The Swedish 10-Year Rule (Tio-årsregeln): §3:19 Inkomstskattelagen
Sweden's tio-årsregeln is codified in §3:19 Inkomstskattelagen (IL — Income Tax Act). The rule: Sweden retains the right to tax capital gains on Swedish shares (and certain other Swedish-situated assets) for 10 years after the shareholder departs Sweden, even if the gain is realised abroad as a non-resident. Scope: applies to shares and securities issued by Swedish companies (listed on Nasdaq Stockholm, First North, or unlisted Swedish companies). Also applies to Swedish mutual fund units. Does not apply to: Swedish real estate (taxed under different rules); bonds and fixed income; foreign shares. How it works: if you sell Swedish shares in year 7 after departure, Sweden can claim CGT on those shares. The 10-year window runs from the date you ceases Swedish residency (as confirmed by Folkbokföring deregistration). Treaty limitation: many of Sweden's double tax treaties limit the 10-year rule — Sweden may only tax the gain if Sweden's right is preserved in the relevant DTA. Under the Sweden-USA treaty: the 10-year rule IS limited — generally, the USA has exclusive taxing rights on capital gains after 5 years of US residency. Check the specific DTA. Planning implication: if you plan to sell significant Swedish share holdings, consider the timing relative to the 10-year window and applicable DTA. Swedish nationals with large portfolios of Swedish equities (common among Ericsson, Volvo, and bank employees with employee share plans) should model the 10-year exposure before departure.
SINK: Special Income Tax for Non-Residents (Särskild inkomstskatt)
SINK (Lag om särskild inkomstskatt för utomlands bosatta) is Sweden's non-resident income tax. Rate: flat 22.5% on Swedish-source employment income, pension income, and certain other income (dropping to 20% from 2027). Compare to the normal Swedish progressive rate (32–52%+ for residents). Who chooses SINK: non-residents who work in Sweden or receive Swedish-source income can apply to pay SINK instead of the standard Swedish income tax. Pension under SINK: Swedish pension (Allmän pension, occupational pension) paid to non-residents is subject to SINK at 22.5% — simpler than filing a full Swedish non-resident return. SINK application: apply via Skatteverket using Form SKV 4350. SINK vs standard assessment: for some non-residents, it may be more beneficial to file a standard Swedish non-resident return (skattskyldig i Sverige) and claim deductions — compare the two options with a Swedish skatterådgivare. Swedish dividend tax: dividends from Swedish companies are subject to 30% källskatt (withholding) for non-residents — this is not SINK but a separate withholding. Under most DTAs, this is reduced (e.g., to 15% under Sweden-USA DTA). SINK also provides a simpler way to handle Swedish employment for persons working in Sweden while living abroad.
Folkbokföring Deregistration from Skatteverket
All Swedish residents are registered in Folkbokföringen (population register) maintained by Skatteverket. When leaving Sweden permanently: you must officially notify Skatteverket of your departure via Form SKV 7302 (Anmälan om utflyttning — Notification of Emigration). Submit this form at a Skatteverket service centre or by post. The deregistration date in Folkbokföringen becomes your official Swedish residency cessation date — critical for the 10-year rule calculation. After deregistration: your Swedish personnummer (personal number, e.g., 800101-xxxx) remains valid. You retain it for life — it does not expire on departure. Your personnummer is needed for Swedish banking, pension administration, and tax matters after departure. Skatteverket sends tax notices and assessments to your registered address — update your contact address to your overseas address via SKV 7302 or via skatteverket.se. Residency rules: Sweden uses the 'significant connection' concept — if you retain a home in Sweden, Swedish family, or Swedish business interests, Skatteverket may consider you still Swedish-resident for tax purposes despite Folkbokföring deregistration. The 'väsentlig anknytning' (significant connection) test is Skatteverket's main tool for challenging departure.
ISK (Investeringssparkonto) and KF: Account Treatment on Departure
The Investeringssparkonto (ISK) is Sweden's investment savings account — the Swedish equivalent of an ISA. ISK is a highly tax-favoured vehicle for Swedish residents: instead of CGT on gains, you pay an annual flat wealth tax (schablonskatt) based on account value (approximately 1.086% of account value for 2025 — varies annually). When you leave Sweden and become non-resident: ISK accounts must be closed. You cannot hold an ISK as a non-resident — the account will be liquidated, and the proceeds paid out. The schablonskatt ends from the quarter of departure. Tax implications of closure: no CGT on the ISK closure (ISK gains are not subject to CGT — only the schablonskatt). The cash proceeds are yours. ISK closure timeline: close before or immediately after Folkbokföring deregistration to avoid administrative complexity. Kapitalförsäkring (KF — capital insurance/investment bond): similar to an ISK in tax treatment (schablonskatt-based). KF accounts can sometimes be maintained as non-residents, depending on the insurance company's terms — check with your provider. If maintained as non-resident: the Swedish schablonskatt ends; the destination country may tax the investment income from the KF. Advise your KF provider of your non-resident status.
Swedish Pension Abroad: Allmän Pension and Occupational Pension
Sweden's pension system has three tiers: (1) Allmän pension (general/state pension): includes inkomstpension and premiepension. Both are based on lifetime earnings and contributions. The pension is portable — payable internationally via Pensionsmyndigheten (Swedish Pensions Agency). Contact Pensionsmyndigheten (pensionsmyndigheten.se) to arrange international payment. Swedish pension age: flexible from 64 to 70 (minimum withdrawal age raised to 64 from 2026 under pension reform; was 63 from 2023). (2) Tjänstepension (occupational pension): employer pension, managed by ITP (private sector) or other collective agreement schemes. Vested after service requirements. Payable internationally — contact your occupational pension provider (SPP, Alecta, AMF, etc.) for non-resident payment arrangements. (3) Privat pension: personal pension savings (IPS — Individuellt pensionssparande) — tax-deductible during accumulation; closed to new contributions since 2016 but existing balances remain. SINK applies to Swedish pension payments at 22.5% flat rate (falling to 20% from 2027). Under many DTAs: the residence country has primary taxing rights on pensions — Swedish SINK (22.5%) is then credited in the destination country. Contact Skatteverket's SINK office (Skatteverkets utlandsservice) for SINK application on pension income.
