The IRS announced that some taxpayers may have been erroneously assessed failure to deposit penalties after an IRS system error failed to account for the April 15, 2016, holiday in Washington, D.C. The holiday moved the deadline for payroll tax deposit to April 18, 2016. However, some taxpayers who timely deposited payroll taxes by the later date were assessed failure to deposit penalties. The notice is titled “Your Federal Tax Deposit Wasn’t Submitted Correctly.” At the bottom, the date due is shown as April 15, 2016, and the date received is shown as April 18, 2016. The IRS will contact affected taxpayers and no taxpayer action is required.
