Event permit.
Non-Large Event Permit (private property)
The permit confirms the property can host a temporary event under city zoning. The application needs site, parking, traffic and signage plans, and the city does no inspections itself, though the County Health Department, State Fire Marshal and other outside agencies may. A block party or public-property use is not covered.

Trader's License (or Exhibitor's Affidavit)
The Comptroller says a trader's license from the Clerk of the Circuit Court and a sales tax account are required to sell goods in Maryland, and the license year runs May 1 to April 30. An exhibitor must show the promoter a photocopy of the license or affidavit before the show and display it during the show. Fees are not listed on this page.
- Who
- Vendors
- From
- Clerk of the Circuit Court for Frederick County (statewide rules enforced by the Comptroller's License Bureau)
- When
- 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.
Sales tax.
Temporary Sales and Use Tax License (30 days)
A vendor emails the event date, name and location plus business details to the Comptroller's temporary license desk (or calls 410-767-1543 or 410-767-5462) and collects the 6 percent or 9 percent Maryland sales and use tax, as the Comptroller states. Vendors at three or more events a year should register for a permanent license.
- Who
- Vendors
- From
- Comptroller of Maryland
- When
- Vendors without a permanent Maryland sales and use tax license who sell at one-time events such as craft shows and fairs. Maryland has one statewide rate and no local sales taxes.
- Timing
- Temporary license is valid for 30 days
Flea market and show sales are taxable
The Comptroller's tax tip says flea market sales are taxable like any other sale, a seller must get a license before collecting, and the license must be displayed where sales are made. A 30-day permit is available by phone from the Special Events Section; frequent sellers should get a permanent license through the Combined Registration Application.
- Who
- Vendors
- From
- Comptroller of Maryland
- When
- Vendors at flea markets and similar markets, including private individuals (casual and isolated sales under $1,000 of a seller's own household goods are exempt; dealers and resale goods are not).
What the rules ask of you about vendors.
A show promoter may not let an exhibitor take part unless the exhibitor has given a photocopy of a valid Trader's License or an Exhibitor's Affidavit before the show. Exhibitors must display it, and the promoter must forward all Exhibitor Affidavits to the Comptroller's State License Bureau within seven days after the show. Non-compliance is a misdemeanor with a fine up to $100 or up to 30 days in jail. Official page
