Expat & Non-Resident Tax
A Chartered Tax Adviser for UK expats, wherever you are
UK tax returns, residency advice and cross-border planning for expats and non-residents, handled personally, on fixed fees agreed before any work starts.
The Short Answer
Horizon UK Tax Solutions is a specialist UK expat tax adviser: a Chartered Tax Adviser (CTA) practice handling UK tax returns, residency and planning for British expats, non-residents and internationally mobile families in every time zone. You work directly with the founder, a CTA with over 10 years of experience including 7 at a Big Four firm, not a call centre or a junior you have never met.
The work covers everything a life abroad touches: Self Assessment returns with the SA109 residence pages that HMRC’s free online service cannot file, the Statutory Residence Test and split-year claims, non-resident landlord income, Capital Gains Tax on UK property sales with its 60-day reporting deadline, double taxation relief, and the planning around a departure or a return.
Fees are fixed and agreed in writing before any work starts, with non-resident and expat returns from £550, and the practice is rated 5.0 on Google by clients across six continents. If you are comparing advisers, start with the free 30-minute clarity call and see the difference direct access makes.
