Bank Account Strategy for UK Non-Domiciliary Clients Under the FIG Regime

The April 2025 replacement of the UK's remittance basis with the Foreign Income and Gains (FIG) regime was the most significant change to UK non-domiciliary taxation in a generation. While the FIG regime substantially simplifies the position for newly arrived individuals — offering a clean four-year exemption without the annual remittance basis charge — it also requires careful banking architecture to actually deliver that exemption in practice.

Getting the bank accounts right before you arrive in the UK, or very shortly after, is one of the most important practical steps a newly UK-resident internationally mobile individual can take.

Understanding the FIG regime

The FIG regime applies to individuals who become UK tax resident having not been UK resident in any of the previous ten tax years. During the first four years of UK residence, offshore income and gains are completely exempt from UK income tax and capital gains tax. There is no election required, no charge to make, and no requirement to keep the income offshore — you simply do not pay UK tax on it.

This is a significant improvement on the old remittance basis, which required an annual charge of up to £60,000 simply to access the offshore exemption, and which required you to keep the offshore income offshore (or face remittance tax if you brought it to the UK).

After the four-year FIG window closes, the individual moves into the standard UK worldwide taxation regime. From that point, all income and gains from wherever they arise are subject to UK tax.

Why the banking structure still matters

Even with the FIG regime's simpler rules, the banking structure matters for two reasons:

First, the clean capital rules still apply after the FIG window closes. Pre-arrival capital (capital that existed before you first became UK-resident) can always be remitted to the UK free of tax, whenever you bring it. Post-arrival income and gains cannot be remitted without a tax charge (once the FIG window has closed). Keeping pre-arrival capital in a demonstrably clean account — separate from later income and gains — preserves this flexibility indefinitely.

Second, the mixed fund ordering rules are merciless. Once an account contains a mixture of clean capital and post-arrival income or gains, HMRC treats remittances from that account as coming from income first, gains second, and capital last. If you allow pre-arrival funds to mix with post-arrival income in a single account, you may inadvertently eliminate the clean capital benefit that would otherwise be available to you when you leave the UK or in later years.

The three-account structure

For most newly arrived non-domiciliary individuals, a minimum three-account structure provides the necessary separation:

Account 1: UK current account

Hold this at a UK bank. It receives UK-source income (UK employment income, UK bank interest, UK rental income if any) and is used to pay UK expenses. There is no tax complexity here — UK-source income is taxable in the UK regardless of non-dom status, so this account requires no special management.

For HNW individuals, this may be a UK private bank account (Coutts, Barclays Private Bank, HSBC Private Banking) where the relationship manager understands non-dom structure.

Account 2: Offshore clean capital account

This account is established before UK arrival and funded only with pre-arrival capital. After UK arrival, it receives nothing — no investment returns, no rental income, no dividends, nothing. It simply holds the pre-arrival capital intact.

If you need to transfer money to the UK for living expenses or investment, this account is the source. Remittances from a demonstrably clean capital account do not trigger UK tax — now or in the future. Even after the FIG window closes and you are on worldwide taxation, the ability to remit clean capital remains.

The account should be at an offshore bank — Isle of Man, Jersey, Guernsey, or Cayman Islands. All of these jurisdictions are experienced at non-dom client banking and have stable banking infrastructure.

Account 3: Offshore income and gains account

This account receives all offshore income during the FIG window: dividends from offshore investments, rental income from overseas properties, business distributions from overseas companies, interest from offshore deposits. During the four-year FIG window, this income is entirely UK-tax-free regardless of what you do with it — but it is prudent to keep it offshore to avoid any ambiguity.

After the FIG window closes, this account may contain significant accumulated income that cannot be remitted to the UK without a UK tax charge. At that point, you have choices: leave the funds offshore for deployment in non-UK investments; remit in a low-income year to minimise the marginal rate; or structure a phased remittance over multiple years. Having kept the funds clearly identified and separate means you can make these decisions with clarity.

Choosing the offshore jurisdiction and institution

Isle of Man: a well-regarded British Crown Dependency with its own Financial Services Authority (IOMFSA). Deposits are protected up to £50,000 under the IoM Depositors' Compensation Scheme (different from FSCS). Major banks include Lloyds Bank International, Barclays Wealth (international arm), and several trust companies with banking capabilities. Strong expertise in non-dom and international private client structures.

Jersey and Guernsey: also British Crown Dependencies with mature financial services sectors. Jersey Financial Services Commission and Guernsey Financial Services Commission regulate their respective banking sectors. Coutts International, RBS International, Standard Bank International, HSBC Expat, and Barclays International all have Channel Islands operations. These jurisdictions are particularly well-suited to clients with investment portfolios, trusts, and multi-generational wealth structures.

Cayman Islands: useful for clients with US connections or complex multi-jurisdiction structures. No deposit protection scheme equivalent to the UK/CI model, but the overall regulatory framework under the Cayman Islands Monetary Authority (CIMA) is robust.

The choice between these jurisdictions is often driven by where your wealth manager or investment manager is based, since the banking and investment relationship often sit together.

FATCA, CRS, and transparency

Non-domiciliary individuals resident in the UK should be aware that all of the offshore jurisdictions named above participate in the OECD Common Reporting Standard (CRS). This means that your offshore account balance and income are automatically reported to HMRC annually.

This is not a problem if you are filing self-assessment correctly — declaring offshore income under the FIG regime (which gives you the exemption) and reporting clean capital accurately. It does mean that HMRC has visibility of offshore accounts and can cross-reference against self-assessment returns. Compliance is essential.

FATCA applies to US persons regardless of where they live. If you are a US citizen or green card holder resident in the UK, your offshore accounts are reported to the IRS via FATCA. US non-doms face a complex dual-reporting obligation and should take specific US/UK dual-tax advice.

The anti-avoidance trap

Having offshore bank accounts does not of itself constitute legitimate UK tax planning. The benefit arises from the source of the funds (offshore income within the FIG window) and the maintenance of clean capital separation. Simply moving money to an offshore account after you are already UK-resident does not create FIG regime benefits — the income or gains must have arisen outside the UK in the relevant period.

The offshore bank account is a tool for protecting an existing legitimate benefit (the FIG exemption and the clean capital position), not a mechanism for creating one.

Setting up before arrival

The ideal time to establish the offshore banking structure is before you arrive in the UK. This allows you to:

• Identify all pre-arrival assets clearly
• Open the clean capital account in the offshore jurisdiction and fund it with pre-arrival capital
• Identify which assets generate income and gains and route those into the income account
• Arrive in the UK with a clear baseline

If you have already arrived in the UK without having set up this structure, it is still possible to establish it, but you will need to carefully document and segregate funds based on their pre- or post-arrival status. This is more work, but is achievable with the help of a qualified UK non-dom tax adviser.

How Global Investments can help
