Electronic tax mail and e-mail address of companies in MyTax

What does ‘electronic tax mail’ mean?

It means that the Tax Administration letters, decisions on assessment, other decisions, other documents, etc. arrive in MyTax and are available there. No duplicates of these letters, decisions, etc. will be sent to your company in paper format.  If you have the right to sign for the company or if you are a holder of the Managing tax affairs mandate, you can type in your e-mail address in MyTax. After that, you will receive an e-mail notification whenever a new letter or other document has arrived for your company, to appear in MyTax.

When do I start receiving tax mail in MyTax only?

Corporate entities, partnerships, joint administrations of a benefit, or estates of deceased persons with a Business ID can refrain from receiving paper mail from 30 January 2026 onwards.  However, in certain situations, the Tax Administration might still send paper letters. For example, if the company is the client of an agent/representative managing the company’s taxes, paper letters will be sent.

If the “electronic tax mail” setting is already in place, there will be no change. However, it is important to note that whereas the MyTax field Delivery method for mail indicated the company’s e-mail address previously, it will now be under Email addresses of people managing taxes.

How to disable paper tax mail

If so far, your company has been getting all its tax mail on paper, you can make the following settings to start receiving electronic tax mail in MyTax:

1. It is required that you have the right to sign for the company or the Managing tax affairs authorisation.

2. Log in to MyTax and select Act on behalf of a company. 

3. If you have multiple authorisations for many client companies, a list will appear. Look up the company for which you want to disable paper tax mail.

4. After selecting the company, you will see the Welcome page. Now click on Submit a notification about cancelling paper tax mail and select: Give up paper mail. 

   Please note that if no e-mail addresses are saved among the taxpayer details, you cannot give up paper mail. In this situation, you need to go to the Taxpayer details tab to add an e-mail address – at least one – under Email addresses of people managing taxes. 

5. To receive notifications to your personal e-mail concerning the company’s letters, document, etc., make sure that your e-mail is saved among the Email addresses of people managing taxes (the Taxpayer details tab). The e-mail address format must be identical with the format saved in the MyTax section Your own details. If you have a limited authorisation, you cannot receive all notifications or information. 

   When your contact information is on MyTax, you will receive notifications of all the company’s events in MyTax.

   If you do not want the notifications, you can remove your e-mail address from the list on Email addresses of people managing taxes.

   To set notifications exclusively for some topics related to your company, make the selections in your e-mail software.  

6. When you have set the notifications, the changes will take effect immediately. The current settings for tax mail are on the Taxpayer details page under Delivery method for decisions and letters.

7. Note: tax mail is only sent to MyTax. No decisions, letters, etc. relating to taxes are ever e-mailed.

If you still have paper mail settings on, the Welcome page will be showing over and over again upon login. 

You are an accountant, and your client is a limited-liability company for which you deal with tax affairs. You need to submit the monthly VAT return. You log in to the company’s MyTax on 30 January or on a later date. After logging in, select Act on behalf of a company and select the company on the list.

Click on Submit a notification about cancelling paper tax mail and select: Give up paper mail. Type in your e-mail address on the Taxpayer details tab under Email addresses of people managing taxes.

Later, as the company’s managing director logs in to the company’s MyTax, the personal e-mail address of the managing director can be typed in as well. This way, the managing director would also get the notifications of any new tax mail.

A partnership operating a forestry enterprise has 3 shareholders. You are the only one among them with the Managing tax affairs authorisation mandate. Log in to MyTax and select Act on behalf of a company. Click Submit a notification about cancelling paper tax mail, and then – Give up paper mail. Type in your e-mail on Taxpayer details — Email addresses of people managing taxes.

• Please note that if no e-mail address is included in the partnership’s details, you cannot set the “give up paper tax mail” setting. If there is no e-mail address, you need to go to the Taxpayer details tab to add an e-mail address – at least one – under Email addresses of people managing taxes. 

The above settings and changes will take effect immediately. The Tax Administration will send notifications when the forestry partnership has got new tax mail, delivered electronically only and not duplicated on paper. If convenient, you may want to log in to MyTax to give the e-mail addresses of each shareholder so that everyone could get the notifications about new tax mail for the forestry partnership.

However, only you can read the tax mail because only you have the mandate “Managing tax affairs”.

Make sure to update your e-mail information in MyTax

When you have the right to sign for the company or when the Managing tax affairs authorisation is issued to you, you can add and delete e-mail addresses on the company’s Taxpayer details tab.

It is important to have an e-mail on record in MyTax, because the Tax Administration will send notifications on new letters, decisions, etc. to MyTax. With no e-mail address on record, you would learn about new tax mail only when you log in.

The company has the responsibility for keeping its e-mail addresses up to date. Make sure that your company only has the e-mails listed that are relevant for getting notifications about new mail. You need to delete any unnecessary e-mail information yourself. Make sure to update the addresses especially when the persons in charge of a company (association, foundation, other corporate entity) change their jobs and responsibilities.

Updating e-mail addresses

1. Log in to MyTax.

2. After logging in for the company select the Taxpayer details tab.

3. Go to Email addresses of people managing taxes and click the Update email addresses button.

4. Add or change the e-mails as appropriate. Remember to remove any e-mail address from the list before an authorisation mandate, a right to manage your company’s taxes has ceased to be valid. Remember to remove the address also if anyone ever wants to stop receiving the notifications. After you add or remove an e-mail, the Tax Administration will send you a message to acknowledge the changed settings.

5. After an added e-mail address has been recorded, the person being the recipient will start getting notifications on all tax-related issues that concern the company.

Having an authorisation mandate for a company

When you have the “Managing of tax affairs” authorisation and you act on behalf of a company, association, foundation, partnership, benefit or estate, the tax mail will only be available in MyTax if you or other authorised parties have chosen to give up paper tax mail.

However, if you have the “Managing of tax affairs” authorisation and you act on behalf of a self-employed individual, agricultural operator or forestry operator, you cannot make the electronic tax mail selection. For further instructions regarding the self-employed, forestry, and agriculture, see: Suomi.fi messages and electronically provided tax mail — individual taxpayers

If the company needs to receive tax mail on paper, you can submit a request to start receiving the company’s tax mail on paper. You can do that on MyTax, on the Taxpayer details tab.

Operator of business (T:mi), agriculture or forestry: Use “Manage your tax matters” on MyTax to take care of all of your taxes. This also applies even if you have given yourself a "Managing of tax affairs” authorisation mandate. You may have given the mandate when representing your company and its Business ID on Suomi.fi. However, if you have the “Managing of tax affairs” mandate for a corporate entity or limited company, etc., the Act on behalf of a company should be used instead.

If you have an authorisation other than the “Managing of tax affairs” authorisation that allows you to log in to MyTax, you cannot change the delivery method of the company’s tax mail. In the same way, with a limited authorisation, you cannot see or edit the e-mail addresses recorded on the company’s taxpayer details. However, a person who has a stronger authorisation can add your e-mail to the company’s details if necessary. After that, you will get notifications about the company’s all tax matters while you would still not see all the related content in MyTax.

If the company has a tax representative whom the Tax Administration has registered, they will always receive paper mail.

If the company needs to receive tax mail on paper, although a holder of an authorisation mandate keeps managing company taxes in MyTax, the holder of the mandate can select “tax mail on paper”, providing that the type of his or her mandate is “Managing tax affairs”. 

When you relinquish a previous authorisation or rights related to a client company

An end date of a period of validity of an authorisation will not halt your e-mail notifications. This means that you (or someone else who holds an authorisation mandate) and the company must make sure the list of e-mail addresses on the company’s taxpayer details gets updated.

If you have held authorisation(s) and the period of validity is ending, follow the instructions below:

1. Log in to MyTax, go to Taxpayer details, and delete your personal e-mail address on the list.
2. The Tax Administration will send you an e-mail to inform you that the address is no longer included in the company's details.
3. After this, you will no longer receive notifications for the company concerned.

After your authorisations or rights have ceased

If you are no longer authorised to act on behalf of a certain company, you cannot make changes to its notification settings in MyTax.

The only person who can make the necessary updates will be someone who has the right to sign for the company or the Managing tax affairs authorisation mandate. That person can delete your personal e-mail address from the company’s Taxpayer details.

Moving back to paper tax mail

If the company prefers paper letters from the Tax Administration, a person who has the right to sign for the company or has the Managing tax affairs mandate should file a notification about selecting tax mail on paper. This can be done on the Taxpayer details tab in MyTax. 

How to find decisions and letters

1. Go to MyTax and log in if you are not logged in yet (a new window will appear)

2. Select the Communication tab.

3. Under Decisions and letters, select Open decisions and letters.

4. ll the decisions and letters you have received during the past 12 months are listed on the page.

5. To find decisions and letters that are over 12 months old or that have been opened or archived, use the search function.

6. The search will return all the tax decisions issued to the company.

Letters related to tax audit reports in MyTax

1. Hearing on the tax audit report
2. Summary of the tax audit report
3. Tax audit report
4. List of findings of the tax audit report.

After the hearing, you will receive a new set of letters in MyTax:

1. Decision on adjustment of income tax, tax audit
2. Decision on self-assessed tax, tax audit
3. Summary of the tax audit report
4. Tax audit report

On the Tasks tab in MyTax, you can see your current matters, such as:

• You have received a new decision or letter in MyTax.
• We need more information from you for tax purposes.
• Information about alternative ways of taking care of tax matters, such as the use of e-invoicing.

When you click a task, MyTax will move you directly to the correct section. After that, the task is no longer shown on the Tasks tab.

Delete and restore tasks

If you want to delete a task shown on the Tasks tab, click the X next to it.
