Short-term rentals owe Baltimore County's Transient Occupancy Tax of 9.5% of the room rate under Article 11, Subtitle 4, Title 4 of the County Code. The STR license application and renewal fee may not be less than $300, and the license runs for a three-year term.
Baltimore County Code 35-6-211 states a short-term rental is subject to the Transient Occupancy Tax under Article 11, Subtitle 4, Title 4 (Sections 11-4-401 through 11-4-406). The County's official rate is 9.5 percent of the room rate. Non-transient occupancy, defined as sleeping accommodations for more than 90 consecutive days, is exempt (Code 11-4-401). Separately, the STR license application fee under 35-6-203, and the renewal fee under 35-6-207, are set by the County Administrative Officer and may not be less than $300; the license expires on its third anniversary unless renewed for another three-year term. Airbnb and similar platforms may collect and remit the transient tax on hosts' behalf.
Failing to levy, collect, remit, or otherwise comply with the transient occupancy tax requirements is grounds to suspend or revoke the STR license, in addition to tax assessments, penalties, and interest.
