MyTax is the Tax Administration’s e-service, where you can take care of most of your tax matters.
You can log in to MyTax 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. Read more about authorisations
Tax cards for 2019 are not yet available in MyTax. You will receive your 2019 card on paper by post. Log in to MyTax when you have your tax card to make changes to it, from 13 December onwards.
