A 401(k) or Individual Retirement Account (IRA), is a popular strategy among U.S investors to secure a golden visa investing in a Portuguese private equity or venture capital fund (500,000 euro).
Rollover
The first step is can convert your retirement fund to Self-Directed 401k (SDIRA) or Solo 401k which allows you to direct your retirement funds into a foreign country fund. A US company is used to own the self-directed IRA. LLCs must remain ‘in business’ to receive any interest and/or buy back.
Important
- A self-directed 401(k) provides several investment opportunities, including private loans and limited liability companies (eg. Delaware). However you need to be careful with the prohibited transactions set by IRS such as investing in life insurance, metals etc.
- Americans need to be aware that moving your 401(k) to an international fund will result in U.S. tax liability and possibly the 10% penalty for an early withdrawal.
- Withdrawing money from a traditional 401(k) before you turn 59 ½ years, can result in income taxes. Roth IRAs and Roth 401(K) withdrawals are taxed on distributions.
Steps to Transfer
- Create a Self directed (SIDRA) or Solo 401k structure. The choice of Solo 401(k) and a Self-Directed IRA (SDIRA) depends on your employment status, desired control, and overall retirement strategy.
- Open two companies (US and Portugal). SIDRA owns US LLC as sole owner with 100% ownership.
- Open two corporate bank accounts (US and Portugal).
- Authorise the transfer from SIDRA to US account and to Portugal accounts.
Please speak to your accountant or qualified expert.
A Self-Directed IRA is open to almost any investor with flexibility, while Solo 401(k) is designed specifically for self-employed individuals or business owners with no full-time employees, providing higher contribution limits and often simpler investment control.

Here’s a quick comparison to help you decide which might fit your needs best:

Tax Treaty
US and Portugal has signed a tax treaty. You are not required to pay U.S. income taxes on your Portuguese-source income. This is because the United States and Portugal have a bilateral tax treaty.
