Valuation limits
Utah has no county-specific annual valuation cap comparable to Texas's homestead cap. County assessors annually update fair-market value; a qualifying primary residence and up to one acre receive a 45% residential exemption and are taxed on 55% of market value. Qualifying agricultural land may instead be valued by productive capability under the Utah Farmland Assessment Act. Official guidance: https://tax.utah.gov/propertytax/tax-relief/primary-residential-exemption/ Duchesne County also describes productive-capability valuation for qualifying agricultural land under the Greenbelt/FAA program.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
