Non-dom in UK today

 


The traditional UK non-domicile (non-dom) tax regime was officially abolished on 6 April 2025. In 2027, cross-border individuals living in the UK operate entirely under the new residence-based tax framework.

How you are taxed in 2027 depends on whether you are a new arrival, a continuing resident, or managing pre-2025 offshore funds.

Regime ElementPre-April 2025 RulesRules in Effect for 2027
Core StatusDomicile-basedStrictly residence-based (Statutory Residence Test)
New Arrivals ReliefRemittance basis (indefinite, subject to annual charges)4-Year Foreign Income & Gains (FIG) Regime
Tax on Worldwide IncomeOnly on remittance to the UKWorldwide arising basis once outside the 4-year FIG window
Historic Offshore FundsTaxed up to 45% upon transfer to the UKTemporary Repatriation Facility (TRF)
Inheritance Tax (IHT)Based on domicile & deemed domicileWorldwide estate exposure after 10 years of UK residence

1. The 4-Year Foreign Income & Gains (FIG) Regime

  • Eligibility: Applies to individuals who become UK tax resident after at least 10 consecutive tax years of non-UK residence.

  • The Exemption: For the first 4 tax years of UK tax residence, qualifying foreign income and foreign capital gains are 100% exempt from UK tax.

  • Free Remittance: Unlike the old rules, you can bring this money into the UK without triggering any tax charges.

  • Trade-off: Claiming the FIG regime forfeits your UK Income Tax personal allowance and the annual CGT exemption for that year.

2. Long-Term Residents (Arising Basis)

  • If you have lived in the UK for more than 4 tax years (including those who transitioned through the 2025 reform), you are taxed on the worldwide arising basis.

  • All global income and capital gains arising in 2027 must be reported on your UK Self Assessment tax return and are taxed at ordinary UK income tax (up to 45%) and CGT rates, regardless of whether funds enter the UK.

3. Temporary Repatriation Facility (TRF) — The 2027 Rate Hike

  • The TRF applies to former non-doms holding unremitted foreign income and capital gains accrued before 6 April 2025.

  • Rate for the 2026/27 tax year (up to 5 April 2027): 12% flat charge.

  • Rate for the 2027/28 tax year (starts 6 April 2027): 15% flat charge.

  • No physical transfer required: You can designate qualifying funds on your tax return, pay the flat 15% charge (or 12% if designated for 2026/27), and leave the funds offshore indefinitely to be brought to the UK tax-free later.

  • Note: The TRF closes permanently on 5 April 2028, after which historic funds face ordinary rates up to 45% if remitted.

4. Inheritance Tax (IHT)

  • UK IHT is decoupled from domicile. You are considered a long-term resident for IHT once you have been UK resident in at least 10 out of the last 20 tax years.

  • Once you meet that 10-year threshold, your worldwide estate is subject to 40% UK IHT.

  • Leaving the UK triggers a "tail provision" where you remain within the scope of worldwide IHT for between 3 to 10 years depending on how long you resided in the UK.

To assess your specific tax exposure, consider:

  1. Your arrival date: Did you move to the UK recently (potentially inside the 4-year window), or are you a long-term resident?

  2. Offshore balances: Do you hold untaxed pre-April 2025 funds that could be designated under the TRF before the window closes in 2028?

  3. UK tenure: How many of the past 20 years have you spent in the UK for Inheritance Tax purposes?

How UK Farming Went from ‘Dig for Victory’ to High-Tech Agronomy

  Agriculture has shaped around 70% of the UK’s landmass, transitioning from subsistence strip farming to a highly mechanized, tech-driven industry navigating environmental and post-Brexit policy shifts. The Historical Evolution Neolithic to Medieval Open Fields (4500 BC–1500s): Farming arrived in Britain during the Neolithic era, gradually replacing hunter-gatherer lifestyles. Medieval agriculture relied on manorial open fields divided into narrow strips, where peasant farmers pooled oxen to plough common land under feudal lords. The British Agricultural Revolution (17th–19th Century): Enclosure Acts: Fenced in common land, consolidating smallholdings into larger private farms and driving displaced farmhands toward industrial cities. Agronomic breakthroughs: Jethro Tull’s seed drill (1701), Robert Bakewell’s selective livestock breeding, and Charles Townshend’s Norfolk four-course rotation (wheat, turnips, barley, clover) eliminated fallow years, vastly boosting yields and ...
