Tax is one of the most important — and most confusing — aspects of moving to the UK. Whether you're employed, self-employed, or receiving income from multiple sources, understanding how UK tax works is essential for managing your finances and staying on the right side of HMRC. In this guide, we explain the UK tax system in plain English, with the latest rates and thresholds for 2026/27.
The Basics: How UK Tax Works
The UK tax system is based on residence, not citizenship. This means:
- If you are UK tax resident, you pay UK tax on your worldwide income
- If you are not UK tax resident, you generally only pay UK tax on income earned in the UK
- Your nationality does not determine your tax status — where you live does
The UK tax year runs from 6 April to 5 April — different from most other countries. This is important for understanding tax deadlines and residency calculations.
Are You a UK Tax Resident?
Your tax residency is determined by the Statutory Residence Test (SRT). As a general guide:
- If you spend 183 or more days in the UK in a tax year, you are automatically UK tax resident
- If you spend fewer than 16 days in the UK, you are automatically non-resident
- Between these thresholds, your residency depends on how many "ties" you have to the UK (family, accommodation, work, etc.)
💡 For most expats moving to the UK on a visa, you will become UK tax resident from the day you arrive and start living here. This means you pay UK tax on your UK income from day one.
💡 New in 2025: A four-year foreign income and gains (FIG) regime started from 6 April 2025, which may benefit new UK residents by exempting certain foreign income in their first four years. Consult a tax adviser if you have significant overseas income.
UK Income Tax Rates 2026/27
In England, Wales, and Northern Ireland, income tax is charged in three bands:
| Tax Band | Taxable Income | Tax Rate |
|---|---|---|
| Personal Allowance | Up to £12,570 | 0% — tax free |
| Basic Rate | £12,571 – £50,270 | 20% |
| Higher Rate | £50,271 – £125,140 | 40% |
| Additional Rate | Over £125,140 | 45% |
💡 Scotland has different income tax rates — with 6 bands ranging from 19% to 48%. If you live in Scotland, check the Scottish Government website for the latest rates.
⚠️ Personal Allowance reduction: If your income exceeds £100,000, your Personal Allowance is reduced by £1 for every £2 over that threshold — effectively creating a 60% tax rate on income between £100,000 and £125,140.
National Insurance (NI) Contributions
In addition to income tax, most UK workers pay National Insurance (NI) contributions, which fund the NHS, state pension, and other benefits. NI is separate from income tax and has its own thresholds:
| Type | Who pays | Rate 2026/27 |
|---|---|---|
| Class 1 (Employee) | Employed workers | 8% on earnings £12,570–£50,270; 2% above |
| Class 1 (Employer) | Employers | 13.8% on earnings above £9,100 |
| Class 4 (Self-employed) | Self-employed sole traders | 6% on profits £12,570–£50,270; 2% above |
💡 NI and your state pension: You need 35 qualifying years of NI contributions to receive the full UK State Pension. As an expat, every year you contribute counts — it's worth keeping track.
How Tax Is Collected: PAYE vs Self Assessment
There are two main ways UK tax is collected:
PAYE (Pay As You Earn) — For Employees
If you work for an employer, tax and NI are automatically deducted from your salary before you receive it. Your employer handles all the calculations — you don't need to file a tax return unless you have additional income sources. You'll receive a payslip showing your gross pay, deductions, and net pay.
💡 Check your tax code: HMRC assigns you a tax code that determines how much tax-free pay you receive. The most common is 1257L (reflecting the £12,570 Personal Allowance). If your code is wrong, you may pay too much or too little tax. Check at gov.uk/check-income-tax-current-year.
Self Assessment — For Self-Employed and Multiple Income Sources
You need to file a Self Assessment tax return if you are:
- Self-employed with income over £1,000
- A company director
- Earning rental income
- Earning over £100,000 per year
- Receiving foreign income that needs to be declared in the UK
- Receiving Child Benefit and earning over £60,000
The online Self Assessment return deadline is 31 January following the end of the tax year. The tax you owe must also be paid by this date.
Council Tax
Council tax is a local tax paid to your local council — separate from income tax. It funds local services like rubbish collection, parks, and local government. The amount varies by area and property band (A-H), typically ranging from £130 to £250+ per month.
Key exemptions for expats:
- ✅ Full-time students are completely exempt — apply for the exemption through your university
- ✅ 25% discount if you live alone
- ✅ Diplomatic immunity exempts some embassy staff
VAT (Value Added Tax)
VAT is a consumption tax charged on most goods and services in the UK. The standard rate is 20%. If you are self-employed or running a business, you must register for VAT if your annual turnover exceeds £90,000. Once registered, you charge VAT on your sales and can reclaim VAT on business purchases.
Double Taxation: Will You Be Taxed Twice?
Many expats worry about being taxed in both the UK and their home country. The good news: the UK has double taxation agreements (DTAs) with over 130 countries — including France, Germany, the USA, Canada, Australia, and most EU nations. These agreements prevent you from paying full tax in both countries on the same income.
💡 If you have income from both the UK and your home country, consult a tax adviser familiar with both systems. The interaction between two tax systems can be complex, especially in your first year of UK residence.
