Avoid P11D Issues with the Annual Party Exemption
Employers organising staff events and directors of close or owner-managed companies who want to ensure the annual party exemption is applied correctly.
Explaining when the annual function exemption applies, how the £150 per head annual limit works, and what happens if the limit is exceeded.
Where the conditions are met, an annual party or similar event can be provided without triggering Income Tax or National Insurance. If the exemption fails, the full cost per head becomes taxable (not just the excess), and P11D reporting and Class 1A National Insurance may apply.
When Does the Annual Party Exemption Apply?
The cost of a staff party or other annual entertainment is generally allowed as a deduction for tax purposes. If you meet the various criteria outlined below, then there is no requirement to report anything to HMRC or pay tax and National Insurance. There will also be no taxable benefit charged to employees.
- An annual Christmas party or other annual event offered to staff generally is not taxable on those attending provided that the average cost per head of the function does not exceed £150.
- The event must be open to all employees. If a business has multiple locations, then a party open to all staff at one of the locations is allowable. They can also have separate parties for separate departments, but employees must be able to attend one of the events.
- There can be more than one annual event. If the total cost of these parties is under £150 per head, then there is no chargeable benefit. However, if the total cost per head goes over £150 then whichever functions best utilise the £150 are exempt and the others taxable. Note, the £150 is not an allowance and any costs over £150 per head are taxable on the full cost per head.
- It is not necessary to keep a running total by employee but a cost per head per function. All costs including VAT must be considered. This includes the costs of transport to and from the event, food and drink and any accommodation provided.
Understanding the £150 Per Head Limit
The £150 limit applies per head and includes:
- VAT
- Food and drink
- Entertainment
- Transport and associated costs
The limit applies to the total annual cost of all qualifying events in the tax year.
If the total cost per head exceeds £150, the exemption does not apply to that event.
Multiple Events in One Tax Year
An employer may hold more than one annual event in the same tax year, for example:
- A summer event
- A Christmas party
The combined cost per head of all qualifying events must not exceed £150 in the tax year for the exemption to apply.
Director-Only or Small Company Events
In close or owner-managed companies, events may involve only directors.
The exemption can still apply provided the event meets the qualifying conditions and is open to all employees of the company.
Risks and Compliance Considerations
If the exemption conditions are not met:
- The full cost per head becomes taxable
- The benefit may need to be reported on a P11D
- Class 1A National Insurance may be payable
Because the £150 limit is a cap and not an allowance, exceeding it by even a small amount can result in the entire amount being taxable.
Real-World Application
Common compliance issues arise where:
- The per-head cost is calculated incorrectly
- Multiple events are held without reviewing the annual total
- Small company events are assumed to qualify automatically
Reviewing expected costs before booking helps prevent unintended tax consequences.
