If you're buying a home in Cincinnati this fall, the property tax figure on the listing describes the seller. It reflects the seller's credits, the seller's occupancy, and paperwork the seller filed. Until this year, that figure was a fair stand-in for what the next owner would pay, because Ohio treated an owner-occupied house and a rented one almost the same way. Under House Bill 186, that's no longer true. From tax year 2026 on, the gap between those two treatments grows every year, so the same brick two-family in Northside or Walnut Hills will carry a different bill depending on whether its owner lives there.
That matters most in the weeks around closing. That's when the old bill gets prorated, a conveyance form asks a question many buyers answer quickly, and a December 31 deadline either locks in a credit or doesn't.
Two Credits Moving In Opposite Directions
Ohio has long given residential property two percentage reductions. One was a 10% "nonbusiness" rollback that nearly every home received. The other was a 2.5% owner-occupancy reduction for people living in their own home. HB 186, effective March 20, 2026, phases out the first and expands the second. The nonbusiness rollback drops to 7.5% in tax year 2026, 5% in 2027, 2.5% in 2028, and zero in 2029. Over the same years, the owner-occupancy reduction rises to 5.70%, 8.92%, 12.15%, and then 15.38%.
The Ohio Legislative Service Commission's final analysis of HB 186 sums up the combined effect. The total credit for owner-occupied property goes from 12.5% to 15.38%, and the rollback disappears for residential property "leased to renters or otherwise not used as the owner's primary residence."
Adding the two statutory schedules together shows how the gap opens:
| Tax year (paid the following year) | Owner-occupied total reduction | Rented or non-primary residence | Gap between them |
|---|---|---|---|
| Before HB 186 | 12.5% | 10% | 2.5 points |
| 2026 | 13.2% | 7.5% | 5.7 points |
| 2027 | 13.92% | 5% | 8.92 points |
| 2028 | 14.65% | 2.5% | 12.15 points |
| 2029 onward | 15.38% | 0% | 15.38 points |
The gap used to be 2.5 points. By 2029 it will be more than six times that. Real property tax in Ohio is paid in arrears, so tax year 2026 changes show up on bills collected in 2027. Hamilton County collects real estate taxes twice a year, in February and July.
The Percentages Apply To Only Part Of The Bill
Both reductions apply only to taxes from "qualifying levies." Under Ohio Revised Code 319.302, those include levies approved at elections before September 29, 2013, levies within the ten-mill limit, and certain renewals and substitutes. The Hamilton County Auditor's levy explanation says additional or replacement levies passed on November 5, 2013 or later don't receive the rollback. HB 186 left that 2013 cutoff in place.
So a 15.38% owner-occupancy reduction is 15.38% of the qualifying portion, not of the whole bill. That portion depends on the parcel, the school district, and how much of the levy stack was passed after 2013. Hamilton County's parcel-level tax calculation lists the pieces separately, with lines for "Non Business Credit," "Owner Occupancy Credit," "Homestead," and "Sales Tax Credit." Those two credit lines are where the occupancy split will show up on a Cincinnati bill.
Why The Seller's Bill Misleads At Closing
Here is where the change gets in the way of a transaction. Ohio law says that once an owner-occupancy reduction has been filed, a transfer of ownership doesn't cancel it "for such year." A seller who lived in the house keeps the owner-occupancy credit on that tax year's bill after the sale. Because the bill is paid in arrears, that credit flows into the proration on the settlement statement.
A buyer who plans to rent the property out is reviewing a bill built on credits that won't carry into later years. The owner-occupancy reduction depends on the owner living there, and the nonbusiness rollback that rentals still get is shrinking every year. The Ohio Real Title guide to tax prorations explains that Ohio closings use either a short or a long proration method, and the purchase contract decides which one applies. Neither method projects the buyer's future occupancy onto the old bill.
The reverse case catches buyers too. If a landlord sells to someone who will live in the home, the seller's bill shows no owner-occupancy credit. That makes the house look more expensive to own than it will be, but only if the new owner files.
The Credit Doesn't Transfer To The Buyer
The owner-occupancy reduction stays with the person who applied for it, not with the house. Under ORC 323.153, an approved application continues while the home stays the applicant's homestead. A homestead that changed hands in the preceding year needs a new application, filed by December 31 of the year the reduction is sought.
In Hamilton County, the first chance to apply comes at closing. Question 10 on the county's DTE Form 100 conveyance form asks whether the property will be the grantee's principal residence by January 1 of next year, and whether it's a multi-unit dwelling. Next to that question, the form warns that failing to complete the application "prohibits the owner from receiving this reduction until another proper and timely application is filed." The separate DTE 105C, "Application for Owner-Occupancy Tax Reduction," is filed with the county auditor no later than December 31.
Both forms still describe the reduction as 2.5%. The DTE 100 says "2.5% on qualified levies," and the DTE 105C carries a "Rev. 9/16" date. The filing steps on those forms still apply. The percentage on them is out of date: the current figure is 5.70% for tax year 2026, rising to 15.38%. With the credit now worth more than twice the old amount and set to grow, skipping that conveyance question costs more each year.
Living In One Unit Of A Two-Family
Cincinnati's older housing stock includes plenty of two-family homes, and the new rules have the most moving parts there. Under ORC 323.151, a homestead can be a dwelling unit within a multiple-unit dwelling, as long as the applicant owns it and lives in it. The state's DTE 105C lists "Unit within a multi-unit dwelling" as a home type. The county materials reviewed here don't say how the credit is split between an owner's unit and a rented unit in the same building. The reduction attaches to the homestead unit, and the Hamilton County Auditor's office is the place to confirm how a particular parcel is calculated.
The same owner may have two rental registrations to file. The Hamilton County Auditor's rental registration page answers this directly. An owner who lives in one unit of a multifamily building still files a Residential Rental Property Registration Form if the other units are rented. The state registration is free. A property identified as a rental without a form on file may get a $150 penalty on future tax bills. The DTE 100 also asks whether the property is rented to tenants and says a new owner must register within 60 days of the transfer.
Inside city limits, there's a second registry. Cincinnati has required residential rental registration since September 1, 2020. The city's rental registration FAQ says the county filing doesn't satisfy the city requirement, and the city fee is $1 per unit.
New Values Arrive In November
This fall, Hamilton County is also reassessing values. Tax year 2026 is a triennial update, a desktop statistical review of more than 350,000 parcels based on recent sales. The Auditor's office doesn't visit homes for it. As of this writing, the Auditor's triennial page says finalized value changes aren't available yet and to check back in November. The new values apply to tax year 2026, payable in 2027. No neighborhood-level figures have been published.
When the values come out, they'll arrive alongside other changes. HB 335 requires county budget commissions in update years to adjust inside millage so that revenue growth is generally held to the prior three years of inflation. The Auditor's own FAQ says a 20% value increase doesn't mean a 20% tax increase, because levies, credits, and exemptions all affect the final bill. At a county commission meeting covered by Signal Cincinnati, deputy assistant county administrator Anson Turley explained that the reforms don't cut property taxes. They limit how fast revenue can grow when values rise.
Owners who disagree with a new value can file a complaint with the Board of Revision between January 1 and March 31, under the window the Auditor describes as set by statute. A Board of Revision complaint challenges the value, not the tax dollars. A buyer who skipped the owner-occupancy question at closing would need to file a DTE 105C by December 31 to get the credit, whatever happens with the value.
Frequently Asked Questions
Is the Inflation Cap Credit the same thing as the owner-occupancy credit? No. The Inflation Cap Credit is a different HB 186 provision, tied to school districts on the 20-mill floor. The Auditor estimates it at $73.19 per $100,000 of applicable market value for the Cincinnati City School District, applied to second-half 2026 bills. It doesn't depend on whether the owner lives in the home.
Does the owner-occupancy reduction affect the homestead exemption? They're separate programs. The Ohio Department of Taxation's homestead FAQ describes an income test for the standard homestead exemption, with exceptions for some veteran and surviving-spouse categories and for people who received the exemption before means-testing began. The HB 186 owner-occupancy change has no income test and is based on occupancy.
If I close in December, can I still get the reduction for next year? The DTE 100 ties eligibility to the home being the buyer's principal residence by January 1 of the next year, and the DTE 105C sets a December 31 filing deadline. The Auditor's office can confirm how those dates apply to a specific closing.
