How to Read Your Payslip in the UK: A Student-Friendly Guide
First jobs and part-time shifts often come with payslips that feel like code. Once you know what each line means, you can spot errors, claim refunds if you overpay, and budget with confidence. Use this guide to decode your payslip, from tax codes and National Insurance to student loan deductions and year-to-date totals.
What a payslip must show
UK payslips vary in layout, but legally they must include:
- Gross pay (before deductions)
- Variable deductions such as Income Tax and National Insurance
- Fixed deductions, if any, and what they are for
- Net pay (what lands in your account)
- The pay period and payment method
Most also show employer details, your name, NI number, and a breakdown of hours if you are paid by the hour.
The top section: identity and period
- Employee name and NI number. Check spelling and the correct NI number.
- Payroll number. Your internal reference with the employer.
- Pay date and pay period. For example, Month 5 or Week 18 of the tax year.
- Tax code. Tells payroll how much of your income is tax-free across the year. New starters often see temporary codes until HMRC updates records.
Pay lines: gross, taxable, and net
- Basic pay / hours. Your contracted hours or hourly rate multiplied by hours worked.
- Overtime / enhancements. Separate lines for overtime or night rates.
- Holiday pay. Often appears when you take paid leave or receive rolled-up holiday pay for casual work.
- Gross pay. Total before deductions.
- Taxable pay this period. The amount used to calculate Income Tax after any pre-tax adjustments.
- Net pay. What arrives in your bank.
Statutory deductions you will usually see
- Income Tax (PAYE). Calculated on your taxable pay using your tax code and cumulative earnings.
- National Insurance (NI). Calculated each pay period when your pay crosses the NI threshold.
- Student Loan. Deductions begin only when your pay exceeds your plan’s threshold.
- Postgraduate Loan (PGL). Separate line if applicable.
You may also see pension contributions, apprenticeship levy (employer only), and attachment orders if any court-ordered deductions exist.
Understanding tax codes
Common patterns:
- 1257L (or similar). A standard personal allowance spread across the year.
- BR. Basic rate on all pay from that job. Often used for a second job until HMRC reallocates allowances.
- D0 / D1. Higher or additional rate applied to all pay in that job.
- W1 / M1. Week 1 or Month 1 emergency markers. Treats each period in isolation, which can over-deduct or under-deduct until corrected.
If your code looks wrong or temporary, contact HMRC via your Personal Tax Account and your employer’s payroll.
National Insurance category letters
- A. Most employees.
- M / Z. Under-21 or apprentice categories.
- C. Over State Pension age (no employee NI).
Your payslip shows the NI Category used to calculate contributions for the period.
Student loan markers
Your payslip may show:
- Student Loan Plan 1 / 2 / 4 / 5 and a separate line for Postgrad Loan if applicable.
- Deductions appear only when your period earnings exceed the plan threshold. If you believe deductions started in error, contact the Student Loans Company to check your plan status.
Pension contributions
Auto-enrolment shows as:
- Employee pension (your contribution)
- Employer pension (employer’s contribution)
Some schemes deduct before tax (relief at source vs net pay arrangement). The payslip or scheme documents explain which method is used.
Year-to-date (YTD) totals
Look for YTD columns for:
- Gross pay to date
- Tax to date
- NI to date
- Student loan to date
These help you check cumulative calculations, claim refunds if needed, and reconcile with your P60 at year end.
Other items you might see
- Expenses or mileage. Reimbursed amounts should not usually be taxed if they meet HMRC rules.
- Benefits in kind. Some are taxed via your code; others appear on a P11D after the year.
- Sick or parental pay. Labeled SSP, SMP, etc., with statutory rates shown for qualifying periods.
Quick example (illustrative)
- Gross pay: £920
- Taxable pay this period: £920
- PAYE Income Tax: £18
- NI (Category A): £24
- Student Loan Plan 2: £0 (below threshold this month)
- Employee pension: £20
- Net pay: £858
YTD columns show running totals since 6 April.
Common errors to watch for
- Wrong tax code after a job change or when you have two jobs
- NI category incorrect for your age or status
- Student loan deducted on the wrong plan or before you should be in repayment
- Overtime rate miscalculated or hours recorded incorrectly
- Holiday pay missing for accrued leave on casual contracts
Raise issues with payroll promptly and keep copies of contracts, rotas, and timesheets.
Documents to keep each year
- Payslips for each period
- P60 from your employer after 5 April (summary of the year)
- P45 when you leave a job (hand to your next employer)
- Student loan statements and your online HMRC Personal Tax Account snapshots
What to do if you think you overpaid tax
- Check your YTD pay and tax against your expected annual income.
- If you left a job and will not work again this tax year, claim an in-year refund using the HMRC process.
- Otherwise, HMRC usually reconciles after the tax year and issues a refund where due.
Simple checklist each payday
- Name, NI number, and pay period are correct
- Hours, rate, and overtime match your records
- Tax code and NI category look right
- Student loan lines match your plan status
- Net pay matches the bank credit
- File the payslip where you can find it later
Understanding your payslip is one of the quickest finance wins at uni. Five minutes each payday protects you from errors, helps you plan cash flow, and makes tax time easy. Keep your documents, fix problems early, and use the YTD totals to stay on top of your real earnings for the year.
