How this calculator works

Estimates the year's tax, subtracts TDS/TCS and, if the balance is ₹10,000 or more, splits it into the four instalments — 15%, 45%, 75% and 100% by 15 June, September, December and March. Presumptive taxpayers pay everything by 15 March.

Worked example

Estimated income ₹18 lakh (business, new regime), TDS ₹30,000: tax ₹1,66,400, balance ₹1,36,400 — pay ₹20,460 by 15 June, ₹40,920 by 15 September, ₹40,920 by 15 December and ₹34,100 by 15 March.

How to read section numbers: s.80C→s.123 means Section 80C of the Income-tax Act, 1961 is now Section 123 of the Income-tax Act, 2025 (in force from 1 April 2026). Returns for FY 2025-26 still use the old numbers; Tax Year 2026-27 onwards uses the new ones. Section Finder
