Tax Treaty Relief in Sweden

Sweden's double-taxation treaty network is one of the most extensive in the European Union, spanning roughly 90 bilateral agreements that cover almost every major economy. The network is administered by Skatteverket, the Swedish Tax Agency, under the framework of domestic legislation at Lag om avrakning av utlandsk skatt (SFS 1986:468). Whether you are a Swedish resident earning foreign income or a non-resident shareholder of a Swedish company, the rules governing which country taxes what, and how much relief you can reclaim, follow a relatively clear hierarchy. Consulting a qualified tax professional is essential whenever the facts span more than one jurisdiction.

How does Sweden eliminate double taxation for its residents?

For Swedish tax residents, the standard mechanism is the avrakning -- a direct credit of foreign tax paid against the Swedish income tax liability on the same income. Skatteverket's guidance confirms that credit is granted at the lower of (a) the foreign tax actually paid, or (b) the Swedish tax that would have applied to that same foreign income [1]. To illustrate: if foreign tax withheld on a dividend totals SEK 10,000 and the Swedish tax on that same dividend income equals SEK 8,000, the maximum avrakning credit is SEK 8,000 -- the excess foreign tax does not reduce Swedish tax on other income. Unused credit that cannot be absorbed in the current year carries forward for up to five years, provided the foreign-source income is reported on each year's Swedish tax return [1].

The credit cap also interacts with treaty rates: if a treaty limits source-country withholding to 15% but the paying country deducts 27%, only the treaty-permitted 15% qualifies for avrakning; the excess 12% must be reclaimed from the source country directly.

What is the exemption method and when does it apply?

Not all treaties use the credit method. Some bilateral agreements with Sweden -- particularly older treaties -- provide for the undantagandemetoden (exemption method), under which Sweden simply excludes the foreign-source income from Swedish tax altogether rather than taxing it and granting a credit [2]. Practical examples include certain categories of employment income and some pension flows covered by the Nordic Tax Convention (the multilateral treaty covering Sweden, Denmark, Finland, Norway, Iceland, and the Faroe Islands, signed 1996, amended most recently in 2018). When the exemption method applies, there is no avrakning calculation because Swedish tax is never levied on the income in the first place. A licensed skatteradgivare can confirm which method your specific treaty uses for each income category, since the same treaty may use credit for dividends but exemption for certain employment income.

Sweden also provides two domestic exemptions for qualifying individuals: the six-month rule and the one-year rule. Under these, Swedish-resident employees working abroad may have their foreign employment income entirely exempt from Swedish tax -- which likewise removes the need for any avrakning credit [1].

What is kupongskatt and how do treaties reduce it?

Kupongskatt is Sweden's source-country withholding tax on dividends paid by Swedish limited companies (aktiebolag) to shareholders with limited Swedish tax liability -- that is, non-residents. The standard domestic rate under Kupongskattelagen (SFS 1970:624) is 30% [3]. Sweden does not levy withholding tax on interest paid to non-residents (abolished since 1 January 1984) or on royalties (never imposed domestically).

Bilateral treaties reduce the 30% kupongskatt rate, typically to 5-15% for portfolio dividends. The table below shows a selection of treaty rates in force as of June 2026 [4]:

Non-residents may apply for a refund of kupongskatt withheld above the treaty rate using Form SKV 3740 (or SKV 3742 for Swiss-resident claimants). The refund application window is five years from the date the dividend was received. Skatteverket currently experiences extended processing times for refund claims; allow at least four months after the dividend date before submitting, as paying companies require that period to file their own withholding reports [3].

Alternatively, at-source relief at the lower treaty rate is available when the non-resident shareholder provides a valid residency certificate (hemvistintyg) confirming treaty entitlement to the withholding agent before the dividend is paid.

How does the residence tie-breaker work?

When an individual is tax-resident under the domestic law of both Sweden and another treaty country simultaneously, the treaty's tie-breaker clause -- drawn from OECD Model Convention Article 4 -- resolves the conflict by applying the following tests in strict sequence [2]:

1. Permanent home -- resident where a permanent home is available; if available in both, proceed to step 2.
2. Centre of vital interests -- personal and economic ties (family, employment, financial accounts, social memberships) determine the country of closer connection.
3. Habitual abode -- the country where the individual spends more time.
4. Nationality -- citizenship of one country breaks a remaining tie.
5. Competent authority agreement -- the two tax authorities resolve the remaining case bilaterally.

Sweden's domestic rules additionally create unlimited tax liability for anyone who is domiciled in Sweden, stays in Sweden for six months or more in a year, or retains a significant connection (vasentlig anknytning) after emigrating. The vasentlig anknytning ten-year rule reverses the burden of proof five years after departure: for the first five years after leaving Sweden the emigrant must prove to Skatteverket that ties no longer exist; after five years Skatteverket carries that burden.

What happened when Sweden terminated the Portugal and Greece treaties?

The Swedish Riksdag voted on 2 June 2021 to terminate both the Sweden-Portugal and the Sweden-Greece double-taxation treaties, effective 1 January 2022 [5]. The reason was explicit: both Portugal and Greece had introduced domestic rules (Portugal's Non-Habitual Resident regime, Greece's flat-tax regime for foreign pensioners) that allowed individuals relocating from Sweden to pay very low or zero tax on pensions and capital gains sourced in Sweden -- producing an outcome where neither country taxed the income meaningfully.

After termination, former Swedish residents now living in Portugal or Greece no longer benefit from any bilateral protection. Swedish occupational pensions and public pensions with a Swedish source are now subject to the 25% SINK tax (Sarskild inkomstskatt for utomlands bosatta, special income tax for non-residents). Sweden's domestic ten-year rule on capital gains from shares in Swedish companies also applies without any treaty cap. Individuals in those countries must look entirely to Portugal's or Greece's domestic relief mechanisms to avoid double taxation -- there is no Swedish treaty obligation to eliminate it on the Swedish side.

Similarly, Sweden suspended its treaty with Russia in its entirety from 10 February 2025 following Russia's unilateral suspension of provisions of the agreement, restoring the full 30% kupongskatt rate for Russian-resident dividend recipients [3].

How do you claim avrakning on the Swedish tax return?

Swedish residents with foreign-source income declare the income and claim the credit on Form Inkomstdeklaration 1 (income tax return) filed annually, typically by 2 May for the preceding income year. Claimants check the settlement box under "Ovriga upplysningar" (other information) and, for complex cases or carry-forward claims, complete the separate Form SKV 2703 (avrakning av utlandsk skatt) [1]. The form requires:

• Type of income (employment, dividend, interest, capital gain, rental, pension)
• Amount of foreign income in SEK (using the applicable Riksbank exchange rate)
• Country of origin
• Amount of foreign tax paid in SEK
• Exchange rate used
• Related business expenses deductible against that income

For investment income -- dividends, interest, and income from investment savings accounts (investeringssparkonto) -- where the withholding is already shown on the annual earnings statement (kontrolluppgift), Skatteverket calculates the avrakning automatically and reflects it in the preliminary tax assessment. No separate SKV 2703 is needed for those routine cases. Foreign property tax qualifies for credit only if the property generated rental income or a capital gain that is also taxable in Sweden [1].

An alternative to the avrakning credit exists: foreign tax may instead be claimed as a deduction from income under employment or capital income categories. Skatteverket notes this is generally less beneficial than a credit, but can be advantageous when capital-income deficits would otherwise prevent the credit from being absorbed [1].

For disputes where bilateral treaty relief is denied or inconsistently applied, Swedish residents may request a Mutual Agreement Procedure (MAP) via Skatteverket's competent authority office at [email protected]. MAP applications must be submitted within three years of the first notification of the disputed assessment (five years under the Nordic Tax Convention). For intra-EU transfer-pricing and permanent-establishment disputes, mandatory binding arbitration under the EU Dispute Resolution Directive (2017/1852) is also available.
