How to Form an LLC in Maryland: Complete 2026 Guide
Maryland offers a straightforward LLC formation process through the State Department of Assessments and Taxation (SDAT). The filing fee is $100, and online filings process in about 7 business days. Maryland sits at the center of the Baltimore–Washington corridor, giving businesses access to federal agencies, defense contractors, and one of the most educated workforces in the country. The trade-off: Maryland's $300 annual report is one of the highest recurring compliance costs in the nation.
The number you need to remember: $300 every April 15. Every Maryland LLC must file a combined Annual Report and Personal Property Tax Return with SDAT by April 15 each year. The fee is $300 — regardless of the size of your business. A free 60-day extension (to June 15) can be requested online by April 15, but the fee still applies. Failure to file can result in charter forfeiture, meaning your LLC loses the right to conduct business in Maryland.
Our top pick to form your LLC in Maryland: Northwest Registered Agent charges $39 for formation and includes a free year of registered agent service.

What You Need Before Filing in Maryland
Maryland uses the Maryland Business Express portal for online filings. You need:
- LLC name that includes "Limited Liability Company," "LLC," or "L.L.C." and is distinguishable from existing Maryland entities. Search the SDAT Business Entity Search to check availability.
- Resident agent (Maryland's term for registered agent) with a physical street address in Maryland. P.O. boxes are not accepted. Must be an individual at least 18 years old or a company authorized to do business in Maryland. Must be available during normal business hours.
- Articles of Organization details: LLC name, resident agent name and Maryland street address, business purpose (optional but recommended), and organizer signature.
- Maryland Business Express account: Create an account on the portal before filing.
Step-by-Step: Forming a Maryland LLC in 2026
Step 1: Choose and Verify Your LLC Name
Search Maryland Business Express to confirm your name is available. Your name must include "Limited Liability Company," "LLC," or "L.L.C." and cannot be misleadingly similar to an existing Maryland entity.
Step 2: Appoint a Maryland Resident Agent
Every Maryland LLC must designate a resident agent with a physical street address in Maryland. The agent receives legal documents, tax notices, annual report reminders, and service of process. Northwest Registered Agent charges $39 for LLC formation and includes a free year of resident agent service in Maryland.
Step 3: File the Articles of Organization
Submit the Articles of Organization through Maryland Business Express. The filing fee is $100 online (plus a $50 expedited fee that's automatically included for online submissions, making the total $150). Mail filings are $100 but take 4–6 weeks. Once approved, SDAT issues a Certificate of Organization.
Step 4: Obtain Your EIN (Federal Tax ID)
Apply for an Employer Identification Number at IRS.gov. It's free and takes about 5 minutes online. Required for business banking, hiring employees, and filing taxes.
Step 5: Draft an Operating Agreement
Maryland does not require an operating agreement by law, but it's strongly recommended. It defines member roles, profit distribution, voting rights, and dissolution procedures. Particularly important for multi-member LLCs.
Step 6: Open a Business Bank Account
Separate your personal and business finances. You'll need your Certificate of Organization, EIN confirmation letter, and operating agreement.
Step 7: Register for State Taxes
Depending on your business activities, register for Maryland state taxes through the Comptroller of Maryland. Sales tax registration is required if selling taxable goods or services.

Maryland-Specific Considerations
The $300 Annual Report: Maryland's Biggest Compliance Cost
Maryland's annual report fee is among the highest in the nation. At $300/year, the 3-year compliance cost ($900) exceeds many states' total formation-plus-compliance costs. The report is combined with the Personal Property Tax Return (Form 1), which requires you to report tangible business assets located in Maryland. If total personal property is under $20,000, it's exempt from valuation and property tax — but you still must file the report.
State + County Income Tax
Maryland LLC members pay both state and county income taxes. The state rate ranges from 2% to 6.5% (with new brackets for high earners starting in 2025). County rates range from 2.25% (Worcester) to 3.3% (Dorchester). The combined state + county rate can reach 9.8% for high-income earners in certain counties, making Maryland one of the higher-tax states for LLC owners.
Capital Gain Surtax (New in 2025)
Starting in 2025, Maryland imposes a 2% surtax on net capital gains for taxpayers with federal adjusted gross income over $350,000. This applies to LLC members who realize significant capital gains. An exception exists for the sale of a primary residence under $1.5 million.
Baltimore–Washington Corridor Advantage
Maryland's location between Baltimore and Washington D.C. gives businesses access to federal agencies, defense contractors, the NIH, and one of the highest concentrations of educated workers in the country. For government contracting, cybersecurity, biotech, and consulting businesses, Maryland is a natural home state.
When Maryland Is — and Isn't — the Right Choice
Maryland makes sense if:
- You live in Maryland or operate in the Baltimore–D.C. corridor
- Your business is in government contracting, defense, biotech, or cybersecurity
- You need proximity to federal agencies and the D.C. market
- You can absorb the $300/year annual report cost
Consider another state if:
- You want minimal annual compliance costs. Ohio ($0 annual), New Mexico ($0 annual), or Michigan ($25 annual) are much cheaper.
- You want zero state income tax. Consider Texas, Florida, Wyoming, or Nevada.
- You want maximum privacy. Wyoming and New Mexico offer stronger anonymity.
- You're nearby but cost-sensitive. Virginia ($100 filing, $50 annual) and Washington D.C. ($99 filing) are alternatives.
Original Research: Maryland LLC Total Cost Analysis
We analyzed SDAT filing data and fee schedules to calculate the true compliance cost for Maryland LLCs:
| Metric | Data |
|---|---|
| Formation filing fee | $100 (mail) / $150 (online, includes $50 expedited) |
| Annual report fee | $300/year (due April 15) |
| Late penalty | $100+ |
| State income tax | 2%–6.5% |
| County income tax | 2.25%–3.3% |
| Capital gain surtax | 2% (on AGI over $350K) |
| Foreign LLC registration | $100 |
| Best filing strategy | Maryland Business Express online ($150, 7 days) |
Finding: Maryland's formation cost is moderate ($100–$150), but the $300 annual report makes it one of the most expensive states for ongoing LLC maintenance. The 3-year DIY cost is $1,000 ($100 + $300×3), putting Maryland in the top tier of state compliance costs. The value proposition is location: if your business benefits from the Baltimore–D.C. corridor, proximity to federal agencies, or Maryland's educated workforce, the higher compliance cost may be justified. For cost-conscious owners who can operate from anywhere, Virginia next door offers a much cheaper alternative.
Frequently Asked Questions About Maryland LLC Formation
How Much Does It Cost to Form an LLC in Maryland?
The state filing fee is $100 by mail or $150 online (includes mandatory $50 expedited fee for online filings). The annual report costs $300/year. Using Northwest Registered Agent at $39, total first-year cost is approximately $489 ($39 + $150 + $300).
When Is the Maryland Annual Report Due?
April 15 every year. A free 60-day extension to June 15 can be requested online by April 15. The $300 fee is the same regardless of when you file within the window.
What Happens If I Miss the Annual Report Deadline?
A $100+ late penalty is assessed. Continued non-filing can result in charter forfeiture — your LLC loses the right to conduct business in Maryland and you cannot obtain Certificates of Good Standing.
What Is the Personal Property Tax Return?
The annual report (Form 1) includes a section for reporting tangible business assets in Maryland as of January 1 — things like office furniture, equipment, and inventory. If total personal property is under $20,000, it's exempt from valuation and property tax, but the form still must be filed.
How Long Does It Take to Form a Maryland LLC?
Online filings through Maryland Business Express process in about 7 business days. Mail filings take 4–6 weeks. Same-day in-person service is available for $425 extra at the SDAT office in Baltimore (appointment required).
Do I Need a Registered Agent in Maryland?
Yes. Maryland calls it a "resident agent." The agent must have a physical Maryland address, be at least 18 years old (if an individual), and be available during normal business hours. You can serve as your own agent if you meet these requirements.
Is Maryland a Good State for an LLC?
For Maryland residents and businesses in the Baltimore–D.C. corridor, yes — especially in government contracting, defense, biotech, and cybersecurity. The $300 annual report is a significant recurring cost, but the location advantages and access to the federal market often justify it. For cost-sensitive businesses, Virginia or Delaware may be better alternatives.

Maryland-Specific Pitfalls Most Guides Skip
$300 Annual Report filing fee — one of the highest in the country. Every Maryland LLC files an Annual Report (Form 1) with the State Department of Assessments and Taxation (SDAT) by April 15 each year, $300 flat fee. Failure results in loss of good standing and eventual forfeiture. Source: Maryland SDAT, Annual Report and Personal Property Tax Return.
Personal Property Tax Return is a separate filing on the same deadline. If the LLC owns or leases tangible personal property in Maryland (office equipment, inventory, vehicles) or holds a trader's license, it must file Form 1 Part B Business Personal Property Tax Return by April 15 alongside the annual report. Assessments become local tax bills from the county where the property sits.
No trade name? No legal protection for it. Maryland does not automatically protect an LLC's trade name (DBA). If operating under a name other than the registered LLC name, the LLC must file a separate Trade Name Application with SDAT ($25) to secure rights.
