K-1 season isn’t what it used to be.
By CPA Trendlines
What was once a defined window during busy season has quietly expanded into a months-long operational challenge—stretching well into summer and fall for many firms.
New data from K1x highlights just how concentrated—and disruptive—the workload has become.

More than 52% of K-1 aggregation work now happens within a three-month window, with over 80% completed within six months. That compression creates a cascading effect: workloads spike unpredictably, timelines shrink under pressure, and teams are forced into reactive mode.
At the same time, delays across the broader K-1 ecosystem—many outside firms’ control—make it nearly impossible to smooth workflows or plan capacity effectively.
The result: A growing mismatch between how firms are structured to work… and how K-1 data actually arrives. That disconnect is becoming one of the defining operational challenges in modern tax practices.
