How do I handle my US 401k and IRA when moving back to Germany after 20 years in the US?

Q: How do I handle my US 401k and IRA when moving back to Germany after 20 years in the US?

Understand your options for managing a US 401k and IRA when returning to Germany, including tax implications, withdrawal rules, and investment strategy adjustments.

Returning to Germany after a long period in the US creates complex tax and investment challenges for your retirement accounts.
While you can usually keep your 401k and IRA, the way you access, invest, and report them changes significantly.

Quick Answer

You can keep both accounts when living in Germany, but may not be able to make new contributions.
Withdrawals are taxed in the US first, and potentially in Germany : the US-Germany tax treaty determines how double taxation is handled.
You must decide whether to leave accounts in the US, roll over into another plan, or start withdrawals.

1. Keeping your 401k and IRA after relocation

401k:

Most providers allow you to keep your plan if you have left your employer.
Some may require a US mailing address (solution: US friend/family address or use a mail forwarding service).

IRA:

You can keep Traditional or Roth IRAs, but US brokers may restrict new investments for non-US residents.
No new tax-deductible contributions while living in Germany.

2. Tax implications under the US-Germany treaty

401k/Traditional IRA withdrawals → taxed in the US at source (typically 15% for treaty residents), then declared in Germany.
Roth IRA → withdrawals may be tax-free in the US but taxable in Germany if growth was not previously taxed here.
Germany may give a credit for US taxes paid, avoiding double taxation.

3. Investment access issues

Some US brokers (e.g., Vanguard, Fidelity) limit buying new US mutual funds or ETFs if you have a foreign address.
Existing holdings can usually be kept but may not be traded actively.
Switching to individual stocks or US ETFs before moving can give more flexibility.

4. Common strategies

Leave accounts in the US
- Keep tax-deferred status.
- Accept limited trading flexibility.
- Coordinate withdrawals for lowest tax rate.
Roll over 401k → IRA
- May reduce fees, expand investment options.
- Check if your provider accepts foreign residents.
Gradual withdrawals before moving
- If current tax bracket is low, may save money long-term.
- Beware early withdrawal penalties if under 59½.

5. Practical example

You have:

401k: $500,000
Traditional IRA: $200,000
You move to Germany in 2025, age 55.
US withholds 15% on a $20,000 withdrawal.
In Germany, you declare the $20,000, pay local tax, but claim a credit for the US withholding.
Depending on your German tax bracket, you may owe an extra €1,000–€2,000.

6. Tips for smooth transition

Update your US address before leaving.
Consider converting some Traditional IRA to Roth IRA while still in the US if in a low tax bracket.
Keep USD bank accounts for transfers.
Track currency conversion for tax reporting.
