(1)(a) Returns required by this code shall be filed with the office of the department in Leon County or at such other place as the department may by regulation prescribe. All returns required for a DISC (Domestic International Sales Corporation) under s. 6011(c)(2) of the Internal Revenue Code shall be filed on or before the 1st day of the 10th month after the close of the taxable year; all partnership information returns shall be filed on or before the 1st day of the 4th month after the close of the taxable year; and all other returns shall be filed on or before the 1st day of the 5th month after the close of the taxable year or the 15th day after the due date, without extension, for the filing of the related federal return for the taxable year, unless under subsection (2) one or more extensions of time, not to exceed 6 months in the aggregate, for any such filing is granted.

(b) Notwithstanding paragraph (a), for taxable years beginning before January 1, 2026, returns of taxpayers with a taxable year ending on June 30 shall be filed on or before the 1st day of the 4th month after the close of the taxable year or the 15th day after the due date, without extension, for the filing of the related federal return for the taxable year, unless under subsection (2) one or more extensions of time for any such filing is granted.

(2)(a) When a taxpayer has been granted an extension or extensions of time within which to file its federal income tax return for any taxable year, and if the requirements of s. 220.32 are met, the filing of a request for such extension or extensions with the department shall automatically extend the due date of the return required under this code until the expiration of 6 months from the original due date.

(b) The department may grant an extension or extensions of time for the filing of any return required under this code upon receiving a prior request therefor if good cause for an extension is shown.

An extension granted under this paragraph is not valid unless the taxpayer complies with s. 220.32.

(c) For purposes of this subsection, a taxpayer is not in compliance with s. 220.32 if the taxpayer underpays the required payment by more than the greater of $2,000 or 30 percent of the tax shown on the return when filed.

(d) For taxable years beginning before January 1, 2026, the 6-month time period in paragraphs (a) and (b) shall be 7 months for taxpayers with a taxable year ending June 30.
