Old vs New Tax Regime: Which Saves You More in FY 2025-26?

Every April, salaried Indians have to tell their employer which tax regime to apply — and most pick wrong, or pick blindly. After Budget 2025 the maths changed sharply in favour of the new regime, but not for everyone. This guide compares both at real salary levels, shows the exact point where the old regime still wins, and gives you a simple rule to decide.

The new regime slabs for FY 2025-26

These are the slabs announced in Budget 2025 (applicable for the financial year 2025-26, assessment year 2026-27):

Two things make this generous: a ₹75,000 standard deduction for salaried taxpayers, and a Section 87A rebate that fully cancels the tax when taxable income is ₹12 lakh or less. Together they mean a salaried person earning up to ₹12.75 lakh pays zero tax.

Old vs new: the numbers at each salary

The comparison below assumes a taxpayer using ₹2.25 lakh of deductions under the old regime (the ₹50,000 standard deduction + a full ₹1.5 lakh under Section 80C + ₹25,000 under 80D). All figures include the 4% health & education cess.

With ordinary deductions, the new regime wins comfortably at every level.

So when does the old regime still win?

Only when your deductions are large. Take a ₹15 lakh salary: the new regime charges ₹97,500. For the old regime to match that, you would need to bring your taxable income down to about ₹9.06 lakh — which means claiming roughly ₹5.9 lakh in total deductions. In practice that requires a home loan (up to ₹2 lakh of interest under Section 24), a full ₹1.5 lakh under 80C, meaningful HRA, and 80D health insurance, all at once.

The simple rule: if you have a home loan and max out your other deductions, run both regimes. Otherwise, the new regime almost certainly wins. The fastest way to check your own case is our income tax calculator, which computes both side by side in seconds.

What the new regime takes away

The new regime's low rates come at the cost of nearly all deductions and exemptions: no 80C, no 80D, no HRA exemption, no home-loan interest (for a self-occupied house), no LTA. If your financial life is built around these — especially HRA in an expensive metro plus a home loan — the old regime can still be worth the paperwork. If not, the new regime is simpler and cheaper.

A note on tax-saving investments

Under the new regime, the tax benefit of 80C instruments disappears — but that does not make them useless. A PPF account still earns tax-free interest, and equity mutual funds via SIP still build wealth. Choose investments for their own merit now, not just to save tax.
