How is my Swedish tjänstepension or premiepension treated under the US treaty?
Short answer: Sweden's occupational tjänstepension and the state-run premiepension are pensions for treaty purposes, so the US–Sweden tax treaty's pension article generally governs which country taxes a distribution. The treaty does not, however, resolve whether the funds a US citizen chooses inside the premiepension's fund menu or a tjänstepension plan are themselves PFICs — that is a separate question entirely.

Why it works this way
The treaty's pension article is built to stop a workplace or state pension from being taxed as if it were a current investment account; it generally defers taxation to the point of distribution and allocates taxing rights between the US and Sweden.
What the treaty does not do is change how the IRS classifies the underlying fund holdings. The premiepension fund marketplace and many tjänstepension providers default savers into Swedish and European funds, which are PFICs regardless of the pension wrapper around them.
Because contributions to tjänstepension are usually made by the employer directly rather than from already-taxed salary, the US tax treatment of the accrual itself is also worth confirming with a preparer familiar with Swedish pensions, rather than assumed to mirror a 401(k).
The expensive mistake: Treating the pension wrapper as the whole answer
A pension being treaty-protected on withdrawal says nothing about whether the funds inside it are PFICs today. Both questions need separate answers.
What to do
- Confirm which pillar each pension belongs to — Tjänstepension, premiepension and inkomstpension have different mechanics.
- Check the fund selections inside — Choose the most conservative non-fund options where PFIC exposure cannot be avoided.
- Get the treaty position on contributions and growth confirmed in writing — Don't assume 401(k)-style treatment applies automatically.
