Test Submitting

The Tax Administration offers all system suppliers or other developers of solutions to support the SAF-T format a chance to take part in testing via Altinn. 

Coordinate testing with the system supplier

Clients of system suppliers should not participate in the testing without coordinating with the system supplier. The reason for this is that the system supplier must handle any errors or discrepancies, and because the Norwegian Tax Administration cannot provide feedback such as confirming whether a mapping of chart of accounts has been performed correctly. 

How to take part

Timetable

The timetable gives a description on how to log in and send test data from Altinn’s test environment TT02 to the Norwegian Tax Administration.

Information on how to participate and submit SAF-T Accounting files and SAF-T POS system files for testing can be found in the timetable.

Test person

To participate in the test, you must have a test person. The Tax Administration has established a synthetic national population register that has been read into Tenor testdatasøk. Via the Tenor testdatasøk you can find the test person.

Reference number

The reference number to be used is 2023/5000002.

If you have any questions

Go to the contact form to send enquiries to the Tax Administration regarding the manual review of the test file. Mark your enquiry SAF-T Financial or SAF-T Cash Register. 

Requirements for test submissions 

Conditions for processing submitted test files

The file submitted to the Tax Administration's test environment must contain synthetic test data. Synthetic test data are artificial data, not based on real data. The file must not contain information that can identify the sender or any third parties, such as personal information. Files found to contain such information will not be processed and will be deleted. 

Activity 1 – Testing the file format for validation with the schema 

In order for the test submission to be successful, you must test the file format before submission in Altinn. There are several free validation tools available, and the Norwegian Tax Administration has developed a validator for testing the file format. 

When you submit files via Altinn's test environment, the files undergo file format validation. Please note that we do not provide comprehensive feedback for the different error types. 

Activity 2 – Submitting test data 

When the SAF-T XML file is validating, it can be submitted as test data to the Tax Administration via Altinn. 

The Tax Administration or system suppliers to the Tax Administration may use submitted test data for test purposes. For privacy reasons, the test submissions must contain only synthetic data and no sensitive information about the sender or any third parties. This means, among other things, that the following information elements must be synthetic:  

Information that must be anonymized

XML fields such as these from SAF-T Financial 

company names and information about companies   

<Name> and <TaxRegistration> 

addresses 

<StreetName> and <PostalCode> 

name of individuals 

<FirstName>, <LastName> and <AdditionalAddressDetail> 

contact information (e-mail, phone number, fax, etc.)  

<Email>, <Telephone> and <Fax> 

account numbers, IBAN-numbers etc. 

<IBANNumber> and <BIC> 

This overview is not a complete list. It only shows examples of the information type and field codes that must be anonymised. All information that can be linked to an individual or an impersonal legal subject must be removed from the files. 

In Tenor testdatasøk, you can retrieve test data that can be used in these xml fields.
