How to use MyTax for your tax matters
These instructions help you to log in to MyTax, navigate the service and get an overall idea of the process of filing a tax return, for example.
You need
- a computer, a tablet or a smartphone and access to the internet – check what devices and browsers are recommended for MyTax
- personal online banking codes, a mobile certificate, a certificate card, or the Finnish Authenticator app (foreign companies)
- the information you wish to report to the Tax Administration.
Proceed stage by stage
Logging in to MyTax requires electronic identification, which means that you need personal online banking codes, a mobile certificate or a certificate card. Foreign companies can use the Finnish Authenticator app. In practice, logging in to MyTax is like logging in to your own online bank.
