Advance Tax Calculator FY 2025-26 — Quarterly Instalment Schedule

Advance tax is a pay-as-you-earn mechanism under the Income Tax Act. If your estimated net tax liability (total tax minus TDS deducted) exceeds ₹10,000 for the financial year, you are required to pay tax in quarterly instalments rather than waiting until the return filing date. Failure to pay advance tax on time attracts interest under Section 234B (for aggregate shortfall below 90%) and Section 234C (for each deferred quarterly instalment). This calculator estimates your total tax liability under both old and new tax regimes, then breaks it into the four instalment payments due on 15 June, 15 September, 15 December, and 15 March. Use it to advise your clients early — especially those with business income, capital gains, or freelance income where TDS does not cover the full liability.

Frequently Asked Questions

Who is required to pay advance tax?+
Any taxpayer whose total tax liability (after TDS) exceeds ₹10,000 for the year must pay advance tax in instalments. This applies to salaried, business, professional, and capital gain income. Senior citizens (60+) with no business income are exempt from advance tax.
What are the advance tax due dates for FY 2025-26?+
For non-corporate assessees: 15 June (15%), 15 September (45%), 15 December (75%), 15 March (100%). For corporate assessees: 15 June (25%), 15 September (50%), 15 December (75%), 15 March (100%).
What happens if advance tax is not paid on time?+
Non-payment or short-payment of advance tax attracts interest under Section 234B (1% per month on shortfall below 90% of final tax) and Section 234C (1% per month for each quarter's deferment). These interests are calculated at the time of filing the return.
Can advance tax be paid in lump sum?+
Yes, you can pay the full advance tax in a single payment before 15 March. However, to avoid Section 234C interest for each quarter, at least 15%, 45%, and 75% must have been paid by June 15, September 15, and December 15 respectively.
How is advance tax calculated for freelancers and consultants?+
For freelancers under Presumptive Taxation (Section 44ADA — 50% of gross receipts), the entire advance tax can be paid in a single instalment on or before 15 March. This is a special relaxation for professionals under the presumptive scheme.
