Tax solutions for US citizens in the UK

Welcome to Rouse, a west of London, award-winning firm of accountants and tax advisors.

Our team are experienced in helping US citizens and expatriates in the UK, from completing their UK tax filings, advising on UK residency status and providing tax advice.

Please note: We provide a UK tax service for US expatriates living in the UK. If you also require US tax filings (in addition to your UK tax filing) we can introduce you to firms we work closely with who can assist. Alternatively, if you already have a tax advisor in the US, we are equally happy to liaise with them.

What are my tax responsibilities as a US expat in the UK?

UK tax responsibilities

Whilst living in the UK, depending on your circumstances, you will be required to report and pay tax:

  • Through your PAYE salary – If you will be working as an employee, you will be subject to Pay As You Earn (PAYE) tax, which will also apply if you are being paid from outside of the UK. When moving to the UK, your employer will need to submit a “Starter Declaration” to HMRC as part of the monthly online payroll reporting. This will provide certain personal information details, including your start date, address, date of birth and number of hours per week that you expect to work. HMRC will then issue a tax code to you and a copy to your employer which will then be used to determine the total amount of tax to withhold each pay period.
  • Through your self-assessment tax return – If you meet any of the following criteria at any point during the tax year, you will be required to complete a self-assessment tax return. We can prepare your UK tax return on your behalf and provide advice with regards to tax planning to minimise your UK tax liability.
  • Are you claiming non-resident or non-domicile status?
  • Are you self-employed, a company director or a partner in a business?
  • Did you receive income over £100,000?
  • Did you receive £10,000 or more from taxed savings and investments?
  • Did you receive more than £2,500 in untaxed income?
  • Did you receive income from letting out property?
  • Did you receive foreign income liable to UK tax?
  • Are you an employee claiming expenses or professional subscriptions of £2,500 or more?

US tax responsibilities

If, while you are living in the UK, you remain a citizen or permanent resident of the United States, then you will need to file a US tax return based on your worldwide income with the US federal government each year.

In addition to the income tax return, you may be required to file further informational returns based on assets held outside the US.

To avoid double taxation, the US government does offer a number of special provisions and exclusions, which if used correctly, can minimise or in some cases eliminate the tax due.

Where we are providing UK tax services, we can also introduce clients to tax advisors who can assist with their US tax filing needs.

How can we help?

Our services include:

  • Completing your self-assessment tax return, including applying split year treatment if necessary
  • Tax planning advice
  • Advising on your UK residency and non-domicile status
  • Performing all tax calculations and checking your tax codes
  • Dealing with HMRC on your behalf
  • Advising on trusts, property or inheritance tax planning

Whilst we do not provide a US tax return service, we can introduce clients to our contacts who can assist with their US tax filing needs, alongside our UK tax service.
