Maryland’s statute covers a person engaged in a mercantile, trading or manufacturing business as an agent, or doing business under a designation, title or name other than the person’s own name. It requires the certificate before commencing operation. The statute excludes a person who filed a similar certificate with SDAT before July 1, 1991.

Prior to registering the business name of a home improvement company with the Maryland State Department of Assessments and Taxation, an applicant is advised to contact the Home Improvement Commission at 410-230-6171 to ensure a specific name is available. 1. The fee is $25.00. Checks should be payable to: DEPARTMENT OF ASSESSMENTS AND TAXATION Filings submitted in hard copy may be hand delivered to drop boxes that SDAT maintains in the building lobby at 123 Market Place, Baltimore, MD 21202.

Trade name applications must be signed to be accepted. 4. If the name is available and all items on the form are completed, SDAT will accept the filing for record and an acknowledgement, with the filing date will be sent to the “Address of Owner” (unless otherwise stated), ordinarily within 4 weeks of acceptance. 5. This filing is effective for five years from the date of acceptance by SDAT. During the last six months of the period the filing may be renewed for an additional five years. If not renewed, the Department will forfeit the trade name and a new application must be filed. NOTICE: Acceptance of a trade name application does not confer on the owner any greater right to use the name than he otherwise already has. The Department checks the name only against other trade names filed with this Department. Federal trademarks, State service marks, records in other states and trade names are not meant to reserve the name for its owners, to act as a trademark filing or to confer on the owner any greater right to the name than he already possesses. For further information, contact your lawyer, accountant or financial advisor. HOW TO COMPLETE TRADE NAME APPLICATION All blanks on the form must be typed or printed legibly, with black ink, with an original signature (no stamps, photocopies or carbon copy). Numbers correspond to item numbers on the trade name application: 1. TRADE NAME – Only one trade name may appear on this line. To file more than one trade name, complete a separate application for each and send separate checks. No trade name may contain a term that implies it is a type of entity that it is not (i.e., if the owner is an individual, “Inc.” cannot be in the trade name). Check the name on the business data search section of our web site – www.dat.maryland.gov. 2. STREET ADDRESS(ES) WHERE NAME IS USED – List the full address, including street address, city, state and zip code. Post office box number is only accepted when part of the physical address. Out-of-state addresses are acceptable. 3. FULL NAME OF LEGAL ENTITY OR INDIVIDUAL USING THE TRADE NAME – Legal entities may be owners of the trade name. If the legal entity is the owner, the legal entity must be registered with MD Dept of Assessments and Taxation. If there is more than one owner, attach an additional sheet listing each owner with Rev. 08/2026
