Service numbers

If you fail to take care of your tax matters in MyTax or if you have any questions, you can also send us a written message in MyTax.

When our service agents assist you on the phone in how to use the service, they can see your information in MyTax. Unfinished details will not be used in your tax assessment.

We will store your activities in MyTax so that we can investigate any faults or malfunction that may occur in the service. We will destroy the recordings after 30 days.

Taxpayers with a non-disclosure order – your information is in MyTax

If you have a non-disclosure order for personal safety reasons, MyTax shows the information covered by the order both to you and your authorised agent. At the Tax Administration, only named employees have access to the information.

In exceptional cases, a taxpayer service agent may see your contact details in a recording. The service agents are Tax Administration employees and bound by confidentiality.

Documents are stored in MyTax for a limited time

We keep documents in MyTax only for as long as we need them for tax assessment. If you need the documents for other purposes, save them on your computer or in some other way.
