Surcharge and cess
Surcharge applies on tax when income exceeds ₹50 lakh (10%), ₹1 crore (15%), ₹2 crore (25%) and, in the old regime only, ₹5 crore (37%). Marginal relief ensures the extra tax is never more than the income above each threshold. A 4% health and education cess is then added to tax plus surcharge.
This calculator is for estimates and planning. Your actual tax may differ – for example with capital gains, arrears or special-rate income. Confirm with Form 16, your employer or a tax professional.
Frequently asked questions
How much salary is tax-free in the new regime?
For FY 2025-26, salary up to ₹12,75,000 is effectively tax-free under the new regime: the ₹75,000 standard deduction brings taxable income to ₹12 lakh, and the section 87A rebate cancels the tax up to that level. Just above ₹12 lakh of taxable income, marginal relief makes sure the tax is never more than the income above ₹12 lakh.
What are the new regime tax slabs?
From FY 2025-26: up to ₹4 lakh – nil; ₹4–8 lakh – 5%; ₹8–12 lakh – 10%; ₹12–16 lakh – 15%; ₹16–20 lakh – 20%; ₹20–24 lakh – 25%; above ₹24 lakh – 30%. Add 4% health and education cess.
Which regime is better for me?
The new regime usually wins unless you claim large deductions. For example, on a ₹10 lakh salary with ₹1.5 lakh in 80C and ₹25,000 in 80D, the old regime tax is ₹70,200 while the new regime tax is nil. The calculator shows how much more you’d need in deductions to make the old regime worthwhile.
What tax do I pay on a ₹15 lakh salary?
Under the new regime for FY 2025-26, taxable income is ₹14.25 lakh after the standard deduction, and tax with cess is ₹97,500 – about ₹8,125 a month.
Which deductions are allowed in the new regime?
Mainly the ₹75,000 standard deduction and your employer’s NPS contribution under section 80CCD(2). Deductions like 80C, 80D, HRA and home loan interest on a self-occupied house are only for the old regime.
What are the old regime slabs for senior citizens?
Below 60: nil up to ₹2.5 lakh. Senior citizens (60–79): nil up to ₹3 lakh. Super senior citizens (80+): nil up to ₹5 lakh. Then 5% up to ₹5 lakh, 20% up to ₹10 lakh and 30% above, with a rebate that makes tax nil up to ₹5 lakh of taxable income.
Is FY 2026-27 the same as FY 2025-26?
This calculator applies the FY 2025-26 slabs, standard deduction and rebate to FY 2026-27 as well. If a later Finance Act or rule changes them, check the latest notification and adjust.
Does it handle capital gains or business income?
No. It covers salary, interest and rental income at normal slab rates. Capital gains, lottery winnings and business income have special rules – use the official income tax e-filing calculator or a tax professional for those.
