‹ 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. Here's the full cost.
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. | High |
| Back fees on cure | You owe every fee and tax that would have been due if you had registered on time. That includes registration fees and annual report fees for each year unregistered. | High |
| 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 | Your contracts stay enforceable. Failing to register does not void any deal you signed, and the other party still owes you what they agreed to. | Low |
| Personal liability | Personal civil penalty exposure under state statute. Each member, manager, or employee who knowingly transacts business unregistered can be held personally liable, separate from the LLC itself. | High |
| State tax exposure | Possible. Maryland imposes corporate income tax (under Md. Code Tax-Gen. Title 10) and sales tax on LLCs doing business in the state. Maryland's definition of 'doing business' under s. 4A-1009 includes owning income-producing real or tangible personal property in Maryland. Verify with the Comptroller of Maryland. | Medium |
| How it gets enforced | Imposed by the court when an unregistered LLC tries to sue or is otherwise discovered. | 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 Secretary of State for the standard filing fee. The application looks straightforward, but rejections are common. A wrong form version, a missing certificate of good standing from your home state, or a name conflict with an existing entity will bounce the filing and reset the clock by two to three weeks. Every week you stay unregistered is another week of penalty accrual.
Northwest reviews your application before it goes in, catches the rejection-causing mistakes (form version, name conflict, missing certificate of good standing), and submits same-day in most states. They'll also serve as your registered agent so the filing meets the statutory requirement on day one. If something is wrong, they fix it before the Secretary of State sees it, not after a rejection notice arrives three weeks later.
