Real Property Tax - State Assessment

The State Department of Assessments and Taxation (SDAT) determines the taxable assessment of your real property. The taxable assessment equals the full cash value, determined by the Assessor’s Office. It is important to verify any assessment notices received from SDAT for accuracy. Assessments may be appealed.

Online assessment information is available at SDAT.

Anyone desiring more precise details about an assessment, or the appeal process, should call SDAT at 410-480-7940 or visit its website at www.dat.state.md.us.
