Filing articles of organization with the State Department of Assessments and Taxation (SDAT) is what legally creates your Maryland LLC. Maryland calls what most states call a "registered agent" a "resident agent," and that distinction matters throughout the filing process. This guide walks through the steps to name your LLC, file with SDAT, and stay compliant with Maryland's annual reporting rules, using the state's terminology and current filing requirements.
Key takeaways
- File articles of organization with SDAT. The filing fee is $100. Standard processing takes 6–8 weeks, while expedited and same-day options cost more.
- Choose a resident agent with a Maryland physical address. The agent must consent to serve, and the agent's name and address become part of the public record.
- Check name availability before filing. The name must be distinguishable from active businesses on file with SDAT and include an approved LLC designator. A $25 reservation can hold a name for 30 days.
- Budget for annual compliance. The annual report is generally due April 15 beginning the year after formation and normally carries a $300 fee. Eligible MarylandSaves employers may qualify for a fee waiver. Extensions are not automatic, so check SDAT’s current Form 1 instructions to see whether one is available for the filing year.
- Complete post-formation requirements. After approval, determine whether you need a federal tax ID, Maryland tax accounts, licenses, permits, workers' compensation coverage, or other insurance.
Step 1: Choose an available Maryland LLC name
Before you can form your LLC in Maryland, you’ll need to choose a business name that is distinguishable from other names on file with SDAT. If SDAT considers your preferred name too similar to an existing name, you’ll need to choose another. Before filing the articles of organization, search for your preferred name and close variations. LegalZoom’s free business name search tool lets you search the names already on file with the Maryland SDAT.

What Maryland LLC naming rules apply?
Maryland has specific rules each LLC must follow when choosing a name. Review each of these requirements before you submit the articles of organization.
- Use an approved designator. You must include “Limited Liability Company,” “LLC,” “L.L.C.,” “L.C.,” or “LC” as part of your name.
- Keep the name consistent with the LLC’s stated business purpose.
- Choose a name that is distinguishable from other entities on file with SDAT.
If SDAT rejects the filing, you can correct and resubmit it within 60 days before another filing fee is required.
A $25 name reservation holds an available name for 30 days. It is optional, but it can help if you are not ready to submit the articles of organization immediately.
When does an LLC need a Maryland trade name?
Your LLC’s legal name is the name on its articles of organization. If it operates under another storefront, product, or shortened name, register that trade name with SDAT before using it in business.
A Maryland trade name registration costs $25 and remains effective for five years; renewal is available during the final six months of that period. Learn more about trade name registration or how to file a Maryland trade name (DBA).
Step 2: Choose a Maryland resident agent
The role that many states refer to as a registered agent is called a resident agent in Maryland. This person or eligible business accepts legal papers and official notices for the LLC at a physical Maryland address.
The resident agent may be an individual who resides in Maryland or a Maryland corporation, LLC, or limited partnership. Every Maryland LLC must designate one on their articles of organization.
The articles of organization require the agent’s name, a physical Maryland address rather than a P.O. box, and the agent’s signed consent to serve. The agent’s name and address become part of the public business record.
Can you serve as your own resident agent?
Yes, if you are an individual who resides in Maryland and can provide a physical Maryland street address. The LLC itself cannot serve as its own resident agent.
However, before agreeing to be your own resident agent, consider whether publishing your address and being available to receive legal papers during business hours fits your situation. A professional service, including LegalZoom’s registered agent service, may help you avoid using your home as the resident-agent address.
Step 3: File Maryland articles of organization with SDAT
Once the name and resident agent are ready, file articles of organization with SDAT to legally create the LLC. Review the current form before submitting because its required fields, signatures, fees, and processing options can change.
What information does the current form ask for?
Maryland’s form is short, but each field has a specific purpose. Here’s what you’ll need to include:
- LLC’s name
- LLC’s purpose (optional)
- Principal office address
- Resident agent name, Maryland street address (no P.O. boxes), and signature
- Signature of an authorized person (usually the filer)
- Return mailing address
Member or manager names are not required in the articles, and including a return mailing address or email helps SDAT contact you if information is missing.
How much does filing cost, and how long does it take?
Standard filing costs $100 and takes an estimated 6–8 weeks. Expedited filing is $150 total and is estimated at 7–14 business days; same-day filing totals $425 online or $525 on paper. Online filings also carry a 3% portal service fee.
Where can you file?
You may file online through Maryland Business Express, by mail, or by hand delivery. If you file with a paper form, you can download it from Maryland’s forms page. Make sure to use the current version and type or print clearly in black ink; hard-to-read submissions may be returned.
| Method | Where | Fee | Turnaround |
|---|---|---|---|
| Online | Maryland Business Express | $100 + 3% portal service fee | Timing depends on the processing option selected |
| SDAT Charter Division, 700 E. Pratt St., Suite 2700, Baltimore, MD 21202 | $100 | 6–8 weeks | |
| In-person/drop box | 123 Market Place, Baltimore, MD 21202 (hand-delivery dropboxes) | $525 | Same-day processing |
Step 4: Create a Maryland LLC operating agreement
Maryland does not require an LLC to have a written operating agreement or file one with SDAT. Even so, a written agreement is extremely useful because it records how the owners will manage the business and can help banks, business partners, and others understand who has authority to act.
A useful agreement can address ownership percentages, contributions, management authority, voting, profit and loss allocations, distributions, transfers, adding or removing members, and dissolution. Even a single-member LLC can use a written agreement to document signing authority and reinforce the separation between the owner and the business. LegalZoom can help you create your LLC operating agreement from a guided questionnaire.
Step 5: Get an EIN
An employer identification number, or EIN, is the LLC’s federal tax identifier. Multi-member LLCs generally need an EIN, as do LLCs with employees or certain federal excise-tax obligations. A single-member LLC without employees or those tax obligations may not need one for federal tax purposes, although a bank or government agency may still request it.
To get an EIN for your LLC, apply directly through IRS.gov at no charge or you can have LegalZoom handle the application on your behalf.
Step 6: Register for applicable Maryland taxes, licenses, and insurance
Formation with SDAT does not automatically register the LLC for every tax account or authorize every business activity. Review the LLC’s sales, payroll, industry, location, and staffing before opening so you complete only the registrations that apply.
When do you register through Maryland Tax Connect?
Use Maryland Tax Connect to complete the combined registration application for accounts that match the LLC’s activities. Have your EIN and SDAT Department ID available when you start.
- Register for sales and use tax if the LLC sells taxable goods or services. Maryland’s general rate is 6%, while certain data, information-technology, and software-publishing services are taxed at 3%.
- Register for employer withholding if the LLC pays wages.
- Register for admissions and amusement tax if the LLC charges covered admission fees or conducts covered amusement activities.
When do you need a trader’s, professional, local, or industry license?
A trader’s license is a common requirement for businesses that sell goods, subject to exceptions such as growers and manufacturers. Professional, occupational, health, alcohol, home-occupation, and other state or local requirements depend on the activity and location; check the Maryland Licensing OneStop Portal and the appropriate county or city office. LegalZoom’s Business License Report can provide a customized list.
When does workers’ compensation apply?
Most Maryland employers with covered employees need workers’ compensation coverage. Statutory exclusions and elections may apply to some workers and owners, so confirm the rule for the LLC’s staffing and ownership before relying on an exception.
How much does it cost to form and maintain a Maryland LLC?
The basic cost is $100 (plus a service fee) to file your articles of organization online. You can choose to pay more for expedited services, and it’s recommended you budget for your first annual report, professional registered agent services, and potentially an attorney or accountant to help with your setup.
How to maintain your Maryland LLC
Keeping the LLC compliant requires more than the initial filing. Track the annual report, any personal property return, resident-agent and office changes, trade-name renewals, licenses, permits, tax accounts, and insurance that apply to the business.
When is Maryland’s annual report due?
Maryland LLCs file a Form 1 annual report with SDAT each year, generally by April 15 beginning the year after formation. The fee is generally $300, although an eligible MarylandSaves employer may qualify for a fee waiver. Extensions are not automatic, so check SDAT’s current Form 1 instructions to see whether one is available for the filing year; see how to file your Maryland LLC’s annual report.
An unresolved annual report or required personal property return can affect the LLC’s good standing and may lead SDAT to forfeit its right to do business in Maryland. Address a missed filing promptly and follow SDAT’s current reinstatement instructions if forfeiture occurs.
When is a personal property return required?
The personal property return is a separate part of Form 1 and does not depend only on whether property originally cost $20,000. SDAT directs an entity to include the return when it owns, leases, or uses personal property in Maryland or maintains a trader’s license. The statewide under-$20,000 rule is a valuation and tax exemption, so separate the filing trigger from whether the property will be valued or taxed.
How do you change a resident agent or principal office?
File SDAT’s resolution to change principal office or resident agent in Maryland Business Express and pay the $25 filing fee. A resident-agent change requires the appropriate business authorization and the new agent’s signed consent; keep the LLC’s contact information current so state notices reach the right person.
Risks of filing a Maryland LLC yourself
Filing a Maryland LLC yourself can be manageable, but several state-specific details are easy to overlook. Review the current SDAT form, confirm the resident agent and address information, and plan for the annual report and any tax or licensing obligations after approval.
- Using the wrong resident-agent eligibility rule can create an avoidable filing problem. Maryland permits an individual who resides in the state or a Maryland corporation, LLC, or limited partnership.
- An incomplete or hard-to-read articles of organization filing can delay formation. Use the current form, complete every required field, and obtain both the authorized-person signature and resident-agent consent.
- Formation does not automatically authorize every business activity. Tax accounts, trader’s or professional licenses, local permits, workers’ compensation, or industry approvals may still apply.

Maryland LLC FAQs
Can I form a Maryland LLC without an attorney?
Yes. Maryland does not require an attorney to submit the articles of organization. Legal advice may be useful when an LLC has multiple owners, complex financing or governance terms, regulated activities, or a dispute about ownership or liability.
When must an LLC formed in another state register in Maryland?
An LLC formed under another state’s law generally must register as a foreign LLC before doing business in Maryland. Whether a particular activity counts as doing business can depend on the facts and statutory exceptions, so review the current SDAT requirements before operating, hiring, or opening a location in Maryland.
Can a Maryland LLC have one owner?
Maryland permits a single-member LLC. It follows the same state formation and annual report process, although its federal tax treatment and EIN requirements can differ from those of a multi-member LLC.
Does Maryland require LLC formation notices to be published?
Maryland does not require a newly formed LLC to publish a formation notice in a newspaper; the LLC is formed when SDAT accepts its articles of organization.
Can someone who lives outside Maryland form a Maryland LLC?
Maryland law allows any person to form an LLC, so members do not have to live in the state. The LLC must still maintain a Maryland principal office and appoint a resident agent with a physical Maryland street address.
Are Maryland LLC owners’ names publicly available?
Not necessarily. Maryland’s standard articles of organization do not require member or manager names. However, the authorized person’s signature and the resident agent’s name and address appear in the public filing, and owner names may appear in other public records.
How is a Maryland LLC taxed?
An LLC’s tax treatment depends on its number of members and any tax elections it makes. For federal income tax purposes, a single-member LLC is generally disregarded and a multi-member LLC is generally treated as a partnership unless the LLC elects corporate treatment. Maryland filing obligations generally follow that classification, while pass-through entity, sales, payroll, and other taxes may also apply.
