How to Start an LLC in Maryland
Forming a limited liability company in Maryland is straightforward once you know what the State Department of Assessments and Taxation (SDAT) actually requires. The state filing fee is $100, standard processing runs 7-10 business days, and Maryland is one of the more affordable states to form an LLC with one of the steeper annual maintenance costs in the country. This page walks through every step, the real costs involved, and where we fit in.
What a Maryland LLC Is (and Why People Form One)
An LLC — limited liability company — is a business entity registered with the State Department of Assessments and Taxation (SDAT) that separates your personal assets from your business liabilities. If the business gets sued or runs into debt, your personal bank account, home, and other assets are generally protected, as long as you've kept the LLC and your personal finances properly separated.
In Maryland, LLCs are the most common entity type for small businesses, freelancers, real estate investors, and side-hustle operators. They give you liability protection without the paperwork and governance overhead of a corporation. Taxes pass through to the owners' personal returns by default, which keeps things simple.
The Cost to Form a Maryland LLC
Here's the straight money breakdown:
- State filing fee: $100 (paid to the State Department of Assessments and Taxation (SDAT) when you file the Articles of Organization)
- Annual report fee: $300 (filed annually)
- Resident Agent service: Required. Included in your first year with our formation package.
- Expedited processing (optional): $50
Important Maryland-specific notes: Filing fee: $100 by mail, $150 online through Maryland Business Express. Annual report (Personal Property Tax Return) is $300 due April 15. Filed with SDAT (Dept. of Assessments and Taxation), not Secretary of State. $100 fee for SDAT-certified family farms.
Maryland charges $300 per year for the annual report. Missing the deadline typically leads to late fees and eventually administrative dissolution if the filing isn't brought current.
Step-by-Step: Forming Your Maryland LLC
1. Pick a Name That Meets Maryland Rules
Your LLC name needs to include "Limited Liability Company," "LLC," or "L.L.C." somewhere in it. It also has to be distinguishable from every other business name already on file with the State Department of Assessments and Taxation (SDAT). Before you get attached to a name, search the state's business entity database to make sure it's available.
Avoid anything that suggests your LLC is a bank, insurance company, or government agency unless you actually are one — Maryland (and every other state) takes that seriously.
2. Appoint a Resident Agent
Maryland requires every LLC to have a resident agent with a physical street address in the state. This person or company accepts legal documents, tax notices, and official correspondence on behalf of your LLC. You'll list the resident agent name and address on your Articles of Organization, and that address goes on the public record.
Maryland does not let you serve as your own resident agent in the traditional sense — the state sets specific rules about who can act in that role. A professional resident agent satisfies those requirements while also keeping your address off public records.
3. File Articles of Organization with the State Department of Assessments and Taxation (SDAT)
This is the actual formation step. You file Articles of Organization — sometimes called a Certificate of Formation — with the State Department of Assessments and Taxation (SDAT) and pay the $100 filing fee. The document includes your LLC name, principal address, resident agent name and address, management structure (member-managed or manager-managed), and the names of organizers.
Most states now offer online filing through the State Department of Assessments and Taxation (SDAT) website (https://dat.maryland.gov/). Online filing is faster and usually a few dollars cheaper than mailing paper.
Standard processing in Maryland takes approximately 7-10 business days. Need it faster? Expedited processing costs $50 and typically drops the turnaround to Same day.
4. Create an Operating Agreement
Maryland does not require you to file an operating agreement with the state, but you should absolutely have one. It's the internal rulebook for your LLC: who owns what percentage, how profits are split, how decisions get made, what happens if a member wants out. Banks will often ask for it when you open a business account. Courts look at it if there's ever a dispute. And if you don't have one, Maryland's default rules apply — which may or may not match what you actually want.
5. Get an EIN from the IRS
An Employer Identification Number (EIN) is the federal tax ID for your LLC. You need one to open a business bank account, hire employees, and file federal taxes. It's free to get — apply directly at IRS.gov and you'll typically receive your EIN immediately.
Never pay a third-party service to get you an EIN. The IRS application takes about ten minutes.
6. Stay Compliant After Formation
Forming the LLC is just the start. To keep it in good standing with the State Department of Assessments and Taxation (SDAT), you need to:
- Maintain a resident agent with a Maryland address at all times
- File the annual report on time (every year)
- Keep business finances separated from personal finances (separate bank account, separate records)
- Handle federal and state tax obligations
Miss the resident agent requirement or skip the annual report, and the State Department of Assessments and Taxation (SDAT) can administratively dissolve the LLC. You lose the liability protection until you bring things current.
