Frequently asked questions
Quick answers about how GlobalPayCalc works.
Is GlobalPayCalc free to use?
Yes. All calculators and guides are free. Results are educational estimates only and are not financial, tax, or legal advice.
Which countries do you support?
We currently offer tools for the United States, United Kingdom, Australia, Pakistan, Canada, and Germany. More countries can be added over time.
Where do tax rates come from?
Tax figures are stored in country data files and linked to official authorities. Until a file is verified, it may be marked TODO_VERIFY — always confirm against the official source before relying on a number.
Can I use these calculators for my tax return?
No. Use official filing tools or a qualified adviser in your country. Our calculators are for planning and learning only.
Do you store the numbers I enter?
Calculator inputs stay in your browser. We do not require an account. If you contact us, we only receive what you send in that message.
Will you add more calculators?
Yes. We expand tools and guides over time. Use the contact form to suggest a calculator or report outdated data.
