State Assessments

The State Department of Assessments and Taxation (SDAT) determines the taxable assessment of your real property. The taxable assessment equals the full cash value, as 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.

Property owners requiring more precise details about an assessment, or the appeal process, should call SDAT's local office at 410-480-7940 or email sdat.how@maryland.gov, SDAT's main line at 410-767-1184 or email sdat.411@maryland.gov, or visit SDAT's website at https://dat.maryland.gov.
