Estimate for ordinary income only. Not tax advice. Special-rate income (for example capital gains) is not included.
How to use the Income Tax Calculator
- Choose a rule set: India (new or old regime) or custom slabs.
- Enter your annual income and, for the old regime, your deductions.
- Compare the tax, cess, rebate and effective tax rate.
Rules used
The India rule sets apply the slab rates, standard deduction, Section 87A rebate (with marginal relief under the new regime) and 4% health and education cess for the financial year shown next to the result. Surcharge for incomes above ₹50 lakh is included. Tax rules change with each Budget; the effective date of the rule set is always displayed, and administrators can update the rules without changing tool code.
For other countries choose Custom slabs and enter the brackets and rates from your tax authority. The result is an estimate for planning, not tax advice. Special income such as capital gains is taxed differently and is not covered.
