Should I roll my 401(k) into an IRA before leaving the US?
Short answer: Rolling a 401(k) to an IRA before moving back to Europe offers more investment flexibility and potentially lower fees, but you may lose federal creditor protection and certain tax treaty benefits. Some treaties (like the US-France treaty) provide clearer protection for 'employer-sponsored' plans than for individual IRAs.

Why it works this way
The primary reason to roll over is control. Most 401(k) plans have a limited menu of funds. By moving the money to an IRA at a firm like Interactive Brokers or Schwab, you can invest in a wider range of assets. This is especially important once you move, as your investment choices may be further restricted by EU regulations.
Treaty language is the critical variable. Many US-Europe treaties refer specifically to 'pensions' or 'retirement plans' without clearly defining if an IRA qualifies. While practice usually treats them similarly, a 401(k) is indisputably an employer plan, providing a stronger legal shield against foreign taxation of the account's internal growth.
Creditor protection is also a factor. Under US federal law (ERISA), 401(k) assets are generally protected from all creditors. IRAs have more limited protection that varies by state. If you plan to remain in Europe permanently, this US-centric protection might be less relevant, but it remains a structural difference between the two.
The expensive mistake: Rolling over after you have already become a European resident
If you initiate a rollover while resident in Europe, the move from 401(k) to IRA could be viewed by your home country as a 'distribution' and a 'contribution,' potentially triggering immediate tax. It is almost always safer to complete the rollover while you are still a US tax resident.
What to do
- Check the specific treaty article for 'Pensions' — Verify if your destination country (e.g., France, Germany, UK) treats IRAs and 401(k)s identically for tax-deferral purposes.
- Complete the rollover while still in the US — Use a 'direct rollover' to avoid any withholding and ensure the transaction is recorded while you have a US address and residency.
- Choose a custodian that supports non-residents — If you roll to an IRA, ensure the new custodian is comfortable with you moving to Europe shortly after the account is opened.
