Income tax calculator
Old vs new regime, side by side — see which one actually saves you money.
Quick answer
An income tax calculator for FY 2025-26 (AY 2026-27) compares tax under India's old and new regimes side by side. The new regime offers lower slabs and ₹75,000 standard deduction; the old regime rewards 80C, HRA, and home-loan deductions.
Old-regime deductions
New regime wins
You save ₹1,11,800 a year by choosing the new regime with these deductions.

Deductions only reduce tax under the old regime. The new regime gives a bigger standard deduction (₹75,000) and lower slabs but ignores 80C, 80D, HRA and the rest.

What this tells you
Every year salaried Indians agonise over the old versus new tax regime. This calculator settles it: enter your income and deductions, and see the tax and take-home under both, side by side.
The new regime is now the default. It has lower slab rates and a ₹75,000 standard deduction, but scraps almost all exemptions. The old regime taxes more but rewards 80C, 80D, HRA and home-loan interest.
How it's calculated
We apply the FY 2025-26 slabs for each regime, the standard deduction, the Section 87A rebate (tax-free up to ₹12L taxable in the new regime, ₹5L in the old), then add 4% cess and any surcharge. Old-regime tax is computed after your 80C and other deductions.
Common questions
- Is income up to ₹12 lakh really tax-free?
- In the new regime for FY 2025-26, the Section 87A rebate makes tax zero up to ₹12L of taxable income (₹12.75L gross for salaried, after the ₹75,000 standard deduction). Earn a rupee more and normal slabs apply — with marginal relief near the edge.
- Which regime should I choose?
- If your deductions (80C, 80D, HRA, home-loan interest) are large, the old regime often wins. If you don't claim many deductions, the new regime almost always wins. This calculator does the maths for your exact numbers.
- Can I switch regimes every year?
- Salaried individuals without business income can choose afresh each year while filing. Those with business income face restrictions on switching back.
