Obligation to pay property taxes is not stayed or suspended pending an appeal regarding the assessment. Property taxes are due even if there is an appeal in progress. If the original property tax bill has been paid in full and the assessment is reduced and creates a refund, the refund will be sent automatically. If a refund is not received, please submit a refund claim form to the Division of Treasury at 255 Rockville Pike, Suite L-15, Rockville, MD 20855.
