French VAT CERFA 3310-CA3 - VAT Return for Dolibarr

Professional French VAT return module (standard real tax regime) for Dolibarr. Automatically calculates your CERFA 3310-CA3 form from your customer and supplier invoices, with fiscal safeguards that block any inconsistent return before filing.

Features

• Full CERFA coverage: multi-rate (20%, 10%, 5.5%, 2.1%), reverse charge art. 283-2 (EU and non-EU services), intra-community acquisitions B2, exports E1, non-taxable transactions E2
• Fiscal safeguards at validation: 10 internal consistency rules R1-R10 (line 08 = base × 20%, base_08 = A1+A3+B2, line 16 = 08+09+9B, etc.) — inconsistent returns are blocked before filing
• Inter-period credit chain verified: line 22(N) = line 27(N-1), automatic propagation between quarters
• Accounting allocation pre-check: audit of 2xxx accounts (fixed assets) vs 6xxx accounts (expenses) before any CERFA calculation — zero classification error
• Assisted accounting allocation: automatic account suggestion based on the active chart of accounts (general or non-profit PCG), one-click application from the declaration form
• OSS option (One Stop Shop): below the €10,000 threshold, B2C EU distance sales remain under French VAT; activable for the One Stop Shop regime
