Working as a Student and Paying Tax

The first payslip is a small shock. The number at the bottom is lower than the pay you expected, and a column of abbreviations explains the difference: tax, National Insurance and perhaps something about your loan. For students in the UK, the reaction is often worry: am I being overcharged? Am I allowed to earn this much? Do I have to do anything? In most cases, the system works if you know a few basics, check a few things and keep your records.

UK tax rules change each year and depend on your situation. This guide describes the system in general terms, quotes no rates or thresholds and is not tax advice. Check the official government guidance for the current tax year, or speak to a qualified adviser.

The basics: tax and allowances

In the UK, most people can earn a certain amount each tax year before they pay income tax. This is called the personal allowance. Income above it is taxed at set rates. The tax year runs from early April to early April, not from January to December or by the academic calendar.

For students, this means:

• If your total income in the tax year is below the allowance, you may owe no income tax.
• If you work a part-time job during term and a full-time job in the summer, your annual total might still be low, but your employer may deduct tax each pay period as if you would earn the same all year.
• If you start work in the middle of a tax year, the allowance is usually spread across pay periods, which can lead to overpaying early and getting it back later.

The allowance can be affected by other income, such as interest or self-employment profit, and by other circumstances. Check the current rules.

Tax codes

Your employer uses a tax code from the tax authority to decide how much tax to deduct. The code reflects your allowance and any adjustments. If you do not have a code yet, the employer may use an emergency code, which can result in too much tax being deducted at first.

• Check your payslip or tax code notice to see your code.
• If the code looks wrong, contact the tax authority, which can issue a corrected one.
• If you have more than one job, your allowance is usually applied to one, and the other may be taxed from the first pound. Make sure the codes reflect your actual situation.
• If you start a job and have another source of income, tell the tax authority.

Starter paperwork

When you start a job, your employer needs information to set up payroll. They may ask for:

• Your National Insurance number. If you do not have one, you can apply for it.
• A starter checklist or statement about whether this is your first job, whether you have other jobs and whether you receive a student loan.
• A P45 from a previous employer, if you have one.
• Bank details.

Fill in the starter information carefully, because it affects your tax code and loan deductions.

Payslips and year-end documents

Your payslip should show:

• Gross pay, before deductions.
• Tax deducted, and your tax code.
• National Insurance contributions.
• Any pension contribution.
• Student loan deductions, if applicable.
• Net pay, what you receive.
• Year-to-date totals.

Keep payslips.

Other documents:

• P45: given when you leave a job, showing pay and tax so far in the tax year. Keep it, and give it to your next employer.
• P60: a summary at the end of the tax year if you were still working for the employer.
• P11D: for taxable benefits, if you receive any.

National Insurance

National Insurance contributions are payments that build your entitlement to certain state benefits, including the State Pension. Employees pay contributions if they earn above a threshold. Employers also pay. If you are self-employed, you may pay different classes of contributions.

• Students often earn below the threshold and pay nothing, but check your payslip.
• If you earn above it, deductions appear automatically.
• Gaps in your record can affect future benefits.

Student loan repayments

Repayment of UK student loans is linked to income and your plan type. Key points:

• You normally begin repaying only after you finish or leave your course and when your income is above the threshold for your plan.
• Repayments are taken through payroll by employers when you are employed, or through your self-assessment return if you are self-employed.
• If a deduction appears while you are still studying, check your starter statement and plan details. A mistake can happen.
• Different plan types have different thresholds.

If you believe you are being charged wrongly, contact your employer and the loan company. Our budgeting guides explain different forms of student debt.

Self-employment and gig work

If you work for yourself, you are responsible for reporting income to the tax authority.

• Register as self-employed if you earn above a small trading allowance, check current guidance.
• Keep records of income and costs.
• Complete a self-assessment tax return by the deadline.
• Pay tax and National Insurance as required, sometimes in advance installments.
• Remember that gig platforms may not deduct tax.

A trading allowance may let you earn a small amount tax-free without reporting it, but there are rules. Check what applies to you. Our guide to managing irregular income explains how to plan for tax on uneven earnings.

Getting a refund

If you have paid too much tax, you may be entitled to a refund.

1. Check your payslips and year-end documents. Compare the tax deducted with the tax owed on your total income.
2. Use the tax authority's online tools to check or claim a refund. Many refunds are processed online.
3. If you left a job and have a P45, you may be able to claim a refund if you did not work again that tax year.
4. Avoid companies that charge a large fee to claim a refund. You can often claim directly for free.
5. Keep evidence, such as payslips and the P45.

Refunds can take weeks. Do not rely on one for essential costs.

International students

International students in the UK may have visa conditions that restrict hours and types of work, and tax rules that depend on residence status for tax purposes.

• Check your visa conditions before accepting any job.
• Get a National Insurance number if you work.
• Understand whether you are a UK tax resident, which can affect your allowance and treatment of foreign income.
• Keep records of earnings and tax deducted.
• Ask your university's international team about tax workshops.

Our guide to budgeting as an international student covers other costs.

Planning for a summer job

Summer jobs often pay more per week than term-time jobs. Before you start, check your tax code and any student loan information on your starter checklist. Keep an eye on your total earnings for the tax year, including part-time work earlier in the year. If your employer deducts tax early in the year because you started late, plan to check for a refund after your last payslip.

Common mistakes

• Ignoring a wrong tax code.
• Failing to give starter information.
• Not keeping payslips or the P45.
• Missing self-assessment deadlines.
• Paying a company to claim a refund that you could get free.
• Working outside visa limits.
• Not setting aside money for tax on gig income.

A quick checklist

• Do I have a National Insurance number and a correct tax code?
• Have I kept payslips, my P45 and my P60?
• Do I know whether I must register or file as self-employed?
• Do I know if student loan deductions apply to me?
• Do I know how to claim a refund for free?

Final thoughts

Working as a student means a little paperwork and a few checks. Give your employer the right information, check your tax code, keep your records and claim back overpaid tax. If you work for yourself, report your income and plan for tax. Use official sources and free help, and the system will treat you fairly.
