The payment and payment agreement services will not be available from 12:00 on 31 December to 10:00 on 5 January
You cannot pay, defer, or split your claim in this period.
As of 1 January 2026, new debt collection rules will take effect and several collection authorities will be merged into one: the Collection Authority in the Tax Administration. This means that we are:
- phasing out sismo.skatteetaten.no and moving all the content to skatteetaten.no
- rebuilding and updating skatteetaten.no for a few days from and including 1 January
