Payments from One Party

Overpayments in excess of $10 are automatically refunded and a request is not necessary.   (In lieu of a refund, the overpayment may be credited to any outstanding property tax liability of the paying party).

Payments from Two Parties

When we receive double-payments from different parties, Tax Accounting notifies both parties.  To receive a refund, one of the paying parties must submit a  DART Refund Request Form (48.35 KB) with a reason for the error and where the refund should be sent.

DART Refund Request Form (48.35 KB) and any additional information required must be received by the 5th of the month in order to be refunded that month.

Refunds Issued Monthly

Refund checks are issued once per month and sent via US mail. Checks are usually mailed around the 15th of the month.

Due to the volume of requests, we cannot guarantee that a refund will be issued by a specific date.
