What Happens to Your UK Tax When You Move Abroad?

Before you leave, there are some important questions you need clear answers to:

These are not things to figure out once you’ve already moved.

The decisions you make now will shape your tax position for years.

01

Unexpected tax bills — months later

HMRC can investigate and assess tax going back years. A residency miscalculation at the point of departure can resurface long after you’ve settled in.

02

Paying tax twice on the same income

Without correct planning, two countries can simultaneously and legitimately claim tax on the same earnings.

03

HMRC penalties for missing notifications

You must notify HMRC of residency changes even when no tax is due. Missing this triggers automatic penalties that compound over time.

04

Lost window for Capital Gains planning

The timing of asset disposals relative to your departure date can make an enormous difference. Once you’ve moved, that window closes permanently.

Why Timing Matters More Than You Think

A few days can change everything.

The exact date you leave the UK can affect your tax residency status under the Statutory Residence Test (SRT).

Get the timing wrong and you could:

Remain UK tax resident when you didn’t expect to
Pay more tax than necessary
Miss opportunities like Split Year Treatment (SYT)
Trigger HMRC penalties or compliance issues

Get it right and you can:

Will You Still Pay UK Tax After You Leave?

Leaving the UK doesn’t always mean leaving the UK tax system.

You may still need to pay tax on:

You may also need to consider Capital Gains Tax (CGT) if you sell assets while abroad or return to the UK later.

Without the right advice, it’s easy to:

Pay more tax than you need to
Be taxed twice in different countries
Miss reporting deadlines with HMRC

Avoid Costly Mistakes Before You Move

Most problems we see happen because people wait too long.

Once you’ve left the UK, your options can be limited.

Before you go, you have the opportunity to:

Leaving the UK doesn’t automatically stop UK tax.

  • If you remain UK tax resident, you’ll still be taxed on your worldwide income
  • When you leave the UK, you must undertake the statutory residence test (SRT)
  • If SRT determines that you’ve become non-resident, then unless split year testament (SYT) applies, you’ll be taxed on your worldwide income for the year of departure
  • When you become non-resident, the UK generally taxes only your UK income and gains (e.g. property, UK work)

Your tax depends on your residence status and UK connections, not just the fact you’ve left, and we will guide you through the SRT and SYT process

Leaving the UK doesn’t automatically remove the need to file a tax return.

You may still need to complete a Self-Assessment return if you:

  • Need to confirm your residence status (including split-year treatment (SYT))
  • Need to file at least one return to finalise your UK tax position (and possibly get a tax rebate)
  • Have UK income or gains (e.g. rental income, UK work, property sales)
  • Receive a notice from HM Revenue & Customs to file

We can help you with all of your tax compliance requirements, both when you leave and if necessary, on an ongoing basis

Yes, you can be taxed in two countries at once, but you are not usually taxed twice on the same income.

This can happen because:

  • One country taxes you based on residence (e.g. where you live), and
  • Another taxes you based on source (e.g. where the income arises)

For example, the UK may tax you on income earned within its borders, while another country taxes you as a resident

However, double taxation treaties (DTT) and domestic rules are designed to prevent you paying tax twice on the same income. Typically, one country has the primary right to tax, and the other gives relief (usually a tax credit) for tax already paid.

We can help you determine where you will pay taxes under the DTT

UK income is usually still taxable after you leave.

  • Rental income: taxed in the UK on net profits
  • UK dividends: generally still taxable, though treatment can vary (including something called disregarded income)
  • Other UK income: (e.g. work done in the UK) remains within the UK tax net

Even as a non-resident, the UK continues to tax UK-source income, especially property, and we can guide you on your future tax planning and ongoing compliance

You need to tell HMRC as soon as your circumstances change—and report it formally after the tax year.

  • When leaving the UK: notify HMRC (often via form P85 or your tax return)
  • When arriving in the UK: register for Self-Assessment if you have taxable income
  • After the tax year ends, complete a tax return including residence details (SRT)

You should tell HMRC about:

  • Your departure or arrival date per the statutory residence test (SRT)
  • Changes to your residence status
  • Any UK income or gains
  • Claims such as split-year treatment (SYT)

We will handle all of your notifications to HRC and any ongoing tax reporting, so you know that this is all safe and taken care of

Non-residents still pay UK tax on UK property income and gains.

  • Rental income: taxed in the UK on net profits (after allowable expenses)
  • Capital gains: UK tax applies when you sell UK property, even if you’re non-resident
  • You will need to file a UK Self-Assessment tax return
  • The Non-Resident Landlord Scheme will apply to rental income

Being non-resident does not remove UK tax on UK property; the UK always taxes UK land and property and our specialist team will be able to assist you with all your compliance requirements

Leaving the UK doesn’t always remove UK tax.

  • UK dividends: these need to be carefully checked on a case-by-case basis
  • Investments (shares/gains): usually outside UK tax, unless you return within 5 years (temporary non-residence rules)
  • UK pensions: typically still taxable in the UK, though a double tax treaty may change this, and pay attention to the NT code

NT tax codes:

  • An NT (“No Tax”) code means no UK tax is deducted at source
  • It’s often used where a treaty gives another country the primary taxing right
  • It does not mean the income is tax-free—just that tax is dealt with elsewhere

Some UK income falls outside UK tax when you leave; but pensions and timing issues mean you need to check carefully. We work with great financial advisers that can assist with your investment and pension advice wherever you are in the world – contact us for details.

Your UK business income may still be taxed in the UK after you leave.

  • If a sole trader continues to operate in the UK, profits remain taxable in the UK
  • If you carry on the business from overseas, tax depends on whether there is a UK presence (permanent establishment)
  • You may also have tax obligations in your new country of residence

Leaving the UK doesn’t remove UK tax on a UK-based business; it depends where the business is actually carried on and managed, and we can advise you on your UK tax liabilities.

Different types of UK earnings are taxed in different ways, especially if you are non-resident.

  • Employment income: taxed where the work is physically done
  • Rental income: always taxed in the UK if the property is in the UK
  • Dividends: generally not taxed in the UK for non-residents
  • Pensions: often taxable in the UK, but may be affected by a double tax treaty
  • Capital gains: usually not taxed for non-residents—except UK property

Not all income is treated the same; the type of income and where it arises determines how it’s taxed and that’s why you need our expert help to navigate your planning
