Don’t arrive in the UK with uncertainty around your tax.
Moving to the UK is an exciting opportunity.
But if you don’t understand how the UK tax system works from the start, it can quickly lead to confusion, unexpected tax bills, and missed opportunities.
Before you move, there are some important questions you need clear answers to:
These are not things you want to figure out after you’ve arrived.
The decisions you make before and shortly after arriving can affect your tax position for years.
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.
Without correct planning, two countries can simultaneously and legitimately claim tax on the same earnings.
You must notify HMRC of residency changes even when no tax is due. Missing this triggers automatic penalties that compound over time.
The timing of asset disposals relative to your departure date can make an enormous difference. Once you’ve moved, that window closes permanently.
Your UK tax position starts with your tax residency status, determined by the Statutory Residence Test (SRT).

A person moving to the UK becomes a tax resident under the Statutory Residence Test (SRT), and key indicators are:
if you spend 183 days or more in the UK,
have their only or main home there
work full-time in the UK.
If none of these apply, residence depends on how many days they spend in the UK combined with their ties (such as family, accommodation, or work), and in some cases, the tax year may be split (SYT), so the individual is treated as resident only from the point they effectively settle in the UK, and not pay tax on their income prior to coming to the UK.
A non-UK resident who comes to the UK only needs to report UK-source income to HM Revenue & Customs. This generally includes:
If split-year treatment (SYT) does not apply, income whilst non-resident will be payable in the UK in the year of immigration; the UK tax resident system is that you will be taxed on your worldwide income each year that you are a UK tax resident
Briefly, the main UK personal tax allowances include:
Personal Allowance – the amount of income you can earn tax-free each year (standard allowance, subject to income limits)
Marriage Allowance – allows a lower-earning spouse/civil partner to transfer part of their allowance
Blind Person’s Allowance – extra tax-free amount if you’re registered blind
Trading and Property Allowances – small tax-free amounts for casual trading or property income
Dividend Allowance – tax-free amount for dividend income
Personal Savings Allowance – tax-free interest on savings (amount depends on your tax band)
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:
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
The UK has over 130 double taxation treaties with other countries, agreed by HM Revenue & Customs.
They are not all the same—while they follow broadly similar principles (based on OECD models), each treaty is individually negotiated, so the rules on things like:
Vary from country to country, so you will need our professional advice to navigate the DTT that applies to you
