Taxpayers do not need to contact the agency to get this relief as the IRS automatically provides relief based on the address of record with the agency. However, if an affected taxpayer receives a late filing or late payment penalty notice from the IRS that has an original or extended filing, payment, or deposit due date falling within the postponement period, the taxpayer should call the number on the notice or reach out to your Withum Service team to have the penalty abated.
