ISK (investeringssparkonto)
An ISK (investeringssparkonto) is the most popular Swedish account for funds and shares. Instead of taxing your gains, it charges a small standardised tax each year on the whole balance. That makes it simple: no reporting of individual trades, and no capital gains tax when you sell.
How it is taxed
The yearly charge is schablonbeskattning, built on the statslåneränta, about 1.07% of the balance a year. From 2026 the first 300 000 kr of your average value is exempt as a tax-free amount (fribelopp), so small and mid-sized holdings pay very little.
When it fits
An ISK suits money you expect to grow and hold for the long term. For money you might sell at a loss, or need very soon, a regular account with kapitalvinstskatt (tax only on realised profit) can be better, because in an ISK you cannot deduct losses.
Where it shows up
- Compound savings
- ISK vs pension
- Withdrawal strategy
You can’t deduct losses in an ISK, and foreign dividends are taxed at source without full relief. For heavy foreign-dividend portfolios or naming a beneficiary, a kapitalförsäkring may suit better.
