Maryland trips up founders because it runs formation through the Maryland State Department of Assessments and Taxation (SDAT), not a Secretary of State. Most national templates assume a Secretary of State flow, and that assumption is wrong here.
Three agencies split the work. SDAT forms the entity. The Comptroller of Maryland handles tax accounts. The Internal Revenue Service (IRS) issues the federal Employer Identification Number (EIN). This guide walks the full sequence, with fees and timelines verified against the live Maryland Business Express pages.
What Is the Maryland Business Registration Process?
You form your entity with SDAT through Maryland Business Express, get an EIN from the IRS, open Comptroller tax accounts, obtain any required licenses, and file an annual report each year. The process mirrors the state’s own official sequence, and most of it happens online in one portal.
| Step | Agency | Form / Portal | Fee | Source |
|---|---|---|---|---|
| Form the entity | SDAT | Articles of Organization or Incorporation via Maryland Business Express | $100 LLC / $120 stock corporation | Maryland Business Express Fees |
| Get an EIN | IRS | Online EIN application | Free | IRS |
| Open tax accounts | Comptroller of Maryland | Maryland Tax Connect | Free | Comptroller of Maryland |
| Obtain licenses | State / county | Maryland OneStop | Varies by industry | Maryland OneStop |
| File annual report | SDAT | Annual Report via Maryland Business Express | $300 (LLC, corp, LP, LLP) | Maryland Business Express Fees |
Who Handles Business Registration in Maryland: SDAT or the Secretary of State?
SDAT handles it. SDAT registers entities, keeps charter documents, processes annual reports, and issues Certificates of Status, per the SDAT business division. Maryland’s Secretary of State handles charities, notaries, and trademarks, not business formation. For example, a Maryland trademark is a $50 filing with the Secretary of State’s Trademark Division, not SDAT.
Maryland Business Express is SDAT’s online portal, operated with partner Tyler Maryland. It requires a free user account, and one account can manage multiple businesses, per the Maryland Business Express portal. The account also lets you pause a registration and resume it later, so you do not have to finish in one session.
SDAT answers charter questions at 410-767-1330, or toll-free at 888-246-5941, per the SDAT contacts page. Paper charter filings go to SDAT Charter Legal, 700 E. Pratt St., Suite 2700, Baltimore, MD 21202-6377, the office’s address since its 2024 move to the Candler Building, per SDAT contact information.
What Are the Types of Business Entities in Maryland?
Maryland recognizes the LLC, corporation, sole proprietorship, partnership, and nonprofit, and each files a different document (or none) with SDAT. Your choice sets liability, taxation, and ongoing fees. The table below shows the exact formation document for each, sourced to SDAT.
| Entity type | SDAT formation document | Source |
|---|---|---|
| LLC (Limited Liability Company) | Articles of Organization | SDAT / Maryland Business Express |
| Corporation (C-corp / S-corp) | Articles of Incorporation (S-corp is a federal Form 2553 election, not a Maryland entity type) | SDAT / Maryland Business Express |
| Sole proprietorship | None (trade name registration only if using a DBA) | SDAT / Maryland Business Express |
| General Partnership (GP) | None (trade name may be needed) | SDAT / Maryland Business Express |
| Limited Partnership (LP) | Certificate of Limited Partnership | SDAT / Maryland Business Express |
| Limited Liability Partnership (LLP) | LLP registration filed with SDAT | SDAT / Maryland Business Express |
| Nonprofit | Articles of Incorporation with SDAT, then a federal 501(c)(3) application to the IRS plus Maryland tax-exemption registration | SDAT / Maryland Business Express |
Watch the terminology. Maryland files Articles of Incorporation, not a “certificate of incorporation,” which is a Delaware term. Good standing in Maryland is proven by a Certificate of Status from SDAT. “Doing Business As” (DBA) and “trade name” mean the same thing here.
How Do You Choose and Search a Business Name in Maryland?
Search the Maryland Business Express Entity Search to confirm your name is distinguishable, then include the required suffix, such as LLC or Inc. You can reserve a name for 30 days for $25, per the SDAT name reservation form. The reservation renews in 30-day increments for $25 each.
The same tool verifies an existing business. You can search by Business Name, Department ID, or EIN, per the Entity Search page. Results show status (active, forfeited, cancelled, merged, or dissolved), formation date, entity type, and resident agent. An entity must show “Active” status to be eligible for certain filings, so a forfeited entity must be reinstated first. To pre-screen a name before you file, Commenda’s company name checker confirms availability in seconds.
Do I Need a Registered Agent in Maryland?
Yes. Every Maryland LLC, corporation, LP, and LLP must name a resident agent, which is Maryland’s term for a registered agent. The agent needs a physical Maryland street address, not a P.O. box, to receive legal documents. You must update SDAT promptly whenever the agent changes, or the entity risks falling out of good standing.
The agent can be an adult Maryland resident or an entity authorized to do business in Maryland. The owner can serve as agent if they meet the residency requirement. Sole proprietors and general partnerships generally do not need a resident agent because they file no formation documents with SDAT.
How Do You File Formation Documents With SDAT?
File online through Maryland Business Express, which needs a user account, or mail paper forms with a check to SDAT Charter Legal. Online filing is faster and guides you field by field. SDAT issues a business ID number once the entity is active, and that number identifies you on every future filing.
For an LLC, the worked example is the Articles of Organization: entity name, resident agent, principal office address, and an authorized signature. Corporations file Articles of Incorporation instead. Paper filers pay by check or money order to SDAT Charter Legal, 700 E. Pratt St., Suite 2700, Baltimore, MD 21202-6377.
How Much Does It Cost to Register a Business in Maryland?
An LLC pays a $100 base filing fee for Articles of Organization, and a stock corporation pays $120 for Articles of Incorporation, per the Maryland Business Express Fees schedule. Online card or PayPal payments add a 3% technology fee. The recurring $300 annual report fee is the figure most founders overlook.
| Filing | Fee | Source |
|---|---|---|
| LLC Articles of Organization | $100 | Maryland Business Express Fees |
| Stock corporation Articles of Incorporation | $120 | Maryland Business Express Fees |
| Nonstock / nonprofit corporation Articles | $170 | Maryland Business Express Fees |
| Trade name (DBA) registration | $25 | Maryland Business Express Fees |
| 30-day name reservation | $25 | SDAT name reservation form |
| Online payment technology fee | 3% of base fee | Maryland Business Express Fees |
| Expedited processing add-on | $50 | Maryland Business Express Fees |
| Rush / same-day processing | $325 | Maryland Business Express Fees |
| Annual report (LLC, corp, LP, LLP) | $300 | Maryland Business Express Fees |
| Annual report (sole proprietor, GP) | $0 | Maryland Business Express Fees |
How Long Does It Take to Register a Business in Maryland?
Standard filings are slow, and expedited or rush options buy speed. A regular filing is not reviewed until the second calendar month after submission, per the Maryland Business Express Processing Times page. Pay for expedited or rush service if you need the entity approved quickly.
| Filing method | Processing time | Source |
|---|---|---|
| Standard (regular) | Reviewed in the second calendar month after submission | Maryland Business Express Processing Times |
| Expedited ($50) | Initial review in 7–14 business days, not before the 7th business day | Maryland Business Express Processing Times |
| Rush ($325) | Reviewed within 3 hours if filed online before 2:30 p.m. on a business day | Maryland Business Express Fees |
How Do You Get an EIN for a Maryland Business?
Apply free on the IRS website after SDAT approves your entity. The EIN is required for hiring, federal taxes, and opening a business bank account. Online applications issue the number immediately during business hours, so this step takes minutes once you have your SDAT approval.
A single-member LLC with no employees can technically use the owner’s Social Security number, but an EIN is strongly recommended to keep business and personal finances separate. Multi-member LLCs, corporations, and any entity electing corporate taxation must have one.
How Do You Register for Maryland Tax Accounts?
Register with the Comptroller of Maryland through Maryland Tax Connect for sales and use tax, employer withholding, and unemployment insurance. Maryland’s state sales tax rate is 6%, with no local add-on rates, which is unusual among states. You register once through the combined online application and receive the accounts your business type needs.
Two more state steps follow in the official sequence. Businesses with employees must carry workers’ compensation coverage. Buying general business insurance is the final recommended step before you open your doors. To check where sales tax collection obligations arise as you grow, Commenda’s sales tax calculator looks up current rates by location.
How Do Sole Proprietors Register a Business in Maryland?
Sole proprietors operating under their own legal name file no formation documents with SDAT. If you operate under any other name, you must register a Trade Name with SDAT for a $25 base fee, per the Maryland Business Express Fees schedule. You may still need a sales and use tax license from the Comptroller plus county or local licenses.
The Comptroller of Maryland publishes tax guidance specific to sole proprietors, including how income passes through to your personal return. A trade name registration protects your public-facing name and satisfies the DBA requirement, but it does not create liability protection. Founders who want that protection usually form an LLC instead.
What Business Licenses Do You Need in Maryland?
Maryland has no single general business license, so requirements depend on your industry and county. Registration with SDAT and licensing are separate steps. Many retailers need a Trader’s License issued through the Clerk of the Circuit Court in their county, and regulated fields need their own permits. Use the Maryland OneStop portal as the central application hub.
Commonly licensed industries include food service, construction, childcare, health services, and transportation. County rules vary widely, so a license required in one county may not apply in another. Always confirm with your local clerk’s office before you operate. For a deeper walkthrough of state and county licensing, pair this with Commenda’s incorporation support described below.
How Do Out-of-State Businesses Register in Maryland?
An entity formed elsewhere registers as a foreign business through Maryland Business Express before doing business in Maryland. This is called foreign qualification. You appoint a Maryland resident agent and pay the applicable registration fee. Foreign qualification lets an out-of-state company operate legally in Maryland without forming a brand-new entity.
This matters for founders who incorporate in Delaware for fundraising but operate in Maryland. That company still foreign-qualifies in Maryland, which means two sets of filings and two annual reports. Weigh that ongoing cost against the reason for forming out of state in the first place.
What Are Maryland’s Annual Report and Personal Property Return Requirements?
Every Maryland entity files an Annual Report with SDAT by April 15. LLCs, corporations, LPs, and LLPs pay the $300 filing fee, while sole proprietors and general partnerships pay $0, per the Maryland Business Express Fees schedule. Businesses that own, lease, or use personal property also file a Personal Property Tax Return.
Miss these filings and SDAT marks the entity “not in good standing,” which leads to eventual forfeiture. Reviving a forfeited entity is slow and costly. File the report through Maryland Business Express each spring. A compliance calendar keeps the April 15 deadline and license renewals from slipping.
Do Maryland Businesses Need to File a BOI Report?
Probably not, but verify. Under the most recent FinCEN guidance, domestic reporting companies are exempted from Beneficial Ownership Information (BOI) reporting under the Corporate Transparency Act (CTA). The requirement now primarily affects certain foreign entities registered to do business in the United States.
This rule has changed more than once, and Maryland’s own portal added then struck the BOI step. Check current FinCEN guidance before you assume you are exempt, especially if your structure involves foreign entities.
