Why Recent UK Tax Changes Are Prompting US Expats to Re-evaluate Their Residency

The recent changes in UK tax regulations have left many US expats considering drastic measures, including relocating to avoid potential financial pitfalls. For US citizens living abroad, tax compliance is already a complex web of UK and US obligations. However, new UK policies and existing US tax requirements have intensified concerns about double taxation, residency status, and overall tax liability.

Let’s explore the implications of these changes, examine typical scenarios, and examine worst-case outcomes to help you understand the stakes and available strategies.

The updates primarily focus on:

  • Dividend and Capital Gains Tax Changes: Reductions in tax-free allowances on dividend and capital gains income, are set to shrink further in future years.

  • Inheritance Tax Clarity: Proposals to tighten exemptions for non-UK domiciles, potentially impacting long-term US expats.

  • Increased HMRC Scrutiny: Heightened enforcement and audit rates, especially targeting high-net-worth individuals and those with cross-border tax arrangements.

For US expats, these changes can trigger higher overall tax liabilities due to overlaps with US taxation under FATCA (Foreign Account Tax Compliance Act) and double taxation treaties.

Common Concerns Among US Expats

  1. Double Taxation Risk: Even with the US-UK tax treaty, recent changes could create instances where credits don’t fully offset liabilities.

  2. Loss of Tax Efficiency: Investment income and capital gains may now face more immediate or higher taxation.

  3. Complexity in Filing: Increased compliance requirements lead to higher costs for professional advice.

Case Studies: The Impact on Residency Decisions

Case Study 1: Worst-Case Scenario

Profile: Emily, a US expat in the UK for 15 years, earns £120,000 annually with £20,000 in dividends and £50,000 in capital gains from US investments.

  • Before Changes: Emily relied on the UK’s capital gains tax-free allowance to minimize her liability and used US Foreign Tax Credits to offset the rest.

  • After Changes: Her UK capital gains tax allowance has dropped significantly, leaving her with a £10,000 taxable gain in the UK that her US tax credits don’t fully cover.

  • Outcome: Emily’s effective tax rate on investment income rises to 42%. She is considering a move to Portugal to benefit from its favourable expat tax regime under the Non-Habitual Residency scheme.

 

Case Study 2: Typical Scenario


Profile: John and Susan, dual-income US expats with a combined UK income of £200,000, own a small rental property in the US.

  • Before Changes: The couple managed their taxes through the UK-US treaty, ensuring their foreign rental income was taxed only once.

  • After Changes: Reduced allowances on dividends and stricter UK residency rules mean higher compliance costs and a marginally increased tax liability.

  • Outcome: They remain in the UK but explore tax restructuring options, such as gifting assets to their US-based children.

 

Why Are Expats Considering Relocation?

The UK’s tightening tax regime could diminish its attractiveness compared to countries like:

• Portugal: Favorable income tax rates and exemptions for foreign pensions under the Non-Habitual Residency scheme.

• Ireland: Lower dividend tax rates for expats in certain brackets.

• Dubai: No income or capital gains tax for foreign residents.

For many US expats, these alternatives provide a chance to protect wealth and simplify compliance obligations.
