Stress-free Self Assessment
for non-UK domiciled clients

We prepare Self Assessment tax returns for internationally mobile individuals, including SA109 residence pages, split-year and treaty claims, current foreign income and gains (FIG) regime claims where eligibility is established, historic pre-6 April 2025 remittance-basis matters, and foreign income and gains reporting with double tax relief claims and DT-Individual forms.
Personal tax return help for non-dom UK taxpayers

Whether you are arriving in, leaving, or living between countries, your UK tax position depends on the Statutory Residence Test and the rules applying to foreign income and gains. From 6 April 2025 the four-year FIG regime replaced the remittance basis. We can assess a current FIG claim for a qualifying new resident and deal with historic pre-6 April 2025 remittance-basis returns, legacy foreign income or gains and relevant transitional provisions. Eligibility and treatment depend on the tax year and your circumstances.

We also bring your global picture into focus: bank interest, dividends and portfolios, rental properties, self-employment and business profits, as well as capital gains on offshore disposals. We prepare the calculations, claim UK double tax relief where available, and complete DT-Individual and other treaty paperwork so income isn’t taxed twice. If your year involves split-year treatment, temporary non-residence considerations, or complex remittances, we’ll structure your timeline and supporting evidence to align with HMRC guidance.

Personal tax returns & non-dom support FAQ's

  • Do I need to file SA109 if I’m a UK resident all year?
    SA109 is used where residence, split-year, treaty, non-residence or FIG-regime matters need to be reported. It may also be relevant when dealing with a historic pre-6 April 2025 remittance-basis position. The pages required depend on the tax year and your circumstances.
  • Does the remittance basis charge (RBC) still apply?
    The remittance basis and RBC ceased to be available for current claims from 6 April 2025, when the four-year FIG regime replaced the remittance basis. RBC and deemed-domicile analysis can still be relevant to pre-6 April 2025 returns and legacy or transitional matters. We confirm the applicable tax year and facts before advising.
  • Can I avoid double taxation on my foreign income?
    Usually yes—through treaty reliefs or unilateral relief. We prepare the necessary computations and DT-Individual/treaty forms so that eligible foreign tax can be credited against UK tax due.
