How to Start a Maryland Corporation — Step by Step

Before anything else, make sure the name you want is not already taken and that it meets Maryland's rules. A corporate name must be distinguishable from every other entity already on file with SDAT — not just other corporations, but LLCs, partnerships, and reserved names too. Two names that differ only by punctuation, an added "the," or a switch between "and" and "&" may not be treated as distinct.

Search your proposed name using the Maryland Business Express entity search. Try the exact name and close variants. If a similar name already exists, SDAT can reject your Articles, which sends you back to the start.

Corporate naming rules

• The name must contain a corporate identifier: "Corporation," "Incorporated," "Company," "Limited," or an abbreviation such as "Corp.," "Inc.," "Co.," or "Ltd." Note that "Company" or "Co." alone can be ambiguous, so most incorporators use "Inc." or "Corp." to be unmistakable.
• The name cannot imply a purpose the corporation is not authorized to pursue, and words like "bank," "trust," or "insurance" require approval from the relevant Maryland regulator.
• It must be distinguishable on SDAT's records from all active entities.

Optional name reservation

If you are not ready to file but want to hold the name, Maryland lets you reserve a corporate name with SDAT for a set period. This does not create the corporation — it simply parks the name while you finish organizing.

Maryland calls the required point of contact a resident agent — the same idea other states call a registered agent. Every Maryland corporation must name and continuously maintain a resident agent, and that agent must consent to the appointment. Maryland law expressly requires the resident agent's agreement to serve; you cannot simply list someone without their consent.

The resident agent must have a physical street address in Maryland (a P.O. box is not acceptable) and be available during ordinary business hours to accept service of process and official state mail on the corporation's behalf.

Who can be your resident agent

• An individual Maryland resident, such as a director, an officer, or a trusted person with a Maryland street address.
• A Maryland corporation authorized to act as a resident agent, including a commercial resident agent service.

Why the choice matters

Whatever address you list becomes part of the public SDAT record and is searchable by anyone. If you use your home address, it is exposed. A commercial resident agent service keeps a professional address on the record instead, guarantees availability during business hours, and forwards documents to you promptly. For a corporation that may face lawsuits or regulatory contact, reliable receipt of legal process is not a minor detail.

The Articles of Incorporation is the document that legally creates your corporation. In Maryland it is filed with SDAT, not a secretary of state, through Maryland Business Express. This is the single most important filing in the whole process.

What the Articles must include

• Corporate name with its required identifier (Inc., Corp., and so on).
• Purpose — Maryland accepts a broad, general-purpose statement, so you do not need to lock yourself into one line of business.
• Resident agent name and Maryland street address, with the agent's consent.
• Principal office address in Maryland.
• Authorized stock — the number of shares the corporation may issue and their par value, if any. This matters for the fee: Maryland's charter fee has a component tied to the amount of authorized stock, so authorizing an enormous number of shares at formation raises the cost with no benefit for most startups.
• Incorporator — the person who signs and submits the Articles. The incorporator does not have to be a shareholder or director.

Fees and processing

Maryland charges a base charter recording fee plus the stock-based component. The receipt card on this page reflects the current state charge for a standard filing. Standard SDAT processing typically runs a couple of weeks; expedited and same-day options are available for an added state fee when you have a deadline. Once approved, the corporation exists as a legal entity and appears in the SDAT database.

Filing the Articles brings the corporation into existence, but it does not organize it. That happens at the organizational meeting, where the incorporator or initial directors take the actions that turn a shell into a functioning company.

What the organizational meeting accomplishes

• Adopt corporate bylaws — the internal rulebook governing how the board and officers operate, how meetings are called, how votes are counted, and how officers are appointed. Bylaws are not filed with SDAT; they are kept in the corporate records.
• Elect the initial board of directors (if the incorporator has not already named them) and appoint officers — at minimum a president, a secretary, and a treasurer, though one person can hold multiple roles.
• Authorize and issue the initial shares of stock to the founding shareholders, recording each issuance in the stock ledger.
• Approve the corporate seal, bank resolutions, and the fiscal year.

Document all of this in written minutes and keep them with the corporate records. For a single-owner corporation, this can be handled in a single written consent, but skipping it entirely undermines the corporate formalities that protect your personal assets.

A corporation always needs an Employer Identification Number, the nine-digit federal tax ID issued free by the IRS. Every corporation must have one — unlike a single-member LLC, a corporation cannot use an owner's Social Security number for its tax identity. You will need the EIN to open a bank account, file corporate tax returns, hire employees, and make an S election.

How to apply

File the application on IRS.gov using the IRS EIN Assistant. The whole thing runs about ten minutes and hands you the number right away, ready to use that same day. The online application requires a US Social Security number or ITIN for the responsible party. Founders without one apply by fax or mail using Form SS-4. If you intend to elect S corporation status, you generally file Form 2553 with the IRS after the EIN is in hand and within the statutory timing window.

Keeping corporate and personal money strictly separate is essential to preserving the liability shield. Commingling funds is one of the fastest ways to let a court disregard the corporation and reach the owner personally.

What a bank typically requires

• Filed Articles of Incorporation from SDAT
• The IRS EIN confirmation letter
• Corporate bylaws and a banking resolution authorizing the account
• Government-issued ID for the authorized signers

Maryland tax registration

Register with the Comptroller of Maryland if the corporation will collect sales and use tax, withhold employee income tax, or owe state corporate income tax. Maryland levies its own corporate income tax, and unlike a pass-through entity, a C corporation files and pays at the entity level. If you plan an S election, coordinate the federal and Maryland treatment with your accountant.

Once the corporation is running, Maryland's compliance load is modest but has a hard edge to it.

Annual Report and Personal Property Return

File this with SDAT by April 15 every year — a fixed date, not your formation anniversary. It keeps the corporation active and reports business personal property. Missing it puts the charter on a path to forfeiture, which dissolves your liability protection.

Corporate recordkeeping

Hold and minute annual meetings of shareholders and directors, keep the stock ledger current, and document major decisions by resolution. These formalities are what separate a real corporation from a paper one in the eyes of a court.

Resident agent maintenance

If your resident agent changes address or resigns, file the change with SDAT promptly. A lapsed or invalid resident agent puts the corporation out of compliance even when the annual report is current.
