Indiana Code Title 6. Taxation § 6-3.6-3-2

Sec. 2. (a) An adopting body or, if authorized by this article, another governmental entity that is not an adopting body, may take an action under this article only by ordinance, unless this article permits the action to be taken by resolution.

(b) The department of local government finance, in consultation with the department of state revenue, may make electronically available uniform notices, ordinances, and resolutions that an adopting body or other governmental entity may use to take an action under this article.  An adopting body or other governmental entity may submit a proposed notice, ordinance, or resolution to the department of local government finance for review not later than thirty (30) days prior to the date that the adopting body or governing body intends to submit the notice, adopting ordinance or resolution, and vote results on an ordinance or resolution under subsection (d).  If the adopting body or other governmental entity wishes to submit the proposed notice, ordinance, or resolution to the department of local government finance for review, the adopting body or other governmental entity shall submit the proposed notice, ordinance, or resolution to the department of local government finance on the prescribed forms. The department of local government finance shall provide to the submitting entity a determination of the appropriateness of the proposed notice, ordinance, or resolution, including recommended modifications, within thirty (30) days of receiving the proposed notice, ordinance, or resolution.

(c) An ordinance or resolution adopted under this article must comply with the notice and hearing requirements set forth in IC 5-3-1.

(d) The department of local government finance shall prescribe the procedures to be used by the adopting body or governmental entity for submitting to the department the notice, the adopting ordinance or resolution, and the vote results on an ordinance or resolution.  The department of local government finance shall notify the submitting entity within thirty (30) days after submission whether the department has received the necessary information required by the department.  A final action taken by an adopting body or governmental entity under this article to impose a new tax or amend an existing tax is not effective until the department of local government finance notifies the adopting body or governmental entity that it has received the required information from the submitting entity.
