OOfficial 2026 guidance from tax specialists highlights the ongoing complexity American expats face when managing retirement accounts abroad. While the focus has been on Australian superannuation funds, the underlying IRS reporting requirements apply to all US citizens with foreign financial assets — including those managing 401(k)s and IRAs from Europe.
The key challenge for American expats is understanding which accounts trigger reporting obligations and at what thresholds. These requirements exist regardless of whether the income is actually taxable in the US, creating a compliance burden that catches many expatriates off guard.
Fidelity, Schwab and Vanguard: what changes when you leave the US
US search traffic to this topic clusters around one frustration: a major US broker tells you they can no longer service your address. The three names that come up most often are Fidelity, Schwab and Vanguard. The details differ by firm and product line, but the pattern is the same. Once you are tax-resident outside the United States, many US retail platforms treat you as a non-resident client. That can mean restricted trading, forced liquidation, or an account closure notice with a short deadline.
Fidelity
Fidelity’s retail brokerage is aimed at US residents. If you move abroad and update your address to a foreign country, Fidelity may limit new purchases, block certain fund types, or ask you to transfer assets elsewhere. Fidelity International is a separate business; holding a US Fidelity account does not automatically give you a compliant offshore brokerage stack. Before you move, download statements, confirm cost basis records, and ask in writing what happens to IRAs and 401(k) plans left at Fidelity if your profile shows a non-US address.
Charles Schwab
Schwab has historically been more workable for some expats than Vanguard, but it is not universal. Schwab may still close or restrict accounts when residency changes, especially where compliance teams flag FATCA reporting burden. Schwab’s international arm (where available) is not a drop-in replacement for a US Schwab login. Treat any “you can keep the account” answer as product-specific: taxable brokerage, IRA, and employer plan rules do not all move together.
Vanguard
Vanguard is often the strictest for non-residents. Many expats report being told to sell US-domiciled funds and transfer cash because Vanguard will not maintain a taxable account for someone with a foreign address. That creates a timing problem: you may owe US tax on gains in the year of departure, and you still need a replacement custodian that accepts Americans abroad without selling you PFIC-heavy funds.
Practical alternatives (not an endorsement list)
Expats typically route around the restriction rather than fight it: keep US retirement accounts at the original custodian where the plan document allows it; use an expat-friendly US broker that still accepts your country (policies change, so verify); or hold a regulated offshore/international platform designed for US persons. Each path has trade-offs on fees, fund access, PFIC risk, and estate planning. Match the broker to the wrapper (taxable vs IRA vs 401(k)) before moving large balances.
FBAR Reporting: The $10,000 Threshold
For Foreign Bank Account Report (FBAR) purposes, US citizens must file FinCEN Form 114 if their combined foreign financial accounts exceed $10,000 at any point during the year. This relatively low threshold means that most American expats with meaningful savings abroad will need to file.
The $10,000 limit applies to the aggregate value of all foreign accounts, not individual accounts. For Americans in Europe, this typically includes local bank accounts, investment accounts, and certain types of European pension arrangements. The reporting requirement exists even if the accounts generate no taxable income.
FATCA Reporting: Higher Thresholds, Greater Complexity
Form 8938 under the Foreign Account Tax Compliance Act (FATCA) has higher thresholds but broader scope. Single filers living abroad must report if their foreign financial assets exceed $200,000 at year-end, while married couples filing jointly face a $400,000 threshold.
These thresholds are significantly higher than FBAR requirements, but FATCA reporting captures a wider range of assets beyond traditional bank accounts. For American expats in Europe, this often includes local investment bonds, certain insurance products, and retirement savings vehicles.
The Challenge of Managing US Accounts from Europe
Many American expats discover that maintaining US-based retirement accounts becomes increasingly difficult after relocating to Europe. Major brokers like Schwab, Fidelity, and Vanguard often restrict services for overseas residents, limiting investment options or requiring account transfers.
This creates a practical dilemma: keeping assets in familiar US accounts that become harder to manage, or moving funds to European institutions that may trigger additional reporting requirements. The complexity is compounded by varying tax treaties between the US and different European countries.
For Americans managing substantial retirement assets, working with a dual-licensed adviser who understands both US tax law and European regulations can provide clarity on reporting obligations while maintaining investment flexibility. Proper retirement planning for expats requires navigating these dual reporting requirements from the outset.
Penalties for Non-Compliance
The consequences of failing to meet these reporting requirements can be severe. FBAR violations can result in penalties of up to $16,536 per annual report for non-willful violations, while willful violations can trigger penalties of up to 50% of the account balance. FATCA penalties start at $10,000 for failing to file Form 8938.
These penalties underscore the importance of understanding reporting obligations before relocating assets or establishing new accounts in Europe. Many American expats benefit from consolidating their financial arrangements to simplify compliance while maintaining access to appropriate investment options.
