Built to make tax maths boring

Artha is a free income tax estimator for individuals in India. It computes your liability separately under the New and Old Regime for the selected financial year and shows exactly how each number was reached — slab by slab, deduction by deduction.

Private by design

Every calculation happens inside your browser. Your income details are stored only on this device and are never uploaded.

Transparent workings

Instead of a single number, you get the slab-wise tax, exemptions, capped deductions, rebate, surcharge and cess, so you can check the logic yourself.

Kept current

All slabs, limits, rebates and rates live in one configuration file per financial year, so the app can be updated quickly after each Union Budget.

What it does not cover

Presumptive business taxation, foreign income and DTAA relief, relief under Section 89, clubbing of income, carried-forward losses, and firm or company taxation are outside its scope.

This tool provides estimates for educational and planning purposes only. It is not official tax advice and is not a substitute for filing a return with the Income Tax Department of India.
