Due to shortage of resources and processing delays, the IRS is reassigning workers to handle a backlog of unprocessed papers and returns. There are approximately 23.5 million tax returns and other documents that still need to be process from the 2020 tax return season. Some of the delays are due to the IRS checking stimulus payment amounts which is the reason it is important to make sure for the 2021 tax returns to have this information pulled from the IRS site.
