Report structure
The report is organized in two frames, in accordance with the CA3 form:
Frame A -- Amount of transactions carried out
Taxable transactions:
- Line A1: Sales, services
- Line A2: Other taxable transactions
- Line A3: Purchases of services (reverse charge art. 283-2)
- Line A4: Imports (excluding petroleum products)
- Line A5: Imports of petroleum products
Non-taxable transactions:
- Line E1: Exports outside the EU
- Line E2: Other non-taxable transactions
- Line E3: Distance sales taxable in another Member State
- Line F2: Intra-Community supplies
- Line F6: Purchases under franchise
- Line F8: Non-taxable adjustments
Frame B -- VAT payable breakdown
Gross VAT (by rate):
- Lines 08, 09, 9B, 10, 11: Standard rates (20%, 5.5%, 10%, 8.5% DOM, 2.1%)
- Lines T1 to T7: Specific DOM and Corsica rates
- Lines I1 to I6: VAT on imports
- Line 16: Total gross VAT due
- Line 17: Of which VAT on intra-Community acquisitions
- Line 18: Of which VAT on transactions destined to Monaco
Reverse-charged VAT on an intra-Community purchase (line B2 of frame A) is taken up in the corresponding rate line, 08 for 20%. The module reads it on the reverse charge entry at credit, whichever account is used: a 4452, a 4457, the account set in Dolibarr or the one from the import reverse charge dictionary. The rate comes from the account when it carries it, otherwise from the invoice line, otherwise from the product, as Dolibarr's purchase journal does.
Lines 17 and 18 are "of which" lines: they detail part of line 16 and are not added to it. A customer established in Monaco is treated as a French customer: its sales go to A1 and to the rate line, and their VAT is taken up in line 18.
Deductible VAT:
- Line 19: Deductible VAT on fixed assets
- Line 20: Deductible VAT on other goods and services
- Line 21: Other VAT to deduct
- Line 22: VAT credit carry forward
Result:
- Line 25: VAT credit
- Line 28: Net VAT due
- Line 32: Total net to pay

Detail by country
Each line of frame A shows the detail by country in sub-lines. This allows checking the geographic breakdown of transactions.
Totals check
The report includes a control section that compares:
- The frame A total from the ledger
- The total of invoices transferred to accounting
- The total of all invoices of the period
A difference signals invoices not yet transferred to accounting.
Warnings
The report automatically detects some configuration anomalies:
- Constant
ACCOUNTING_FORCE_ENABLE_VAT_REVERSE_CHARGEnot enabled - Reverse charge accounts not configured or not existing in the chart of accounts
- Foreign supplier invoices without reverse charge enabled (a supplier established in Monaco invoicing French VAT is not flagged)
For the last case, the warning indicates the correction to apply depending on the invoice status:
- Invoice not yet transferred to accounting: tick "VAT reverse charge" on the invoice before transferring it
- Non-EU invoice already transferred: generate the missing entries from Import VAT reverse charge. A direct link to this page is offered in the warning. No need to transfer the invoice again, Dolibarr only offers non-allocated invoices for transfer
- Intra-Community invoice already transferred: delete the invoice's entries in the ledger, cancel its allocation, tick "VAT reverse charge", then transfer it again
The warning disappears as soon as the invoice carries a reverse charge entry in the ledger, whichever credit account is used (4452, 4457, account configured in Dolibarr or account from the import reverse charge dictionary).
