Payroll CPD for Accountants — IR35, Auto Enrolment and RTI Guide 2026

Payroll is a critical function in every organisation, and the rules governing it — from tax and National Insurance to areas like IR35 and pension auto-enrolment — are detailed and frequently updated. For accountants and finance professionals involved in payroll, keeping knowledge current through CPD is essential. This guide explains why payroll CPD matters, what it should cover, and how to approach it. For related material, see our guide on continuing professional development. Always check current official guidance, as payroll rules, rates and thresholds change.

Why payroll CPD matters

Payroll sits at the intersection of tax, employment and regulation, and the rules are both complex and frequently changing. Tax rates, thresholds, National Insurance, pension auto-enrolment requirements, and rules such as IR35 / off-payroll working are all subject to change, often at least annually. Getting payroll wrong can have real consequences — for employees, for compliance, and for the organisation. This means anyone responsible for payroll needs to keep their knowledge current and accurate. CPD is how payroll and finance professionals stay on top of the rules and apply them correctly. It protects employees and employers by ensuring payroll is handled properly, and it maintains the competence expected of professionals in this area. In a field where the details matter and the rules keep moving, ongoing learning is fundamental to doing the job well.

What payroll CPD should cover

Effective payroll CPD typically spans a range of areas, which may include:

• Tax and National Insurance — the core deductions, and changes to rates and thresholds.
• IR35 / off-payroll working — the rules affecting how some workers are taxed.
• Pension auto-enrolment — the requirements around enrolling employees into pensions.
• Statutory payments — such as statutory sick, maternity and other payments.
• Compliance and reporting — payroll reporting requirements and deadlines.
• Changes and updates — keeping abreast of the frequent changes in this area.

The right focus depends on your role and the payrolls you handle, but the common thread is staying current and accurate across the relevant rules. Always check current official guidance for the precise rules, rates and thresholds, as these are the authoritative source and change regularly.

The complexity of payroll

Part of what makes payroll CPD so valuable is that payroll is genuinely complex. While the basic idea — paying employees correctly and making the right deductions — sounds simple, the practical reality involves many detailed rules. There are different rates and thresholds for tax and National Insurance, rules for various statutory payments, requirements around pensions, and areas like IR35 that require careful judgement about a worker's status. Different situations — from different types of employee to particular circumstances — can bring their own complications. And because so much of this is tied to legislation that changes regularly, what was correct last year may not be correct now. This combination of detail and constant change means that even experienced payroll professionals need to keep learning, which is exactly why ongoing CPD in this area is so important.

How to approach payroll CPD effectively

A practical approach makes payroll CPD both manageable and useful. Stay on top of changes, particularly around the start of new tax years and when significant updates are announced, since this is when much changes. Focus on the areas relevant to your work, prioritising the rules and situations you actually deal with. Build solid foundations in the core areas, since strong fundamentals make the detail easier to handle. Use a mix of learning, from structured courses to keeping up with official updates and guidance. Pay attention to complex areas like IR35 and auto-enrolment, where errors are easy to make. And keep good records of your CPD for your professional body and your own development. Treating payroll CPD as an ongoing part of professional life ensures you stay accurate and compliant in this detailed, fast-moving area.
