The moment your corporation crosses into Maryland's marketplace, you become a foreign entity if you were formed elsewhere. Before signing a lease, hiring employees, or earning revenue here, you must file with the State Department of Assessments and Taxation (SDAT).
Maryland uses the term foreign qualification when all your activity happens inside state borders and foreign registration when your Maryland operations are just one piece of a multistate footprint. Both processes use identical paperwork under Title 7 of the Corporations and Associations Code, specifically § 7-202.
You’ll need a foreign qualification if your entity is doing business in Maryland. That phrase is the trigger: once your activity crosses the doing-business line, SDAT expects you to register (for interstate business) or qualify (for intrastate business). Each state defines “doing business” differently, so generic checklists won't cut it, as you need Maryland's specific rules.
Section 7-202 divides foreign activity into two buckets:
The paperwork and fees are identical. The labels matter mainly because the statute uses them to describe which form you file. Either way, the key is the pattern and frequency of your activity.
You should plan to file if you consistently do any of the following:
While not exhaustive, SDAT treats these touchpoints as clear evidence that your company is active enough to require a filing.
Maryland carves out several safe harbor activities that, on their own, don't trigger registration. You can:
These exceptions come straight from the statutory text, so you can rely on them as long as they remain incidental. Combine any with day-to-day revenue generation, and the safe harbor disappears.
Skipping registration strips you of critical legal rights and adds real cost. An unregistered foreign corporation cannot file or maintain a lawsuit in the state until it cures the defect. You can defend yourself, but you can't sue for unpaid invoices or breach of contract until SDAT accepts your filing.
When you do file, SDAT adds a flat $200 fine for each year (or portion thereof) you previously operated without authority, as authorized by state law. Every officer or agent who knowingly transacts business without qualification commits a misdemeanor and faces fines up to $1,000.
You register a foreign corporation with SDAT through the agency's Business Services Division. You can file either online through Maryland Business Express or by mailing hard-copy forms to Baltimore.
Online submissions are processed directly in the SDAT queue and allow you to pay by credit card, making electronic filing faster and more traceable. If you prefer paper, include a self-addressed stamped envelope so SDAT can return the stamped-filed copy.
Start with the Foreign Corporation Qualification Form. SDAT asks for basic but precise information:
Attach a Certificate of Good Standing (sometimes called a Certificate of Existence), issued by your home state within the last 60 days.
The President or Vice President signs on behalf of the corporation, and the resident agent signs a separate consent clause that makes them officially responsible for service of process inside the state. A faxed or scanned signature will draw an automatic rejection.
If your company has already been conducting business in Maryland, check the box that says so on the form and plan to remit SDAT's statutory $200 penalty at the time of filing. The penalty is mandated by § 7-302 and can't be waived because you "didn't know" you needed to register.
Online filers upload PDFs through Business Express, pay the fee, and receive a tracking number to monitor status.
Maryland expects you to use the exact corporate name that appears on the Certificate of Good Standing.
Before filing, run a quick search in Business Express to be certain no Maryland entity already uses that name. If the name is taken or if it lacks a corporate designator like "Inc.", Maryland stipulates that you have two options:
Trade names are filed with Maryland's Secretary of State, cost $25, and do not give you exclusive rights beyond Maryland borders.
Maryland bars names that imply a purpose you are not authorized to pursue ("Bank" if you are not chartered as one) and prohibits words suggesting affiliation with a federal or state agency. If you plan to use a restricted word like “Insurance," "Trust," or "Engineer," be ready for SDAT to request proof of the relevant professional license or regulatory approval.
Remember: a trade name does not replace the legal corporate name. You still list the legal name on all state filings and contracts; the trade name is simply how you hold yourself out to Maryland customers.
Processing times fluctuate with SDAT's workload; always confirm current estimates on Business Express.
Once SDAT stamps the filing "accepted," your corporation is officially authorized to do business in Maryland. You will see the entity status switch to "good standing" in the Business Express portal, and SDAT will mail the endorsed copy to the address you provided.
You can't register in Maryland without a registered agent with a real Maryland address. Their job is straightforward but critical: accept legal papers, government notices, and tax correspondence on your behalf, stamp them with the date received, and get them to you quickly.
SDAT will reject your filing outright without a Maryland agent listed, and you lose the legal protection that comes from being properly registered. You have three routes to meet the requirement:
Whichever option you choose, the agent's name and street address go on the Foreign Corporation Qualification form, and the agent must sign the filing.
Qualifying in Maryland is only the opening move. To keep the legal shield you came for, you have to stay in the state's good graces year after year. Here’s what you need to consider:
When you're ready to leave Maryland for good, you must formally withdraw; simply letting filings lapse only trades routine compliance for mounting penalties. File the Certificate of Withdrawal (SDAT sometimes labels it 'Application for Termination') and pay a $100 filing fee (confirm the latest fee on the official SDAT site), plus any applicable expedited fee.
How long is a Certificate of Good Standing valid for Maryland registration?
SDAT wants a Certificate of Good Standing or Certificate of Existence that's no more than 60 days old when you file.
How do I amend my foreign registration information?
Any time your principal office moves, you switch resident agents, or you rebrand, you file an amendment with SDAT. The form mirrors the original qualification application and must carry original signatures from a corporate officer and the new resident agent. Until SDAT processes the change, the old information remains on the public record.
What happens if my company's status changes in our home state?
Your Maryland authority is tied to your home-state charter. If you fall out of good standing back home, Maryland can revoke your foreign qualification. Keep your domestic filings current and promptly file withdrawal or merger documents in Maryland to avoid surprise forfeitures.
What are common filing mistakes to avoid with Maryland foreign registration?
The big three are submitting a stale Certificate of Good Standing, forgetting the resident agent's original ink signature, and omitting the $200 "late activity" penalty when you admit you've already been doing business. Each mistake triggers a rejection and resets the processing clock.
