IR-2021-16, January 15, 2021, WASHINGTON ― The Internal Revenue Service announced that the nation’s tax season will start on Friday, February 12, 2021, when the tax agency will begin accepting and processing 2020 tax year returns. The February 12th start date for individual tax return filers allows the IRS time to do additional programming and testing of IRS systems following the December 27 tax law changes that provided a second round of Economic Impact Payments and other benefits. This programming work is critical to ensuring IRS systems run smoothly. If the filing season opened without the correct programming in place, then there could be a delay in issuing refunds to taxpayers. These changes ensure that eligible people will receive any remaining stimulus money as a Recovery Rebate Credit when they file their 2020 tax return.
