Updated October 24, 2026. Quick answer: Line 4 of the 2025 Ohio Schedule of Credits is the senior citizen credit. The instructions say “The credit is equal to $50 per return.” It has three conditions, including age 65 or older at the end of the tax year.
What this line asks
The form labels line 4 “Senior citizen credit (must be 65 or older to claim this credit)”. The instructions introduce it with one sentence: “To qualify, all of the following must be true:”
Who it applies to
All three conditions must hold. “Your MAGI less exemptions is less than $100,000”; “You were 65 or older at the end of the tax year”; and “You have not previously taken the Ohio lump sum distribution credit.”
The booklet defines the first test’s key term this way: “Modified adjusted gross income (MAGI) is your Ohio adjusted gross income (Ohio IT 1040, line 3) plus your business income deduction (Ohio Schedule of Adjustments, line 13).” Retirees who have taken or plan to take a lump sum should also see the lump sum credit on line 5, and the retirement income credit on lines 2 and 3 is covered on the Ohio retirement income credit page.
What the instructions say to enter
| Step | What the instructions say |
|---|---|
| Check the lead-in | “To qualify, all of the following must be true:” |
| Income test | “Your MAGI less exemptions is less than $100,000” |
| Age test | “You were 65 or older at the end of the tax year” |
| Prior credit test | “You have not previously taken the Ohio lump sum distribution credit.” |
| Amount | “The credit is equal to $50 per return.” |
The figures the line prints
Two figures sit inside single running bullets or sentences: “Your MAGI less exemptions is less than $100,000”, and “The credit is equal to $50 per return.” A related line carries a warning: “If you take this credit, you cannot take the $50 senior citizen credit on this year’s return or any future return.”
Where the result goes next
On the form, the credits are added on line 10, which is labeled “Total (add lines 2 through 9)”. For the broader Ohio retirement picture, see Ohio retirement taxes and whether Ohio taxes pensions.

Common mistakes
- Claiming the credit before turning 65. The instructions list this condition: “You were 65 or older at the end of the tax year”.
- Claiming it after using the lump sum credit. The instructions say “You have not previously taken the Ohio lump sum distribution credit.”
- Ignoring the income test. The instructions say “Your MAGI less exemptions is less than $100,000”.
