What is Avenzo?
Avenzo combines tax filing, insurance comparison and fiduciary services in a single app — FINMA-registered, across all 26 cantons.

Tax calculation for all 26 cantons is free and non-binding with Avenzo. Flat-fee tax-return filing (EINFACH / STANDARD / PREMIUM) is available from CHF 89 — fixed prices with no hidden fees. For the insurance comparison, Avenzo — as a non-tied FINMA-registered intermediary — receives standard brokerage commissions directly from the insurer; these are disclosed and fund the platform.
Avenzo is FINMA-registered (F01567880) and subject to Swiss Financial Market Supervision. All data is stored exclusively on Swiss servers with AES-256 end-to-end encryption. Two-factor authentication is mandatory for all accounts. DSG and GDPR compliant.
Every filing through Avenzo is reviewed by an expert from our Swiss tax and fiduciary team. The AI prepares the return (salary statement scan, deduction detection, cantonal logic); the expert performs the review typically within 24 hours, then Avenzo files directly with the canton.
Avenzo doesn't necessarily replace your existing fiduciary — you can use Avenzo for preparation, receipt capture, and calculation, then hand the data to your fiduciary. For everything in one place: our fiduciary team reviews every filing anyway, and the flat-fee filing plan (from CHF 89) also covers the complete handling.
Avenzo is available for all 26 Swiss cantons. Direct e-filing is supported in Zurich, Bern, Aargau, Lucerne, St. Gallen, Zug, and Basel-Stadt, plus other cantons with digital submission interfaces. For all other cantons, Avenzo generates the correct cantonal PDF form.
Avenzo is registered with FINMA as a non-tied insurance intermediary (F01567880) and compares all licensed Swiss insurers for health insurance, Pillar 3a, life and liability — without ties to individual insurers, without sales pressure. Brokerage commissions received from insurers are disclosed. Your insurance data flows automatically into your tax return as deductions. Actual savings depend on your individual situation.
