In short: Advance tax is income tax paid in four instalments during the year — by 15 Jun, 15 Sep, 15 Dec and 15 Mar — rather than in one lump sum at filing. It is due whenever your net tax liability after TDS exceeds ₹10,000, and the cumulative targets are 15%, 45%, 75% and 100% of that liability.

Quarterly instalment schedule

Quarterly instalment schedule
Due date	Cumulative %	Cumulative payable	Instalment this quarter
15 Jun	15	₹20,280	₹20,280
15 Sep	45	₹60,840	₹40,560
15 Dec	75	₹1,01,400	₹40,560
15 Mar	100	₹1,35,200	₹33,800

Cumulative targets are 15%, 45%, 75% and 100% of net liability; shortfalls attract §234C interest.

Formula

Net liability = Total tax − TDS • instalments = 15% / 45% / 75% / 100% (cumulative)

Total tax: Full-year tax on your chosen regime, incl. §87A rebate and 4% cess
TDS: Tax already deducted at source, which reduces what you pay directly
Net liability: Advance tax payable — only if it is ₹10,000 or more
15/45/75/100%: Cumulative amount due by 15 Jun, 15 Sep, 15 Dec and 15 Mar

Step-by-step calculation

Worked with the default values.

1
Estimated total tax
New regime tax on ₹15,00,000 + 4% cess
= ₹1,35,200
2
Net liability after TDS
₹1,35,200 − ₹0 TDS
= ₹1,35,200
3
Advance tax applies
Net liability ₹1,35,200 ≥ ₹10,000
= Pay in 4 instalments (15/45/75/100%)
4
By 15 Sep (cumulative 45%)
45% × ₹1,35,200
= ₹60,840

How it works

Estimate your total tax for the year on the regime you expect to file under, including the 4% cess.
Subtract the TDS already deducted; if the balance is ₹10,000 or more, advance tax is due.
Pay it in four instalments so that by each due date you have cleared 15%, 45%, 75% and finally 100% of the net liability.

Examples

₹15,00,000 income, New regime, no TDS

Net liability is well above ₹10,000, so you pay ~15% by 15 Jun, reaching 45% by 15 Sep, 75% by 15 Dec and the balance by 15 Mar.

₹12,00,000 salary with ₹1,10,000 TDS already deducted

If TDS covers almost all the tax, the balance may fall below ₹10,000 — no advance tax is due and any small shortfall is paid at filing.

Understanding the Advance Tax Calculator

What advance tax is — and why it exists

The tax system runs on a "pay as you earn" principle. Rather than let the government wait until you file, advance tax makes you settle your income tax in instalments during the year it is earned. For individuals, it kicks in whenever your net tax liability after TDS is ₹10,000 or more. Below that threshold, you simply pay any small balance as self-assessment tax at filing and skip the quarterly routine entirely.

The quarterly schedule

Advance tax follows a fixed, cumulative calendar for individuals:

15 June — at least 15% of the net liability
15 September — at least 45% (cumulative)
15 December — at least 75% (cumulative)
15 March — 100%

Each due date's payment is the cumulative target minus whatever you have already paid. This calculator works out the net liability first — total tax on your chosen regime, including the 4% cess, minus the TDS already deducted — and then splits it across the four dates for you.

Why TDS matters here

Most salaried people never touch advance tax because their employer's TDS already covers their tax. The problem arises with income that carries little or no TDS: capital gains, interest, dividends, rent and freelance or business profits. On those, you must estimate the tax yourself and pay it in advance. That is why the calculator lets you enter TDS already paid — it is subtracted before the ₹10,000 test is applied, so you never pay twice on the same income.

The cost of getting it wrong

Miss the schedule and interest follows. Section 234C charges roughly 1% a month for deferring or short-paying any single instalment; Section 234B charges interest if you pay less than 90% of the total tax by year-end. Neither is punitive, but both are avoidable. The safe habit is to re-estimate your income each quarter, fold in any capital gains or windfalls, and lean slightly toward overpaying early — a refund costs you nothing, whereas interest steadily eats into your money. Used properly, advance tax turns an intimidating annual liability into four manageable, penalty-free payments.

Pros

Spreads a large tax bill across the year instead of one lump sum at filing.
Avoids §234B and §234C interest that accrues on underpaid or deferred tax.
Keeps cash flow predictable for freelancers and business owners.
Payments reflect in Form 26AS, giving a clean, verifiable tax record.
Lets you revise the estimate each quarter as your income firms up.

Cons

Requires forecasting annual income accurately, which is hard early in the year.
Over-estimating locks up cash as a refund until your return is processed.
Under-estimating triggers interest under Sections 234B and 234C.
You must remember and act on four separate due dates through the year.

Tips

1Re-estimate your income each quarter and top up the next instalment if it has risen.
2Add expected capital gains and interest income to avoid a year-end shortfall.
3Pay the 15 March instalment a day or two early to be safe against portal outages.
4Reduce your advance tax by the TDS already reflected in Form 26AS — don't pay twice.
5When in doubt, pay slightly more early; a refund is cheaper than §234B/234C interest.

Frequently asked questions

Everything you need to know about the Advance Tax Calculator.

Who has to pay advance tax?

Any taxpayer — salaried, freelancer, business owner or investor — whose total tax liability for the year, after subtracting TDS, is ₹10,000 or more. Resident senior citizens (60+) with no business income are exempt from advance tax.

What are the advance-tax due dates and percentages?

For individuals the schedule is cumulative: at least 15% by 15 June, 45% by 15 September, 75% by 15 December and 100% by 15 March. Each date's payment is the cumulative target minus what you have already paid.

When is advance tax NOT payable?

If your net tax liability after TDS is below ₹10,000, no advance tax is due — you simply pay any small balance as self-assessment tax when filing your return. Eligible senior citizens without business income are also exempt regardless of the amount.

How does TDS reduce my advance tax?

Advance tax is only on the tax not already collected. Since employers, banks and clients deduct TDS through the year, you subtract that from your total tax first; you pay advance tax only on the remaining net liability.

What happens if I miss an instalment or underpay?

You attract interest under Section 234C for deferring or short-paying any instalment, and under Section 234B if you pay less than 90% of the total by year-end. The interest is roughly 1% per month on the shortfall, so paying on time is cheaper.

How do I actually pay advance tax?

Pay online through the income tax e-filing portal or your bank's net banking using Challan 280 (now the e-Pay Tax service), selecting "Advance Tax (100)" as the payment type. Keep the challan; the credit reflects in your Form 26AS.

Can I revise my estimate during the year?

Yes. Advance tax is based on your own estimate of annual income, which you can revise each quarter as your income becomes clearer. If income rises, pay the extra in the next instalment to minimise §234C interest.

Is advance tax the same as TDS?

No. TDS is deducted by a payer (employer, bank, client) before paying you. Advance tax is paid directly by you on income where little or no TDS applies — such as capital gains, interest, rent or business profits.

Do salaried people need to pay advance tax?

Often not, because salary TDS covers their tax. But if you have significant other income — capital gains, dividends, interest, freelance or rental income — on which TDS is insufficient, the extra tax may cross ₹10,000 and advance tax becomes payable.

What if I pay the whole advance tax by 15 March?

Any tax paid by 31 March still counts as advance tax, but paying the full amount only in the last instalment means you missed the earlier 15/45/75% milestones, so §234C interest applies on the deferred portions. Spreading payments avoids that.
