🇬🇧 UK Taxes for Newcomers 2026
Moving to the UK for work means understanding Income Tax, National Insurance, and the Immigration Health Surcharge — three separate charges that together determine your real take-home pay.
Worked example: take-home pay on £41,700
Pension contributions and student loan repayments would reduce this further. Scotland has different income tax bands.
| Item | Per year |
|---|---|
| Salary | £41,700 |
| Income tax: 20% of (£41,700 − £12,570) | £5,826 |
| National Insurance: 8% of (£41,700 − £12,570) | £2,330 |
| Take-home pay | £33,544 (≈ £2,795 a month) |
Getting a National Insurance Number
You don't need to wait for a National Insurance (NI) number before you start work. GOV.UK says you can start work before you receive one if you can prove you have the right to work in the UK, though you must apply for one if you plan to work, and you can only apply once you're in the UK. To apply you need the right to work, plus either a job, an offer or an active job search. If you have a biometric residence permit or an eVisa, you might already have a number. Apply through GOV.UK directly, and be wary of anyone offering to do it for you for a fee.
Your First Payslip: Why Emergency Tax Happens
A missing NI number isn't what causes unexpectedly high tax on a first payslip. GOV.UK explains that you may be put on an emergency tax code (one ending in W1, M1 or X, such as 1257L M1) if HMRC doesn't get your income details in time after a change such as starting a new job. The fix is to give your employer a P45 from a previous job or, if you don't have one, to complete the HMRC starter checklist before your first payday. The checklist asks which of three statements applies to you, so read them carefully and choose the one that matches your real situation.
Here is what it can mean in cash (an illustration, using the GOV.UK 2026/27 rates). Suppose you start in October on £3,000 a month. On an emergency month-1 code, each payslip is taxed as if it were the first of the year with only one month's allowance (£1,048), so tax on that first £3,000 would be about £390. On a normal cumulative code, where nothing else has been earned since 6 April and by month 7 you've built up about £7,333 of tax-free pay, the same payslip would carry no tax at all. Emergency codes are temporary: GOV.UK says HMRC should move you to a normal code in the new tax year, and HMRC's own guidance says you can check and claim a refund online, in the HMRC app, or by cheque.
Income Tax and National Insurance
Both are deducted from your salary through PAYE. For 2026/27 in England, Wales and Northern Ireland, the Personal Allowance is £12,570, then 20% up to £37,700 of taxable income, 40% above that and 45% above £125,140; Scotland has its own income tax bands (see GOV.UK's rates page). Employee National Insurance is 8% on earnings between £12,570 and £50,270. As a worked example using the ONS median full-time salary of £39,039, Income Tax is about £5,294 and National Insurance about £2,118 (the method the Treasury uses for a median earner). That's £7,411, an effective rate of about 19%, leaving roughly £31,628 a year or £2,636 a month. Try your own figures in the UK Take-Home Pay Calculator, and see our UK salary guide for how that median compares with visa salary thresholds.
Planning for several years matters here, because the government extended the freeze on income tax thresholds in the November 2025 Budget. The Personal Allowance and higher-rate threshold are now frozen until April 2031, not April 2028 as earlier plans had it (see the House of Commons Library briefing). Because thresholds don't rise with wages, each pay rise pushes a larger share of your income into tax, so your effective rate will likely creep up even without a rate change. This is often called fiscal drag.
The Immigration Health Surcharge (IHS)
Most work and study visa applicants pay the IHS upfront as part of the visa application: £1,035 per adult per year, and £776 per year for students, Youth Mobility Scheme applicants and under-18s, as of mid-2026 (one law-firm summary; confirm the live rate on GOV.UK before paying). It's charged for each year of your visa, so a five-year Skilled Worker visa costs £5,175 per adult, and each adult dependant pays the same again. In return you get NHS access on broadly the same basis as a UK resident. Health and Care Worker visa holders and their dependants are exempt, but only if the application is made under that route; see our healthcare visa page and NHS Employers for how that works.
Tax Residency and Your Foreign Income
Whether you're taxed in the UK on your worldwide income depends on UK tax residency, which is decided by the Statutory Residence Test (based on days spent in the UK and your ties to it), not simply by having a visa. The UK tax year runs from 6 April to 5 April. If you arrive part-way through a year, split-year treatment can divide it into a UK part and an overseas part when you meet one of its conditions, so check before assuming you're taxed for the whole year.
Foreign income is where the rules changed most recently. From 6 April 2025 the old non-domicile remittance basis was abolished. In its place, a 4-year foreign income and gains (FIG) regime gives qualifying new residents relief from UK tax on most foreign income and gains for their first four tax years of UK residence. It's aimed at people who become UK resident after at least 10 consecutive tax years of non-residence, residence is decided by the Statutory Residence Test, and a split year counts as a full year toward the four (HM Treasury and HMRC technical note). Claiming it isn't free of trade-offs: as Deloitte notes, you lose the income tax personal allowance (where available), so it only pays off where your foreign income is large enough. Advice written before April 2025 about the remittance basis no longer applies, so get tax advice before you arrive if you have significant income or investments abroad.
Council Tax
On top of income tax, every household pays Council Tax to its local authority, which funds local services. It's billed by your council based on your property's valuation band, not deducted from your salary, and it varies widely by area, so it's a cost newcomers often forget when budgeting from salary alone. Use the Council Tax Calculator for your band and area, and see our housing guide for rents.
Where Newcomers' Tax Plans Go Wrong
- Waiting for an NI number before starting work. You can start work if you can prove your right to work, then apply once you're in the UK.
- Not giving your employer a P45 or starter checklist. That's what leads to an emergency code and an over-deducted first payslip.
- Assuming the health surcharge exemption follows the employer. It depends on the route your visa is granted under.
- Assuming "I moved here" settles your tax residency. The Statutory Residence Test and split-year rules decide it.
- Using pre-2025 non-dom advice for foreign income. The remittance basis was abolished in April 2025.
- Planning on thresholds thawing in 2028. They're now frozen until April 2031.
- Leaving Council Tax out of the budget. It's separate from rent and from income tax.
Frequently Asked Questions
Do I need a National Insurance number to work in the UK?
No. GOV.UK says you can start work before you receive one if you can prove your right to work. You must apply if you plan to work, and you can only apply once you're in the UK.
What is the Immigration Health Surcharge?
An upfront annual charge paid with most work and study visa applications: £1,035 per adult per year, and £776 for students, Youth Mobility Scheme applicants and under-18s as of mid-2026. Health and Care Worker visa holders are exempt if their application is made under that route.
Is Council Tax separate from income tax?
Yes. Income tax and National Insurance are deducted from your salary through PAYE; Council Tax is billed directly by your local authority based on your property's valuation band.
Why was so much tax taken from my first UK payslip?
You were probably put on an emergency tax code (ending W1, M1 or X) because your employer didn't have a P45 or completed starter checklist in time. It's temporary: give your employer the right details and any overpaid tax can be corrected or claimed back.
How long are UK income tax thresholds frozen for?
Until April 2031. The November 2025 Budget extended the freeze on the Personal Allowance and higher-rate threshold by three years beyond the earlier April 2028 date.
Is my foreign income taxed in the UK?
Once you're UK tax resident, foreign income can be taxable, but since 6 April 2025 qualifying new arrivals (generally those who were non-resident for at least 10 consecutive tax years) can claim a 4-year foreign income and gains regime that exempts most of it. Claiming it means losing the personal allowance, so take advice.
