Why is the Ohio tax box not adjusting when earning a credit for filing jointly on state tax return?

[Hal_Al · Accepted solution]

Don't go by the refund meter (tax box).

Check your actual tax form. The Joint filing Credit is on line 13 of the Ohio Schedule of Credits.. If you're not getting it, check the Joint Filing Credit Allocation Worksheet.

This is where your net qualifying income is calculated. It shows on line 4. If either of you is less than $500 on line 4, you do not qualify.
