Introduction:
Payroll is a crucial aspect of any business, ensuring that employees are paid correctly and on time. However, the process can be complex, and even small mistakes can lead to significant issues, such as employee dissatisfaction, legal penalties, and compliance risks. In this post, we’ll explore best practices to help you process payroll accurately and avoid common mistakes that can cause problems down the line.
Understand the Payroll Process.
Before you begin processing payroll, it’s important to fully understand the steps involved. This includes gathering accurate employee data, calculating wages, taxes, and deductions, and ensuring that payments are made on time. Failing to follow these basic steps correctly is one of the most common causes of payroll mistakes.
At AdminBooks, we pride ourselves on delivering fast, accurate, and fully compliant payroll services, ensuring every employee is paid correctly and on time, every time.

Step-by-Step Guide to Doing Payroll Right
1. Register as an Employer with HMRC
Before hiring and paying staff, your business must be registered as an employer with HMRC. This allows you to operate PAYE (Pay As You Earn) and report payroll information in real-time.
2. Use Trusted Payroll Software
Reliable payroll software helps you manage everything from payslips to HMRC submissions. At AdminBooks, we use Xero Payroll, which automates calculations and ensures RTI (Real Time Information) reports are sent accurately and on time.
3. Collect Complete Employee Information
- Ensure you have:
- Full name and contact details
- Date of birth and National Insurance number
- Right-to-work documentation
- Starter checklist or P45
- Bank account details
- Accurate records help prevent errors in pay and deductions.
4. Calculate Pay and Deductions
- You need to calculate:
- Salaries or hourly wages
- Overtime or bonuses
- Statutory sick pay, holiday pay, or maternity pay
- Deductions like PAYE, National Insurance, pensions, and student loans
- Always use the latest HMRC rates and apply the correct tax codes.
5. Submit Payroll to HMRC
Each payday, submit a Full Payment Submission (FPS) to HMRC on or before the payment date. This is a legal requirement, and missing it may result in penalties.
6. Distribute Payslips and Keep Records
Payslips must show gross pay, deductions, and net pay. You’re also required to keep payroll records for at least 3 years.
Common Payroll Mistakes to Avoid.
