Why I built TaxWize

Every spring, ordinary Swiss taxpayers face the same problem. Cantonal portals walk you through the forms but don't tell you what you might be missing. A tax advisor for a standard situation feels like overkill.

For more than six years I led regulatory tax projects across CRS, FATCA, and US Withholding Tax, rule sets far more complex than individual Swiss taxation. The same discipline goes into TaxWize, the tool I wished existed when filing my own taxes.

Background

• Led regulatory tax projects across CRS, FATCA, and US Withholding Tax at Credit Suisse.
• PMP-certified since 2019; degrees in Project Management and Finance & Banking from Babes-Bolyai University.
• Speaks four languages fluently: English, German, Hungarian, Romanian.

Built to be trusted

• Your data stays in Switzerland. Stored in Zurich, hosted by Supabase on AWS eu-central-2.
• Every subprocessor under contract. Signed DPAs with Supabase, Google Cloud, Stripe, and Resend. See the full list.
• A registered Swiss entity. Szakács Solutions, eingetragenes Einzelunternehmen, UID CHE-289.567.114. Aargau commercial register.
• Honest about what we are. TaxWize prepares you to file; the canton remains your filing authority. We say "worth checking" and "may be relevant", not "you're entitled to".

TaxWize provides tools and information to help you prepare your Swiss tax declaration. It is not licensed tax advice. For complex situations, consult a qualified Swiss tax advisor.
