Cyprus-UK Tax Treaty Mechanics in 2026: Post-Brexit and Post Non-Dom

For more than fifty years, tax planning between the United Kingdom and Cyprus has rested on a single bilateral instrument and on whatever EU framework happened to sit alongside it. In 2026, after Brexit and after the abolition of the UK non-dom regime, only the bilateral instrument remains - the 2018 Convention - and it carries more weight than ever. This guide walks through what the treaty actually does in 2026, how it interacts with the UK Statutory Residence Test and the Cyprus 60-day rule, and what changed for pensions, capital gains and corporate cross-border flows.

The 2018 Cyprus-UK Convention at a glance

The current treaty is the "Convention between the Government of the United Kingdom of Great Britain and Northern Ireland and the Government of the Republic of Cyprus for the Elimination of Double Taxation with respect to Taxes on Income and on Capital Gains and the Prevention of Tax Evasion and Avoidance", signed in Nicosia on 22 March 2018.UK-Cyprus Double Taxation Convention, signed 22 March 2018, in force 18 July 2018It entered into force on 18 July 2018 and is effective for Cyprus tax purposes from 1 January 2019 and for UK income tax and CGT purposes from 6 April 2019 (1 April 2019 for UK corporation tax). It replaced the 1974 treaty in its entirety.

It is a modern, BEPS-influenced instrument with a Principal Purpose Test (PPT), OECD-aligned exchange-of-information provisions and mutual-agreement procedures. It sits entirely outside the EU framework and was unaffected by the UK's withdrawal.

Withholding tax rates: dividends, interest, royalties

The headline rates under the Convention, applied where the recipient is the beneficial owner and is resident in the other contracting state, are summarised below.

Note the Brexit shift. Until 31 December 2020, an interest or royalty payment from a UK company to a 25%+ EU parent could often rely on the Interest & Royalties Directive to reach 0%. From 1 January 2021 that route closed and taxpayers must invoke the Convention directly. UK paying entities will typically require a Cyprus tax-residency certificate and treaty-relief claim before reducing withholding at source.

For dividends from Cyprus to the UK, Cyprus imposes no domestic withholding tax on outbound dividends to non-resident shareholders. See our note on the 17% SDC trap on intra-Cyprus dividend flows.

Capital gains and the immovable-property carve-out

Article 13 of the 2018 Convention follows the OECD Model. Gains on immovable property are taxable in the state where the property is situated; gains on shares deriving more than 50% of their value, directly or indirectly, from immovable property in a contracting state are similarly taxable in that state. All other capital gains - in particular gains on shares of standard operating or holding companies - are taxable only in the seller's state of residence.Article 13, UK-Cyprus Double Taxation Convention 2018

For a Cyprus tax resident selling UK shares, this is decisive: Cyprus does not generally tax capital gains other than on Cyprus-situate immovable property and shares of Cyprus-rich companies (Cyprus Capital Gains Tax Law N.52/1980). A treaty allocation to Cyprus on a UK share disposal therefore typically produces no tax in either jurisdiction. Gains on UK land or property-rich UK companies remain taxable in the UK regardless of Cyprus residency.

Dual residence and the treaty tiebreaker

Article 4 uses the standard OECD tiebreaker cascade for individuals: permanent home, centre of vital interests, habitual abode, nationality, mutual agreement. For companies it uses a mutual-agreement procedure (post-BEPS MLI approach) rather than a pure place-of-effective-management rule.

UK Statutory Residence Test vs Cyprus 60-day rule

The UK Statutory Residence Test (SRT), in force since 6 April 2013, is a three-stage test: automatic non-resident tests (typically <16 or <46 days), automatic resident tests (183+ days, only home in UK, or full-time work in UK), and the sufficient-ties test that combines day-count with family, accommodation, work, 90-day and country ties.

Cyprus offers two routes to tax residency. The 183-day rule (Article 2, Income Tax Law N.118(I)/2002) applies the standard threshold. The 60-day rule, introduced in 2017, lets an individual be treated as Cyprus tax resident if, in the relevant year, they (i) spend at least 60 days in Cyprus, (ii) are not tax resident in any other state, (iii) are not present in any other state for more than 183 days, (iv) carry on business in Cyprus, are employed in Cyprus, or hold an office in a Cyprus tax-resident company, and (v) maintain a permanent residence in Cyprus (owned or rented).Article 2, Income Tax Law N.118(I)/2002, as amended (Cyprus 60-day rule, 2017)

The two regimes can be made to dovetail, but only with day-count discipline. A UK leaver targeting the Cyprus 60-day rule must keep UK days below 91 (the "90-day tie" threshold under the SRT's sufficient-ties test) and must not be tax-resident anywhere else - including not tripping any automatic UK residence test in the same year. For the full mechanic, see our detailed guide to the Cyprus 60-day tax residency rule.

Split-year treatment and timing the move

UK split-year treatment (Schedule 45, Finance Act 2013) allows a tax year to be split into a UK-resident part and a non-resident part where one of eight specified cases applies. For UK-to-Cyprus moves, Cases 1 (full-time work overseas), 3 (ceasing to have a UK home) and 8 (starting to have an overseas home only) are the most common.

Cyprus has no formal split-year regime; residency is binary in any given tax year. The asymmetry is workable: arrive with enough Cyprus days to meet the 60-day or 183-day rule, qualify for UK split-year on the departure side, and any overlap days are managed under the treaty.

UK non-dom abolition and the 4-year FIG regime

Until 5 April 2025, UK tax law allowed non-UK-domiciled individuals to be taxed in the UK on the "remittance basis" - foreign income and gains were not taxed in the UK unless remitted. From 6 April 2025 that regime is abolished. It is replaced by a residence-based 4-year Foreign Income and Gains (FIG) regime under which an individual who becomes UK tax resident after at least ten consecutive tax years of non-UK residence can elect, for the first four UK tax years of residence, not to pay UK tax on qualifying foreign income and gains - whether or not those amounts are remitted to the UK.UK Finance Act 2025, abolition of remittance basis and introduction of the 4-year FIG regime, effective 6 April 2025

Three practical consequences for UK leavers: (i) the "coming home as a non-dom" option is gone - only the 4-year FIG window remains, available after a 10-year absence; (ii) IHT now turns on long-term UK residence (broadly 10 of the last 20 years), not domicile, lengthening the IHT tail; (iii) Cyprus non-dom status (a 17-year SDC exemption on dividends and most interest) becomes the natural successor for many former UK non-doms. See our Cyprus non-dom guide and the relocation playbook in our UK-to-Cyprus 2026 article.

UK pensions, QROPS and the 25% Overseas Transfer Charge

Until 30 October 2024, the UK's 25% Overseas Transfer Charge (OTC) - introduced in 2017 - excluded transfers to QROPS established in the European Economic Area (EEA), provided the member was also resident in the EEA. The 30 October 2024 Budget removed the EEA exclusion with immediate effect. From that date, transfers from a UK registered pension scheme to an EEA QROPS - including a Cyprus QROPS - attract the 25% charge unless the member is tax-resident in the same country as the receiving scheme.UK Budget 30 October 2024 - Overseas Transfer Charge: removal of EEA exclusion

For someone already Cyprus-resident, a transfer to a properly authorised Cyprus QROPS may still fall within the "same-country" exclusion. For someone still UK-resident, or for transfers to a third-country EEA QROPS, the 25% charge now bites. Transitional relief applied only where the transfer was both requested before 30 October 2024 and completed before 30 April 2025. From 6 April 2025, additional regulatory and tax-information-exchange conditions also apply. The cost of getting sequencing wrong is 25% of the transfer value.

UK CGT on UK property after departure

Becoming Cyprus-resident does not release a person from UK CGT on UK land. The UK's Non-Resident CGT regime applies to disposals of UK residential and commercial property and to disposals of substantial interests in "property-rich" UK companies (broadly, more than 75% of asset value in UK land where the seller holds at least 25%). An NRCGT return must be filed with HMRC within 60 days of completion, with any tax due paid by the same deadline.

Under Article 13 of the Convention, the UK's right to tax such gains is preserved. Cyprus, in turn, does not tax foreign immovable-property gains for individuals as a matter of domestic law, so in most cases the UK NRCGT is the only tax. Where Cyprus does charge (unusually, on indirect holdings of Cyprus-rich assets), credit relief under Article 22 of the Convention applies.

Post-Brexit company-level interactions

For corporate groups, the loss of the EU directives has changed the procedural map. Where a UK subsidiary pays a dividend, interest or royalty to a Cyprus parent, the company must today claim treaty relief explicitly rather than relying on the Parent-Subsidiary or Interest & Royalties Directive. In practice this means:

• An annual Cyprus tax-residency certificate from the Cyprus Tax Department for the recipient.
• A beneficial-ownership confirmation aligned with the OECD Commentary and the Convention's own PPT.
• Substance documentation for the Cyprus recipient: board, office, decisions, books and records in Cyprus.
• Transfer-pricing documentation for any related-party interest or royalty flow, consistent with Cyprus's formal TP rules.

For groups using a Cyprus holding or IP company alongside a UK operating company, see our wider notes on the Cyprus holding company and Cyprus IP Box regimes, both of which interact with the UK side through this treaty.

Practical relocation checklist

1. Confirm UK non-residence pathway under the SRT for the year of departure, with split-year treatment identified by case number.
2. Document the Cyprus residency route (60-day or 183-day) with diary, lease, employment/office and absence-from-other-states evidence.
3. Register for Cyprus tax (TIC), social insurance and (if applicable) GHS.
4. Register Cyprus non-dom status with the Tax Department for the 17-year SDC exemption.
5. For UK pensions, take advice before any transfer request; assume the 25% OTC applies unless a specific exclusion is documented.
6. For UK property held on departure, plan around the NRCGT 60-day reporting deadline.
7. For UK companies in the group, refresh treaty-relief documentation: residency certificate, beneficial-ownership, substance, PPT analysis.
8. Keep contemporaneous records of board location and decision-making for any Cyprus company with UK directors or shareholders.
