I'm Swedish, working in the US — what taxes apply when I move back to Sweden?
Short answer: A Swedish citizen moving back from the US becomes subject to unlimited tax liability in Sweden on worldwide income. US brokerage holdings are taxed at 30% on capital gains and dividends, US funds face an annual standard-income charge, RSUs earned in the US are allocated between the countries, and 401(k) withdrawals are generally taxed in Sweden under the treaty.

Why it works this way
Sweden taxes capital income at a flat 30%. Most Swedes at home use an investeringssparkonto (ISK), which replaces tax on actual gains with a low annual tax on a standard return — with the first 300,000 SEK of assets tax-free from 2026. US accounts cannot be an ISK, so a portfolio left at a US broker is taxed the traditional way — and foreign funds carry an annual standard-income charge (schablonintäkt) on their value.
Swedish citizens who left also face the 'ten-year rule' (väsentlig anknytning): for ten years after moving, Sweden can still claim you as tax-liable if you keep essential ties. In practice this matters more for people who left Sweden recently than for long-time US residents, but it is worth knowing in both directions.
Equity compensation earned while working in the US but vesting after you return is allocated by workdays. Sweden taxes the Swedish portion as employment income at full marginal rates, and the US taxes the US-source portion, with foreign tax credits to resolve the overlap.
The expensive mistake: Bringing a US fund portfolio into the Swedish system unchanged
US mutual funds and ETFs held directly are taxed less efficiently than equivalent holdings in an ISK. Deciding what to sell under US rules, and what to rebuild inside an ISK after arrival, usually beats carrying everything across.
What to do
- Plan the realisation of gains — Compare selling while US resident with selling as a Swedish resident at 30%.
- Open an ISK on arrival — Use it for the new long-term portfolio once you are Swedish resident.
- Track vesting workdays — Keep a record of US and Swedish workdays for every grant that vests after the move.
