Direct 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.

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?
