Old vs New Regime — Free Advance Tax Calculator 2026-27

The CalcGuru Advance Tax Calculator works out how much advance tax you must pay for FY 2026-27 (AY 2027-28) and splits it across the four instalment due dates — 15 June, 15 September, 15 December and 15 March — along with any Section 234B and 234C interest. It covers salary, house property, business and professional income, capital gains (shares, property, gold, crypto), dividends and winnings, for individuals, senior citizens, firms / LLPs and companies, under both the old and new tax regimes.

How to use it: choose what you are calculating from the dropdown, pick your tax regime, enter your estimated income (and any capital gains with the quarter they arose), add TDS or advance tax already paid, and the panel on the right instantly shows your total tax, the instalment-wise schedule and any interest payable.
