Service charge rules UK: optional or compulsory, the VAT on it, and who it belongs to

The service charge rules in the UK come down to one question: can the customer say no? If the charge is really optional, it's a tip. No VAT, and every penny goes to your staff under the tipping law. If it's compulsory, HMRC wants 20% VAT out of it, it counts as pay for National Insurance, it still has to go to staff, and since the drip pricing rules came in it has to be inside the price on the menu, not added at the bottom of the bill.

It comes up every year about now, when the Christmas party bookings land and someone asks whether they can stick 12.5% on tables of ten. You can. But "optional" and "compulsory" are two completely different things in law, and it's easy to print one and run the other. Here's how each one actually works, with the sums.

Optional or compulsory: the whole difference on one table

How the two kinds of service charge are treated in England, Scotland and Wales. Sources listed at the bottom.

	Optional (discretionary) service charge	Compulsory service charge
Can the customer refuse it?	Yes, and they must be told so	No
VAT	Outside the scope of VAT	Standard-rated, 20%. One sixth of it goes to HMRC
National Insurance	A gratuity. Whether NI is due depends on how you pay it out	Earnings for Class 1 NI, always
Tipping law (all to staff, no deductions)	Yes	Yes
Must it be in the menu price?	No, it's optional	Yes, under the DMCC Act price rules

Read that bottom row twice. A compulsory service charge has to be in the headline price, it has to go to staff, and you pay VAT on it. So the pub gets nothing from it except the paperwork.

The VAT rule

HMRC's own manual is clear. A tip that's freely given is outside the scope of VAT. A compulsory service charge added to the standard price is part of what the customer pays for the meal, so it's taxable. An optional charge is only outside the scope if the customer has "a genuine option" about paying it.

The tribunal cases HMRC quotes are worth knowing because they're about exactly what pubs do:

• Potters Lodge. A restaurant put a mandatory 10% on every bill and passed it to staff. Taxable. Passing it to staff didn't change that.
• NDP. A restaurant marked its suggested charge as optional on the menu and on the bill. Voluntary, so outside the scope.
• James Dominic Joyce. The menu sets the contract. If the menu says the service charge is optional, writing something different on the bill is too late to change it.

So if you want it to be optional, say so in writing, in two places: on the menu or booking terms, and on the bill. "A discretionary 10% service charge has been added. Please tell us if you'd like it removed." That's the wording that keeps it a tip.

Who the money belongs to

Since 1 October 2024 the tipping law covers service charges as well as cash and card tips, and the statutory code calls the lot "tips". Acas says plainly that it covers service charges whether they're voluntary or compulsory, as long as the employer has control or significant influence over them. A service charge on your till is under your control. So:

• All of it goes to the workers. No deductions except tax and NI. The code doesn't list card processing fees as an allowed deduction, so don't take them.
• It has to be paid out by the end of the month after the customer paid it. A charge on a party on 19 December has to reach staff by 31 January.
• You need a written tipping policy saying how it's shared.
• You keep records of what came in and what went out for three years.

One more change is coming. The Employment Rights Act 2025 adds a duty to consult your staff when you write or change the tipping policy. It was expected in October 2026, then the revised code that goes with it was withdrawn in July for another consultation, and law firms now expect it by the end of 2026. If you're writing a policy now, talk it through with the team anyway. It costs nothing and you'll be ahead of it.

The menu price rule

This is the bit most pubs haven't caught up with. The Digital Markets, Competition and Consumers Act 2024 made it unlawful to show a price without the charges a customer can't avoid. The Competition and Markets Authority's guidance on it, published in November 2025, lists "mandatory cover or service charges at a restaurant" as one of the charges that has to be in the total price. It also counts a menu, including a QR code menu, as an invitation to purchase.

In plain terms: if your service charge is compulsory, a £36 menu with "12.5% service added" underneath isn't allowed. The price on the menu has to be £40.50. Calling it a separate service doesn't help either, the guidance says presenting a charge separately doesn't make it optional.

An optional charge doesn't have to be in the headline price, because the customer can say no. Which is one more reason to keep it optional.

If you only make it compulsory for big tables, my reading is that the price you quote that party in the booking has to include it. That's my reading of the guidance, not a ruling, so if you want a compulsory charge for parties, run your booking terms past your local trading standards first.

The sum on a Christmas party

Twenty people on a £36 menu, which is the 2025 average for three Christmas courses at the big chains. That's £720. Add 12.5% and it's £90.

Twenty covers at £36. My arithmetic, illustrative.

	Optional 12.5%	Compulsory 12.5%
Service charge paid by the party	£90	£90
VAT to HMRC (one sixth)	£0	£15
Counts as pay for Class 1 NI	Depends how it's paid out	Yes, all of it
What the menu must say	£36, charge optional	£40.50 per head
Kept by the pub	£0	£0

The tipping code says it doesn't change the tax rules on tips, and it doesn't spell out how the £15 of VAT on a compulsory charge sits against "pass on all of it". That's a question for your accountant before you set one up, not after. What's certain is HMRC wants its sixth.

Now the bit that matters for your margin. If you want more money from a big party, a service charge isn't how you get it, because none of it is yours. Put the menu price up. £38 a head instead of £36 is £40 more on the table, £33.33 of it yours after VAT, and it lands in your food GP. A compulsory service charge of the same size lands in the staff pot, costs you VAT and NI admin, and still has to be printed in the price. My Christmas menu pricing guide has the plate cost sums for each price point.

How optional charges get paid out, and the NI question

HMRC treats a really optional service charge as a gratuity. Whether National Insurance is due on it depends on how it reaches the staff. Shared out by an independent troncmaster, it can be free of employer and employee NI. Allocated by the employer through payroll, NI is due. Income tax is due either way. HMRC's E24 guide on tips, gratuities, service charges and troncs sets out the conditions, and it's the one document I'd hand anyone running the tips at a busy pub. A compulsory charge never gets the NI break, because HMRC says it isn't a gratuity at all.

What I'd do

Keep it optional. Say so on the booking terms, the menu and the bill. Take it off without a face if someone asks. Put it through the till on its own button, so the service charge lands on the cash-up, the VAT return and the tips record as the same figure. My free cash-up sheet has a tips record tab that works for this, and the cash-up guide covers the card tips trap where the till and the drawer don't agree.

Here's the idea I haven't seen anyone else in pubs talk about. Look at your service charge as a staffing cost line, not income, because that's what the law has made it. Twenty Christmas parties at £90 is £1,800 into the staff pot over December, my illustrative sum. That's real money to a team working the busiest month, and it costs the pub nothing out of margin. Tell the team the number. It's the cheapest retention tool you've got in December, as long as it's handled properly.

And take a deposit when parties book, with your terms in writing. The Christmas party deposits guide covers what the CMA says you can keep when a table doesn't show.

Common questions

Is a service charge mandatory in the UK?

Only if the business makes it compulsory and says so up front. Most UK pubs and restaurants use a discretionary charge, which the customer can ask to have removed. A compulsory service charge must be included in the price shown on the menu under the DMCC Act price rules.

Do you pay VAT on a service charge?

Not on a really optional one: HMRC treats it as a tip outside the scope of VAT. A compulsory service charge is part of the price of the meal and is standard-rated at 20%, so one sixth of it goes to HMRC.

Does the service charge have to go to staff?

Yes. Since 1 October 2024 the Employment (Allocation of Tips) Act covers service charges the employer controls, voluntary or compulsory. All of it must go to workers without deductions other than tax and NI, by the end of the month after it was paid, under a written policy.

Can a pub add a service charge for large groups?

Yes, as long as it's clear before they book. An optional charge just needs to be shown and removable. If it's compulsory for groups, the price you quote that group should include it, and it's taxable for VAT.

Can I deduct card fees from the service charge?

The statutory code says tips and service charges must be passed on without deductions except in very limited cases such as income tax. Card processing fees aren't on that list, so don't deduct them.
