Advance Tax Calculator
Estimate your advance tax for FY 2025-26 and see how much to pay by each quarterly due date (15 Jun, 15 Sep, 15 Dec, 15 Mar).
How is advance tax calculated?
Advance tax is the “pay-as-you-earn” income tax you pay in installments during the year instead of in a lump sum at the end. Any individual whose total tax liability for the year, after reducing TDS and TCS, is ₹10,000 or more must pay advance tax.
The liability is the slab tax on your estimated taxable income (under the new or old regime) plus a 4% Health & Education Cess. From this you subtract the TDS and TCS already deducted to arrive at the advance tax payable. Always confirm the current slabs and your figures on the official Income Tax portal.
The amount is paid across four installments due on 15 June, 15 September, 15 December and 15 March, with cumulative targets of 15%, 45%, 75% and 100% of the total advance tax. Falling short of these targets attracts interest under Sections 234B and 234C on the shortfall.
Frequently asked questions
Who has to pay advance tax?
Anyone whose total income tax liability for the year, after deducting TDS and TCS, is ₹10,000 or more must pay advance tax. Resident senior citizens (60+) with no business income are exempt.
What are the advance tax due dates and percentages?
For individuals, the cumulative targets are 15% by 15 June, 45% by 15 September, 75% by 15 December and 100% by 15 March of the financial year.
What happens if I miss an installment?
If you pay less than the required cumulative amount by a due date, interest at 1% per month is charged under Section 234C on the shortfall for that installment, and Section 234B may also apply if total advance tax paid is under 90% of the liability.
Is advance tax different under the new and old regime?
The due dates and installment percentages are identical. Only the slab tax used to compute the liability differs, because the new and old regimes have different slabs, rates and rebate limits.
Do salaried people have to pay advance tax?
Usually not, because the employer deducts TDS on salary that covers the liability. Advance tax becomes due only when you have other income — such as interest, capital gains, rent or freelance income — on which TDS falls short of ₹10,000.
What happens if I overpay advance tax?
Any excess advance tax paid over your final liability is refunded when you file your income tax return, and the department pays interest under Section 244A on the refund.
Are these slabs current?
This calculator uses the FY 2025-26 (AY 2026-27) slabs for an individual below 60. Tax law changes frequently, so confirm the latest slabs, surcharge and your figures on incometax.gov.in before paying.
