How Property Tax Works

Kane County, Utah operates under a property tax system that generates revenue to fund essential county services, schools, and various special districts. Property taxes are the primary funding source for local government operations, including law enforcement, road maintenance, emergency services, and public education. The county assesses, bills, collects, and distributes property taxes for all taxing entities within its boundaries.

The effective property tax rate in Kane County varies significantly by location due to the presence of multiple special taxing districts, including school districts, fire districts, water districts, and other municipal services. For 2025, Kane County's base tax rate is 0.2006% (0.002006), but when combined with school districts and other special assessments, total rates typically range from 0.8% to 1.4% depending on your specific location within the county. Property owners should note that their actual tax rate depends on which special taxing districts serve their property, making each tax bill unique to its geographic location.

Supplemental Tax Bills

Supplemental taxes in Kane County are additional property tax assessments that occur when there are changes in property ownership, new construction, or improvements that increase a property's assessed value mid-tax year. These supplemental assessments ensure that property taxes are properly allocated based on current ownership and property values throughout the tax year.

Common triggers for supplemental taxes include: purchasing a home, completing new construction, adding significant improvements like pools or additions, or subdividing property. The supplemental tax is calculated by determining the difference between the old and new assessed values, then applying the current tax rate to that difference for the remaining portion of the tax year. For example, if you purchase a $500,000 home in January that was previously assessed at $300,000, you would receive a supplemental tax bill for the $200,000 difference prorated for the remaining months of the tax year.

Escrow & Property Taxes

Most mortgage lenders in Kane County require property tax escrow accounts, where monthly tax payments are collected along with your mortgage payment and held until tax bills are due. Lenders typically collect 1/12th of your estimated annual property tax bill each month, plus an additional cushion amount to ensure adequate funds are available when taxes become due.

Property tax payments from escrow accounts are typically made by your lender on or before the September 15 deadline. It's important to verify that your lender has received your tax bill and made payment on time, as you remain ultimately responsible for ensuring taxes are paid even when using an escrow account. You can monitor your escrow account through your mortgage servicer's online portal and should receive an annual escrow analysis showing projected tax amounts for the upcoming year. If your property taxes increase significantly due to reassessment or new special district taxes, your monthly escrow payment may be adjusted accordingly.
