About the India Income Tax Calculator
India Income Tax Calculator works out the tax you pay under the new tax regime for the financial year 2025-26 (assessment year 2026-27). Enter your yearly income and say whether it is salary, and the page takes off the standard deduction of ₹75,000 and any employer contribution to NPS, applies the slab rates from 5% to 30%, gives the section 87A rebate that makes tax nil up to ₹12 lakh of taxable income, adds surcharge for very high incomes and 4% health and education cess. The answer shows the tax for the year and a month, in your browser.

How the new regime works
Under the new regime you pay tax on your taxable income, which is your income minus a flat standard deduction of ₹75,000 if you are salaried, and minus an employer NPS contribution if any. Tax is charged in steps: nothing on the first ₹4 lakh, then 5%, 10%, 15%, 20%, 25% and 30% on each further ₹4 lakh. Each rate applies only to the part of income inside its band.
The rebate and marginal relief
Section 87A gives a rebate that cancels the whole tax when taxable income is up to ₹12 lakh. Without any extra rule, someone at ₹12.05 lakh would suddenly pay about ₹60,000, so marginal relief limits the tax to the ₹5,000 by which they cross the limit. This page applies both, so you can see how income just around ₹12 lakh behaves.
- Salary ₹12.75 lakh or less: tax nil (after ₹75,000 standard deduction)
- Just above: tax equals the excess over ₹12 lakh of taxable income
- Above ₹15 lakh or so: normal slab tax applies in full
Using the result
The monthly figure helps you check the tax deducted from your payslip. Your employer may deduct differently if you have other income or choose another regime, and a refund or extra payment is settled when you file the return. If you are self employed, remember advance tax is due in instalments.

Frequently asked questions
What are the new regime tax slabs for FY 2025-26?
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% and above ₹24 lakh 30%.
Is income up to ₹12 lakh really tax free?
Taxable income up to ₹12 lakh gets a full rebate under section 87A, so the tax is nil. For a salaried person with the ₹75,000 standard deduction that means a salary up to ₹12.75 lakh. The rebate does not apply to special rate income such as capital gains.
What is marginal relief?
Just above ₹12 lakh the tax is limited to the amount by which your income exceeds ₹12 lakh, so you never pay more tax than the extra income you earned.
Does this include the old regime?
No. It shows the new regime, which is the default. The old regime has deductions such as 80C and HRA that need many more inputs.
What is cess?
A 4% health and education cess is added to the tax plus any surcharge.
Is surcharge exact?
The surcharge rates (10% above ₹50 lakh, 15% above ₹1 crore and 25% above ₹2 crore of taxable income) are applied simply, without marginal relief at the edges, so results for very high incomes are approximate.
Does it cover capital gains or TDS?
No. It covers ordinary income taxed at slab rates only. Capital gains, TDS already paid and advance tax are not included.
Can the rules change?
Yes. Tax rules are set each Budget. Check the income tax department's website or ask an accountant before you file.
