About india income tax calculator
Old vs new tax regime comparison for AY 2025-26 with 80C/80D deductions. It sits in the calculators shelf alongside 140 other calculators tools, needs no account, and keeps the same behaviour whether you open it here or call it through the REST API.

India Income Tax Calculator questions
Does India Income Tax Calculator upload my file?
No. India Income Tax Calculator runs as WebAssembly inside this browser tab: the file is read from your disk by the page, processed on your own machine, and handed straight back. It is never sent anywhere, so there is nothing for us to store or delete.
Do I need an account to use India Income Tax Calculator?
No. India Income Tax Calculator works without signing in, and that is not a trial — it is how the free tier works. An account only matters for things that need one to exist at all: larger server jobs against your quota, API keys, saved workflows and billing.
Can I run India Income Tax Calculator from my own code?
Yes. Every tool on the site is reachable from the REST API with the same slug — `india-income-tax-calculator` — and the same options as this page, so anything you can do here you can automate against your own files.
