Old vs New Tax Regime FY 2025-26: Which Is Better?

By Dinesh Babu, Founder & Editor, PaisaCalc · Updated July 2026

Every salaried Indian faces the same question at the start of the financial year: old regime or new regime? For FY 2025-26 the new regime is the default, and it has become dramatically more attractive after the rebate was raised so that income up to ₹12 lakh is effectively tax-free. But the old regime is still the winner for people with large deductions. This plain-English guide walks through the exact slabs, the maths behind the choice, and worked examples so you can decide with confidence. Treat the numbers here as an estimate — always verify against the Income Tax Department or a qualified professional before filing.

The core difference in one line

The new regime offers lower tax rates and a bigger standard deduction, but takes away almost every other deduction and exemption. The old regime keeps higher rates but lets you claim deductions such as Section 80C (₹1.5 lakh), 80D (health insurance), HRA and up to ₹2 lakh of home-loan interest under Section 24(b).

So the decision is really a single question: do the deductions you actually claim save you more tax than the new regime's lower rates and larger rebate? If yes, stay on the old regime. If not, the new regime almost always wins — and it needs zero paperwork.

New regime slabs for FY 2025-26

The new regime is the default. It has a ₹75,000 standard deduction for salaried taxpayers and pensioners, and a Section 87A rebate that reduces tax to nil for taxable income up to ₹12,00,000 (a maximum rebate of ₹60,000). A 4% health and education cess applies on top of the tax computed.

Up to ₹4,00,0000%
₹4,00,001 – ₹8,00,0005%
₹8,00,001 – ₹12,00,00010%
₹12,00,001 – ₹16,00,00015%
₹16,00,001 – ₹20,00,00020%
₹20,00,001 – ₹24,00,00025%
Above ₹24,00,00030%

The headline benefit: zero tax up to about ₹12.75 lakh

Because of the Section 87A rebate, anyone with taxable income up to ₹12,00,000 pays no tax at all under the new regime. Add the ₹75,000 standard deduction that salaried people get automatically, and a salaried person can earn up to roughly ₹12,75,000 in gross salary and still pay zero income tax.

This is the single biggest reason the new regime now suits most salaried taxpayers, especially younger earners who have not yet built up large 80C investments, home loans or rent claims.

Old regime slabs for FY 2025-26

The old regime has a ₹50,000 standard deduction, and its Section 87A rebate makes income up to ₹5,00,000 taxable tax-free (a maximum rebate of ₹12,500). Its real strength is the long list of deductions it allows.

When the old regime still wins

The old regime is worth keeping when your deductions are large enough to pull your taxable income well below your gross. The more you claim, the better it looks. Common situations where it wins:

  • You use the full ₹1.5 lakh under Section 80C (EPF, PPF, ELSS, life insurance, tax-saver FD, home-loan principal, children's tuition).
  • You pay significant home-loan interest — up to ₹2 lakh is deductible under Section 24(b).
  • You live in rented accommodation in a metro and claim a large HRA exemption.
  • You contribute an extra ₹50,000 to NPS under Section 80CCD(1B) and pay health insurance premiums under 80D.
  • Stacked together, these can easily remove ₹4–5 lakh or more from your taxable income, which can outweigh the new regime's lower rates.

A worked comparison

Consider someone with a ₹15,00,000 gross salary. Under the new regime, after the ₹75,000 standard deduction, taxable income is ₹14,25,000 and tax is calculated on the new slabs plus 4% cess — with no other deductions allowed.

Under the old regime, suppose the same person claims the ₹50,000 standard deduction, ₹1.5 lakh under 80C, ₹50,000 NPS under 80CCD(1B), ₹25,000 under 80D and ₹2 lakh of home-loan interest. Taxable income falls to about ₹10.25 lakh, taxed on the old slabs. Whether old beats new here depends on exactly how many of those deductions are real for you — which is why you should never decide from a rule of thumb alone.

The break-even point shifts with your deductions. As a rough guide, if your total deductions (beyond the standard deduction) are modest, the new regime usually wins; if they run into several lakh, the old regime often pulls ahead.

The simplest way to decide

Don't guess — calculate both. Our income tax calculator computes your tax under both regimes side by side for your exact salary and deductions, and tells you which is cheaper. You can also switch regimes each year (unless you have business income, where rules are stricter), so re-check whenever your deductions change — for example after taking a home loan or moving to a rented home.

Frequently asked questions

  • Is the new regime compulsory? No. It is the default, but salaried taxpayers can opt for the old regime while filing their return.
  • Can I switch every year? Salaried individuals without business income can generally choose afresh each year.
  • Does the ₹12 lakh rebate apply to the old regime? No — the ₹12 lakh 87A rebate is a new-regime feature. The old regime's 87A rebate covers income up to ₹5 lakh.
  • Do these figures include cess? A 4% health and education cess applies on the computed tax under both regimes.
  • Is this financial advice? No. This is an educational estimate for FY 2025-26 — verify with the Income Tax Department or a qualified tax professional before acting.
