Expat & Non-Resident Tax: Poland
A Chartered Tax Adviser for life between the UK and Poland
UK tax returns, residence advice and treaty planning for people moving to Poland, living there with UK income, or coming to the UK from Poland. Fixed fees, agreed first.
The Short Answer
Horizon UK Tax Solutions is a London-based Chartered Tax Adviser practice that handles the UK side of a move between the UK and Poland: the year-of-move return, your residence position, UK property and pensions you keep, and the UK-Poland treaty claims that stop the same income being taxed twice. Poland is a regime-selection move, not an escape. A Polish resident is taxed on worldwide income, so for anyone heading there the job is a clean UK exit under the Statutory Residence Test, the right treaty outcome on what stays UK-taxable, and, if you own a UK company, keeping Polish management and control from dragging it into Polish corporate tax.
The UK exit still decides most of the outcome. Split-year treatment is claimed on the SA109 pages of your return, not by the P85, and HMRC's free online service cannot file those pages. Once you are non-resident, a UK property sale must be reported, and any tax paid, within 60 days of completion, even where nothing is due. Returning Poles who keep a UK property or a working spouse in the UK should model the Statutory Residence Test before planning visits, because a few days either side of a threshold can flip the answer. We handle the UK side of each of these points and coordinate a local adviser in Poland for the Polish filings.
Everything is handled remotely from London, with year-round support and direct access to the adviser. Fees are fixed and agreed in writing before any work starts: a non-resident or expat tax return is £550, personal returns start from £350 and complex returns from £750, and advisory work such as a departure plan or a treaty review is quoted as one fixed figure upfront. There is never an hourly rate. The practice is founder-led by Jordan Onraet-Wells, a Chartered Tax Adviser with over 10 years of experience including 7 at a Big Four firm, and is rated 5.0 on Google from 19 reviews.

What We Do
Handled for you, end to end
- Your departure year: Statutory Residence Test modelling, then the Self Assessment return with the SA109 pages and split-year claim HMRC's free service cannot file
- UK property kept or sold from Poland: the NRL1 application, the annual landlord return and the 60-day Capital Gains Tax report on sale
- UK pensions under the UK-Poland treaty: government service pensions generally stay UK-taxable, the rest depend on the treaty and the disregarded-income rules, and we make the UK claim
- A UK limited company run from Poland: the dual-residence risk from Polish management and control, settled before you move, not after
- Poland's four-year return relief flagged before you move, the UK evidence of your time abroad prepared, and a vetted Polish adviser coordinated for the claim itself
- Moving to the UK from Poland: the arrival-year split-year case, the SA109, and whether the four-year FIG regime is open to you

Moving to Poland from the UK: the 2026/27 tax guide
Poland taxes residents on worldwide income at 12% and 32%, but a 19% flat rate for business income, a lump-sum option on revenue and a four-year return relief make it far friendlier than the headline bands suggest. The UK exit still decides most of the outcome.
