Are you ready for major changes to your tax return in Sweden? The ränteavdraget 2026 – Sweden's interest deduction – faces proposed reforms that could significantly impact both private individuals and landlords' finances. According to Skatteverket, Sweden's Tax Agency, the deduction for interest expenses on mortgages and other loans will be reduced starting in 2026, meaning smaller tax refunds for many people living in Sweden. For you as a private person with a mortgage, it's about adjusting your finances, while landlords risk higher tax costs on their property investments. It's high time to understand how these changes hit your tax return and what alternatives exist. As a landlord, Bofrid can help by quickly and easily matching you with reliable tenants across Sweden, so you can optimize your rental income. In this guide, we break down everything you need to know to prepare for 2026.
What is the ränteavdraget?
The ränteavdraget is a key tax relief in Sweden, regulated by the Income Tax Act (IL, or Inkomstskattelagen). It allows you to deduct paid interest on loans from your capital income, reducing your tax by 30 percent on the first 100,000 kronor in deficit and 21 percent on amounts above that. This works by treating interest as negative capital income that offsets positive capital income, such as capital gains or other interest income.
In your tax return, or deklaration, the deduction automatically affects your final tax after offsetting. For example, if you've paid 50,000 kronor in interest on a mortgage (bolån) and have 20,000 kronor in capital gains, the deficit is offset, and you get a deduction on the remaining 30,000 kronor. The same principle applies to personal loans – interest on a 100,000-kronor loan at 5 percent yields 5,000 kronor in deductible interest, equivalent to up to 1,500 kronor in tax relief.
With the proposed changes to ränteavdraget 2026, it's especially important for expats and residents in Sweden to know the current rules to plan your finances.
Which types of interest are covered?
Several types of interest are deductible under current Swedish rules:
- Mortgages (bolån): Interest on loans for buying a home or refinancing a property in Sweden.
- Consumer loans: Interest on personal loans, car loans, or credit card purchases (excluding interest-free periods).
- Capital share loans: Interest on loans taken to invest in unlisted shares or securities.
Other examples include student debts and interest on unsecured loans (blancolån), as long as they are properly documented by the lender.
How is it declared today?
Declaring is straightforward via Skatteverket's e-service Inkomstdeklaration 1 (Income Tax Return 1), the standard tax return form used by most individuals in Sweden. Banks and lenders often pre-fill the interest amounts in the capital section (the boxes for loan interest).
Always check the details and supplement if needed with Bilaga K4 for capital. There, you specify interest per loan agreement, including the lender's name and amount. Skatteverket then calculates the deduction automatically – approve and submit by May 2 at the latest.
What changes are proposed for ränteavdraget 2026?
The Swedish government has proposed major changes to ränteavdraget 2026 in the 2024 budget proposition (budgetpropositionen 2024). The current percentage-based deduction, offering 30 percent on interest over 100,000 kronor, will be replaced by a standard deduction (schablonavdrag) of 15,000 kronor per person (30,000 kronor for cohabiting couples). Skatteverket's guidance confirms this takes effect on January 1, 2026.
The reform aims to simplify tax returns, reduce administration, and free up funds for other tax cuts, like reduced marginal tax rates. For many households in Sweden, this means a reduction in deduction rights, especially for those with high interest expenses.
New standard rule instead of full deduction?
The shift from percentage-based deduction to a fixed standard deduction is the biggest change. Today, exact interest amounts are calculated and deducted proportionally. From 2026, it's a fixed amount regardless of actual interest paid.
This benefits low-interest households but hits hard those with large loans. Skatteverket recommends planning ahead using their tax calculation tools.
Impact on different loan types
The changes affect various loans differently:
- Mortgages: Most are negatively impacted, as average interest often exceeds the standard amount. A 3-million-kronor mortgage at 4 percent yields over 30,000 kronor in deduction today – now max 15,000 kronor.
- Unsecured loans (blancolån): Often smaller amounts, so the standard may suffice. But high-interest loans quickly exceed it.
- Business loans: Private individuals are affected similarly, but companies have separate rules. Check with Skatteverket for hybrids.
Plan your finances now to minimize the effects of ränteavdraget 2026 in Sweden.
How do the changes affect your tax return in 2026?
With the proposed changes to ränteavdraget 2026, your tax return in Sweden will require more detailed reporting. Skatteverket is introducing new fields in Inkomstdeklaration 1 to handle the reduced deduction rights, likely from 30% to 21% on mortgage interest above a certain threshold. Follow this step-by-step guide to adapt your 2026 tax return and avoid unnecessary additional taxes (eftertaxeringar).
Example: If you've paid 50,000 kr in mortgage interest, you previously deducted 15,000 kr (30%). From 2026, it might be 10,500 kr (21%), but with requirements for specified documentation per loan.
Step 1: Gather documentation
Start by retrieving control statements from your bank or lender by March 2026. These are crucial for the new requirements.
- Interest specification: Detailed breakdown per loan, including interest, amortization, and loan amount.
- Control statement (KU10): Automatic reporting from lenders to Skatteverket – verify against your copy.
- Receipts if applicable: For personal loans without automatic reporting, like car or consumer loans.
Missing documentation? Contact the lender immediately to avoid rejection of the deduction.
Step 2: Fill in the tax return
Log in to Skatteverket's e-service for Inkomstdeklaration 1 in April 2026. Navigate to the Interest expenses and interest income section under the "Other information" tab.
- New field: Interest deduction per loan type – Enter amounts for mortgages, personal loans, and others separately.
- New field: Limitation amount – Enter the threshold for reduced percentage (e.g., 100,000 kr).
- Calculate the deduction: Use Skatteverket's calculator – input total interest and get a deduction proposal.

Overall, digital tools simplify the process, but double-check calculations for ränteavdraget 2026.
How are landlords specifically affected?
Landlords with mortgages on rental properties in Sweden are uniquely impacted by the proposed changes to ränteavdraget 2026. These reforms could reduce deduction rights for interest expenses, directly affecting your tax return through capital income. For rental properties, interest costs are often treated as part of capital income, but there are key differences depending on property type.
By optimizing your rental management, you can mitigate the effects. Bofrid helps landlords quickly find stable tenants across Sweden, providing reliable rental income and better financial balance.
Deductions for rental properties
Deductions differ significantly between private housing and business property. For private housing (e.g., small rental buildings with few apartments), interest is deducted at 30 percent after a standard income of 21 percent is calculated. This means ränteavdraget 2026 could reduce your net deduction and increase tax on capital income.
For business property (larger properties primarily for renting), interest costs are fully deductible as operating expenses in the business. Changes to ränteavdraget 2026 mainly affect privately owned rental properties, where careful calculation in the tax return is needed to maximize deductions.
Strategies to minimize tax effects
Here are practical tips for handling the changes:
- Refinance loans: Review your mortgages now to lock in lower rates before ränteavdraget 2026 takes effect. This reduces interest costs and tax impact.
- Optimize property structure: Consider reclassifying to business property if it fits your operations for better deduction rights.
- Stabilize rental income: Use Bofrid to efficiently match with reliable tenants. Stable rent compensates for higher taxes and simplifies your tax return – quickly and easily across Sweden.
What other deductions can you utilize instead?
With the proposed changes to ränteavdraget 2026, it's wise to explore other deductions to maximize your finances as a landlord in Sweden. The ROT deduction (for renovations), support for energy efficiency, and deductions for property maintenance are excellent alternatives. These can offset reduced interest deductions and improve your property's value, making it easier to rent via platforms like Bofrid.
By strategically planning investments, landlords can optimize total deductions. Contact Skatteverket for personal advice and Bolagsverket (Sweden's Companies Registration Office) if you run rentals through a company.
ROT and RUT deductions
The ROT deduction covers renovations, conversions, and extensions up to 30 percent on labor costs. Combine this with interest changes by financing ROT work with loans – even if ränteavdraget 2026 decreases, ROT provides direct tax savings.
The RUT deduction suits cleaning and maintenance services for your property. As a landlord, you can deduct costs for shared spaces, for example. Tip: Use ROT for energy efficiency like insulation or new windows, lowering operating costs and boosting appeal to tenants.
- Document all receipts carefully.
- Apply via your tax return for easy handling.
Deductions for property maintenance
Deductions for property maintenance include repairs like painting, roof replacement, and plumbing work. This is especially valuable for landlords – for instance, deduct costs to keep apartments in top condition for renting.
Practical examples:
- Floor replacement in rental apartments: Fully deductible as maintenance.
- Facade painting: Deduction up to 100 percent if classified as direct deduction.
Maximize by scheduling work annually and combining with ROT. For company-run rentals, follow Bolagsverket's guidelines for correct accounting. This keeps your finances strong despite changes to ränteavdraget 2026.
