Read Your Payslip Like a Payroll Officer: Every Line Explained

Most of us check one number on payday: what landed in the bank. A payroll officer reads the whole payslip, because every line tells you how that number was reached.

A wrong tax code, a missing overtime payment or a pension deduction you didn’t expect can all sit quietly on the page. Once you know what each line means, you can spot them yourself.

Let’s walk through a sample payslip, line by line.

This payslip is for a made-up employee in England who earns £3,000 a month, with no student loan. It uses 2026/27 rates. Layouts differ between employers, but the same information should be there.

Gross pay

Gross pay is what you earned before anything is taken off. Here, it is £2,800 basic pay plus £200 overtime. If you are paid by the hour, your payslip must show the hours you worked, so compare them with your own record.

Tax code

Your tax code tells your employer how much you can earn tax-free. 1257L is the usual code for people with one job or pension. Add a zero to 1257 and you get roughly the £12,570 standard Personal Allowance. The L means you get that standard allowance.

These are worth noticing:

Code	What it usually means
M	You received part of your partner’s allowance through Marriage Allowance
N	You gave part of your allowance to your partner
T	HMRC needs extra calculations to work out your allowance
BR	All income from this job is taxed at the basic rate
D0	All income from this job is taxed at the higher rate
0T	No tax-free allowance is being used for this job
W1, M1 or X at the end	A temporary emergency code

A new job is a common time to see an emergency code. If yours looks wrong, ask your payroll team or check with HMRC.

Employee pension

If you are auto-enrolled, the usual legal minimum is 8% in total, with at least 3% from your employer and 5% from you. In 2026/27, the minimum is commonly worked out on earnings between £6,240 and £50,270 a year, or £520 to about £4,189 a month.

Our employee pays 5% of £2,480 (£3,000 minus £520), which is £124.00. In this example, the pension comes out before Income Tax. Some schemes work differently, and some employers use your full pay instead.

Income Tax

Think of your pay as a jar with a tax-free layer at the bottom. In 2026/27, that layer is about £1,048 a month for someone on 1257L. Most of the rest is taxed at the basic rate of 20%.

• Start with £3,000.
• Take off the £124 pension, leaving £2,876.
• Take off the £1,048 tax-free amount, leaving £1,828.
• Multiply £1,828 by 20%, which gives £365.60.

Payroll software may differ by a few pence because it uses exact tax tables. Scotland has its own Income Tax rates, so a Scottish payslip will look different.

National Insurance

The letter A is the most common National Insurance category for employees. In 2026/27, category A employees pay 8% on monthly earnings between £1,048 and £4,189, then 2% on anything above that.

Our employee pays 8% of £1,952 (£3,000 minus £1,048), which is £156.16. It is worked out on gross pay here, so the pension doesn’t reduce it.

Net pay

Net pay, or take-home pay, is what reaches your bank account. Here, £3,000.00 minus £645.76 leaves £2,354.24.

Year-to-date figures

These totals run from 6 April, the start of the tax year. They help you see whether one month is out of line with the rest. Month 7 is the tax month from 6 October to 5 November.

Lines you may also see

• Student loan: On Plan 2, you repay 9% of earnings above £2,448.75 a month.
• Statutory pay: Payments such as Statutory Sick Pay or Statutory Maternity Pay.
• Other deductions: Regular deductions, such as a season ticket loan, must be explained on the payslip or in a separate statement.

What your employer pays on top

The real cost of employing someone is higher than gross pay. Using the minimum 3%, our employer adds £74.40 to the pension. Employer National Insurance adds £387.45, at 15% above £417 a month. Together, that brings the monthly cost to £3,461.85.

• Is your name and National Insurance number correct?
• Has your tax code changed since last month?
• Do your hours and overtime match what you worked?
• Does your pension deduction look the same as usual?
• Does the net pay match what reached your bank?

Keep your payslips too. They can be evidence of your earnings, tax paid and pension contributions.
