UK payslips — the complete hub
Everything PaySlipCheck publishes about UK payslips. Start with the three tools below. The guides underneath explain every line, every code and the common things people check when a payslip looks wrong.

About this hub
PaySlipCheck's payslip hub exists to answer three questions: what does this line on my payslip mean, is the figure right, and what should I do about it if not. Every page uses current 2026/27 UK tax year figures from HMRC and (for Scotland) gov.scot. Last reviewed October 2026.
Our full editorial approach is on the editorial standards page; the calculator detail is in the methodology. If you spot anything off, please get in touch — we treat corrections as a priority.
