Trader's License (or Exhibitor's Affidavit)
The Comptroller's license bureau says a trader's license from the Clerk of the Circuit Court is required, along with a sales tax account, and the license year runs May 1 to April 30.

- Anyone selling goods in Maryland other than a grower or manufacturer. Exhibitors at a show do not need their own trader's license when the show is promoted by an exempt entity the Comptroller lists (for example a church, government agency or volunteer fire department), or when they give the promoter an Exhibitor's Affidavit saying they get under 10 percent of annual income from like goods at the show. Either way they must not have done more than three shows in the previous 365 days.
