PAYE stands for Pay As You Earn and is important for businesses. It’s a system where employers deduct income tax and National Insurance contributions from employee wages.
PAYE for small businesses requires accurate calculations and timely submissions to HMRC. Small business owners must understand their obligations to stay compliant and avoid penalties.
What is PAYE and why it matters?
PAYE registration for small businesses involves several important steps and considerations. When you start employing people, you must register with HMRC immediately for PAYE purposes.
This registration ensures you comply with UK employment and tax laws from day one. PAYE affects every employee payment, so accuracy is absolutely essential throughout the year.

Common PAYE mistakes small businesses make
Below are some of the common PAYE common mistakes which small business make
Mistake One: Missing HMRC PAYE payment process deadlines
Real Time Information reports must be submitted every time you pay employees. Missing RTI submission deadlines can result in significant fines from HMRC authorities.
| Deadline Type | Frequency | Penalty for Late Submission |
|---|---|---|
| RTI Reports | Each pay day | £100-£500 fixed penalties |
| Quarterly Reports | Every three months | Escalating penalties |
| Annual Returns | Once yearly | Up to £3,000 penalties |
| PAYE reconciliation | End of tax year | £100+ per month delayed |
The HMRC PAYE payment process requires strict adherence to submission schedules always. Setting reminders or using automated payroll software helps avoid missing these crucial dates.
Mistake Two: Miscalculating PAYE and National Insurance Contributions
Incorrect PAYE calculations lead to underpayments or overpayments to HMRC regularly. How to calculate PAYE correctly requires understanding current tax thresholds and rates. National Insurance contributions must be calculated accurately for each employee every pay period.
Tax Code Errors
Employee tax codes must be correct to ensure proper deductions from their wages.
Incorrect tax codes lead to either overpaying or underpaying tax throughout the year.
HMRC provides updated tax code information, which you must apply immediately always.
Check current tax codes on HMRC to ensure accuracy.
NI Contribution Mistakes
National Insurance contributions vary based on employee salary, age, and employment status.
Employers must deduct both employee and employer contributions accurately every pay run.
Misalculating these amounts creates compliance issues with HMRC and employee relations problems.
Review National Insurance rates and categories on GOV.UK.
Mistake Three: Overlooking auto-enrolment pension obligations
Under UK law, eligible employees must be enrolled into workplace pension schemes. Between January and June 2024, HMRC issued 28,359 fines for auto-enrolment breaches. Penalties for non-compliance range from £400 to £10,000 per day maximum.
Auto-Enrolment Requirements
- Employers must automatically enrol staff aged 22 to state retirement age.
- Annual re-enrolment of employees must occur every three years without fail always.
- Workplace pension contributions must be submitted accurately and on time to providers.
Mistake Four: Failing to record employee benefits correctly
Taxable benefits such as company cars must be reported to HMRC properly. Travel allowances and expense reimbursements must be tracked and reported accurately. Forgetting to report these creates inaccuracies in your payroll records and filings.
Benefits and Expenses Tracking
- Maintain detailed records of all employee benefits throughout the year always.
- Company benefits have tax implications that affect PAYE calculations for each employee.
- Proper documentation prevents HMRC enquiries and ensures compliance with tax regulations.
Mistake Five: Misclassifying employees as contractors
Incorrectly treating employees as contractors has serious tax and legal consequences. IR35 rules determine whether contractors should be treated as employed staff.
Proper classification of workers is essential for PAYE and National Insurance purposes.
Employee versus Contractor Classification
- Employees receive regular wages with PAYE deductions and National Insurance contributions.
- Contractors invoice for their services and manage their own tax obligations.
- Getting this wrong can result in substantial backdated tax liabilities and penalties.
PAYE deductions and calculations explained
PAYE deductions include income tax and National Insurance contributions from employee wages. Other statutory deductions may include workplace pension contributions and student loan repayments.
Accuracy in calculating these deductions is critical for compliance and employee satisfaction.
How to calculate PAYE correctly?
Use current tax-free allowances, which change annually in the tax year. Current tax-free allowance for 2024/25 is £12,570 for most employees.
Tax rates apply progressively to earnings above the personal allowance threshold each year.
Tax Calculation Example
| Annual Salary | Calculation | Tax Payable |
|---|---|---|
| £20,000 | (£20,000 – £12,570) × 20% | £1,486 |
| £35,000 | (£22,430 × 20%) + (£12,570 × 40%) | £9,728 |
| £50,000 | (£12,570 × 20%) + (£24,928 × 40%) | £12,570 |
National Insurance thresholds differ from income tax thresholds for employees. Employer National Insurance contributions apply at different rates to employee earnings. Using PAYE software for small businesses automates these complex calculations reliably.
PAYE filing deadlines you must know
The PAYE tax year runs from 6 April to 5 April annually. Real Time Information reports must be submitted on or before pay day always. Annual reconciliation must be completed by 19 April following the tax year.
Consequences of missing PAYE filing deadlines
Late RTI submissions result in automatic penalties from HMRC without exceptions. Penalties increase for repeated late submissions, creating escalating costs for non-compliance. Your HMRC account records all late submissions, affecting future business dealings.
| Action | Timeline | Consequence |
|---|---|---|
| RTI submitted late | After pay day | £100-£500 per occurrence |
| PAYE reconciliation delayed | After 19 April | £100 per month late |
| Annual return missing | After deadline | Up to £3,000 penalty |
| No PAYE registration | Before employing staff | £3,000 fixed penalty |
Utilising payroll software reduces the risk of missing critical PAYE filing deadlines.

Accurate tax codes are issued more quickly throughout the tax year. Overpayments and underpayments are identified and corrected faster than manual systems. The system reduces administrative burden on employers and HMRC significantly.
Tax year deadlines and important dates
