OH HB615

Amends section 5747.05 of the Ohio Revised Code to modify the computation method for the personal income tax joint filer credit for married couples filing joint returns.

For taxable years 2023 and earlier, provides a nonrefundable credit equal to the lesser of $650 or a percentage (5%-20%) of tax due based on modified adjusted gross income brackets ranging from $25,000 or less to more than $75,000.

For taxable years 2024 and later, changes the credit calculation to the difference between the joint return tax amount and the "minimum combined amount of tax" (the sum of what spouses would owe if filing separately, with adjustments claimed to minimize combined tax).

Defines "minimum combined amount of tax" as calculated using both spouses' adjustments and credits claimed in the manner that results in the least combined tax due.

Requires the tax commissioner to issue rules for supporting documentation and information needed to claim the credit.
