A sample answer to question 1

Can you talk me through how you would process a monthly payroll from start to finish, including the checks you do before releasing payments?

I begin by collecting and validating the month's changes: new starters with their starter checklist and P45 or declaration, leavers with last working day, pay rises, overtime, expenses, statutory payments and deductions. Each change needs evidence of authorisation, and I never process a bank detail change without verifying it with the employee by a separate channel. After input, I run a draft payroll and compare it with the previous month: total gross, net, headcount, tax and National Insurance, then investigate variances over a tolerance, negative pays and unusually high figures. I check pension contributions, student loans and attachments of earnings. Once corrected, I produce the final reports, send the payment file for approval to a second person, and submit the FPS to HMRC on or before payday. After payday I distribute payslips, send the journal and pension files to the relevant teams and pay the HMRC liability by the 22nd. I file everything in an audit-ready way.

Common mistake to avoid: Skipping the variance review; Processing bank changes without verification
