Maryland LLC Formation: Requirements & Step-by-Step Guide
To form an LLC in Maryland, you must search for a name, appoint a registered agent, file Articles of Organization with the Maryland Department of Assessments and Taxation (SDAT), get an EIN from the IRS, and draft an Operating Agreement. The state filing fee is $100, and SDAT handles all entity filings.
Quick Answer: Forming an LLC in Maryland
Maryland LLCs are governed by the Maryland Corporations and Associations Article, Title 4A (the Maryland Limited Liability Company Act). The Maryland Department of Assessments and Taxation (SDAT) is the agency for formation, annual reports, and good-standing certificates.
The process includes:
- Confirming your business name is available using the SDAT business entity search.
- Appointing a Maryland registered agent with a physical in-state address.
- Filing Articles of Organization with SDAT (online or by mail).
- Obtaining an EIN from the IRS.
- Drafting an Operating Agreement (not legally required, but critical in practice).
- Filing your first Annual Report with SDAT by April 15 of the year following formation.
An LLC provides members personal liability protection, shielding personal assets from business debts and lawsuits. LLCs are flexible regarding taxes. Single-member LLCs default to disregarded entity status. Multi-member LLCs default to partnership treatment. Either type can elect corporate taxation if desired.
SDAT's online portal (Maryland Business Express) handles most of this. Their main office is at 301 W. Preston Street, Baltimore, MD 21201.
Step-by-Step Guide to Forming Your Maryland LLC
Step 1: Search and Reserve Your Business Name
Before filing, confirm your desired name is not already taken. Use the SDAT business entity search at businessexpress.maryland.gov. The free search shows active and inactive entities.
Maryland allows name reservation before filing. File a Name Reservation application with SDAT. The reservation holds the name for 30 days (Maryland Corporations and Associations Article, § 4A-208).
Step 2: Appoint a Maryland Registered Agent
Every Maryland LLC must continuously maintain a registered agent in the state (Maryland Corporations and Associations Article, § 4A-209). This agent receives legal documents, service of process, and official state correspondence for your LLC.
Your registered agent must:
- Have a physical street address in Maryland (no P.O. boxes).
- Be available during normal business hours.
- Be either a Maryland resident individual or a business entity authorized to do business in Maryland.
Owners with a Maryland street address can serve as their own agent. However, many use a commercial registered agent service for privacy and reliability.
Step 3: File Articles of Organization with SDAT
This document legally creates your LLC. File it with SDAT either online through Maryland Business Express or by mailing a paper form to SDAT's Charter Division.
The Articles of Organization must include (Maryland Corporations and Associations Article, Title 4A):
- The LLC's name (including the required designator).
- The name and address of the registered agent.
- The purpose of the LLC (a general statement is acceptable).
- The address of the LLC's principal office.
- The name and address of each organizer.
SDAT does not require listing members or managers in the Articles, keeping this information off the public record.
Step 4: Obtain an EIN from the IRS
After SDAT approves your Articles, obtain your Employer Identification Number (EIN) from the IRS. The fastest method is the IRS online application at irs.gov, which provides an immediate EIN. You can also apply by fax using IRS Form
