2. (c) For a state or local tax that is imposed on a transaction and that is required to be remitted by a person or an entity to the state or local unit as an agent or a trustee of the state or local unit the state or local tax shall be computed on the total transaction amount, as defined in IC 23-15-13-3 , prior to any rounding requirement required by IC 23-15-13 .

   1. (1) not imposed on a transaction but is required to be withheld by a person or entity acting as an agent or trustee for the state or a local unit; or

   2. (2) otherwise included in a total transaction amount as defined in IC 23-15-13-3 ;

      the state or local tax withheld or included shall be computed without rounding and, if applicable, the total transaction amount, as defined in IC 23-15-13-3 , shall be rounded in the manner provided under IC 23-15-13-4 .

4. (e) For purposes of this section, the following apply:

   1. (1) The aggregate amount of a state or local tax described in subsection (c) or (d) remitted by a person or entity, reduced by any collection allowances or similar amounts permitted to be retained by the person or entity, shall be subject to the rounding provisions described in subsections (a) and (b).
   2. (2) If multiple state or local taxes are required to be reported on a single form, the rounding of a remittance under subsection (a) or (b) shall be applied to the total state or local tax amount resulting from the computation on the form and the remittance period.
   3. (3) For state or local taxes not described in subdivision (2), the rounding of a state or local tax remittance described in subsection
   4. (a) or (b) shall be determined separately for each state or local tax type and for each remittance period.
   5. (4) If a state or local tax liability is reported in the manner provided under subdivision (2), but the state or local unit determines a separate liability from other state and local taxes, subdivision (3) applies to the payment of the separate liability.
5. (f) For purposes of subsections (c) and (d), if multiple state or local taxes are required to be paid, each state or local tax shall be computed separately and, if applicable, the total transaction amount as defined in IC 23-15-13-3 shall be computed including all state or local taxes required to be paid on the total transaction amount.
