Relocating Internationally

Relocating abroad is often framed as a personal lifestyle decision. But financially, it is a major reallocation event. Your tax status changes. Your account access changes. Your currency exposure changes. And your ability to manage investments changes. Planning for these shifts prevents expensive mistakes.

Key takeaways

• Tax residency (not citizenship) determines which country's tax authorities have claim to your income. Moving abroad usually changes your tax residency, even if you remain a citizen.
• Many investments and accounts available at home are unavailable or restricted abroad (US-based IRAs cannot be accessed as easily from the UK; many US brokers will not service non-residents).
• US citizens abroad must file US tax returns on worldwide income and report foreign accounts (FATCA, FBAR), even if they also pay taxes to their new country—this creates a double-reporting burden.
• Currency risk becomes material: if you move to another currency zone, your investments and future income may be in different currencies, creating exchange rate exposure.
• Planning the timing of the move (before or after an account distribution, tax-loss harvesting opportunity, or income event) can reduce the tax bill significantly.

Tax residency versus citizenship

Tax residency and citizenship are different.

Citizenship is your legal status—your passport. If you are a US citizen, you remain a US citizen even if you move to Australia. Citizenship is hard to change and requires formal renunciation in most countries.

Tax residency is determined by where you live and where your economic ties are. It changes when you move. If you live in the US for most of the year and have a job and a home in the US, you are a US tax resident. If you move to Canada and live there for most of the year, you become a Canadian tax resident (and cease to be a US resident).

For tax purposes, moving abroad means you are changing your tax residency. This has several consequences:

1. Different tax system: You now owe taxes to your new country (based on its laws, rates, and rules).
2. Different filing obligations: You may have to file in both countries, or report foreign income to your home country.
3. Different account restrictions: Your home country's tax authorities may restrict your access to certain accounts, or require their citizens/residents abroad to report foreign holdings.

The US citizen abroad situation

The US is unusual in that it taxes its citizens on worldwide income, regardless of where they live. If you are a US citizen and you move to Germany, you still owe US tax on your US-source income and (with some exceptions) your German income.

This creates several complications:

FATCA (Foreign Account Tax Compliance Act): US citizens abroad must report foreign financial accounts to the US if they have more than $10,000 in aggregate. The report is called an FBAR (Foreign Bank Account Report). Failure to file is a serious penalty (up to $100,000 per account, per year).

Double taxation risk: You might owe tax to both the US and your new country. If you earn €50,000 in Germany and pay 40% German tax, you owe €20,000 to Germany. But the US says you owe federal tax on that €50,000 too. To avoid double taxation, the US allows a Foreign Earned Income Exclusion (up to $120,000 in 2023) and a foreign tax credit (credit for taxes paid to another country). But these are complex and require careful filing.

Brokerage access: Many US brokers (Fidelity, Vanguard, Charles Schwab) will not service non-US residents. Once you move abroad, you may lose access to your accounts or be forced to move to a different broker.

IRA complications: A traditional IRA or Roth IRA opened in the US cannot easily be accessed from abroad. Distributions become taxable and subject to FBAR reporting. If you need to convert a traditional IRA to a Roth while abroad, the pro-rata rule (from earlier in this chapter) applies and can create a large tax surprise.

Planning the move: the pre-move checklist

If you are planning to move abroad, execute these steps before you leave:

1. Consolidate accounts: If you have multiple IRAs, 401(k)s, or brokerage accounts, consolidate them into one or two accounts. This simplifies FBAR filing and reduces the chance of losing track of an account.

2. Understand your new country's taxation: You will now owe taxes there. Learn the filing deadlines, the rate structure, and whether you can use US tax credits or exclusions to avoid double taxation. Hire a tax advisor who specializes in expat taxation; this is not optional.

3. Review account access: Call your brokers and ask: if I move to [country], can I still manage my accounts? Some brokers will let you stay if you maintain a US mailing address; others will close the account. Know this before you arrive.

4. Plan timing of large transactions: If you are going to sell appreciated investments, harvest losses, or take a distribution, do it before you move, while you are still a US resident. Post-move, the timing of transactions becomes complicated and the tax filing becomes more complex.

5. Establish a paper trail: Keep documentation of your move: lease, utility bills, employment letter, proof of residency in the new country. This is evidence of your tax residency, and you may need it in a dispute.

6. Update beneficiary designations: Make sure your IRA and 401(k) beneficiaries are current. International complications with estates are expensive.

Currency risk and allocation

When you move abroad, you are now earning income (salary, pension, investments) in a new currency while potentially holding investments in your home currency.

Example: You move to the UK, earning GBP 60,000 per year. But your US brokerage account holds US stocks valued in USD. If GBP weakens against USD, your UK salary buys fewer dollars, and your purchasing power (in the UK) declines.

This is currency risk, and it cuts two ways:

• If your salary is in GBP and your investments are in USD, and GBP weakens, your GBP salary buys fewer USD-denominated investments.
• Conversely, if you are saving to return to the US someday, and USD strengthens, your home currency gets cheaper.

There are ways to manage this:

1. Match your income and expenses: If you earn in GBP and spend in GBP, hold most of your investments in GBP-denominated assets. This is a natural hedge.

2. Currency-hedged funds: Some investment funds are "hedged," meaning they neutralize the effect of currency movement. A "GBP-hedged MSCI World Index fund" gives you global stock exposure while limiting currency risk.

3. Home-currency tilt: Some expats keep part of their portfolio in home-currency investments (for a future return) and part in local-currency investments (for current spending). The split depends on your timeline and plans.

4. Currency as an allocation: Some expats deliberately take currency exposure, banking on a particular direction. This is speculation, not investing, and is generally not recommended.

The simplest approach: match your income and spending currency as much as possible, and hold your long-term investments in a currency that aligns with your horizon. If you plan to retire in the UK and spend in GBP, gradually shift your portfolio to GBP exposure as you approach retirement.

Account restrictions and alternatives

If your home country broker closes your account, you need alternatives:

Interactive Brokers: One of the few US brokers that will service non-US residents. Commissions are lower than retail brokers (good), but the platform is more complex (challenging for beginners).

Local brokers: Your new country's brokers and banks usually offer investment accounts. The investment options and fees vary widely. In the UK, a stocks and shares ISA is a tax-efficient account similar to an IRA. In Canada, a TFSA is similar. In Germany, most people use the local savings bank.

Home-country retirement account alternatives: If you have a 401(k) with a former employer, you might be able to leave it behind (as described in Chapter 6). You cannot contribute to it (you are no longer employed there), but you can let it grow. The FBAR reporting is still required, but the account stays accessible. This is often simpler than trying to manage an IRA from abroad.

Tax-efficient relocation timing

The date you move matters for taxes. Suppose you live in the US and you have a 401(k) with $200,000 and an IRA with $50,000. Your employer's 401(k) is about to make a distribution (after-year-end cleanup) of dividends worth $5,000. You plan to move to Australia in January.

Option 1: Stay in the US through the distribution (January), then move. You receive the $5,000 distribution in the US, it is taxable as US-source income at US rates, and you move clean.

Option 2: Move before the distribution. The distribution arrives in Australia, where you are now tax-resident. It might be subject to Australian tax, and the FBAR reporting becomes complex.

Option 1 is cleaner. The principle: time large transactions (distributions, rebalancing sales, Roth conversions) to happen in your home country before the move, when the tax treatment is simple.

Returning home: repatriation and reintegration

If you move abroad for a few years and then return, your accounts and taxes untangle slowly. If you have been filing as a non-resident, you revert to resident status. If you have foreign accounts, you continue to report them if you still have assets abroad.

The good news: moving back is generally simpler than moving out, because you return to a simpler tax situation.
