Required reporting

Sec. 1. (a) Annual returns are required to be filed with the department by every taxpayer subject to the FIT, including any taxpayer which

has a loss for that taxable year. A unitary group is required to file only one (1) return covering all members of the unitary group. A schedule of all

members of the unitary group must be attached to the annual return. A copy of the taxpayer's federal income tax return which has been filed with

the Internal Revenue Service for the same taxable year must accompany the Indiana annual return.

(b) The annual return must be filed with the department on or before the fifteenth day of the fourth month following the close of the taxable

year. The department will recognize an extension of time which has been granted by the Internal Revenue Service, provided that such extension of

time can be verified through the Internal Revenue Service, and a copy of the federal application for extension of time is attached to the Indiana annual

return.

(c) If an additional extension period is needed for purposes of filing Indiana's annual return, and such time exceeds the federal extension

period granted, the taxpayer is required to file a petition for a separate Indiana extension of time in accordance with IC 6-8.1-6-2

[IC 6-8.1-6-2 was repealed by P.L.137-2022, SECTION 86, effective January 1, 2023.].

(d) Each taxpayer shall report and submit a quarterly estimated tax payment to the department equal to twenty-five percent (25%) of the

taxpayer's total estimated tax liability for the taxable year. The quarterly estimated payment is due on or before the last day of the month following

the close of each quarter of the taxable year.

(e) Failure to make quarterly estimated payments at least equal to:

(1) twenty percent (20%) of the final tax liability for the taxable year; or

(2) twenty-five percent (25%) of the final tax liability for the taxpayer's previous taxable year;

will result in a ten percent (10%) penalty imposed upon the difference between the actual amount paid and the amount required to be paid for

each quarter.
