How to form an LLC in Maryland

Forming an LLC in Maryland costs $100 (plus a $3 expedite fee that's automatically included online) to file Articles of Organization with the Maryland State Department of Assessments and Taxation (SDAT), with online approval through Maryland Business Express in roughly 7 business days. The catch is the annual report — Maryland's "Personal Property Return" — at $300 per year, tied with Massachusetts for the highest in the U.S. and mandatory regardless of revenue. Maryland's top individual income tax rate is 5.75%, and most counties layer their own local income tax on top (up to 3.20%). The state's economy is uniquely federal-government adjacent: cybersecurity (NSA, Fort Meade), bioscience (NIH, Bethesda), and federal contracting dominate. For founders in those sectors, Maryland's costs are usually justified by ecosystem access; for everyone else, the $300/year annual report makes Virginia or Delaware more attractive.

   Calendar the annual Personal Property Return

   Maryland's annual report is called the "Personal Property Return" and is due April 15 every year through SDAT. The fee is $300 — among the highest in the U.S. and mandatory regardless of activity. Late filings incur penalties.

Should you use a formation service in Maryland?

You can absolutely file directly with the Maryland State Department of Assessments and Taxation (SDAT) for the $100 state fee.
