How it’s calculated

The maths, in plain words

New regime

Lower slab rates and a ₹75,000 standard deduction, but almost no deductions. Employer NPS contribution is still allowed.

Old regime

Higher rates, ₹50,000 standard deduction, but you can subtract 80C (₹1.5 L), 80D, home-loan interest (₹2 L), HRA, NPS (₹50,000 extra) and more.

Break-even

We search for the total deductions at which both regimes cost the same. Claim more than that and the old regime wins.

Which regime is better for ₹15 lakh salary?
Usually the new regime. At ₹15 lakh you need roughly ₹5–6 lakh of deductions before the old regime catches up — which means rent with a big HRA claim plus a home loan, not just 80C.
Can I switch regimes every year?
Salaried people can choose each year when filing their return. People with business income can switch back to the old regime only once.
What deductions work in the new regime?
The standard deduction, employer’s NPS contribution, and a few others like family pension deduction. 80C, 80D, HRA and home-loan interest on a self-occupied home don’t apply.
Does the new Income-tax Act change this?
The Income-tax Act, 2025 replaced the 1961 Act from 1 April 2026 and renumbered many sections, but Budget 2026 kept the slabs, rebate and deductions the same for FY 2026-27.
