Ohio has an effective property tax rate of 1.36%, ranking 12th to 13th highest nationally. Ohio’s 35% assessment ratio means taxable value is just 35% of market value, but the 20-mill school floor and HB 920 dynamics mean rapid home value appreciation can still produce unvoted tax increases. On a $225,000 home, the typical Ohio homeowner pays approximately $3,060 per year (est., Tax Foundation 2026 / U.S. Census ACS 2023).
Ohio has an effective property tax rate of 1.36%, ranking 12th to 13th highest nationally and above the 0.90% U.S. average. Ohio’s system has two structural features that set it apart from most states: a mandatory 35% assessment ratio (meaning taxable value is always 35% of appraised market value) and the HB 920 Tax Reduction Factor, which automatically reduces voted levy rates when property values rise to prevent unvoted revenue increases – except on the 20-mill school floor, which school districts retain regardless of how much values rise (est., Tax Foundation 2026).
Ohio Property Tax Rates and Assessment Formula
Ohio’s property tax system uses a 35% assessment ratio mandated by Ohio Revised Code Section 5713.03. Your home’s taxable value is always 35% of its county-appraised market value. A $225,000 home has a taxable value of $78,750. Tax rates (millage) are then applied to this taxable value. A millage of 100 mills equates to $100 per $1,000 of taxable value, or effectively 3.5% of market value, but 1.36% as an effective rate on market value for the Ohio average.
The HB 920 Tax Reduction Factor (ORC 319.301) automatically adjusts the effective rates on voted levies downward each time property values rise due to reappraisal or triennial updates. This ensures that voted levies raise essentially the same total revenue as the year they were passed – rising property values do not automatically produce higher tax bills on voted levies in Ohio. The critical exception is the 20-mill school operating floor. School districts, which represent 60% to 70% of the average Ohio property tax bill, are guaranteed a minimum of 20 mills for operating expenses. Once values rise enough that HB 920 would reduce the effective rate below 20 mills, HB 920 stops applying, and further value increases create direct, unvoted property tax increases for homeowners.
Ohio statewide effective rate. On a $225,000 home, expect approximately $3,060 per year. Cuyahoga County (Cleveland) carries the highest rate at 2.13%, producing a $4,792 annual bill on the same home (est., Tax Foundation 2026 / Census ACS 2023).

Ohio Homestead Exemption and Tax Relief Programs
Ohio’s primary homeowner relief is the Homestead Exemption (ORC 323.152), available for seniors age 65 or older, permanently and totally disabled individuals, and surviving spouses age 50 or older of a previously qualifying individual. For 2025, the exemption shields $29,000 of appraised market value ($10,150 of taxable value) from property taxation, with an income limit of $41,000 Ohio Modified Adjusted Gross Income (MAGI). In 2024, the shield was $28,000 market value ($9,800 taxable value) with a $38,600 income limit. The income limits were indexed to inflation by HB 33. The filing deadline is December 31 of the applicable tax year.
Veterans with a 100% permanent and total service-connected disability rating receive a significantly enhanced Homestead Exemption with no income limit: $58,000 of market value shielded ($20,300 taxable value) for 2025, indexed from $56,000 in 2024. This means a 100% disabled veteran with a $225,000 home effectively has only $167,000 subject to the 1.36% effective rate, saving approximately $789 per year compared to a non-exempt homeowner.
Ohio also maintains two state-funded tax rollback credits for qualifying properties. The Owner-Occupancy Credit (2.5% rollback, ORC 323.152(B)) reduces the effective tax rate by 2.5% for owner-occupied primary residences on qualifying levies. The Non-Business Credit (10% rollback, ORC 319.302) reduces taxes by 10% on residential and agricultural property levies. Critically, both rollbacks apply ONLY to levies that were passed or renewed before November 2013. Any levy passed after November 2013 does not receive these state-funded credits, meaning the effective benefit of the rollbacks diminishes each decade as pre-2013 levies are replaced by newer ones.
| Program | Benefit | Who Qualifies | Filing Deadline |
|---|---|---|---|
| Homestead Exemption – Standard (2025) | $29,000 market value shielded ($10,150 taxable value) | Age 65+ or permanently/totally disabled; Ohio MAGI at or below $41,000; surviving spouses age 50+ | December 31 with county auditor |
| Homestead Exemption – Disabled Veteran (2025) | $58,000 market value shielded ($20,300 taxable value) | 100% permanent and total service-connected VA disability; NO income limit; surviving spouses eligible | December 31 with county auditor |
| Owner-Occupancy Credit (2.5% Rollback) | State pays 2.5% of annual tax on qualifying levies | Owner-occupied primary residences; applies ONLY to levies passed before November 2013 | Automatic for qualifying properties |
| Non-Business Credit (10% Rollback) | State pays 10% of annual tax on qualifying levies | Residential and agricultural properties; applies ONLY to levies passed before November 2013 | Automatic for qualifying properties |
| CAUV (Current Agricultural Use Value) | Agricultural land taxed on use value (farming capacity), not market value; typically 50-80% lower assessed value | 10+ acres in commercial agricultural use OR less than 10 acres generating $2,500+ gross farm income per year | Application with county auditor; conversion triggers 3-year recoupment |
Important note on rollbacks: HB 186 (enacted late 2024/2025) phases out the 10% Non-Business Credit while raising the Owner-Occupancy Credit to 15.38% by 2029 on qualifying pre-2013 levies. The net effect for most owner-occupants on qualifying levies will be slightly positive. However, this restructuring does not apply to post-November-2013 levies, which are the majority of newer school and municipal levies.
Ohio Property Tax Assessment System and Appraisal Cycle
Ohio county auditors conduct a full physical sexennial (6-year) reappraisal of all real property under ORC Section 5713.01. During a sexennial reappraisal, appraisers physically inspect and revalue every parcel in the county based on current market conditions. Three years after a sexennial reappraisal, a triennial statistical update occurs (ORC 5715.24), during which auditors update property values based on recent arm’s-length sales data in each neighborhood without requiring physical inspections. Both cycles can trigger significant assessed value changes, potentially affecting tax bills – particularly in rapidly appreciating markets where the 20-mill school floor interrupts HB 920 protection.
The CAUV program for agricultural land (ORC 5713.30) is one of Ohio’s most significant assessment exceptions. Rather than market value, qualifying farmland is assessed based on an annually recalculated capitalization model using crop yields, commodity prices, and non-land production costs. This typically produces assessed values that are 50% to 80% below what the land would be worth at market value, delivering substantial property tax savings for Ohio’s active farming community. If CAUV land is converted to non-agricultural use, a recoupment penalty equal to the preceding 3 years of tax savings is assessed.
Property owners who disagree with the county auditor’s appraised value can file a complaint with the county Board of Revision, typically by April 1 of the tax year. The Board of Revision must hear the complaint and has authority to raise, lower, or maintain the value. Further appeals can be taken to the Ohio Board of Tax Appeals.
| System Element | Rule | Impact on Homeowner |
|---|---|---|
| 35% Assessment Ratio (ORC 5713.03) | Taxable value is always 35% of appraised market value | A $300,000 home has a taxable value of $105,000; millage applied to $105,000 to calculate bill |
| Sexennial Reappraisal (ORC 5713.01) | Full physical inspection every 6 years by county auditor | Most significant valuation reset; can produce large single-year bill changes in appreciating markets |
| Triennial Update (ORC 5715.24) | Statistical market analysis at 3-year midpoint; no physical inspection | Adjusts values for recent neighborhood sales data; also can trigger bill changes with 20-mill floor effect |
| HB 920 Tax Reduction Factor (ORC 319.301) | Voted levy rates automatically reduced as values rise to maintain constant revenue on existing properties | Prevents most voted levy revenue from inflating with market values – EXCEPT once 20-mill school floor is reached |
| 20-Mill School Floor (ORC 319.301(E)(2)) | School district effective rate for operations cannot fall below 20 mills regardless of HB 920 | When property values rise after the floor is reached, school tax bill rises proportionally – an unvoted effective tax increase |
| CAUV (ORC 5713.30) | Agricultural land valued on income-earning capacity, not market value | Significant tax savings for active commercial farmers; conversion triggers 3-year tax recoupment penalty |
Major Tax Districts and County Variations in Ohio
Among Ohio’s 10 most populous counties, effective rates span from 1.36% in Stark County (Canton area) to 2.13% in Cuyahoga County (Cleveland). Cuyahoga’s high rate reflects both the complexity of the Cleveland-area school district levy structure and a commercial-to-residential tax base ratio that places higher proportional burdens on homeowners. Montgomery County (Dayton, 1.71%) and Lucas County (Toledo, 1.68%) also carry above-average rates driven by urban school district funding requirements.
Franklin County (Columbus, 1.49%) benefits from one of Ohio’s fastest-growing residential markets, which provides a larger and more diverse tax base than most Ohio urban counties. Butler County (Cincinnati suburbs, 1.48%) and Stark County (1.38%) demonstrate that suburban and mid-size markets can maintain relatively moderate effective rates where school levies are more conservatively structured or where commercial development subsidizes residential homeowners.

Recent Ohio Property Tax Law Changes and 2025-2026 Outlook
HB 33 (135th Ohio General Assembly) was the most significant recent Ohio property tax legislation, indexing Homestead Exemption thresholds and benefit amounts to inflation (eliminating the need for repeated legislative updates) and creating the Joint Committee on Property Tax Review and Reform. This committee spent the better part of 2024 examining Ohio’s complex property tax structure – particularly the interaction between HB 920, the 20-mill school floor, and rapidly rising residential values in the Columbus, Cleveland, and Cincinnati metro areas. The committee issued 21 formal recommendations in December 2024.
HB 186 enacted an inflation-indexed credit against unvoted revenue generated when the 20-mill floor applies to school district operating levies, providing some relief for homeowners in rapidly appreciating markets. The bill also restructures the existing rollback credits: the 10% Non-Business Credit is being phased out on qualifying pre-2013 levies, while the Owner-Occupancy Credit is being raised from 2.5% to 15.38% by 2029 on those same levies. For owner-occupants with significant pre-2013 levies in their bills, this restructuring will be a net positive. HB 124 updated reappraisal sales sampling methodology for greater accuracy, and HB 129 revised the 20-mill floor calculation to include additional local revenue streams.
Ohio homeowners near or above $10,000 in annual property taxes should note the federal SALT deduction cap of $10,000. A Cuyahoga County homeowner paying $7,000+ annually in property taxes plus Ohio’s 3.99% top income tax rate may have a combined SALT burden exceeding the federal cap, reducing the federal tax benefit of Ohio property taxes compared to pre-2018 law.
| Change | Effective Date | Key Impact | Who Benefits |
|---|---|---|---|
| HB 33 (135th GA): Homestead CPI Indexing | Tax Year 2023 onward | Homestead Exemption thresholds and amounts indexed to inflation annually; no more legislative updates needed | Seniors and disabled homeowners; prevents erosion by inflation |
| HB 33: Joint Committee on Property Tax Reform | Created 2023; recommendations Dec. 2024 | Comprehensive review of HB 920, 20-mill floor, rollback credits; 21 recommendations issued Dec 2024 | All Ohio property taxpayers (long-term structural review) |
| HB 186: 20-Mill Floor Relief Credit | Late 2024/2025 implementation | Inflation-indexed credit curbs unvoted revenue growth from 20-mill school floor during appreciation cycles | Homeowners in rapidly appreciating markets where floor is active |
| HB 186: Rollback Credit Restructuring | Phased to 2029 | 10% Non-Business Credit phased out; Owner-Occupancy Credit raised to 15.38% on pre-2013 levies | Owner-occupants with significant pre-November-2013 levies |
| HB 124 and HB 129: Assessment Methodology Updates | 2024-2025 | Updated sales sampling methodology; revised 20-mill floor calculation for greater accuracy | All property owners subject to county reappraisal |
Disclaimer and Methodology
This calculator provides estimates for planning purposes only. Ohio’s actual property tax structure is complex: your taxable value is 35% of appraised market value (not the full market value you enter), and your bill is determined by the combined millage of your specific school district, township, municipality, and county – not the county-wide average rate shown here. HB 920 reduction factors, the 20-mill school floor dynamic, and pre-2013 rollback credits all affect the real bill in ways this calculator cannot simulate. Before purchasing property, always request the actual tax bill from the county auditor’s office.
What this calculator does not account for:
- HB 920 Tax Reduction Factors on voted levies (which reduce effective rates on existing levies as values rise)
- The 2.5% Owner-Occupancy Credit and 10% Non-Business Credit on pre-November-2013 levies
- Specific school district, municipal, and township levies at your exact address (which can vary significantly within the same county)
- CAUV for agricultural land; inside millage allocations; and special assessment districts
How to get an accurate estimate:
- Look up your property parcel on your county auditor’s website (search by address or parcel number) to find the current appraised value, assessed value (35%), and itemized tax bill.
- Review the specific school district, township, and municipal millage rates listed on your county auditor’s tax rate table for your tax district.
- Apply for the Homestead Exemption at your county auditor’s office before December 31 if you are age 65+ or permanently disabled.
- If you believe your appraised value is too high, file a complaint with the county Board of Revision by April 1.
