Sweden Mortgage Interest Tax Deduction Calculator — Ränteavdrag

Sweden's ränteavdrag (interest deduction) allows homeowners to deduct mortgage interest from their taxable income. The rate is 30% on the first SEK 100,000 of annual interest, and 21% on the excess — regardless of your actual income tax rate.

On a SEK 3,000,000 mortgage at 4%, annual interest is SEK 120,000. Tax saving: (100,000 × 30%) + (20,000 × 21%) = 30,000 + 4,200 = SEK 34,200/year (SEK 2,850/month).

Effective after-tax rate on the full loan: approximately 2.86%.

• Applies to all loans — not just mortgages. Personal loans, student loans, and car loans also qualify
• The SEK 100,000 threshold is per taxpayer — couples can each claim 30% on up to SEK 100,000
• No loan amount cap — any size mortgage qualifies
• Applies to primary residence, summer houses, and investment properties
• The 30%/21% rates are fixed — your actual marginal rate doesn't affect the deduction

The deduction is automatically included in your pre-filled inkomstdeklaration from Skatteverket. Your bank reports paid interest directly to Skatteverket. Verify the amounts via Skatteverket's app or at skatteverket.se — deadline is May 2 for individuals.

To reduce tax withheld during the year, apply for jämkning (tax adjustment) — Skatteverket reduces your preliminary tax to account for the deduction.

Why was the threshold changed to SEK 100,000?
The cap was introduced in 2016 to reduce incentives for high borrowing. Before 2016, the 30% rate applied to all interest without limit. The 21% rate on excess interest was designed as a softer phase-out.
