Paye Settlement Agreement Calculation Example

Calculate your potential tax and National Insurance liabilities under a PAYE Settlement Agreement (PSA)

Comprehensive Guide to PAYE Settlement Agreement Calculations

A PAYE Settlement Agreement (PSA) is a formal arrangement with HMRC that allows employers to settle the tax and National Insurance (NI) liabilities on certain benefits and expenses provided to employees. This guide explains how to calculate your PSA liabilities correctly and what factors to consider.

What is a PAYE Settlement Agreement?

A PSA is a voluntary agreement between an employer and HMRC that allows the employer to pay the tax and NI due on:

• Minor or irregular benefits
• Benefits where calculating the exact tax for each employee would be impractical
• Benefits provided to employees that are difficult to value

When Should You Use a PSA?

Consider a PSA when:

1. The benefits are minor or irregular (e.g., small gifts, staff entertainment)
2. Calculating individual tax liabilities would be administratively burdensome
3. You want to simplify your payroll reporting
4. The total value of benefits is significant enough to warrant the 13.8% tax rate

Key Components of PSA Calculations

1. Total Value of Benefits

This includes the cash equivalent value of all benefits covered by the PSA. Common examples include:

Benefit Type	Typical Value Range	Tax Treatment
Staff entertainment	£50 – £500 per event	Taxable if not qualifying exemption
Gifts and awards	£25 – £250 per item	Taxable if not trivial benefit
Relocation expenses	£500 – £10,000	Taxable if over £8,000 exemption
Private medical insurance	£500 – £5,000 annually	Always taxable

2. Income Tax Calculation

The income tax due under a PSA is calculated at a flat rate of 13.8%. This rate represents:

• Basic rate (20%) + higher rate (40%) average
• Plus 13.8% Class 1B NICs (employer’s contribution)
• Simplified calculation compared to individual tax codes

3. Class 1B National Insurance Contributions

Class 1B NICs are payable by the employer at a rate of 13.8% on the total value of benefits included in the PSA. This is in addition to the income tax calculation.

4. Administration Fee

HMRC charges a 1.5% administration fee on the total PSA payment (tax + NICs). This can be included in your calculation for complete accuracy.

Step-by-Step Calculation Process

1. Identify all benefits to be included in the PSA
2. Calculate the total value of these benefits
3. Apply the 13.8% tax rate to the total value
4. Add Class 1B NICs at 13.8% of the total value
5. Calculate administration fee (1.5% of tax + NICs)
6. Sum all amounts for the total PSA payment

PSA vs. Payrolling Benefits: Comparison

Factor	PAYE Settlement Agreement	Payrolling Benefits
Tax Calculation	Flat 13.8% rate	Individual tax codes applied
Administrative Burden	Low (single payment)	High (per employee calculations)
Employee Visibility	No impact on payslips	Visible on payslips
NICs Treatment	Class 1B (13.8%)	Class 1 (13.8%) + Class 1A if applicable
Best For	Irregular/minor benefits	Regular/high-value benefits

Common Mistakes to Avoid

• Underestimating benefit values – Always use fair market value
• Missing the deadline – PSAs must be agreed before 6 July following the tax year
• Including exempt benefits – Trivial benefits (under £50) don’t need to be included
• Incorrect tax rates – Always use the current 13.8% rate
• Forgetting the administration fee – This adds 1.5% to your total cost

Legal and Compliance Considerations

When implementing a PSA, employers must:

1. Apply to HMRC before 6 July following the end of the tax year
2. Keep accurate records of all benefits provided
3. Make payment by 22 October (19 October for postal payments)
4. Submit form PSA1 to HMRC
5. Maintain documentation for at least 3 years

Failure to comply with PSA requirements can result in:

• Penalties for late payment (up to 5% of unpaid tax)
• Interest charges on outstanding amounts
• Potential HMRC compliance checks
• Loss of ability to use PSAs in future years

Real-World Example Calculation

Let’s consider a company with 50 employees that provided:

• Annual staff party costing £15,000
• Christmas gifts worth £3,000 (£60 each)
• Relocation expenses of £20,000 for 2 employees

Total benefits value: £15,000 + £3,000 + £20,000 = £38,000

Income tax (13.8%): £38,000 × 13.8% = £5,244

Class 1B NICs (13.8%): £38,000 × 13.8% = £5,244

Subtotal: £5,244 + £5,244 = £10,488

Administration fee (1.5%): £10,488 × 1.5% = £157.32

Total PSA payment: £10,488 + £157.32 = £10,645.32

Expert Tips for PSA Management

1. Plan ahead: Start gathering benefit information early in the tax year
2. Use technology: Implement payroll software with PSA tracking capabilities
3. Train your team: Ensure HR and finance staff understand PSA requirements
4. Review annually: Assess whether a PSA is still the best approach each year
5. Consider alternatives: For regular benefits, payrolling might be more efficient

Frequently Asked Questions

Q: Can we include all benefits in a PSA?

A: No, certain benefits must be payrolled or reported on P11D forms, including:

• Company cars
• Living accommodation
• Beneficial loans
• Assets transferred to employees

Q: What’s the difference between PSA and P11D?

A: The key differences are:

Aspect	PSA	P11D
Who pays tax	Employer	Employee (via tax code)
Reporting frequency	Annual agreement	Annual return per employee
Tax calculation	Flat 13.8%	Individual tax rates
NICs treatment	Class 1B (13.8%)	Class 1A (13.8%)

Q: Can we change our PSA after submission?

A: You can amend your PSA before the payment deadline (22 October), but after this date, changes require HMRC approval and may incur penalties.

Q: What happens if we miss the PSA deadline?

A: Missing the 6 July application deadline means you’ll need to:

• Report benefits on P11D forms
• Pay Class 1A NICs at 13.8%
• Potentially face penalties for late submission

Conclusion

A PAYE Settlement Agreement can significantly simplify the administration of minor or irregular employee benefits while ensuring compliance with HMRC regulations. By understanding the calculation process, maintaining accurate records, and planning ahead, employers can effectively manage their PSA obligations and potentially reduce their administrative burden.

Remember that while PSAs offer convenience, they may not always be the most cost-effective solution. For regular or high-value benefits, payrolling might provide better value. Always consult with a tax professional to determine the best approach for your specific circumstances.
