Introducing the Income Tax Calculator — New vs Old Regime

Every year, salaried Indians face the same question: new regime or old? The new Income Tax Calculator answers it by computing both for FY 2025-26 (AY 2026-27) side by side and telling you which one costs less.

What it does

• Both regimes computed at once from your gross income.
• New-regime slabs for FY 2025-26, with the ₹12 lakh rebate and marginal relief.
• Old-regime slabs with your 80C, 80D, and HRA deductions applied.
• Standard deduction (₹75k new / ₹50k old) and 4% cess included.
• A clear recommendation with the rupee amount you’d save.

Why it matters

Since the new regime became the default, the right choice depends entirely on how much you can deduct. With few deductions, the new regime’s lower rates and big rebate usually win — but heavy deductions can still tip the old regime ahead. Getting it wrong can cost tens of thousands of rupees, so seeing both worked out removes the guesswork.

Informational only

This calculator covers the common case and is for general information, not tax advice. It doesn’t model surcharge on very high incomes or special-rate income like capital gains. Confirm your liability with a qualified chartered accountant.
