Maryland Foreign LLC Registration 2026: $100 Filing + $300 Annual Report

What You Need to Register

Foreign registration is filed on SDAT's Limited Liability Company Registration form (the version for non-Maryland LLCs). It is not called a "Certificate of Authority" in Maryland. Here is what the form and filing require:

• Your LLC's full legal name in its home jurisdiction (if that name is already taken in Maryland, you must register under an alternate name that includes "Limited Liability Company" or "LLC")
• A Maryland resident agent with a physical Maryland street address (no PO boxes)
• Written proof of existence from your home state — equivalent to a Certificate of Good Standing — issued within the last 60 days
• Your LLC's state and date of formation, principal office address, and the nature of its business in Maryland
• The $100 filing fee (plus a $200 penalty if the LLC already did business in Maryland before registering)

Step-by-Step: How to Register

1. Check name availability in the Maryland Business Express database and decide if you need an alternate name.
2. Obtain proof of good standing from your home state (e.g., Delaware Division of Corporations, Virginia SCC), and make sure it is dated within the last 60 days.
3. Appoint a Maryland resident agent — either a Maryland resident individual or a commercial registered agent service.
4. Complete the Limited Liability Company Registration form with all required information (home-jurisdiction name, Maryland name if different, state and date of formation, principal office, nature of business, and resident agent details).
5. File with SDAT through the Maryland Business Express online portal, attach the good-standing certificate, and pay the $100 filing fee.
6. Save your confirmation and set reminders for the April 15 Annual Report deadline.

Standard review takes roughly 4–6 weeks for paper filings and 6–8 weeks for non-expedited online filings. If you need it faster, add the $50 expedited fee for review within about 7–10 business days; same-day online processing is also available for a higher rush fee. Maryland Business Express adds a 3% service fee to online card payments.

After Approval: Ongoing Compliance

Once your foreign LLC is registered in Maryland, you have the same ongoing obligations as a domestic Maryland LLC:

• File the $300 Annual Report (Form 1) by April 15 each year — foreign LLCs use the same Form 1 and fee as domestic Maryland LLCs (see our Maryland LLC annual report guide)
• Maintain your Maryland resident agent and physical address (details in our Maryland registered agent guide)
• Register for Maryland tax obligations as required (state income tax, sales tax, employer withholding) — see our Maryland LLC taxes and fees breakdown
• Keep your home state LLC in good standing as well — if your home state dissolves or revokes your LLC, Maryland may follow suit

Filing the Annual Report after April 15 does not trigger a flat fee. The penalty is 1/10 of one percent of the entity's assessed Maryland property value (or a base penalty of $30-$50 depending on how late you are, whichever is greater), plus 2% interest on that penalty for each 30-day period the report is overdue. A late or missing Annual Report also costs your LLC its good standing until you file. You can request a 60-day extension (to June 15) through SDAT before the deadline.

D.C. Metro Area: Multi-State Considerations

The D.C. metropolitan area spans Maryland, Virginia, and the District of Columbia. Many business owners in this region form their LLC in one jurisdiction but operate across state lines. Common scenarios:

• Delaware LLC operating in Maryland: popular for liability protection + Delaware's flexible LLC statute, but requires Maryland foreign LLC registration.
• Virginia LLC with Maryland clients: if you have a physical presence or significant activity in Maryland, registration is typically required.
• Maryland LLC expanding to Virginia: you'd register as a foreign LLC with the Virginia SCC.

If you operate across multiple jurisdictions, a registered agent service that covers multiple states can simplify compliance tracking and ensure you don't miss deadlines in any state.

Common Mistakes

• Operating in Maryland without registering first — this adds a $200 penalty and can limit your ability to sue in Maryland courts
• Submitting a good-standing certificate older than 60 days (Maryland will reject it)
• Using a Virginia or D.C. address for your Maryland resident agent (must be a physical Maryland address)
• Forgetting the April 15 Annual Report deadline after initial registration
• Letting your home state LLC fall out of good standing (can trigger issues in Maryland too)
• Not checking name availability before filing — if your name conflicts, your application may be rejected
