(c) Extension of due date to November 15. Except for a taxable entity that has been notified by the comptroller that it is required to make its franchise tax payments by electronic funds transfer (see subsections (d), (f), and (g) of this section), a taxable entity will be granted an extension to file an annual report and the due date of the report is extended to the next November 15, if the taxable entity:

  (2) requests the extension on a form provided by the comptroller; and
  (3) remits with the extension request:
    (A) 90% or more of the amount of tax reported as due on the report filed on or before November 15; or
    (B) 100% of the tax reported as due for the previous calendar year on the report due in the previous calendar year and filed on or before May 14 of the year for which the extension is requested.
      (i) For reports originally due prior to January 1, 2017, a combined group may only use this 100% option if the combined group has lost a member or if the members of the combined group are the same as they were on the last day of the period upon which the report due in the previous calendar year was based.
      (ii) For reports originally due on or after January 1, 2017, a combined group may use this 100% option regardless of any changes in combined group members.
      (iii) A separate entity that was included in a combined group report originally due in the previous calendar year may not use the 100% extension option.
(d) No previous report. An extension shall not be granted under subsection (c)(3)(B) or (f)(3)(B) of this section, if no report was due in the previous calendar year or the report due in the previous calendar year is not filed on or before May 14 of the year for which the extension is requested.
(e) Penalty and interest for taxable entities not required to pay by electronic funds transfer. Penalty and interest, except for a taxable entity that has been notified by the comptroller that it is required to make its franchise tax payments by electronic funds transfer (see subsection (h) of this section), will be calculated in the following manner.
  (1) If a taxable entity is granted an extension by remitting, on or before May 15, at least 100% of the tax reported as due for the previous calendar year on the report due in the previous calendar year and filed on or before May 14 of the year for which the extension is requested, then no penalty or interest will be assessed if the remaining tax due is remitted on or before November 15.
  (2) If a taxable entity is granted an extension by remitting, on or before May 15, 90% or more of the tax that will be reported as due on or before November 15, then no penalty or interest will be assessed if the remaining tax due is remitted on or before November 15.
  (3) If a taxable entity, on or before May 15, requests an extension but does not meet the requirements of paragraph (1) or (2) of this subsection, then penalty and interest will be assessed on the difference between 90% of the tax finally determined to be due and the amount remitted on or before May 15. Penalty and interest will also be assessed on 10% of the tax finally determined to be due if not remitted on or before November 15.
(f) Required electronic funds transfer extension of the due date to August 15. Subject to paragraphs (1) - (3) of this subsection, a taxable entity that has been notified by the comptroller that it is required to make its franchise tax payments by electronic funds transfer (see §3.9 of this title (relating to Electronic Filing of Returns and Reports; Electronic Transfer of Certain Payments by Certain Taxpayers)) will be granted an extension to file an annual report and the due date of the report is extended to the next August 15. A combined group is required to make its franchise tax payments by electronic funds transfer if any member of the combined group receives notice of the requirement. An extension of the due date to August 15 will be granted if the taxable entity:
  (1) requests the extension on or before May 15;
  (2) requests the extension on a form provided by the comptroller; and
  (3) remits with the extension request:
    (A) 90% or more of the amount of tax reported as due on the report filed on or before August 15; or
    (B) 100% of the tax reported as due for the previous calendar year on the report due in the previous calendar year and filed on or before May 14 of the year for which the extension is requested.
      (i) For reports originally due prior to January 1, 2017, a combined group may only use this 100% option if the combined has lost a member or if the members of the combined group are the same as they were on the last day of the period upon which the report due in the previous calendar year was based.
      (ii) For reports originally due on or after January 1, 2017, a combined group may use this 100% option regardless of any changes in combined group members.
      (iii) A separate entity that was included in a combined group report originally due in the previous calendar year may not use the 100% extension option.
(g) Required electronic funds transfer second extension of the due date to November 15. A taxable entity granted an extension under subsection (f) of this section will be granted an extension to file an annual report and the due date of the report is extended to the next November 15 if the taxable entity:
  (1) requests the extension on or before August 15;
  (2) requests the extension on a form provided by the comptroller; and
  (3) remits with the request the difference between the amount paid previously for the current reporting period and 100% of the amount of tax reported as due on the report filed on or before November 15.
(h) Penalty and interest for taxable entities required to pay by electronic funds transfer. Penalty and interest will be calculated in the following manner.
  (1) If a taxable entity is granted an extension until August 15 by remitting, on or before May 15, at least 100% of the tax reported as due for the previous calendar year on the report due in the previous calendar year and filed on or before May 14 of the year for which the extension is requested, then no penalty or interest will be assessed if the remaining tax due is remitted on or before August 15. However, if the taxable entity requests, on or before August 15, an extension until November 15, and remits, on or before August 15, at least 99% of the amount reported as due on or before November 15, then no penalty will be assessed. Interest will be assessed on the remaining tax due if not remitted on or before November 15.
  (2) If a taxable entity is granted an extension until August 15 by remitting, on or before May 15, 90% or more of the tax that will be reported as due on or before August 15, then no penalty or interest will be assessed if the remaining tax due is remitted on or before August 15. However, if the taxable entity requests, on or before August 15, an extension until November 15, and remits, on or before August 15, at least 99% of the amount reported as due on or before November 15, then no penalty will be assessed. Interest will be assessed on the remaining tax due if not remitted on or before November 15.
  (3) If a taxable entity, on or before May 15, requests an extension until August 15, but does not meet the requirements of paragraph (1) or (2) of this subsection, then penalty and interest will be assessed on the difference between 90% of the tax finally determined to be due and the amount remitted on or before May 15. Penalty and interest will also be assessed on 10% of the tax finally determined to be due if not remitted on or before August 15. However, if the taxable entity requests, on or before August 15, an extension until November 15, and remits on or before August 15 at least 99% of the amount reported as due on or before November 15, then penalty and interest will be assessed on the difference between 90% of the tax finally determined to be due and the amount remitted on or before May 15.
