What it does
This calculator estimates income tax for a resident individual under both regimes for tax year 2026-27 (1 April 2026 to 31 March 2027), and shows which one gives the lower tax on the figures you enter. It applies the slab rates, the standard deduction for salaried people and pensioners, the rebate, surcharge with marginal relief, and the 4% health and education cess.
| New regime: taxable income | Rate |
|---|---|
| ₹0 to ₹4,00,000 | Nil |
| ₹4,00,000 to ₹8,00,000 | 5% |
| ₹8,00,000 to ₹12,00,000 | 10% |
| ₹12,00,000 to ₹16,00,000 | 15% |
| ₹16,00,000 to ₹20,00,000 | 20% |
| ₹20,00,000 to ₹24,00,000 | 25% |
| Above ₹24,00,000 | 30% |
| Old regime (below 60): taxable income | Rate |
|---|---|
| ₹0 to ₹2,50,000 | Nil |
| ₹2,50,000 to ₹5,00,000 | 5% |
| ₹5,00,000 to ₹10,00,000 | 20% |
| Above ₹10,00,000 | 30% |
In the old regime the first slab ends at ₹3,00,000 for people aged 60 to 79 and at ₹5,00,000 for people aged 80 or above.
How to use it
- Enter your income for the year before any deductions.
- Choose salary or pension if the standard deduction applies to you.
- Choose your age group. It only changes the old-regime slabs.
- Enter the total of the deductions you would claim under the old regime. Leave it at 0 if you have none.
- Compare the two results.
Worked example
Salary of ₹15,00,000 with ₹1,50,000 of old-regime deductions. New regime: taxable income is ₹14,25,000 after the ₹75,000 standard deduction; tax is ₹93,750 plus 4% cess, ₹97,500. Old regime: taxable income is ₹13,00,000 after the ₹50,000 standard deduction and the deductions; tax is ₹2,02,500 plus cess, ₹2,10,600. The new regime is lower by ₹1,13,100.
How it works
Taxable income is income minus the standard deduction (₹75,000 in the new regime, ₹50,000 in the old) and, in the old regime only, the deductions you enter. Tax is then worked out slab by slab.
Rebate. A resident individual pays no tax in the new regime if taxable income is ₹12,00,000 or less, and in the old regime if it is ₹5,00,000 or less. Just above ₹12,00,000 in the new regime, marginal relief limits the tax to the income above that figure.
Surcharge applies above ₹50 lakh of income, with marginal relief, and the 4% cess is added last.
Questions
Which regime applies if I do nothing?
The new regime is the default. You have to opt for the old regime if you want it.
Why is there no tax up to ₹12.75 lakh of salary?
In the new regime the ₹75,000 standard deduction brings a salary of ₹12,75,000 down to ₹12,00,000 of taxable income, and the rebate then removes the tax.
What does this calculator not cover?
Capital gains and other income taxed at special rates, non-residents, HUFs and businesses, and the detailed limits on each deduction. The rebate does not apply to income taxed at special rates.
Are deductions like 80C allowed in the new regime?
Most are not. That is why the deductions box only affects the old-regime result.
Is this tax advice?
No. It is an estimate for planning. Use the Income Tax Department’s own calculator or a tax professional before you file.
