Understanding the Basics of UK Residency Rules

UK residency rules provide a framework that determines your legal status and the rights and obligations you hold within the UK. 

Under UK residency rules, the term ‘residency’ primarily refers to the location where a person has a permanent or habitual home. 

If you stay in the UK for 183 days or more in a tax year, you’re typically considered a resident. However, you could also be a resident if your home, family, or work is in the UK. 

UK residency rules can be complex, and it’s essential to understand how they apply to your specific situation.

Different Categories of Residency Status

UK residency rules recognize different categories of residency status, each with its own implications for matters like taxation and access to services. Let’s delve into the key categories: Ordinary Residence, Domicile, and Non-Domicile.

Ordinary Residence

‘Ordinary residence’ is a term used in UK residency rules to define individuals who frequently live in the UK, making it their regular home. It applies even if you occasionally leave for holidays or business trips as long as you intend to return to the UK.


‘Domicile’ is another category recognized in UK residency rules. It refers to the country that a person considers their permanent home or where they have a substantial connection. Domicile is a complex area of law and is significant for tax purposes, as the UK taxes individuals based on their domicile status.


Under UK residency rules, a non-domiciled person is someone who lives in the UK but considers another country as their permanent home. Non-domiciles might live and work in the UK but retain a strong connection with their country of origin. They may be subject to different tax rules depending on their income and assets held abroad.

How UK Residency is Determined: The Statutory Residence Test (SRT)

In UK residency rules, determining one’s residency status is achieved primarily through the Statutory Residence Test (SRT). 

Introduced in 2013, the SRT provides a clear, step-by-step process to establish whether an individual is a UK resident for tax purposes. 

This test comprises three components: the Automatic Overseas Test, the Automatic Residence Test, and the Sufficient Ties Test.

Automatic Overseas Test

The Automatic Overseas Test is the first part of the SRT. If you pass this test, you are considered a non-resident under UK residency rules, irrespective of other circumstances. 

There are three conditions under this test, including spending fewer than 16 days in the UK during a tax year if you were a resident in one of the previous three tax years. 

The specifics can be quite detailed, so it’s wise to seek professional advice if you’re unsure about your status.

Automatic Residence Test

If you don’t meet the criteria for the Automatic Overseas Test, you proceed to the Automatic Residence Test as per UK residency rules. 

This test considers several factors, including whether you’ve spent 183 or more days in the UK during the tax year, whether you have a home in the UK where you’ve stayed for at least 30 days, or whether you’ve carried out full-time work in the UK for 365 days with no significant breaks. Meeting any of these criteria typically qualifies you as a resident.

Sufficient Ties Test

Lastly, if neither the Automatic Overseas Test nor the Automatic Residence Test determines your residency status, you would consider the Sufficient Ties Test. 

UK residency rules use this test to consider the number of ties or connections you have with the UK, such as family, accommodation, work, and the amount of time you spend in the UK compared to other countries. The more ties you have, the less time you need to spend in the UK to become a resident.

Tax Implications for Expats under UK Residency Rules

UK residency rules not only determine your status but also significantly impact your tax obligations. The tax system in the UK operates on both residency and domicile status. 

Whether you’re considered a resident or non-resident, you will face different tax implications. Let’s delve into these details:

Taxation for UK Residents

Under UK residency rules, if you’re a resident, you’re typically subject to tax on your worldwide income and gains. This means that income and capital gains from outside the UK are usually taxable here, regardless of whether you bring the money into the country. 

However, the UK has double taxation agreements with many countries, which means you won’t be taxed twice on the same income.

Taxation for Non-Residents

UK residency rules provide that non-residents are usually taxed only on income earned within the UK. This could include income from UK-based employment, rental income from UK property, or income from a business operated in the UK. 

However, non-residents are generally not liable for UK tax on foreign income, even if they bring the money into the UK.

Remittance Basis of Taxation

The remittance basis of taxation is a special set of rules under the UK tax system that applies to ‘non-domiciled’ residents. Under UK residency rules, individuals can choose to be taxed on a remittance basis, meaning they pay UK tax only on the foreign income or gains they bring to the UK. 

However, choosing the remittance basis could lead to losing some tax allowances and may involve an annual charge if you’ve been a UK resident for a certain number of tax years.

Impact of UK Residency Rules on Property Ownership

UK residency rules do not just affect tax status but also property ownership and associated taxes. The rules differ for residents and non-residents, making it important for expats to understand their implications.

Under UK residency rules, residents are free to purchase property in the UK without any restrictions. However, it’s important to note that owning a home can affect your status under the Statutory Residence Test, which may impact your tax liabilities. 

When selling a property, UK residents may be subject to Capital Gains Tax on any profits, with some exceptions, like the sale of a primary residence.

Non-residents can also purchase property in the UK under UK residency rules. But as a non-resident, you may be liable for Non-Resident Capital Gains Tax (NRCGT) when you sell the property. 

Furthermore, owning a property in the UK can affect your residency status under the Statutory Residence Test.

UK residency rules not only determine your status but also significantly impact your tax obligations.

Social Security Benefits as an Expat in the UK

UK residency rules also impact your eligibility for social security benefits. These benefits can form an important part of your financial security while living in the UK.

As an expat, your eligibility for social security benefits in the UK depends on several factors, including your immigration status, your work history, and your contributions to the National Insurance scheme. UK residency rules play a role in determining your eligibility for certain benefits.

UK residency rules stipulate that your eligibility for certain social security benefits depends on your residency status. 

For example, to claim the State Pension, you must have been a resident in the UK for at least 10 years. Other benefits may require you to pass the Habitual Residence Test, demonstrating that the UK is your main home.

Healthcare Rights Under UK Residency Rules

When relocating to a new country, understanding your rights to healthcare services is paramount. 

In the context of the UK, the healthcare system is managed by the National Health Service (NHS). The UK residency rules dictate your access to these services.

Access to National Health Service (NHS)

Under UK residency rules, expats who are considered residents have full access to the NHS, which is free at the point of service. 

However, as a UK resident, you may have to pay a healthcare surcharge as part of your immigration application, also known as the Immigration Health Surcharge.

Private Healthcare Options for Expats

Private healthcare is also an option for both residents and non-residents in the UK. While UK residency rules do not govern access to private healthcare, the terms of your health insurance might. It’s therefore crucial to confirm the specifics with your provider.

How Does Dual Citizenship Affect UK Residency Status?

Dual citizenship does not directly influence your UK residency status. The UK residency rules are primarily based on how much time you spend in the country rather than your citizenship status. 

If you’re a dual citizen and you spend a significant amount of time in the UK, you may still be considered a resident under UK residency rules. It’s essential to keep in mind that regardless of whether you hold one or multiple citizenship, the same UK residency rules will apply to you.

What Happens to My Residency Status If I Leave the UK for A Long Period?

Under the UK residency rules, if you leave the UK for a long period, you may lose your resident status. The exact definition of ‘long period’ is subject to interpretation under the Statutory Residence Test. 

Generally, if you spend fewer than 16 days in the UK during a tax year, you are considered a non-resident. 

However, various factors, such as ties to the UK, accommodation availability, and work commitments, can affect this status. 

Therefore, it’s important to understand the specifics of UK residency rules or seek professional advice before planning an extended absence from the UK.

Can I Maintain My Non-Domicile Status If I Become a UK Resident?

Yes, according to the UK residency rules, you can be a resident in the UK and maintain your non-domicile status. 

However, the benefits of non-domicile status, especially concerning taxation on overseas income, often require you to pay a remittance basis charge. This charge applies if you’ve been a UK resident in at least seven of the previous nine tax years and want to maintain access to the remittance basis of taxation.

According to the UK residency rules, you can be a resident in the UK and maintain your non-domicile status. 

How Does the UK Residency Affect My Spouse and Children?

UK residency rules apply on an individual basis, meaning each person’s status is determined separately. However, your residency status can impact your family’s rights, especially regarding the ability to work or access public funds. 

For example, if you are a resident and your spouse or children are dependants on your visa, they generally share your residency rights. However, they will need to meet individual UK residency rules to claim certain benefits or to pay taxes.

How Do I Change My Residency Status in the UK?

Changing your residency status under UK residency rules usually involves altering your lifestyle, such as spending more or less time in the country. However, the Statutory Residence Test takes various factors into account, not just the length of stay, so changing your status may not be straightforward. 

Additionally, changes in residency status can have significant implications for tax and access to services. Therefore, before you attempt to change your residency status, it’s recommended to get professional advice to understand the full implications of UK residency rules.
