Income Tax Calculator

An income tax calculator computes your tax liability under both the Old and New Tax Regimes side by side, applying each regime's slab rates and allowed deductions so you can compare and choose.

Formula

Tax is computed by applying the applicable financial year's progressive slab rates to taxable income (gross income minus regime-specific deductions/exemptions), plus applicable cess.

Worked example

Input: ₹15,00,000 gross income

Result: Old Regime tax (after eligible deductions like 80C, HRA) compared against New Regime tax (lower slabs, minimal deductions) — the lower of the two determines the better choice

Frequently asked

Which regime should I choose?

It depends on how many deductions (80C, HRA, home loan interest, etc.) you actually claim — high-deduction taxpayers often save more under the Old Regime, while those with few deductions usually benefit from the New Regime's lower slabs.

Can I switch regimes every year?

Salaried individuals can choose a regime each financial year when filing returns; those with business income face more restrictions on switching back and forth.

Income Tax Calculator: how it works

An income tax calculator applies the slab rates of both Indian regimes to your income and deductions, showing the tax payable under each so you can pick the cheaper one.

Formula

Tax = Σ (income within each slab × that slab's rate), plus applicable cess, computed separately for the old and new regime slabs.
