UK Exit Tax: Everything You Need To Know in 2026

In 2025, UK media reported that the country’s Chancellor of the Exchequer, Rachel Reeves, was considering imposing a 20% tax on high-net-worth individuals who leave the country. After a negative reaction from the wealth industry and various think tanks, the idea was reportedly dropped, at least for now.

In this article, we’ll examine the UK exit tax and explore the different rules for individuals and companies. We’ll also look into the various negative consequences of losing UK residence and offer advice on how to plan your exit to protect your wealth.

What Is an Exit Tax?

An exit tax is a term that describes the application of a certain tax after an exit event, such as:

• Losing the tax resident status in a certain country
• Renouncing citizenship or long-term residence status

The usually levied tax is capital gains tax on unrealised assets, though the type of tax and the triggering event may vary from one jurisdiction to another. The exit mainly targets financial assets and business interests, sometimes even including items like jewelry, art, or collections. The types of assets that are usually exempt include primary residences, pensions, and retirement accounts. 

Many countries calculate the exit tax using a mechanism called deemed disposition. Under this mechanism, the taxable assets are treated as if they had been sold and reacquired at the current market value, and any realized gains are then subject to taxation. 

Some countries use deemed acquisition, treating your property as acquired when you become a resident. This ensures you’re taxed only on gains realized while being a resident, which aligns with the main purpose of exit taxes: making sure taxpayers pay their fair share.

Does the UK Have an Exit Tax?

The UK doesn’t have an exit tax. The 2025 Budget address didn’t include any of the leaked provisions regarding a UK exit tax, but it did make some important announcements: 

• The freeze on personal tax thresholds and the National Insurance contributions secondary threshold will continue 
• Taxes on dividends, property, and savings income will be increased
• A new High Value Council Tax Surcharge will be introduced, affecting homes worth more than GBP 2 million
• Taxes on online gambling will increase 
• The duty relief on low-value imports will be removed to reduce the unfair advantage foreign budget online retailers have over UK businesses

Although the government didn’t introduce an exit tax in this budget, it could still do so in the future. The UK remains an outlier among developed countries, most of which have some form of exit tax. 

What Would an Exit Tax in the UK Look Like?

The information on the UK exit tax proposal didn’t include many key details, like possible exclusions and thresholds. The three details that were mentioned included:

1. The tax rate of 20%
2. No application to profits made before becoming a UK tax resident
3. Provisions for payment deferral

For comparison, here are what other countries’ exit taxes look like:

Country	Who Is Affected	The Tax Rate
The U.S.	Citizens who relinquish citizenship and long-term residents who lose this status and meet one of the following conditions:  ● An average annual net income in the past five years above the year-specific thresholds (USD 206,000 for 2025) ● A net worth above USD 2 million ● Non-compliance with U.S. tax regulations, regardless of their income	Capital gains tax (up to 20%) on gains above the statutory exclusions (USD 890,000 for 2025)
Canada	Residents who leave Canada and sever their residential ties	Personal income tax (combined federal and provincial) up to 54.8% on 50% of the gains
France	Individuals who stop being tax residents, and meet the following conditions: ● Were a tax resident for at least six years of the previous 10 years ● Own shares worth more than EUR 800,000 or half or more of the company’s profits	30% tax on gains (12.8% income tax and 17.2% social contributions)

Beyond the UK Exit Tax: Does Leaving the UK Trigger Other Taxes?

While leaving the UK doesn’t automatically trigger tax liabilities, losing your tax resident status may invoke certain rules that impose additional tax obligations. The most important ones include:

1. Temporary non-residence rule
2. Loss of allowances
3. Inheritance tax tail

Temporary Non-Residence Rule

If you’re deemed a temporary non-resident, you might be liable for capital gains and income taxes for the period when you weren’t a UK resident. You are considered a temporary non-resident if you meet the following criteria: 

Criterion	Requirement
Non-residence duration	Five years or less
Prior UK residence	UK tax resident for at least four of the previous seven years
Status before departure	UK resident in the tax year of departure (which may be treated as a split year)

As a temporary non-resident, you may be required to pay tax on all capital gains you realized while you weren’t in the UK. The only exception is the gains from assets you acquired while residing abroad. 

The income you might be taxed on includes:

• Certain pension and retirement payments and withdrawals
• Foreign income remitted to the UK 
• Gains on life insurance, life annuities, or capital redemption policies
• Dividends by close companies, excluding trade profits

To avoid being treated as a temporary non-resident, it’s important to keep your non-residence status for more than five years. 

Loss of Allowances

The UK has certain tax allowances that can reduce your tax liability. As a non-resident with UK income or capital gains, the two most important allowances you might lose due to the change in your residency status are:

1. Personal allowance, which gives a tax-free status to GBP 12,570 of your yearly income
2. Capital gains tax exempt amount, which gives a tax-free status to GBP 3,000 of your capital gains in any year

It’s important to note that you will not lose your personal allowance as long as you maintain citizenship of the UK or another EEA country. Additionally, the capital gains exemption amount has been drastically reduced in recent years.

Inheritance Tax Tail

If you’re a UK long-term resident, your full estate will be subject to the inheritance tax (IHT), following recent reforms. Once you stop being a long-term resident, the UK portion of your estate can remain taxable. When it comes to taxation of your foreign estate, you may still be considered a long-term resident for a specific period, even after you stop fulfilling the criteria of long-term residence. 

This period is usually called an IHT tail, and it can stretch for up to 10 years, depending on how long you’ve been a long-term resident of the UK:

• Between 10 and 13 years of residency: Three years of an IHT tail
• Every additional year of residence: One additional year of the tail

If you’ve been a UK long-term resident for 20 years, your overseas estate will be subject to the IHT for 10 years after leaving the UK. Returning to the UK after 10 years resets the long-term residence test for IHT purposes.

How To Plan an Exit Strategy From the UK: 4 Points of Action Explained 

While it might be impractical to start planning for a tax that hasn’t yet been levied, there are certain steps you can take to prepare for it. You might also consider some general steps that have helped people avoid tax traps when leaving the UK:

1. Start planning your exit from the UK early
2. Familiarize yourself with the Statutory Residence Test 
3. Determine split-year treatment
4. Enlist professional help

1. Start Planning Your Exit From the UK Early

It’s reasonable to expect that the UK will, at some point, introduce an exit tax. To avoid it, it’s best to start planning the exit as soon as possible. Leaving a country of residence is a lengthy process, and it becomes more complicated depending on the amount of assets you want to preserve from taxation.

The process involves more than just deciding which assets to liquidate and when. If you don’t have a backup passport or at least residency in another country, you’ll have to obtain one, and that takes time. You’ll also have to move there in person, which may involve complex logistics. 

2. Familiarize Yourself With the Statutory Residence Test

The Statutory Residence Test (SRT) enables you to determine whether you were a UK tax resident in any given year. Understanding the residency criteria is crucial for planning your exit, as it can help you confirm: 

• How much time you can spend in the UK without being considered a resident
• What types of activities you can undertake in the country 
• What counts as ties to the country 
• How all of the above might affect your estate for inheritance tax purposes

3. Determine Split Year Treatment 

The UK tax system allows you to claim a split year. This means you’ll be treated as a UK tax resident for one portion of that year, and a foreign country resident for the rest of the year. 

The split year implies that you’ll be shielded from UK taxation for the portion of the year that you spend overseas, which is an important consideration when planning your exit. Like most rules in the Statutory Residence Test, determining split years can be complicated and may require professional guidance.

4. Enlist Professional Help

Deciding what to do with your assets—whether to offshore, sell, restructure, or retain them—and when to act is one of the core considerations of planning your exit if you want to preserve your wealth. This is best handled with the support of professional accountants or business advisors with experience in international tax and cross-border planning.

You may also benefit from getting professional guidance on the UK residence and tax laws from a solicitor or legal advisor. These laws are complex, and even the smallest errors in interpretation can have significant consequences. 

Finally, consider engaging global mobility professionals who can help you identify the most suitable country for residence and the most efficient way to relocate. They can ensure you meet all of the host country’s regulatory requirements and navigate the relocation process seamlessly.
