Any term used in this chapter that is not otherwise defined in this chapter has the same meaning as when used in a comparable context in laws of the United States relating to federal income taxation or in Title LVII of the Revised Code, unless a different meaning is clearly required. Except as provided in section 718.81 of the Revised Code, if a term used in this chapter that is not otherwise defined in this chapter is used in a comparable context in both the laws of the United States relating to federal income tax and in Title LVII of the Revised Code and the use is not consistent, then the use of the term in the laws of the United States relating to federal income tax shall control over the use of the term in Title LVII of the Revised Code.
Except as otherwise provided in section 718.81 of the Revised Code, as used in this chapter:
Any item of income that is exempt income of a pass-through entity under division (C) of this section is exempt income of each owner of the pass-through entity to the extent of that owner's distributive or proportionate share of that item of the entity's income.
A publicly traded partnership that is treated as a partnership for federal income tax purposes and that is subject to tax on its net profits in one or more municipal corporations in this state may elect to be treated as a C corporation for municipal income tax purposes. The publicly traded partnership shall make the election in every municipal corporation in which the partnership is subject to taxation on its net profits. The election shall be made on the annual tax return filed in each such municipal corporation. The publicly traded partnership shall not be required to file the election with any municipal corporation in which the partnership is not subject to taxation on its net profits, but division (D)(5) of this section applies to all municipal corporations in which an individual owner of the partnership resides.
If the taxpayer is not a C corporation, is not a disregarded entity that has made the election described in division (L)(2) of this section, is not a publicly traded partnership that has made the election described in division (D)(5) of this section, and is not an individual, the taxpayer shall compute adjusted federal taxable income under this section as if the taxpayer were a C corporation, except guaranteed payments and other similar amounts paid or accrued to a partner, former partner, shareholder, former shareholder, member, or former member shall not be allowed as a deductible expense unless such payments are a pension or retirement benefit payment paid to a retired partner, retired shareholder, or retired member or are in consideration for the use of capital and treated as payment of interest under section 469 of the Internal Revenue Code or United States treasury regulations. Amounts paid or accrued to a qualified self-employed retirement plan with respect to a partner, former partner, shareholder, former shareholder, member, or former member of the taxpayer, amounts paid or accrued to or for health insurance for a partner, former partner, shareholder, former shareholder, member, or former member, and amounts paid or accrued to or for life insurance for a partner, former partner, shareholder, former shareholder, member, or former member shall not be allowed as a deduction.
Nothing in division (E) of this section shall be construed as allowing the taxpayer to add or deduct any amount more than once or shall be construed as allowing any taxpayer to deduct any amount paid to or accrued for purposes of federal self-employment tax.
