The IRS Finished the Filing Season with Over 35 Million Tax Returns Awaiting Manual Reviews
“Although most taxpayers successfully filed their returns and received their refunds, a historically high number did not. At the conclusion of the filing season, the IRS faced a backlog of over 35 million individual and business income tax returns that require manual processing – meaning that employee involvement is generally needed before a return can advance to the next stage in the processing pipeline. The backlog includes about 16.8 million paper tax returns waiting to be processed; about 15.8 million returns suspended during processing that require further review; and about 2.7 million amended returns awaiting processing. The backlog resulted largely from the pandemic-related evacuation order that restricted employee access to IRS facilities.”
Other media reports indicate that processing slowness resulted from IRS personnel working on other Covid-related projects such as stimulus payments.
