Over 90% of UK businesses admit to monthly payroll mistakes, learn how to avoid them in our upcoming webinar.

With around one third of businesses managing payroll in-house, getting it right is essential. But many UK SMEs aren’t confident running their payroll and with good reason, navigating all the complexities can feel like a minefield. 31% are still managing payroll manually, with this rising to 44% in very small businesses according to recent data that I have seen. 

When deadlines are tight and legislation keeps changing, it’s easy to miss a tax code or misclassify a new hire. These mistakes come with consequences and can lead to fines, a decline in employee trust and wasting valuable time on untangling problems. 

In this session, Liam Sant, Partner Account Executive, and Danilo Alencar, Account Executives at Employment Hero will show you how to avoid the most common pitfalls so you can run payroll with confidence. Employment Hero’s payroll expert Suzanne Gallagher will answer individual questions live throughout the session.

In this practical webinar, we’ll cover:

  • The 5 most expensive payroll mistakes SMEs are still making — including:
    • PAYE and National Insurance miscalculations
    • RTI submission slip-ups
    • Worker misclassification (IR35, freelancers, casuals)
    • Auto-enrolment errors
    • Starters and leavers handled incorrectly
  • Why these issues are so common (yes, even with spreadsheets)
  • What they’re really costing your business
  • How to fix them fast — and prevent them for good
  • How payroll automation can take these risks off your plate

Whether you’re a business owner, leader or HR professional running payroll for the first time, or a seasoned pro, this session will help to demystify the intricacies.
