Auto-Enrolment Pensions: What Business Owners Keep Getting Wrong
Auto-enrolment has been a legal requirement for UK employers since 2012, yet many businesses still struggle to get it right. From missed deadlines to incorrect contribution calculations, non-compliance can lead to fines, payroll errors, and employee dissatisfaction. In this guide, we’ll cover the most common auto-enrolment mistakes businesses make—and how you can stay on the right side of The Pensions Regulator.
1. Overlooking Your Auto-Enrolment Duties
Many small business owners mistakenly believe auto-enrolment only applies once they hit a certain number of employees. In reality, as soon as you hire your first eligible worker, you have legal responsibilities.
These include assessing your workforce, setting up a qualifying pension scheme, enrolling eligible staff, and beginning contributions by your "duties start date." Missing this can trigger compliance notices and financial penalties.
2. Incorrectly Assessing Employee Eligibility
Auto-enrolment doesn’t just apply to full-time employees. Part-time, seasonal, and even temporary staff may qualify depending on their age and earnings.
Some businesses fail to carry out regular assessments, especially when employee circumstances change. This can result in eligible employees being left out of the pension scheme, potentially breaching regulations.
3. Poor Communication with Staff
Auto-enrolment legislation requires employers to inform workers in writing when they are enrolled. This must include key information such as contribution rates, pension provider details, and the right to opt out.
Failure to provide timely and accurate communications could lead to confusion, opt-out issues, or worse—regulatory breaches.
4. Miscalculating Contributions
One of the most common auto-enrolment mistakes is miscalculating pension contributions. Errors often occur due to:
Using the wrong definition of qualifying earnings
Applying incorrect percentages
Failing to update rates following changes in employee wages
Even minor missteps can have long-term financial implications for both employer and employee, and could result in underpayment or overpayment into pensions.
5. Forgetting Re-Enrolment and Re-Declaration
Every three years, employers must re-enrol eligible employees who have previously opted out, and submit a re-declaration of compliance to The Pensions Regulator.
Many businesses simply forget this requirement, or assume it only applies when there are changes to the workforce. Skipping this essential step risks falling out of compliance—even if everything else has been running smoothly.
6. Manual Processes That Lead to Mistakes
Running auto-enrolment manually can be time-consuming and error-prone. With pension submissions, employee assessments, and contribution updates required every pay period, it’s easy to see how things get missed.
Modern payroll software—especially when managed by professionals—can automate these steps and ensure nothing slips through the cracks.
