Annual tax bills and the first installment of semi-annual bills are due on or before September 30th and become delinquent on October 1st. The second semi-annual installment is due December 31st and becomes delinquent January 1st.
Delinquent tax bills are subject to interest and penalty at the rate of 1 2/3% (1.667 per month on the unpaid balance) per month until paid in full. The total late charge is 20% annually as set by Resolution following County Council action, and which is composed of 8% interest and 12% penalty. Interest and penalty are calculated on the net amount of the bill, after any credits are applied.
Delinquent taxes will result in the sale of the property tax lien through a public tax lien sale on the second Monday in June of the subsequent calendar year. Taxpayers receive a delinquency or tax lien sale notice in April. Accounts eligible for the tax lien sale are listed for four consecutive weeks preceding the tax lien sale in a Montgomery County newspaper and are subject to a $50 advertising fee. Property tax accounts taken to tax lien sale may be subject to additional legal costs that are incurred by the new tax lien certificate holder.
