Investment Account Comparison: ISK vs KF vs AF (2025)
Compare ISK, Kapitalförsäkring, and Aktie- & Fondkonto to choose the optimal account for your situation.
Choose the Right Investment Account for 2025
There are three main types of investment accounts in Sweden: ISK (Investment Savings Account), Kapitalförsäkring (Capital Insurance), and Aktie- & Fondkonto (Stock & Fund Account). Each account type has different tax rules that affect your net returns. With our comparison calculator, you can easily see which account type suits you best based on your circumstances and expected returns.
2025 Tax Rules
ISK and KF are taxed with flat-rate tax: 2.96% × 30% for 2025, with a 150,000 SEK tax-free allowance. AF is instead taxed with 30% capital gains tax on realized gains. For long-term investors, ISK/KF may be advantageous since the tax is independent of actual returns, while AF may be better if you rarely realize gains or have low returns.
