Payroll Health Check Checklist: Audit, Compliance and Review

Many finance and HR leaders ask themselves, ‘Is our payroll as healthy as our bottom line?’ but the answer shouldn’t be keeping you up at night.

Long recognised as essential to keeping businesses running, payroll has evolved into a core pillar of modern operations. From building trust with teams to keeping the lights on, but when your business is scaling fast, cracks can start to show.

Things like manual spreadsheets, outdated systems and quick fixes that worked before, simply won’t cut it anymore. This is when you need to do a complete payroll health check, from auditing, to compliance and review.

We’ve devised a payroll health checklist to help you catch errors, manage risk and feel more in control of your business finances.

Why a payroll health checklist is essential

We all know payroll mistakes are expensive but we’re not just talking about the financial costs here. Some mistakes can mean more than a slap on the wrist from HMRC or The Pensions Regulator. The trust a business has with its employees is vital and mistakes with your employees can not only cause mistrust, but confusion, frustration and a drop in morale.

A payroll compliance checklist can help you avoid:

• Costly penalties for non-compliance.
• Employee churn.
• Admin overload from fixing mistakes.

Being proactive is the best plan when it comes to remaining trusted and competitive. Showing your team that they’re valued while freeing up time to focus on growing your business.

What’s included in the payroll health checklist

Our simple quick checklist gives it to you straight. No fluff and no fuss of what you need broken down into logical sections to help you review your business’ payroll quickly.

• Employee classification: Are your contractors actually employees?
• Pay rates and deductions: Is everyone on the right code?
• Timekeeping: Does the data match reality?
• Tax compliance: Are you ready for the new tax year?
• Security: Who has access to sensitive information?

Key areas to review in your payroll health check

If you’re a growing business, there are a few areas to keep an eye on.

Employee classification and records

As your business scales, so do your teams and it’s easy to forget about any freelance or contractors you’ve hired.

• Verify status: Don’t let IR35 trip you up. Ensure your contractors and employees are classified correctly to avoid any nasty surprises.
• Update details: People move and banks change. Ensure your team’s addresses, bank details and tax codes are current.

Pay rates and deductions

Each year the National Minimum Wage and National Living Wage rates change in April. And each year, you must adjust these rates to reflect in your payroll.

• Check the floor: Ensure no one has fallen below the National Minimum or Living Wage after salary sacrifice schemes.
• Review deductions: Double check pension contributions, student loan repayments and court orders.
• Double check National Insurance category: Things like age, or status, like being an apprentice or someone’s location can change, so it’s always best to double check NI categories.

Timekeeping and overtime

Ensure you are paying for exact hours worked and not just a guess.

• Audit the data: Compare the timesheets against approved leave and sickness records.
• Overtime rules: Ensure overtime is calculated correctly according to specific employment contracts.

Tax compliance

This is the big one. HMRC doesn’t accept “we were too busy” as an excuse.

• RTI submissions: Verify that your Real Time Information (RTI) submissions match your internal payroll reports.
• Tax codes: Ensure you are applying strictly effective tax code updates from HMRC.

Benefits and leave

• Statutory pay: Check calculations for Statutory Sick Pay (SSP), Maternity Pay (SMP), Statutory Paternity Pay (SPP), Statutory Shared Parental Pay (ShPP), Statutory Parental Bereavement Pay (SPBP), Statutory Neonatal Care Pay (SNCP) and Statutory Redundancy Pay.
• Holiday pay: Ensure holiday pay calculations include regular overtime or commission where legally required.

Payroll System Security

Payroll data is a goldmine for scammers. Protect it.

• Access control: Remove access for leavers immediately.
• GDPR: Ensure you aren’t keeping sensitive data longer than necessary or sharing it insecurely via email.

Common payroll mistakes to avoid

Even the best teams slip up every now and then. We are human after all. Here are just a few of the common payroll mistakes that we see time and time again.

• Misclassifying employees: Treating an employee as a contractor to save admin is a false economy that can lead to massive back-tax bills.
• Missing birthdays: Age-related changes to National Minimum Wage can catch you out if your system doesn’t flag them automatically.
• Payroll vs. HR disconnect: When HR data (like a salary bump) doesn’t sync instantly with payroll, you get overpayments or underpayments.
• Ignoring the “benefits” trap: Forgetting to report benefits-in-kind (whether you’re payrolling your benefits or submitting P11D’s) accurately.
