Payments received in person, via our secure payment box or postmarked after the May 2 deadline are automatically charged 1% interest on outstanding balances.  PLEASE plan ahead to avoid interest charges. Our secure payment drop box is located at the Court House entrance on the Sheriff side of the building.  If mailing your payment, the envelope must be federally postmarked on or before May 2 for the payment be considered on time. Keep in mind, although you place your payment in the mailbox, federal postmarks often happen the next business day. If mailing your payment less than a week prior to the deadline, we strongly recommend having your envelope hand canceled by the postal agent.
