Old vs New Tax Regime Comparison

Compare your income tax under the old and new regimes using slabs our expert team has verified, with the working shown.

Total income before any deduction. In rupees, for example 125000 or 1,25,000.50

For example the total of the deductions you would claim in the old regime. Leave empty if none

The standard deduction of each regime is given only if this is ticked

This comparison is for a resident individual below 60 years of age: the old-regime slabs for older taxpayers and the residence condition of the rebate are not worked out here. Under the Income-tax Act, 2025 the new-regime slabs are in section 202, the rebate in section 156 and the standard deduction in section 19; the rates for the year come from the Finance Act.

How this works

  1. Choose the tax year and enter your gross income, any old-regime deductions, and whether it includes salary or pension.
  2. We compute the tax under each regime from the verified slabs, rebate, standard deduction, surcharge, marginal relief and cess.
  3. A comparison is shown only when every part of both regimes has been verified for the year. Otherwise we show no number.

About this tool

What it does
Compares your income tax for the year under the old and the new regime from your income and deductions, and shows which comes out lower.
The rule it rests on
Income-tax Act, 2025: the new-regime slabs in section 202 and the rebate in section 156, with the surcharge and cess of the Finance Act for the year; the old-regime rates come from the First Schedule to that Finance Act. Every slab, rebate and deduction limit the tool uses is an approved rule row. Official source: Income-tax Act, 2025, section 202 (new tax regime for individuals)
Checked on
11 November 2026. Where a figure the tool shows is still to be verified by our expert team, the tool says so instead of showing it.
Next step
Once the regime is chosen, check which return form fits your sources of income. Which ITR form do I need?
