Onboarding Overview
Understanding your payslip
Payslips under umbrella payroll arrangements can include a number of different lines. Understanding what each line represents is important — though specific advice should always be sought from a qualified adviser.
Gross pay
The total amount earned before any deductions are applied. This is typically based on the agreed assignment rate and hours or days worked as recorded in your timesheet.
Employer National Insurance
In umbrella payroll arrangements, employer National Insurance contributions are typically deducted from the assignment rate. The payslip should set out how this is applied.
Employee National Insurance
Employee National Insurance contributions are deducted from gross pay at the applicable rate, based on earnings and current HMRC thresholds. Specific rates depend on individual circumstances.
Income Tax (PAYE)
Income tax is deducted at source under PAYE. The amount deducted depends on your tax code, personal allowance and total income for the tax year. This is not tax advice — confirm your position with a qualified adviser.
Holiday pay
Holiday pay may be accrued or paid as part of each payment, depending on the arrangement. The payslip should clearly indicate how holiday pay is treated. Confirm details directly.
Apprenticeship Levy
Employers with a large enough payroll may be subject to the Apprenticeship Levy. The payslip should set out whether this applies. Specific application depends on the arrangement in place.
