How Much Will a Tronc Scheme Save Your Restaurant? A UK Guide

The headline number, before anything else

Most operators we onboard already suspect they are leaving money on the table with how they handle tips. They usually are. A central London bistro we took on this spring was running £142,000 of card tips and service charge through main payroll. Their 2024/25 employer NIC on that pot alone came to a hair over £19,000. Add the staff side and the team was losing another £11,000 of take-home. That is £30,000 of cash a single 60-cover restaurant was handing to HMRC every year, and nothing in the law required them to.

A correctly structured tronc scheme can remove every penny of that NIC, employer side and employee side both. The Income Tax stays, because tips are still earned income. But the National Insurance disappears. For a UK hospitality business that distributes any meaningful volume of card tips or service charge, this is the single biggest annual saving on the table.

Below is what £100,000 of annual tips actually does on its way to the team. The waterfall traces every deduction in order, then shows where the saving lands once an independent tronc takes over.

The maths is mechanical. Employer NIC sits at 15 percent on earnings above the £5,000 secondary threshold (both increased at the Autumn 2024 Budget and in force from 6 April 2025). Employee NIC sits at 8 percent on earnings between £12,571 and £50,270 for 2025/26. A tronc removes both. Anything you can legitimately move from main payroll into a properly run tronc strips out 23 percent of that pound before it even reaches the team.

What a tronc actually is, in plain English

A tronc is a tip-pooling arrangement that runs alongside your main payroll but is administered independently by a person called the troncmaster. The troncmaster decides who in the team gets what share of the pooled tips, gratuities and service charges. They run a separate PAYE scheme with its own reference number from HMRC. Income Tax is deducted at source through that scheme. National Insurance is not, because the legislation treats tronc distributions as not paid by the employer.

The legal underpinning sits in section 6 of the Social Security Contributions and Benefits Act 1992 and the long-standing HMRC guidance booklet E24 (last refreshed on 1 November 2024). The principle is straightforward: if money is paid to staff by someone other than the employer, and that someone is not influenced by the employer in allocation decisions, then it is not "earnings paid by the employer" for NIC purposes.

That last clause is the entire game. Most failed tronc cases turn on a single point: HMRC concluded that the employer in fact controlled who got what. The label on the bank account did not save them. The intent of the deed did not save them. What HMRC looks at is decision-making in practice.

The four conditions HMRC tests

Before any business banks the saving, HMRC wants to see that the tronc meets four conditions, all of them together, all of the time.

1. Independence of the troncmaster. The person making the allocation decisions must not be the employer, a director, or someone taking instruction from either. A working employee can be the troncmaster (a head waiter or a senior bartender is common). A payroll bureau acting as an independent administrator can be the troncmaster. The owner, the GM acting under owner instruction, or a relative of the owner cannot.
2. Separate PAYE scheme reference. The tronc must operate under its own PAYE reference issued by HMRC. The main payroll keeps wages and salary. The tronc PAYE handles only the pooled tips. Two sets of payslips, two reference numbers, two sets of submissions.
3. Documented allocation rules. The way tips are split must be written down in advance: by hours worked, by role weighting, by service points or any other defensible system. The troncmaster applies the rules consistently. Ad-hoc decisions, especially ones the owner can be shown to have influenced, break the whole structure.
4. Genuine pooled funds. Card tips and service charges go into a tronc account or a tronc-tagged ledger from the till. They do not transit through the trading bank account. The troncmaster pays them out from the pool. Money flowing in and out of the employer's operating account is a red flag.

Get any one of these wrong and the NIC saving evaporates. Worst case, HMRC backdates the assessment to the point the tronc was first claimed and you owe the lot, plus interest and a behaviour-based penalty.

Tipping Act 2024 changed the conversation

The Employment (Allocation of Tips) Act 2023 came into force on 1 October 2024 and reshaped the way the industry handles tips. The act requires every UK employer to pass on 100 percent of qualifying tips, gratuities and service charges to workers, allocate them fairly and transparently, keep written records for three years, and publish a written tipping policy that workers can see. Failure to comply opens the door to employment tribunal claims worth up to £5,000 per worker.

The act and the tronc rules are not the same thing, but they sit side by side neatly. The act tells you how to allocate. The tronc rules tell you how to allocate NIC-free. A compliant tronc with a written allocation policy, signed off by an independent troncmaster, satisfies both regimes at once.

The HMRC update to booklet E24 on 1 November 2024 specifically called out the act and reinforced that independence of the troncmaster is the central test. We have seen HMRC become noticeably more aggressive on enquiry in the 18 months since. Operators who set up loose troncs in the 2010s and never revisited them are now being asked to prove independence in writing. Some cannot.

Card, cash and service charge: which qualify

Not every penny of tip income works the same way for NIC.

Card tips and digital tips. Anything paid by the customer through your card terminal or app, on top of the bill, that the operator distributes to staff is the classic tronc candidate. Routed through a compliant tronc, NIC-free. Routed through main payroll, NIC due both sides.

Service charge (discretionary or compulsory). A discretionary 12.5 percent or 15 percent added to the bill, where the customer can refuse it, behaves the same as card tips for tronc purposes. A compulsory service charge, where the customer cannot remove it, is treated differently in some VAT cases (it can attract VAT) but for NIC it can still flow through a tronc provided the four conditions above are met.

Cash tips kept directly by the server. If a guest hands £10 in cash to the waiter and the waiter pockets it, that is not part of the tronc and is not subject to employer NIC at all. The employee is still required to declare it on their personal tax return. The reason most operators set up a tronc is precisely to clean up this fragmented picture: pool everything, take the NIC saving on the card portion, give the team a transparent and predictable take-home figure each pay cycle.

Tips paid via a third-party platform. The treatment depends on whether the platform pays the employee directly or pays the operator who then distributes. Direct-to-employee payments may sit outside the tronc entirely. Platform-to-operator-to-employee should run through the tronc to capture the NIC saving.

What the saving looks like at three venue sizes

The percentage saving is fixed. The cash saving scales with how much of your revenue arrives as tips and service charge.

Figures assume all routed tips fall above the £5,000 employer secondary threshold per employee, with staff in the 8 percent employee NIC band. Income Tax is unchanged across both routes.

What this means for you

If your venue already runs a tronc, the question is whether it would survive an HMRC review today. Three things to check before next quarter:

• Pull the tronc deed and confirm the troncmaster named is still independent in practice. If the GM was named in 2019 and has since become the owner's partner, the deed needs updating.
• Audit the last six months of allocation decisions. Have any been visibly influenced by the owner? Emails, WhatsApp messages and verbal instructions are all evidence in an HMRC enquiry.
• Check the Tipping Act compliance. Written policy in place, three-year records kept, fair allocation method documented. A tribunal claim is a separate exposure from an HMRC enquiry.

If your venue does not yet run a tronc and you handle more than around £40,000 of card tips per year, the case is straightforward. The annual NIC saving covers a fully managed payroll and tronc service many times over, and the team takes home noticeably more on the same gross tip pool.

From a standing start, a clean setup takes 10 to 15 working days: draft deed, appoint and brief the troncmaster, register the separate PAYE scheme with HMRC, update the written tipping policy, configure payroll software to run both schemes in parallel. LOYALS handles all five steps end-to-end as part of our hospitality payroll and PAYE service.
