How Franklin County Assesses Property

35%of market value

Assessed by: Franklin County Auditor's Office

Assessment cycle: triennial

Notices typically mailed: Spring (typically by mid-May)

In Franklin County, property taxes are calculated based on assessed value, which equals 35% of your home's market value as determined by the County Auditor. For example, if your home's market value is $241,800 (the county median), your assessed value would be $84,630 (241,800 × 0.35). At Franklin County's effective tax rate of 1.67%, this would result in approximately $4,036 in annual property taxes. This assessment ratio is mandated by Ohio state law and applies uniformly across all residential properties in the county.

The Appeal Process

Appeals are heard by the Board of Revision. The Franklin County Board of Revision consists of three elected county officials (Auditor, Treasurer, and Commission President). Hearings are formal administrative proceedings where you present market evidence to justify a lower valuation. School districts in Franklin County actively monitor complaints and may file counter-complaints arguing for higher values, especially on cases involving $50,000+ changes.

1

Step 1: Request an informal Property Value Review Session with the Franklin County Auditor's Office between July and September (available during triennial update years). This informal review can resolve many valuation disputes without formal filing.

2

Step 2: Gather evidence supporting your claim that the property is overvalued. Collect recent comparable sales (within the past 12 months), photos of property condition issues, repair estimates, or obtain a professional appraisal report.

3

Step 3: File DTE Form 1 with the Franklin County Board of Revision by March 31 of the year following the tax year. Complete the form with property details, your proposed value, and attach all supporting documentation. File online at franklincountyauditor.com/bor, by mail, or in person.

4

Step 4: Attend the Board of Revision hearing. You will receive written notice of your scheduled hearing date. Present your evidence professionally in a 5-15 minute presentation. Be prepared to answer questions from board members and note that school districts may file counter-complaints in Franklin County, particularly for large-dollar cases.

5

Step 5: Receive the Board of Revision decision by mail. If approved, your property value and taxes will be reduced. If denied or you disagree with the outcome, you have 30 days from the decision notice date to appeal to the Ohio Board of Tax Appeals or Court of Common Pleas.

Required form: DTE Form 1 (Complaint Against the Valuation of Real Property)

Frequently Asked Questions

What is the deadline to appeal my property taxes in Franklin County for 2026?
The deadline to appeal your 2026 property tax valuation in Franklin County is March 31, 2027. Ohio property taxes are paid in arrears, so you appeal the year after the tax year in question. Your complaint must be filed with the Franklin County Board of Revision between January 1, 2027 and March 31, 2027 at 11:59 PM. There are no extensions to this deadline. Missing the March 31 deadline means you must wait an entire year to appeal, during which time you'll continue paying the higher tax amount.
How do I file a property tax appeal online in Franklin County?
Franklin County allows online filing through the County Auditor's website at franklincountyauditor.com/bor. You'll need to complete DTE Form 1 (Complaint Against the Valuation of Real Property) electronically and upload supporting evidence such as recent comparable sales, photos, or appraisal reports. The online portal is the fastest filing method available. You'll need your property parcel number, which you can find on your tax bill or by searching the property database at property.franklincountyauditor.com. Make sure to submit all evidence with your initial filing for the strongest case.
What is the homestead exemption worth in Franklin County?
The standard homestead exemption in Franklin County exempts $29,000 of your home's market value from taxation for 2026 (adjusted annually for inflation). For a typical Franklin County homeowner, this translates to approximately $400-$800 in annual property tax savings depending on your specific tax district and millage rate. Disabled veterans with 100% disability ratings qualify for an enhanced exemption of $58,000 of market value with no income limits. To qualify for the standard exemption, you must be 65 or older or permanently disabled, occupy the home as your primary residence, and have Ohio adjusted gross income of $41,000 or less.
What happens at a Franklin County Board of Revision hearing?
At a Franklin County Board of Revision hearing, you present evidence to three elected officials (the County Auditor, Treasurer, and Commission President) arguing that your property is overvalued. You typically have 5-15 minutes to present your case, including comparable sales data, appraisal reports, or photos documenting property issues. The board members may ask questions about your evidence and property condition. Be aware that school districts in Franklin County actively monitor appeals and may file counter-complaints arguing your value should be higher, especially on large-dollar cases exceeding $50,000 in disputed value. After the hearing, you'll receive a written decision by mail, which you can further appeal to the Ohio Board of Tax Appeals within 30 days if unsatisfied.
How much can I save by appealing my property taxes in Franklin County?
Franklin County homeowners who successfully appeal their property valuation typically achieve reductions based on the difference between the auditor's value and the actual market value. A meaningful share of informal review cases result in value adjustments. If your home is overassessed by just 10% on the county median value of $241,800, you're potentially overpaying $414 per year in property taxes at the 1.67% effective rate. Over a typical three-year assessment cycle, that's $1,242 in unnecessary taxes. Larger overassessments can result in thousands of dollars in savings, making the appeal process worthwhile for properties with significant valuation errors.
What evidence do I need for a Franklin County property tax appeal?
The strongest Franklin County property tax appeals include recent comparable sales from the past 12 months in your neighborhood showing similar homes selling for less than your assessed value. Other compelling evidence includes a professional appraisal report prepared by a licensed Ohio appraiser, photos documenting property condition issues or needed repairs, contractor estimates for necessary work, and purchase contracts if you recently bought the home. For income properties, bring income and expense statements. The Franklin County Board of Revision requires market-based evidence demonstrating your property's true value is lower than the auditor's appraisal. Personal financial hardship or tax burden complaints are not valid grounds for appeal.
Can I appeal my Franklin County property taxes if I recently bought my home?
Yes, a recent purchase is actually one of the strongest grounds for a Franklin County property tax appeal. If you purchased your home within the past year and your assessed market value exceeds your purchase price, bring your signed purchase agreement, closing statement (HUD-1), and any supporting documentation showing the sale was an arm's-length transaction. The Board of Revision generally gives significant weight to recent sales as evidence of true market value. Make sure to file your DTE Form 1 complaint by the March 31 deadline following the tax year in question, and be prepared to explain any unusual circumstances surrounding the sale.
What is Franklin County's 2026 triennial update and how does it affect my appeal?
Franklin County conducted a triennial update in 2026 as required by Ohio law, resulting in residential property values increasing by an average of 9%. This update represents the midpoint adjustment between full sexennial reappraisals. The new 2026 values affect your 2027 tax bill, not your 2026 payments. If you disagree with your new value, you should first request an informal Property Value Review Session with the Auditor's Office between July and September 2026. If that doesn't resolve your concern, you can file a formal Board of Revision complaint by March 31, 2027. The triennial update makes 2026-2027 a critical time to review your assessment and appeal if necessary.
