Income Tax Calculator

Old vs. new regime, side by side — with every deduction applied only where that regime actually allows it.

This is a calculator, not tax advice. It estimates outcomes based on publicly available rules and typical provider pricing — it does not account for your specific circumstances. Rules and rates change. Verify anything you rely on with a qualified CA before you act on it.

FY 2026-27 slabs are not yet in this tool — Budget 2026 was presented after this tool's data was last verified. Figures below use FY 2025-26 rates; confirm the current year's slabs with your CA.

How this is calculated

Both regimes start from your gross salary plus other income, then subtract the standard deduction (₹50,000 old / ₹75,000 new) and any employer NPS contribution under Section 80CCD(2), which both regimes allow. The old regime additionally subtracts your HRA exemption, Section 80C investments (capped at ₹1.5L), Section 80CCD(1B) NPS contribution (capped at ₹50,000), Section 80D health insurance, and any other Chapter VI-A deductions you enter — none of which apply under the new regime.

The resulting taxable income runs through the same slab-and-rebate engine used across this site's tax tools, including proper Section 87A marginal relief rather than a hard cliff at the rebate threshold.

Frequently asked questions

Which deductions actually apply under the new regime?

Almost none of the classic ones — no HRA exemption, no 80C, no 80D, no 80CCD(1B). The two big exceptions: the standard deduction (₹75,000 under the new regime vs. ₹50,000 under the old) and Section 80CCD(2), your employer's NPS contribution, which survives under both regimes. This calculator applies each deduction only where it's actually valid, rather than letting you double-count something the new regime doesn't allow.

Why is the old regime standard deduction different from the new regime's?

The new regime's standard deduction was raised to ₹75,000 as part of a broader push to make the new regime more attractive after the July 2024 Budget; the old regime's has stayed at ₹50,000. It's a small but real part of why the comparison isn't as simple as 'old regime has more deductions, so it always wins' — it depends on how much of the old regime's other deductions you actually use.

Can I switch between regimes every year?

If your income is from salary (not business/professional income), yes — you can choose either regime each year when filing. If you have business or professional income, switching back to the old regime after opting for the new one has restrictions, so that choice is less flexible.
