To start a Maryland LLC, file Articles of Organization with the State Department of Assessments and Taxation (SDAT) for a $100 base filing fee, appoint a Maryland resident agent, get a federal EIN, and then file a combined Annual Report and Personal Property Tax Return every April 15 to keep the company in good standing. The rest is detail, but the details are where new owners stumble.
Pick a Name That Clears Maryland’s Rules
Your name has to include one of these designators: “Limited Liability Company,” “L.L.C.,” “LLC,” “L.C.,” or “LC.”1Maryland General Assembly. Maryland Code Corporations and Associations 1-502 – Requirements It also has to be distinguishable from every other entity already on record. A name that differs from an existing one only by punctuation or a suffix like “Inc.” will not pass.
Run your candidate name through the Maryland Business Express name search before you file.2Maryland Business Express. Select a Business Name Confirming availability up front spares you a rejected filing and a lost fee.
Appoint a Resident Agent
Every Maryland LLC needs a resident agent to receive legal documents and official state correspondence. The agent must be either an individual who is a Maryland citizen and at least 18 years old, or a corporation authorized to do business in the state.3Maryland General Assembly. Maryland Code Corporations and Associations 1-401 The agent must have a physical street address in Maryland. P.O. boxes do not qualify.
You can serve as your own resident agent if you have a stable Maryland address and do not mind your name and address appearing in the public record. If privacy matters, or you would rather not stay available at a fixed address during business hours, commercial resident agent services handle the role for a yearly fee, typically starting around $50.
File the Articles of Organization
The Articles of Organization (Form LLC-1) is what legally creates the LLC. The form asks for:
- The full LLC name, with its designator.
- A short purpose statement. Maryland accepts broad language and does not require elaborate detail.4Maryland Department of Assessments and Taxation. Articles of Organization
- The principal office address. Maryland law requires every LLC to maintain a principal office within the state.5Justia. Maryland Code Corporations and Associations 4A-210
- The resident agent’s name and Maryland street address.
- The organizer’s name and address.
The organizer does not have to be a future member. An attorney, a resident agent service, or any other adult can sign and file for you, which some owners prefer so their personal information stays off the public filing. When a non-member acts as organizer, they should later provide a statement confirming control has passed to the actual members.
Fees and Processing Times
You can file the Articles online through the Maryland Business Express portal or by mailing paper documents to SDAT in Baltimore.6Maryland Business Express.

SDAT Corporate Charter Fee Schedule Same-day processing is $325 online or $425 hand-delivered. Once SDAT accepts the filing, you receive an acknowledgment confirming the LLC exists. Certified copies for banks or licensing agencies cost $20 plus $1 per page.4Maryland Department of Assessments and Taxation. Articles of Organization
Get an EIN and Register for State Taxes
Once the LLC exists on paper, apply to the IRS for a federal Employer Identification Number. Banks require it to open a business account, and the IRS charges nothing.9Internal Revenue Service. Get an Employer Identification Number The online application has to be completed in one session because it cannot be saved.
Default federal tax treatment depends on ownership. A single-member LLC is a “disregarded entity,” so income flows through to your personal return. A multi-member LLC is taxed as a partnership.10eCFR. 26 CFR 301.7701-3 – Classification of Certain Business Entities Either can elect S-corp or C-corp treatment by filing the right IRS form. Talk to an accountant before making that election.
State tax registrations depend on what the business does. Hiring employees means registering for unemployment insurance with the Maryland Department of Labor and setting up a withholding tax account with the Comptroller. Selling physical goods means getting a sales and use tax license. The Comptroller’s Combined Registration Application handles multiple state tax accounts in one filing.11Maryland Business Express.

Write an Operating Agreement
Maryland does not require a written operating agreement, but the state’s LLC statute assumes one exists. The law gives “maximum effect to the principles of freedom of contract and to the enforceability of operating agreements,” meaning courts will generally enforce whatever the members agreed to.12Maryland General Assembly. Maryland Code Corporations and Associations 4A-402 Without an agreement, you are stuck with the statutory defaults, which may not match how you actually want to run the company.
Even single-member LLCs benefit. A written agreement helps show the business is a separate legal entity rather than a personal alter ego, which matters if a creditor ever tries to pierce the corporate veil and hold you personally liable. At minimum, the agreement should address how profits and losses are split, what happens when a member leaves or transfers an interest, how major decisions are made and what vote threshold they require, and what triggers dissolution. Multi-member LLCs should be especially explicit, because co-owner disputes are where missing terms cause the most damage.
File the Annual Report and Personal Property Tax Return
Every Maryland LLC must file a combined Annual Report and Personal Property Tax Return (Form 1) with SDAT by April 15 each year.13Maryland Department of Assessments and Taxation. 2026 Form 1 Annual Report and Business Personal Property Return The requirement applies whether or not the LLC earned income or owns any property. The form updates the state on your address, resident agent, and any business personal property in Maryland.
If your Maryland business personal property has an original cost under $20,000, it is exempt from the personal property tax. You still have to file Form 1 anyway. Skipping the filing because nothing is owed is one of the most common mistakes and can lead to penalties and eventually forfeiture. You can file electronically through Maryland Business Express or by mail.14Maryland Department of Assessments and Taxation. Businesses in Maryland
Good standing matters for practical reasons: business loans, professional license renewals, and the right to bring lawsuits in Maryland courts all depend on it.
Late Filing and Forfeiture
Missing the April 15 deadline triggers a penalty of one-tenth of one percent of the county assessment on your personal property, plus interest at two percent of that penalty for every 30 days (or partial 30-day period) the return remains late.13Maryland Department of Assessments and Taxation. 2026 Form 1 Annual Report and Business Personal Property Return Do not try to prepay a penalty you expect. SDAT will bill for anything owed.
Not filing at all is worse. SDAT will send a forfeiture notice, and the forfeiture process runs automatically from there.15Maryland Department of Assessments and Taxation. Frequently Asked Forfeiture Questions Non-filers get estimated assessments at twice the estimated value of their personal property. Forfeiture also strips the LLC’s legal right to do business in Maryland, so it cannot enter contracts, sue, or rely on the liability shield you formed it to provide.
Reinstating a Forfeited LLC
Reinstatement is possible but takes more than filing the overdue report. Start by checking whether the LLC owes back annual reports or personal property taxes. If it ever reported owning personal property, you will need to pay the outstanding property tax to the county or city where the property sat and get a tax clearance certificate. SDAT accepts only the certificate, not a payment receipt.16Maryland Department of Assessments and Taxation. Articles or Certificate of Reinstatement
With the tax side resolved, submit the Articles of Reinstatement along with every delinquent annual report. Standard processing (6 to 8 weeks) costs $100; expedited processing (7 to 10 business days) is $150.16Maryland Department of Assessments and Taxation. Articles or Certificate of Reinstatement Same-day online service adds $325. If another business took your LLC’s name while it was forfeited, you may have to choose a new one to complete reinstatement, so waiting only compounds the problem.
Federal Beneficial Ownership Reporting
The Corporate Transparency Act originally required most domestic LLCs to file beneficial ownership information with FinCEN. As of March 26, 2025, all entities created in the United States are exempt. The requirement now applies only to foreign entities registered to do business in a U.S. state or tribal jurisdiction.17Financial Crimes Enforcement Network. Beneficial Ownership Information Reporting If your Maryland LLC is domestically formed, you do not need to file a BOI report. Older guides and formation services still reference the rule, so it is worth confirming before you spend money on a filing you no longer owe.
