How to read your payslip

Last reviewed

A sample payslip

Here’s a payslip for someone on £36,000 a year, paid monthly, with a 5% workplace pension and a Plan 2 student loan. The numbers match the sections below.

A sample payslip £36,000 a year, paid monthly, England (2026/27)

4 Deductions
Income Tax (PAYE) -£360.50

Student loan -£49.61
Pension (5%) -£150.00

An example only: your employer's layout and names will differ. The numbers match the sections of this guide.

1. Your tax code

Your tax code tells your employer how much you can earn tax-free. 1257L is the most common: £12,570 a year, or £1,047.50 a month. Codes ending in M1 or W1, or the letters X, mean an emergency code. See UK tax codes explained for what yours means.

2. Your National Insurance letter

The letter shows which NI rates apply. A is the standard letter for most employees. Others include C for people over State Pension age (no employee NI) and M for under-21s, where your employer pays less NI but you pay the same.

3. Payments

Your gross pay for the period: salary or hours worked, plus any overtime, bonus, holiday pay or sick pay. Here it’s £3,000, a twelfth of £36,000.

4. Deductions

Deduction How it’s worked out In the example
Income Tax (PAYE) 20% on pay above your tax-free amount, after a net pay pension £360.50
National Insurance 8% on pay between £12,570 and £50,270 a year, 2% above £156.20
Pension Your contribution, here 5% of your pay £150.00
Student loan 9% of pay over your plan’s threshold (£29,385 a year on Plan 2) £49.61

A few things that surprise people:

  • Income Tax is worked out on the year so far, so a big month followed by a small one evens out. National Insurance isn’t: it’s worked out on each payslip on its own.
  • How your pension shows depends on your scheme. Under net pay, it comes off before tax. Under relief at source, it comes off after tax and the provider adds 20%. Under salary sacrifice, your gross pay is simply lower.
  • Student loan repayments are worked out on each pay period too, so a month with overtime can mean a repayment even if your yearly pay is under the threshold.

5. Net pay

What’s left after deductions: £2,283.69 in the example. This is what should reach your bank account.

A real payslip can differ from these figures by a few pence. Payroll software uses HMRC’s monthly thresholds (£1,048 for National Insurance), and student loan deductions are rounded down to the whole pound.

Year-to-date figures and forms

Most payslips also show your pay and deductions so far this tax year, which starts on 6 April. October is month 7. At the end of the tax year you get a P60 with the year’s totals, and if you leave a job, a P45. Keep both: you’ll need them if you file a tax return or apply for a mortgage.

What to check each time

  • The tax code and NI letter look right, and your National Insurance number is correct.
  • Your gross pay matches your contract, including overtime.
  • The pension percentage is what you chose.
  • Any student loan plan is the right one.

If something looks wrong, ask your payroll team first. For a wrong tax code, contact HMRC.

Frequently asked questions

What does 1257L mean on my payslip?

It’s the most common tax code. It means you get the standard £12,570 Personal Allowance, so roughly the first £1,047.50 of each month’s pay is tax-free. A code with W1, M1 or X at the end is an emergency code.

What is the difference between gross pay and net pay?

Gross pay is what you earn before anything is taken off. Net pay is what reaches your bank account after Income Tax, National Insurance, your pension and any student loan or other deductions.

Why is my take-home pay different this month?

Common reasons are overtime or a bonus, a new tax code, a pay rise, sick pay, or a student loan repayment in a month with higher pay. National Insurance and student loans are worked out on each payslip on its own, so a big month can change them.

What should I do if my payslip looks wrong?

Ask your payroll or HR team first: most mistakes are fixed in the next pay run. If your tax code is wrong, check it in your personal tax account or the HMRC app and update your details with HMRC.

Do I have a right to a payslip?

Yes. Every employee and worker must get a payslip, on paper or online, on or before payday. If your hours vary, it must show the hours you’re paid for.
