Advance Tax — Due Dates, Calculation & Interest for Default

Advance Tax — Complete Guide

If your total tax liability for the year exceeds ₹10,000 (after TDS), the law expects you to pay tax in instalments as you earn, not in one lump sum after the year ends. This is advance tax — and missing it triggers meaningful interest costs.

Who Must Pay It

Any taxpayer — salaried, self-employed, or investor — whose total tax liability (after subtracting TDS/TCS already deducted) exceeds ₹10,000 for the year. Salaried employees often don’t need to worry about this separately since their employer’s TDS typically covers most of their liability — but those with significant capital gains, rental income, freelance income, or interest income frequently do need to pay advance tax on top of TDS.

The Standard Quarterly Schedule

Presumptive Taxpayers Get a Simplified Schedule

Those under Section 44AD or 44ADA presumptive taxation can pay their entire advance tax in a single instalment by 15th March, instead of the four-instalment schedule — a genuine cash-flow benefit recognising the difficulty of estimating presumptive income early in the year.

Interest for Non-Payment or Short Payment

The Capital Gains / Windfall Income Relief

If you receive income that couldn’t reasonably have been anticipated earlier in the year (like a large, unexpected capital gain or lottery winning), Section 234C interest generally doesn’t apply for the earlier instalments — but you must pay the tax on that income in the immediately following instalment to avoid interest from that point forward.

Example

An individual sells a property in January, realising a large capital gain. Since this couldn’t have been anticipated for the June, September, or December instalments, no 234C interest applies for those. But they must include the resulting tax liability in their 15th March instalment — missing that would trigger interest going forward.

Worked Example

An individual’s total estimated tax for the year is ₹2,00,000, with ₹80,000 already covered by TDS. Advance tax liability: ₹1,20,000. They should pay: - By 15th June: 15% of ₹2,00,000 = ₹30,000 (but only ₹1,20,000 total is due through advance tax, since ₹80,000 is TDS — payment should be calculated on the net advance tax liability using cumulative percentages) - By 15th September: cumulative 45% - By 15th December: cumulative 75% - By 15th March: cumulative 100%

Frequently Asked Questions

Q1. Do I need to pay advance tax if all my income is from salary with proper TDS deducted? Generally no — if your employer’s TDS adequately covers your tax liability, you typically don’t have a separate advance tax obligation, unless you have other significant income (capital gains, rental, freelance) not covered by TDS.

Q2. What happens if I pay my entire advance tax late, in one go, after 15th March? You’ll owe interest under both Section 234B (for the annual shortfall) and Section 234C (for each missed instalment) — paying late doesn’t just delay the payment, it compounds the interest cost across multiple provisions.

Q3. Can I estimate my advance tax and adjust it in later instalments if my income changes? Yes — advance tax is based on your own reasonable estimate of annual income, and you can revise your estimate and adjust subsequent instalment payments as your actual income becomes clearer through the year.
