Using the best payroll service can simplify payroll, reduce admin, and help ensure employees are paid accurately and on time. This guide covers the key steps and tools you need to run payroll with confidence.
What is Payroll and Why Is It Important?
Payroll is the process you use to work out employee pay, make the right deductions, and pay people for the work they have done. It also covers what you owe to HM Revenue through income tax and national insurance, plus amounts due to other bodies such as pension funds. If you employ staff, payroll is not optional. It must be done in line with tax and employment rules.
Why does that matter to you? Because accurate payroll protects your business and your team. Employees expect to be paid correctly and on time, and HM Revenue expects real-time information through payroll reporting. For a small business in the UK, the basic set-up steps are simple: register as an employer, get payroll software or a payroll provider, collect employee details, run calculations, pay staff, and submit reports.
How Payroll Works for Employers?
From an employer’s side, the payroll process follows a set routine each pay period. You collect pay data, such as salary, hours, overtime, sick leave, or holiday pay. Then you use payroll software to calculate gross pay, payroll deductions, and the final take-home amount. Your PAYE reference links the payroll to your business, and the figures must match the details held for each employee.
After that, you pay wages and send payroll information to HMRC. This is usually done through a Full Payment Submission, and in some cases an Employer Payment Summary too. To calculate the correct tax and National Insurance, you need the employee’s tax code and National Insurance category, along with accurate pay figures. The main building blocks behind those calculations are worth understanding first.
What Do You Need to Start Running Payroll?
Before you start the payroll process, you need a few essentials in place. First, register as an employer with HMRC before your first payday. HMRC then sends you a PAYE reference number and an accounts office reference, both of which you need for reporting and payments.
You also need a payroll system. That might be payroll software, HMRC’s Basic PAYE Tools if you have fewer than 10 employees, or support from a payroll provider. Alongside that, collect accurate employee information and personal information so your first pay run starts cleanly.
1. Registering as an Employer with HMRC
If you want to run payroll, you must register your business as an employer with HM Revenue before your first payday. It is best to do this early, because set-up can take time. The compiled guidance says you can register ahead of the first pay date, and waiting too long can delay your payroll process.
After registration, HMRC sends key references to your business. One is your PAYE reference, which identifies your employer payroll records. You will use it when submitting pay details and when checking HMRC payroll notices.
At that point, you can choose how to manage payroll. Some businesses use software, while others appoint a payroll provider such as an accountant or bureau. Once your details are live, you can begin running payroll and submitting forms like the Employer Payment Summary where needed.
2. Essential Information to Collect from Employees
Good payroll starts with accurate employee information. HMRC needs enough detail to identify each person correctly, usually through a mix of name, address, and National Insurance number. You also need the information required to pay wages and apply the right deductions.
Missing details cause delays and errors. That can affect tax, pay, and reporting. If an employee has a P45, that helps with their tax code. You may also need information on deductions such as student loan repayments or items linked to employee expenses and benefits.
Useful details to collect include:
- Personal details such as name and address
- National Insurance numbers and tax information
- Bank details for salary payments
- Any information affecting student loan repayments or deductions
Payroll Set-Up Options for Small Businesses
Small businesses have a few ways to manage payroll. You can run it yourself with payroll software, use HMRC’s free tools if you have fewer than 10 employees, or outsource the work to payroll provider service providers such as accountants or payroll bureaux. Each option supports the same payroll process in a different way.
The right choice depends on your team size, complexity, and time. Some accounting software includes payroll features too. To help you decide, it is useful to compare manual payroll with software-based systems first.
Manual Payroll vs Payroll Software
You can run manual payroll, but it takes more effort and leaves more room for error. You have to work through pay, deductions, forms, and checks yourself. That may be manageable with very few employees, but it becomes harder as your payroll grows.
Payroll software speeds things up and reduces mistakes. It can calculate pay, create payslips, and send information to HMRC. A payroll provider can take even more work off your hands if you want outside support.
| Payroll Option | How It Works | Best For | Limitations |
| Manual Payroll | You calculate employee pay and maintain payroll records yourself. | Very small teams | Requires more administrative work and carries a higher risk of errors. |
| Payroll Software | The software automatically handles payroll calculations and submissions. | Small and growing businesses | You are still responsible for managing payroll inputs and payments. |
| Payroll Provider | An external payroll specialist manages the payroll process on your behalf. | Businesses looking to reduce administrative workload | Involves an ongoing service cost. |
Choosing the Right Payroll Solution for Your Company
Choosing a payroll solution comes down to how much support you need. If your team is small and your pay arrangements are straightforward, payroll software may be enough. If payroll is taking too much time or involves lots of changes, a payroll provider or payroll service may be the better fit.
Outsourcing can make life easier because service providers handle calculations, reporting, and routine admin. That frees you to focus on running the business. For many small businesses, the best option is the one that keeps payroll accurate without adding pressure.
When comparing options, look at:
- Team size and payroll complexity
- Whether you need hands-on help from service providers
- If the payroll software creates payslips and HMRC submissions
- How well the solution fits your budget and workflow
Step-by-Step Guide: How to Do Payroll for Your Small Business
Once your set-up is done, the payroll process follows the same pattern each pay run. You gather payroll data, check employee details, complete payroll calculations, pay staff, and send real time information to HMRC. A payroll system or payroll software can automate much of the routine work.
If you prefer not to manage it alone, a payroll provider can also handle these tasks. The six steps below show the usual order for small business payroll, from preparing records to keeping everything organised after payday.
Step 1: Gather Employee and Company Details
Start with the basics. Before you can pay anyone, you need complete employee information and the core details for your own business. This gives your payroll a clean foundation and helps avoid mistakes when you process the first run.
On the company side, keep your PAYE reference number ready. On the employee side, make sure all personal information is current and clear. If records are incomplete, tax and payment issues can appear straight away.
Check that you have:
- Employee details such as full name and address
- Bank details for wage payments
- National Insurance and tax information where available
- Your business PAYE reference number and related employer records
Step 2: Set Up Your Payroll System
Next, choose how you will run payroll day to day. Your payroll system can be software you manage yourself, HMRC Basic PAYE Tools for very small employers, or support from a payroll provider. The best option is the one you can use accurately and consistently.
When setting it up, enter the employer details HMRC has issued. These include your PAYE reference and accounts office reference. Without them, your reporting and payment records will not line up properly.
Your set-up should include:
- Employer details including PAYE reference
- Accounts office reference for HMRC payments
- Pay dates and pay frequency
- Employee records inside the payroll software or provider system
Step 3: Calculate Employee Pay and Deductions
Now you can work out what each person should receive. Begin with gross pay. For salaried staff, that may be a fixed amount. For hourly workers, it is usually the hourly rate multiplied by hours worked, plus any overtime, bonuses, or holiday pay.
Then apply payroll deductions to reach net pay. These can include tax deductions, national insurance contributions, pension contributions, and other required amounts. The right figures depend on the employee’s tax code and payroll details, so accuracy matters.
Typical checks include:
- Gross pay based on salary or hourly rate
- Overtime, bonuses, and holiday amounts
- Tax deductions and national insurance contributions
- Final net pay before the payment is approved
Step 4: Make Salary Payments to Employees
Once calculations are approved, you move to the payment stage. This is where the payroll process becomes real for your team. Employees expect the correct amount to land on time every pay period, so payment accuracy is just as important as calculation accuracy.
Most employers pay directly into a bank account. Some businesses may use other methods, but whatever you choose, the payment method should match the agreed arrangement. If you use a payroll provider, they may support the process, but you still need to ensure wages go out on schedule.
Before paying, confirm:
- The correct employee pay for the pay period
- The right bank account details for each worker
- That payslips are ready to issue
- The payment date matches your payroll process timetable
Step 5: Submit Real Time Information (RTI) to HMRC
Submitting Real Time Information (RTI) to HMRC is a crucial part of the payroll process. For small businesses, it’s essential to accurately report employee pay and deductions, including income tax and National Insurance contributions, within specific deadlines. The payroll software you choose should facilitate this task efficiently, ensuring that each Full Payment Submission (FPS) is submitted punctually. On your first payday, you’ll need to include critical details such as employee information, tax codes, and PAYE reference numbers. This will help you stay compliant with legal requirements and avoid discrepancies in payroll records.
Step 6: Maintain Payroll Records and Payslips
Payroll does not end once wages are paid. You also need to keep good payroll records and provide payslips. Payslips should show gross pay, deductions, net pay, and the payment method. Employees rely on them, and they are also a legal requirement.
Strong records help with queries, audits, and year end work. They also make it easier to track employee leave, changes in pay, and deductions over time. If you use a payroll provider or payroll service, records may be stored in the system, but you still need proper oversight.
Keep and review:
- Payroll records for each pay run
- Payslips issued to employees
- Details of employee leave and pay changes
- Year end information for the end of the tax year
Legal Responsibilities and Compliance for UK Payroll
Running payroll means more than paying wages. You also have legal duties around pay, reporting, and record-keeping. Your payroll process must support statutory pay, sick pay, and statutory sick pay rules, while also ensuring that pay never falls below the national minimum wage where it applies.
You must keep payroll records, use your PAYE reference correctly, and file real time information on time. If mistakes happen, HMRC can issue penalties or challenge your records. The next two sections cover the most important compliance areas for employers.
Minimum Wage and Statutory Pay Compliance
You need to check that employee pay meets legal pay floors. An employee’s hourly pay must not fall below the national minimum wage, and workers above the relevant age threshold must receive at least the national living wage. This matters even more when pay changes because of absences or deductions.
Statutory pay also needs careful handling. That can include sick pay, holiday pay, and family-related payments for eligible employees. If your payroll does not reflect these correctly, both compliance and trust can suffer.
Focus on these checks:
- Confirm pay stays above the minimum wage rules
- Review rates against the national minimum wage and national living wage
- Apply statutory pay correctly for eligible employees
- Record sick pay and holiday pay accurately in payroll
Record-Keeping Requirements for Employers
Employers must keep clear payroll records for at least three years. That record trail helps if HMRC checks your files or if an employee raises a query about their pay. Good records also support a smoother payroll process throughout the year.
Your records should link payments, deductions, and employee details to the correct employer account. That includes documents used at year end and at the end of the tax year. If your system is organised, annual reporting becomes far less stressful.
Important records include:
- Payroll records for pay, deductions, and submissions
- Employee details and changes to those details
- Employer information including PAYE reference
- Year end documents such as P60-related records
Common Payroll Challenges and Mistakes to Avoid
Payroll mistakes usually start with poor data, missed checks, or late reporting. A wrong tax code, missing hours, or incorrect payroll deductions can quickly affect pay and compliance. Even a simple error can create extra admin and upset employees.
The good news is that many problems are preventable. A clear payroll process, reliable payroll software, and support from a payroll provider can reduce risk. Next, let’s look at how to prevent errors and what happens when mistakes are not fixed properly.
How to Prevent Payroll Errors
The best way to prevent payroll errors is to start with clean records. Incorrect employee information creates problems that spread through tax, benefits, and pay. Small checks at the start of each cycle can save a lot of time later.
You should also review timesheets, pay changes, and deductions before payroll is approved. Payroll software helps by automating calculations, while a payroll provider can add expert oversight if your process is becoming too complex.
Practical ways to reduce mistakes include:
- Keep employee information accurate and up to date
- Check payroll data before each pay run
- Review hours worked, overtime, and absences carefully
- Use payroll software or a payroll provider for consistency
