Reform of investment fund and ISK taxation
Sweden has reformed taxation of certain investment funds to align with EU state aid and free movement requirements, with adjustments to how ISK (investment savings account) returns are calculated.
What changed and what to do
What changed
Sweden amended its rules on the taxation of investment funds and ISK accounts following pressure from EU free movement of capital principles. The ISK annual flat tax is calculated as a percentage of the account value using the government loan rate (statslåneränta) plus 1 percentage point, with a floor of 1.25%. For 2024, the statslåneränta was 2.62%, resulting in a total ISK rate of approximately 3.62% of account value. Certain fund structures previously benefiting from favourable treatment have been brought within standard rules.
Who it affects
- Individual investors holding Swedish ISK (investment savings accounts)
- Fund managers operating investment funds in Sweden
- Investors in foreign funds marketed in Sweden
What to do
Review your ISK holdings to understand the effective annual tax rate for 2024 and 2025 based on the updated statslåneränta. For high-return portfolios, ISK may still be advantageous over standard capital gains tax (30%); for lower-return or bond-heavy portfolios, compare total tax costs. Consult a financial adviser if you are considering restructuring fund holdings.
