Tax season does not create staffing problems. It reveals the ones that were there all along. Here are the five mistakes that quietly cost firms the most, and what to do instead.
Mistake 1: Hiring Too Late
Firms that start looking for help in January are already too late — the talent is gone and ramp time eats the season. Capacity planning should start in the fall, when you can still onboard and train someone before the crunch.
Mistake 2: Overloading Senior Staff With Prep Work
When your most expensive, most experienced people spend February keying in 1040s, you are burning margin and risking burnout. Routine preparation should flow to lower-cost capacity so seniors can focus on review, complex returns, and clients.
Mistake 3: Treating Every Return as Equally Urgent
Without triage, simple returns and complex engagements compete for the same attention. Segment work early: standardize the high-volume, low-complexity returns and route them to dedicated preparers.
Mistake 4: Relying on Overtime as a Strategy
Asking a fixed team to simply work more is not a capacity plan — it is a retention risk. The firms with the lowest post-season turnover are the ones that added capacity instead of squeezing their people.
Mistake 5: No Documented Workflow
If onboarding a new preparer means a partner explaining everything verbally, you cannot scale. A documented, repeatable workflow lets you plug in offshore or contract help in days instead of weeks.
The Common Thread
Every one of these mistakes comes down to planning capacity reactively instead of in advance. Firms that treat staffing as a year-round discipline — not a January scramble — run calmer seasons, protect their margins, and keep their best people.
