- The Comptroller's temporary-license page (services.marylandcomptroller.gov) loads its content by script, so the 30-day license details (email Templicense@marylandtaxes.gov, 410-767-1543 or 410-767-5462) were taken from the state hub's earlier read; Business Tax Tip #14 gives the Special Events Section number as 410-767-1540, so confirm the phone number before relying on it.
