The State of Maryland has different tax laws and definitions.  Maryland's general rule to determine residency. 

  • If you live in Maryland during the tax year and have income in Maryland, you file a Resident Tax Return.
  • If you live outside Maryland during the entire tax year and have Maryland income, you file a Nonresident Tax Return.
  • If you live in Maryland and another U. S. state during the same tax year, you file as a part-year resident for the time you lived in Maryland using Resident Individual Form. You also may need to complete a Nonresident Individual Form if you continue to receive Maryland income after moving out of the state.

Maryland does not recognize tax treaties. Nonresident aliens with treaty exemptions from federal taxes may be subject to state taxes.
