How advance tax works. If your tax liability after TDS exceeds ₹10,000 in a year, you must pay it in four instalments: 15% by 15 June, 45% (cumulative) by 15 September, 75% by 15 December and 100% by 15 March. Taxpayers under the presumptive scheme (Sections 44AD / 44ADA) pay 100% in a single instalment by 15 March. Shortfalls attract interest at 1% per month under Sections 234B and 234C. This estimate uses the new regime with the ₹75,000 standard deduction and the ₹60,000 rebate (Section 87A of the 1961 Act; Section 156 of the Income-tax Act, 2025) — Budget 2026 kept slabs, rebate, surcharge and cess unchanged for FY 2026-27, so the liability is the same for both years; only the instalment dates differ. The advance-tax and interest provisions have been renumbered in the Income-tax Act, 2025 but the instalment percentages, dates and 1% interest mechanics are unchanged. Capital gains and other one-off income should be added in the instalment after they arise. This is a guide — confirm with a professional.
