Watch-outs for Sweden expats

⚠

Skatteverket deregistration: File emigration notice with Skatteverket. Sweden may apply a 3-year rule — continuing to assert residency and tax rights for 3 years if you have 'significant ties' to Sweden (property, family, business).

⚠

Swedish 3-year rule (3-årsregeln): Even after emigrating, Sweden may tax your Swedish-source income for 3 years unless you can prove you have no significant ties to Sweden. This is a major planning consideration.

⚠

ISK accounts in Portugal: The Swedish ISK (investment savings account) scablonintäkt system means you pay tax on a notional return, not actual gains. Portugal doesn't recognize this — you report actual realized income and gains. This may be beneficial (no tax until sale) or harmful (large gains taxed at 28%).
