News on stakeholder testing

Schedule for tests of changed data content for 2026

The changes affecting the schema will be published for testing from 18 June 2025 onwards.

You can test the changes in the technical interfaces, the e-service and the upload service.

More information available on the Documentation page.

Interface's addresses will change during 2026

The IP addresses of the technical interface's test environment (EXT) of the Incomes Register will change next year. At the beginning of the next year, we will publish a new estimate of the timing of the change.

• If you use direct IP addresses on the interface, changes to the system will be required due to the change of address.
• If you use name-based IP addresses, the change will have no effect and no action is required.
