What "SAF-T (Standard Audit File for Tax)"

SAF-T is an international standard for the electronic exchange of reliable accounting data from organisations to a national tax authority or external auditors. It covers master data, general ledger entries, sales and purchase invoices, payments, and inventory movements.

1

What the SAF-T file actually contains

SAF-T is not a summary; it is a detailed data export. Any inconsistency between your operational modules becomes immediately visible to the tax authority.

  • Master Data: partners, products, chart of accounts, units of measure, and VAT rates.
  • Transactions: issued and received invoices, including line items and tax references.
  • Payments and receipts, mapped directly to the original source documents.
  • Inventory: stock movements and, where applicable, fixed asset registers.
2

Common data mismatches in tax reporting

Discrepancies usually stem from data being entered twice across separate systems with conflicting validation rules.

  • Credit notes issued without a clear reference to the original invoice.
  • Payments that are unallocated or matched to different documents than in the accounting record.
  • Inconsistent units of measure between warehouse management and billing.
  • Duplicate partner profiles or invalid VAT registration numbers.

How CRMconnect streamlines audit preparation

Documents are generated from a single source of truth: credit notes maintain mandatory references, payments are reconciled daily via bank statements, and master data is validated. Data arrives in the accounting software (such as SAP Business One or Microsoft Dynamics 365) already correlated, turning tax filing into a verification task rather than a reconstruction project.
