" Jacob is fast, structured, and deterministic. He responds quickly, gives clear and definitive answers where the law allows, and doesn't hide behind vague replies. He knew the expat and non-resident space cold — no need to "look into it later." The written advisory memo was clear and actionable, and the tax return was prepared and filed efficiently with minimal back-and-forth. If you're a non-resident, digital nomad, or expat dealing with a complex tax situation, I'd strongly recommend Jacob. He's exactly the kind of advisor you want in your corner. "

Frequently Asked Questions – Tax Advice When Leaving the UK

What tax advice should I get when leaving the UK?

When leaving the UK, it’s important to get advice on your UK tax residency status, Capital Gains Tax, and income tax on ongoing UK-sourced income. It is essential to seek advice as soon as possible to break UK tax residence and minimise your UK tax exposure.

Do I still need to pay UK tax after leaving the UK?

If you become UK tax non-resident, you may still need to pay UK tax on UK-sourced income, such as rental income, pensions, or dividends. However, certain UK rules and Double Taxation Agreements may mean you no longer pay any UK tax. If you become non-resident and have no ongoing UK-sourced income, you shouldn't expect to have to pay any UK tax.

How do I become non-resident in the UK?

Your UK tax residence status is determined by the Statutory Residence Test, which assesses your UK time, location of homes and family. We recommend that expert advice is obtained to determine your UK tax residence status and how many days you can spend in the UK.

Do I need to tell HMRC that I’m leaving the UK?

You do not need to inform HMRC that you have left the UK. However, you will need to inform them of any ongoing UK taxable income or to claim a UK tax refund if you are entitled to one. This is done via Form P85 or a self-assessment tax return, and the optimal approach depends on your specific circumstances.

Do I need to pay Capital Gains Tax when leaving the UK?

Non-residents pay Capital Gains Tax on disposals of UK property and land, and additional reporting requirements apply that differ from those for residents. You may also need to pay Capital Gains Tax on assets that you sell while non-resident if you return to the UK within five years.

How does double taxation relief work when leaving the UK?

If you move to a country that has a double tax treaty with the UK, you can usually claim relief to avoid being taxed twice on the same income. This is particularly relevant for individuals who remain UK tax resident; however, non-residents can also claim relief.

How will my UK pension be taxed if I live overseas?

UK pension income is UK-sourced and therefore remains taxable in the UK after you leave. However, if you move to a country that has a double taxation agreement with the UK, it may be possible to exempt your pension income in one country to prevent double taxation.
