Income Tax Calculator India FY 2025-26 — New vs Old

This income tax calculator for India applies the FY 2025-26 (AY 2026-27) slabs introduced by the Finance Act 2025 — and since Budget 2026 left the slabs unchanged, the same numbers hold for FY 2026-27. Enter your annual income and it computes both regimes side by side: the new regime with its ₹75,000 standard deduction and seven slabs (nil up to ₹4 lakh, then 5%, 10%, 15%, 20% and 25% bands up to ₹24 lakh, and 30% above), and the old regime with its ₹50,000 standard deduction, classic 5%/20%/30% slabs and a field for your 80C, 80D and HRA deductions. It highlights which regime is cheaper and by exactly how much.

The calculation follows the Income Tax Act's method precisely. Under the new regime, the Section 87A rebate wipes out tax entirely when taxable income is up to ₹12 lakh — about ₹12.75 lakh of salary after the standard deduction — with marginal relief so incomes just above the limit are never worse off. A worked example: on a ₹16 lakh salary, taxable income is ₹15.25 lakh; slab tax comes to ₹20,000 + ₹40,000 + ₹48,750 = ₹1,08,750, plus 4% health and education cess of ₹4,350 — ₹1,13,100 in total, alongside your take-home and effective rate.

Everything runs in your browser: your salary is never uploaded or stored, so it is safe to test a real offer letter or the raise you are negotiating. Treat the result as a close planning estimate — it deliberately excludes the surcharge on very high incomes and assumes resident, under-60 old-regime slabs, so confirm final figures with a tax professional before filing.
