How the 2026 Triennial Update Shifts the Local Property Landscape
Under Ohio law, counties must perform a sexennial reappraisal every six years and a triennial update at the three-year midpoint. Because Franklin County's last full reappraisal occurred in 2023, 2026 marks the crucial triennial update year. Led by Auditor Michael Stinziano, the office analyzes localized home sales data from the past three years to equalize property values with actual market conditions.
These adjusted values directly influence the property taxes collected for school districts, libraries, and emergency services. With the Columbus housing market maintaining steady demand, many property owners will see shifts in their assessed valuations. The Auditor's office emphasizes that an increase in property value does not equate to an equal percentage increase in property taxes, thanks to protective state measures like Ohio's House Bill 920, which dampens the impact of inflation on voted levies.
Step-by-Step Guide to Reviewing Your Value and Seeking Relief
Property owners can actively participate in the valuation process to ensure accuracy and fairness. The Franklin County Auditor provides the digital infrastructure to check tentative values and request adjustments before figures are finalized for the upcoming tax year.
To secure your property’s financial accuracy, utilize the following resources:
- Verify Tentative Values: Use the online Real Estate Search tool on the Auditor's official portal to view the newly proposed 2026 triennial valuation.
- Schedule an Informal Review: If the proposed value does not reflect the current market or your home has structural damage, schedule an informal consultation online before the September 11, 2026 deadline.
- Apply for Tax Reductions: Eligible seniors, disabled veterans, and surviving spouses should submit their Homestead Exemption applications before the end of the calendar year to lock in lower taxable values.
- Confirm the Owner-Occupancy Credit: Ensure your primary residence is registered for the 2.5% tax reduction if you purchased a home recently.
