Advance Tax Calculator

Anyone whose total tax liability for the year (after TDS) exceeds ₹10,000 — this typically applies to freelancers, business owners, and those with significant income beyond salary (like capital gains or rental income).

You may be charged interest under Sections 234B and 234C of the Income Tax Act for shortfall or late payment of each installment — this calculator doesn't compute that penalty interest.

Yes — tax already deducted at source (e.g. on salary or interest income) reduces the net advance tax you need to pay directly, which this calculator accounts for.

The schedule is cumulative — 15% of your net tax liability by June 15, a cumulative 45% by September 15, a cumulative 75% by December 15, and the full 100% by March 15. Because the percentages are cumulative, the amount actually due at each date after the first is the top-up needed to reach that cumulative percentage — for example, the September 15 installment shown is 30 percentage points of your total liability (45% minus the 15% already due in June), not 45% of the total.

Yes. Since this calculator uses the same slab-based computation as the Income Tax Calculator, a full Section 87A rebate applies when taxable income doesn't exceed ₹12,00,000 (new regime) or ₹5,00,000 (old regime), which brings total tax — and therefore every installment — down to ₹0. For example, ₹12,75,000 gross income under the new regime (₹12,00,000 taxable after the ₹75,000 standard deduction) produces ₹0 total tax and ₹0 across all four installments.

Under the new regime, Section 87A's marginal relief means the rebate doesn't disappear outright — it phases out gradually. Taxable income of exactly ₹12,00,000 produces ₹0 tax and no advance tax obligation at all. At ₹12,00,001, marginal relief caps the total tax liability at just ₹1.04 (the ₹1 excess over ₹12,00,000, plus 4% cess) — not the full slab tax. At ₹12,10,000 taxable income, tax is capped at ₹10,400 (₹10,000 excess plus cess), split ₹1,560 by June 15, ₹3,120 by September 15, ₹3,120 by December 15, and ₹2,600 by March 15. This continues until slab tax on the full income falls back below the excess over ₹12,00,000 (around ₹12,70,588 taxable income), after which full slab tax applies with no rebate. The old regime's ₹5,00,000 threshold has no marginal relief — there, the rebate is genuinely lost entirely the instant income exceeds it.

No — if TDS already deducted exceeds your total tax liability, net advance tax payable is floored at ₹0 rather than going negative, and every installment shows ₹0. For example, ₹5,00,000 gross income under the new regime with ₹10,00,000 already deducted as TDS still results in ₹0 net advance tax payable, not a negative figure or a refund calculation — this calculator doesn't compute excess-TDS refunds.

No. Like the Income Tax Calculator it's based on, this calculator does not include surcharge, which applies above ₹50 lakh of taxable income. If your taxable income is above that threshold, your actual advance tax liability — and each installment — will be higher than shown here; consult a tax professional for the surcharge-adjusted figure.
