About the Newcastle Property Market
Newcastle is a city located in Iron County, Utah. Every property inside the Newcastle city limits is assessed by the Iron County assessor, which applies Utah property tax rules uniformly across the county.
Because Newcastle property values are set at the county level, the same assessment rules apply to homes throughout the city. Homeowners who believe their Newcastle home is over-assessed have the right to file a appeal directly with Iron County.
Utah allows the assessor to defend or adjust the assessed value during a appeal, so Newcastle homeowners should build a strong evidence-based case before filing — which is exactly what ProtestMax generates for $45.
Newcastle Property Market Context
Newcastle sits within Utah's broader property tax landscape as a city, and local assessments reflect both state rules and county-level mass appraisal practices.
Utah market character
Utah has a 45% residential exemption (primary residences are taxed on 55% of market value), and the state has been among the fastest-appreciating in the country. Salt Lake, Utah, and Washington counties have all produced aggressive reappraisal cycles.
How Utah handles appeals
Utah homeowners appeal to the county Board of Equalization, then the Utah State Tax Commission. The state is protest-friendly and evidence-driven.
When to file in Newcastle
BOE appeals must be filed by September 15 (or 45 days after notice mailing, whichever is later). Notices mail in late July.
Common Newcastle Property Types
Newcastle homeowners typically file protests across these property categories:
Single-family homes
The most common residential type and the dominant protest category.
Condominiums

Townhouses
Attached-home neighborhoods in newer subdivisions.
Small multi-family
Duplexes and 2-4 unit buildings assessed as income property.
