Student Tax 2026/27

Most students in the UK pay no income tax at all, because part-time and summer earnings rarely reach the £12,570 personal allowance. The catch is that employers sometimes apply emergency tax codes — 1257L W1 or M1 — which deduct tax before your real allowance is known, and the refund only arrives if you ask for it. Getting the basics right can save you hundreds of pounds a year. Work out your take-home pay from term-time or summer work with the Student Tax Calculator→ and the Salary Calculator→.

This guide covers the personal allowance, emergency tax, summer job maths, savings interest, National Insurance and student loan deductions for 2026/27.

The Personal Allowance and Bands

Emma works 12 hours a week in a café and earns £6,000 over the tax year. Her earnings sit entirely inside the personal allowance, so income tax is £0. She also pays no National Insurance, because the NI primary threshold is the same £12,570. The most important practical point: your allowance is spread across the year through your tax code, so a summer job that pays £400 a week in July is taxed as if you would earn that all year — until the correct cumulative code is applied and the earlier tax is refunded through later payslips.

Emergency Tax — Why Students Get It and How to Fix It

Employers apply an emergency code when you start without a P45, or when HMRC has not yet matched your employment. On 1257L W1 (weekly) or 1257L M1 (monthly), tax is calculated on that pay period alone — one-fifty-second or one-twelfth of the allowance — with no look-back to earlier earnings. That is fine if your pay is steady, but it overtaxes lumpy, seasonal income.

Tom works a 10-week summer internship at £300 a week. On the emergency code each week's allowance is £241.73, so £58.27 is taxed at 20% — £11.65 a week, £116.54 in total — even though his £3,000 of annual earnings are far below the £12,570 allowance.

To fix it: give your employer your P45, or update your estimated earnings in your Personal Tax Account or the HMRC app. HMRC issues a corrected cumulative code and the overpaid tax is refunded through your payslip — or as a lump sum after the tax year ends. On a normal cumulative code the same £3,000 summer income produces £0 tax, because the running allowance always exceeds the running pay. Keep every P45 and P60; the P45 stops your next employer putting you back on emergency tax.

Savings Interest and the Starting Rate

Students often hold savings from birthdays, family gifts or summer work, and the interest is protected by three stacked allowances. The starting rate for savings taxes up to £5,000 of interest at 0% when your other income is within the personal allowance — and it reduces by £1 for every £1 of other income above £12,570, disappearing once other income passes £17,570. On top of that, the personal savings allowance makes £1,000 of interest tax-free for basic-rate taxpayers and £500 for higher-rate taxpayers.

Olivia earns £6,000 from a part-time job and £3,000 of interest. The personal allowance covers her job income, and the starting rate covers all £3,000 of interest at 0% — total tax £0. Even James, with no job and £6,500 of interest, pays nothing: his personal allowance can be set against savings interest when he has no other income. The combination of the personal allowance, starting rate and PSA means almost every student pays zero tax on savings.

National Insurance for Students

NI is separate from income tax and works per employment. In 2026/27 you pay 8% on earnings between the £12,570 primary threshold and the £50,270 upper threshold, then 2% above — so a part-time job at £6,000 or a £3,000 internship pays no NI at all. The trap is multiple jobs: each employer applies the thresholds separately, so two jobs at £8,000 each both escape NI while your combined £16,000 exceeds the threshold. Self-employed students only pay Class 4 on profits above the small profits threshold, so most tutoring income escapes entirely.

Student Loans and Filing a Return

Student loan deductions sit on your payslip next to tax but are a separate debt. For 2026/27, the annual thresholds are £26,900 for Plan 1, £29,385 for Plan 2, £33,795 for Plan 4, £25,000 for Plan 5 and £21,000 for Postgraduate Loans; the repayment rates are 9% for Plans 1, 2, 4 and 5 and 6% for a Postgraduate Loan. A graduate earning £28,000 on Plan 2 is below that plan's annual threshold, so no Plan 2 deduction is due on an annualised calculation. Most students never file a Self Assessment return: PAYE handles employment income, but self-employment, untaxed income, gains and an HMRC notice can create separate filing or reporting obligations.

The Yearly Rhythm

The tax year runs 6 April to 5 April, so summer work in June–September and term-time shifts in the following spring can fall in different tax years — each with its own £12,570 allowance. If you earn £8,000 one year and £9,000 the next, both are tax-free; only income above the allowance within a single year is taxed. If you overpaid because of an emergency code, reclaim after the year ends, and check your P60 before contacting HMRC so you have the figures to hand.

Working from Home as a Student

Students who work remotely — online tutoring, freelancing, content creation — can claim work-related costs against their earnings. Employees cannot claim the working-from-home tax relief for 2026/27, although claims for eligible earlier years remain possible; self-employed students choose between the £1,000 trading allowance and actual expenses. A student tutor earning £1,200 with £300 of allowable business costs can compare the trading allowance with actual expenses, but must not claim both for the same income. The wholly-and-exclusively rule still applies to self-employed costs and mixed household use must be apportioned.

Frequently Asked Questions

Evidence and decision checks

A reliable student tax 2026 27 review starts by fixing the tax year and the date on which the relevant event happened. Record the person's or business's status, the income or transaction category, the amount before tax, tax already withheld, and any election or claim being relied on. Do not combine a headline figure with a final liability: the result can change when another income source, a payment date, an ownership interest or a qualifying condition is added.

Keep the source documents behind every important input. Depending on the subject, that may include payslips, invoices, bank statements, contracts, provider statements, travel records, HMRC notices, payroll submissions, valuations or correspondence. Where an amount is apportioned, write down the method and retain the underlying total. If a correction is made, preserve the original figure and explain the reason, date and evidence for the replacement.

Before relying on the result, check the current official guidance for the same tax year and jurisdiction. Distinguish enacted law from a consultation, draft measure, announcement or future proposal, and record the effective date. Reconcile the final estimate to the relevant return, payroll record or HMRC account. A calculator or explanatory guide can support a decision, but it cannot replace the eligibility test or the official filing and payment process.
