This tool helps taxpayers and policymakers better understand property assessment in Utah, allowing anyone to examine property values across the State based on various metrics. By default, the tool shows the percent change in year—over-year property values on a parcel-by-parcel basis.
We believe the quality of public data improves as it is used. We also believe in transparency — connecting citizens with their data — to improve oversight, increase accountability, and ultimately provide a better understand of Utah’s real property tax system. (Real property includes land and buildings.) This tool brings together these elements.
We compiled property assessment data from county assessors and integrated it into this unified property valuation tool. The underlying data comes directly from county assessors. We added standardized property types and tax exemption classifications to improve searchability but included original parcel description information.
Explore the map by clicking and dragging your mouse cursor. To quickly find a specific parcel, simply click the Search button (the magnify glass icon in upper right corner of map), then enter the desired street address.
A huge thank you to all the county assessors who promptly shared their data, provided valuable feedback, and collaboration in developing this innovative tool.
We also express appreciation to our colleagues at the Utah Geographic Resource Center for their advice and help in developing this GIS-based tool.
The default map shows the percent change in year-over-year property values. As an example, assume a parcel was valued at $500,000 in 2022 and increased in value to $625,000 in 2023 — an increase of 25%. The tool would visually display this significant increase in value. Conversely, assume a parcel was valued at $625,000 in 2022 decreased in value to $500,000 in 2023 — a decrease of 25%. The tool would visually display this significant decreased. And the tool does this on a parcel-by-parcel basis.
2023 Tax Year Data was submitted shortly after the May 22nd tax rolls were closed. This assessment data is subject to change, such as based on a successful appeal. Data shown in this tool is a "snapshot" in time and will change as updated. Checking the "Date Data Received From County" field allows you to see the date we received the property value information. We anticipate updating this data twice each year (before and after the board of equalization process).
The "Detailed Property Review Date" is the date when an assessor last reviewed a parcel in detail. Depending on the county, this may involve an in-person visit, a remodel or other new improvement, or the use of aerial imagery to assess a parcel. Important Note: Counties treat this field differently, so comparing this field across counties is discouraged.
If you believe that there are issues with your property's characteristics, please contact your county assessor.
If you disagree with the assessed market value of your property, you may file an appeal with your county. Instructions for filing that appeal may be found on your Notice of Property Valuation and Tax Changes.
The county Board of Equalization (BOE) is a key step in the property valuation appeals process. If you disagree with the assessed market value of your property, you may file an appeal with your county. Instructions for filing that appeal may be found on your Notice of Property Valuation and Tax Changes. Applications for appeal of locally assessed real property are due to the county board of equalization Sep. 15th or 45 days after the mailing of valuation notices. Hearings are held and decisions made through October 1.
To learn more about the BOE process, please visit the Utah State Tax Commission's Property Tax Division Board of Equalization Standards of Practice.
This is the first time Utah has published an unified property valuation tool for the public. Some counties were unable to share their assessment data within a timely manner. We utilize parcel geometry from the Utah Geographic Resource Center to show parcels on this map, if the parcel id does not match between the dataset sent to us by the county assessor and the UGRC parcel geometry dataset, then the parcel will not show up on the map.
Note: Iron county has sent us assessment data, but we are processing it for the map tool.
