St. Marys County Property Tax Due Date

Maryland property taxes are levied by both the state and local governments (counties and municipalities). Property is assessed at full cash value (100% of market value) by the State Department of Assessments and Taxation (SDAT). Counties then apply their own tax rates to that value. Maryland conducts reassessments on a three-year rolling cycle — approximately one-third of all properties are reassessed each year. When a property is reassessed and value increases significantly, Maryland phases in the increase over three years to reduce the impact on property owners. This phased-in value (rather than the full assessed value) is what your tax bill is based on.
