Residence and Domicile, Streamlined Procedures, and International Tax Accountant UK: Navigating US Tax Requirements for US Expats in the UK

For US expatriates living in the United Kingdom, understanding the complex world of international tax regulations is a critical part of financial planning. This article, presented by Xerxes Associates LLP, a leading UK and US tax advisory firm, explores the concepts of residence and domicile, streamlined procedures, and the vital role of international tax accountants in ensuring compliance with US tax requirements.

Residence and Domicile

To comprehend the intricacies of US tax requirements for expats in the UK, one must first grasp the concepts of "residence" and "domicile." These terms play a pivotal role in determining an individual’s tax obligations in both countries.

Residence: In the US, taxation is primarily based on an individual’s status as a resident or non-resident. US citizens and green card holders are subject to US taxes on their worldwide income, regardless of where they reside. Expats, on the other hand, may qualify for special tax provisions, such as the Foreign Earned Income Exclusion (FEIE) or the Foreign Tax Credit (FTC), depending on their residence status.

Domicile: Domicile refers to an individual’s permanent home, the place they intend to return to and establish their life. Establishing domicile in the UK may have implications for an expat’s inheritance tax liability, among other considerations. Understanding how domicile is determined and how it affects tax liability is crucial.

Streamlined Procedures

US expatriates often find themselves facing challenges related to past compliance, especially when they have not been aware of their tax obligations. Fortunately, the Streamlined Filing Compliance Procedures offer a solution to this common problem. These procedures allow eligible expats to catch up on their unfiled tax returns and foreign bank account reporting without facing excessive penalties.

Key points about the Streamlined Procedures:

Eligibility: To qualify, expats must meet non-residency requirements, meaning they must have lived outside the US for a specific period. The Streamlined Procedures are a valuable option for those who wish to rectify previous non-compliance.

Compliance Process: The process involves filing amended tax returns for the previous three years and filing FBAR reports for the previous six years. There are also required certifications and documentation to be submitted.
