Appealing an assessment
Use the valuation notice and the county’s published protest guidance to determine the last day to file. Do not assume the payment deadline controls the appeal.
Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.
Submit through the official channel, save the confirmation, and attend the board or review hearing if one is scheduled. An appraiser or attorney can help evaluate evidence when the value or stakes are substantial.
The verified protest guidance for this county is: Within 45 days of the date on the Maryland SDAT Notice of Assessment; Harford County states assessment appeals go to the Property Tax Assessment Appeals Board. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
