July 2026 Property Tax Update: New Credits, Extended Due Dates & What It Means for Ohio Homeowners
If you’ve been waiting for your second-half property tax bill this summer, you’re not alone.
Several Ohio counties have delayed mailing tax bills and extended payment deadlines while implementing Ohio House Bill 186, legislation signed by Governor Mike DeWine that created the new Inflation Cap Credit. The law required county auditors and treasurers across the state to update tax software, recalculate qualifying property tax bills, and issue revised tax statements before bills could be mailed.
For homeowners, realtors, buyers, and sellers, here’s what you need to know.
Why Are Property Tax Bills Delayed?
Normally, second-half real estate tax bills are issued in late June or early July. This year, implementation of House Bill 186 required counties throughout Ohio to modify tax calculation systems before certifying tax bills.
Because the new credit applies to qualifying school operating levies for Tax Year 2025, every affected county had to complete extensive recalculations before tax bills could be finalized.
The result has been delayed billing schedules and extended payment deadlines in several counties.

Late Payment Penalties
Most Ohio counties apply the following statutory penalties for late payment of real estate taxes:
- 5% penalty if payment is received within the first 10 days after the due date.
- 10% penalty if payment is received more than 10 days after the due date.
Exceptions: The following counties assess a 10% late penalty immediately after the due date, without the initial 5% grace period:
- Darke County
- Montgomery County
- Preble County
Note: Due dates and penalty policies are current as of publication but may change. Property owners should always verify payment deadlines and late-payment policies with their county treasurer before remitting payment.
What Is the Inflation Cap Credit?
House Bill 186 established the Inflation Cap Credit, sometimes referred to as the 20-Mill Floor Credit, to provide targeted property tax relief in qualifying Ohio school districts following recent increases in property values.
The amount of any credit depends on several factors, including the property’s taxable value, school district, and applicable operating levies. As a result, some homeowners may see a noticeable reduction on their tax bill, while others may receive a smaller credit—or none at all.
Why School District Matters
One of the biggest questions homeowners have is why neighbors living only a few miles apart may receive very different tax credits.
The answer lies in each school district’s levy structure.
Districts that were already at or near Ohio’s statutory 20-mill floor generally will experience little or no change under House Bill 186. Other districts may qualify for larger credits depending on their existing operating levies and recent increases in property values.
Montgomery County: Why the Delay Was More Significant
Montgomery County experienced additional complexity because multiple school districts are affected by the new calculations, including districts that participate in the Montgomery County Career Technology Center (CTC) tax structure.
School districts associated with the Montgomery County CTC include:
- Huber Heights
- Brookville
- Northmont
- Jefferson Township
- Northridge
- Trotwood-Madison
- Vandalia-Butler
Additional Montgomery County school districts affected by the new calculations include:
- Miamisburg
- Valley View
- New Lebanon
- Centerville
- Kettering
- Dayton
- Oakwood
- Mad River
Because each district has different levy structures, tax calculations had to be updated individually before Montgomery County could certify and issue second-half tax bills.
What This Means During Your Closing
Fortunately, these changes should have little impact on most real estate transactions.
Title companies routinely prorate property taxes between buyers and sellers using the best certified tax information available at the time of closing. When updated tax bills have not yet been issued, Ohio’s established closing procedures allow transactions to proceed while ensuring taxes are prorated fairly.
If revised tax information becomes available before closing, settlement figures can be adjusted accordingly.
What Homeowners Should Do
If your mortgage company escrows your property taxes, you generally do not need to take any action. Your lender will receive the tax bill and submit payment by the applicable due date.
If you pay property taxes directly:
- Watch for your official tax bill.
- Review your bill for any Inflation Cap Credit that may apply.
- Pay by your county’s revised due date to avoid penalties.
