Ohio Rev. Code § 5733.41
The purpose of the tax imposed by this section is to complement and to reinforce the tax imposed under section 5733.06 of the Revised Code.
For the same purposes for which the tax is levied under section 5733.06 of the Revised Code, there is hereby levied a tax on every qualifying pass-through entity having at least one qualifying investor that is not an individual. The tax imposed by this section is imposed on the sum of the adjusted qualifying amounts of the qualifying pass-through entity's qualifying investors, that are neither individuals nor subject to division (G)(2) of section 5733.01 of the Revised Code, at a rate equal to the tax rate imposed on taxable business income under division (A)(4)(a) of section 5747.02 of the Revised Code.
The tax imposed by this section applies only if the qualifying entity has nexus with this state under the Constitution of the United States for any portion of the qualifying entity's qualifying taxable year, and the sum of the qualifying entity's adjusted qualifying amounts exceeds one thousand dollars for the qualifying entity's qualifying taxable year. This section does not apply to a pass-through entity if all of the partners, shareholders, members, or investors of the pass-through entity are taxpayers for the purposes of section 5733.04 of the Revised Code without regard to section 5733.09 of the Revised Code for the entire qualifying taxable year of the pass-through entity.
If, prior to the due date of the return, a qualifying pass-through entity receives from an investor a written representation, under penalties of perjury, that the investor is described in division (I)(1), (2), (6), (7), (8), or (9) of section 5733.40 of the Revised Code for the qualifying pass-through entity's entire qualifying taxable year, the qualifying pass-through entity is not required to withhold or pay the taxes or estimated taxes imposed under this section or sections 5747.41 to 5747.453 of the Revised Code with respect to that investor for that qualifying taxable year, and is not subject to any interest or interest penalties for failure to withhold or pay those taxes or estimated taxes with respect to that investor for that qualifying taxable year.
If, prior to the due date of the return, a qualifying trust receives from a beneficiary of that trust a written representation, under penalties of perjury, that the beneficiary is a resident taxpayer for the purposes of Chapter 5747. of the Revised Code for the qualifying trust's entire qualifying taxable year, the qualifying trust is not required to withhold or pay the taxes or estimated taxes imposed under this section or sections 5747.41 to 5747.453 of the Revised Code with respect to that beneficiary for that qualifying taxable year, and is not subject to any interest or interest penalties for failure to withhold or pay those taxes or estimated taxes with respect to that beneficiary for that qualifying taxable year.
The tax commissioner may adopt rules for the purpose of the tax levied by this section or section 5747.41 of the Revised Code, including a rule defining "qualifying investor" or "qualifying beneficiary," and a rule requiring or permitting a qualifying entity to combine its income with related members and to pay the tax and estimated tax on a combined basis.
Sections 5747.10 to 5747.19 and 5747.42 to 5747.453 of the Revised Code apply to a qualifying entity subject to the tax imposed under this section.
The levy of the tax under this section does not prevent a municipal corporation or a joint economic development district created under section 715.70, 715.71, or 715.72 of the Revised Code from levying a tax on income.
