The national deadline has (mostly) shifted to July, with most state deadlines continuing to follow suit (Virginia, Idaho, and Mississippi are the three exceptions). The increasing gap between year-over-year national averages is not surprising, and is, in fact, a logical outcome. Both firms and their clients are taking advantage of extended tax deadlines.
Two positives in the data are that the percentage of returns not started for 2020 has dropped by nearly 5 points (from 49.1% on 03/24) and that the percentage of returns has increased by 4.2% since 03/24. In progress returns, however, have dropped 3.8% since 03/24.
It remains to be seen if social and physical distancing / working remote affects productivity and completion. I believe that as firms continue to work remotely, we will gain additional insights into how the national leaders are optimizing business processes and harnessing the collective power of automation to serve their customers.
