UK non-doms moving to Singapore post-2025 reform: Common mistakes

UK non-doms relocating to Singapore after the 6 April 2025 abolition of the remittance basis often misapply the UK’s new four-year Foreign Income and Gains (FIG) regime to their Singapore tax position, or assume Singapore still recognises “non-domiciled” status, which it does not. This guide sets out the most common errors and how to avoid them.

What changed in the UK, and why it matters in Singapore

The remittance basis of taxation, available to UK resident non-domiciled individuals for over two centuries, ended on 6 April 2025. It has been replaced by the FIG regime: an individual who has been non-UK resident for at least 10 consecutive tax years can, on becoming UK resident again, claim relief on foreign income and gains for a maximum of four tax years. After the four years lapse, the individual is taxed on worldwide income and gains in the same way as any other UK resident, regardless of domicile. Domicile as a concept still exists for UK inheritance tax purposes, and the UK also introduced transitional rules for pre-2025 offshore trusts, but the FIG regime no longer drives income tax and capital gains tax treatment the way “non-dom” status used to.

The common mistake for someone leaving the UK for Singapore is treating “non-dom” as a portable label that follows them abroad. It is not. Singapore’s Income Tax Act 1947 taxes individuals on a residence basis, not a domicile basis, and has never had a UK-style remittance concept. Arriving in Singapore does not extend, replace or interact with the FIG regime; it simply starts a separate Singapore tax residency assessment from scratch, governed entirely by Singapore statute and IRAS administrative practice.

This distinction matters most for individuals who spent time in the UK on the old remittance basis, became deemed domiciled after 15 years of UK residence under the pre-2025 rules, and are now relocating to Singapore partly to reset their position. The reset happens on the UK side through the statutory residence test and the FIG regime’s 10-year qualifying non-residence condition, not through anything that happens automatically upon arrival in Singapore.

Who this affects

This guide is for UK nationals and long-term UK residents, including those who have used or are considering the FIG regime, who are relocating to Singapore for employment, business ownership or retirement. It also applies to non-UK domiciled individuals who spent time in the UK under the old remittance basis and are now reassessing offshore trust structures, investment portfolios and UK property holdings given the reform. Family offices and private banks advising UK-connected clients into Singapore should treat this as a standing checklist item in onboarding.

Common mistake 1: assuming Singapore tax residency is automatic

Under the Income Tax Act 1947, an individual is generally treated as a Singapore tax resident for a Year of Assessment if they were physically present or exercised employment in Singapore for 183 days or more in the preceding calendar year, with an administrative concession available for individuals expected to stay for a continuous period straddling two calendar years. Arriving mid-year on an Employment Pass does not automatically confer resident status for that first partial year; a common rejection reason in filings is claiming resident reliefs, such as the earned income relief or resident tax rate bands, before the 183-day threshold is actually met or before the relevant IRAS concession genuinely applies to the individual’s travel pattern. IRAS routinely asks for entry and exit stamps, travel logs or immigration records where residency is contested, so relocating individuals should keep these from day one rather than reconstructing them at filing time.

Common mistake 2: double-counting UK FIG relief and Singapore’s foreign-sourced income treatment

Singapore does not tax most foreign-sourced income received by individuals, as opposed to income received through a partnership carrying on a trade in Singapore, so income sheltered under the UK’s FIG regime is frequently also outside the Singapore tax net entirely, but for entirely unrelated reasons. Filing preparers sometimes assume this overlap means no disclosure is needed anywhere. In fact, UK FIG relief has its own annual claim mechanics and record-keeping requirements on the UK side, and Singapore’s foreign-sourced income treatment depends on source, remittance and, in limited cases, the specified foreign income exemption rules that must still be evidenced if IRAS queries a filing. Treat the two regimes as entirely separate analyses conducted in parallel, not a single combined exemption that can be claimed once and forgotten.

Common mistake 3: ignoring the UK statutory residence test on exit

Moving to Singapore does not automatically end UK tax residence. The UK statutory residence test looks at day counts in the UK, connecting ties such as family, accommodation and work, and prior-year UK residence history across a rolling multi-year window. Individuals who continue frequent UK travel for work, retain a UK home available for their use, or keep a UK-resident spouse or minor children in UK education often remain UK tax resident for one or more tax years after the physical move to Singapore, which in turn affects whether the FIG regime’s four-year clock has even started to run. A frequent and costly error is an individual telling a Singapore employer, immigration adviser or private bank “I am now Singapore tax resident and no longer a UK taxpayer” while UK ties mean the statutory residence test still finds them UK resident, and the FIG regime clock has not properly commenced.

Common mistake 4: mismanaging CPF and retirement planning assumptions

UK non-doms who become Singapore Permanent Residents or citizens acquire Central Provident Fund obligations that have no UK equivalent and are not addressed by any UK non-dom or FIG concept. A frequent gap in relocation planning is failing to model employer and employee CPF contribution obligations at the point PR status is granted, or conversely assuming CPF contributions substitute for continuing UK pension planning, which they do not for a UK national who has not yet naturalised and who may still hold UK-registered pensions subject to their own separate cross-border tax treatment under the UK-Singapore double tax agreement.

Common mistake 5: overlooking UK inheritance tax exposure after the move

Because UK inheritance tax retained a domicile-linked test even after the income tax and capital gains tax reform, individuals sometimes assume that becoming Singapore tax resident, or even applying for Singapore citizenship, automatically removes UK inheritance tax exposure on worldwide assets. In practice, UK inheritance tax uses its own long-term residence test with lookback periods that can keep a departing individual within the UK inheritance tax net for several years after relocation, independent of Singapore tax residency status entirely. This should be reviewed as a distinct workstream from the income tax planning described above, ideally with a UK private client adviser working alongside Singapore counsel.

Numerical specifics: costs, thresholds and deadlines

UK FIG regime: up to 4 tax years of relief, conditional on 10 consecutive years of prior non-UK residence.
Singapore tax residency: 183 days or more of physical presence or employment in the preceding calendar year, subject to administrative concession for qualifying multi-year stays.
Singapore Form B filing deadline: 15 April (paper) or 18 April (e-filing) each year.
Typical cross-border UK-Singapore repositioning advisory fee: S$3,000 to S$8,000, depending on trust, offshore company or UK property complexity.
Typical engagement timeline: 4 to 8 weeks from first consultation to a written position paper covering both jurisdictions.
IRAS assessment turnaround: typically 8 to 12 weeks after a complete Form B filing.

Step-by-step: getting the transition right

Confirm UK residence status for the year of departure using the statutory residence test, not assumption or informal advice from a relocation agent.
Establish the actual start date of the UK FIG regime’s four-year window, if claimed, based on the 10-year non-UK-residence qualifying condition being genuinely satisfied.
Assess Singapore tax residency separately under the 183-day test and any applicable IRAS administrative concession for the year of arrival.
Map foreign-sourced income and gains against Singapore’s exemption rules, keeping evidence of source and remittance entirely separate from UK FIG documentation.
Register for CPF if becoming a Permanent Resident, and review continuing UK pension contributions and UK-registered pension cross-border treatment separately.
Review UK inheritance tax exposure under the long-term residence test independently of the income tax analysis.
File Singapore Form B by 15 April, or 18 April for e-filing, for the relevant Year of Assessment, and keep parallel UK self-assessment obligations current for any UK-source income or FIG-regime claims.

Why IRAS and immigration checks flag these cases

In practice, a Singapore filing or pass renewal is queried rather than accepted outright when the paperwork tells two inconsistent stories at once. A common pattern is an individual whose employment pass application states a Singapore start date, whose bank onboarding forms state a different effective residence date for a UK-linked account, and whose UK self-assessment return for the same period is silent on the move altogether. IRAS and, separately, private banks running source-of-wealth checks for MAS-regulated entities, will ask for the underlying travel record, the UK exit position and the FIG regime claim (if any) to be reconciled before proceeding. Individuals who prepare this reconciliation before it is asked for, rather than after a query is raised, avoid weeks of delay in both the tax filing and any related banking or immigration process.

A second recurring rejection reason is claiming Singapore resident tax reliefs, such as the earned income relief, in a Year of Assessment where the 183-day test was not actually met and no administrative concession applied, typically because the individual under-counted days spent outside Singapore on UK or European business trips during the qualifying period. Keeping a simple day-count log from the date of arrival resolves this in almost every case.

FAQs

Does the UK’s FIG regime give me any relief in Singapore?
No. The FIG regime is a UK domestic tax relief with no bearing on how IRAS assesses Singapore tax residency or Singapore-sourced income. The two systems are assessed entirely independently.

Am I still a UK non-dom if I move to Singapore?
The non-dom income tax and capital gains tax treatment no longer exists in UK law as of 6 April 2025. Domicile remains relevant to UK inheritance tax, so this should be reviewed separately from your income tax position.

How long does the FIG regime last if I later return to the UK?
Up to four UK tax years of relief on foreign income and gains, provided the 10-year non-UK-residence qualifying condition was met before the UK return.

Do I need a Singapore employment pass before I can be tax resident here?
No. Tax residency depends on days present or employment exercised in Singapore, not pass type, though most relocating professionals will hold an Employment Pass or a similar work pass throughout the qualifying period.

Should I get UK and Singapore advice from the same firm?
Coordinated advice between a UK private client adviser and Singapore counsel reduces the risk of the two regimes being treated, wrongly, as one combined exemption. Little Big Employment Agency works with a panel of corporate and employment law firms and tax advisers on both sides for exactly this reason.
