When expatriates depart the United Kingdom to establish residence overseas, their UK tax obligations do not simply vanish. This guide provides an overview of the essential aspects of filing UK tax returns while residing abroad and outlines the specific deadlines that expatriates must adhere to.
It is important to note that expatriates do not immediately lose their UK tax-resident status upon leaving the country, and they are still required to submit tax returns from their foreign place of residence if they earn any income within the UK.
Managing one’s tax responsibilities from a foreign location can be a challenging endeavor. The demands of daily life often take precedence, and the additional complications stemming from international time zone disparities can further exacerbate the situation.
Verifying Your Tax Residency Status
The fundamental factor that governs the taxation of expatriates is their residency status. Residency determines both the jurisdiction in which you are obligated to pay taxes and the amount you are required to pay.
If you find yourself on an international assignment but have intentions to return to your home country within a year or two, there is a strong likelihood that you will maintain your UK tax residency even while living abroad. In such a scenario, your tax obligations to the UK, including income and capital gains taxes, persist, and you may continue to benefit from tax advantages such as pension contribution relief.
Conversely, when you transition to non-resident status, the tax rules undergo a shift. You will then be subject to income and other tax regulations in accordance with the rules of your current place of residence, and you will forfeit any tax benefits tied to the UK.
In many countries, tax residency is primarily determined by the duration of your stay, typically requiring more than 180 days of residence in a specific location to establish tax residency.
To begin the process of ascertaining your tax liability in the UK, the initial step is to undergo the Statutory Residence Test (SRT). This assessment guides expatriates in evaluating their residency status and clarifies whether they are classified as tax residents of the UK or of a foreign jurisdiction.
In addition to confirming their UK tax residency, expatriates should also seek advice from immigration professionals in their new host country to determine if they have also acquired tax residency status in that location.
Double Tax Agreements
Bilateral tax agreements (also known as Double Taxation Agreements or DTAs) may appear intricate at first glance, but they are essentially a set of regulations established between countries to determine priority in taxing your income.
Contrary to initial impressions, double taxation, in the context of these agreements, serves a beneficial purpose by preventing individuals from being taxed twice on the same income or gains.
The concept is straightforward:
In the first country, an expatriate is required to pay taxes on the income earned there, and they receive a certificate confirming the payment of tax.
In the second country, which also seeks to tax the same earnings, the expatriate presents the tax certificate from the first country to the tax authority. This action effectively eliminates the need to pay taxes again on the same income.
Naturally, the specifics of double taxation agreements can be more intricate, but this simplified example provides a basic understanding of how DTAs function.
Tax Reporting for Expatriates in the UK
Once your UK residency status is determined through the Statutory Residence Test, you become liable to pay taxes in the UK on your global income and gains.
As an expatriate, your UK tax obligations encompass the following sources of income:
- Private UK pensions (excluding QROPS)
- Rental profits
- Savings interest
- Any other income earned within the UK
The UK tax year spans from April 6 one year to April 5 the following year. Consequently, you are required to complete a self-assessment tax return and settle any owed taxes by midnight on January 31 following the conclusion of the tax year.
For instance, if you left the UK in September 2021, you must file self-assessment returns for the tax years ending on April 5, 2021, and April 5, 2022. The deadline for the 2021 return is January 31, 2022, and for the 2022 return, it’s January 31, 2023.
In cases where you’ve departed the UK but need to seek tax relief or request a refund, you can do so by submitting a Form P85.
Non-residents do not have access to the HM Revenue & Customs (HMRC) online portal. Instead, they can choose to file by post or engage an agent for this purpose. The deadline for expatriates using an agent or commercial tax software for filing is also January 31.
To file taxes online, expatriates need a Government Gateway account and a Unique Tax Reference (UTR). It’s advisable to apply for both well in advance, as the application process may take several weeks to complete.
Alternatively, you can obtain a paper tax return from the HMRC website for manual filing.
Managing Your Finances as an Expat
In certain expatriate destinations known for their political and economic volatility, safeguarding your financial assets from risk is a prudent move.
Traditionally, expatriates strive to maintain a UK bank account, but this has become increasingly challenging as financial institutions now often require customers to have a UK address.
Fortunately, many reputable UK banks have offshore branches that offer a range of current and savings accounts in both British Pounds and various foreign currencies. These offshore branches are typically located in the Isle of Man or the Channel Islands.
These offshore accounts serve as a secure intermediary and a form of financial protection in uncertain environments. The majority of funds are kept offshore, while smaller, regular transfers are made to cover day-to-day expenses in the local currency.
Savings and Investment Strategies for Expatriates
One’s tax residency status significantly influences the manner in which expatriates save and invest their financial resources.
For those who maintain UK tax residency, the standard array of UK financial products and associated tax benefits, such as pension contribution tax relief, remains accessible.
Conversely, for those no longer classified as UK residents, expatriates have the option to save and invest within the jurisdiction of their current residence. Non-UK residents can also explore offshore solutions for tax-efficient investments, such as the Qualifying Recognised Overseas Pension Scheme (QROPS) or investment bonds. However, be careful as these are often misused by IFAs for commission for further reading on these topics and others highly recommend-

Summary
A subject that confuses a lot of people, there are some key places you can go, such as the Government website and tax advisors who will help you to decipher the details I’ve tried to create a general guide to help expats as it’s a very common question.
I would be mindful of the different types of taxes there are and if you have assets which one it might trigger. As an expat you might incur what I’d class as standard tax on income and if you have any assets that you sell, that might trigger Capital Gains Tax. For many expats, they might invest in property in the UK which can incur taxes, but if they sell, it can incur Capital Gains Tax.
Understanding the different types, and what you need to pay in your situation will help you plan your next steps. It’s important to know the tax you are required to pay in your country of residence to make sure you are abiding by law.
