Ohio property taxes are local taxes on real estate that fund schools, police and fire departments, roads, libraries, and municipal services.
They are calculated based on the assessed value of your property—which is 35% of its market value—multiplied by the local millage rate, with credits and exemptions applied to reduce your final bill.
This guide explains everything Ohio homeowners, buyers, and investors need to know about property tax calculations, county rates, available exemptions, payment deadlines, and the appeal process.
What Are Ohio Property Taxes?
Property taxes in Ohio are ad valorem taxes—meaning they are based on the value of your property. These taxes are levied by local governments, not the state of Ohio, and the revenue stays within your community to fund essential public services.
What Do Ohio Property Taxes Fund?
Your property tax dollars support:
- Public schools — the largest share of most tax bills
- County and municipal governments
- Police and fire departments
- Libraries and park districts
- Infrastructure — roads, bridges, and utilities
- Special districts — sanitary, water, and other services
Because each community has different needs and voter-approved levies, property tax rates vary significantly across Ohio’s 88 counties.
Who Administers Ohio Property Taxes?
Three government entities play key roles in the property tax system:
| Role | Responsibility |
|---|---|
| County Auditor | Assesses property values, determines the assessed value of every parcel, and serves as secretary of the Board of Revision |
| County Treasurer | Collects property tax payments and manages delinquent tax collections |
| Ohio Department of Taxation | Provides statewide oversight, guidance, and distributes rollback reimbursements to counties |
Who Pays Ohio Property Taxes?
All real property owners in Ohio pay property taxes, including:
- Homeowners — both owner-occupied and rental properties
- Commercial and industrial property owners
- Owners of agricultural land
- Owners of manufactured homes
If you rent, you do not pay property taxes directly, but landlords typically pass these costs through in your rent.
Important: Property taxes are a lien on the property. If you own real property in Ohio, you are responsible for the taxes regardless of whether you receive a bill in the mail.
How Ohio Property Taxes Are Calculated
Ohio’s property tax calculation follows a straightforward formula, but it involves several important terms that are often misunderstood. Understanding each step helps you verify your tax bill for accuracy.
Market Value vs. Assessed Value
Market value is the amount a willing buyer and willing seller would agree to in an arm’s-length transaction. Your county auditor determines market value based on comparable sales, property characteristics, and market conditions.
Assessed value—also called taxable value—is what your taxes are actually calculated on. In Ohio, assessed value is 35% of market value, as set by the Ohio Constitution and Ohio Revised Code (ORC) § 5713.01.
Example: If your home has a market value of $200,000, your assessed value is $200,000 × 35% = $70,000.
What Is a Mill?
Property tax rates in Ohio are measured in mills.
- One mill = $1 of tax for every $1,000 of assessed value
- One mill = one-thousandth of a dollar ($0.001)
- Ten mills = one penny
Example: With an assessed value of $70,000, a tax rate of 50 mills produces $70,000 × (50 ÷ 1,000) = $3,500.
Inside Mills vs. Outside Mills
Inside mills are the constitutional base rate of 10 mills that all Ohio property owners pay. This base rate provides all governmental units with a base amount of operating revenue.
Outside mills are voter-approved levies that exceed the 10-mill base. These include:
- School district operating levies
- Township and municipal levies
- Library and park district levies
- Special assessment districts
When voters approve new levies, your outside millage—and your tax bill—increases.
CPA Tip: Many homeowners mistakenly believe they are taxed on their home’s full market value. In reality, you are taxed on only 35% of that value—a significant protection built into Ohio law.
Ohio Property Tax Rates by County
Ohio’s property tax rates vary widely by county, reflecting differences in local government spending, school funding needs, and voter-approved levies.
Statewide Overview
According to the Tax Foundation, Ohio has an effective property tax rate of approximately 1.36% on owner-occupied housing value. The effective rate is your actual tax bill divided by your home’s market value—a more useful comparison than nominal millage rates.
Counties with the Lowest and Highest Rates
While official rates for all 88 counties must be verified through the Ohio Department of Taxation, the following general patterns are observed:
- Higher rates tend to occur in counties with significant urban areas, higher property values, and more voter-approved levies
- Lower rates often appear in rural counties with fewer services and lower property values
Complete County Rate Data
For the most accurate and up-to-date property tax rate information for your specific county, use the Ohio Department of Taxation’s The Finder tool or contact your county auditor’s office directly.
CPA Tip: The effective tax rate (tax bill ÷ home value) is more useful than the nominal millage rate for comparing counties, because it reflects your actual tax burden after all credits.
Ohio Property Tax Exemptions and Credits
Ohio offers several property tax exemptions and credits that can significantly reduce your tax bill. If you are not claiming every credit you qualify for, you are overpaying.
Homestead Exemption
The Homestead Exemption reduces your property taxes by shielding a portion of your home’s value from taxation.
Standard Homestead Exemption:
- Value shielded: $29,000 of appraised value
- Eligibility: Homeowners age 65+ or permanently and totally disabled
- Income limit: $41,000 household income for 2026 applicants (based on 2025 income)
- Income definition: Ohio Adjusted Gross Income (OAGI) + spouse’s income
- Income exclusion: Social Security benefits are not counted
- Age requirement: Must be 65 by December 31 of the application year
Application: File DTE Form 105A with your county auditor by December 31 of the application year.
Enhanced Homestead Exemption (Disabled Veterans):
- Value shielded: $58,000 of appraised value
- Eligibility: 100% service-connected disability rating, honorable discharge
- Income limit: None
- Application: File DTE Form 105I with your county auditor, and provide VA determination letter and DD214
Note for surviving spouses: A surviving spouse may continue receiving the benefit until remarrying.
Owner-Occupancy Credit (2.5% Rollback)
The Owner-Occupancy Credit (also called the 2.5% rollback) reduces taxes for owner-occupied primary residences. This credit currently equals 2.5% of your tax before credits.
The credit applies automatically to your primary residence. No separate application is required, but verify it appears on your tax bill.
10% Nonbusiness Rollback (Being Phased Out)
The 10% Nonbusiness Rollback has historically applied to residential and agricultural property. Under House Bill 186, this credit is being phased out over four years:
| Tax Year | 10% Rollback Rate |
|---|---|
| 2026 | 7.5% |
| 2027 | 5.0% |
| 2028 | 2.5% |
| 2029+ | 0% (eliminated) |
Important: Agricultural land retains the full 10% rollback.
CAUV (Current Agricultural Use Value)
The CAUV program allows agricultural land to be valued based on its income-producing ability rather than its market value.
- Minimum requirement: 10+ acres
- Use requirement: Exclusively devoted to commercial agriculture for 3+ years
- Application: File with your county auditor
House Bill 186: Owner-Occupancy Credit Expansion
HB 186 also increases the Owner-Occupancy Credit from 2.5% to 15.38% by 2029:
| Tax Year | Owner-Occupancy Credit |
|---|---|
| 2026 | ~5.70% |
| 2027 | ~8.92% |
| 2028 | ~12.15% |
| 2029+ | 15.38% |
Combined effect for owner-occupied non-agricultural property:
| Tax Year | Combined Credit |
|---|---|
| 2026 | ~13.2% |
| 2027 | ~13.92% |
| 2028 | ~14.65% |
| 2029+ | 15.38% |

| County | First Half Due | Second Half Due |
|---|---|---|
| Auglaize | February 17, 2026 | July 15, 2026 |
| Belmont | February 20, 2026 | July 24, 2026 |
| Cuyahoga | (bill mailed July 13) | August 13, 2026 |
| Wayne | February 26, 2026 | July 30, 2026 |
Important: Due dates vary by county. Always verify with your county treasurer. Missing the deadline triggers penalties and interest.
How to Pay
You can pay your Ohio property taxes through:
- Online: Most county treasurer websites accept online payments
- Mail: Send payment to your county treasurer
- In person: Visit your county treasurer’s office
- Escrow: Many mortgage companies collect property taxes through your monthly mortgage payment
Tip: Most counties offer online payment through their treasurer’s website. Set up reminders to avoid missing the deadline.
What Happens If You Don’t Pay?
Failure to pay property taxes results in:
- Penalties and interest — 7% interest for 2026
- Tax lien — The county places a lien on your property
- Foreclosure — If taxes remain unpaid, the property is subject to foreclosure
Warning: Contact your county treasurer immediately if you cannot pay. Payment plans may be available.
How to Appeal Your Ohio Property Taxes
If you believe your property is over-assessed, you have the right to appeal.
When to Consider an Appeal
Signs that you may be over-assessed:
- Your assessment is significantly higher than recent comparable sales
- Your property has physical issues (damage, deferred maintenance) not reflected in the value
- Your assessment increased substantially while neighboring properties did not
CPA Tip: Check your assessment annually. Even if your tax bill hasn’t changed much, your property may be over-assessed relative to market value. An appeal can save you thousands over time.
The Appeal Process — Step by Step
Step 1: Informal Review
Contact your county auditor’s office to discuss your assessment. Many issues are resolved at this stage without formal filing.
Step 2: Formal Complaint — Board of Revision
- File DTE Form 1 (Complaint Against Valuation) with the Board of Revision
- Deadline: March 31 at 4:00 PM
- Filing methods:
- In person: Must be received by March 31 at 4:00 PM
- By mail: Must be postmarked by March 31
- One complaint per parcel per triennial period (unless sold or casualty)
Step 3: Board of Revision Hearing
- Hearings typically occur May through September
- The Board consists of the County Auditor (Secretary), County Treasurer, and President of the County Commissioners
- The Board must decide within 90 days of filing
Step 4: Further Appeal
- If the Board denies your complaint, you have 30 days to appeal to the Ohio Board of Tax Appeals
- You may also appeal to the Court of Common Pleas
What Evidence Do You Need?
For a successful appeal, gather:
- Recent comparable sales (3–5 sales of similar homes in your neighborhood, ideally within 6–12 months)
- Independent appraisal (if available)
- Photographs showing property condition issues
- Contractor estimates for needed repairs
Example: If you appeal, bring 3–5 recent sales of comparable homes in your neighborhood, preferably within the last 6–12 months. Photos showing property condition issues are also helpful.
Common Appeal Mistakes
| Mistake | Why It Matters |
|---|---|
| Missing the March 31 deadline | You must wait until the following year to appeal |
| Insufficient evidence | The Board needs concrete data to reduce your assessment |
| Not attending the hearing | Your absence weakens your case |
| Not filing within 30 days of Board decision | You lose your right to further appeal |
Warning: The most common appeal mistake is missing the March 31 deadline. If you miss it, you must wait until the following year to appeal.
Ohio Property Tax Legislative Updates
Several new laws took effect in 2025–2026 that significantly affect Ohio property taxes.
House Bill 186 — Inflation Cap Credit
HB 186 establishes an Inflation Cap Credit that limits how much school district property taxes can increase due to rising property values.
Key provisions:
- Caps growth in school district property tax revenue (related to the 20-mill floor) at the rate of inflation
- Retroactively applies to tax year 2025 for real property
- Appears on second-half 2026 tax bills
- Saves Ohio property owners $1.7 billion over three years
Projected savings:
| Tax Year | Projected Savings |
|---|---|
| 2025 | $432 million |
| 2026 | $608 million |
| 2027 | $633 million |
Source: Legislative Service Commission Fiscal Note
Summary of Key Changes (2026–2029)
| Change | 2026 | 2027 | 2028 | 2029+ |
|---|---|---|---|---|
| 10% Nonbusiness Rollback | 7.5% | 5.0% | 2.5% | 0% |
| Owner-Occupancy Credit | ~5.70% | ~8.92% | ~12.15% | 15.38% |
| Combined Credit | ~13.2% | ~13.92% | ~14.65% | 15.38% |
| Inflation Cap Credit | Active | Active | Active | Active |
Key Takeaway: HB 186 caps school district tax increases at the inflation rate, saving Ohio property owners nearly $1.7 billion over three years. However, the 10% nonbusiness rollback is being eliminated for most homeowners, so the effective benefit depends on your property type and county.
