If you’ve ever found yourself thinking, “Payroll can’t be that complicated, can it?”—you’re certainly not alone.
Over the years, we’ve heard just about every payroll myth imaginable. While some are harmless misconceptions, others can lead to costly mistakes or unnecessary stress for employers.
So, let’s bust a few of the most common payroll myths we still hear today.
Myth 1: “Payroll is just pressing a button.”
If only it were that simple!
Modern payroll software is incredibly clever but it’s only as accurate as the information entered into it. Payroll involves much more than producing payslips. Every pay run can include changes to tax codes, statutory payments, pensions, salary sacrifice arrangements, holiday pay, new starters, leavers, and Real Time Information (RTI) submissions to HMRC.
The software does the calculations—but people still need to make sure everything behind those calculations is correct.
Myth 2: “HMRC will tell me if I’ve made a mistake.”
Unfortunately, that’s not always the case.
Some errors may not become apparent for months or even years. By then, correcting them can involve back payments, revised submissions and plenty of administration.
Taking a little extra time to check payroll before it’s submitted can save a great deal of hassle later on.
Myth 3: “Paying staff monthly makes payroll easier.”
Not necessarily.
Whether employees are paid weekly, fortnightly, four-weekly or monthly, each payroll has its own considerations. Different pay frequencies can affect holiday calculations, overtime, variable hours and cash flow planning.
There’s no “best” frequency—only the one that works best for your business and your employees.
Myth 4: “National Minimum Wage is straightforward.”
It’s one of the areas that catches employers out most often.
Pay rates change, age bands can change, apprentices have different rules and deductions for things like uniforms or salary sacrifice can sometimes affect compliance.
It’s about much more than simply paying the published hourly rate.
Myth 5: “Small businesses don’t need to worry as much.”
In reality, payroll rules apply whether you employ one person or one hundred.
In fact, smaller businesses can sometimes feel the impact of payroll errors more keenly because there are fewer people available to spot and correct mistakes.
Good payroll practices are just as important for a family business as they are for a large organisation.
Myth 6: “Holiday pay is easy to work out.”
Holiday pay can be surprisingly complex, particularly for employees with variable hours, overtime, commission or irregular earnings.
Recent years have brought several changes and clarifications to holiday pay rules, making it more important than ever to ensure calculations are accurate.
Myth 7: “Payroll never changes.”
If only!
Payroll legislation evolves every year. Tax thresholds, statutory payment rates, pension contributions and reporting requirements are all subject to change.
Looking ahead, employers are already preparing for the introduction of mandatory Payrolling of Benefits in Kind from April 2027, one of the biggest changes to payroll reporting in recent years.
Keeping up with these changes is simply part of running payroll well.
The Bottom Line
Payroll often looks straightforward from the outside, but there’s a lot happening behind every payslip.
The good news is that most payroll issues are entirely avoidable with the right processes, accurate information and a little forward planning. Whether you’re running payroll yourself or simply want to understand it better, separating fact from fiction is a great place to start.
