Ohio Retirement Income Credit and Schedule of Adjustments for Surviving Spouses

After a spouse dies, tax season arrives with a new layer of complexity: different income sources, a changed filing status, and a set of Ohio-specific deductions that don't appear on the federal return at all. Two of the most commonly missed benefits are the Ohio Retirement Income Credit and the deduction available through Ohio's Schedule of Adjustments. Together, they can reduce a surviving spouse's Ohio tax liability by hundreds of dollars each year — but only if you know to claim them.

Ohio Does Not Tax Social Security Benefits — But You Must Claim the Deduction

Ohio is one of the states that does not impose income tax on federal Social Security benefits. However, the exemption is not automatic. If your Social Security income shows up as taxable on your federal return, it will carry into your Ohio adjusted gross income calculation unless you actively remove it.

The mechanism is the Ohio Schedule of Adjustments (also called the IT BUS schedule in some years), which is completed as part of your Ohio IT 1040 return. There is a specific line for "taxable Social Security benefits" that allows you to deduct the amount that was taxable at the federal level from your Ohio adjusted gross income. Skip this line and you'll pay Ohio income tax on income the state specifically intended to exempt.

This matters most in the year a spouse dies and in subsequent years when the surviving spouse may have received both their own Social Security benefit and a survivor benefit from the deceased's record. Both amounts need to be accounted for when determining how much to deduct on the Schedule of Adjustments.

Other Deductions Available on the Ohio Schedule of Adjustments

The Schedule of Adjustments contains several other subtractions from Ohio gross income that surviving spouses frequently miss:

Military retirement pay: If the deceased spouse served in the military and the surviving spouse is receiving survivor benefit plan (SBP) payments tied to military retirement, these may be deductible from Ohio adjusted gross income. Certain military disability pay is also fully deductible regardless of the income amount.

Ohio National Guard and reserve pay: If the surviving spouse is themselves a member of the Ohio National Guard or reserves, active duty pay earned within Ohio is excluded.

Interest on U.S. obligations: Interest income from U.S. Treasury bonds, notes, and savings bonds is taxable federally but deductible on the Ohio Schedule of Adjustments.

These adjustments reduce your Ohio adjusted gross income, which then flows into the calculation for the Retirement Income Credit.

The Ohio Retirement Income Credit

The Ohio Retirement Income Credit is a direct reduction of your Ohio income tax — not a deduction from income, but a credit applied after your tax is calculated. The credit is worth up to $200 per return, and it applies to qualifying retirement income received during the year.

Qualifying retirement income includes:

• Pension income from OPERS, STRS, SERS, OP&F, or other public retirement systems
• Distributions from IRAs and 401(k) accounts
• Annuity income
• Railroad retirement benefits
• Social Security benefits (even though they're deducted on the Schedule of Adjustments, they still count toward qualifying retirement income for this credit)

Income limit: The credit is available to taxpayers whose Ohio modified adjusted gross income is below $100,000. Above this threshold, the credit phases out and is not available.

Credit calculation: The actual credit amount scales with how much retirement income you receive:

Most surviving spouses receiving OPERS or STRS pension payments, Social Security survivor benefits, or IRA distributions will be in the $8,000+ tier and qualify for the full $200 credit.

How These Two Benefits Work Together

The sequence matters: the Schedule of Adjustments reduces your Ohio adjusted gross income first, which can affect your eligibility for other income-based programs like the homestead exemption (capped at $41,000 MAGI). Then the Retirement Income Credit reduces the actual tax you owe.

For a surviving spouse receiving $18,000 in Social Security and $12,000 in OPERS pension annually:

1. Ohio adjusted gross income starts at $30,000 (federal AGI)
2. Subtract $15,300 in federally taxable Social Security on Schedule of Adjustments → Ohio AGI drops to $14,700
3. Calculate Ohio income tax on $14,700 (after standard deductions)
4. Apply the $200 Retirement Income Credit to the resulting tax bill

The combined effect of the Social Security deduction and the credit can eliminate most or all of the Ohio tax liability for survivors living primarily on retirement income.

Filing Considerations in the Year of Death

The year a spouse dies involves two separate tax situations:

Final joint return (if applicable): If the death occurred during the tax year, you can generally still file a joint Ohio return (IT 1040) for that year. Both spouses' income from January 1 through the date of death is included on the joint return.

Qualifying surviving spouse status: For the two tax years following the death, if you have a dependent child living at home, you may qualify for "qualifying surviving spouse" filing status federally, which uses the married filing jointly rates. Ohio conforms to federal filing status definitions.

Estate income: If the estate generated income (interest, rental income, investment gains) after the date of death and before distribution to heirs, that income must be reported on the Ohio Fiduciary Income Tax Return (Form IT 1041), not on the surviving spouse's personal return. Ohio follows the "credits follow the distribution" principle — tax credits pass through to beneficiaries when income is distributed to them, rather than being retained by the estate.

Who Should Review These Filings

The Schedule of Adjustments and Retirement Income Credit are straightforward enough for most surviving spouses to handle independently, particularly with tax software. However, consider consulting a CPA if:

• The estate has its own income requiring Form IT 1041 alongside your personal IT 1040
• You received a mix of pension distributions, IRA rollovers, and survivor benefits in the same year, creating classification questions
• You're within range of the $41,000 MAGI homestead exemption threshold and the Schedule of Adjustments deduction could push you under the limit

A one-hour session with a CPA to review these specific Ohio adjustments typically costs far less than the potential tax savings from correctly applying the deductions and credits.

These Ohio tax benefits are part of a broader set of financial protections that surviving spouses can claim — but most require affirmative action to activate. The Ohio Survivor Benefits Navigator maps out all the steps, deadlines, and forms across probate, vehicle transfers, pensions, and tax filings so nothing falls through the cracks.
