Maryland Department of Assessments and Taxation - SDAT (entity formation) / Maryland Comptroller (business tax registration) / Local jurisdiction for local licenses
Step by Step
How to do it
Determine your business structure: sole proprietor, LLC, corporation, partnership
Register your business entity with the Maryland Department of Assessments and Taxation (SDAT) (for LLCs and corporations) - file online through Maryland Business Express at businessexpress.maryland.gov; SDAT is the agency that handles both business entity registration AND property assessment in Maryland
Obtain an EIN (Employer Identification Number) from the IRS at irs.gov if forming an entity, hiring employees, or operating as a partnership
Register with the Maryland Comptroller for state business taxes:
- Sales and Use Tax License (if selling taxable goods/services) - free to register at marylandtaxes.gov
- Withholding Tax registration (if you have employees)
Register online at marylandtaxes.gov or through Maryland Business Express (integrated portal)
OBTAIN A LOCAL BUSINESS LICENSE from the County Clerk of the Circuit Court - Maryland requires most businesses to obtain a county business license through the Clerk of the Circuit Court (not a separate county office) in the county where the business is located; fees vary by business type and county; apply at mdcourts.gov/clerks for your county
Check for industry-specific state licenses: contractors (Maryland Home Improvement Commission - MHIC; DLLR); health professionals, real estate, cosmetologists, engineers, and others require licenses through the Maryland Department of Labor (DLLR) at labor.maryland.gov
Renew entity annual report/personal property return with SDAT; renew county business license annually; renew professional licenses per applicable board

County-specific variations apply
Maryland's county business licenses are issued by the Circuit Court Clerk's office in each county - a unique arrangement not found in most states. Fees and required license types vary significantly by county and business type. Some business types (food service, liquor, etc.) require additional county health and liquor board approvals. Baltimore City has its own separate licensing requirements.
