Quick answer
Most part-time student workers in the UK pay no income tax because they earn less than the £12,570 personal allowance per year. Employed workers are taxed automatically through PAYE — your employer deducts whatever is owed. National Insurance kicks in separately, from around £242 a week. If you're self-employed and earn more than £1,000, you'll need to file a self-assessment return.
Does working as a student mean paying tax in the UK?
The UK tax system applies to everyone who earns money here — international students included. The same rules apply to you as to any UK resident, regardless of your visa type.
The good news: most part-time student workers earn below the personal allowance (£12,570 in 2024/25), so they pay no income tax at all. Tax only applies on earnings above that threshold.
The UK tax year runs from 6 April to 5 April the following year. Every threshold resets on 6 April.
How PAYE works for employed students
If you work for an employer (a café, a university department, a retail shop), your income tax and National Insurance are handled through PAYE (Pay As You Earn). Your employer calculates what you owe each pay period and deducts it before you receive your wages.
You do not need to file a tax return just because you work part-time.
Starting a new job
When you start, your employer will ask you to fill in a starter checklist. Answer the question about whether this is your only job accurately. If you tick the wrong box, you may be put on an emergency tax code (1257L W1 or M1), which deducts more tax than necessary.
If you were overtaxed
Sometimes too much is deducted, particularly if you worked for only part of the tax year or had a gap in employment. HMRC usually corrects this automatically after 5 April, but you can claim earlier via your personal tax account. When you leave a job, your employer gives you a P45 — keep it safe. You'll need it for your next employer, and it helps HMRC calculate any refund.
National Insurance: the separate deduction
Income tax and National Insurance (NI) are two separate things, even though both appear on your payslip.
NI funds the NHS and the state pension. Employees pay NI at 8% on weekly earnings between £242 and £967. Below £242 in a week, no NI is deducted. Above £967, the rate falls to 2%.
NI is calculated per pay period (weekly or monthly), not annually. So if you earn £100 one week and £350 the next, NI is only deducted in the week you exceed £242.

If you're self-employed
Self-employment covers freelance tutoring, translation work, selling items online, babysitting, or any work where you invoice rather than receive a payslip.
If your self-employed profit (income minus allowable expenses) exceeds £1,000 in a tax year, you must register for self-assessment and file a tax return. Under £1,000, the trading allowance covers you — no registration required.
Self-assessment returns are due by 31 January following the end of the tax year. Miss the deadline and HMRC charges an automatic £100 late-filing penalty.

A note for student visa holders: standard student visas permit employed part-time work during term time, but self-employment is restricted. Check your visa conditions carefully before taking on freelance or gig work. The working while studying guide covers what you can and cannot do.
Your National Insurance number
You'll need a National Insurance (NI) number before your second pay run at the latest. Apply online at gov.uk/apply-national-insurance-number — you'll need your eVisa or BRP and proof of UK address.
You can start work while waiting for your NI number, but give your employer the number as soon as it arrives. If you haven't applied yet, the national insurance guide on Luodi walks through the process step by step.
Working hours and your visa
This is a tax guide, not a visa guide — but it's worth stating clearly: student visas limit you to 20 hours a week during term time. Exceeding this is a visa breach, regardless of how much tax you pay. There are no hour restrictions during official university holidays.
FAQ
Do international students pay UK income tax?
Yes, on the same rules as everyone else. If your total UK earnings in the tax year exceed £12,570, you'll pay 20% on the excess up to £50,270. Under £12,570, you owe nothing.
What if I work two jobs at the same time?
Only one employer can apply your full personal allowance. If you have two jobs simultaneously, tell your second employer — they'll usually tax you at 20% (basic rate) on everything you earn with them. You can ask HMRC to split the allowance between both employers via your personal tax account.
Do I need to tell HMRC I'm an international student?
No. HMRC doesn't track visa status. Your income is taxed the same way as any UK resident's. You don't need to register with HMRC unless you're self-employed or your income is above certain thresholds.
Can I claim back tax deducted during the year?
Yes. If you worked for only part of the tax year (say, October to June), you'll have used only part of your personal allowance. HMRC usually issues a refund automatically after 5 April — often directly into your bank account. If you want to claim earlier, use your personal tax account at gov.uk.
What is an NI number and do I need one to work?
Your National Insurance number (format: AB 12 34 56 C) is your permanent reference in the UK tax and benefits system. You can technically start work before you have one, but your employer needs it to pay your tax and NI correctly. Apply as soon as you arrive.
