Advance tax calculator

Advance tax is due once your liability after TDS crosses ₹10,000 — in four instalments through the year, or a single one if you are presumptive under 44AD/44ADA. This works out each instalment and flags the one to pay next.

Your estimate

Total income tax you expect to owe for the year, before TDS.

Tax already collected at source — on salary, interest, contract receipts and the like.

Presumptive taxpayers under 44AD or 44ADA pay the whole amount in a single instalment by 15 March.

Pay ₹42,000 by 15 Sept 2026. Missing an instalment triggers 234C interest at 1% a month on the shortfall; falling short across the year triggers 234B on the balance. Both run whether or not you meant to defer.

This is one estimate, on one day.

Taxlabs keeps your advance-tax number live all year — updated as income and TDS come in, with a reminder before each instalment date rather than a 234C notice after it.

Frequently asked

Who has to pay advance tax?

Anyone whose tax liability after TDS and TCS is ₹10,000 or more in a year — salaried people with side income, freelancers, business owners and investors. Resident senior citizens with no business income are exempt and can pay everything as self-assessment tax at filing.

What are the advance tax due dates for FY 2026–27?

Four cumulative instalments: 15% by 15 June 2026, 45% by 15 September 2026, 75% by 15 December 2026 and 100% by 15 March 2027. Each figure is cumulative, so the amount you actually pay on a date is that percentage of the year’s tax less whatever was already due.

What is the interest under sections 234B and 234C?

234C is charged for deferring an instalment — 1% a month for three months on each of the first three shortfalls, and one month on the last. 234B is charged when less than 90% of the year’s tax is paid by 31 March — 1% a month on the unpaid balance from 1 April until you pay. They can both apply at once.

How does advance tax work under presumptive 44AD/44ADA?

Taxpayers under the presumptive schemes pay the entire advance tax in a single instalment by 15 March, rather than in four. Miss that date and 234B and 234C interest apply on the whole amount.
