The short answer: worldwide taxation with a genuine nomad carve-out
Croatia taxes its residents on worldwide income, so this is not a territorial or non-dom play. What it offers is moderate, predictable taxation (flat 12% on most investment income, a two-year holding exemption on many capital gains) plus one genuinely unusual feature: a digital nomad residence permit that exempts qualifying remote-work income from Croatian income tax while you hold it. UK citizens are third-country nationals since Brexit, which is exactly who the permit is designed for.
But the deciding factor for your UK bill is not your Croatian permit or your apartment in Split. It is the UK Statutory Residence Test (RDR3, GOV.UK), which decides, year by year, whether the UK can still tax your worldwide income. Three things have to line up: breaking UK residence under the SRT, claiming split-year treatment where you leave mid-year, and dealing properly with the income and gains that stay UK-taxable regardless. Get those right and the Croatian position takes over.
Breaking UK residence: the Statutory Residence Test
The SRT is applied in order: first the automatic overseas tests (which make you non-resident), then the automatic UK tests (which make you resident), then the sufficient ties test if neither is conclusive. For someone moving to Croatia, 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 you cannot meet an automatic overseas test, 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. Croatia's flight connections make casual UK trips easy, which is how people drift over a threshold.

Split year, the P85 and your final tax return
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 income arising in Croatia after the split date is 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 conditions on timing and UK day limits. Remote work under the nomad permit can still count as full-time work overseas; what matters is where the work is physically done.
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 records of travel dates, work patterns and your Croatian accommodation: residence questions are evidenced after the fact.
What the UK keeps taxing after you go
Becoming non-resident does not switch off UK tax on UK-source income. Because Croatia taxes residents on worldwide income, some of it also enters the Croatian net, with the treaty deciding who has first claim and who gives credit.
| Income or gain | UK position after you leave | Croatia position as a Croatian tax resident |
|---|---|---|
| UK rental profits on a kept property | UK-taxable; [Non-Resident Landlord Scheme](/guides/non-resident-landlord-tax) withholding unless HMRC approves gross payment | Also within the Croatian net as property income, with treaty credit for UK tax paid |
| Gains on UK property | NRCGT: report and pay within [60 days](/guides/cgt-60-day-reporting-non-residents) of completion; 18% or 24% after the £3,000 annual exempt amount | Generally outside Croatian tax if you owned the property for more than two years; within two years, taxed at 24% with treaty credit |
| UK government service pensions | Generally remain UK-taxable wherever you live | Treaty rules generally leave taxing rights with the UK |
| Other UK pensions, dividends and interest | Position depends on the treaty and the disregarded-income rules; take advice | Pensions per the treaty article; dividends and interest taxed at flat 12% |
| Salary for remote work physically done in Croatia | Outside UK tax once residence is properly broken | Municipal progressive rates (broadly 15% to 23%, then 25% to 33% above EUR 60,000), or exempt under the digital nomad permit if for a foreign employer |
| Worldwide estate on death | IHT tail of up to 10 years for long-term UK residents | No Croatian equivalent of the UK tail; local succession rules are separate |
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. An 18-month nomad permit stay is well inside that window. Second, the residence-based IHT rules that took effect on 6 April 2025: if you were UK resident for at least 10 of the previous 20 tax years, your worldwide estate stays within UK inheritance tax for a tail of up to 10 years after you leave. 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.
Croatia's income tax after the 2024 reform, verified
Croatia reformed its income tax from 2024, abolishing the separate city surtax and instead letting every local self-government unit set its own two progressive rates within national ranges. Annual income (employment, self-employment and other income) is split at EUR 60,000: municipalities may set the lower-bracket rate between 15% and 20%, towns up to 21%, large cities and county seats up to 22% and Zagreb up to 23%, with the higher bracket running from 25% up to 30%, 31%, 32% and 33% respectively. Where a local unit makes no choice, default rates of 20% and 30% apply. Zagreb sits at the top of the permitted ranges, so where you register matters to your rate.
Investment and property income is taxed separately at flat final rates: dividends 12%, interest 12%, and capital gains on financial assets 12%, with gains on financial assets held for more than two years outside the charge. Rental income is taxed at 12% after a 30% lump-sum expense deduction. Gains on real estate are taxed at 24%, but a sale is exempt once you have owned the property for more than two years, or where it was used as your or your immediate family's home, while a pattern of more than three properties of the same type sold in five years brings the gains back into charge. You generally become Croatian tax resident once you have a home at your disposal there for at least 183 days (whether or not you occupy it) or you are physically present for at least 183 days across one or two calendar years, at which point worldwide income is in scope.
The honest boundary: Horizon advises on the UK side of the move and coordinates with a local adviser in Croatia for local filings and immigration. The Croatian figures above are verified against current professional summaries (PwC Worldwide Tax Summaries: Croatia), but your own Croatian registrations and returns belong with local counsel.
The digital nomad permit and its income tax exemption
Croatia introduced a digital nomad residence permit in January 2021 and paired it with a statutory income tax exemption: income earned by a permit holder from employment or self-employment carried out remotely for an employer or their own company not registered in Croatia is exempt from Croatian income tax under Article 9 of the Croatian Income Tax Act. It is a legislative exemption and applies even where your stay would otherwise make you taxable in Croatia.
- Who it covers: third-country nationals, which includes UK citizens, working through communication technology for a foreign employer or their own non-Croatian company, and not providing services to Croatian employers or clients.
- Duration: up to 18 months since changes to the foreigners legislation took effect on 15 March 2025 (previously 12 months). The permit is not renewable back to back; expect a gap of around six months outside Croatia before a fresh application.
- Income requirement: a minimum monthly income set at 2.5 times the average Croatian net salary and indexed each year, EUR 3,622.50 a month for 2026 (plus 10% per accompanying family member), evidenced by payslips or bank statements. Check the current figure with the Croatian authorities before applying.
- The boundary: any work for a Croatian employer or Croatian clients falls outside the exemption and back into the normal municipal progressive rates.
For the UK analysis, the permit changes nothing by itself: UK residence is always settled by the SRT. Because the permit is time-limited, treat it as a bridge, not a destination. If you will stay beyond it, plan for ordinary Croatian rates from the outset; if you will return to the UK, plan around the five-year temporary non-residence rule. Our digital nomad tax guide covers the UK mechanics in detail.
The UK-Croatia treaty
A full UK-Croatia double taxation agreement exists and is in force. The 2015 convention entered into force on 19 November 2015 and has had effect in the UK since 6 April 2016 for income tax and capital gains tax (and in Croatia from 1 January 2016), replacing the old 1981 UK-Yugoslavia convention (GOV.UK). It has been modified by the Multilateral Instrument, with effect in the UK from 2022.
In practice the treaty matters in three places. Its residence tie-breaker settles the position if both countries claim you in the crossover year, which is common where a UK home lingers. Its income articles allocate taxing rights over the UK-source income you keep. And its relief article underpins the double tax relief credit so the same income is not taxed twice in full. Treaty claims are made on the SA109, so keep the paperwork tidy from year one.
Who the move genuinely suits
Croatia suits remote workers with a foreign employer or their own non-Croatian company who want an EU, Eurozone, Adriatic base and can use the 18-month nomad exemption while they decide whether the move is permanent. It also suits investors and semi-retired movers whose returns are dividend and portfolio led, because flat 12% rates and the two-year exemption on financial-asset gains compare well with UK dividend and CGT rates, and long-stay movers who accept ordinary Croatian rates in exchange for a lower cost of living.
It suits people less well if their income will come from Croatian clients or employment in a high-rate municipality like Zagreb, if they expect to return to the UK within five years with significant gains to realise, or if their real aim is UK IHT protection on a short timeline, given the 10-year residence-based tail. And like every destination in this series, Croatia does nothing for UK property income and gains, which stay UK-taxable regardless.
