How it works

Old: slabs 2.5L nil / 5% to 5L / 20% to 10L / 30% above on (income − all deductions), rebate ₹12,500 to ₹5L. New: 2025-26 slabs on (income − ₹75,000 − 80CCD(2)), rebate to ₹12L. Both + surcharge + 4% cess

Salaried taxpayers can still choose the old regime each year (business taxpayers can switch only once). The old regime keeps the 2.5/5/10 lakh slabs and a smaller ₹50,000 standard deduction but allows the full menu of deductions: Section 80C investments up to ₹1.5 lakh, 80D health premiums, HRA, LTA, home-loan interest up to ₹2 lakh, extra NPS and more. The new regime’s lower slabs and ₹12 lakh rebate mean it wins for most people unless deductions are unusually large — typically the break-even sits between ₹5 and ₹8 lakh of deductions depending on income. The calculator reports the extra deductions you would need to make the old regime worthwhile.

Worked example

Salary ₹18 lakh with ₹1.5L 80C, ₹25k 80D, ₹1.2L HRA and ₹2,500 professional tax: old regime taxable ₹14.52L → ₹2,58,180 incl. cess; new regime taxable ₹17.25L → ₹1,50,800. New regime saves about ₹1,07,400; the old regime would need roughly ₹3.45 lakh more in deductions to catch up.

Frequently asked questions

Can I switch back to the old regime next year?

Salaried individuals can pick either regime every year at filing time. Those with business income get one switch back to old only.

Is HRA available in the new regime?

No. HRA, LTA, 80C, 80D, 24(b) on a self-occupied home and most other deductions are only in the old regime. The new regime keeps the standard deduction, 80CCD(2) and interest on a let-out property.
