Please remember to fill out the middle portion of the application.Use this application if you refunded documentary stamp tax or nonrecurring intangible personal property tax to a customer who paid tax that was not due. To request a tax refund, file an Application for Refund - Sales and Use Tax (Form DR-26S) or Application for Refund - All Other Taxes (Form DR-26). Report an overpayment. Complete an overpayment refund form to notify First Coast of an overpayment prior to receiving a demand letter. Submit this completed form with all refund checks and supporting documentation to ensure the overpayment refund is processed timely. The Benefit Recovery Unit reviews the case and establishes a claim if an overpayment has indeed occurred.
