Student summer job tax explained: why tax comes off your summer wages, whether you should pay it, and how to claim it back in the 2026/27 tax year.
Your first proper payslip is a strange thing to read. You worked the hours, the number at the bottom is smaller than the hours times the rate, and somewhere in the middle a line called “PAYE” or “tax” has taken a slice. If you’re a student who just picked up summer work, that slice is probably coming back to you.
Here’s what student summer job tax actually is, whether you should be paying it, and how to get it back if you shouldn’t.
Students are taxed exactly like every other worker, so tax can come off your summer wages, but if you earn under £12,570 across the whole tax year you shouldn’t owe any income tax, and can reclaim whatever was deducted.
There’s a myth that students are tax-exempt. They aren’t, and haven’t been since 2013 when HMRC scrapped the old P38(S) student form. What’s true is that most students earn under the personal allowance, so they end up owing nothing, even if the payslip took tax at the time.
Your personal allowance for 2026/27 is £12,570. That’s the amount you can earn in the tax year (6 April to 5 April) before any income tax is due. It’s frozen at that level until at least April 2028.
The problem is timing. PAYE, the system your employer uses, doesn’t know in July that you’ll only work eight weeks. When you start a job with no P45 from a previous employer, payroll often puts you on an emergency tax code. An emergency code frequently taxes each pay period on its own, as if that week or month repeated all year, instead of spreading your full allowance across the twelve months.
So a busy summer week can look, to payroll, like a high annual salary, and it deducts income tax accordingly. That’s the source of most student summer job tax. It isn’t a mistake exactly, it’s the system being cautious, and it corrects later.
Say you work eight weeks over the summer at £375 a week, earning £3,000 in total, and you won’t work again before the tax year ends.
Your total income for the year is £3,000, well under the £12,570 allowance. Your correct income tax bill is zero.
But on an emergency 1257L W1 code, payroll gives you one week’s worth of allowance at a time, roughly £242 a week. So each week it treats £133 as taxable and charges 20%, about £26.65 a week. Over eight weeks that’s around £213 of income tax deducted, all of which you’re owed back.
National Insurance is a different story, and this is the part students get caught out by.
National Insurance is worked out per pay period, not across the year. For 2026/27, employee National Insurance is 8% on weekly earnings between £242 and £967.
In the example above, £375 a week is £133 over the £242 threshold, so 8% of £133, about £10.64, comes off each week. Across eight weeks that’s roughly £85 of National Insurance.
Unlike income tax, that £85 is not refundable. It doesn’t matter that your annual earnings stayed under the personal allowance. National Insurance looks only at the individual week, and once it’s paid on a week where you earned over the threshold, it stays paid. Worth knowing before you count on getting everything back.
Two quick checks tell you whether you’ve overpaid.
First, find your tax code. It’s on your payslip, and in the HMRC app (free on iOS and Android) once you’ve signed in with a Government Gateway ID. If it ends in W1, M1, or you see 0T or BR, you’re on an emergency or non-standard code and have likely overpaid income tax.
Second, add up what you’ll earn for the whole tax year, across every job. If the total is under £12,570, you shouldn’t owe any income tax at all, so anything in the tax line on your payslips is refundable.
When you start a job, filling in the HMRC starter checklist honestly helps a lot. If you tick statement A, that this is your first job since 6 April and you’ve had no other taxable income, payroll can often put you straight onto a cumulative 1257L code, which spreads your allowance properly and takes little or no tax in the first place.
You’ve got two routes, depending on whether you’re finished working for the year.
If you’ve stopped working and won’t earn again before 5 April, you don’t have to wait. Use form P50 through your Personal Tax Account to claim the refund now. This is the classic student move: finish the summer job, head back to university, claim the overpaid tax before term even starts. HMRC processes P50 refunds within a few weeks.
If you’re going to keep working, whether that’s a term-time job or another gig, leave it. HMRC reconciles your tax automatically after the tax year ends on 5 April. If you overpaid, they send a P800 calculation and refund the difference, usually straight to your bank account.
Either way, check the HMRC app first so you know the number you’re chasing. If you want to read the detail on emergency codes and the fastest refund route, our guide on how to claim emergency tax back walks through it step by step.
Most student summer job tax problems trace back to one form you fill in on day one: the starter checklist. Get it right and you often avoid an emergency code entirely.
The checklist asks you to pick a statement about your situation. Statement A means this is your first job since 6 April and you’ve had no other taxable income or benefits since then. For a lot of students, especially anyone doing their first-ever summer job, that’s exactly true, and ticking it lets payroll put you on a cumulative 1257L that spreads your allowance properly from the start.
Statement B is for when you’ve had another job earlier in the tax year but don’t have a P45 for it. Statement C is for when you’ve got another job running alongside this one. Both of those push you onto more cautious codes, which is right if they apply, but a lot of students tick B or C by accident when A was the honest answer, and end up overtaxed for no reason.
If you filled it in wrongly, it’s fixable. Tell your employer, or update your details in the HMRC app, and the code corrects.
One summer job, then back to studying. This is the classic refund case. You earn under the allowance, tax comes off on an emergency code, and you claim it back with P50 once term starts. Straightforward money owed to you.
A summer job plus a term-time job. Here you might genuinely have two jobs at once, so a BR code on the second one can be correct. Add up the total across both. If the combined figure stays under £12,570, you’re still owed any tax deducted, it just gets sorted at year-end rather than with an early P50.
An apprenticeship or placement. These usually run all year, so you’re taxed like any other employee on a cumulative code, and if your annual pay is over £12,570 you’ll owe some tax and keep it. That’s normal, not an error.
Nothing about the underlying rules changed for the 2026/27 tax year. The personal allowance is still £12,570, there’s still no student exemption, and emergency codes still work the same cautious way.
What did change, from April 2026, is that HMRC moved most tax code notices online. If your code updates partway through your summer job, you’ll usually see it in your HMRC account rather than getting a letter. And with the National Living Wage now £12.71 an hour, and £10.85 for 18 to 20 year-olds, students are hitting the National Insurance threshold in fewer hours than before, so it’s more common to see deductions on a summer payslip than it used to be.

Students pay tax exactly like everyone else. There is no special student exemption, and hasn't been since the old P38(S) form was scrapped in 2013. You only owe income tax if your total earnings for the year go over the £12,570 personal allowance. Most summer-only jobs stay under that, so any tax deducted is usually refundable.
Usually because you started with no P45, so payroll put you on an emergency tax code. An emergency code often taxes each week or month in isolation, without spreading your full personal allowance across the year. That can deduct income tax even though you'll earn under £12,570 for the year and owe nothing.
If you stop working before the tax year ends and won't earn again that year, you can claim a refund straight away with form P50 through your Personal Tax Account. If you keep working, HMRC reconciles automatically after 5 April and refunds any overpayment. You can also check and claim in the HMRC app.
No. National Insurance is worked out per pay period, not per year, and isn't refunded even if your annual earnings stay under the personal allowance. If you earned over £242 in any single week, some National Insurance came off and it stays paid. Only income tax is reconciled and refundable.
