For over two centuries, the non-domicile (non-dom) tax regime has been a cornerstone of the UK’s appeal to high-net-worth individuals (HNWIs). However, following successive government announcements and the confirmed legislative overhaul set for April 2025, we are witnessing the end of the non-dom status as we know it. The remittance basis of taxation is being abolished, replaced by a stricter, residence-based system known as the Foreign Income and Gains (FIG) regime.

For wealthy residents and international families, the landscape has shifted dramatically. The question is no longer if the rules will change, but how to adapt your wealth preservation strategy to survive the transition. This guide explores the new fiscal reality, the implications for Inheritance Tax (IHT), and actionable strategies for those affected—from restructuring offshore assets to potential relocation.

The Death of the Remittance Basis: What Has Changed?

Historically, non-doms could opt to be taxed on the "remittance basis," meaning they only paid UK tax on foreign income and gains if that money was brought (remitted) into the UK. This allowed wealth to compound tax-free offshore.

From April 6, 2025, the concept of domicile as a relevant connecting factor for tax purposes is being scrapped. It is being replaced by a statutory residence-based test. The key changes include:

• Abolition of Domicile: Your tax status will no longer depend on where your father was born or where you intend to retire. It will depend strictly on how long you have lived in the UK.
• The 4-Year FIG Regime: New arrivals to the UK (who have not been UK resident in the previous 10 tax years) will enjoy a 4-year exemption window. During this time, they can bring foreign income and gains into the UK tax-free.
• Worldwide Taxation: After the 4-year period, residents will be taxed on their worldwide income and gains, exactly like any other UK taxpayer, regardless of whether the money is remitted or kept offshore.

The Transitional Arrangements

Recognizing the shock to the system, the government has proposed transitional measures. Understanding these is critical for short-term planning:

1. Temporary Repatriation Facility (TRF): For a limited time (likely two tax years following the change), former remittance basis users may be able to remit pre-existing foreign income and gains at a reduced tax rate (proposed at 12% rather than the standard top rates of 45%). This presents a significant opportunity for repatriating offshore profits to the UK efficiently before the window closes.
2. Rebasing of Capital Assets: There may be provisions allowing individuals to rebase the value of their foreign assets to a 2019 or later date, reducing the Capital Gains Tax (CGT) exposure upon future disposal.

Inheritance Tax (IHT): The Sting in the Tail

While the income tax changes are significant, the reforms to Inheritance Tax are arguably more aggressive. Previously, non-doms could protect non-UK assets from the 40% UK IHT indefinitely using Excluded Property Trusts (EPTs).

Under the new proposals:

• Residence-Based IHT: Liability for IHT on worldwide assets will kick in once a person has been UK resident for 10 years.
• The 10-Year "Tail": If a person leaves the UK after being resident for 10+ years, they remain liable for UK IHT on their worldwide assets for a further 10 years after departure. This makes the UK a "sticky" jurisdiction for tax purposes.
• Trust Protections Removed: Most critically, the protection previously afforded to Excluded Property Trusts settled by non-doms before they became deemed domiciled is set to be removed. This means assets inside previously protected offshore trusts could fall within the UK IHT net.

Strategic Options for HNWIs

With the end of the non-dom regime looming, wealthy residents generally fall into three camps: those who will stay and pay, those who will restructure, and those who will leave. Here are the primary strategies.

1. The “Stay and Pay” (With Optimization)

For those with deep ties to the UK (family, business, lifestyle), leaving may not be an option. The focus here shifts to utilizing the Temporary Repatriation Facility to clean up offshore structures efficiently and using domestic tax wrappers.

However, you must be wary of UK Controlled Foreign Company (CFC) rules. If you continue to hold offshore companies, the profits may be attributed to you personally, negating the benefits of holding cash in a corporate shell.

2. Restructuring Offshore Wealth

While standard offshore trusts are losing IHT protection, other vehicles may still offer benefits. Family Investment Companies (FICs) remain a popular domestic alternative, allowing for control and income accumulation at corporate tax rates (currently 25%) rather than personal income tax rates (up to 45%).

For asset protection, understanding the difference between simple offshore holdings and robust legal structures is vital. You can read more in our guide on asset protection: offshore vs UK Ltd.

3. Relocation: The “Exodus” Option

For many mobile HNWIs, the new 10-year IHT tail and worldwide tax rates are a trigger to leave. But where to go? The destination must offer not just tax efficiency, but lifestyle and infrastructure.

Dubai and the UAE

The UAE remains a top destination due to its 0% personal income tax and lack of inheritance tax. With the introduction of Golden Visas, it has become a viable long-term home for British expats. A case study of a UK agency moving to Dubai demonstrates how significant the tax savings can be for business owners.

To execute this, you must properly break UK tax residency. This often requires obtaining a Tax Residency Certificate in your new jurisdiction to prove to HMRC that you have genuinely left.

Gibraltar and the Channel Islands

For those wishing to stay closer to Europe and the UK time zone, Gibraltar offers a “Category 2” status for HNWIs, capping tax liability on worldwide income. Comparing Gibraltar vs UK company formation highlights the distinct advantages of the jurisdiction for holding companies.

Similarly, Jersey and Guernsey remain stalwarts of private wealth, though they are often more expensive to access. Our Channel Islands company formation comparison breaks down the nuances between the bailiwicks.

Banking and Compliance in the New Era

If you choose to leave the UK or restructure, banking becomes a critical bottleneck. UK banks are increasingly de-risking and closing accounts for non-residents. Conversely, opening offshore accounts requires navigating strict compliance checks.

Whether you are looking at the best offshore banks for UK residents (or soon-to-be non-residents) or need specific functionality like crypto-friendly offshore banks, ensuring you have liquid access to your capital is paramount before triggering a tax residency split.

Conclusion

The end of the non-dom regime marks a generational shift in UK tax policy. For HNWIs, the window for planning is narrowing. The new FIG regime offers a soft landing for new arrivals, but for long-term non-doms, the removal of IHT protections and the remittance basis demands immediate action.

Whether your strategy involves utilizing the Temporary Repatriation Facility, restructuring into a Family Investment Company, or relocating to a low-tax jurisdiction like Dubai or Gibraltar, the key is to act before the April 2025 deadline.

FAQ

What is replacing the non-dom regime in the UK?

The non-dom regime is being replaced by a residence-based system known as the Foreign Income and Gains (FIG) regime. From April 2025, new arrivals to the UK will have a 4-year exemption on foreign income and gains. After this period, they will pay UK tax on worldwide income, regardless of domicile.

What happens to my Excluded Property Trust after 2025?

Under the new proposals, the protection from Inheritance Tax (IHT) for Excluded Property Trusts settled by non-doms is set to be removed. If you meet the residence criteria (10 years of UK residence), assets within these trusts may fall within the scope of UK IHT.

What is the Temporary Repatriation Facility (TRF)?

The TRF is a transitional measure proposed to allow former remittance basis users to bring pre-existing foreign income and gains into the UK at a reduced tax rate (proposed at 12%) for a limited period, likely the tax years 2025/26 and 2026/27.

Can I avoid the new IHT rules by leaving the UK?

Yes, but there is a "tail." If you have been a UK resident for 10 years or more, you will remain liable for UK Inheritance Tax on your worldwide assets for 10 years after you leave the country.

Is Dubai a good alternative for UK non-doms?

Dubai is a popular alternative because it has no personal income tax, capital gains tax, or inheritance tax. However, moving there requires properly breaking UK tax residency and establishing genuine economic substance in the UAE.
