Nonresident sale of property
If you sell or exchange real property that you own in Maryland, tax must be withheld at the time of sale unless a specific exemption applies. The tax will be withheld based on the total payment from the sale of that property and associated tangible personal property. The person responsible for recording the deed must pay the withholding tax to the Clerk of the Court or the State Department of Assessments and Taxation (SDAT) at the time of recordation. The payment must be made before the deed or other instrument of transfer is recorded with the court, or filed with the SDAT. For more information, see Sales of Real Property by Nonresidents (below).
