MyTax

MyTax is the Tax Administration’s e-service for most of your tax matters.

You can log in with your online banking codes, a mobile certificate, or a Katso ID. If you wish to act on behalf of someone else, you will need authorisation. You can no longer use Katso IDs and Katso authorisations after 31 August 2021.
