Tax deduction cards for employers
Modernising the tax deduction card service for employers
The Tax Administration is developing new APIs for payroll systems to provide tax deduction cards to employers. These APIs will replace the current integration with the Altinn form RF-1211.
Usage pattern
The useage pattern will remain the same as before; one API for ordering the tax deduction cards, and one API to retrieving the response. In the future, it will also be possible to listen for changes in the dialogue portal and retrieve the response using an ID from there.
The existing solution via RF-1211 will remain available in parallel with the new APIs. This means, for example, that you can order tax deduction cards using the old solution, and then order changes using the new one. There is also nothing preventing you from retrieving tax cards using the old solution even after having retrieved them using the new one.
Altinn II will close on June 19, 2026 - services must be discontinued no later than May 31.
Timeline
The APIs are now ready in both test and production.
