Old vs New Tax Regime FY 2025-26: How to Choose
Every salaried Indian faces the same annual question at tax-filing time: old regime or new regime? For FY 2025-26 (assessment year 2026-27), the choice has become sharper because Budget 2025 made the new regime far more generous, effectively taking income up to ₹12 lakh out of the tax net for most people. This guide explains what changed, how the break-even works, and how to decide which one actually saves you more.
The two regimes in one paragraph
The old regime has higher tax rates but lets you claim a long list of deductions and exemptions — Section 80C, 80D, House Rent Allowance (HRA), home loan interest and more. The new regime offers lower slab rates and a larger standard deduction, but strips away almost all of those deductions. In short: the old regime rewards people who invest and spend in tax-saving ways, while the new regime rewards simplicity with lower headline rates.
What the new regime looks like for FY 2025-26
Under Budget 2025, the new regime is now the default. Its slab structure (as of 2025) is as follows:
| Income slab (₹) | Tax rate |
|---|---|
| Up to 4,00,000 | Nil |
| 4,00,001 – 8,00,000 | 5% |
| 8,00,001 – 12,00,000 | 10% |
| 12,00,001 – 16,00,000 | 15% |
| 16,00,001 – 20,00,000 | 20% |
| 20,00,001 – 24,00,000 | 25% |
| Above 24,00,000 | 30% |
Two features make this powerful. First, a standard deduction of ₹75,000 is available to salaried taxpayers. Second, an enhanced Section 87A rebate means that if your taxable income is up to ₹12 lakh, your tax liability is effectively reduced to zero. Combined with the standard deduction, a salaried person can have a gross salary of around ₹12.75 lakh and still pay no tax under the new regime. Note that the rebate applies only to normal income, not to special-rate income such as capital gains.
What the old regime still offers
The old regime keeps its familiar slabs (nil up to ₹2.5 lakh, 5% up to ₹5 lakh, 20% up to ₹10 lakh, 30% above), with an 87A rebate for taxable income up to ₹5 lakh and a standard deduction of ₹50,000. Its appeal lies entirely in deductions:
- Section 80C — up to ₹1.5 lakh for EPF, PPF, ELSS, life insurance premiums, home loan principal and children's tuition fees.
- Section 80D — health insurance premiums for yourself and your parents.
- HRA exemption — for those paying rent, often a large amount in metro cities.
- Section 24(b) — up to ₹2 lakh of home loan interest on a self-occupied property.
- Section 80CCD(1B) — an additional ₹50,000 for NPS contributions.
The break-even logic
The decision comes down to a single question: are your total deductions large enough that the old regime's tax saving beats the new regime's lower rates? The more you can legitimately claim, the more the old regime tilts in your favour.
Rule of thumb: the heavier your genuine deductions, the more likely the old regime wins. If you claim little beyond the standard deduction, the new regime almost always wins.
For example, someone who maxes out 80C, pays substantial HRA in a metro, has health insurance and is servicing a home loan can stack up several lakhs of deductions. For that person the old regime may still be cheaper. But a young professional living with family, with no home loan and minimal investments, will usually pay less under the new regime — and with far less paperwork.
A simplified comparison
Consider a salaried person earning ₹15 lakh a year. The outcome depends heavily on deductions claimed:
| Situation | Likely better regime |
|---|---|
| Few or no deductions | New regime |
| Only 80C fully used (₹1.5 lakh) | Usually new regime |
| 80C + 80D + significant HRA | Closer call, lean old |
| 80C + 80D + HRA + ₹2 lakh home loan interest | Often old regime |
These are illustrations of the direction, not exact figures — your real answer depends on your precise numbers, so always compute both. The income tax calculator lets you enter your income and deductions and compare the two regimes side by side, and if rent is a big part of your package, the HRA calculator helps you work out exactly how much of your HRA is exempt under the old regime.
How to decide, step by step
- Add up every deduction you can genuinely claim: 80C, 80D, HRA, home loan interest, NPS.
- Compute your tax under the old regime with those deductions.
- Compute your tax under the new regime with the ₹75,000 standard deduction.
- Pick whichever produces the lower liability — and re-check the numbers, not last year's habit.
An important point for salaried taxpayers: you can choose your regime afresh every financial year. So a job change, a new home loan or a big shift in your investments can flip the answer from one year to the next. Taxpayers with business or professional income have more restrictive switching rules, so they should check the current provisions carefully.
Key takeaways
- The new regime is the default and makes taxable income up to ₹12 lakh effectively tax-free via the enhanced 87A rebate (as of 2025).
- The old regime only wins when your genuine deductions are large — think maxed 80C plus HRA plus home loan interest.
- Salaried taxpayers can switch regimes every year, so recompute annually.
- Use the income tax calculator and HRA calculator to compare with your own figures.
- Slabs and rebate limits can change in future budgets — verify the current rules before you file. This is educational information, not personalised tax advice.
