Test submission of SAF-T Regnskap (Financial) and SAF-T Kassasystem (Cash register)

We recommend that all developers of solutions that support the SAF-T formats take part in testing. By participating, you can test validation of the file format and receive feedback on the content.

To help ensure the highest possible quality of SAF-T files, we review submitted SAF-T test files. We check that the information in the files is consistent.

For SAF-T Financial, we check, for example, that all VAT codes (<TaxCode>) used in transactions (GeneralLedgerEntries) are defined in the VAT code list (MasterFiles\TaxTable).  

For SAF-T Cash Register, we check, for example, that all event types (<eventType>) used in the events section (<event>) are defined in the list of non-sales events (Event codes) in the basics section.

Test the file format yourself

Before submitting a SAF-T test submission, we recommend that you validate the file format yourself. Several validation tools are available for this purpose. The Tax Administration has developed a validator for testing the file format (Github).

You can send SAF-T test files by email to:

[email protected]

If a test submission consists of several files, you can send them together in one email. Each test file can be up to 15 MB, and a test submission can contain up to 10 files. 

We only accept XML files as email attachments.

We do not accept .zip files.

SAF-T files must contain synthetic data 

The files submitted to the Tax Administration’s test environment must contain synthetic data to protect privacy.

Synthetic data is artificial data that is not based on real data. It must not contain information that can identify individuals or businesses. Examples of identifiable information include organisation numbers, national registration numbers, addresses, telephone numbers, and similar information.

Files that contain data other than synthetic data will not be processed.

After we have reviewed your test file, we'll send feedback by email.

If you want the feedback in english, please inform us when submitting the SAF-T files.
