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.

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.
