Standard Audit File for Tax (SAF-T)

Standard Audit File for Tax (SAF-T) is an international standard for electronic exchange of accounting data from organisations to a national tax authority or external auditors.

Revenue bodies have for many years conducted tests on accounting records in order to be assured that business tax obligations have been met. Globalisation of the world economy, including the emergence of electronic commerce, has created a new environment in which multi-national businesses are subject to a number of different legislative requirements around the world. Revenue bodies also see an increased need for international cooperation through the exchange of information and, where appropriate, multi-jurisdictional audit.

SAF-T has been designed to allow auditors access to data in an easily readable format for substantive testing of system controls and data, using proprietary audit software, as part of a methodology that also provides increased effectiveness and productivity in computer-assisted audit. SAF-T is intended to be suitable for use by businesses and their auditors across the scale from Multi-National Enterprises (MNEs) to Small to Medium Enterprises (SMEs).

SAF-T has been implemented across many countries in the OECD including Portugal, Luxembourg, Austria, Poland, Lithuania, Norway & France with others to follow.

SAF-T has been designed to capture data from a number of areas found in a typical business accounting system such as:

  • General ledger journals
  • Customer and Supplier master files
  • Customer and Supplier Invoices
  • Customer and Supplier Payments
  • Fixed asset master files
  • Depreciation & revaluation
  • Product master files
  • Inventory movements


XML Authority’s schema library contains SAF-T XML schema implementations for different European jurisdictions, including.

  • Luxembourg Tax Administration (Administration de l’Enregistrement et des Domaines (AED)).
  • Austrian Ministry of Finance / Bundesministerium für Finanzen
  • Norwegian Tax Administration / Skatteetaten
  • Polish JPK (Serwis Rzeczypospolitej Polskiej) 

Other implementations will be added as they become available.

SAF-T User Interface


XML Authority’s intuitive user interface makes producing valid Standard Audit File for Tax (SAF-T) XML filings easy with little or no training.

The user guide provided by the OECD can be difficult to interpret.  Using XML Authority’s simple presentation of the schema as a set of forms and tables, a detailed understanding of the data requirements can be gained at a glance.


Reports can be further simplified by eliminating non-relevant sections using the Schema Masking functionality.

Easly hide non-mandatory elements (individual reporting elements or entire report sections) which not only simplifies the schema layout but also reduces the complexity of your required import data.

Integrate to Data in Excel or Relational Database


Save time and reduce errors by importing data from XML Authority generated Microsoft Excel import templates or linking to data in relational databases.

Create a set of related tables from which to read data which conform to the Standard Audit File for Tax (SAF-T) schema using database scripts generated by XML Authority itself.


Be assured that your data is in compliance with the requirements of the schema through XML Authority’s validation functionality.

Get real-time feedback on the validity of data input and use the interactive Validations panel to help find and navigate to issues which would cause rejection at your local Tax Authority’s submission gateway.
