The official search
Business records in Maryland are kept by the Maryland State Department of Assessments and Taxation (SDAT), Charter Division. This is the first thing that trips people up: Maryland has a Secretary of State, but that office handles charities, trademarks, and notaries — not business entities. If you are searching a Secretary of State website for a Maryland LLC, you are in the wrong place.

SDAT's database covers the entities registered with the Department — LLCs, corporations, limited partnerships, LLPs, statutory trusts, and similar entities — plus trade names registered with SDAT. Records include entities that are forfeited, inactive, cancelled, merged, or dissolved, not just active ones, so expect to see dead records in your results and read the status on each one.
There is no separate yes-or-no availability tool. You judge availability from the search results, and SDAT makes the final distinguishability decision when your Articles of Organization or name reservation is reviewed.
A results list shows each match's Department ID, entity name, and status. Opening a record is reported to show a general-information view with the legal name, Department ID, entity type, status and good-standing position, formation date, principal office address, resident agent (Maryland's name for a registered agent), and filing history. "Active" and "in good standing" are not the same thing in Maryland — an entity can exist but be out of good standing for a missed annual report. Members and owners are not published as an ownership roster.
Step by step
- Open the Business Entity Search on Maryland Business Express and leave Search by set to Business Name.
- Search your full proposed name without "LLC." Review every result, whatever its entity type — corporations, partnerships, and trade names can all conflict with your name, not just other LLCs.
- Search again on the most distinctive part of the name alone — for example, search "Chesapeake" by itself. This catches near-matches that a full-name search can bury.
- Try spelling and spacing variants of your name. Maryland's test is whether a name is distinguishable on SDAT's records, and small differences may not save a similar name — treat anything close as a conflict until SDAT rules otherwise.
- If you already know a competitor's Department ID, search by Department ID instead to pull up that one record directly. A Department ID is a letter (marking the entity type) followed by eight numbers.
- If nothing close appears, the name is probably available — but only SDAT's review of your filing or reservation is definitive.
Maryland's name rules
The rules are in Title 1, Subtitle 5 of the Corporations and Associations Article of the Maryland Code.
Designator. Under §1-502, the name must include one of: "limited liability company," "L.L.C.," "LLC," "L.C.," or "LC." Maryland is unusual in allowing the short "LC" forms. A benefit LLC must use a "benefit" version of one of these designators instead.
Distinguishable. Under §1-504, your name must be distinguishable upon the records of the Department from:
- The name of any entity organized or authorized to transact business in Maryland
- Any name reserved or registered under Subtitle 5
- The disclosed assumed name adopted by a foreign entity authorized to transact business in Maryland
In practice, do not count on a different designator, punctuation, capitalization, or spacing to make a similar name distinguishable — SDAT decides, and the safe assumption is that the core words have to be different.
Restricted words. Words tied to regulated industries — banking, trust, and insurance wording are the usual examples — may require approval from that industry's regulator before SDAT will accept them. If your name leans on a word like that, check with SDAT's Charter Division before you file.
Reserving a name. Maryland allows name reservations under §1-505 using SDAT's Corporate Name Reservation Application: $25 for 30 days (expedited handling of the reservation adds $20). Thirty days is one of the shortest reservation terms in the country — have your Articles of Organization nearly ready before you reserve, and expect to pay again if you need more time. A reservation is optional; it does not establish an LLC.
What the search can't tell you
- A final verdict. The search gives no availability ruling. SDAT decides when it reviews your Articles of Organization or reservation application.
- Whether an owner is trustworthy or licensed. A record shows registration and standing, not licensing, finances, or reputation.
- Trademarks and domains. The search says nothing about federal or state trademark rights, or .com availability. Note that Maryland state trademarks are handled by the Secretary of State — a different office from SDAT.
- Who owns a company. The public record names the resident agent and principal office, not the LLC's members.
If the name looks available
File Articles of Organization with SDAT's Charter Division, online through Maryland Business Express at egov.maryland.gov/businessexpress, or by mail.
- Cost: $100. SDAT's own form instructions list the Certificate of Organization fee as $100.
- Processing — read this before you plan a launch date: SDAT's instructions put standard, non-expedited review at 6 to 8 weeks. Expedited review costs an additional $50 and brings review down to about 7 to 10 business days; same-day review costs an additional $325 online or $425 for documents delivered to the office. For most founders filing online, the realistic cost is $150 with expedited handling, and the portal may add a service fee at checkout — check the total before you pay.
Ongoing: the Annual Report & Business Personal Property Return (Form 1).
- Fee: $300 per year for an LLC — three times the formation fee, every year, even if your LLC owns no property, made no money, and did nothing. (SDAT-certified family farms pay $100.)
- Due date: April 15 every year — one fixed date for every Maryland entity that existed on January 1, not your anniversary month. If April 15 falls on a weekend, the deadline moves to the following Monday. A free 60-day extension, to June 15, can be requested by April 15.
- Late penalty: there is no flat late fee. SDAT assesses an initial penalty of one-tenth of one percent of the county assessment (or a base penalty, if greater), plus interest of 2% of that penalty for each 30 days the return is late. SDAT bills the penalty — do not prepay it.
- If you never file: your LLC falls out of good standing and can be forfeited — and a forfeited entity loses its right to its name. Bringing it back requires Articles of Reinstatement ($100, or $150 expedited) plus every overdue Form 1 and penalty.
FAQ
Is the Maryland LLC name search free? Yes. The Business Entity Search on Maryland Business Express is free and requires no login.
Why isn't this on the Secretary of State's website? Because Maryland assigns business entities to the State Department of Assessments and Taxation (SDAT), not the Secretary of State. The Secretary of State handles charities, state trademarks, and notaries instead.
How much does it cost to form a Maryland LLC? The Articles of Organization filing fee is $100. Expedited review adds $50, and same-day review adds $325 online or $425 in person — SDAT's standard processing time is 6 to 8 weeks.
How long does a Maryland name reservation last? Only 30 days, for a $25 fee under §1-505 — one of the shortest reservation terms of any state.
When is the Maryland LLC annual report due, and what does it cost? Form 1, the combined Annual Report & Business Personal Property Return, is due April 15 every year and costs $300 for an LLC. Missing it leads to penalties, loss of good standing, and eventually forfeiture — including loss of your right to your LLC's name.
