Four core capabilities — from receipt capture to cantonal filing.

AI Assistant · Receipt Scanner · e-Filing · English · All 26 Cantons

Avenzo combines the three capabilities that make Swiss tax filing faster and more accurate: intelligent deduction finding, automated document processing, and direct electronic filing with cantonal authorities.

AI Tax Assistant

The Avenzo AI assistant analyzes your personal situation — permit type, family status, canton, income sources — and surfaces every deduction you are entitled to, including canton-specific limits you may not be aware of.

What the AI finds:

• Professional expenses: commuting (CHF 0.70/km), meals outside the home (up to CHF 3200/year), professional training (up to CHF 12000)
• Pillar 3a contributions (up to CHF 7258/year for employees — fully deductible)
• Health insurance premiums (lump sum approximately CHF 2800 for singles, CHF 5600 for couples)
• Childcare costs (up to CHF 25500 per child per year for third-party care)
• Imputed rental value optimization (mortgage interest + maintenance cost deductions)
• Withholding tax (Quellensteuer) optimization for B permit holders
• RSU and stock option income allocation

The AI learns cantonal rules: deduction caps differ between Zurich, Bern, Aargau, and every other canton. You never need to look them up manually.

Receipt Scanner (OCR)

Point your camera at any Swiss financial document and Avenzo extracts the relevant numbers automatically:

Supported documents:

• Salary certificate (Lohnausweis — Form 11)
• AHV/AVS personal account statement
• Pension fund statement (Pensionskassenausweis)
• Pillar 3a certificate
• Bank statements (dividends, interest — Wertschriftenverzeichnis)
• Mortgage interest certificate
• Health insurance premium confirmation
• Donation receipts

Documents are processed using OCR (optical character recognition) and mapped directly to the correct tax fields. Scanned documents are stored encrypted on Swiss servers.

Direct e-Filing

Once your return is complete, submit it electronically to your cantonal tax authority — no printing, no postage.

How it works:

1. Avenzo generates the completed cantonal tax file in the correct format
2. You review and approve the return
3. Avenzo submits directly to the cantonal portal
4. You receive a digital confirmation of receipt

Cantons with full e-filing: Zurich (ZH), Bern (BE), Aargau (AG), Lucerne (LU), St. Gallen (SG), Zug (ZG), Basel-Stadt (BS), Solothurn (SO), and more.

For cantons without e-filing, Avenzo generates the correct PDF for manual submission, pre-filled with all your data.
