Moving to Poland from the UK: the 2026/27 tax guide

Poland is not Dubai or Panama. A Polish tax resident is taxed on worldwide income, so the question is never whether you will pay tax in Poland but which Polish regime you land in. For an employee on the general scale, the first PLN 30,000 is free of tax, income up to PLN 120,000 is taxed at 12% and the excess at 32%. For the self-employed and business owners the picture is far better: a flat 19% on profits regardless of size, or a lump-sum tax on revenue at rates that can be lower still. Add the four-year return relief for people arriving after a spell abroad and a mid-career professional can pay strikingly little Polish tax in the early years.

None of that helps until the UK side is closed off properly. Until you are non-resident under the Statutory Residence Test, the UK taxes your worldwide income wherever you live, and a Polish registration or PESEL number changes nothing on its own. Three things have to line up: you break UK residence under the SRT, you claim split-year treatment where you leave mid-year, and you deal correctly with the income and gains that stay UK-taxable regardless of where you live. The treaty then stops the two systems taxing the same income twice.

The SRT (RDR3, GOV.UK) is applied in order: first the automatic overseas tests, which make you non-resident, then the automatic UK tests, then the sufficient ties test if neither is conclusive. For someone taking a job or starting a business in Poland, the automatic overseas tests are the target.

• First automatic overseas test: you were UK resident in one or more of the previous three tax years and spend fewer than 16 days in the UK in the current year.
• Second automatic overseas test: you were not UK resident in any of the previous three tax years and spend fewer than 46 UK days.
• Third automatic overseas test (the usual route for movers): you work full-time abroad across the tax year, broadly an average of at least 35 hours a week with no significant breaks, spend fewer than 91 days in the UK and work here on no more than 30 of those days.

If no automatic test settles it, the sufficient ties test combines your UK day count with the ties you keep: family, accommodation, work, a 90-day prior-presence tie and, for recent leavers, a country tie. The more ties you retain, the fewer UK days you are allowed. Returning Poles often keep UK ties for a transitional year or two, a spouse finishing a contract, a property not yet sold, so model your position with our SRT calculator at /tools/srt-calculator: a few days either side of a threshold can flip the answer.

Most people do not emigrate neatly on 6 April. Where the conditions are met, split-year treatment divides the tax year into a UK part, taxed on worldwide income, and an overseas part, taxed only on UK-source income, so Polish earnings after the split date fall outside UK income tax for that year. The common gateways for leavers are starting full-time work overseas and ceasing to have a UK home, each with its own timing conditions and UK day limits.

The admin is the same as for any departure. File a P85 (GOV.UK) if you are employed or have a pension, and a final Self Assessment return for your year of departure. Split-year treatment is claimed on the SA109 residence pages, not by the P85, and the SA109 cannot be filed through HMRC's own free online service, so you will generally need commercial software or an agent. Keep evidence: travel dates, your Polish employment or business registration, tenancy or purchase documents. Residence questions are argued after the fact, on paper.

Becoming non-resident does not switch off UK tax on UK-source income, and because Poland taxes residents on worldwide income, several items can be in both nets at once, with the treaty deciding who gives way. The table shows the main items.

Three further UK rules deserve their own line. First, the temporary non-residence trap: if you were UK resident in at least four of the seven tax years before leaving and return within five years, gains and certain income realised while abroad can be taxed in your year of return. Second, the residence-based IHT rules in force since 6 April 2025: if you were UK resident for at least 10 of the previous 20 tax years you are a long-term resident, and your worldwide estate stays within UK inheritance tax for a tail of up to 10 years after you leave, tapering with how long you were here. Third, voluntary National Insurance: most leavers should apply on form CF83 to keep paying Class 2 or Class 3 contributions, because a full UK State Pension is cheap to protect and expensive to rebuild, even while you build a Polish ZUS record.

Poland taxes residents on worldwide income and non-residents on Polish-source income. You are generally Polish tax resident if your centre of personal or economic interests is in Poland or you spend more than 183 days there in a year. The general scale for 2026 has two bands: 12% on income up to PLN 120,000 and 32% on the excess, with a tax-free amount of PLN 30,000 delivered through a tax-decreasing amount of PLN 3,600 (PwC Worldwide Tax Summaries, Poland).

Business income is where Poland gets interesting. A sole trader can opt out of the scale entirely and pay a flat 19% on business profits, whatever their size. Alternatively, the lump-sum tax on registered revenue (ryczalt) taxes turnover rather than profit, with no cost deductions, at activity-based rates running broadly from 2% to 17%: 12% for many IT services, 14% for medical, architectural and engineering professionals, and 8.5% for many other services. Eligibility broadly requires prior-year revenue of no more than EUR 2 million, and some activities are excluded. For a high-margin consultant the ryczalt can undercut both the scale and the 19% flat tax, but the right choice depends on margins and on Poland's health insurance contribution, which is calculated differently under each taxation form, so the comparison needs running on real numbers.

Two more rates complete the picture. A solidarity levy of 4% applies to income above PLN 1 million a year, declared separately by 30 April. And capital income, dividends, interest and gains on shares, is taxed at a flat 19% with no tax-free allowance; gains on a privately held property are generally exempt once five years have passed from the end of the calendar year of purchase.

Poland's standout offer to this corridor is the return relief, ulga na powrot. If you move your tax residence to Poland and were not Polish tax resident for at least the three preceding years, up to PLN 85,528 of qualifying income a year is exempt from Polish income tax for four consecutive tax years. It applies to employment income, contracts of mandate and business income, but it is not open to everyone: you also need Polish, EU, EEA or Swiss citizenship, a Karta Polaka, or at least three years of prior tax residence in a listed country, and the UK is on that list, so most arrivals from the UK qualify. Stacked with the PLN 30,000 tax-free amount, an employee on the scale can earn around PLN 115,528 a year before Polish income tax bites.

The relief has applied to arrivals since 2022 and remains open in 2026. You choose whether the four-year clock starts in the year you arrive or the following year, a genuine planning decision when your arrival year is split between the two countries. Documenting your prior non-residence matters, usually with a certificate of residence: the same evidence that shows HMRC you left cleanly shows the Polish authorities you qualify. Horizon advises on the UK side of the move and coordinates with a local adviser in Poland for the Polish filings and the relief claim itself.

The UK and Poland have a full double taxation convention. It entered into force on 27 December 2006 and has had effect in the UK since 6 April 2007 for income tax and capital gains tax (GOV.UK). It has been modified by the Multilateral Instrument, with the modifications taking effect from 2019, and one MLI change matters for this corridor in particular: the method Poland uses to relieve double taxation on UK income shifted, so older advice on how UK-source income lands in a Polish return may be out of date and should be rechecked against the synthesised treaty text.

For a returning professional the treaty does three jobs. Its residence tie-breaker settles which country can treat you as resident in the messy transition year. It allocates taxing rights over the UK income you keep, rental profits, pensions, dividends. And it underpins the credit that stops the same income being taxed twice. One structural warning: if you keep a UK limited company and run it from Poland, Polish management and control can drag the company itself into Polish corporate tax, so directors should take advice on both sides before assuming the company carries on as before.

Poland suits returning Polish professionals above all: the return relief was designed for them, the four-year exemption plus the 12% first band makes the landing gentle, and family and language remove the friction that derails other relocations. It also suits self-employed consultants and contractors whose numbers work under the 19% flat tax or the ryczalt, and remote employees whose pay would sit largely within the return relief in the early years.

It suits people less well if their income is dominated by investment returns, since capital income is taxed at a flat 19% from the first zloty with no equivalent relief, or if they earn far above PLN 1 million a year, where the solidarity levy adds 4%. It also does nothing for UK property income and gains, which stay in the UK net regardless, and anyone likely to return to the UK within five years should price in the temporary non-residence rules before realising gains abroad.
