About Property Taxes in Maryland
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.
Payment & Assessment
Maryland property tax bills are typically mailed in July, covering the fiscal year from July 1 to June 30. Payment schedules vary by county: Most counties: Due September 30 (full year) or semi-annual installments (September 30 and December 31, or other dates). Some counties offer a 30-day grace period. Late interest of 1% per month typically applies. Most counties offer online payment through the county government website. Contact your county finance department for payment options.
