The Foreign Account Tax Compliance Act (FATCA) has had a significant impact on the financial responsibilities of US citizens living abroad, particularly those with business interests in the UK.
FATCA was enacted to combat tax evasion and imposes extensive reporting requirements on both individuals and foreign financial institutions.
What is FATCA?
FATCA is a US federal law enacted in 2010 as part of the Hiring Incentives to Restore Employment (HIRE) Act. Their main goal is to prevent tax evasion by U.S. taxpayers using foreign accounts and investments.
Main goals
- FATCA requires foreign financial institutions (FFIs) to disclose information about financial accounts of U.S. citizens.
- It requires U.S. taxpayers who have certain foreign financial assets to report them annually to the Internal Revenue Service (IRS).
- By expanding disclosure, FATCA aims to identify and prevent tax avoidance strategies associated with offshore accounts.
FATCA reporting requirements for US expats
For US expats with business interests in the UK, FATCA adds another layer of complexity to tax compliance.
Individual reporting requirements
Report thresholds
The reporting thresholds vary depending on registration status and place of residence:
- Single people living abroad:
Year-end balance: $200,000
Any time of the year: $300,000
- Marriage with shared residence abroad:
Year-end balance: $400,000
Any time of the year: $600,000
Forms to submit
To comply with FATCA, US expats must submit certain forms, often according to one Tax advice to ensure accuracy:
- Form 8938 (Statement of Specified Foreign Financial Assets):
Filed with your annual tax return.
Reports details of foreign financial assets, such as bank accounts, investment accounts, and ownership of foreign companies.
FBAR (FinCEN Form 114):
Required if the total value of foreign financial accounts exceeds $10,000 at any time during the calendar year.
Submitted electronically via the Financial Crimes Enforcement Network (FinCEN).
Impact on US expats with UK business interests
Double taxation obligations
US taxation of world income
- The United States taxes the worldwide income of its citizens, regardless of where they live. This means that income from UK business interests must be reported to the IRS.
- Profits, dividends and other income from UK companies are subject to US taxation and must be reported on the expatriate’s US tax return.
UK tax obligations
- The UK taxes individuals based on their residency status. If you are a UK resident you will be subject to UK tax on your worldwide income.
- UK companies are subject to UK corporate tax laws, which may differ significantly from US regulations.
Alleviation of double taxation
- The US-UK treaty helps prevent double taxation by allowing tax credits and exemptions. It determines which country has the right to tax certain types of income.
- US expats can claim a credit for income taxes paid to the UK, reducing their US tax liability.
- The foreign earned income exclusion allows qualified individuals to exclude a certain amount of foreign earned income from U.S. taxation.
Possible penalties
Failure to comply with FATCA can result in severe penalties.
- Failure to File Form 8938: Penalties start at $10,000, with an additional $10,000 for every 30 days of failure to file after notification by the IRS, up to a maximum of $50,000.
- Accuracy-Based Penalties: A 40% penalty may be imposed for underpayment of taxes attributable to undisclosed foreign financial assets.
- Willful Failure to Report: Willful failure to report may result in criminal penalties, including fines of up to $250,000 and imprisonment.
- Tax evasion allegations: Concealing assets or income can lead to criminal prosecution for tax evasion.
- For Foreign Payments: A 30% withholding tax may be imposed on certain U.S. source payments to non-compliant individuals or entities.
- Increased scrutiny: Non-compliance can trigger audits and investigations that can damage personal and professional reputation.
- Business disruption: Legal issues and fines can disrupt business operations and strain resources.
Mitigate the impact of FATCA
Tax planning strategies
Proper tax planning is critical to minimizing the impact of FATCA and maximizing the benefits available under both US and UK tax laws.
Foreign Earned Income Exclusion (FEIE)
The FEIE allows qualified U.S. expats to exclude up to $112,000 (for 2022) of foreign earned income from U.S. taxation. This exclusion can be an effective tool for those who have significant income from UK sources.
To qualify, expats must pass the bona fide residency test or the physical presence test. Proper documentation is essential to prove eligibility.
Exclusion of expatriate accommodation
US expats can exclude certain overseas housing costs from their income, including rent, utilities and insurance. The exclusion is in addition to the FEIE and can significantly reduce taxable income.
For expats living in expensive cities like London, excluding housing abroad can mean a significant tax break.
Foreign Tax Credit (FTC)
The FTC allows expats to claim a dollar-for-dollar credit for foreign taxes paid to the UK, thereby reducing their US tax liability. This credit is particularly useful if income is taxed at a higher rate in the UK than in the US.
The FTC has limitations and may not be able to fully offset U.S. taxes in all cases. However, unused credits can often be carried forward to future tax years.
Plan your retirement
Tax treatment of UK pensions
The tax treatment of UK pensions, such as self-invested personal pensions (SIPPs) and workplace pensions, can be complex under US tax law. Contributions, growth and distributions may have different tax implications.
The US-UK tax treaty provides special provisions for the taxation of pensions, which often allow for tax deferral similar to qualified US retirement accounts.
Roth IRAs and ISAs
While Roth IRAs provide tax-free growth under US law, their treatment may be different under UK tax law. Conversely, Individual Savings Accounts (ISAs) are tax-free in the UK but taxable in the US.
Social security contracts
The US-UK Totalization Agreement prevents double taxation of Social Security and helps determine eligibility for benefits.
Conclusion
FATCA presents significant challenges for US expats with business interests in the UK, but with strategic planning it is possible to effectively manage these complexities. By leveraging tax treaties, taking advantage of appropriate exclusions and credits, and engaging in proactive retirement and estate planning, expats can mitigate the impact of FATCA and optimize their financial outcomes.
Understanding the implications of FATCA is critical not only to ensuring compliance, but also to making informed decisions that comply with both US and UK tax laws.
Working with experienced tax and legal professionals, staying abreast of regulatory changes, and regularly reviewing financial strategies are important steps to successfully managing your global tax responsibilities.
