The Comptroller has informed us that the due date for the first quarterly estimated digital advertising tax payment is extended to Monday, April 18th. The deadline for taxpayers to make this first payment would otherwise have been April 15, 2022. We are not aware of the Maryland Comptroller’s office otherwise publicizing this extension. Taxpayers making the first quarterly estimated tax payment should also be sure to file a completed copy of the Form 600D, Declaration of Estimated Digital Advertising Gross Revenues Tax.
