Ohio Joint Filing Credit

[PBTaxman58]

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)

 Are you factoring in the local tax rates as well?

What does the local tax rate have to do with it ?  Ohio taxes start with your Federal adjusted gross income.  No where do local taxes come into the equation.  I now truly believe that TurboTax has an error in their software.  The joint filing credit is Ohio's way of fixing the issue of combining two incomes into one for taxation purposes.  Without it, this means a single filer or a married filer pay exactly the same tax amount.  So the question is -  what number is TurboTax using to calculate 10%?  If it uses the Ohio modified adjusted gross ($76,000), like it should, then this would be 5%.  If TurboTax is using the Ohio tax base figure ($72,000), than it would be 10%.   I just happen to straddle $75,000 with each of those numbers.  Considering that Ohio has millions of taxpayers, and quite a few use Turbotax, there surely are many others who also fit this scenario.  TurboTax needs to investigate this quickly.  In the mean time, I am using Ohio's I-file to check.  However they seem to have a problem too.  Ohio is giving me no credit, $0, where Turbotax is giving me 10% credit.  I enter no W-2's and live strictly on my IRA,  Withdrawals from an IRA clearly count as "qualified income" as stated in the Ohio tax instructions.  AAARRRRGHHH !
