Avenzo handles VAT registration with the FTA (ESTV), quarterly returns, and the choice between the effective method and the flat rate method (Saldosteuersatz).

Company Formation — GmbH and AG

Starting a business in Switzerland requires notarization, commercial register entry, and share capital deposit. Avenzo manages the entire process:

GmbH formation steps:

1. Draft articles of association and bylaws
2. Capital deposit (minimum CHF CHF 20'000 for GmbH; CHF 100,000 for AG)
3. Notarization
4. Commercial register entry (Handelsregistereintrag)
5. VAT registration (if applicable)

Payroll (Lohnbuchhaltung)

For businesses with employees: monthly payroll processing, social insurance filings, and salary certificates for the annual tax return.

• AHV/ALV/UVG/KTG social insurance declarations
• Annual salary certificates (Lohnausweise)

Estate and Inheritance Planning

When a family member passes away, tax and legal obligations arise quickly. Avenzo's fiduciary advisors assist with:

• Inheritance tax return (cantonal — each canton has its own rules)
• Estate inventory and asset allocation
• Tax optimization for gifts and advance inheritance payments
• Property transfers and real estate capital gains tax (Grundstückgewinnsteuer)

Early planning can significantly reduce the inheritance tax burden on the estate.
