Income Tax Calculator
Compare the old and new tax regimes side by side.
Salaried taxpayers in India can choose between two regimes. The new regime has lower rates but allows almost no deductions. The old regime has higher rates but lets you claim deductions such as 80C, 80D, HRA and home-loan interest.
What this calculator assumes
- FY 2025-26 slabs, salaried individual below 60 years.
- New regime: standard deduction ₹75,000 and full rebate on taxable income up to ₹12 lakh.
- Old regime: standard deduction ₹50,000 and rebate on taxable income up to ₹5 lakh.
- 4% health and education cess is included.
Surcharge for very high incomes, capital gains and business income are not modelled. Tax rules change with each Budget, so confirm the latest slabs on the Income Tax Department website or with a chartered accountant before you file.

Frequently asked questions
Which regime is better for me?
If your total deductions are large (typically above ₹3–4 lakh), the old regime can win. Otherwise the new regime usually costs less. The calculator shows both.
Can I switch regimes every year?
Salaried individuals can generally choose each year. Business income earners have restrictions.
Is this advice?
