Valuation limits
Ohio HB 920 reduction factors limit increases in collections from voted levies on carryover property; the 20-mill floor, inside millage, new levies, and statutory exceptions still apply. This is a tax-collection limitation, not a general parcel valuation cap; taxable value and effective rate vary by tax district.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
