We read everything. Replies usually take a few business days — this is a small team, and tax-season spikes are real.

Reporting a calculation error

To fix a mistake fast, include:

  • The page address (for example globalvatcalc.com/reverse-vat/).
  • The numbers you entered — amount, rate, and mode (add or remove).
  • What you expected and what you saw.
  • Any official source showing the correct figure, if the issue is a rate.

Confirmed errors are corrected and the page's review date is updated; meaningful corrections are noted on the page itself.

Suggest a country or a feature

We add country calculators as the site grows — tell us which country you need, and what you find hardest about its VAT rules. Requests that come up repeatedly get prioritised.

Advertising and business

For advertising or partnership enquiries, use the same address with “Business” in the subject line. We keep advertising clearly separated from editorial content — no calculator result is ever affected by a commercial relationship.

A note on tax advice

We cannot review your specific tax position or tell you which rate to apply to a transaction — that is regulated advice, and it depends on details a calculator never sees. Your accountant or the tax authority is the right place for those questions. (For arithmetic, that is what we are for.)
