You are required to report the rental income that you receive from renting out agricultural fields or other farmlands, forest lands, and items of property classified as other rental property. Examples of ’other rental property’ include a car, a boat, etc. that you have rented to someone. Submit the information in MyTax if possible. If you cannot use MyTax, you can use a paper form or authorise another person to act on your behalf.
If you co-own the property, you only need to report your share of the rental income and any associated costs (this may be the case if you and your husband/wife are co-owners).
For a tax partnership that receives rental income relating to agricultural farm or forest lands, the form for reporting the income is Form 2Y.
Choose your filing method
Note that there are no numbered forms, such as Form 7L, in MyTax. Report rental income on your pre-completed tax return or tax card request.
Send the form back to the address printed on it.

The online authorisation mandate
You can use the feature called “Suomi.fi Authorization” to enable you to deal with another person’s taxes through e-services, over the telephone, or by visiting a service point on their behalf.

Letters of authorisation on paper
You can receive a letter of authorisation from the other person. It will enable you to deal with that person’s taxes on the telephone, by visiting a service point on their behalf, or by submitting information on paper tax forms. To have a letter of authorisation (often called a ‘power of attorney’) does not provide access to MyTax.

When is there no need for an authorisation mandate?
The following circumstances are examples of when you can deal with someone else’s taxes with no authorisation.
You have child younger than 18 and you handle the child’s taxes
You are automatically authorised to access MyTax for the child, without an authorisation. Log in to MyTax and select “Act on behalf of someone else”.

You are a guardian
You do not need a Suomi.fi authorisation when your continuing power of attorney for being a guardian is officially confirmed, or when you are registered as a private guardian. Log in to MyTax and select “Act on behalf of someone else”.
Note: If you are a public guardian, in other words, a public official employed by a public guardianship office, you can only use paper forms.
