Getting a part-time job is practically a university tradition. It might fund your food shop, cover a few nights out or simply stop your overdraft from looking quite so terrifying. Then your first payslip arrives and you notice deductions for tax or National Insurance. Surely students are not supposed to pay those, are they?
Unfortunately, being a student does not make you exempt from tax. Students are taxed under the same rules as everybody else. Whether anything is actually deducted depends on how much you earn, how often you are paid and whether HMRC has given your employer the correct information.
How Much Can a Student Earn Before Paying Income Tax?
Most people receive a tax-free Personal Allowance. For the 2026/27 tax year, which runs from 6 April 2026 to 5 April 2027, the standard Personal Allowance is £12,570. If your total taxable income remains below that figure, you will not normally owe any Income Tax.
It is your total income for the entire tax year that matters, not simply what you earn during term time. Pay from a summer job, Christmas shifts and work for more than one employer all counts towards the same allowance.
If you earn more than £12,570, you generally pay tax only on the portion above the allowance. In England, Wales and Northern Ireland, the basic Income Tax rate is 20%. Scotland has its own tax bands and rates, although the standard Personal Allowance is still £12,570.
Imagine you earned £13,570 across the tax year and had no other taxable income. The first £12,570 would be covered by your Personal Allowance, leaving £1,000 taxable. At the basic rate, that would mean £200 in Income Tax. You would not pay 20% on the full £13,570.
Your employer normally handles this through PAYE, which stands for Pay As You Earn. The tax is removed before your wages reach your bank account, so you do not usually need to calculate or send it yourself.
National Insurance Works Slightly Differently
Income Tax and National Insurance often appear together on a payslip, but they are not calculated in exactly the same way.
For most employees in 2026/27, National Insurance starts when earnings exceed £242 a week or £1,048 a month. The usual employee rate is 8% on earnings between £242 and £967 a week, with a 2% rate applying above that. Only the part of your pay above the relevant threshold is charged.
National Insurance is normally calculated for each pay period rather than from your final annual income. This can catch students out. You might earn less than £12,570 across the whole year but still pay National Insurance during a particularly busy week or month. For example, working many hours over Christmas could take that pay packet above the threshold even if your usual wages are much lower.
Why Have I Paid Tax When I Earn Less Than £12,570?
Paying tax on one payslip does not necessarily mean that you will owe tax for the whole year. PAYE estimates your position as the year progresses, and problems can arise when you start a new job without the right paperwork.
You may be placed on an emergency tax code if your employer does not have details of your previous income. Emergency codes commonly end in W1, M1 or X. Under one of these codes, your tax may be worked out using only that week’s or month’s pay, rather than your income across the year.
Give your new employer a P45 if you received one when leaving your previous job. If this is your first job or you do not have a P45, complete the starter checklist carefully. You can find your tax code on your payslip and check it through your HMRC online account.
Another common problem occurs when you have two jobs. HMRC will usually apply your Personal Allowance to one job, while the other may use a BR tax code and deduct basic-rate tax from all its pay. That could be correct if your first job uses your full allowance, but it can lead to an overpayment when your combined earnings are low. HMRC can review how your allowance is divided between the jobs.
If you have paid too much, the refund may arrive automatically through a later wage payment once your code is corrected. Students who stop working part-way through the tax year may also be able to claim a refund from HMRC. Keep your payslips and P45 because they show what you earned and what was deducted.
What About Freelancing and Side Hustles?
Not every student job comes with an employer and a payroll department. You might tutor privately, deliver freelance design work, create paid social media content or sell services online. A student side hustle, in other words. In that situation, tax is not normally deducted before you are paid, but the income can still be taxable.
If your gross trading income is more than £1,000 in a tax year, you will generally need to tell HMRC and may have to register for Self Assessment. The £1,000 figure relates to income before expenses, not profit. Earning cash rather than receiving a bank transfer does not make the work tax-free.
The rules can become more complicated if you have both an employed job and freelance income, so keep clear records of every payment and expense from the beginning.
Is a Student Loan Deduction the Same as Tax?
Student loan repayments are separate from Income Tax and National Insurance. For most full-time students, the earliest repayments begin is the April after leaving their course, and only when earnings exceed the threshold for their loan plan.
If repayments are due, an employer usually takes them from your wages alongside tax and National Insurance. The deduction should appear separately on your payslip. Receiving a maintenance loan while you study does not itself mean that tax will be taken from your part-time wages.
The simplest habit is to check every payslip. Look at your gross pay, tax code and each deduction rather than concentrating only on the amount that reaches your bank. If something looks wrong, speak to your employer’s payroll team and check your details with HMRC. Students can certainly pay tax on part-time jobs, but they should not pay more than the rules require.
