The treaty does the heavy lifting
The rule in Article 17 of the 2018 UK-Cyprus Double Taxation Convention is unusually clean: pensions paid to a Cyprus resident are taxable only in Cyprus, not merely relieved by credit. That covers SIPP drawdown, workplace pensions and annuities, and because the treaty has no separate social security article the State Pension follows the same rule in practice. The exception is a government service pension, which stays taxable only in the UK unless you are both resident in Cyprus and a Cypriot national. None of this applies until you have genuinely broken UK residence under the Statutory Residence Test, usually with split-year treatment in the year you leave, so the UK exit is step one.
The Cyprus side: 5% flat rate or the normal bands
Cyprus lets foreign pensioners choose each year between a flat 5% rate on foreign pension income above a 5,000 euro threshold (raised from 3,420 euros on 1 January 2026) and the normal income tax bands, which are 0% up to 22,000 euros and rise in steps to 35% above 72,000 euros. Smaller pensions often do better under the bands; larger pensions almost always do better at 5%, and the election is annual so you genuinely pick the cheaper answer each year. Retirees living partly off investments do even better, because the Cyprus non-dom regime removes Special Defence Contribution on dividends and interest for up to 17 years.
What stays in the UK net
Three things need managing. First, UK PAYE does not stop by itself: you claim an NT code through form DT-Individual with a Cypriot residency certificate, expect emergency tax on the first withdrawal and a wait of roughly 12 to 16 weeks. Second, any UK property you keep stays UK-taxed, with rent under the Non-Resident Landlord Scheme and sales reportable within 60 days under non-resident CGT. Third, from 6 April 2027 unused UK pension funds fall into the UK inheritance tax estate even for non-residents, which matters for large pots. Horizon handles the whole UK side of a Cyprus retirement, from the SRT exit to the NT code and ongoing returns, on fixed fees agreed upfront (non-resident returns from £550), and a free clarity call at /book is the easiest place to start.
