UK non-doms moving to Singapore post-2025 reform — Costs and fees breakdown
UK non-doms moving to Singapore post-2025 reform are moving from a regime that taxed unremitted foreign income lightly to a UK residence-based system, and many are choosing Singapore precisely because it does not tax most foreign income or capital gains. The cost of a well-planned move, covering tax advice on both sides, typically runs S$5,000–S$20,000, and the savings for larger estates can be far greater.

Why UK non-doms moving to Singapore post-2025 reform are recalculating
UK non-doms moving to Singapore post-2025 reform are responding to a simple change of arithmetic. Under the old remittance basis, a non-dom could keep foreign income and gains offshore and largely outside UK tax. From 6 April 2025 that shelter closed, replaced by a residence-based system with only a short window of relief for new arrivals. For someone with large foreign investment portfolios, staying UK-resident now means UK tax on worldwide income and gains, sometimes at 45% and 24% respectively.
Singapore offers a sharply different profile: residents are taxed on Singapore-sourced income and certain foreign income received here, at progressive rates capped well below UK top rates, with no general capital gains tax and no estate duty. For a mobile individual whose income is genuinely foreign-sourced, the combined effect of ceasing UK residence and becoming Singapore-resident can be transformational, provided the move is real and cleanly executed.
The reform has therefore turned a lifestyle question into a tax-driven one, and Singapore, Dubai and a handful of other centres are the usual beneficiaries.
What changed in the UK from April 2025
The United Kingdom abolished the long-standing remittance basis for non-domiciled individuals with effect from 6 April 2025, replacing it with a residence-based regime and a time-limited relief for new arrivals. Individuals who previously kept foreign income and gains outside the UK tax net by not remitting them now face UK tax on worldwide income and gains once UK-resident beyond the transitional window. For internationally mobile wealth, this materially changed the calculus of staying in the UK.
Why Singapore is attractive
Singapore taxes residents on Singapore-sourced income and on foreign income received here that does not qualify for exemption, and it does not levy a general capital gains tax or an estate duty. For an individual with substantial foreign investment income and gains, becoming Singapore tax-resident and ceasing UK residence can remove the UK worldwide charge and leave much of the foreign income and gains untaxed in Singapore, subject to the rules on remittance and source.
Who this applies to
The move suits former UK-resident non-doms with significant foreign income and gains, entrepreneurs and fund principals, and families planning multi-generational succession. It is less relevant to those whose income is UK-sourced, which remains within the UK charge regardless of residence.
Establishing Singapore residence
An individual becomes Singapore tax-resident broadly by being physically present or employed here for at least 183 days in a year, with concessions for those who qualify. Genuine relocation, a home, family presence and time in Singapore all support the position. Employment or business here usually requires an Employment Pass or, for senior talent, the ONE Pass. Our note on personal income tax for expats, resident versus non-resident, covers the residency mechanics.
Cost, timeline and the UK exit
The critical work is timing the UK departure and the Singapore arrival across UK tax years to break UK residence cleanly under the Statutory Residence Test, and reviewing UK capital gains, trust and inheritance-tax exposure that can persist after departure. Combined UK and Singapore advice typically costs S$5,000–S$20,000. The relocation itself, including immigration and setting up a home, generally spans two to four months. Foreign income remitted to Singapore should be reviewed against the foreign-sourced income rules; see our note on the foreign-sourced income exemption for individuals.
Structuring and succession
Many arrivals hold assets through trusts or investment companies. UK inheritance tax can still reach UK situs assets and, under the new regime, long-term UK residents, so structuring should be reviewed rather than assumed. On the Singapore side, families often establish holding or trust structures; see our sister guides on personal tax filing for owner-directors and succession planning across PR and citizenship.
Common mistakes and gotchas
The frequent errors are: leaving the UK without breaking residence under the Statutory Residence Test; overlooking UK inheritance tax that survives departure; remitting foreign income to Singapore without checking the source and receipt rules; and assuming Singapore residence is automatic on arrival. Both tax systems must be planned together, not sequentially.
A practical relocation timeline
A clean move usually spans two to four months and runs roughly as follows: take combined UK and Singapore tax advice and model the exit (weeks 1–4); secure the Singapore immigration route, whether Employment Pass, ONE Pass or dependant arrangements (weeks 2–8, overlapping); time the physical departure to break UK residence under the Statutory Residence Test, which often means minding day-counts across the 6 April UK year boundary; establish a Singapore home and bank accounts (weeks 6–12); and review asset structures and any remittance of foreign income into Singapore against the source and receipt rules before funds move. The recurring lesson is that the UK exit and the Singapore arrival are one project with two tax authorities, and small timing errors, a few days too many in the UK, can cost a full year of worldwide UK exposure.

FAQs
What happened to the UK non-dom regime?
The UK abolished the remittance basis from 6 April 2025, replacing it with a residence-based regime and a time-limited relief for new arrivals, so worldwide income and gains are taxed once UK-resident beyond the transition.
Why move to Singapore?
Singapore taxes residents on Singapore-sourced income and certain foreign income received here, and has no general capital gains tax or estate duty, which can remove much of the UK worldwide charge.
How do I become Singapore tax-resident?
Broadly by being present or employed in Singapore for at least 183 days in a year, supported by genuine relocation and, usually, an Employment Pass or ONE Pass.
Does UK tax stop immediately on leaving?
No. UK residence must be broken under the Statutory Residence Test, and UK inheritance tax and certain gains exposure can persist after departure.
