How to prepare and submit an authorisation application

An organisation’s representative can submit an authorisation application in the Suomi.fi service’s official-assisted authorisation service. The recommended way is to use the service’s web form.

You can check beforehand what attachments you need for an authorisation application. Based on the information you have given, you will receive a completed authorisation application for signing, a list of the documents required for the application and instructions on how to submit the application for processing.

You may need to attach documents to your application to indicate that the signatory has the right to sign the application and that the authorisation granted meets the assignor’s requirements.

Remember to sign the application. You can print the application and sign it by hand or use an electronic signature. Depending on the assignor, the authorisation application can be submitted for processing online, by post or by visiting a tax office.
