About NetPay Atlas

By NetPay Atlas Editorial TeamUpdated How we calculate

We build free, transparent pay and tax calculators using rates published by tax authorities (IRS, HMRC, CRA, ATO, Revenue). Every formula is documented on our methodology page.

Our standards

  • Rates come only from tax authorities and recognised references, which are linked on every page.
  • Every assumption and limitation is listed on our methodology page.
  • We review rate tables at the start of every tax year and whenever governments announce changes.
  • Calculations run in your browser. We never collect the salaries you type.

How we're funded

NetPay Atlas is free and supported by display advertising. Advertisers have no influence over our calculations or content, and we do not sell personal data.

Not financial advice

Our tools give estimates for general information. For decisions about tax, pensions or debt, please talk to a qualified professional or your tax authority.
