Can I Run My Own Payroll in the UK?
First, let’s be clear: the UK payroll system isn’t designed to be simple. It’s a complex beast with more moving parts than a steam engine. You’re not just paying people; you’re deducting tax (PAYE), National Insurance contributions (NICs), student loan repayments, and potentially other deductions like pension contributions or court orders. Each of these has its own set of rules, thresholds, and deadlines.

What’s Involved in Running Payroll?
Running payroll isn’t just about handing out paychecks, it’s a detailed process with plenty of moving parts. From calculating wages to navigating tax deductions and filing reports, there’s a lot to keep track of. Now, take a deep breath before we dive in because you might not be ready for all the work involved.
- Calculating gross wages
This is the total amount your employees earn before any deductions. Think of it as the “before” picture, and the net pay is the “After” Picture.
- Deductions and contributions
This is where things get complicated. First of all, you need to get your PAYE scheme set up, wondering what PAYE is? This is the system for deducting income tax and National Insurance from your employee’s wages.
Secondly, if your employees have student loans, you’ll need to deduct repayments. Lastly, for the workplace pension scheme, thanks to auto-enrolment, you’ll need to deduct contributions from your employees’ pay and pay them into the scheme.
- Net Pay
Payday! Once all the deductions are made, it’s time to pay your employees. This can be done via direct deposit or cheque.
- Reporting to HMRC
You need to report your payroll information to HMRC electronically, usually through Full Payment Submission (FPS) and Employer Payment Summary (EPS). These submissions need to be accurate and submitted on time, or you’ll face penalties.
- Keeping Records
You need to keep detailed records of your payroll for at least three years. This includes things like payslips, P45s (leaving certificates), and records of payments to HMRC.
