Name reservation: $25, holds 30 days only (shortest in US). Can extend with new $25 fee. Better to file LLC quickly rather than reserve.

Formation Process

File Articles of Organization with Maryland SDAT. Online filing at egov.maryland.gov/businessexpress or mail to Baltimore.

Required: LLC name, resident agent with MD address, principal office address, management structure, purpose statement, organizer information.

Total formation: $100 filing + $25 name reservation (optional) = $100-125 one-time.

Resident Agent Requirement

Maryland uses "resident agent" (same as registered agent). Must have MD physical address (no PO boxes).

Can use yourself if you have MD address. Professional resident agent: $150-300/year.

Annual Report

Due April 15 every year for ALL Maryland LLCs. $300 fee (one of highest in US).

Unlike most states, Maryland doesn't use formation anniversary. Every LLC files by April 15 regardless of formation date.

Why Same Deadline for Everyone

Maryland aligns LLC annual reports with tax deadline (April 15). Simplifies state processing but creates bottleneck.

LLC formed January 2024 pays first $300 annual report April 2024 (3 months later). LLC formed December 2024 pays April 2025 (4 months later).

Form in January-March to maximize time before first $300 annual report. Avoid forming in November-December (short time to first annual report).

MD vs Other Mid-Atlantic States

Maryland $100 + $300/year vs Delaware $90 + $300/year: Similar costs (both expensive).

Maryland $100 + $300/year vs Virginia $100 + $50/year: VA saves $250/year (massive difference).

DC Metro Access

Maryland LLCs get DC metro area access. Good for government contractors, lobbyists, policy organizations.

Proximity to federal agencies and Capitol Hill valuable for certain industries despite high annual fees.

Tax Considerations

Maryland income tax: 2-5.75% state + up to 3.2% local = 8.95% max combined. Pass-through taxation like all LLCs.

No franchise tax beyond $300 annual report. Sales tax: 6% statewide (no local variations).

Baltimore City Additional Taxes

Baltimore City businesses pay additional city income tax. Adds compliance burden for city-based LLCs.

Consider forming in Baltimore County or other MD counties to avoid city-specific taxes.

Operating Agreement

Not required by MD law but HIGHLY RECOMMENDED for all LLCs.

Maryland courts enforce Operating Agreement provisions. Critical for multi-member LLCs.

Foreign LLC

Out-of-state LLCs doing business in Maryland must register as foreign LLC. $100 filing fee.

Annual report still required: $300/year due April 15 (same as domestic LLCs).

When Foreign Registration Required

Maintaining office in MD, employing MD workers, owning MD real estate, regularly conducting business in state.

Online sales to MD customers typically don't require foreign registration (no physical presence).

Common Mistakes

Forming late in year: LLC formed November 2024 pays $300 annual report April 2025 (5 months later). Better to wait until January 2025.

Missing April 15 deadline: ALL Maryland LLCs due same day creates easy-to-remember but easy-to-miss deadline.

Underestimating annual cost: $300/year is 3x California's $800 when amortized (MD $3,000 over 10 years, CA $8,000).

When MD Makes Sense

Choose Maryland LLC if: Government contractor (DC access critical), biotech/healthcare (Maryland clusters), want strong legal framework despite high cost, operating in Maryland/DC metro.

Best for: Federal contractors, lobbying firms, biotech companies (NIH/FDA proximity), healthcare businesses.

Consider alternatives if: Tight budget (VA saves $250/year), operating primarily in other states, no DC-area benefit.

Biotech & Federal Contracting

Maryland strong in biotech (NIH in Bethesda, Johns Hopkins in Baltimore). Many life sciences startups choose Maryland.

Federal contracting businesses benefit from DC proximity and Maryland's established government-business infrastructure.
