PayBreakdown

Payslip explained: gross pay, net pay, tax, NI and deductions

A practical UK payslip guide covering gross pay, net pay, PAYE tax, National Insurance, pension, student loans, pay period and year-to-date totals.

The short answer

A payslip is easiest to read when you separate the pay coming in, the deductions going out, and the net pay left at the end. Gross pay starts the calculation, payroll deductions reduce it, and net pay is the amount paid for that period.

A worked example

On £35,000 a year, a standard 2026/27 tax code and no pension or student loan, the figures work out like this. Open a calculator to put your own numbers in.

Why a payslip can differ

Tax codeHMRC tax-code changes, K codes, BR/D codes, or emergency markers can change PAYE deductions.
Cumulative basisWeek 1, Month 1 or non-cumulative payroll can differ from a smooth annual calculator estimate.
Pension methodRelief at source, net pay and salary sacrifice can affect taxable pay and take-home pay differently.
Payroll timingBonus, overtime, arrears, refunds, cut-off dates and corrections can all move a single payslip.

The main sections

Most payslips group the same information even when the layout looks different. The wording can vary, but the calculation usually follows a gross-to-net pattern.

  • Gross pay: salary, hourly pay, overtime, bonus or commission before deductions.
  • Taxable pay: the pay figure payroll uses for PAYE Income Tax after the employer's pension and benefit treatment.
  • Deductions: Income Tax, employee National Insurance, pension, student loan, postgraduate loan and any employer-specific adjustments.
  • Net pay: the amount paid after deductions for the pay period.
  • Year-to-date figures: running totals for the tax year, often useful when comparing with a P60.

Why two payslips can look different

Two employees with the same headline salary can have different payslips because payroll is personal to tax code, pension method, loan plan, pay timing and employer scheme rules.

  • A salary sacrifice pension can reduce contractual or taxable pay in a different way from relief at source.
  • Student loan repayments depend on plan, pay period and income above the threshold.
  • A bonus or overtime payment can make one month look unusually high for deductions.
  • A tax-code change can alter PAYE without changing gross salary.

What to check before contacting payroll

A clear question is easier for payroll to answer. Compare the payslip fields before treating a single deduction as isolated.

  • Is the pay period correct?
  • Does the tax code match the latest HMRC notice or account view?
  • Does taxable pay match what you expected after pension or salary sacrifice?
  • Did the period include bonus, overtime, arrears, holiday pay or a correction?
  • Do year-to-date totals help explain whether this is a one-off or an ongoing pattern?

Frequently asked questions

Which payslip figure should I use for a budget?

Net pay is usually the budgeting figure because it is the amount paid after payroll deductions. Gross pay is useful for comparing jobs and tax bands.

Why does taxable pay differ from gross pay?

Pension method, salary sacrifice, taxable benefits or payroll adjustments can make taxable pay differ from the headline gross pay.

Can PayBreakdown read or store my payslip?

No. These pages explain payslip terms. They do not upload, store or read payslip files or employer portal data.
