What to write about
- A result looks wrong. Send the page link (the address keeps your inputs), what you expected, and the source you are comparing with — a payslip line or an official calculator. Confirmed errors are fixed and logged on the changelog.
- A missing state, province or calculator. Tell us which one.
- Embedding the calculator on a business, accounting or staffing site.
- Using the data files in an article or app.
What we cannot help with
Netpaysum cannot give personal tax advice, review your tax return or contact your employer. For your own situation, use the official tax authority or a qualified professional.
Please don't send payslips, tax IDs or bank details — the numbers and the page link are enough.
