The Maryland Department of Assessments and Taxation is a customer-focused agency that works to ensure property is accurately assessed, business records are appropriately maintained, and necessary tax-related information is conveyed to state agencies and local jurisdictions. The Department's responsibilities can generally be split into three main areas: Business Services, Real Property and Tax Credits.

The Real Property Division values more than two million residential and commercial property accounts throughout the state. Those values are then certified to local governments, which use the assessments to collect property taxes. The Department is committed to ensuring uniform and accurate assessments statewide, as well as providing a fair and prompt appeal process.

The Business Services Division is comprised of the Business Charter, Business Property, and Tax Cr​edit Units. The Business Charter Unit helps create businesses and ensures that the documents they file meet the requirements of Maryland law. The Business Property Unit values items that businesses own, lease, or use in order to operate and are subject to taxation by local jurisdictions. The Tax Credit Unit helps administer certain tax credits, including the homeowners'​ tax credit, the renters'​ tax credit, and the homestead tax credit.​
