If your total tax liability for the year is ₹10,000 or more, you must pay advance tax in four instalments — 15% by 15 June, 45% by 15 September, 75% by 15 December and 100% by 15 March. This calculator estimates your tax under the New Regime for FY 2025-26 (AY 2026-27) and splits it into the four instalments.
How it’s calculated
- New Regime slabs (FY 2025-26): up to ₹4L nil, ₹4–8L 5%, ₹8–12L 10%, ₹12–16L 15%, ₹16–20L 20%, ₹20–24L 25%, above ₹24L 30%.
- A Section 87A rebate makes tax nil for total income up to ₹12,00,000 (₹12.75L for salaried after the ₹75,000 standard deduction), with marginal relief just above that.
- Health & Education Cess of 4% is added to the tax.
- Advance tax is payable only if your net liability (after TDS) is ₹10,000 or more. Instalments: 15% (15 Jun), 45% (15 Sep), 75% (15 Dec), 100% (15 Mar).
Frequently asked questions
Who has to pay advance tax?
Anyone whose total tax liability for the year, after TDS, is ₹10,000 or more — including salaried people with other income, freelancers, professionals and businesses. Resident senior citizens with no business income are exempt.
What are the advance tax due dates?
For non-presumptive taxpayers: 15% by 15 June, 45% (cumulative) by 15 September, 75% by 15 December and 100% by 15 March. Presumptive taxpayers under 44AD/44ADA pay 100% by 15 March.
What happens if I miss advance tax?
Interest is charged under Section 234B (for shortfall of 90%) and Section 234C (for deferment of instalments), at 1% per month. Paying on time avoids this interest.
Does this use the old or new regime?
This calculator uses the New Regime for FY 2025-26, which is the default. Old-regime figures differ because of deductions like 80C, 80D and HRA.
