is not a bill.

Here is the actual arithmetic on a long-term equity fund gain, at three sizes.

Same fund. Same rate in the statute. Three different tax rates, none of them 12.5%.

There is exactly one long-term equity gain in the whole of India on which you pay 12.5% and not a paisa more or less. It is ₹32,50,000 — the ₹1.25 lakh exemption pulling the rate down, the 4% cess pushing it up, and the two cancelling out at precisely that number. Everybody below it pays less than 12.5%. Everybody above it pays more.

Those three figures assume your total income stays under ₹50 lakh, which is where surcharge starts. Above that line every number on this page moves up, and the receipt further down lets you switch it on.

And that is the easy bucket. It assumes you hold an equity fund, that you held it long enough, and that the exemption was still available to you. Change any one of those and the number moves again. Hold a debt fund and 12.5% may not enter the calculation at all — you could be paying 31.2%.

This is not a rate. It is a sequence.

Your redemption is not taxed at a rate. It is taxed by four questions, asked in a fixed order by the Income-tax Act, 2025. Answer them in order and the rate falls out at the end. Get one of them wrong and you can be out by a factor of two on the very same fund.

So this is not an essay with a table at the bottom. It is the four questions, in the Act's own order, each with a control you can move. Your answers follow you down the page and print an itemised receipt at the end.

That strip is live. Every control below writes into it.

Question 1 — What did you actually buy?

Most people believe there are two kinds of mutual fund: equity and debt. The Act recognises four, and knowing which one you are in is worth more than most fund selection decisions you will make this year.

The dividing lines are percentages inside the portfolio, not the name on the scheme.

Two of those deserve a warning label.

Bucket 3 is defined by what the fund holds, not by what you think it is. Up to FY 2024-25 the test was equity exposure — a fund with 35% or less in domestic equity was caught. From FY 2025-26 the test flipped to debt exposure: more than 65% in debt and money market instruments, measured on the annual average of daily closing figures. That single rewrite quietly evicted a large group of funds from the harshest treatment in the Act.

The date is worth pinning down, because the amendment reads with effect from 1 April 2026 and that is assessment-year language. Assessment year 2026-27 is the year in which you file for money earned in financial year 2025-26. So the new test has governed redemptions since 1 April 2025 — including any you are reporting in this filing season.

Bucket 4 barely existed before that rewrite, and a lot of people are standing in it without knowing. A fund with less than 65% in listed domestic equity and less than 65% in debt is in none of the first three. Gold and silver ETFs. Gold and silver fund-of-funds. International equity ETFs and fund-of-funds. Multi-asset funds that hold under 65% in domestic equity — and note that many multi-asset funds deliberately hold above 65% precisely so they land in bucket 1, so this one you have to check rather than assume. Under the old test all of them were treated as debt and taxed at slab rates however long you held them. They have not been since FY 2025-26.

Here is how much money that is, from AMFI's July 2026 report.

A crore and a quarter of gold ETF folios changed tax bucket last year, and it was barely reported.

Question 2 — When did you buy it?

For three of the four buckets the answer is it does not matter. For bucket 3 it is the single most valuable fact about your holding.

Units of a specified mutual fund acquired on or after 1 April 2023 produce short-term capital gains when you redeem, and that is true irrespective of how long you held them. Not one year. Not ten. There is no long-term treatment available at all, and no indexation to soften it — the Act now computes long-term gains without indexation in every bucket, so there is nothing left to fall back on.

Units acquired before that date kept the ordinary treatment.

The result is a cliff with a one-day drop. Same scheme, same amount, same gain, same holding period — two purchase dates twenty-four hours apart.

That gap is not a penalty for doing anything wrong. It is a date.

Which leads to the practical point almost nobody acts on. If you still hold debt fund units bought before April 2023, they are a materially better asset than the units you bought last year, and they are sitting in the same folio. Redemptions run first-in-first-out, so those old units leave first by default. That is worth knowing before you place the order, not after.

Question 3 — How long did you hold it?

Only now does holding period enter, and only for the buckets where question 2 left it alive.

There are two thresholds in the Act, and which one applies depends on whether the thing you own is listed.

• Units of an equity-oriented fund: 12 months. Above it, long-term. At or below it, short-term at a flat 20%.
• Anything else that is listed — a gold ETF, a silver ETF, an international ETF: 12 months.
• Anything else that is not listed — a gold fund-of-fund, an international fund-of-fund, a scheme you bought from the AMC: 24 months.

That last line catches people. A gold ETF bought on the exchange and a gold fund-of-fund that holds the very same ETF are the same exposure to the same metal, and they cross into long-term treatment a full year apart.

Move the dial and watch what your all-in rate does as the months run.

If you picked a debt fund bought after April 2023, that chart is a flat line. There is nothing to wait for. That is the entire design of the provision.

Question 4 — What else did you earn this year?

The first three questions decided which rate. This one decides how much of it you actually pay, and it is where the headline number finally comes apart.

Four things ride on it.

The slab. For a bucket 3 fund, and for anything short-term in bucket 4, there is no special rate at all. The gain is added to your income and taxed at whatever your top slab is — 5%, 10%, 15%, 20%, 25% or 30% under the default new regime. A gain that pushes you into the next slab is taxed at the higher one.

The ₹1.25 lakh exemption. Long-term gains on equity-oriented funds are exempt up to ₹1,25,000 a year. Not per scheme, not per folio, not per redemption — one aggregate allowance covering every listed share and every equity fund unit you sell in that financial year. It resets on 1 April and it does not carry forward. An allowance you did not use is simply gone.

Surcharge. It starts above ₹50 lakh of income, and here the buckets part company again. On short-term gains from an equity fund and on every long-term gain — sections 196, 197 and 198 — surcharge is capped at 15% however high your income goes. But a bucket 3 gain, and a short-term bucket 4 gain, are not special-rate income at all. They are ordinary income, they stack on your salary, and they take the ordinary surcharge, which runs to 25% under the default new regime and 37% if you are still on the old one. The cap that shelters an equity investor does not shelter a debt fund investor.

Cess. 4% on top of tax plus surcharge, always, with no threshold. This is the piece everyone drops. It is why 12.5% is really 13%, 20% is really 20.8%, and a 30% slab is really 31.2%.

There is also a quiet kindness in the Act worth knowing: if you are a resident individual and your other income falls below the basic exemption limit, the shortfall is set against your capital gains before they are taxed. A retired parent with ₹2 lakh of interest income and a ₹4 lakh gain does not pay tax on the whole ₹4 lakh. It is one of the few provisions that reliably works in a small investor's favour, and it is why redeeming in a low-income family member's name is a legitimate planning decision rather than a trick.

Put the exemption and the cess together and the headline rate stops being a rate. It becomes a curve.

For an equity fund held long enough, the curve starts at zero, climbs steeply through the small gains, crosses the famous 12.5% at ₹32,50,000, and then keeps climbing slowly toward 13% — the rate plus cess, before any surcharge — and never quite arrives. Switch surcharge on in the receipt below and the whole curve lifts, along with the point where it crosses 12.5%. For a debt fund bought after April 2023 there is no curve at all. It is a horizontal line at your slab plus cess, from the first rupee of gain to the last.

The receipt

Everything above resolves into one piece of paper. This is your four answers, priced.

Change anything you like — the file at the top of the article and this receipt read the same state.

Two lines on that receipt do most of the damage in real portfolios: the exemption you did not use, and the slab that applied because a fund was in a bucket you did not know about.

What a debt fund actually keeps

Now the part that nobody puts in a tax article, because it turns a tidy topic into an uncomfortable one.

A tax rate is a share of the gain, not a share of the money. So the same rate hurts very differently depending on how much the asset earned in the first place. Twelve and a half per cent of a 10% return costs you 1.3 percentage points. Thirty-one point two per cent of a 5.7% return costs you 1.8 — more, in absolute terms, out of a return that was less than half the size.

And then inflation takes its cut, from the whole thing, before you have kept anything at all.

Here is that arithmetic run on NSE's own Fixed Income Index Dashboard for 31 July 2026 and MoSPI's July 2026 CPI print of 4.45%.

Read that at a 30% slab and the message is blunt. Over the five years to 31 July 2026, most of the Indian debt fund universe returned somewhere between 5.3% and 7.3% a year. Take 31.2% off in tax and 4.45% off in inflation and what remains is a number hovering around zero — slightly negative for the longer-duration indices, slightly positive for credit risk, and essentially a rounding error either way.

Three things need saying about that, because a chart like this is easy to misuse.

First, the window was a bad one for bonds and I have not hidden it. The five years to July 2026 contain a full rate-hike cycle, and rising rates mark bond prices down. The NIFTY Long Duration Debt Index returned −0.06% over the last twelve months alone. Flip the toggle to what they yield today and the picture improves across the board, because a bond fund's yield is a far better forecast of its future return than its past five years are.

Second, this is not an argument against debt funds. It is an argument against expecting the wrong thing from them. Nobody should be holding a liquid fund in order to get rich; they hold it so that ₹8 lakh is definitely there in March when the school fee and the advance tax land in the same week. Certainty and immediate access are the product. A real return near zero is the price of that product, and it is a fair price. The mistake is not owning debt funds — it is owning them for a decade in the belief that they are quietly compounding.

Third, the tax is doing more damage here than in equity, and it is worth being precise about why. It is not that the rate is higher in some abstract sense. It is that the rate applies to a smaller return, so it takes a bigger bite of a thinner slice, and there is no ₹1.25 lakh shelter underneath it to absorb the first part.

Four things this changes on Monday

Use the ₹1.25 lakh before March, not the ₹1.25 lakh in your head. It resets every 1 April and it does not carry forward. If you hold equity funds with unrealised long-term gains and you have not used the allowance this year, redeeming enough to realise about ₹1.25 lakh of gain and reinvesting costs you nothing in tax and permanently raises your cost base. Do it in a fund you intend to keep owning, mind the exit load and any lock-in, and remember the allowance is shared with any listed shares you sold.

Find out which bucket each of your funds is in — before you place the redemption, not after. Especially your gold, silver, international and multi-asset holdings. The rules changed under them in FY 2025-26, and in almost every case the change went your way. If you redeemed any of those during FY 2025-26, that is the year you are filing for now — check the treatment before the return goes in, not after.

Look at your debt fund purchase dates. Units bought before April 2023 are taxed at 12.5%; units bought after are taxed at your slab. They live in one folio and the older ones go out first. That is a real decision, not a technicality.

Match the fund to the horizon and the bucket at the same time. A goal eighteen months away in a gold fund-of-fund is a slab-rate redemption; the same money in a gold ETF is 12.5%. A three-year goal in a debt fund bought last year earns you nothing for the wait. These are not clever tricks — they are the difference between a plan built around the tax code and a plan that collides with it.

The honest summary

The 12.5% everybody quotes is real. It is just not a rate anybody pays, except by coincidence at a gain of ₹32,50,000.

What you actually pay is the output of four questions — what the fund holds, when you bought it, how long you held it, and what else you earned that year — and every one of them can move your bill more than a good year of fund performance would.

None of that is a reason to invest around the tax code. Tax follows returns; it does not lead them. But the same money, in the same fund, redeemed with the four answers in hand instead of guessed at, is worth measurably more. That is about as close to free as investing gets.
