Career & HR calculators

The engine is cross-checked against official sources — the IRS, GOV.UK, gov.scot and India’s Income Tax Department — and locked down with golden tests at the tricky boundaries (slab edges, the §87A rebate cliff, the UK personal-allowance taper). Every tool cites its sources and a last-updated date. They’re estimates for planning, not formal tax advice.

No. Every calculator is free, needs no account, and runs entirely in your browser — your salary and other inputs are never sent to a server. You can also share a result via a link or embed a tool on your own site.

Tax tables are reviewed every tax year — and immediately when major legislation changes them — through a human-reviewed update, never an automatic scrape. The tax year is labelled on every tool so you always know which rules a result is based on.
