In-house or outsourced: pain-free payroll for your school or trust

School and trust payroll isn’t like payroll anywhere else. Staff hold multiple roles under different contracts, pay scales, and pension schemes – often within the same payslip. There are over 174 pieces of legislation to navigate and more than 80 different pension scheme configurations across the country. And it all needs to work correctly, every month, for around 974,000 people.

For those responsible for payroll in schools and multi-academy trusts, the question is increasingly pressing: should you run school payroll software in-house, or hand it to a specialist managed service?

There’s no single right answer – but there is a perfect fit for your organisation.

Why is school payroll so complex?

Education payroll is uniquely challenging because staff regularly hold multiple roles under different contracts. A music teacher who also serves as a safeguarding lead may be on different pay scales, different terms and conditions, and different pension schemes – yet needs one single payslip. HMRC requires National Insurance and tax reported at employee level, while the Teachers’ Pension Scheme (TPS) requires pension deductions at post level.

With term-time-only contracts paid over 52 weeks, zero-hours supply staff, and TUPE protections when schools join a MAT – leading to staff on different pay dates, different local authority rules, and different pension schemes all running alongside each other – the complexity and risk each month just increases.

What are the benefits of running payroll in-house?

Running payroll in-house using dedicated school payroll software gives you direct control over timelines, data, and query resolution. For trusts with experienced payroll staff and good HR integration it can also be more cost-effective per payslip.

It works well when you have:

• Staff with genuine education payroll expertise – not just general payroll knowledge
• Software built for schools: education pay scales, Burgundy Book, TPS, and LGPS reporting
• Reliable cover if your payroll lead is absent
• Capacity to keep up with HMRC and DfE legislative changes

If all those points are all achievable, in-house is a strong option. If staffing levels are uncertain – and many schools cannot afford to duplicate a specialist role such as payroll – the risks can start to outweigh the benefits of having full control.

“The support from the IRIS team has been fantastic – they’ve gone above and beyond to ensure we have everything we need, resolving any issues promptly. We’re already benefiting from the time savings and the smoother processes.”
– Karren Garrod, HR Lead, Northern Star Academies Trust (NSAT)

When does outsourced payroll for schools make sense?

A managed payroll service handles end-to-end processing, including staff payments, pension submissions, compliance filings – while your team retains full oversight. It eliminates single points of failure and removes the compliance burden from your internal resource. It’s particularly valuable when payroll resource is stretched, errors are recurring, or a growing trust is outpacing the team’s capacity.

It’s important to choose a provider with genuine education expertise, and the relationship quality matters just as much as the technology. Kim Rodwell, School Business Manager at Loughton Manor First School, switched after years of errors and poor support from a previous provider. Her experience with IRIS Payroll Services was transformative:

“I cannot tell you how different things are – the weight that has been lifted from me is huge.”
 – Kim Rodwell, School Business Manager, Loughton Manor First School

What should schools do if their LA is withdrawing payroll support?

Local authority payroll services are under pressure across England, and a number have already withdrawn provision for academies – in some cases with as little as six months’ notice. If your school relies on an LA for payroll, it’s worth reviewing that arrangement now, before a change is forced upon you.

Whether you move to in-house school payroll software or a managed outsourced service, the key is planning the transition carefully: ensuring data migrates cleanly, running a parallel payroll cycle where possible, and choosing a provider with a demonstrable track record in education – one that understands the Burgundy Book and Green Book, TPS, LGPS, and the specific demands of school contracts.

There are no wrong moves – just the right one for you

Both in-house payroll software and managed payroll services are great options. The right choice depends on your team, your trust’s size and complexity, and your capacity to manage compliance. What matters most is making an active, informed decision.

Every Payroll from IRIS supports both options: dedicated school payroll software for teams running payroll in-house, and a fully managed payroll service for those who want specialist support. Either way, it’s built specifically for the demands of education.
