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.

About Garrett County
Garrett County is the westernmost county of the U.S. state of Maryland, completely within the Appalachian Mountains. As of the 2020 United States census, the population was 28,806, making it the third-least populous county in Maryland. Its county seat is Oakland. The county was named for John Work Garrett (1820–1884), president of the Baltimore and Ohio Railroad. Created from Allegany County in 1872, it was the last county to be formed in the state. The county is part of the Western Maryland region of the state. Garrett County is bordered by four West Virginia counties and to the north the Maryland–Pennsylvania boundary known as the Mason–Dixon line. The eastern border with Allegany County was defined by the Bauer Report, submitted to Governor Lloyd Lowndes, Jr. on November 9, 1898. The Potomac River and State of West Virginia lie to the south and west.
