Real estate tax return (Form 3743e) – instructions for filling out the form

You can use the real estate tax return to correct or make additions to the information used as the basis for the real estate tax decision.

You can provide the information using either the MyTax service or this form. The form and further information are available on the Forms page. The return address is marked on the first page of the form.

If you are giving details on more than one real estate unit, piece of land or building, fill in a separate form for each one

Please note that the information you have entered on the form will be read by computer, by optical character recognition, and it only processes the text entered inside the form fields. Do not write anything in other areas, such as the margins of the form, because such information will not be processed.

If the real estate unit has multiple owners

If you are a co-owner of real estate, a piece of land or a building, together with your spouse, or if both of you have the right of possession, it is enough if you only submit one form under the name of one spouse.

Please note, however, that a cohabiting partner is not usually considered a spouse for tax purposes. A return filed together with a cohabiting partner is sufficient only if you have previously been married to each other, or you have or have had a mutual child.

If the real estate, piece of land or building also has other owners, they must report the information on their own forms.

1 Taxpayer identification and the tax year

Always fill in this section. Also fill in your personal identity code or Business ID and the tax year on the other pages of the form.

Name and personal identity code or Business ID

Name and personal identity code or Business ID of the party submitting the real estate tax return.

Tax year

The tax year respective to the information you are reporting. You can see the tax year on the front page of the real estate tax decision.

In real estate taxation, the tax year refers to the year for which the real estate tax is to be paid. Real estate tax is imposed on the party that owns the real estate unit or is an administrator equal to the owner at the start of the tax year, i.e. on 1 January (for further details, see section 3 of the instructions for filling in the form). In real estate taxation, the taxable value is determined based on the situation on the last day of the previous calendar year. This taxable value is calculated as based on the situation on the last day of the year (31 December).

Example: If you own a real estate unit on 1 January 2020, you will receive the real estate tax decision for the tax year 2020 in the spring of 2020. It is based on the taxable value of the real estate unit on 31 December 2019.

2 Identifying data pertaining to the real estate unit

Always fill in this section.

Property identifier

The property identifier of the real estate unit whose information you are reporting. A property identifier is a series of numbers divided into four sections, e.g. 092-416-0011-0123. You can find the property identifier on the real estate tax decision, the certificate of title or the deed of sale.

Parcel code

If you are reporting changes in the details of a non-subdivided parcel, please enter the parcel code that follows the property identifier. The format of the code is M0000. The property identifier of a parcel is a series of characters divided into five sections, e.g. 092-416-0011-0123-M0601.

3 Ownership and possession of the real estate unit on 1 January this year

In this section, you can correct information related to the ownership or possession of a real estate unit. State here if the real estate tax decision has not taken into account that, before January 1 of this year, you have, e.g.:

• purchased a real estate unit
• received a real estate unit as an inheritance, gift or other similar manner
• transferred the real estate unit.

Real estate tax is imposed on the party that owns the real estate or is an administrator equal to the owner at the start of the tax year (1 January).  An administrator equal to the owner refers to a person with a gratuitous right of possession to the real estate unit. Such a right of possession is created when, for instance, the real estate unit is given as a gift and the donor maintains the right of possession to the real estate unit. Read more about the right of possession.

If the real estate unit was sold during the tax year, the real estate tax for the whole year is imposed on the seller. Sometimes the seller and the buyer may agree on dividing the real estate tax in the deed of sale, but this does not have an effect on how the real estate tax is imposed. Specifically, the Finnish Tax Administration does not divide the real estate tax between the seller and buyer as based on the deed of sale.

Please note that the changes in the real estate information that occurred during the tax year do not yet affect the real estate tax of the same year.

Example: Matti owns a real estate unit at the start of the tax year 2020 (1 January 2020). Matti sells the real estate unit in February 2020. The sale does not affect Matti’s real estate tax in 2020. He does not need to submit a real estate tax return due to the change of ownership in 2020, because the change will only affect the real estate tax respective to 2021.

What kind of right of ownership or possession do you have to the real estate unit?

State here what kind of right of ownership or possession you have to the real estate unit. Also state if the right of ownership, or possession or leasehold right, has ended. Also fill in this section when your share of the real estate unit has changed. 

• Right of ownership and possession
  • Usually, the owner of the real estate unit has the right of ownership and possession to the real estate unit. Choose this option if you have both rights.
  • A party other than the owner of the real estate unit can only have a right of possession affecting real estate taxation if the right of possession has been determined by a will or deed of gift. In addition, the surviving spouse can reserve the right of possession to a real estate unit that was the joint home of the spouses.
  • If the right of possession to the real estate unit has been reserved in connection with the sale, it does not affect the real estate taxation; instead, the buyer is liable to pay real estate tax.
• Only the right of ownership (someone else has right of possession)
  • Select this option if you only have the right of ownership to the real estate unit, not the right of possession. This is the case when, for instance, you have received the real estate unit as a gift or through a will, but the right of possession to the real estate unit has been reserved for the donor or another party in the will or deed of gift. The surviving spouse may also have reserved the right of possession to the real estate unit that was the joint home of the spouses.

• Right of possession only
  • Select this option if you have the right of possession but not the right of ownership. This is the case, for instance, when the right of possession to the real estate unit has been reserved in a will or deed of gift, or when the surviving spouse uses the right of possession to a real estate unit that was the joint home of the spouses.

• Leasehold right (no right of ownership to land)
  • Select this option if you have purchased or otherwise gained the ownership or possession a building on land owned by another party (such as a rented plot), and the real estate unit is not included in your real estate tax decision. Report the information on the building in section 5 (Building). If the real estate unit includes several buildings, fill in a separate form for each of them, or submit a report via MyTax. Section 4 (Land) does not need to be filled in, because the owner of the land is liable to pay tax on the land.
• I no longer have the right of ownership or possession to the real estate unit
  • Select this option if the real estate unit is still included in the tax decision, even though you have sold the real estate unit before 1 January of the tax year, for instance. Also select this option if you no longer had the right of ownership or possession to the real estate unit at the start of the tax year for other reasons.
• I no longer have a leasehold right (leasehold right and building have been transferred)
  • Select this option if you have transferred the buildings still shown in the tax decision that are located on a rented plot or otherwise on land owned by another party. If you have transferred the leasehold right and the building, you do not need to report the transfer of buildings separately in section 5 (Building) of the form.

Your share of the real estate unit on 1 January (for example, 1/2)

Report your share of ownership of the real estate unit here if your share has changed. Also report the share owned by your spouse and the other owners of the real estate unit in section 6 (Further information).

This subsection is the same for all options:

Total area according to external dimensions

Total area of the building or part of it in square metres. Report the total area with the accuracy of a square metre.

The total area of a building is calculated as based on external dimensions. It includes the areas of all floors, basements and thermally insulated attic rooms. However, balconies, canopies or areas with a clearance of less than 160 cm are not included in the total area. Attics and porches are only included in the total area if they are thermally insulated. The area of a row house or a semi-detached house refers to the area of the entire building.

Also fill in the other details for the correct building type:

Detached house (single-family house, semi-detached house, row house)

Bearing structure

State whether the bearing structure of the building is made of wood, stone or metal. The bearing structure affects the discount percentage, due to the age of the building together with the building type.

Heating

Select the option Central heating if the building has a heating system with water circulation. It is irrelevant whether the source of heat is oil, wood, coal, district heat, geothermal heat, electric heating with thermal storage, or an air-circulation heating system.

Select the option Other if the building is heated with a radiator connected directly to the electricity grid or other similar heater.

Leisure property

A leisure property refers to a building that has been built mostly for spending leisure time, such as a summer cottage. The building must be an ordinary leisure property. If the size, use, level of construction or level of equipment are essentially different from an ordinary leisure property, the building is considered a detached house in real estate taxation. A building is a detached house if, for instance, its size is at least 80 m2, its equipment level is the same as that of a detached house, and it is suitable for year-round use. Report the information on such a building in the Detached house section of the real estate tax return. Also fill in the section Detached house if a single-family house is in leisure time use.

Total area according to external dimensions

Read the instructions on how to calculate the total area in the beginning of section 5.7 of the instructions for filling in the form. Include all floors, basements and thermally insulated attic rooms in the calculations.

The porch must be large enough to spend time in. Not all sides of the porch have a wall. The porch area is not included in the total area of the building.

Also state if the building has the following equipment or properties:

• Electricity
  The building has electricity if it is connected to the electricity grid or if an electric current of 230 V is conducted to the building. The production method of the electricity does not matter.
• Water pipe
  A fixed water pipe system installed in the building where the water comes from a regional water supply system or well (a dug or drilled well) either using pressure or a pump is considered a water pipe.
• Sewer
  A fixed sewer system installed in the building that ends in the regional sewer network, a settling well, cesspool or small sewage treatment plant is considered a sewer. A hole in the ground used to treat so-called grey water is not a sewer.
• WC
  The WC must be flushable with water and connected to a sewer. A chemical toilet or an electric dry closet is not a WC.
• The building is habitable in winter
  The building is habitable in winter if it has heating and sufficient insulation or wall thickness to ensure that the temperature of the building remains at +15 degrees Celsius at minimum with heating. A heat-storing fireplace, stove or electric heater can be used for heating. Being habitable in winter is not the same as suitable for permanent habitation. This means that the building does not need to be suitable for permanent habitation.
• The building has a sauna bath
  The sauna bath must be located inside the bearing structures of the building. If the sauna bath constitutes a separate building, check the option No. In that case, fill in the information on the sauna separately in the section Utility building, and select Sauna bath from the options in that section.
