Your property value went up. Maybe a lot. A letter arrived, the number looked alarming, and now you’re trying to figure out what it actually means for your wallet.
That instinct makes sense. When Cuyahoga County mailed out reappraisal notices in the summer of 2024 showing an average home value increase of 32 percent countywide, phones at the Fiscal Office started ringing. Some homeowners in East Cleveland saw proposed values jump by as much as 67 percent. In Cleveland itself, the average increase landed at 49 percent.
The fear is understandable. But the math works differently than most people expect.
What Happened
In July 2024, Cuyahoga County Fiscal Officer Michael Chambers announced the results of the county’s sexennial reappraisal — a full, ground-up assessment of all real property mandated by Ohio state law every six years.
The numbers were significant. Residential property values rose an average of 32.22 percent across the county. Commercial values increased 8.45 percent, and industrial property came in at 8.49 percent.
Chambers was direct about one key point at the announcement: the impact of valuation does not mean the same impact in tax bills. In some cases, a homeowner’s taxes may not increase at all.
Following the 2024 reappraisal, Cuyahoga County released updated Tax Year 2025 assessed valuations on December 26, 2025. These figures now serve as the foundation for all property tax calculations made during calendar year 2026.
Why This Matters for Homeowners
Ohio property taxes are not calculated like a simple percentage of what your home is worth.
The system is more layered than that, and at the center of it is a decades-old state law called House Bill 920.
Passed in 1976 during a period of rapid inflation, HB 920 changed how taxes respond to rising values. Before that law, if your assessed property values increased by 30 percent, so did your tax bill. After HB 920, when home values in a town increased, the millage decreased to keep property taxes roughly constant.
In plain terms — the tax rate adjusts down when values go up, softening or even eliminating the impact on individual bills.
This is why Chambers’ statement carried real weight. The valuation and the tax bill are connected, but they are not the same number.
Who Is Most Affected
Not every homeowner is equally shielded by HB 920, and that distinction matters.
If a property increased by exactly the same percentage as the district as a whole, the taxes for that district will stay the same. If a property increased by less than the average, taxes will decrease. If a property increased by more than the average, taxes will increase.
There is also a critical exception built into the system. Every municipality has ten mills of unvoted inside millage assessed to the community. These mills are not subject to HB 920, and governmental subdivisions will see an increase in revenue as a result of valuation changes.
Seniors and fixed-income residents carry the heaviest exposure. They face the same valuation math but have fewer options to absorb a higher payment. The county does offer a Homestead Exemption and an Owner Occupancy Credit — both worth checking for anyone who qualifies.
The Financial Impact Explained
Here is a realistic scenario to show how the numbers work.
Consider a homeowner in a Cleveland suburb who bought their home in 2019 for $175,000. If that property was reappraised at $230,000 following the 2024 cycle — a realistic figure in many parts of the county — their assessed value jumped from $61,250 to $80,500. At a modest effective rate, that shift alone could add $300 to $500 to their annual tax obligation.
On the portion of the tax bill covered by HB 920’s rollback protections, the effective rate would decrease to compensate for the higher assessed value, potentially leaving that portion unchanged. The unprotected inside millage is where the increase lands.
This is not a dramatic number for some households. For others, it is the difference between staying current and falling behind.
As of December 2025, Cuyahoga County was owed more than $248 million in overdue property taxes — a figure that signals how financial pressure from the reappraisal cycle is already showing up in delinquency patterns.
What You Should Do Now
Start by locating your current assessed value. The Cuyahoga County Fiscal Office maintains property records through the county’s online Fiscal Hub, and the Tax Year 2025 figures released on December 26, 2025 are the numbers currently in play.
Compare that value against what you believe your home would realistically sell for today. If the assessed value looks too high based on recent comparable sales in your neighborhood, you have grounds to contest it.
The county provides a tax estimator tool on its website. Plug in your new assessed value alongside your current value and it will calculate an estimated bill. That exercise takes less than five minutes and gives you a concrete number to work with.
When filing a complaint, owners should provide supporting documentation including a complete appraisal report from within the last 36 months, photographs of existing structural damage or deferred maintenance, certified repair estimates, a purchase agreement with closing statement, and sales comparisons.
Homeowners who contested their 2024 valuations and received adjustments should verify that those adjustments are accurately reflected in the December 2025 figures. If discrepancies exist, that is grounds for a new complaint.
Important Dates and Deadlines
The formal complaint window with the Cuyahoga County Board of Revision opened January 1, 2026 and closes March 31, 2026. No extensions have been announced. Missing the March 31 deadline means waiting until the next complaint cycle to contest your valuation.
Complaints can be filed online through the Board of Revision portal, by mail, or in person at the Cuyahoga County Administrative Building, 2079 E. 9th Street, 2nd Floor, Cleveland, Ohio 44115.
Online filing does not require notarization. Mail and in-person submissions do.
One caution worth noting: unlike the informal process, the formal review could potentially result in your property value being increased. Going in with solid documentation reduces that risk considerably.
Official Context and Background
The 2024 reappraisal was the most significant valuation event in Cuyahoga County in six years. It was also the first full sexennial cycle since the county’s 2018 reappraisal, with a triennial update in 2021.
The County Auditor conducts the appraisals acting as an agent of the State of Ohio Department of Taxation. The Department of Taxation issues an order to initiate reappraisals along with a deadline for completion, to which the Auditor must submit a detailed plan for state approval before commencing the reappraisal.
The 2024 reappraisal will establish tax liabilities through 2030, meaning errors in this cycle can have long-lasting financial effects. Getting the number right now carries a multi-year window of financial consequence.
The HB 920 reduction factor, mandated by Ohio law, is designed to keep tax revenues stable when property values increase or decrease, keeping revenue to schools, cities, libraries, and other local services at nearly the same level as originally approved by voters.
Key Takeaways
A 32 percent increase in home value does not produce a 32 percent increase in property taxes. Ohio’s House Bill 920 rolls back effective millage rates on voter-approved levies when values rise, cushioning the impact for most homeowners.
Inside millage — up to ten unvoted mills authorized by the Ohio Constitution — is not subject to HB 920 and will increase alongside higher assessed values.
Homeowners whose properties rose faster than their district’s average will see higher tax bills on the HB 920-protected portion as well.
The Cuyahoga County Fiscal Office released Tax Year 2025 assessed valuations on December 26, 2025. The window to formally contest those valuations closes March 31, 2026.
Homestead Exemption and Owner Occupancy Credit programs are available for qualifying residents and can reduce the net tax burden.
Frequently Asked Questions
Does a higher property valuation always mean my taxes go up?
No. Ohio’s House Bill 920 adjusts the effective millage rates on voter-approved levies downward when property values increase, which can keep taxes flat or even reduce them for homeowners whose values rose at or below the district average. However, the unvoted inside millage portion of the bill is not protected by HB 920 and will increase proportionally with higher assessed values.
What is the assessed value, and is it the same as market value?
No. Ohio law sets the assessed value at 35 percent of the property’s market value. A home valued at $200,000 carries an assessed value of $70,000. Property taxes are calculated on the assessed value, not the full market figure.
How do I know if my valuation is accurate?
Review the Tax Year 2025 figures through the Cuyahoga County Fiscal Hub online. Compare the county’s number to recent sale prices of similar homes in your neighborhood. If there is a meaningful gap, that discrepancy may be worth pursuing before the March 31, 2026 deadline.
Can the Board of Revision raise my valuation if I file a complaint?
Yes. Unlike the informal review process, a formal complaint is a full hearing. The outcome can go in either direction. Bringing strong comparable sales data or a recent appraisal is the most effective way to support a reduction request.
Where do I file a formal complaint?
Through the Board of Revision online portal, which does not require notarization, or in person and by mail at the Cuyahoga County Administrative Building, 2079 E. 9th Street, 2nd Floor, Cleveland, Ohio 44115. The Board of Revision email address is BORinfo@cuyahogacounty.us. The deadline is March 31, 2026.
Who do I contact with questions about my valuation?
