Three numbers, three agencies

Asking for the wrong number is a common reason a search comes back empty.

Number	Issued by	What it identifies
Federal EIN	Internal Revenue Service	Identifies the business for federal tax. It is the same number in every state.
Department ID number (SDAT identification number)	Maryland State Department of Assessments and Taxation (SDAT), Business Services Division, Business Charter Unit	Identifies the entity's record in the state registry. A letter prefix that shows the entity type, usually D, F, W, L or Z, followed by digits; the 2026 Form 1 lists D or F for corporations and W or Z for LLCs
Maryland Comptroller tax account number (Combined Registration)	Comptroller of Maryland	SDAT issues its own Department ID, usually starting with D, F, W, L or Z, which is not the federal EIN. The EIN comes from the IRS, and state tax accounts come from the Comptroller's Combined Registration, which asks for both numbers.

What a Maryland status means

Status	What it means
Good Standing	The active entity complies with the Maryland filing and payment rules SDAT tracks.
Not in Good Standing	The entity is out of compliance with one or more Maryland laws, often a missing Form 1 or an unpaid late penalty; voluntarily terminated entities also show this.
Forfeited	The entity's right to do business in Maryland and to use its name has been relinquished; a forfeited domestic corporation has no legal existence.

Fees and annual filings

LLC formation	$100 (Articles of Organization)
Corporation formation	$100 (Articles of Incorporation) plus a $20 organization and capitalization fee when aggregate par value of stock is not over $100,000
Annual filing	Form 1, Business Entity Annual Report and Business Personal Property Return
Annual fee, LLC	$300 (Form 1)
