Turbotax is using 10% of my tax to calculate the Ohio joint filing credit. The Ohio table clearly shows that if your modified adjusted gross income is above $75,000 then this is 5%. My Ohio adjusted gross income in $76,367 (line 3). I have 2 exemptions ($4,300) for an Ohio income tax base of $72,067 (line 7). It seems clear that this credit is based on the adjusted gross income, not the income tax base. Am I wrong? Is Turbotax wrong? (Note: with no business deductions your modified adjusted gross income equals your Ohio adjusted gross income. Other credits do use the income tax base instead of the adjusted gross income such as the senior citizen credit, but not so for the joint filing credit)
