Understanding Your First UK Payslip

Read your pay, deductions and tax code, and know when something is worth querying.

When this helps: First employment or first payday

What you end up with: You can explain every line of your payslip and know what to check with HMRC.

Time: about 20 minutes

The lines that matter

  • Gross pay, then each deduction, then net pay — the figure that reaches your account.
  • Your tax code, which tells the employer how much tax-free pay to apply.
  • National Insurance contributions and, if you have joined one, pension contributions.

Why a tax code can be wrong

  • Incorrect or incomplete starter information can cause you to pay too much or too little tax.
  • If you have a P45 from a previous UK job, give it to your employer.
  • If you do not have a P45, the HMRC starter checklist may be the right route.

Checking it yourself

  • Sign in to your personal tax account to see the code HMRC holds for you.
  • Query a code with HMRC rather than with your employer — the employer applies it, HMRC sets it.
