1. Introduction to US taxation for expats

The US is one of the few countries that taxes its citizens on worldwide income, regardless of where they live. This means that if you're an American living abroad, you still need to file a US tax return. While this can seem daunting, understanding the rules and taking advantage of various exclusions, credits, and deductions can help you manage your tax liability effectively.


2. Who needs to file US taxes?

Any US citizen or resident alien must file a US tax return if their income exceeds certain thresholds, which vary based on filing status and age. Additionally, self-employed individuals must file if their net earnings exceed $400. Even if you don’t owe any taxes, you might still need to file to claim certain credits or refunds.


3. Key tax forms for expats

Expats must be familiar with several key tax forms, including:

- Form 1040: The standard US individual income tax return.

- Form 2555: Used to claim the Foreign Earned Income Exclusion.

- Form 1116: For claiming the Foreign Tax Credit.

- FinCEN Form 114 (FBAR): Required if you have foreign bank accounts with an aggregate value exceeding $10,000 at any time during the year.

- Form 8938: Required under FATCA if you have specified foreign financial assets exceeding certain thresholds.


4. Income reporting and foreign earned income exclusion

Expats must report all income, including wages, self-employment income, and other earnings. The Foreign Earned Income Exclusion (FEIE) allows qualifying expats to exclude a certain amount of foreign-earned income from US taxation. For 2023, this amount is $120,000.

To qualify, you must meet one of two tests:

- Bona Fide Residence Test: You are a bona fide resident of a foreign country for an uninterrupted period that includes an entire tax year.

- Physical Presence Test: You are physically present in a foreign country for at least 330 full days during any 12-month period.


5. Foreign tax credit and deduction

The Foreign Tax Credit (FTC) allows you to reduce your US tax liability by the amount of foreign taxes paid or accrued. If you can't claim the full credit in one year, you can carry it back one year or forward up to ten years. Alternatively, you can claim a deduction for foreign taxes paid, though this is generally less beneficial than the credit.


6. FBAR and FATCA compliance

FBAR (Foreign Bank Account Report)

US persons with foreign financial accounts exceeding $10,000 in aggregate must file the FBAR. The deadline is April 15, with an automatic extension to October 15.


FATCA (Foreign Account Tax Compliance Act)

Under FATCA, you must report specified foreign financial assets on Form 8938 if they exceed certain thresholds. These thresholds vary based on filing status and whether you live abroad or in the US.


7. State taxes

Even if you live abroad, you may still be liable for state taxes, depending on your state of domicile. Each state has its own rules, so it's crucial to check your state's requirements and consider changing your domicile to a no-tax state if possible.


8. Retirement accounts and investments

Retirement Accounts

Contributions to US retirement accounts like IRAs and 401(k)s can be complicated for expats. You may not be able to contribute to these accounts if you exclude all of your income using the FEIE. Additionally, distributions from foreign retirement accounts might be taxable in the US.


Foreign investments can trigger additional reporting requirements and tax implications. Passive Foreign Investment Companies (PFICs) and other foreign mutual funds often have complex reporting rules and high tax rates.


9. Tax treaties

The US has tax treaties with many countries to prevent double taxation and provide other tax benefits. These treaties can affect how certain types of income are taxed and may provide exemptions or reductions in tax rates. It’s essential to understand the provisions of the relevant tax treaty between the US and your country of residence.


10. Practical tips for expats

- Keep Detailed Records: Maintain thorough records of your income, expenses, and foreign accounts.

- Stay Informed: Tax laws change frequently, so keep up-to-date with the latest rules and regulations.

- Seek Professional Help: Consider hiring a tax professional specialising in expat taxes to ensure compliance and optimise your tax situation.

- Plan for Currency Exchange Rates: Use consistent exchange rates for reporting foreign income and expenses.


11. Common pitfalls and how to avoid them

- Missing Deadlines: Ensure you meet all filing deadlines, including extensions for FBAR and FATCA.

- Ignoring State Tax Obligations: Verify your state tax responsibilities, as ignoring them can lead to penalties.

- Overlooking Foreign Tax Credits: Properly claim FTC to avoid double taxation.

- Neglecting Reporting Requirements: Failure to file FBAR or Form 8938 can result in significant penalties.


12. Next steps

Navigating US taxes as an expat can be complex, but with the right knowledge and tools, you can manage your tax obligations effectively.
