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.
