New Owners, please note the account ownership information is updated annually with our tax file, starting July 1st, from the State Department of Assessments and Taxation (SDAT). Please use the previous owner's last name or your parcel number to locate your account data. Using your address, you may be able to locate your account via the SDAT website.
Once you have the account number, you may use it to locate a tax bill for the property you have recently purchased.
If you need further assistance please contact the St. Mary's County Treasurer's Office at 301-475-4200 extension *3300
