‹ Maryland Filing Guide · All Penalties
Operating in Maryland without a certificate of authority can trigger a civil penalty under state statute and bar your LLC from Maryland courts. See the consequences and next steps below.
Maryland pairs an entity charge with personal criminal exposure. SDAT imposes a $200 penalty on a foreign LLC that has done business in Maryland without registering, and each member of that LLC and each agent who transacts business for it in Maryland is guilty of a misdemeanor subject to a fine of not more than $1,000 per person on conviction. Until the $200 penalty is paid and the company has either complied or stopped doing business in the State, neither the LLC nor anyone claiming under it may maintain suit in any Maryland court. Contracts remain valid.
| What's at stake | If you don't register | Severity |
|---|---|---|
| Civil penalty | $200 penalty imposed by SDAT on the company, plus a misdemeanor fine of not more than $1,000 on conviction against each member and each agent who transacted business in Maryland. The $200 is an administrative penalty imposed by SDAT and is collectible, reducible or abatable under Tax-Property Article 14-704; it must be paid before the company or anyone claiming under it can maintain suit. The $1,000 is criminal, charged per member or agent and set by the court on conviction, not a company charge.Checked Sep 26, 2026 · mgaleg.maryland.gov | High |
| Back fees on cure | Standard registration fees apply on cure. The statute does not specify a separate retroactive assessment, but the state may still collect missed report fees. | Medium |
| Right to sue in state court | Closed. You cannot bring or maintain any lawsuit in state court until you register. If you need to sue a customer, a partner, or a vendor, you have to register first. You can still defend yourself if someone sues you. | High |
| Contract validity | Contracts generally remain valid, but registration may be required before you can sue to enforce them. | Low |
| Personal liability | Personal criminal fines can apply on conviction. The penalty row above explains the fine and who can be charged. | High |
| State tax exposure | Possible. Maryland follows how your LLC is taxed federally. LLCs taxed as C corporations file corporate returns; others generally report income through their owners. Separate returns, taxes for out-of-state owners and sales tax may still apply. Owning income-producing real estate or physical property generally requires Maryland LLC registration, with exceptions for certain foreclosed property. Verify with the Comptroller of Maryland. | Medium |
| How it gets enforced | The penalty follows the process in the cited statute. Check the conditions above before treating a listed fine as an amount you owe. | N/A |
Here's how to fix it before any of this catches up to you.
You can file the foreign qualification yourself directly with the Maryland State Department of Assessments and Taxation for the standard filing fee. A wrong form version, a missing certificate of good standing from your home state, or a name conflict with an existing entity can delay approval. Check the form and required documents before submitting. The consequences of remaining unregistered are described above; they do not all accrue weekly.
File it yourself$100 + $125 = $225, the state fee plus a registered agent for the year
Have Northwest file it$100 + $225 = $325, the state fee plus the service, one year of registered agent included
These totals cover registration and the listed service only. Back fees, penalties, taxes and required attachments are extra. The DIY example includes a paid agent. State fees paid by card through Northwest carry a 2.7% card charge. Both routes leave you with the same registered agent obligation from year two.
Want help with the paperwork? Northwest can prepare and submit your foreign registration and serve as your registered agent. Hiring a service does not erase overdue fees, taxes or penalties.
