How Property Tax Works

Salt Lake County's property tax system serves as a crucial funding mechanism for essential local services including public education, law enforcement, fire protection, libraries, parks, and county operations. The Salt Lake County Assessor's Office is responsible for determining the fair market value of all real and personal property within the county, ensuring assessments comply with Utah state laws and professional appraisal standards.

Property tax rates in Salt Lake County vary by location due to different combinations of taxing entities such as school districts, municipalities, special service districts, and other local government units. The effective tax rate typically ranges from approximately 0.8% to 1.2% of assessed value, with most properties falling around the 1% range. Property owners receive annual tax notices that detail the specific rate applicable to their property based on the various taxing jurisdictions in which their property is located.

Supplemental Tax Bills

Supplemental property taxes in Salt Lake County are triggered by specific events that change a property's assessed value during the tax year. The primary triggers include change of ownership (property sales), new construction completion, additions or improvements to existing structures, and changes in property use classification. When these events occur, the County Assessor establishes a new assessed value that differs from the original assessment.

Supplemental taxes are calculated based on the difference between the new assessed value and the original assessed value, multiplied by the applicable tax rate, and prorated for the remaining months in the tax year. For example, if a home sold for $500,000 in July with an original assessed value of $400,000, and the tax rate is 1.0%, the supplemental tax would be calculated as: ($500,000 - $400,000) × 0.010 × 6/12 months = $500 for the remaining six months of the tax year.

Escrow & Property Taxes

Most mortgage lenders in Salt Lake County require borrowers to maintain an escrow account for property tax payments, collecting monthly payments along with principal and interest.

Property taxes in Salt Lake County are generally due in two installments, and lenders coordinate these payments to ensure timely submission.

Property owners should verify that their lender is making correct escrow payments by monitoring their annual escrow analysis statements and checking payment records through the Salt Lake County Treasurer's website.
