Setting up payroll for your business in the UK can seem complex at first. However, with the right steps in place, it becomes a manageable and fully compliant process.

In this guide, our Payroll Master, Mark Sapsford, who brings over 25 years of experience in the payroll and HR industry walks you through the essential steps to get your payroll up and running smoothly.

1. Register as an Employer with HMRC

The first step is to register your business as an employer with HM Revenue & Customs (HMRC).Once registered, you’ll receive a PAYE (Pay As You Earn) reference, which is essential for:

• Managing payroll
• Submitting reports
• Communicating with HMRC

Without this, you cannot legally process payroll in the UK.

2. Choose a Payroll Solution

Next, you’ll need to decide how you want to run your payroll.Your main options are:

• Payroll software
• Outsourced payroll provider

Whichever route you choose, it’s crucial that the solution is HMRC-recognised and compliant, ensuring that all submissions are accurate and filed on time. Many businesses opt for outsourced payroll providers, such as PayCheck, to reduce admin and eliminate compliance risks.

3. Collect Employee Information

Before running payroll, you must gather and maintain key employee details, including:

• Salary or hourly pay
• Tax codes
• National Insurance numbers
• Start dates and contract details

Accurate records are critical to ensure correct payments and compliance with HMRC requirements.

4. Process Payroll Calculations and Reporting

Payroll involves more than just paying employees.Each pay cycle, you’ll need to:

• Calculate gross pay
• Deduct Income Tax and National Insurance
• Apply any other deductions (e.g. student loans, pensions)

You must then report this information to HMRC using Real Time Information (RTI) every time employees are paid.

5. Set Up Pension Auto-Enrolment

UK employers are legally required to provide a workplace pension. This includes:

• Enrolling eligible employees automatically
• Managing contributions from both employer and employee
• Submitting pension data to your provider

Failing to comply can result in penalties, so this step is essential.

6. Make Payments on Time

Finally, ensure you have a reliable payment process in place.You’ll need to:

• Pay employees on time (commonly via BACS or Faster Payments)
• Pay HMRC for tax and National Insurance liabilities by the required deadlines

Consistency and timing are key to maintaining compliance.

Why Accuracy and Compliance Matter

At every stage of payroll, accuracy is critical.Mistakes can lead to:

• HMRC penalties
• Employee dissatisfaction
• Unnecessary stress for your business

That’s why many growing businesses choose to outsource payroll ensuring everything from HMRC reporting to pension compliance is handled by specialists, allowing business owners to focus on growth.
