UK Non-Resident Tax Rules: 2026 Exit Planning

When you make the decision to leave the UK, your focus is likely on the logistics of your move, finding a new home, arranging visas, and perhaps learning a new language. However, the tax implications of your departure are just as critical. A common misconception is that once you physically leave the UK and become a non-resident, your relationship with HM Revenue & Customs (HMRC) ceases immediately.

The UK operates a "source-based" taxation system for non-residents. This means that while your foreign income and gains fall outside the UK tax net, HMRC maintains a right to tax income that originates within the UK. Understanding what constitutes "UK-sourced income" is the foundation of effective UK exit planning.

In this article, Global Tax Consulting outlines how various income streams are treated once you have established non-residency and how you can manage your compliance obligations effectively.

Determining the Source: Employment Income

If you continue to work after moving abroad, you must understand that the "source" of employment income is determined by where you are physically located when you perform the work. It is not determined by where the employer is based or where your salary is paid.

As a non-resident, you are  only liable to pay UK tax on the portion of your employment income that relates to duties physically performed within the UK. To illustrate this, consider the following example:
‍

• Scenario: You earn a gross salary of £100,000.
• Global Workdays: During the tax year, you work a total of 200 days.
• UK Workdays: During the tax year, you work 20 days in the UK.
• Taxable Amount: HMRC is entitled to tax 10% of your earnings (£10,000), as 10% of your work duties were exercised in the UK.

Note that if you are employed by an overseas company and you are resident for tax purposes in an overseas country, you may be able to go a step further and completely remove the UKs right to tax the UK portion of employment income through reliance on  international tax law, specifically the UKs network of Double Taxation Agreements.
‍

Self-Employment and Business Profits

If you are self-employed, the rules regarding the "source" of income shift toward the concept of "Permanent Establishment" (PE) and location of physical work duties. If you are a non-resident business owner, the UK will only seek to tax your business profits if they are generated through a PE located in the UK or through physical work performed on UK soil.

If your business has a PE in the UK i.e. you have a physical presence, you will be liable to pay tax on the profits associated or generated from the PE.

If you are a digital entrepreneur i.e. you wholly run your business online, you will be liable to pay tax on the portion of profits that relate to work physically exercised in the UK. Similar to employment income, if you are resident for tax purposes in an overseas country, you may be able to go a step further and completely remove the UKs right to tax the UK portion of profits through reliance on  international tax law, specifically the UKs network of Double Taxation Agreements.

If your business does not have a PE in the UK and you wholly work overseas, there is no exposure to UK taxation. 

The Persistence of UK Rental Income

One of the most common forms of UK-sourced income for expats is rental income from a former family home or investment property. Rental income remains 100% taxable in the UK, irrespective of your resident status.

As a non-resident landlord, the starting point is that the estate agent or tenant should withhold basic rate tax from the revenue (similar to PAYE on employment income) however, it is possible to reach out to HMRC to request the revenue is paid gross to you through registering as a non-resident landlord. Details of how to regsiter can be found at the bottom of this article.
‍

Pension Income and International Tax Law

The starting point for UK pension income is that the income is taxable in the UK.

However, depending on the type of pension income and the country you choose to retire, it may be possible to completely remove the UKs right to tax the pension income.

This is because often international tax law gives the resident country the sole taxing right meaning that the UK will not be able to tax the pension income.

Navigating Investment Income: Interest and Dividends

When it comes to bank interest and dividend income, the rules for non-residents offer a significant degree of flexibility. While the starting point is that these are UK-sourced and therefore taxable, many expats can mitigate this liability through the Disregarded Income basis or via international tax law.
‍

• Disregarded Income: For many non-residents, the UK tax liability on "investment income" (like interest and dividends) is limited to the tax deducted at source. If no tax was deducted at source, the liability is effectively nil meaning that you can receive unlimited investment income and not pay tax in the UK.
• Treaty Relief: Alternatively, you may rely on international tax law to limit the UK's taxing right to a specific percentage (often 5%, 10% or 15%) or remove the taxing right entirely.

Retention of the Personal Allowance

A vital component of UK exit planning is determining whether you keep your UK Personal Allowance (the amount of income you can receive tax-free each year). Contrary to popular belief, you do not automatically lose this just because you move abroad.

If you are a UK or EEA national, you continue to qualify for the UK personal allowance even while non-resident. If you are not a UK or EEA national, you may qualify for the personal allowance under a double taxation agreement, which you can view here.
‍

The "Five-Year Trap": Temporary Non-Residence

As part of your exit planning, you must be aware of the temporary non-residence rules which apply if you repatriate to the UK within five years.

The rules are designed to prevent individuals from leaving the UK for a very short period and if triggered, the rules can bring incomes that have been excluded from taxation while abroad, into the scope of taxation upon repatriate - think of it like deferring a tax charge.

If you are planning to be overseas for up to five years, you must plan carefully to avoid unexpected tax charges upon repatriation.

Compliance and Reporting Obligations

Successful exit planning culminates in meeting your compliance obligations.

To achieve a clean break and manage ongoing UK liabilities, you should consider the following steps:
‍

1. Form P85: If you are leaving the UK and will no longer be filing a Self-Assessment tax return (e.g., you have no rental income), you should submit Form P85. This notifies HMRC of your departure and allows you to claim back any overpaid tax on your employment income for the year of departure. You can file P85 form here.
2. Treaty Relief Form: To restrict the UK's tax on pension or investment income under a DTA, you often need to submit a specific treaty relief form, which must be certified by the tax authorities in your new country of residence. You can file treaty relief form here.
3. Self-Assessment: You have a 100% requirement to file a UK tax return if you receive UK rental income. You may also need to file to claim the "disregarded income" basis or to reclaim tax that has been withheld at source on other UK incomes. You can register to file a UK tax return here.
4. Non-Resident Landlord Form: To register as an overseas landlord and to request approval from HMRC that your rental income is paid gross of taxation. You can register as a non-resident landlord here.
