Do the tools cost anything?

No. All calculators and checkers are free, require no sign-up and have no usage limit.

Is what I enter stored or transmitted?

No. All calculations run entirely in your browser. Amounts, IBANs and references never leave your device and are not stored anywhere.

How current are the rates and thresholds?

Each tool states when it was last reviewed and lists its sources, such as the Swiss Federal Tax Administration (FTA) for VAT and net tax rates, the Swiss Code of Obligations for default interest and the SIX guidelines for QR references.

Are the results binding?

No. The tools follow the legal basis and common conventions but do not replace tax or legal advice. For binding answers, contact the FTA or your fiduciary.

Do the tools work on a smartphone?

Yes. All tools are built for smartphone, tablet and desktop. Once loaded, they calculate without contacting any server.
