Christmas party and gifts for dental practice staff: the £150-a-head limit and the £50 trivial benefit, worked on a 12-person team

The practice manager books a table for the Christmas meal, adds a round of drinks and a minibus home, and nobody adds it up per head until the accountant asks. We read two primary pages on 27 October 2026 and worked the sums on a dental practice team.

What the two pages say

From section 264 of the Income Tax (Earnings and Pensions) Act 2003, as the legislation.gov.uk text reads:

• The event is an annual party or similar yearly function that an employer provides for employees, and it is available to them generally or to those at a particular location.
• With one such event in a tax year, no income tax arises if the cost per head is £150 or less.
• The cost per head is the total cost of the event, plus any transport or accommodation provided for people attending, divided by the number of people attending, and attendees need not be employees.
• The total cost includes VAT on the expenses.
• With two or more events in a tax year, one or more can be exempt if their cost per head is £150 or less, or £150 or less in aggregate.

From the GOV.UK trivial benefits page, a benefit is exempt if:

• it cost £50 or less to provide,
• it is not cash or a cash voucher,
• it is not a reward for work or performance,
• it is not in the terms of the contract.

The page also says that trivial benefits given through salary sacrifice are not exempt, and that a director of a close company cannot receive more than £300 of them in a tax year.

Check one: the most the practice can spend

Cost per head is the whole bill divided by everyone who attends, so the ceiling is £150 times the head count.

Check two: a real budget, line by line

That is £33.75 under the limit, or £540 in total (£2,400 - £1,860). Add a drinks package of £480 and the total is £2,340, which is £146.25 a head (£2,340 / 16): still inside. Add a further £60 and the total is £2,400, exactly £150.00 a head, the most that fits.

Check three: the guests who do not come

The sum divides by people who attend, not people booked. Take the £2,340 plan above and lose two guests on the night:

Fourteen attendees cap the spend at £2,100, so a £2,340 bill is £240 over. We did not read how HMRC treats a missed limit, and the section we read gives no part-exemption, so ask your accountant what happens to the whole event if the per-head figure is missed. Chairside, this is why a firm headcount, with a deposit policy for no-shows, matters before the bill is signed.

Check four: a gift on top

A £35 hamper for each of the 12 staff costs 12 x £35 = £420. It passes the £50 test if it is not cash or a voucher that works as cash, is not a reward for performance and is not promised in the contract. A £55 gift fails the first condition: £55 is more than £50. We did not read whether the party limit and the trivial benefit exemption can be used together for the same person in one year, so check that before you rely on both.

What to keep

Keep the invoice, the guest list and the attendance on the night, because the sum needs all three. The same staff costs show up elsewhere: see the annual employment allowance for a practice payroll, the sick pay cost per nurse and the hourly rate a surgery has to earn to break even.

What we did not read

We did not read the HMRC manuals on how to report or settle a taxable party, the rules on PAYE settlement agreements, the National Insurance treatment of a failed party, or the position of a sole-principal practice with no employees attending. The budget figures are invented to show the sums.

Overlyft builds AI staff who join the team, and one of them can do this specific task: take the booking list, add up the invoices and taxis, and flag the per-head figure before the bill is paid, for the practice manager to review and approve.
