OH SB210

Amends Ohio Revised Code section 5747.05 to modify the joint filer income tax credit calculation for taxable years beginning on or after January 1, 2021.

Changes the joint filer credit from a fixed $650 maximum to a percentage-based credit ranging from 5% to 20% based on modified adjusted gross income less exemptions, with maximum credit capped at $650.

Credit percentage tiers: 20% for income of $25,000 or less; 15% for $25,000-$50,000; 10% for $50,000-$75,000; and 5% for income over $75,000.

Credit is calculated as the lesser of $650 or the applicable percentage of the difference between joint return tax liability and the combined tax that would be due if spouses filed separate returns.

Defines key terms including "minimum combined amount of tax," "adjustment," and "credit," and requires credit to follow the order specified in section 5747.98 of the Revised Code.
