Prepare to set up payroll as a sole trader
Before running your first payroll, you need to understand the legal requirements and gather essential information. Sole traders must register as employers and operate PAYE if they hire anyone earning above £96 per week. PAYE is the system for deducting income tax and National Insurance from employee wages, while payroll refers to the entire process of calculating, paying, and reporting employee compensation.
Register with HMRC as an employer before paying any staff. This process can take up to two weeks, so starting early prevents delays that could leave you non-compliant on the first payday. You’ll also need to obtain employer’s liability insurance with at least £5 million cover, which is a legal requirement for most UK employers. Failure to secure this insurance results in fines of £2,500 per day.
Gather the following information before starting:
- Your business details including name, address, and contact information
- Employee personal details including full names, addresses, dates of birth, and National Insurance numbers
- Employee tax codes from their P45 forms or use starter declarations
- Bank account details for making HMRC payments
- Records of employment contracts and agreed salary amounts
Choose whether you’ll handle payroll manually, use specialist software, or outsource to an accountant. Most sole traders benefit from using payroll software compliant with HMRC requirements to automate calculations and submissions.
Pro Tip: Register for PAYE at least three weeks before your first planned payday to account for processing delays and allow time to set up your payroll system properly.
Register for PAYE and set up payroll system
Once you’ve gathered the necessary information, follow these steps to register officially and configure your payroll system. This process ensures you meet HMRC requirements from day one and avoid penalties for late or incorrect reporting.
- Visit the HMRC website and log into your Government Gateway account to register as an employer. If you don’t have an account, create one using your business details.
- Complete the employer registration form providing your business structure, contact details, and the date you’ll first pay employees.
- Wait for your PAYE reference number and accounts office reference to arrive. Registration can take up to 15 working days, so factor this into your hiring timeline.
- Choose payroll software that supports Real Time Information reporting, which transmits employee payment data to HMRC automatically on each payday.
- Input all employee information including National Insurance numbers, tax codes from P45 forms or starter checklists, and salary details.
- Configure payment schedules matching when you’ll actually pay employees, whether weekly, fortnightly, or monthly.
- Run your first payroll calculation checking that income tax, National Insurance, and any other deductions are correct.
- Submit your first Full Payment Submission report to HMRC before or on the employee’s payday.
| Software | Monthly Cost | Features | Best For |
|---|---|---|---|
| HMRC Basic PAYE Tools | Free | Manual calculations, RTI submissions | 1-2 employees, basic needs |
| Xero Payroll | £5-£10 | Automated calculations, integration | Growing businesses |
| Sage Payroll | £7-£15 | Comprehensive features, support | Multiple employees |
| QuickBooks Payroll | £6-£12 | Cloud-based, auto-enrolment | Tech-savvy sole traders |
Remember that sole traders don’t need PAYE for their own income, only for employees. You continue paying yourself through drawings and handling your own tax through Self Assessment. Understanding this payroll processing workflow prevents confusion about when and how to use your PAYE registration.
Pro Tip: Save all confirmation emails and reference numbers from HMRC in a dedicated folder, as you’ll need these details for every payroll submission and future correspondence.
Manage payroll operations and meet ongoing compliance
After your initial setup, maintaining payroll correctly requires consistent attention to reporting deadlines and payment obligations. Real Time Information reporting is the cornerstone of modern UK payroll compliance. You must submit an RTI report every time you pay employees, detailing their gross pay, tax deductions, National Insurance contributions, and any statutory payments. These reports go directly to HMRC through your payroll software on or before each payday.
Make timely PAYE and National Insurance payments to HMRC by the 22nd of each month if paying electronically, or the 19th if paying by cheque. Late payments attract interest at 7.75% as of January 2026, plus penalties that escalate with continued non-compliance. A single late payment can cost hundreds of pounds in unnecessary charges.
Maintain detailed payroll records including payslips, RTI submissions, HMRC correspondence, tax calculations, and employee contracts. HMRC can request these records during inspections, and you’re legally required to keep them for at least three years. Digital records are acceptable provided they’re accurate and accessible.
Your ongoing responsibilities also include managing statutory payments like Statutory Sick Pay, Statutory Maternity Pay, and holiday pay calculations. These obligations apply to all employers regardless of size. Keep up with annual changes to tax codes, National Insurance thresholds, and minimum wage rates that affect your payroll calculations.
Employer’s liability insurance failures result in fines of £2,500 per day, plus an additional £1,000 penalty for not displaying the certificate of insurance where employees can see it.
Avoid these common payroll mistakes:
- Missing RTI submission deadlines, which triggers automatic penalties even if taxes are paid on time
- Using incorrect tax codes leading to under or over-deduction of employee taxes
- Failing to account for benefits in kind such as company cars or private medical insurance
- Not updating employee details when circumstances change, creating discrepancies in HMRC records
- Neglecting to process leavers correctly through P45 forms, leaving employees unable to start new jobs properly
- Ignoring HMRC notices and payment reminders, which escalate into enforcement action
Understanding the broader role of payroll services helps you appreciate why accuracy and timeliness matter so much. Every error creates compliance risks and potential financial penalties that far exceed the cost of getting it right first time.
Verify payroll setup and troubleshoot common issues
Once your payroll is operational, regular verification prevents small errors from becoming costly compliance problems. Check that your PAYE registration is active by logging into your Government Gateway account and confirming your employer reference numbers match those on HMRC correspondence. Verify that your payroll software successfully transmits RTI reports by checking for submission confirmations after each payroll run.
Review employee payslips each period to ensure gross pay, tax deductions, and National Insurance contributions align with employment contracts and current tax rates. Incorrect tax codes are a frequent issue, often caused by HMRC issuing updates you haven’t applied in your system. Cross-reference employee tax codes against HMRC notices and update your payroll software immediately when changes occur.
| Common Error | Impact | Best Practice |
|---|---|---|
| Late RTI submission | Automatic £100 penalty per month | Submit on or before payday every time |
| Wrong tax code | Employee over/under pays tax | Check HMRC notices monthly, update immediately |
| Missed payment deadline | 7.75% interest plus penalties | Set calendar reminders five days before deadline |
| Incomplete employee records | HMRC rejection of RTI | Verify NI numbers and birthdates against official documents |
| No backup of payroll data | Loss of compliance evidence | Cloud storage plus monthly local backups |
Troubleshooting steps for common payroll problems:
- Registration delays: Contact HMRC employer helpline if your reference numbers don’t arrive within three weeks of applying
- RTI rejection errors: Check for missing mandatory fields like National Insurance numbers or incorrect date formats
- Payment allocation issues: Ensure your payment reference includes your accounts office reference and tax year
- Software sync problems: Verify your internet connection and software updates are current, then retry submission
- Employee query resolution: Keep detailed notes of all payroll decisions and calculations to explain discrepancies
Remember that sole traders don’t run payroll for themselves as they’re not employees of their own business. This distinction is crucial for understanding which payments go through PAYE and which don’t. Your personal income as a sole trader continues through drawings recorded in your business accounts, with tax handled through Self Assessment, not payroll.
Consider how to streamline payroll for UK SMBs in 2026 as your business grows. What works for one employee becomes inefficient with five or ten, making it worthwhile to invest in better systems or professional support early.

Frequently asked questions
Do sole traders need to run payroll for themselves?
No, sole traders don’t run PAYE for their own drawings or income. Payroll applies only when you hire employees. You continue handling your personal tax through Self Assessment, taking drawings from business profits rather than paying yourself a salary through PAYE.
When must I register for PAYE?
Register before paying any employees who earn more than £96 per week or receive taxable benefits. Registration must be complete before the first payday to avoid penalties. Start the process at least three weeks early as it can take up to 15 working days.
How long does PAYE registration take?
PAYE registration typically takes up to two weeks from submission to receiving your employer reference numbers. During busy periods it may take longer, so register early to avoid payroll delays. You cannot legally pay employees until your registration is complete.
What records must I keep for payroll?
Keep comprehensive records including payslips, RTI submissions, HMRC correspondence, employee contracts, tax calculations, and payment confirmations. HMRC requires these records to be available for inspection and kept for at least three years. Digital records are acceptable if accurate and accessible.
What fines exist for payroll non-compliance?
Late PAYE payments attract interest at 7.75% plus escalating penalties starting at 1% of the tax due. Late RTI submissions incur automatic £100 monthly penalties. Lack of employer’s liability insurance results in £2,500 daily fines plus £1,000 for not displaying the certificate. Penalties compound quickly, making compliance essential.
