The list of Internal Revenue Service (IRS) forms that can be digitally signed continues to grow. On August 28, 2020, the IRS issued a memorandum indicating that it would accept the use of digital signatures on various IRS forms because of the restrictions involved with the COVID-19 pandemic. In September 2020, it announced the addition of several more forms. Then, on April 15, 2021, the IRS announced it is extending the authorization to a large number of IRS forms until December 31, 2021. The IRS has not specified which digital signature product tax professionals must use but has advised that there are several commercial products available.
