Is the IRS deleting old e-file 990s?

During the April 2020 update, almost two thousand filings disappeared.

The IRS deleted 1,975 filings from the AWS e-file repository in April. However, you can download the missing filings from the Internet Archive.

April, 2020: Alarm bells ring

By April 2020, I was starting to get worried: the IRS, which had previously been uploading new e-files monthly, had not uploaded anything since December. Imagine my relief, therefore, when I saw that new data had finally become available.

My relief was short-lived when the open-source data enrichment system that powers all our datasets and APIs began reporting missing filings. Was the IRS deleting e-files?

The missing filings all seemed very old. Perhaps, I thought, the IRS was purging filings past a certain age. That was a very disturbing premise, as the older data is a goldmine for academic researchers exploring historical trends in both the tax-exempt sector and the U.S. economy more broadly.

Like basically everyone else in the US, neither Heather Kugelmass nor I had much time to look into it that month, busy as we were with rearranging our lives to cope with the COVID-19 crisis. So we worked with the data we had and planned to revisit the issue when the next update came.

And then it stopped

The IRS finally provided a data update on or around July 28, 2020. Anticipating a huge batch of deletions, I modified my pipeline to detect and report any filings that had been deleted. I ran the code, and initially thought that I must have made a mistake: no new deletions were reported. But I had tested my code very thoroughly, and the filings deleted during the previous update were still missing.

To muddy the waters further, the missing filings turned out not to be the oldest filings on record. In fact, all of the deleted filings from April had been filed with the IRS during calendar year 2011. The oldest filings in the e-file dataset were filed in calendar year 2010. So it didn’t seem to be a rolling deletion process like I initially suspected.

I resisted the urge to analyze the deleted data further, since I still had it in my own archives. However, I am curious what caused the deletion. If anyone else wishes to perform a more thorough analysis, the list of deleted filings can be found here.

Where to find the missing filings

The Internet Archive (of Wayback Machine fame) has been downloading and preserving the e-files since they first became available. While the AWS downloads are far faster and allow you to cherry-pick individual filings, you can get whatever you need here.

All of the missing filings can be found in the 2011 archive. The file is just over 1GB and will take 2+ hours to download due to bandwidth limitations at the Internet Archive.
