The IRS is restarting its 500 series of balance-due notices to taxpayers after putting a hold on the mailings May 9 due to the COVID-19 pandemic.
While the IRS continued to issue most of its notices, the 500 series was temporarily suspended because of a backlog of mail that built up at the agency due to the pandemic.
The 500 series of balance-due notices includes three different types of notices that warn taxpayers about different stages of nonpayment: the CP501, the CP503 and the CP504. Learn more.
