Sec. 4. (a) A tax shall be imposed on the adjusted gross income of an electing entity for the taxable year of the election. The adjusted gross income of the electing entity shall be the aggregate of the direct owners’ share of the electing entity’s adjusted gross income. For purposes of this section:

(1) the electing entity shall determine each nonresident direct owner’s share after allocation and apportionment pursuant to IC 6-3-2-2; and

(2) the electing entity shall determine the resident direct owner’s share either before allocation and apportionment pursuant to IC 6-3-2-2 or after allocation and apportionment pursuant to IC 6-3-2-2. The electing entity must use the same method for all resident direct owners.

     (b) The tax rate shall be the tax rate specified in IC 6-3-2-1(b) as of the last day of the electing entity’s taxable year, and the tax shall be due on the same date as the entity return for the taxable year is due under this article, without regard to extensions.

     (c) On its return for the taxable year, the electing entity shall attach a schedule showing the calculation of the tax and the credit for each direct owner, and remit the tax with the return, taking into account prior estimated tax payments and other tax payments by the electing entity, along with other payments that are credited to the electing entity as tax paid under this chapter or as tax withheld under IC 6-3-4 or IC 6-5.5-2-8. The department may prescribe the form for providing the information required by this section.

     (d) If a pass through entity makes estimated tax payments, makes other tax payments, or has other payments that are credited to the electing entity as tax paid under this chapter or a tax withheld under IC 6-3-4 or IC 6-5.5-2-8, and the pass through entity does not make the election under section 3 of this chapter, the pass through entity:

(1) may treat pass through entity tax remitted on its behalf under this chapter as pass through entity tax to its direct owners, provided that:

(A) the tax is designated on a schedule similar to the schedule required under subsection (c) and is reported to the direct owners in the manner provided in section 5 of this chapter; and

(B) the pass through entity credits an amount to a direct owner no greater than the tax that otherwise would be due under this chapter on their share of the adjusted gross income from the pass through entity or the direct owner’s portion (as determined under subsection (a)) of the pass through entity tax passed through to the pass through entity, whichever is greater (for purposes of this clause, a trust or estate shall compute the tax in the same manner as an electing entity);

(2) shall treat any payment other than a payment designated under subdivision (1) as a withholding tax payment under IC 6-3-4-12, IC 6-3-4-13, IC 6-3-4-15, or IC 6-5.5-2-8 to the extent the pass through entity otherwise has not remitted or been credited with such withholding; and

(3) may request a refund of any payment in excess of the amounts credited or designated under subdivision (1) or (2).

     (e) If a pass through entity elects to be subject to tax under this chapter and the pass through entity determines that its tax is less than the pass through entity tax that is paid on its behalf, the pass through entity may treat the tax paid on its behalf in a manner similar to subsection (d). However, the pass through entity may not treat an amount less than its own liability under this chapter as pass through entity tax under subsection (d)(1).
