The partner-hour math of busy season

Mid-size firms don’t have a prep problem. They have a partner-hour problem. Prep is scalable — hire more seniors, use offshore, lean on associates. Partner review is not. Only a partner can sign the return, and March has a fixed number of hours.

Here is the math we draw on a napkin when a firm asks us to explain the value we think we deliver.

• A mid-size firm might sign 1,500 returns in a busy season.
• Partner review time per return averages 30–60 minutes, depending on complexity.
• That is 750–1,500 partner-hours of review in a compressed ten-week window.
• A 20% reduction in per-return review time returns 150–300 partner-hours to the firm.
• A 30% reduction returns 225–450.

What does a firm do with 200 partner-hours? Depends on the firm. Some firms would take it as shorter weeks during the crunch. Some would take it as more advisory revenue. Some would take it as more careful review of the hardest returns, catching things that would otherwise slip. All three are legitimate answers. The point is the capacity comes back to the firm to allocate.

We measure the same number your firm measures: partner-hours per return, against your own pre-engagement baseline.

We haven’t hit these numbers with every firm. We won’t claim a 30% reduction on the home page until pilot engagements produce it. But this is the shape of the economics, and this is how we think about whether a pilot is earning its keep. If per-return review time isn’t moving, we aren’t delivering, and the pilot is telling us something.
