Frequently Asked
What is TaxSentry?
TaxSentry is an independent service of tools and calculators for tax optimization in Switzerland. We help estimate savings opportunities and check eligibility for tax deductions.
How accurate are the calculations?
Our calculators provide estimated results based on current cantonal tax rules. They are intended for guidance, not final tax planning. For precise calculations, always consult a qualified professional.
Are my data safe?
Yes, your privacy is our absolute priority. We operate on a zero-storage principle: calculation data is processed exclusively in-memory and is not saved in our databases. The only information we collect is anonymous technical analytics (e.g., Umami Analytics) solely to improve site usability. This data is in no way connected to your calculations and is completely anonymous.
Which taxes does the service consider?
We consider federal, cantonal, and municipal income taxes, as well as the specifics of church tax in various regions of Switzerland.
For which cantons does it work?
Currently, our tools support all 26 Swiss cantons based on data current as of February 2026.
