DBA Filing in Maryland: Who Issues It, Cost & Steps
DBA Filing rules in Maryland are written by cities and counties, not by the state legislature — which is exactly why generic advice is useless here. Below: how to identify your issuing office, then the general US process.
Maryland's DBA filing is called a 'Trade Name' and you can register it online in minutes.
Maryland residents who want to operate under a name different from their legal business name file what the state calls a 'Trade Name' (also called 'doing business as' or DBA). You can register and renew Trade Names online through Maryland Business Express, and all online filings are processed as expedited.

“All filings completed online are considered Expedited.”
https://egov.maryland.gov/BusinessExpress/UBD/Create - You can renew a Trade Name online up to 6 months before it expires, as long as it remains in active status and the owner is in good standing.
“Trade Names may be renewed online up to 6 months prior to the lapse date. The original Trade Name must be in active status and the owner(s) of the Trade Name must be in Good Standing.”
https://egov.maryland.gov/BusinessExpress/UBD/Create - A Trade Name is not the same as a trademark-Maryland distinguishes between the two for legal purposes.
“Please note that a Trade Name is not the same as a Trademark.”

Who issues a DBA Filing in Maryland
This is a local permit. It is issued by your city or county, not by the state of Maryland. The state office listed underneath handles a related filing — it does not issue this permit.
- Maryland — the state business-filing office (Secretary of State in most states) (registers business entities)

Where a DBA is filed varies more than almost any other filing on this site — county clerk in many states, the state business-filing office in others.
Finding your local office
Start with the city your address sits in — the relevant department is usually called Planning, Building, Community Development, or Business Licensing. If your address is unincorporated, the county performs that role instead. Calling the main switchboard and asking who handles this is usually faster than searching.
Starting point for anything else in Maryland: the state business portal, https://egov.maryland.gov/BusinessExpress. It is a starting point, not the issuer of this permit.
The general US process
This sequence is the shape the process takes across the US. It is not a list of Maryland requirements, and no step here should be read as one — the issuing office named above sets the actual requirements.
- Step 1: Find out where a DBA is filed where you are. County clerk in many states, the state business-filing office in others, and both in a few.
- Step 2: Search that register for the name you want.
- Step 3: File the statement — often called a fictitious business name or assumed name filing — and pay the fee.
- Step 4: Publish the filing in a newspaper if that jurisdiction requires publication. Several do; most do not.
- Step 5: File the proof of publication where publication was required.
- Step 6: Use the name consistently on marketing, invoices and the bank account.
What varies: county versus state filing, whether publication is required, the fee, and whether the filing expires.
Documents usually asked for
A typical list, not a Maryland checklist.
- Government-issued ID
- Legal business name (if an entity, not sole prop)
- Business address
