It is important to differentiate between normal smaller repairs and modernisation i.e. major improvements. Each of these two categories has a different tax-deductibility. Accordingly, if you renovate your rental property and part of the work consists of small repair jobs, often done every year, while another part consists of an improvement project, you need to divide the paid total cost by reference to the types of renovations made.
Note: no deductions are available for the property owner’s work hours, even though you work on the repairs yourself. However, when you work at the property, you can claim the expenses you paid for the materials, and the travel expenses for your trips there (for tax year 2025, the base for travel expense deductions is 27 cents per kilometre).
If you own an apartment that you only use for renting out, and you renovate the apartment before offering it to tenants, please see further instructions in the detailed guidance under "Repair costs" -- Korjausmenot (in Finnish and Swedish).

Deductions for annual repair expenses
When annual repair work is done on a building, house or apartment, it is for keeping it in its good operating condition.
Repairs usually done almost every year include
- Painting and decorating
- Replacement of a stove, refrigerator or other appliances
- Replacement of fixtures such as kitchen cabinets and bathroom fittings
- Replacement of a door or window
Annual repairs can be claimed against the rental income of the year during which the repair expenses were paid.
Deductions for improvements
Extensions, alterations, betterments, modernisations, etc. are considered improvements.
The following are examples of improvements and modernisations:
- Converting an unheated storage space into a sauna
- Glazing balconies
- Improving foundations and load-bearing structures
- Improving heating and ventilation
- Installing and improving plumbing and drains
- Installing and improving electrical systems
You have two alternative options to claim deductions: depreciation year to year or deferred deduction at the time when you sell the property.
If you choose to deduct major repair expenses through depreciation, you must add them to the building’s acquisition cost, filling in the Itemisation of depreciation section, under Additions. Depending on building type, the maximum depreciation to be claimed is either 4% or 7% of acquisition cost.
Example. Katri owns a house where she had a tenant for the entire year 2025. After depreciation claimed for the previous year, the remaining value at the start of 2025 stood at €100,000. In 2024, Katri undertook major repairs on the house’s plumbing. Total expenses were €10,000.
When completing the depreciation calculations, Katri can enter €100,000 in Undepreciated acquisition cost at the start of the tax year, and correspondingly, €10,000 in Additions during the tax year.
For tax year 2025, Katri is entitled to claim 4 percent of depreciation, i.e. 4% × €110,000 resulting in €4,400. She claims this amount against the rental income received in 2025.
Accordingly, the remaining value at the start of the next year will be €106,600 (€110,000 minus €4,400). Katri also enters this value in the itemisation of her 2025 depreciation, in Undepreciated acquisition cost at the end of the tax year.
If you choose to deduct major repairs only at the time when you sell your property to an outside buyer, you are entitled to subtract the repair expenses from the selling price when you calculate your taxable capital gains. This way, the money spent on major repairs makes capital-gains taxes lower. If after the repairs, you have already claimed some depreciation, you can only subtract the undepreciated part of the acquisition cost, and the undepreciated part of the expenses caused by the major repair job.
Example. Tero has owned a garage building but he is selling it to a buyer for €80,000. The year before last, Tero undertook a major repair project – installation of an air conditioning system. He paid €6,000 in repair expenses. Because Tero claimed no annual depreciation based on the €6,000 spent, he is entitled to full subtraction when calculating the capital gains when the building is sold.
Taxable capital gains are calculated as follows:
Selling price €80,000
Acquisition cost - €65,000
Major repairs - €6,000
Resulting gains €9,000 for which Tero needs to pay 30% capital-gains tax, i.e. €2,700.
