Maryland Department of Assessments and Taxation

Real Property Division Real property is reassessed on a three-year cycle by reviewing one-third of all property in Maryland every year. The review includes an exterior physical inspection of the property. The Real Property Valuation Division participates in all appeals court proceedings where assessment questions are involved. Assessments are certified by the Department to local governments where they are converted into property tax bills by applying the appropriate property tax rates. An assessment is based on an appraisal of the fair market value of the property. An appraisal is an estimate of value. There are three accepted approaches to market value: (1) the sales approach; (2) the cost approach; (3) the income approach. While differing in the method of calculation each approach is designed to indicate the property’s fair market value. The property tax is primarily a local government revenue. Counties and cities depend on the property tax and a portion of the income tax to make up their budgets.


Taxpayer Services Division

The Taxpayer Services’ Corporate Charter/Charter Legal Review unit is custodian of documents relating to the organization and ownership of many types of business entities that are required to file documents with the State. These documents include charters for Maryland corporations and qualifications and registrations for foreign corporations. The unit is also the custodian of security interest (UCC) filings.

Charter Legal processes ground rent redemptions. Under this program homeowners can redeem the ground rents on their residencies where the ground rent holder can not be located. The unit also implemented a ground rent registration system where ground rent lease holders can register their ground rents with the State.

Taxpayer Services oversees the annual reassessment of operating property of railroads and public utilities and personal property of businesses. Property tax reports are filed with, and reviewed by, the Division annually. Thereafter, the values are certified to the subdivisions so that they may issue tax bills.

The Division administers franchise taxes applicable to the gross receipts of public service corporations.
