How to Form a Maryland LLP — Step-by-Step

Before anything else, make sure the name you want isn't already taken. Maryland requires your partnership name to be distinguishable from every other business entity on file with SDAT — not just other partnerships, but corporations, LLCs, and reserved names as well. Two names that differ only by punctuation, spacing, or filler words like "the" may not be treated as distinguishable.

Run your proposed name through the Maryland Business Express entity search. Search the exact name and close variations. If something too similar already exists, SDAT can reject your Statement of Qualification, which delays you and, for a professional firm trying to open its doors, can be costly.

Name requirements for a Maryland LLP

• The name generally must include a designator identifying it as a limited liability partnership, such as "LLP," "L.L.P.," "Limited Liability Partnership," or "Registered Limited Liability Partnership."
• It must be distinguishable from all active entity names in SDAT's records.
• It cannot imply a purpose the partnership isn't authorized to pursue, and certain regulated words (such as those implying banking or insurance) may need approval from the relevant Maryland regulator.

If you're not ready to file but want to hold the name, Maryland allows a name reservation through SDAT for a limited period. That step doesn't register the LLP — it just parks the name while you finish the rest.

Maryland uses the term "resident agent" for what many states call a registered agent. You have to name one on the Statement of Qualification, and Maryland requires the agent to consent to the appointment, so decide this before you file.

The resident agent must have a physical Maryland street address (a P.O. box alone won't do) and be available during normal business hours to receive service of process and official state mail on the partnership's behalf.

Who can serve as your resident agent

• A partner or yourself: Any individual partner with a physical Maryland street address who's reliably available during business hours. Note that this address becomes part of the public SDAT record.
• Another Maryland resident: A trusted person with a qualifying in-state address — for example, an attorney who works with the firm.
• A commercial resident agent service: A company authorized to serve as resident agent in Maryland. It keeps its professional address in the public record instead of a partner's home address and ensures someone is always available to accept documents.

Why the choice matters

For a professional partnership, having a lawsuit's summons hand-delivered to the reception desk in front of clients is exactly the scenario a commercial agent avoids. A commercial service also means no partner has to be personally present during business hours, which matters when partners travel to court, job sites, or client meetings.

Registering as an LLP is done by filing a Statement of Qualification (the registration as a limited liability partnership) with the Maryland State Department of Assessments and Taxation, online through Maryland Business Express. This is the filing that converts your general partnership into a registered LLP and turns on the liability shield.

Standard online processing generally runs about two weeks; mailed filings take longer. Maryland offers expedited handling for an additional state charge if you're on a deadline. Check the SDAT fee schedule for the current amounts — we don't quote dollar figures here because your receipt shows exactly what the state charges.

What the Statement of Qualification captures

• Partnership name: Your full name with the required LLP designator.
• Principal office address: The main business address; a P.O. box alone is not sufficient.
• Resident agent name and Maryland street address: The agent's actual physical address, with the agent's consent.
• Nature of the business, where the form calls for it.

What you generally don't have to disclose

You typically don't list every partner's ownership percentage or the internal profit-sharing terms. Those live in your private partnership agreement, not in a public state filing. The Statement of Qualification is a short registration document, not a disclosure of your firm's economics.

The partnership agreement is the internal governing document of your LLP. Maryland does not require you to file it with the state, and you shouldn't — it stays private. But you want it signed before the partnership takes on clients, admits new partners, or opens bank accounts, because it is what turns "some people working together" into a firm with clear rules.

What a solid partnership agreement covers

• Partners and ownership: Who the partners are and each one's ownership interest.
• Capital contributions: What each partner put in at the start and any future contribution obligations.
• Profit and loss allocation: How the firm splits earnings and losses — which does not have to track ownership percentage, though it often does.
• Draws and distributions: When and how partners take money out.
• Management and voting: How decisions get made, what requires unanimous consent, and how day-to-day authority is allocated.
• Admitting and removing partners: The process for bringing in a new partner or handling one who leaves, retires, dies, or is expelled.
• Dissolution and buyout: How the firm winds down or buys out a departing partner's interest.

For a professional practice, the partnership agreement also typically addresses how the LLP's liability shield interacts with each partner's individual professional responsibility. Without an agreement, Maryland's statutory defaults govern all of this, and those defaults rarely match what real partners want.

The IRS hands out a free nine-digit federal tax ID called an Employer Identification Number. A multi-partner LLP always needs one, because a partnership files its own federal return — you can't run an LLP on a single partner's Social Security number.

When an LLP needs an EIN

• Your LLP has two or more partners (essentially always, since a partnership requires at least two).
• You plan to hire employees.
• You want to open a business bank account — banks require an EIN for a partnership.

How to apply

Head to the IRS EIN Assistant on IRS.gov and file the application there. The whole thing runs about ten minutes, and because the EIN comes back on the spot, it's usable the same day. The online application requires a responsible party with a U.S. Social Security number or ITIN. Partners without an ITIN apply by fax or mail using Form SS-4.

Keeping partnership money separate from personal money isn't just good hygiene — it protects the integrity of the entity. Running partnership income through a partner's personal account, or paying personal bills from the firm account, undermines the very separation the LLP relies on.

What most banks want to open an LLP account

• The filed Statement of Qualification from SDAT.
• The IRS EIN confirmation.
• The partnership agreement (many banks ask for it; have it ready either way).
• Government-issued ID for each authorized signer.

Community banks and credit unions are often more flexible with new partnerships than large national chains, and several online business banks can open an account without a branch visit. Compare monthly fees, transaction limits, and minimum balances before committing.

Once you're registered, most of the ongoing work is a single annual filing plus keeping your resident agent current.

Annual Report and Personal Property Return

File the Annual Report with SDAT by April 15 every year — a fixed date, not your registration anniversary. If the LLP owns or leases personal property in Maryland, a Personal Property Return goes with it. Missing the deadline risks losing good standing, which can stop the firm from suing, renewing professional licenses, or securing financing.

Resident agent maintenance

If your resident agent moves, resigns, or you switch providers, update SDAT's records promptly. A stale agent address leaves the LLP technically out of compliance even when everything else is current.

Tax filings

A Maryland LLP files a federal partnership return (Form 1065) and issues Schedule K-1s to the partners, who report their shares on their personal returns. If the LLP sells taxable goods or services or has employees, register with the Comptroller of Maryland for the applicable state taxes. Your CPA should confirm exactly what applies to your practice.
