Old vs new — the short version

Old regime

Higher slab rates, but you can claim HRA, 80C (₹1.5L), 80D, home loan interest (₹2L self-occupied), 80CCD(1B) NPS (₹50K) and 70+ other deductions. Standard deduction ₹50,000. Section 87A rebate up to ₹12,500 if income ≤ ₹5L. Senior citizens get higher exemptions.

Wins when: you pay metro rent, have a home loan, fully use 80C, and contribute to NPS.

New regime (default)

Lower, broader slabs (nil up to ₹4L; 30% only above ₹24L). Standard deduction ₹75,000. Section 87A rebate up to ₹60,000 makes income ≤ ₹12L tax-free. HRA, 80C, 80D and most exemptions disallowed. Surcharge capped at 25%.

Wins when: few deductions — own house, no home loan, limited 80C, junior or freelancer.

Common questions

What are the new tax regime slabs for FY 2025-26? +
Under the new tax regime (Section 115BAC) for FY 2025-26 / AY 2026-27: Up to Rs 4 lakh is nil, Rs 4-8 lakh at 5%, Rs 8-12 lakh at 10%, Rs 12-16 lakh at 15%, Rs 16-20 lakh at 20%, Rs 20-24 lakh at 25%, and above Rs 24 lakh at 30%. A 4% Health and Education Cess applies on top.
Is income up to Rs 12 lakh tax-free under the new regime? +
Yes. The Finance Bill 2025 raised the Section 87A rebate to Rs 60,000, making total income up to Rs 12,00,000 effectively tax-free for resident individuals under the new regime. With the Rs 75,000 standard deduction, salaried employees with gross income up to Rs 12,75,000 pay zero tax. Marginal relief applies just above the Rs 12 lakh threshold.
What deductions are still allowed in the new tax regime? +
Under the new regime you can still claim: Standard Deduction of Rs 75,000, employer NPS contribution under Section 80CCD(2), gratuity exemption, leave encashment exemption (capped at Rs 25 lakh), and a few other employer-paid components. HRA, LTA, 80C (PPF, ELSS, insurance), 80D, 80CCD(1B), and home loan interest on self-occupied property are NOT allowed.
When does the old regime save more tax than the new regime? +
The old regime usually wins when you have substantial deductions: HRA in a metro city, full Rs 1.5 lakh in 80C, Rs 2 lakh home loan interest, Rs 25-50K in 80D health insurance, and Rs 50K in 80CCD(1B) NPS. As a rough rule, you need around Rs 4-5 lakh in total deductions (over the standard deduction) for old regime to beat the new regime at most salary levels.
Do senior citizens get a higher exemption under the new regime? +
No. Section 115BAC slabs are uniform across all ages — there is no separate exemption for senior or super-senior citizens under the new regime. The senior citizen basic exemption (Rs 3 lakh for 60-79, Rs 5 lakh for 80+) only applies under the old regime.
Can I switch between old and new regime every year? +
Salaried taxpayers without business income can switch regimes every year — declare your choice to your employer at the start of the financial year for TDS purposes, or finalize it when filing your ITR. Taxpayers with business or professional income can only switch back to the old regime once in a lifetime via Form 10-IEA.
Is this calculator accurate for FY 2025-26? +
Yes. The calculator uses FY 2025-26 (AY 2026-27) slabs from the Budget 2025 announcement, the Rs 75,000 standard deduction under the new regime, the Rs 60,000 Section 87A rebate up to Rs 12 lakh income, surcharge thresholds with the 25% cap under the new regime, and the standard 4% Health and Education Cess. Treat results as indicative — consult a chartered accountant for filing decisions.
