Suomi.fi messages and electronically provided tax mail – individual taxpayers

If you are of legal age and Suomi.fi messages have not been actived for you so far, you will have them activated automatically upon e-identification through the online login sequence on Suomi.fi. The Suomi.fi login sequence is the usual way you log in to MyTax or to another public authority’s e-services (OmaKanta, OmaKela, and others). 

• An automatic process will create an inbox for you as you log in.
• Suomi.fi Messages is an e-service of the DVV, the Finnish Digital Agency. You will receive letters, documents, decisions, invoices, etc. from Finnish public authorities in electronic format. No duplicates will be sent on paper.
• You can read the letters, etc. on Suomi.fi through a mobile app and on the secure suomi.fi/messages pages on the web. You can download the free app.
• Suomi.fi Messages will notify you of a new letter if you have added your email address to your personal data stored by the e-service or into your Suomi.fi app (with the setting “Allow notifications”).

However, you can always find the tax-related letters, decisions and other documents sent by the Tax Administration in MyTax – they will not go to Suomi.fi. 

The notifications coming to your inbox on Suomi.fi are for information, to tell you that you got mail. Your tax-related mail will appear in MyTax only.

Note: You will automatically start receiving official correspondence in electronic format when you log in to any public e-service through Suomi.fi. After that, the majority of the correspondence will be delivered electronically only, in Suomi.fi Messages.

When you log in to MyTax on 1 June 2026 or later and you select Manage your tax matters, you become a recipient of electronic tax mail. Then you will get your letters, decisions, etc. from the Tax Administration only in MyTax. No duplicates will be sent to you as paper letters by post. Although you might have declined the Suomi.fi Messages functionality, you would get your tax mail to MyTax because you use MyTax to manage your taxes. 

Please add your email address or phone number to your personal details in MyTax to receive notifications whenever a new letter, decision, etc. is appearing for you in MyTax.

Informing the Tax Administration of your e-mail or phone

1. Log in to MyTax and select Manage your tax matters.  
2. The Welcome page will appear. Click Submit contact information for tax mail to type in your information.   
3. Type in your email address or telephone number – or both. When you have a new decision or letter in MyTax, the Tax Administration will use the saved contact information to send you a notification. You have the option to decline to give out your email and phone number. In that case, you will not receive the notifications about new tax mail coming to MyTax.  
4. If you type in a phone number, a question will appear: “Do want to update the phone number of your personal details in the Tax Administration’s database?” Answer Yes or No as appropriate. If your answer is Yes, and some time later in the future, further information would be needed for your tax assessment, the Tax Administration would use this phone number to contact you. In general, the phone number is for the following purposes:
   • The phone number will automatically be inserted into your tax returns, forms, claims for adjustment etc. that you submit in MyTax.
   • Tax officials can call you on the phone number.
   • The Tax Administration can send text messages to the phone number.
5. You will no longer receive paper letters from the Tax Administration. When you have new tax mail in MyTax, we will send a notification. We will use the contact information you gave.
6. You can submit more than one email address to be saved by MyTax. For example, if you want a member of your family, or someone else, to receive notifications about new tax mail, you can add their e-mails into Email addresses of people managing taxes on the Taxpayer details

The above changes will take effect immediately. 

Note: If your Suomi.fi Messages are enabled, a message transmitted through Suomi.fi will always inform you of a new letter. If you type an email address and/or phone number in MyTax, you will also receive notifications by email and/or SMS from the Tax Administration – concerning the same new letter. This means that you can receive multiple heads-ups for your information.

You can authorise another person to manage taxes and tax mail on your behalf. This might be useful if you are uncomfortable with electronically provided services. You can give a family member an authorisation on Suomi.fi.

Instructions: Suomi.fi authorisations for taxes – how to grant and request authorisation

Do not let a family member use your e-bank security codes. Instead, you should give them an electronic authorisation. The authorisation is much more secure. The authorisation mandate called Managing tax affairs means that the family member will always enter their personal e-bank security codes – not yours – into the MyTax system. With the Managing tax affairs mandate, he or she can deal with your taxes and read your tax letters or tax decisions, etc. that you receive.

After you give the Managing tax affairs mandate to someone, you will continue to have the same rights as before. In the same way, you will also continue getting your tax mail on paper if you have received the letters, decisions, etc. on paper before – or alternatively, you will continue to receive them in electronic format if you have received them electronically so far. The Managing tax affairs mandate provides an opportunity to the other person to deal with a tax issue of yours when needed.

Another mandate you might consider giving someone is a permission for utilising Suomi.fi messaging on your behalf. Instructions on Suomi.fi: Acting on behalf of another person, using messages.

Do not borrow the family member’s personal e-bank security codes. Instead, you should ask for an electronic authorisation to manage taxes. The authorisation is much more secure. After your family member signs in to Suomi.fi to give you the Managing tax affairs authorisation mandate, you will be entitled to see the family member’s MyTax account. You log in to MyTax with your e-bank security codes, not theirs. This way, you get to read any letters or decisions the Tax Administration has sent, and you can deal with the family member’s taxes.

You can have your personal email address saved on the family member’s MyTax, on the Taxpayer details tab – Email addresses of people managing taxes. When your family member’s MyTax account has your email, you will be receiving the notifications concerning new letters, etc. that the Tax Administration sends to the family member.

Even if you save the above settings and start receiving these notifications to your own email, it will not affect the way your family member will receive letters from the Tax Administration. This means that the family member’s mail settings would only be changed to electronic if he or she logs into MyTax with a personal means of electronic identification such as e-bank security codes or a mobile certificate. 

In the event that you don’t have Suomi.fi Messages activated, an automatic process will activate them for you when you log in to MyTax. You get an electronic mailbox for Suomi.fi Messages and you will also receive your own official correspondence electronically.

When you have the Managing tax affairs authorisation mandate, you can use MyTax on your family member’s behalf to select tax mail on paper, if needed. After that, your family member will always receive the letters on paper.

How to enable paper tax mail

1. Log in to MyTax and select the person on whose behalf you are changing the settings.
2. Go to Taxpayer details — Notification about selecting tax mail on paper.
3. To answer the question “Do you select tax mail on paper?”, select: I confirm that I select tax mail on paper.

In the event that the person who authorised you has passed away, the selection will be changed to paper. All the e-mail addresses will be removed, which during the person’s lifetime were listed under “Email addresses of people managing taxes”. This means that none of the people managing taxes nor you will get notifications regarding the deceased person’s taxes.

If you are under 18, you receive your tax mail on paper. To change the settings to electronic delivery, you can activate Suomi.fi Messages if you have a Finnish personal identity code and e-bank security codes or another personal identification method, a mobile certificate, etc.

When Suomi.fi Messages is activated, you will get all the correspondence from public authorities in electronic format. Because you are under 18 you cannot yet submit the contact information needed for receiving your tax mail in MyTax.

As the parent or guardian of a child under 18, you can type your personal email address into MyTax to start receiving notifications from the Tax Administration about new tax mail addressed to your child. Type in your email on the Taxpayer details tab, under Email addresses of people managing taxes.

Persons whose age is under 18 will always receive paper post if they do not have Suomi.fi Messages enabled.

Being the parent or guardian, you can also change the Suomi.fi Messages settings on your child’s behalf. Instructions on Suomi.fi: Acting on behalf of another person, using messages.

In the event that you don’t have Suomi.fi Messages, an automatic process will activate them for you when you log in to MyTax. You get an electronic mailbox for Suomi.fi Messages and you will also receive your own official correspondence electronically.

Private guardians and attorneys always receive the principal person’s tax mail on paper. However, you can submit your own email address when you use MyTax, to receive a notification whenever the principal person gets a letter, decision, etc. to MyTax. Add the email address on the Taxpayer details tab, under Email addresses of people managing taxes.

If your principal person – who is under your guardianship – has Suomi.fi Messages activated, he or she will be notified via Suomi.fi when a letter is sent to you who are their guardian.

In some circumstances, a private guardian has an automatic right to use Suomi.fi on the principal person’s behalf. Instructions on Suomi.fi: Guardianship.

If you have had Suomi.fi Messages and/or electronic tax mail on for some time, but you want to receive paper letters from the Tax Administration and other authorities again, you need to submit one or both of the two requests described below, depending on your circumstances.

After 365 days, you will receive the correspondence electronically again if you log in (to any public e-service) with your personal e-bank security codes or with other personal e-identification.
