Technical documentation
You’ll find technical documentation for the tax deduction card service for employers, information on how to test your system, and other useful tips here.
We’re working with the migration of the tax deduction card service for employers from Altinn to separate forms and API solutions. Read more about the migration of the Tax Administration’s services from Altinn to Skatteetaten.no.
During a transition period, you’ll find two different solutions for the tax deduction card service for employers via an end-user system:
The Tax Administration is developing a new API for providing tax deduction cards to employers. You can find more information about this at GitHub:
Tax deduction cards for employers (GitHub)
Please note that the documentation about the migrated services is under development and is updated continuously.
Here you’ll find copies of the documentation that was located in the end-user system portal at Altinndigital:
- forespoerselomskattekorttilarbeidsgiver_v2.0.xsd
- eksempel_forespoerselomskattekorttilarbeidsgiver.xml
- skattekorttilarbeidsgiver_v3.0.xsd
- utvidelseavtrekktabellene2025.pptx
To integrate the system with the Altinn form you’ll need an XSD that’s found at the Register of Reporting Obligations of Enterprises (Brønnøysundregistrene).
