Advance Tax Calculator, FY 2026-27
Enter your income for the year to see what you owe, when each instalment falls due, and what a missed deadline costs under sections 424 and 425 of the Income-tax Act, 2025. Built for the new regime.
Best effort estimate, not tax advice. This is an approximate calculation for a resident individual under the new regime for FY 2026-27. Individual circumstances vary and the rules change, so please check with your chartered accountant before acting on anything here or making a payment.
Income for the full year
Estimate these for the whole year. The law expects you to, so recording when they arrive would not move a single deadline.
Gross, before the 75,000 standard deduction.
Savings, fixed deposits, bonds. Banks deduct TDS at only 10%.
Annual and gross. The 30% statutory deduction is automatic.
Section 80CCD(2). The one deduction the new regime allows.
Gains and dividends
The only income the section 425 timing relief covers, so when you booked it changes what you owed at each deadline.
A single yearly figure. The tax on it is spread across all four deadlines from June.
Held under a year. Taxed at 20% under section 111A.
Held over a year. First 1,25,000 exempt, rest at 12.5%.
From shares and mutual funds. Taxed at your slab rate.
TDS already deducted
What your employer, bank and tenant take at source before you ever see the money. Advance tax is only the gap this leaves.

Change a rate if yours differs. Interest is deducted at 20% where the bank has no PAN on file, and rent paid by an individual tenant is 2% under section 194-IB rather than the 10% a business deducts. Thresholds still apply at any rate, and they run per bank and per company, so spreading money across several means less deducted here and more advance tax to pay.

India runs on pay as you earn. If your tax for the year comes to 10,000 rupees or more after TDS and TCS, the law does not wait until you file. It wants the money in four instalments across the year, and it charges interest on every rupee that arrives late.
Salaried people assume TDS covers everything. It usually does not. Your employer only deducts against salary. A bank deducts just 10% on fixed deposit interest when your slab rate might be 30%, and it deducts nothing at all on capital gains. Those gaps are what turn into an interest bill in July.
New from FY 2026-27
The Income-tax Act, 2025 has replaced the 1961 Act. The interest sections are renumbered: 234A is now 423, 234B is now 424, and 234C is now 425.
The rules themselves are unchanged, so older guides are still correct on substance even where the numbers have moved.
Section 425, old 234C, for missing a deadline
1% a month on whatever you were short at each due date, for three months on the first three instalments and one month on the last. It is capped and predictable. Miss every deadline on a 1,00,000 rupee liability and it comes to about 5,050 rupees.
Section 424, old 234B, for ending the year short
This is the expensive one. If you have paid under 90% of your tax by 31 March, 1% a month runs on the whole shortfall from 1 April until you actually pay. It does not stop at the year end, so the longer you take to file, the larger it grows.
The relief most people miss
Pay at least 12% by 15 June and 36% by 15 September and no section 425 interest arises for those instalments, even though the schedule asks for 15% and 45%. Estimating a little low early in the year is forgiven. Paying nothing is not.
Filing the return itself late adds section 423, old 234A, at a further 1% a month. This tool assumes you file on time.
Capital gains get a pass on timing
You cannot forecast a gain you have not booked. Where a shortfall arises because of capital gains, dividends or lottery winnings, no section 425 interest applies as long as you pay the tax on that income in the instalment right after you receive it, or by 31 March if it lands in the final quarter. Book a large gain in December and pay by 15 March and you are clear.
Switch the input above to By date booked to use this. An annual figure has to assume the gain was there from April, which overstates what you owed at the earlier deadlines. Note that the relief is timing, not exemption: the tax still has to be paid before 31 March or section 424 picks it up.
Who is exempt
A resident aged 60 or above with no business or professional income does not pay advance tax at all under section 207, no matter how large the liability. Pension and interest income alone will not pull a retiree into the schedule. They simply pay self assessment tax before filing.
How to actually pay it
Through the e-Pay Tax section of the income tax portal, choosing minor head 100, advance tax, and the correct assessment year, 2027-28 for FY 2026-27. Picking the wrong minor head is a common and annoying mistake to unwind.

If capital gains are what pushed you into advance tax, it is worth reading how portfolio diversification and knowing when to buy shape when those gains get booked in the first place.
What this does not cover: business or professional income, presumptive taxation under sections 44AD and 44ADA, house property loss set-off, crypto and other virtual digital assets, foreign income and foreign asset reporting, TCS on overseas remittances, and the old tax regime. It assumes you are resident and that you file your return on time, so section 423 interest for late filing never appears.
Interest is computed on the estimate you enter here, while the department computes it on your returned income, so the two will differ if your actual income does. Figures are rounded as the rules require, which can leave small differences against an intimation. See our full disclaimer.
