Swiss VAT

Please note this module is experimental. Make sure to verify your data.

The Swiss VAT module for Dolibarr allows you to produce your VAT return for the Swiss Federal Tax Administration (AFC/ESTV) without leaving your management software.

Based on your validated customer and supplier invoices, the module automatically calculates all figures of the AFC form (lines 200 to 910) according to the VAT method configured for your company.

Three reporting methods supported:

• Effective method: calculation of collected VAT by rate (8.1%, 2.6%, 3.8% — and pre-2024 rates: 7.7%, 2.5%, 3.7%) with deduction of input tax on supplier purchases.

• Net tax rate method (TDFN): application of the TDFN rate specific to your activity on taxable turnover, according to AFC schedules.

• Flat tax rate method: same principle as TDFN, using flat rates applicable to each industry sector.

Key features:

• On-the-fly calculation from validated invoices — no manual entry, no intermediate storage.

• Flexible period selection: free date range or predefined shortcuts matching your declaration frequency (monthly, quarterly, semi-annual, annual).

• Full AFC form display with all numbered lines (200 to 910).

• XML export in eSWST format for direct import into the AFC ePortal.

• UID number and AFC VAT number automatically retrieved from the Dolibarr company profile.

• Support for historical VAT rates (before 01.01.2024) on older invoices.

• Accessible from the Accounting and/or Invoicing menu depending on active Dolibarr modules.

The module is designed for Swiss VAT-registered companies that manage their invoicing in Dolibarr and want to prepare their AFC return without re-entry or third-party tools.
