Tronc audit: find the exposure before HMRC does

Two things changed the risk profile of tronc schemes. The Employment (Allocation of Tips) Act 2024 gave staff a direct route to an employment tribunal over how tips are allocated, and it obliged employers to keep written policies and three years of records. Separately, employer National Insurance rose, which increased the amount at stake in every scheme that turns out not to qualify.

The result is that a scheme which was never really tested can now be challenged from two directions at once: by HMRC over the National Insurance treatment, and by a member of staff over the fairness of the split. The same weak evidence base loses both arguments.

• Troncmaster independence. Who actually decides the allocation? Owner sign-off, informal instructions or a troncmaster who reports to the person setting the split all undermine the exemption the whole structure depends on.
• Employer influence in practice. Rules can look independent on paper while site managers adjust shares week to week. We test the calculations, not the policy document.
• Separation of the PAYE scheme. Tronc distributions paid through the employer's own payroll collapse the distinction the arrangement rests on.
• Deductions from the pool. Card-processing or administration deductions taken from tips have been unlawful since October 2024, not merely unpopular.
• Records and drift. Whether the distribution history, till data and payroll reconcile, and whether the scheme still describes how the business actually operates.

The review works through the arrangement end to end:

1. Governance — appointment of the troncmaster, terms of reference, decision trail.
2. Scheme rules — the points or allocation basis, how new roles and part-timers are handled.
3. Money flow — how card tips and service charge move from the till system to the tronc and out to staff, and whether anything is withheld on the way.
4. PAYE and NIC treatment — the tronc scheme, its returns, and the National Insurance position.
5. Tips Act compliance — written policy, record-keeping, distribution timing and the ability to answer a worker's request for their records.
6. Multi-site consistency — for groups, whether every site does what the group policy says.

A written report you can put in front of a board, an auditor or HMRC. For each finding it states the issue, the evidence, the exposure in cash terms where it can be quantified, and the remedial action — separated into what must be fixed now and what should be tightened over the next quarter. You also get a short summary you can share with staff, because most tip disputes start with people not understanding the rules.

Not every finding is a crisis. A missing written policy is fixed in days. Allocation drift is corrected by rewriting the rules and re-communicating them. The serious cases are the ones where the employer has been directing the split — there, the honest answer is that the scheme has to be rebuilt on a genuinely independent footing, and we will say so rather than paper over it.

You can act on the report yourself, hand it to your accountant, or appoint us as independent troncmaster to run the corrected scheme. The audit is not conditional on the last option.

Operators with a scheme already running who have never had it independently checked; groups that inherited a tronc through an acquisition; finance teams asked by a board or lender to evidence the National Insurance position; and any business that has received a question from HMRC or a formal request for tip records from a member of staff.

If you have no tronc at all yet, an audit is the wrong starting point — read how to set up a tronc scheme instead.

What is a tronc audit?

A tronc audit is an independent review of an existing tip-sharing arrangement against HMRC's requirements and the Employment (Allocation of Tips) Act 2024. It tests whether the troncmaster is genuinely independent, whether the allocation rules are written and applied consistently, whether distributions run through a separate PAYE scheme, and whether the National Insurance position would survive an HMRC challenge.

How far back can HMRC go on a tronc?

Where HMRC concludes that tips were really paid at the employer's direction, it can seek unpaid employer and employee Class 1 National Insurance for earlier years, together with interest and penalties. The number of years depends on whether HMRC treats the position as careless or deliberate, so the cost of a failed scheme is rarely limited to the current year.

What triggers an HMRC review of a tronc scheme?

Common triggers include an employer compliance check on the main PAYE scheme, a staff complaint or tribunal claim about tip allocation, a large or fast-growing tronc relative to payroll, and inconsistencies between till data, the tronc PAYE scheme and the accounts.

How long does a tronc audit take?

For a single site, a review typically completes within a couple of weeks of receiving the scheme rules, recent distribution records and payroll reports. Multi-site groups take longer because each site's practice has to be tested rather than assumed from the group policy.

What do you need from us to run the audit?

The written tronc rules or policy, recent distribution calculations, tronc PAYE records, till or card-tip reports for the same period, and a short conversation with whoever currently acts as troncmaster. Nothing has to be perfect — gaps in that list are themselves a finding.

What happens if the audit finds a problem?

You get a written report setting out each finding, the exposure it creates and the remedial step. Where the scheme can be corrected we set out how, and where the arrangement needs rebuilding we say so plainly. We do not need to be appointed as your troncmaster for the report to be useful.
