Frequently asked questions
How is an accounting firm structured?
A modern firm has a Managing Partner at the top with three peer practice leads (Tax, Audit, CAS) plus a Director of Operations. Each practice has its own Manager, Senior, and Staff hierarchy. Total staff usually 5 to 50 for small or mid-sized firms.
What is CAS in an accounting firm chart?
CAS stands for Client Advisory Services, which covers outsourced bookkeeping, controller, and CFO services. CAS is now the fastest-growing practice area at most US firms and usually sits as a peer to Tax and Audit.
How many tax staff per manager?
A healthy ratio is one Tax Manager per 2 to 3 Seniors, with each Senior overseeing 2 to 3 Staff. Below this ratio, work backs up at the Senior level and review quality drops.
