Tax Matters When British Citizens Move to the United States

 Moving from the UK to the United States is an exciting opportunity for career advancement, lifestyle change, or personal reasons. However, before making the leap, it’s essential to understand the tax implications you’ll face on both sides of the Atlantic. As a British citizen relocating to the US, you’ll have obligations to both the UK’s HM Revenue & Customs (HMRC) and the US’s Internal Revenue Service (IRS), which can make tax planning more complex than expected.

One of the key considerations is your tax residency status. Once you establish residency in the US, you may still be liable for UK taxes on certain income, particularly if you continue to have assets, investments, or property in the UK. The UK has a Statutory Residence Test, which helps determine if you are still a UK tax resident after leaving. In addition, even if you are no longer a UK tax resident, income from UK sources like rental properties will still be subject to UK tax.

On the US side, the IRS taxes US residents on their worldwide income, meaning income earned both in the US and abroad will be taxed. The US-UK Tax Treaty exists to prevent double taxation, but careful planning is required to ensure you meet your tax obligations in both countries without paying twice on the same income.

Furthermore, tax regulations differ significantly between the two countries, including differences in tax rates, allowances, and reporting obligations. For example, the IRS requires foreign bank account reporting (FBAR) and may tax UK pensions differently than HMRC. Understanding these tax considerations early on will help ensure a smooth financial transition to life in the United States.

Americans With UK Limited Companies: If You Don’t File Form 5471, Here’s What Happens

US • UK • CROSS-BORDER TAX Summary: Many Americans who set up a UK limited company are told they don’t need to file Form 5471 . That advice is dangerously wrong. The IRS treats most UK companies owned by US persons as Controlled Foreign Corporations (CFCs), triggering Form 5471, Subpart F exposure, and potential GILTI taxation , even when no money is distributed. Form 5471 applies far more often than Americans are told CFC status can create GILTI tax on retained UK profits Penalties apply even if no US tax was owed The Myth Americans Keep Hearing Some accountants claim a UK Limited Company “keeps tax offshore” or “is treated separately so the IRS doesn’t care.” That’s not just wrong, it’s financially dangerous.
