MyTax will be down during the weekend – manage your taxes is good time
Tax Administration Bulletin, 11/9/2026MyTax will be down from Friday evening to Sunday evening on 13–15 November. During the downtime, you cannot manage your taxes in MyTax. For example, you cannot request a new tax card or pay your taxes. If you have any tax matters to manage, do it in good time before the downtime.
The downtime is due to an annual system update. During the update, usability improvements will be made and new functionalities added to MyTax.

Why is the system update needed, and will MyTax change?
After the update, MyTax will look the same as before. During the downtime, some usability improvements will be made and new functionalities added to MyTax.
One of the most notable changes following the downtime is that you can submit annual information returns by acting on behalf of a company in MyTax. The change concerns annual information returns on dividends, for example.
Also parties requesting tax-at-source refunds can do so in MyTax in future. Further, information on the first registration of new vehicles will be introduced into MyTax, where registered filers of car tax can use it.
Nonprofit corporations will find an updated application for tax relief for corporations in MyTax. The updated application will include more detailed questions about the corporation’s activities. In addition, the corporation’s rules, operations plan and budget will need to be attached to the application. The objective of the change is to cut the number of information requests and simplify the processing of applications.
Moreover, the system update also helps us prepare for future changes. More information: vero.fi/changes
