Moving from the UK to Dubai in 2026: SRT, 4-Year FIG Regime, and What Actually Triggers UK Tax Exit

What Changed in April 2025

Two structural reforms took effect on 6 April 2025 and changed how cross-border founders are taxed in the UK:

Sources: gov.uk — 4-year FIG regime; gov.uk — Inheritance Tax for long-term UK residents. If you are LEAVING the UK for Dubai, only the IHT change matters in your direction. The FIG regime is for people arriving INTO the UK.

The Statutory Residence Test in Detail

The Statutory Residence Test was introduced by Finance Act 2013, Schedule 45, and the official HMRC guidance is RDR3. [Source: gov.uk RDR3] The SRT decides UK residency for a tax year through three layers, applied in order.

Layer 1 — The 3 Automatic Overseas Tests

If you meet ANY ONE of these, you are automatically NOT UK resident for that tax year:

1. Previously UK resident, fewer than 16 days in UK. You were UK resident in any of the previous 3 tax years and you spend fewer than 16 days in the UK in this tax year.
2. Never previously UK resident, fewer than 46 days in UK. You were not UK resident in any of the previous 3 tax years and you spend fewer than 46 days in the UK in this tax year.
3. Full-time work overseas. You work full-time overseas with fewer than 91 UK days and fewer than 31 days on which you work for more than 3 hours in the UK.

Layer 2 — The 3 Automatic UK Tests

If none of Layer 1 applies AND you meet ANY ONE of these, you ARE automatically UK resident:

1. 183-day test. You spend 183 days or more in the UK in the tax year.
2. UK home test. You have a UK home for at least 91 consecutive days, you are present in that home for at least 30 days during the tax year, and either you have no overseas home OR you spend fewer than 30 days at any overseas home.
3. Full-time UK work test. You work full-time in the UK for any 365-day period, with more than 75% of the days you work for more than 3 hours being UK days.

Layer 3 — The Sufficient Ties Test

If neither Layer 1 nor Layer 2 settles it, count your sufficient ties to the UK. There are five:

• Family tie — your spouse, civil partner, or minor child is UK resident
• Accommodation tie — you have UK accommodation available to you for a continuous period of 91+ days, and you spend at least one night there
• Work tie — you do at least 40 days of work in the UK (3+ hours a day)
• 90-day tie — you spent more than 90 days in the UK in either of the previous 2 tax years
• Country tie — you are present at midnight in the UK in more days than in any other single country (only applies to leavers — see below)

Arrivers (no UK residence in any of the previous 3 tax years)

Leavers (UK resident in any of the previous 3 tax years)

The Day-Counting Rule

A "UK day" is a day on which you are present in the UK at midnight. Two narrow exceptions: (1) a transit day where you arrive in the UK as a passenger and leave the next day, doing nothing in the UK except activities substantially related to your journey; and (2) exceptional circumstances such as a national emergency that prevents you from leaving, capped at 60 days per tax year. Both exceptions are narrow and HMRC interprets them strictly. Plan day counts assuming the strict midnight rule applies.

Split-Year Treatment

In the year you leave or arrive, your tax year can be "split" between a UK part and an overseas part — but only if you fall into one of 8 specific Cases in the legislation. The most relevant for someone moving to Dubai: Case 1 (starting full-time work overseas), Case 2 (partner of someone starting full-time work overseas), Case 3 (ceasing to have a home in the UK). Split-year treatment is not automatic. If you do not satisfy a specific Case, your tax year is either entirely UK-resident or entirely non-resident based on the SRT result.

The Temporary Non-Residence Rule

If you become UK-resident again within 5 tax years of leaving, certain types of income and gains that you received during the non-resident period can be retroactively taxed in the year of return. This particularly catches: capital gains on assets you owned before leaving, pension lump sums, distributions from close UK companies, and loans repaid by close UK companies. If you genuinely intend to live abroad long-term, this rule is not a problem. If you might return to the UK, plan disposals carefully.

The 4-Year FIG Regime — What Replaced Non-Dom

The Foreign Income and Gains (FIG) regime took effect 6 April 2025 and replaced the remittance basis previously available to non-UK domiciled individuals. [Source: HMRC Internal Manual RFIG41000]

Who Qualifies

You qualify as a "qualifying new resident" if you become UK tax-resident after at least 10 consecutive tax years of non-UK residence. Once eligible, the relief covers your first 4 tax years of UK residence.

Transitional Provisions

You may already be a qualifying new resident if you arrived in the UK in the 2022-23 tax year or later and the prior 10-year non-residence test is met. The 4-year window then started counting from the year you became UK-resident, not from 2025.

What Is Covered

• Profits of a trade carried on wholly outside the UK
• Profits of an overseas property business
• Dividends from non-UK resident companies
• Interest, e.g. on a foreign bank account
• Foreign capital gains

What Is NOT Covered

• Foreign employment earnings — these are addressed by the separate Overseas Workday Relief (OWR) regime, not FIG
• UK source income (always taxable)
• UK situs assets

Cost of Claiming

When you claim FIG, you lose:

• The Income Tax personal allowance
• The Capital Gains Tax annual exempt amount
• Marriage Allowance, Married Couples Allowance, Blind Person's Allowance

Foreign income relieved under FIG still counts toward your "adjusted net income" for benefit calculations (e.g. Child Benefit High Income tax charge, personal allowance taper). [Source: gov.uk — 4-year FIG regime guidance]

Key insight for founders leaving the UK: The FIG regime is a tool for someone going INTO the UK, not OUT of it. If your direction of travel is UK → Dubai, you do not claim FIG — you simply use the SRT to become and remain non-UK-resident. The regime is mentioned here because (a) it changes the strategic calculus if you might return to the UK in future, and (b) it is the most-confused element of the 2025 reform.

The New Inheritance Tax Rules — Long-Term Resident Test

Until 5 April 2025, UK Inheritance Tax (IHT) was based on domicile, with a deemed-domicile rule after 15 of 20 years. From 6 April 2025, that was replaced by a residence-based test. [Source: gov.uk — IHT for long-term UK residents]

Definition of Long-Term UK Resident

You are a "long-term UK resident" for IHT purposes if you have been UK tax-resident for at least 10 of the previous 20 tax years. A long-term UK resident is within UK IHT on worldwide assets (not just UK-situs assets). When you cease to be a long-term UK resident, your IHT exposure narrows back to UK-situs assets only — but only after the "tail" period.

The Tail Period After Departure

Transitional Rule for Pre-2025 Deemed-Domiciled Individuals

If you were deemed-domiciled in the UK on 30 October 2024, you become a long-term UK resident on 6 April 2025 and you only shed that status after 3 years of non-UK residence, regardless of your prior UK residence length.

Trust Implications

Trusts settled by a settlor while they were UK-domiciled (pre-2025) or long-term UK-resident (post-2025) carry IHT exposure on overseas assets. Trusts settled by non-domiciled individuals before 30 October 2024, where assets remained overseas, retain their pre-reform "excluded property" protection. [Source: HMRC Internal Manual IHTM47020]

UAE Side: Becoming a UAE Tax Resident

UAE tax residency is governed by Cabinet Decision No. 85 of 2022 which entered into force on 1 March 2023. [Source: tax.gov.ae — Cabinet Decision 85 of 2022 PDF]

Two Paths to UAE Tax Residency for an Individual

Path A — The 183-Day Rule. You are physically present in the UAE for 183 days or more in any consecutive 12-month period. No additional conditions required.

Path B — The 90-Day Rule. You are physically present in the UAE for 90 days or more (but fewer than 183) in any consecutive 12-month period AND:

• You are a UAE national OR you hold a valid UAE residence permit OR you are a national of a Gulf Cooperation Council (GCC) member state, AND
• You have either a permanent place of residence in the UAE OR you carry on employment or business in the UAE

Tax Residency Certificate (TRC)

Once you meet either path, you can apply to the Federal Tax Authority (FTA) for a Tax Residency Certificate through the EmaraTax portal. [Source: mof.gov.ae announcement] The TRC is the official document presented to foreign tax authorities (including HMRC) to invoke double taxation treaties.

Practical Sequence for a UK-to-Dubai Founder

1. Obtain a UAE residence permit (typically via a free-zone investor visa — see our Free Zone Comparison guide)
2. Establish a permanent home in the UAE (lease or purchase)
3. Spend 90+ days physically present in any 12-month window — track entries and exits via the ICP or GDRFA app
4. Apply for the TRC through EmaraTax once eligible. The TRC takes a few weeks to issue and is typically valid for 12 months from issue.

Dual Residence: The UK-UAE Treaty Tie-Breaker

If in the same year you meet both UK SRT and UAE Cabinet Decision 85 residency criteria, you are dual-resident under domestic law. The 2016 UK-UAE Double Taxation Convention (signed 12 April 2016, entered into force 25 December 2016, modified by the Multilateral Instrument from 2020) provides a tie-breaker in Article 4 that decides which country wins for treaty purposes. [Source: gov.uk — UAE tax treaties] [Synthesised treaty PDF]

Tie-Breaker Hierarchy (applied in order)

1. Permanent home. Resident in the country where you have a permanent home available. If both, go to step 2.
2. Centre of vital interests. The country where your personal and economic relations are closer (family, business, social ties). If unclear, go to step 3.
3. Habitual abode. The country where you spend more time over a sustained period. If both equal, go to step 4.
4. Nationality. The country of which you are a national. If both or neither, go to step 5.
5. Mutual Agreement Procedure (MAP). HMRC and the UAE FTA settle by negotiation.

This OECD Model Convention pattern is standard and the UK-UAE treaty follows it. The practical implication: in your first year in Dubai, if you maintain a UK home and your spouse and minor children remain in the UK, UK is likely your "centre of vital interests" and the treaty assigns you UK residency for that year — even if you spent most of it in Dubai. Plan accordingly.

The Practical Path: Year-By-Year Planning

Pre-Departure (Final UK Tax Year)

• Review SRT day count for the current year — you may already be approaching a residence threshold
• Decide whether split-year treatment can apply (Cases 1, 2, or 3 most likely)
• File Form P85 when you leave the UK (or in your Self Assessment) to notify HMRC
• Settle outstanding UK tax obligations (Self Assessment, PAYE underpayment, capital gains)
• Document the date you ceased to be UK resident (boarding pass, lease termination, container shipping receipt)

First UAE Tax Year (year 1 abroad)

• Hit one of the SRT automatic overseas tests: spend fewer than 16 days in the UK if previously resident, OR work full-time overseas with fewer than 91 UK days
• Establish UAE residency: visa + Emirates ID + permanent home + bank account
• Track every UK day meticulously (most founders use a dedicated app)
• Be careful of the temporary non-residence rule if you might return within 5 years

Years 2 to 5 (Consolidating Non-Residence)

• Maintain SRT non-residence each year
• Apply for UAE Tax Residency Certificate to invoke the DTC where needed
• Track the IHT tail: you remain within UK worldwide IHT for 3-10 years depending on prior UK residence length
• If returning to the UK temporarily, keep visits below the SRT thresholds for your situation

Year 6+ (Cleanly Non-Resident)

• For most former UK residents, the IHT tail expires
• For someone resident 10-13 years before leaving, the long-term UK resident IHT status ends after 3 years of non-residence
• Beyond the tail, only UK-situs assets remain within UK IHT

Common Mistakes Founders Make

When You Need a UK Chartered Tax Adviser

UK tax residence and IHT are complex and personal. The rules above are the published HMRC guidance as of 2026 and the references below link to the canonical official sources. They are NOT a substitute for advice from a qualified UK Chartered Tax Adviser (CTA) or an international tax specialist. Common situations that need bespoke advice:

• You hold UK property or a UK pension
• You are a partner in a UK business
• You hold UK trust beneficial interests
• You are a US person (US citizenship overrides residence for US tax purposes)
• You have minor children remaining in UK schools
• You earn UK income that may continue after departure (royalties, rental, consulting)
• You are considering returning to the UK within 5 years

For high-stakes decisions (significant capital gains realisation, trust restructuring, large gifts), the cost of a CTA consultation is a fraction of the tax exposure if you get the timing wrong.

Frequently Asked Questions

How many days can I spend in the UK without being UK tax-resident?

It depends on your prior status and ties. As a full-time UK leaver in your first year of non-residence, you can usually spend up to 15 days in the UK without triggering residence at all. Up to 90 days is possible if you have no more than one or two of the five UK ties. As an established non-resident with no UK ties, you can spend up to 182 days. The exact threshold is determined by the SRT day-count tables for your situation under HMRC RDR3 guidance.

Does spending less than 183 days in the UK make me automatically non-resident?

No. The 183-day test only operates as an automatic UK test (more than 183 days = automatically resident). Below 183 days, residence is decided by the automatic overseas tests and the sufficient ties test. You can be UK-resident with as few as 16 days if you have all four UK ties.

Can I claim the FIG regime if I am moving FROM the UK to Dubai?

No. The 4-year Foreign Income and Gains regime is for people moving INTO the UK after 10+ years of non-UK residence. If you are leaving the UK for Dubai, the FIG regime is not relevant. Your tool is the SRT — establish non-residence and stay non-resident.

How long after leaving the UK am I out of UK Inheritance Tax?

If you were UK-resident for 10 to 13 years of the last 20 before leaving: 3 years tail. 14 years: 4 years. Each additional prior UK year adds one tail year, capped at 10 years for someone resident every year of the last 20.

Do I need a UAE Tax Residency Certificate to be non-UK-resident?

No. UK non-residence is determined by the SRT alone. A UAE Tax Residency Certificate is needed to invoke the UK-UAE double taxation treaty (e.g. when claiming reduced withholding on UK source income, or proving residence to a third country). For pure SRT non-residence, the TRC is not required.

What happens to my UK pension and ISAs after I leave?

Your existing UK pension and ISAs continue to exist after you leave. UK pension income remains UK-source and may be taxable in the UK subject to the UK-UAE treaty rules. ISAs lose their tax-free status from the UAE perspective — UK exempts them but the UAE has no personal income tax anyway.

Can I keep visiting the UK frequently after I leave?

Yes, as long as you stay below your SRT day threshold for your situation. Track every visit. Many founders use a dedicated day-tracking app and treat the UK day count as a hard ceiling, scheduling alternative travel when approaching the limit.
