How it is calculated
Tax = (slab tax − 87A rebate + surcharge) × 1.04
Taxable income is gross income minus deductions, rounded to the nearest ₹10. New regime slabs for FY 2026-27: up to ₹4 lakh nil, 4 to 8 lakh 5%, 8 to 12 lakh 10%, 12 to 16 lakh 15%, 16 to 20 lakh 20%, 20 to 24 lakh 25%, above 24 lakh 30%. Old regime: up to ₹2.5 lakh nil (₹3 lakh at 60 to 80, ₹5 lakh at 80+), up to 5 lakh 5%, 5 to 10 lakh 20%, above 10 lakh 30%.
The 87A rebate takes away tax up to ₹60,000 when taxable income is up to ₹12 lakh (new) or ₹12,500 up to ₹5 lakh (old). Just above ₹12 lakh, marginal relief caps the tax at the income above ₹12 lakh. Surcharge also has marginal relief, so crossing ₹50 lakh never costs more than the extra income. HRA exemption is the least of HRA received, rent minus 10% of basic, and 50% of basic (40% outside metros). Source: Finance Act 2025, rates kept for FY 2026-27.

- Employer NPS under 80CCD(2) is one of the few deductions that also counts in the new regime.
- Salaried people can change regime every year when filing the return. Business owners have fewer switches.
- Every input is kept in the page link, so Copy link shares the exact comparison.

Questions people ask
Is income up to 12 lakh tax free in the new regime?
Yes, for normal income such as salary. Taxable income up to ₹12 lakh gets a rebate of up to ₹60,000, which wipes out the tax. With the ₹75,000 standard deduction, a salary of ₹12.75 lakh pays no tax. Just above the limit, marginal relief keeps the tax no more than the income above ₹12 lakh.
Which regime should I choose?
Enter your salary and deductions and the calculator shows both side by side. As a rough rule, the old regime only wins when you claim large deductions, such as full 80C, home loan interest and HRA together.
Which deductions are allowed in the new regime?
Mainly the ₹75,000 standard deduction for salaried people and the employer's NPS contribution under 80CCD(2), up to 14% of basic pay and DA. 80C, 80D, HRA and home loan interest on a self-occupied house are not allowed.
What are surcharge and cess?
Surcharge is extra tax on high incomes: 10% above ₹50 lakh, 15% above ₹1 crore, 25% above ₹2 crore (and 37% above ₹5 crore in the old regime). Health and education cess is 4% on tax plus surcharge, and everyone pays it.
Are FY 2026-27 rates different?
No. The 2026 budget kept the same slabs, rebate and deductions for FY 2026-27. The new Income-tax Act 2025 starts from April 2026 and gives the sections new numbers, but the familiar names such as 80C are used here.
Does it cover capital gains?
No. Gains on shares and mutual funds have their own rates and do not get the 87A rebate. Add only normal income such as salary, interest and rent here. This is an estimate; check with your tax adviser before filing.
