How a tronc saves your business 15% employer NIC — the plain English version
Tips paid through a properly-structured tronc are exempt from National Insurance. Here's how the maths works on a typical restaurant tip pool — and what 'properly-structured' actually means.
If your restaurant, hotel, or salon distributes tips through payroll, you're paying National Insurance on them. Your business pays 15% employer NIC. Your staff pay 8% employee NIC. On a tip pool of £20,000 a month, that's £55,200 a year disappearing in tax that doesn't need to.
A properly-structured tronc changes that. Tips distributed through a tronc — run by an independent troncmaster, compliant with HMRC's E24 guidance — are exempt from both employer and employee NIC. The money stays in the room.
What 'properly-structured' actually means
This is where most operators get caught. A tronc isn't just a pot you call a tronc. HMRC's E24 guidance is specific: the tronc must be operated by an independent troncmaster who is genuinely independent of the employer, the employer must not control how tips are allocated, the arrangement must be documented, and the troncmaster must operate a PAYE scheme in their own name.
If any of those conditions aren't met, HMRC can — and does — disallow the NIC exemption and issue a retrospective bill.
The maths on a typical restaurant
Take a venue with a monthly tip pool of £20,000. Run through payroll, the annual NIC cost is £36,000 employer and £19,200 employee — £55,200 combined. Run through a compliant tronc, that cost drops to zero. The NIC saving alone typically covers the cost of the tronc management platform and more.
What Tip4 provides
Tip4 acts as independent troncmaster of record, operates the required PAYE scheme, maintains the audit pack as you go, and handles all HMRC correspondence. You don't need to understand E24 in detail — that's our job.
