Payroll Outsourcing: Useful Things to Reduce Costly Payroll Mistakes

Payroll Outsourcing: Useful Things to Reduce Costly Payroll Mistakes

March 04, 2025

Year-end payroll is a tough nut to crack. The 2024 Autumn Budget brought in some significant changes that will keep accountants on their toes. With updates to payroll calculations, tax codes, and compliance, businesses will be looking to their accountants to help make sense of it all. This is where accountancy firms can really seize the moment. Increased demand translates to more opportunities, higher revenue, and the chance for strategic growth. But with that growth comes a level of risk. Payroll errors can be expensive, and no firm wants to end up on the wrong side of them.

Let’s dive into some of the most common payroll mistakes in the UK—and, more importantly, how to steer clear of them.

1.   Missing Payroll Deadlines


One of the most critical payroll errors is failing to meet key HMRC deadlines. Late submissions can result in penalties from HMRC and dissatisfaction from clients. To mitigate this, establish automated reminders and a clear internal process to ensure submissions are timely and accurate.

2.   Incorrect Employee Tax Codes


The recent changes in the Autumn Budget mean tax codes may need updating. Incorrect tax codes could lead to employees paying too much or too little tax. Always verify tax codes with HMRC before processing payroll to avoid errors.

3.   Inaccurate NI Calculations


National Insurance (NI) contributions are subject to change, and failure to update payroll software or errors in manual calculations can create serious problems. Regularly use HMRC's online calculators and ensure your payroll system is always up to date to prevent mistakes.

4.   Not Processing Employee Benefits Correctly


Benefits such as company cars, health insurance, and bonuses must be reported accurately. Misreporting or failing to report employee benefits can lead to incorrect tax deductions. Make sure P11D forms are completed correctly and submitted on time.

5.   Overlooking Pension Contributions


Auto-enrolment pension schemes are governed by strict rules, and failure to adjust contributions in line with the latest thresholds can result in compliance issues. Regularly review pension settings to ensure adherence to current regulations.

6.   Failing to Distribute P60s on Time


P60s must be distributed to employees by 31st May each year. Any delay in issuing these documents could lead to complaints and harm your firm’s reputation. Automate the distribution process to ensure timely delivery.

7.   Overlooking Leavers and Starters


Payroll errors often arise from incorrect handling of employees who have joined or left the company. Ensure P45s are issued correctly, and that new starters are set up with the correct tax codes and details from the outset.

8.   Ignoring Compliance Changes


Tax laws, National Insurance thresholds, and minimum wage rates are regularly updated. Falling behind on compliance changes can lead to penalties and dissatisfied clients. Keep up to date with HMRC updates and engage in payroll training to stay ahead of regulatory changes and avoid UK payroll penalties.
