Advance Tax Calculator (FY 2025-26 / AY 2026-27)
If your total tax liability (after TDS) exceeds ₹10,000 in a financial year, you must pay advance tax in quarterly installments. Missing installments attracts 1% monthly interest under Sections 234B and 234C. Use this calculator to find your exact installment amounts and deadlines.
Senior citizens (60+) without business income are completely exempt from advance tax. Presumptive taxpayers (44AD/44ADA) pay in a single installment by 15 March.
How Advance Tax Works
Who Must Pay?
Anyone whose estimated tax liability for the year exceeds ₹10,000 (after TDS credit) must pay advance tax — including salaried employees, freelancers, business owners, and investors with capital gains. Exception: resident senior citizens (age 60+) with no business income are fully exempt under Section 207.
Quarterly Installment Schedule (Normal Taxpayers)
| Due Date | Cumulative % to Pay |
|---|---|
| On or before 15 June 2025 | 15% |
| On or before 15 September 2025 | 45% |
| On or before 15 December 2025 | 75% |
| On or before 15 March 2026 | 100% |
Presumptive Taxpayers (44AD/44ADA)
If you use Section 44AD (business) or 44ADA (professions), you are exempt from the quarterly schedule. Pay 100% of your advance tax in a single installment on or before 15 March 2026.
Interest on Late/Missed Payments
- Section 234B: 1% per month if total advance tax paid by 31 March is less than 90% of your final assessed tax. Runs from 1 April 2026 until you pay.
- Section 234C: 1% per month for 3 months on shortfall in the June/Sept/Dec installments; 1 month on the March installment. Capital gains and lottery winnings that could not be estimated in advance are exempt from 234C.

Frequently Asked Questions
I am a salaried employee. Do I need to pay advance tax?
Salaried employees usually have TDS deducted by their employer, which covers most of their tax liability. You only need to pay advance tax if your tax liability after TDS exceeds ₹10,000. This can happen if you have additional income from interest, capital gains, rental income, or freelancing that is not covered by employer TDS.
I missed the 15 June installment. What happens now?
Section 234C interest applies on the shortfall: 1% per month for 3 months (effectively 3% of the shortfall). You can still pay the catch-up amount in the next installment. The June deadline was 15 June 2025; if you haven't paid, include the outstanding amount in your September 2025 payment.
My income includes capital gains that I only realised in December. Do I owe 234C interest for the earlier installments?
No. Section 234C provides an exemption for income that could not reasonably have been estimated in advance — this explicitly includes capital gains (other than capital gains on which advance tax is required to be paid under Section 111A or 112). If your capital gains were genuinely not foreseeable at the June or September installment dates, you will not attract 234C interest for those installments.
How do I calculate my estimated tax liability for the year?
Use the income tax slab rates applicable for FY 2025-26 on your estimated total income (salary, business income, capital gains, interest, rent, etc.), apply the applicable deductions (Chapter VIA for old regime, or the standard deduction for new regime), and calculate the resulting tax plus 4% health and education cess. This is your estimated annual tax. Subtract TDS expected to be deducted to get your advance tax liability.
I paid more advance tax than I owe. Will I get a refund?
Yes. If your total advance tax payments exceed your final tax liability, the excess is treated as a refund. File your ITR and claim the refund. The Income Tax Department processes refunds after assessment and credits them to your bank account linked to your PAN/Aadhaar.
