Annual Staff Party Tax Exemption: The £150 Per Head Rule Explained 2026

Rewarding your team with a social event is good for morale and good for business. Helpfully, HMRC also allows employers to provide annual staff parties entirely free of Income Tax and National Insurance — provided the cost per head stays within the £150 annual exemption.

The rules are more nuanced than they first appear. The £150 is a combined annual limit across all qualifying events, the cost calculation is all-inclusive (VAT, transport, accommodation), and exceeding the limit even by £1 per head can turn the entire event into a taxable benefit in kind. This guide explains the full rules for 2026/27 so you can plan events that stay within the exemption.

What Is the Annual Staff Party Exemption?

Under HMRC's rules (set out in the Employment Income Manual at EIM21690), an annual party or similar social function is exempt from being treated as a taxable benefit in kind if it meets the following conditions:

1. The cost per head does not exceed £150 (inclusive of VAT) across all qualifying annual events in the tax year.
2. The event is open to employees generally — or to all employees at a particular location or in a particular department.
3. The event is an annual event — it recurs on an annual basis (or is intended to). One-off celebratory events (opening a new office, a retirement party for one employee) are treated differently.

If all conditions are met, neither the employer nor the employee has any tax or NI liability on the value of the benefit. There is nothing to report on a P11D or P11D(b).

How the £150 Per Head Limit Works

It Is an Annual Cumulative Limit

The most important thing to understand is that £150 is the total limit across all qualifying annual events in a tax year, not a limit per event. A company that holds:

• A summer party in July costing £70 per head, and
• A Christmas party in December costing £80 per head,

has a combined per-head cost of £150. Both events are exempt. If the Christmas party costs £90 per head instead, the combined total is £160 — and decisions need to be made about which event loses the exemption (see below).

What Counts Toward the Cost Per Head

The cost per head is calculated by dividing the total cost of the event — inclusive of all associated expenditure — by the total number of attendees (including non-employee guests, if they attend).

Costs that count include:

• Food and drink
• Room hire and venue costs
• Entertainment and performers
• Transport to and from the venue arranged by the employer (taxis, coaches)
• Accommodation provided as part of the event
• VAT (even if the employer can recover it as input tax)

Costs that do not count include:

• Costs that are incidental and incurred by employees personally (personal bar tabs not covered by the employer)
• Costs relating to the business purpose of a meeting that the party is attached to

Guest Attendance Affects the Per-Head Cost

If employees bring partners or guests and the employer picks up the cost for those guests, the cost per head calculation includes the guests' portion. For example, if a Christmas party costs £6,000 total and is attended by 30 employees and 10 partners (40 people total), the cost per head is £6,000 / 40 = £150. The exemption is met exactly.

However, if the same party costs £6,200 for 40 people, the per-head cost is £155. The exemption is broken.

What Happens When the £150 Limit Is Exceeded?

The Exemption Is All or Nothing

Crucially, the £150 exemption is not a fixed allowance that reduces a larger benefit. If the cost per head is £160, the entire £160 is a taxable benefit — not just the £10 excess. This is the most common misunderstanding of the rule.

Which Event Loses the Exemption?

When cumulative per-head costs across the year exceed £150, the employer can choose which event to treat as exempt (up to the £150 limit) and which to treat as taxable. HMRC's guidance allows the employer to nominate the combination of events that maximises the exempt portion. In practice:

• If you have events costing £80 and £90 per head (combined £170), you can nominate the £80 event as exempt (using £80 of the £150 allowance) and treat the £90 event as taxable.
• Alternatively, you can nominate the £90 event and treat the £80 event as taxable.
• You cannot split one event across the limit — the exemption applies per event.

The best strategy is usually to nominate the most expensive single event that fits under £150 as the exempt event, minimising the taxable benefit.

P11D Reporting and Class 1A NI

If an event (or portion of events) exceeds the £150 per head limit, the taxable amount must be reported on form P11D for each affected employee. The employer must also pay Class 1A National Insurance at 13.8% on the total value of the taxable benefits.

For 2026/27, the Class 1A NI rate is 13.8% of the taxable benefit amount. If a company of 50 employees has a party costing £200 per head (the whole £200 being taxable because it exceeds £150 in a single event), the Class 1A NI cost alone is:

50 employees x £200 x 13.8% = £1,380

Employees would also face an Income Tax charge on the benefit, typically collected via a PAYE coding adjustment or Self Assessment.

Does the Exemption Apply to Directors?

Yes. Directors are treated as employees for this purpose and benefit from the same £150 per head annual exemption. This is particularly relevant for small family companies where the workforce consists only of director-shareholders.

A sole director of their own limited company can hold an annual Christmas dinner, include their partner as a guest, and claim the exemption — provided the total cost per head is within £150 and the event meets the annual character test.

HMRC is alert to abuse in this area. A sole director claiming an annual "staff party" at a Michelin-starred restaurant every month would not qualify. The event should genuinely have an annual, social character consistent with how HMRC describes "annual functions."

What Events Qualify?

The exemption covers "annual parties or similar annual functions." HMRC accepts a wide range:

Qualifying:

• Christmas or New Year parties
• Summer barbecues or garden parties
• Annual team dinners or awards evenings
• Department away days with a social element

Not qualifying:

• One-off celebrations (company launch party, retirement party for a single individual)
• Client entertainment events (the exemption is for employees, not customers)
• Events that are not genuinely open to all employees (or all employees at a location)
• Regular monthly or quarterly social events — these lose the "annual" character

Open to All Employees — The Inclusivity Test

The event must be open to all employees generally, or to all employees at a particular location or of a particular description. You do not have to invite all employees to the same event — it is acceptable to hold separate events for different offices or departments — but each event must be open to all employees in that group.

An event held only for senior management, with junior employees deliberately excluded, does not qualify for the exemption. HMRC's view is that exclusivity undermines the social purpose the exemption is designed to recognise.

Practical Planning Tips for 2026

1. Set a budget per head at the outset — agree the headcount and the total budget to ensure you stay within £150 per person including all inclusive costs.
2. Track per-event and cumulative per-head costs — use a simple spreadsheet that accumulates all event costs as the year progresses.
3. Include partner and guest costs in the per-head calculation from the beginning. Guest numbers often change at the last minute, which can push the per-head cost over the limit.
4. Use a PAYE Settlement Agreement (PSA) if you think an event may exceed £150. A PSA allows the employer to pay the tax and NI on behalf of employees under a single annual settlement, rather than requiring individual P11D reporting.
5. Keep records — venue contracts, invoices, attendance lists, and guest lists, in case HMRC queries a claim.

The Bottom Line

The £150 per head annual staff party exemption is a straightforward but easily misapplied rule. The limit is cumulative across all qualifying events in the tax year, inclusive of VAT and associated costs, and if exceeded it makes the entire event taxable — not just the excess. Directors are included. Events must have an annual character and be open to all employees. With careful budgeting and record-keeping, it is entirely possible to hold generous, tax-free events for your team throughout the year while staying comfortably within the exemption.
