Fees, deadlines, and delinquent taxes
Debit or credit card payments made in person, online, or by phone are assessed a service fee of approximately 2.5% of the payment amount, with a minimum $2.00 service fee. Electronic check or online check payments have a flat $1.49 service fee. These fees are charged by the payment processing company and cannot be waived by Frederick County.
Tax bills are mailed in July each year and in January for the half year levy. Interest begins to accrue on any unpaid account balance on October 1 at a rate of 1% per month. Unpaid taxes become delinquent in March and are subject to additional interest and penalties until paid in full.
Important: Failure to receive a bill does not remove the taxpayer’s responsibility to pay taxes, fees, interest, or penalties.
Partial payments and tax lien sale timing
Frederick County does not offer a formal payment plan, but the Treasury Department accepts partial payments of real estate tax bills. Taxpayers may pay any amount at times they choose until the Friday before the annual tax lien sale in May.
Interest continues on any unpaid balance, and delinquency, advertising, and tax sale dates still apply. The Frederick County tax sale is an internet-based auction using the high bid premium method and is held on the second Monday in May. Tax sale properties are advertised in a local newspaper and on the county website approximately 30 days before the sale.
Property owners and bidders can review Frederick County tax sale information for tax sale schedules, notices, listings, registration, and related materials.

Frederick County publishes current and historical tax rates, including real property rates for the State, County, Frederick City differential, Myersville differential, municipalities, lighting districts, and system benefit charge fee rates.
For the 2025-2026 tax year, the real property rate shown for the State is 0.112 per $100 of assessed value, and the County rate shown for most properties is 1.110 per $100 of assessed value. Properties in Frederick City or Myersville use the differential rates shown by the county.

Assessment questions and lien certificate requests
Questions about a property assessment should go to the State Department of Assessments and Taxation. Questions about a Frederick County tax bill should go to the Treasury Department.
For lien certificates or tax status reports, Frederick County requires a separate request for each parcel or property number. The request has a $20.00 fee plus a convenience fee, and the county asks users to allow 3 business days for completion. Charges owed to a municipality are not reflected and must be satisfied before transfer.
Use the county’s lien certificate and tax status report request page for instructions on that process.
Third party notification program
Frederick County offers a pilot third party notification program for homeowners who are at least 65 years of age or are disabled. The program lets an eligible homeowner designate someone to receive copies of the real estate tax bill.
The third party is not responsible for taxes or delinquencies. Their role is to check that the property owner received the tax notices and to encourage prompt payment. Completed applications may be submitted to the Treasury Department by email or to 30 N. Market St. Frederick, MD 21701.
Eligible homeowners can review the third party notification program details before applying.
