Advance Tax on Crypto Gains in India: Who Pays by 15 September?

If you booked a profit on Bitcoin, Ethereum or any other token this year, the tax department may already be expecting money from you — not next July when you file your return, but by 15 September. That is the second advance tax instalment date, and it quietly catches thousands of crypto traders every year. Understanding advance tax on crypto gains in India is not optional once your yearly tax bill crosses a small threshold: pay late and the law adds interest at 1% a month, every month, until you clear it.

This guide walks through who actually owes advance tax on virtual digital assets (VDAs), how the 15 September instalment fits into the year, how to estimate what you owe, and how the 1% TDS already deducted on your trades adjusts the final number. It is educational only — treat it as a map, then confirm your exact position with a chartered accountant.

What advance tax on crypto gains in India actually is

Advance tax is simply income tax paid during the financial year in which you earn, instead of in one lump sum after it ends. The tax system calls it “pay as you earn.” Salaried people meet most of this obligation automatically through TDS on their salary. Traders, freelancers and investors with large one-off gains often do not — and crypto profits are a classic example of income that arrives with no employer withholding the tax for you.

Crypto and other VDAs are taxed at a flat rate on your gains, separate from your salary slab, and a small TDS is deducted on transfers. We explain the rate structure in full in our guide to how 30% crypto tax and 1% TDS work; this article assumes you know the rate and focuses only on when and how you must pre-pay it through advance tax.

The core idea: if your total estimated tax for the year (after adjusting TDS already deducted) is more than ₹10,000, you are expected to pay it in instalments across the year, not at filing time. Crypto gains sit right inside this rule, because a single good trade can push your yearly liability well past ₹10,000 on its own.

Getting this foundation right matters more for VDA earners than for almost anyone else, because nothing withholds tax on your gains automatically. If you would rather build that understanding properly than assemble it from scattered videos, a structured cryptocurrency training course covers the trading and the compliance side together.

The advance tax calendar: why 15 September matters

Advance tax is not one payment. For most taxpayers it is spread across four dates in the financial year, and each date has a cumulative target — the percentage of your total advance tax that should already be paid by then. Miss a target and interest starts running on the shortfall.

Here is the schedule for the current tax year, as published in the advance tax rules and widely summarised by ClearTax, Business Today and CAclubindia:

By 15 September you should have paid 45% of your full-year advance tax — cumulatively, not on top of June.

Read the chart carefully: the 45% due by 15 September is total advance tax paid so far, including whatever you paid in June. If you paid nothing in June, you now need to cover the full 45% in one go. There is a small cushion — no interest applies for deferment if you have paid at least 12% by June and 36% by September — but the safe target to aim at is the headline 45%.

Do you even owe it? The ₹10,000 test after TDS credit

Before you scramble to pay, check whether the rule even applies to you this year. Advance tax is triggered only when your estimated total tax for the year, after subtracting TDS already deducted, is more than ₹10,000. If your net liability is below that, you simply settle up when you file your return — no advance tax, no interest.

For crypto traders, the “after TDS” part is the twist. Indian exchanges deduct 1% TDS on your sell-side transfers, and that TDS is a credit against your final tax. So your advance tax is calculated on what is left after that credit. Two traders with the same gain can owe very different advance tax depending on how much TDS was already collected on their activity.

Who is exempt

One clear carve-out: a resident senior citizen (aged 60 or above) with no income from business or profession is not required to pay advance tax at all, even if the liability crosses ₹10,000. They can pay everything at filing time. But note the condition — if that senior citizen runs a business, freelances or trades as a profession, the normal advance tax schedule applies to them like everyone else. For most working-age crypto traders, there is no exemption; the ₹10,000 test is the only gate.

If you are unsure whether your crypto activity counts as “business income” or “capital gains” — a genuinely grey area for frequent traders — this is exactly the point to ask a chartered accountant, because it changes how you report and, in some cases, how the rules bite.

How to estimate your crypto advance tax (an illustrative example)

You cannot pay advance tax without an estimate of your yearly gain, and crypto makes that hard because the year is not over. The practical approach is to add up realised gains so far, make a conservative estimate for the rest of the year, apply the flat VDA rate, then subtract the TDS already deducted. What is left is what the instalment schedule applies to.

Here is a fully illustrative example — the numbers are invented to show the method, not a benchmark for your own trades. Your figures will differ, and you should confirm them with a tax professional.

Illustrative figures only; your gain, TDS and cess will differ. Confirm with a CA. Rate detail: see our crypto tax guide.

Notice the gap the TDS leaves. The 1% TDS took ₹20,000, but the tax on the gain is ₹1,50,000 — because 1% of turnover is almost never the same as 30% of profit. That difference is precisely what advance tax exists to collect during the year. In this illustration, ₹58,500 should already be paid by 15 September to stay on the safe side of the schedule.

The cost of missing 15 September: interest under sections 424 and 425

Advance tax has teeth, and they are made of interest. Under the Income-tax Act, 2025 — the law in force from 1 April 2026 — two provisions matter for shortfalls. Section 425 (which replaced the old Section 234C) charges interest when you defer an instalment, meaning you paid less than the cumulative target on a date like 15 September. Section 424 (replacing the old Section 234B) charges interest when your total advance tax for the year falls short of 90% of the final bill.

The interest rate is 1% per month, and part of a month counts as a whole month. It is not a one-time penalty; it compounds in the sense that it runs for every month the shortfall stays unpaid. On a ₹58,500 gap, 1% a month is roughly ₹585 each month — small at first, but it keeps ticking until you pay, and it applies again under Section 424 if your full-year payment falls short. Paying on or before 15 September is almost always cheaper than explaining the shortfall later.

Mistakes crypto traders make with advance tax

The interest is rarely the real problem. The real problem is a handful of avoidable errors that leave traders under-paid without realising it:

• Assuming the 1% TDS covers everything. As the example showed, TDS on turnover is tiny next to 30% of profit. Leaning on it is the single most common way traders under-pay.
• Ignoring P2P and foreign-exchange trades. Deals done peer-to-peer, on overseas platforms, or wallet-to-wallet often have no Indian TDS deducted at all — so the entire tax on those gains still has to come from your advance tax.
• Forgetting that losses do not soften the bill. VDA losses cannot be set off against other VDA gains or any other income. A losing Ethereum trade will not reduce the tax on a winning Bitcoin trade, so your taxable gain can be higher than your net-in-pocket feeling suggests.
• Under-estimating the year’s gain. Estimate conservatively. It is better to slightly over-pay advance tax (you get it back as a refund) than to under-pay and carry interest.
• Leaving it to filing season. By the time you file, the interest clock has already run for months. The whole point of advance tax is that it is paid during the year.

If mining or staking is part of your income, the treatment has its own wrinkles — we cover them in our explainer on how crypto mining rewards are taxed, and those amounts feed into the same advance tax estimate.

Your 15 September checklist: what to do now

With the deadline a day away, keep it simple. Total your realised VDA gains for the year so far, add a conservative estimate for the months left, and apply the flat 30% to get your gross tax. Subtract the 1% TDS already deducted, and check whether your net figure crosses ₹10,000. If it does, aim to have 45% of that net figure paid by 15 September, using challan ITNS 280 on the income tax portal under the advance tax head.

Then do the one thing this article cannot do for you: run your actual numbers past a chartered accountant, especially if your trading is heavy, spans P2P or foreign platforms, or blurs the line between capital gains and business income. Understanding advance tax on crypto gains in India is well within any serious trader’s reach — but the final call on your figures belongs with a qualified professional.

Frequently Asked Questions

Who has to pay advance tax on crypto gains in India?

Anyone whose estimated total tax for the year, after subtracting TDS already deducted, exceeds ₹10,000. Because crypto is taxed at a flat 30% on gains with no slab benefit, a single sizeable profit can cross that threshold on its own. Resident senior citizens (60+) with no business or professional income are the main exception.

What percentage of advance tax is due by 15 September?

45% of your total advance tax for the year, on a cumulative basis — that is, including anything you paid by the 15 June instalment. The remaining targets are 75% by 15 December and 100% by 15 March. If you paid nothing in June, the full 45% is due now.

Does the 1% TDS on crypto count towards my advance tax?

Yes. The 1% TDS deducted on your VDA transfers is a credit against your final tax, so you calculate advance tax on the liability that remains after that credit. But 1% of transfer value is usually far smaller than 30% of your gain, so TDS rarely covers the whole bill — the balance is what advance tax collects.

What interest do I pay if I miss the 15 September crypto advance tax?

Interest of 1% per month on the shortfall, under sections 425 (deferment of instalments) and 424 (overall shortfall) of the Income-tax Act, 2025 — the successors to the old sections 234C and 234B. Part of a month is treated as a full month, and the interest keeps accruing until the shortfall is cleared.

Can crypto losses reduce my advance tax?

No. Losses on virtual digital assets cannot be set off against other VDA gains or against any other head of income. Each gain is taxed on its own, so your taxable amount — and therefore your advance tax — can be higher than your overall net position feels. This is a common surprise for active traders.
