Is there a tax treaty between the US and Sweden?
Short answer: Yes. The United States and Sweden have an income tax treaty, signed in 1994 and amended by a 2005 protocol, and a separate Social Security totalization agreement in force since 1987. The tax treaty allocates taxing rights on income including pensions; the totalization agreement prevents paying into both countries' social security systems on the same work and helps combine credits toward benefits.

Why it works this way
Like other modern US treaties, this one contains a saving clause letting the US continue to tax its citizens as if the treaty did not exist in most respects, so the treaty mainly helps through specific articles — pensions, the foreign tax credit, and residency tie-breakers — rather than a blanket exemption.
The totalization agreement is the piece people miss: an American employee sent to Sweden by a US employer can often stay on US Social Security instead of Swedish social charges for a set period, using a certificate of coverage, while someone locally employed in Sweden builds Swedish credits instead.
A 2005 protocol updated several of the Convention's provisions and added a rule allowing the US to continue taxing certain former citizens and long-term residents for ten years after they lose that status — relevant to anyone considering renouncing citizenship while resident in Sweden.
The expensive mistake: Assuming the treaty eliminates double taxation automatically
The treaty and its credit mechanisms have to be claimed correctly on the US return every year. An unclaimed or mis-claimed credit is the most common way Americans in Sweden end up paying more than they should.
What to do
- Identify your residency position under the tie-breaker rules — Important if you split time between the US and Sweden.
- Check your Social Security coverage — Confirm whether you need a certificate of coverage or are already paying into the Swedish system.
- Make sure your preparer actually claims the treaty articles that apply — Pension, dividend and credit provisions do not apply themselves.
