Income Tax Calculator
Use this simplified calculator to explore how taxable income and an illustrative slab-based calculation can affect a tax estimate. It is not a substitute for the current official tax computation.

What is the Income Tax Calculator?
Tax is highly rule-dependent. The same income can produce different outcomes depending on the tax regime, deductions, rebates, capital gains, special rates, surcharge and other factors.
How the calculation works
The calculator subtracts the entered deductions from annual income, applies the simplified slab assumptions built into the tool, and adds the illustrative cess shown in the result. It does not model every current tax rule, regime choice, rebate, surcharge or special-rate income.
Worked example
If annual income is ₹1,000,000 and the entered deductions are ₹100,000, the illustrative taxable income is ₹900,000 before the simplified slab calculation. Actual liability can differ significantly depending on the applicable assessment year and circumstances.
