Event permit.
Special Event Permit
The organizer sends the application with a site plan to the Event and Marketing Coordinator, then a planning meeting sets an addendum listing all requirements and fees before the permit is issued. The permittee must contact the sheriff and fire department 30 days before the event, and is responsible for vendors; the county's 2020 manual also requires a sex offender search for vendors and volunteers at county-property events.

The county page says a permit is required only there, but events elsewhere may still need county services such as tent permits, food service permits, sheriff's detail or a road closure. A private event on private property that is not open to the public needs no permit.
- Fee
- $50 application fee (county page); the 2020 manual lists permit fees from $50 (under 100 guests) to $1000 (5001 or more guests) and a $250 refundable deposit for large events
- Timing
- At least 60 days before the event; 6 months for High Impact Events (road closure of 12 hours or more, or 2,000 or more expected)
Vendor and business licenses.
Trader's License (or Exhibitor's Affidavit at a show)
Maryland trader's licenses are issued by the county Circuit Court Clerk (Calvert County clerk: 410-535-1600 ext. 2264) for a May 1 to April 30 license year. The Comptroller says a promoter must collect each exhibitor's trader's license copy or Exhibitor's Affidavit before the show.
- Who
- Vendors
- From
- Clerk of the Circuit Court for Calvert County, for the Comptroller of Maryland
- When
- Anyone selling goods in Maryland who is not a grower or manufacturer. At a show, an exhibitor does not need their own trader's license if the show is promoted by an exempt entity the Comptroller lists, or if they give the promoter an Exhibitor's Affidavit (under 10 percent of annual income from like goods, and no more than three shows in the previous 365 days).
Sales tax.
Temporary Sales and Use Tax License (30 days)
A vendor contacts the Comptroller's temporary license desk with the event date, name and location plus business details, then collects Maryland sales and use tax on event sales. Vendors at three or more events a year should register for a permanent license through Maryland Tax Connect.
- 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.
Flea market sales are taxable (Business Tax Tip #14)
The Comptroller says flea market sales are taxable like any other sale and a vendor must first get a license, either a 30-day permit or a permanent license through the Combined Registration Application. The 6 percent rate is a single statewide rate with no local sales taxes, and vendors must display their license where sales are made.
- Who
- Vendors
- From
- Comptroller of Maryland
- When
- Vendors at flea markets and similar markets, including nonprofits and private individuals (casual and isolated sales under $1,000 of a seller's own household goods are exempt, but not sales by full or part-time dealers)
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
