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.

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.

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.
