The £150 Staff Party Exemption: How It Works and the Cliff-Edge Trap in 2026/27
Employer-funded staff events are tax-free as long as the total cost per head across all annual functions stays at or under £150 — but go a penny over, and the whole amount becomes taxable, not just the excess.
How the £150 Calculation Actually Works
| Included in the Calculation | Excluded |
|---|---|
| Food and drink | — |
| Entertainment and venue hire | — |
| Transport provided as part of the event | — |
| Overnight accommodation provided | — |
| VAT | — |
The calculation is: total cost of the event ÷ total number of attendees (including any invited guests), compared against £150. It's a genuine average cost per head, not a per-employee spending cap that can be topped up differently for different staff.
The Cliff-Edge Trap
| Cost Per Head | Tax Treatment |
|---|---|
| £150 or less | Fully tax-free — the exemption applies |
| £150.01 or more | Exemption lost entirely — full cost per head becomes a taxable benefit-in-kind |
This is one of the most commonly misunderstood benefit-in-kind rules: it isn't a tax-free allowance where only the excess above £150 is taxed (as is the case with some other thresholds). Going even slightly over the limit makes the entire cost per head taxable, which is why careful, conservative budgeting — including all extras like taxis home or an overnight hotel stay — matters more than it might first appear.
One Annual Allowance, Not One Per Event
| Scenario | Outcome |
|---|---|
| Summer BBQ (£60/head) + Christmas party (£80/head) = £140/head combined | Both events fully tax-free — combined total under £150 |
| Summer BBQ (£70/head) + Christmas party (£100/head) = £170/head combined | Combined total exceeds £150 — employer can apply the exemption to one event, leaving the other fully taxable |
Employers running more than one annual staff function need to track the combined cost per head across all of them, not assess each event in isolation, to know whether the exemption still applies.
Not Just for Christmas
The exemption applies to any genuinely annual function open to employees generally (or to all staff at a specific site for multi-site employers) — a summer party, an annual awards dinner, or any other regularly recurring staff event can qualify, provided it meets the same conditions and cost-per-head limit.
If the Exemption Is Lost
- The cost per head becomes a taxable benefit-in-kind, reported via P11D or payrolled benefits.
- The employee typically bears the resulting income tax through their tax code, unless the employer specifically arranges a PAYE Settlement Agreement to cover it on the employee's behalf.
- The employer also pays Class 1A National Insurance on the taxable value.
Given how easily a modest miscalculation (an unplanned taxi bill, a slightly pricier venue than budgeted) can tip an event over £150 per head, building a deliberate buffer into event budgeting is a practical way to avoid triggering the exemption's cliff-edge effect.
