The payroll process in the UK: A step-by-step guide

If you’re processing payroll for the first time or reviewing your current workflow, having a clear payroll process is essential. 

Every payroll cycle depends on accurate data, timely approvals and well-connected systems. If one stage is delayed or overlooked, it can lead to payroll errors, payment delays and unnecessary admin. 

In this guide, we’ll walk you through each stage of the payroll process in the UK, explain why every step is important, and share practical tips to help you run payroll more efficiently. 

 

What is the payroll process? 

It might seem like just another business process, but it’s one of the most important workflows in any business. A well-managed payroll process helps ensure workers are paid accurately, on time and in line with UK legislation, while giving payroll teams the confidence that every pay cycle runs smoothly. 

From collecting worker information and calculating pay to issuing payslips and reporting to HMRC, every stage plays an important role. When one part of the process breaks down, it can lead to payroll errors, payment delays and additional work for your payroll team.

The step-by-step payroll process 

Although every business works slightly differently, most payroll operations follow the same six stages. 

Understanding each stage will help you identify where delays and errors are most likely to occur, making it easier to improve your payroll process over time. 

 

Step 1: Collect worker information 

Every successful pay run starts with accurate worker information. 

Before payroll can begin, you’ll need to collect key details such as personal information, bank details, tax codes, National Insurance numbers, pension information, pay rates and employment status. If you’re paying temporary workers or CIS subcontractors, you’ll also need the relevant compliance information before the first pay cycle. 

Taking the time to verify this information upfront helps prevent payroll issues later in the process. 

 

Step 2: Gather payroll data 

Once workers are set up, the next step is collecting everything needed to calculate pay. 

Depending on your workforce, this could include salaries, timesheets, overtime, bonuses, commissions, holiday pay, statutory payments or expenses. Accurate payroll data at this stage helps prevent issues later in the process. 

To understand how inaccurate data leads to payroll mistakes, read our guide on common payroll errors in the UK (and how to avoid them).

 

Step 3: Calculate pay 

With all payroll data collected, you can calculate each worker’s pay. 

This includes gross pay, PAYE, National Insurance, pension contributions, statutory payments, deductions and, where applicable, CIS deductions. Before moving to the next stage, it’s worth reviewing any unusual changes or exceptions to make sure payroll is accurate before approval. 

 

Step 4: Review and approve payroll 

Before payments are released, payroll should go through a final review. 

This is your opportunity to confirm that payroll is accurate, approvals have been completed and no important information is missing. Catching issues here is much easier than correcting them after payday. 

To understand how delayed approvals affect payroll, read our guide on common causes of late payroll and how to prevent them.

 

Step 5: Process payments and issue payslips 

Once payroll has been approved, payments can be processed and payslips issued. 

Before submitting payments, confirm that bank details are correct and payment files have been generated successfully. Completing these checks helps reduce failed payments and unnecessary payroll queries after payday. 

 

Step 6: Reconcile payroll and submit payments to HMRC 

The payroll process doesn’t end when workers are paid. 

After each payroll run, you’ll need to reconcile payments, submit the required information to HMRC, update finance records and resolve any payroll queries. Reviewing each pay cycle also helps identify recurring issues and opportunities to improve future payroll runs. 

Many of the steps above can be simplified or automated with our payroll software like Finity. 

Instead of manually moving data between onboarding, timesheets, approvals, payroll calculations and payments, Finity helps connect the process end to end. This gives payroll teams better visibility, reduces admin and makes each pay cycle easier to control. 

For high-volume teams managing temporary workers, permanent employees or CIS payroll, that means less time chasing information and more confidence before payday. 

 

How much time does the payroll process take? 

The time it takes depends on the number of workers paid each month, the complexity of the workforce, and how much of the process still relies on manual work. 

In our UK Payroll Efficiency Report, payroll professionals said they lose up to 11 hours every week to manual processes and disconnected tools. 

At scale, efficiency makes a major difference. One of our clients pays around 25,000 workers every month with a payroll team of just three people. 

 

How to make your payroll process more efficient 

Many payroll teams are still working across disconnected systems. Our payroll efficiency report found that 70% use multiple payroll systems, with an average of 3.2 systems involved in the payroll process. 

An efficient payroll process isn’t about working faster. It’s about making every stage of the workflow simpler, more connected and easier to manage. 

Start by reviewing where delays and manual work occur. If your team spends time chasing approvals, correcting payroll data or switching between multiple systems, those are often the biggest opportunities for improvement. Improving visibility across your payroll workflow can help you resolve issues before they affect payday. 

The right payroll software can help you reduce the time spent on manual processes and workarounds. When you book an initial 30-minute demo with Finity, we’ll take a closer look at your current process and show where Finity could help make payroll faster, simpler and easier to manage. 

 

Key takeaways 

A reliable payroll process is built on more than accurate calculations. It depends on clear workflows, connected systems and the right information at every stage of the payroll cycle. 

Whether you’re managing permanent employees, temporary workers or CIS subcontractors, following a structured payroll process can help reduce errors, prevent delays and give your team greater confidence every payday.
