Head of Payroll Interview Questions UK: 8 Real Questions and What Interviewers Want

Applying for a Head of Payroll job in the UK? Here is what you are likely to be asked. These questions come from our Head of Payroll question bank of 12 questions, written for UK employers at head/director level.

Eight Head of Payroll interview questions, and what the interviewer is thinking

1. What controls would you build into a payroll function to make sure every run is accurate, authorised and auditable?

Why they ask: They want to see that you can design a control framework, not just process payments.

2. Can you explain how Real Time Information reporting works, and what the consequences are of getting FPS and EPS submissions wrong or late?

Why they ask: RTI is the backbone of UK payroll compliance and a Head must own it.

3. It's two days before payday and you discover an interface error has underpaid around 300 employees. What do you do?

Why they ask: This tests crisis management, communication and judgement under time pressure.

4. How do you prepare your team and systems each tax year for the April changes?

Why they ask: They want to know you run payroll proactively and not reactively.

5. Tell me about a time you led a significant change to payroll, such as a system migration or a move to outsourcing.

Why they ask: They are testing delivery of major change while protecting pay accuracy.

6. What are an employer's duties around automatic enrolment, and how does payroll support them?

Why they ask: Pensions compliance is a key risk area that heads of payroll typically share with HR.

7. HMRC opens a compliance check into your PAYE records and asks for documents within 30 days. How do you handle it?

Why they ask: They are looking for composure, process and knowledge of the HMRC relationship.

8. What do you see as the main responsibilities of a Head of Payroll, and what makes someone great at it?

Why they ask: They want to confirm you understand the strategic side of the role beyond processing.

A sample answer to question 1

What controls would you build into a payroll function to make sure every run is accurate, authorised and auditable?

I'd work in layers. Before each run, changes go through a documented cut-off with evidence from HR, and anyone who can input data cannot approve it, so there's proper segregation of duties. During processing I'd use automated validation such as variance reports against the prior period, flagging net pay swings above a set tolerance, new starters with no tax code, and duplicate bank details or National Insurance numbers. After processing, a second person reviews the gross-to-net summary and the BACS file totals before release, and the finance team reconciles payroll journals to the general ledger. I'd keep a monthly reconciliation of HMRC liabilities too. Underneath all that, I'd restrict system access by role, review leaver access quarterly, and agree an internal audit or independent sample test annually. I'd also track error rates, such as payslips corrected per thousand, so we can show improvement to the finance director and external auditors.

Common mistake to avoid: Describing only the checks you personally do; ignoring system access and audit trail
