Step-by-Step: How to Form an LLC in Maryland

Forming an LLC in Maryland is straightforward when you follow the right sequence. Below is a practical, actionable checklist that walks you through every stage — from naming your company to maintaining ongoing compliance. Follow each step in order, and check off items as you complete them.

Step 1: Choose and Reserve Your LLC Name

Your LLC name is the foundation of your brand and legal identity in the state. Maryland law requires specific elements and prohibits certain words.

• ☐ Ensure your name includes "Limited Liability Company,""LLC," or "L.L.C."
• ☐ Avoid restricted words such as "Bank," "Insurance," "University," or "Federal" without additional licensing or consent
• ☐ Conduct a free Maryland business entity search on the SDAT website to confirm your desired name is available
• ☐ Optionally reserve your name for 30 days by filing a Name Reservation Request ($100 filing fee, online or by mail)
• ☐ Consider securing a matching domain name and social media handles before finalizing

Step 2: Appoint a Registered Agent

Maryland requires every LLC to designate a registered agent — a person or business entity authorized to receive legal documents, tax notices, and service of process on behalf of the company.

• ☐ The registered agent must have a physical street address in Maryland (PO Boxes are not acceptable)
• ☐ The agent must be available during normal business hours to accept service of process
• ☐ You may serve as your own registered agent, appoint a trusted individual, or hire a professional registered agent service
• ☐ Professional registered agent services typically cost between $50 and $300 per year
• ☐ If using a service, ensure they offer mail scanning and forwarding so you never miss important correspondence

Step 3: File the Articles of Organization

The Articles of Organization (called a "Declaration of Formation" in Maryland) is the formal document that creates your LLC in the eyes of the state. This is filed with the Maryland Department of Assessments and Taxation (SDAT).

• ☐ Include the LLC's legal name and principal office address
• ☐ Provide the registered agent's name and Maryland street address
• ☐ List the name and address of at least one organizer
• ☐ Specify whether the LLC will be manager-managed or member-managed
• ☐ File online via the SDAT OneStop portal for the fastest processing, or mail the paper form
• ☐ Pay the $100 online filing fee (or $120 by mail)
• ☐ Save your confirmation receipt and the stamped copy of the Articles for your records

Step 4: Create an Operating Agreement

While Maryland does not legally require an operating agreement, forming one is one of the smartest moves you can make as a new LLC owner. This document outlines the internal rules and responsibilities that govern your company.

• ☐ Define member ownership percentages and capital contributions
• ☐ Establish voting rights and decision-making procedures
• ☐ Set profit and loss distribution terms
• ☐ Outline procedures for adding or removing members
• ☐ Include buy-sell provisions and dissolution terms
• ☐ Have all members sign and date the agreement; keep it with your corporate records
• ☐ Update the agreement whenever significant changes occur in ownership or management

Step 5: Obtain an EIN from the IRS

An Employer Identification Number (EIN) is a federal tax ID assigned by the Internal Revenue Service. You need one to open a business bank account, hire employees, and file business taxes — even if your LLC has no employees.

• ☐ Apply for free at IRS.gov — there is no charge
• ☐ Online applications are processed immediately; you receive your EIN instantly
• ☐ Alternative methods include fax (4 business days) or mail (approximately 4 weeks)
• ☐ Write down your EIN and store it securely alongside your formation documents
• ☐ If you have no employees and are a single-member LLC, you may use your SSN instead — but an EIN provides better privacy and separation

Step 6: Register for Maryland State Taxes and Licenses

Depending on your business activities, location, and industry, you may need to register for state tax accounts and obtain local or professional licenses before you can legally operate.

• ☐ Register for corporate franchise tax with SDAT if your LLC is taxed as a corporation
• ☐ Apply for a <
