How to Register a Business in Maryland: SDAT Foreign Qualification Guide (2026)
If your company was formed in another state and now has employees, an office or regular business in Maryland, you register with the State Department of Assessments and Taxation (SDAT), not the Secretary of State. Corporations file a Foreign Corporation Qualification; LLCs file a Foreign LLC Registration. Here is what it costs, what you need, and what comes after.

Do you need to register in Maryland?
You generally need to register if your company is "doing business" in Maryland, for example if you:
Have an office, store or warehouse in Maryland
Employ people who live and work in Maryland
Regularly sell to, or provide services for, Maryland customers
Activities that usually don't count on their own include holding a bank account in Maryland, holding internal meetings there, and isolated one-off transactions. If you're unsure, check with your attorney or book a call with us.
Hiring a remote employee in Maryland always means opening Maryland payroll tax accounts, even when Secretary of State registration isn't required. See the payroll section below.
How to register, step by step
Get a certificate of good standing from your home state. Maryland won't accept one more than 60 days old.
Choose a Maryland resident agent. See the rules below.
File through Maryland Business Express. The fee is $110. If you've already been doing business in Maryland, add a $200 penalty.
Save your approval and SDAT ID number. You'll need them for payroll and tax registrations.
Registered agent rules in Maryland
Maryland calls the registered agent a resident agent. Every registered business must name one with a Maryland street address (no P.O. boxes), and the agent signs a consent. If you don't keep an agent, SDAT becomes your agent by default, which means legal papers may never reach you.
Using an employee as your agent is allowed, but it means legal papers go to one person's home, and they're lost if that person leaves. A commercial registered agent avoids that. Every AbstractOps plan includes registered agent service.
Annual report: every year by April 15
Every business registered in Maryland files Form 1, the annual report and business personal property return, by April 15 each year. The fee is $300 for corporations and LLCs. You can request a 60-day extension to June 15.
Late reports bring penalties, and companies that stop filing lose their right to do business in Maryland.
Maryland payroll accounts
If you have employees in Maryland, you'll also need:
A withholding account with the Comptroller of Maryland, which also covers county income tax.
An unemployment insurance account with the Maryland Department of Labor.
Our Maryland payroll tax registration guide walks through the details.
