About this estimate: it adds the state fees described on this page and the cost of a registered agent or registered office service. It may leave out a state tax on the LLC itself. We have not confirmed how Maryland applies its recurring fees and taxes to an LLC formed in another state, so check them with the state before you budget.
If your LLC was formed in another state but you're conducting business in Maryland, you must register as a foreign LLC to operate legally in the state. Whether you need to register depends on what Maryland law counts as doing business there. Activities such as keeping an office, having employees or owning property in Maryland can count. The foreign LLC registration process involves filing an Application for Registration of a Foreign Limited Liability Company with a $100 filing fee. However, the total first-year costs range from $450 to $700 when including Maryland's $300 Annual Personal Property Return fee and registered agent expenses. An LLC that does business in Maryland without registering can be barred from bringing a lawsuit in Maryland courts until it registers, and the state can charge fees and penalties. Understanding Maryland's specific requirements and deadlines matters for maintaining good standing and avoiding costly compliance issues.

Before You File: Prerequisites
- Certificate of Good Standing (or Certificate of Status) from your home state, dated within 60 days
- A registered agent with a physical address in Maryland
- Your LLC's complete legal name and any trade names you plan to use in Maryland
- The principal office address of your LLC in its home state
- Information about your LLC's management structure, including names and addresses of all members or managers
- A clear understanding of whether your LLC name is available in Maryland or if you need to adopt a trade name
- Payment method for the $100 filing fee
How to Register a Foreign LLC in Maryland: Step-by-Step
- 1
Obtain a Certificate of Good Standing
Contact your home state's Secretary of State office to request a Certificate of Good Standing or Certificate of Status for your LLC. This document must typically be dated within 60 days of filing your Maryland foreign registration application. Your home state sets the fee and how long this takes, so order it early and check both with the office that issues it. The certificate verifies that your LLC is in good standing and authorized to do business in its state of formation, which Maryland requires as proof of your LLC's valid existence.

Appoint a Registered Agent in Maryland
Maryland law requires you to designate a Maryland Resident Agent with a physical Maryland street address. The agent must be a Maryland resident or a Maryland-authorized entity. Your registered agent will receive official state correspondence and legal documents on behalf of your LLC. You can serve as your own registered agent if you've a Maryland address, hire a professional registered agent service for a yearly fee, or appoint a trusted Maryland resident who agrees to fulfill these responsibilities consistently.
Before you compare paid services: in most states the LLC's owner, or another individual who qualifies, may serve as its registered agent themselves, generally subject to that state's rules on keeping a street address in the state and being available there during normal business hours. A paid service is one way to meet the requirement and not the only one. The Maryland registered agent requirements set out what Maryland itself asks.

Check Your LLC Name Availability
Search Maryland's business entity database to determine if your LLC name is available. Maryland requires a name that's distinguishable from existing Maryland entities. If your exact LLC name is unavailable, you must adopt a trade name acceptable to the State Department of Assessments and Taxation. You can check name availability through the Maryland business entity search tool on the SDAT website. If you need a trade name, ensure it complies with Maryland's naming requirements and doesn't infringe on existing trademarks or business names.

File the Application for Registration of a Foreign Limited Liability Company
Complete and submit the Application for Registration of a Foreign Limited Liability Company through the Maryland State Department of Assessments and Taxation. You can file online at https://dat.maryland.gov/SDAT/llfforms.html or by mail with a $100 filing fee. The application requires your LLC's legal name, principal office address, registered agent information, management structure details, and the purpose of your business activities in Maryland. Online filing is strongly recommended due to faster processing times and immediate confirmation of successful submission.

Understand Your Ongoing Tax Obligations
You must register with the Maryland Comptroller's Office for applicable state taxes including income tax withholding if you've employees, sales and use tax if you sell taxable goods or services, and unemployment insurance tax for employees. Contact the Comptroller's Office to determine which tax registrations apply to your specific business activities. These registrations are typically required within 60 days of beginning business operations in Maryland and have their own filing deadlines and payment requirements throughout the year.

File Your Annual Report / Ongoing Compliance
Maryland requires all foreign LLCs to file an Annual Personal Property Return by April 15 each year with a $300 fee. This annual filing maintains your LLC's good standing and authorization to do business in Maryland. The return must include updated information about your LLC's activities, property holdings, and business operations within the state. If a required filing is missed, Maryland can end the LLC's authority to do business in the state. We have not confirmed Maryland's specific timeline or what it costs to restore that authority.
Cost Breakdown
The total first-year cost for foreign LLC registration in Maryland ranges from $450 to $700, including the $100 State Department of Assessments and Taxation filing fee, the $300 Annual Personal Property Return fee due by April 15, and a registered agent fee that varies by provider. Professional registered agent services charge a yearly fee, while appointing yourself or a trusted Maryland resident requires maintaining a consistent Maryland address for official correspondence.

Processing Timeline
We have not confirmed a current processing time or expedited service fee for a foreign LLC registration in Maryland, so this page does not quote one. Processing times change with the office's workload and with how you file. Check the current time, and whether a faster paid service is offered, with the state filing office before you plan around a date.
Maryland-Specific Warnings
Maryland's $300 Annual Personal Property Return fee is one of the highest annual compliance costs in the Mid-Atlantic region
Maryland's $300 Annual Personal Property Return fee significantly exceeds the annual fees in neighboring Virginia ($50 annual registration fee), Pennsylvania ($7 annual report) and West Virginia ($25 annual report), though it is below Delaware's $400 annual LLC tax. This substantial ongoing cost can impact your LLC's annual budget, especially for smaller businesses. Factor this expense into your financial planning and ensure you budget $300 every year by April 15 to maintain good standing in Maryland.
Confirm Maryland's processing time before you commit to a date
We have not confirmed a current processing time or expedited service fee for a foreign LLC registration in Maryland. If a contract, a lease or a closing depends on your registration, check the current time with the state filing office first, and ask whether a faster paid service is offered and what it costs.
Missing a required filing can end your authority to do business in Maryland
If a required filing is missed, Maryland can end the LLC's authority to do business in the state. We have not confirmed Maryland's specific timeline or what it costs to restore that authority. This means you can't legally enter contracts, maintain business operations, or access Maryland courts. Reinstating from forfeiture requires filing all overdue returns, paying accumulated fees and penalties, which can become substantially more expensive than timely compliance.
