Jefferson, OH – Each fall, the Ashtabula County Auditor’s Office provides property owners with an opportunity to challenge their property values through informal valuation reviews. Auditor Scott Yamamoto announced that his office will be holding informal reviews with property owners now through September 30, 2025.
Property owners have two avenues to appeal property values:
- Board of Revision (BOR): A formal process that requires applications between January 1 and March 31 each year.
- Informal reviews: A simpler, less formal process available in the fall.
“Our goal is to have the market value of a property as of January 1, 2025 for this round of informal reviews,” said Auditor Yamamoto. “Already, we have seen sales far exceed the values placed on properties during the 2023 Triennial Update. Informal reviews allow owners to provide insight that may lead to a lower value. The mass appraisal process is broad-based and doesn’t fit every property every time. With today’s market, it’s increasingly difficult to find a lower value—but we encourage residents to present evidence for review.”
Property owners who believe their valuation is inaccurate may submit documentation such as photos, evidence of condition issues, or corrections to property records. Independent third-party appraisals remain the strongest evidence in support of a value change.
Auditor Yamamoto emphasized that informal reviews will not impact current tax bills, but will apply to bills received in 2026. “This is a much simpler, easier process compared to a formal Board of Revision hearing,” Yamamoto noted.
How to Request a Review
Property owners who filed a Board of Revision complaint in 2025 (challenging January 1, 2024 values) are not eligible to file another BOR appeal until 2027. However, informal reviews can be held annually, regardless of prior Board of Revision filings.
