Commercial RA cost

~$125/yr

Self-serving as RA places your home address on the public SDAT record. Commercial RA services ($50–$150/yr) preserve privacy and ensure the April 15 Annual Report deadline notices are not missed — critical given MD's $300/yr compliance obligation.

1. Check name availability with the Maryland SDAT Search the Maryland Business Express entity database at businessexpress.maryland.gov to confirm your desired LLC name is available and not deceptively similar to an existing Maryland entity. The name must include a valid LLC designator (LLC, L.L.C., Limited Liability Company, Limited Liability Co., LC, or L.C.) under CA § 4A-202. Optional: reserve the name for 30 days ($25) — Maryland's 30-day reservation is shorter than most states, so act quickly if reserving.
2. Appoint a Maryland registered agent Designate a registered agent with a physical Maryland street address (no PO boxes) who is available during normal business hours. Maryland residents with an MD address may self-serve as RA, but self-serving places your home address on the public SDAT record. Commercial RA services ($50–$150/yr) preserve privacy and ensure legal mail is not missed — especially important given Maryland's mandatory annual report deadline.
3. File Articles of Organization with the Maryland SDAT File online at businessexpress.maryland.gov ($100 fee). Provide: LLC name, registered agent information, LLC purpose, and organizer name and signature. Member names are not required on the Articles of Organization. IMPORTANT: Standard online processing is approximately 4–6 weeks. If time-sensitive, add expedited processing ($50 for 7-day, $425 for same-day) at filing.
4. Draft an Operating Agreement Although not required to be filed with the state, an Operating Agreement governs member rights, profit and loss allocation, voting, and dissolution under CA § 4A-402. Maryland's biotech, healthcare, and defense contractor LLC ecosystem often involves complex multi-member structures — a detailed Operating Agreement is especially critical for Johns Hopkins spin-outs, UMBC research commercialization entities, and defense prime/sub contractor LLCs.
5. Obtain an EIN from the IRS After the Articles of Organization are approved, apply for an EIN at irs.gov/ein. The online application takes under 15 minutes and issues the EIN immediately. Print the EIN Confirmation Letter (CP 575) for bank account opening.
6. Register for Maryland taxes with the Comptroller If the LLC will sell taxable goods or services in Maryland, register for a Maryland Vendor License at marylandtaxes.gov (free). Maryland's 6% state sales tax rate is uniform — no local additions. If the LLC will have Maryland employees, also register for payroll withholding. Maryland's 8.25% corporate income tax applies if the LLC elects corporate tax treatment.
7. Open a business bank account Bring your EIN Confirmation Letter, Articles of Organization approval, photo ID, and Operating Agreement. Maryland's banking market includes M&T Bank (Baltimore-headquartered, major Mid-Atlantic presence), Sandy Spring Bank, Truist, and all major national banks. A separate business account maintains the LLC's liability shield and is required for opening most commercial bank accounts.
8. File the Annual Report and Personal Property Return each year by April 15 Maryland LLCs must file an Annual Report and Personal Property Return with SDAT by April 15 each year ($300 fee). File at businessexpress.maryland.gov or sdat.dat.maryland.gov. LLCs with no tangible personal property in Maryland may qualify for the Trader exemption on assessed value — report zero personal property on the return. The $300 filing fee is not waived by the exemption. Failure to file by April 15 results in forfeiture of good standing. Reinstatement requires additional fees and filings.

Formation context

Who should form in Maryland?

Recommended for

Businesses genuinely operating in Maryland — biotech, healthcare, defense, and government contracting near Baltimore, Bethesda, and Annapolis; Johns Hopkins, UMBC, and NIH-adjacent research commercialization and spin-out entities; Defense contractors and federal government services firms in the Baltimore–Washington corridor (Northrop Grumman, Leidos, SAIC supply chain); Entities seeking Mid-Atlantic institutional access where Maryland nexus is required — not recommended for pure cost-minimization formation strategies

Tax treatment (default)

Pass-through by default: single-member LLCs are disregarded entities (Schedule C); multi-member LLCs are partnerships (Form 1065). Maryland imposes no franchise tax on LLCs. Members pay Maryland's graduated individual income tax (2%–5.75% state + 2.25%–3.20% county/city) on MD-source pass-through income. Corporate income tax: 8.25% (highest in biz-license dataset) — applies only to entities electing C-corp tax treatment. The $300 Annual Report fee is not an income tax — it is an assessment-based administrative filing.

If you live outside Maryland but form here, you will likely need to register as a foreign LLC in your home state — compounding the $300/yr Maryland annual report with additional home-state fees. Maryland is the right choice for businesses with genuine Maryland-nexus operations, not for cost-minimization formation strategies. Virginia ($50/yr) or Wyoming ($60/yr) are better choices for cost-focused formation without Maryland operational requirements.

No publication requirement in Maryland — unlike New York or Nebraska, you do not need to publish notice in a newspaper after filing.

FAQ

Common Maryland LLC formation questions

Still deciding between an LLC, sole proprietorship, S-Corp, or C-Corp? Our entity-type comparison breaks down formation cost, tax treatment, liability shield, and compliance complexity for all four structures side by side.

Once your LLC clears ~$80K in annual net profit, an S-Corp election (IRS Form 2553) typically saves $5,000–$15,000/year in self-employment taxes by splitting owner income into a W-2 salary + tax-free distributions. The election is free — Form 2553 has no IRS filing fee. The key decision factors: your net income level, a defensible reasonable-compensation salary, and the 75-day Form 2553 filing window after LLC formation.

Already operating as a sole proprietor, or wondering whether a cheap county DBA filing ($10–$100) is enough instead of forming an LLC? A DBA lets you operate under a trade name — but provides zero liability protection. Our DBA vs LLC comparison breaks down exactly when a DBA is sufficient and when you need a state LLC filing.

Missing your annual report deadline triggers late fees and — if left long enough — administrative dissolution, which voids your LLC's liability shield until reinstated. Know your Maryland deadline, fee, and the consequences of missing it.

If your LLC opens an office, hires employees, or regularly does business in another state, you must foreign-qualify there — or face fines, back taxes, and loss of standing to sue. Our foreign qualification guide covers when you need it, how to file a Certificate of Authority, and what it costs.

Your Articles of Organization are filed — now make your LLC operational. Four actions every new LLC owner needs to take:

Commingling personal and business funds is the #1 way LLC owners lose their liability shield. A separate business account — in your LLC's legal name, with your EIN — is the foundational act of corporate formality. Mercury, Novo, Bluevine, Relay, and Found open same-day with no monthly fees. Compare online banks vs. Chase and Bank of America.

How you pay yourself depends on your LLC's tax classification — not what you call the transfer. A disregarded single-member LLC pays via owner draw with SE tax on all net profit. An S-Corp-elected LLC splits income between a W-2 salary (FICA applies) and tax-free distributions. Getting this wrong triggers IRS audit risk and SE-tax errors.

Single-member LLCs file Schedule C with their personal Form 1040 (due April 15). Multi-member LLCs file Form 1065 by March 15. S-Corp-elected LLCs file Form 1120-S by March 15. Know your form, your deadline, and the common deductions — home office, vehicle, retirement contributions, and startup costs — before your first April filing.
