Context
SAF-T D406 = Standard Audit File for Tax required by ANAF (the Romanian tax authority) on a monthly or quarterly basis. All three Socrate products natively generate XML files compliant with the XSD schema.
Monthly Workflow
25th of the current month: Partial closing + pre-validation.
Days 1-3 of the following month: Finalizing ledger entries.
Days 5-7: Data validation (Chart of Accounts, nomenclatures).
Days 10-15: D406 XML generation + XSD schema validation.
Days 20-25: Submission via the SPV (tax authority portal).
Critical Validations
Chart of Accounts mapped to the official tax authority plan
Partners with complete VAT ID (CUI)/name/address details
Items with proper code/description/UCUM units of measure
All monthly invoices balanced
Reconciled stock levels
Common Errors
1. Partner missing VAT ID — add a mandatory field validator.
2. Non-UCUM units of measure — use standard units.
3. Unmapped accounts — verify every time a new account is created.
4. Transactions without documents — every journal entry must have a reference.
5. Unbalanced stock — perform monthly inventory checks.
