How it works

If your tax after TDS is ₹10,000 or more, you pay it in instalments during the year instead of all at once. Paying less, or late, adds interest of 1% a month.

Income-tax Act 2025
Advance tax is now in new sections of the Income-tax Act 2025 (from 1 April 2026). The dates, percentages and interest rates are unchanged.

Tax after TDS = ₹2,00,000 − ₹40,000 = ₹1,60,000.
Pay 15% by 15 June, 45% in total by 15 September, 75% by 15 December and 100% by 15 March.

Pay the 15 June and 15 September instalments on time: that is where most 234C interest comes from.
Pay online with challan ITNS 280, type 100 (advance tax).
If your income turns out higher or lower than planned, adjust the next instalment.

Section 208 (advance tax if tax after TDS is ₹10,000 or more), section 207 (senior citizens without business income exempt) and section 211 (15% by 15 June, 45% by 15 September, 75% by 15 December, 100% by 15 March; presumptive taxpayers under 44AD and 44ADA pay all by 15 March) of the Income-tax Act 1961. Section 234C: simple interest of 1% a month on the shortfall for 3 months on the first three instalments and 1 month on the last; no interest on the first two if at least 12% and 36% were paid by the dates (the shortfall is measured against 15% and 45%). Section 234B: 1% a month or part of a month on the unpaid tax from 1 April after the year to the date of payment, if advance tax paid is under 90% of the tax. The Income-tax Act 2025 carries the same dates and rates in new section numbers from 1 April 2026. Source: Income Tax Department, advance tax and interest guidance.

What are the limits of Advance Tax Calculator?

A simple estimate: it does not reduce interest for capital gains, lottery or dividend income that arrived after a due date, and it ignores rounding of the amount on which interest is charged. Enter your own tax estimate (the Income Tax Calculator can give it). Nothing you enter leaves your device.
