How Property Tax Works

Property taxes in Tooele County, Utah, fund essential local services including schools, law enforcement, fire protection, roads, and county operations. The county operates under Utah's property tax system where properties are assessed at fair market value and taxed according to rates set by various local taxing entities. Tooele County's certified tax rate for 2025 is 0.000923%, though this represents only the county's portion of your total property tax bill.

Your actual property tax rate will be significantly higher than the county rate alone, as it includes additional levies from school districts, municipalities, special service districts, and other local entities. Total effective rates in Tooele County typically range from 0.8% to 1.2% of assessed value, depending on your specific location and the combination of taxing districts that serve your property. Properties in different areas of the county may have substantially different total rates due to varying municipal services, school district bonds, fire districts, and other special assessments.

When Are Property Taxes Due?

For the 2025/2026 tax year in Tooele County, property taxes are due in two installments:

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental taxes in Tooele County are additional property taxes that may be assessed when there are changes to your property's value or ownership outside the normal assessment cycle. These supplemental assessments typically occur due to new construction, major improvements, changes in ownership that trigger reassessment, or corrections to previous assessments.

When supplemental taxes are levied, they are calculated based on the difference between the old assessed value and the new assessed value, multiplied by the applicable tax rate, and prorated for the portion of the tax year remaining. For example, if you complete a $100,000 home addition in March that increases your assessed value, you would owe supplemental taxes on that additional $100,000 of value from March through the end of the tax year. The supplemental bill would show the additional assessed value, the applicable rate, and the prorated time period for which the additional taxes are due.

Section 5

Escrow & Property Taxes

Most mortgage lenders in Tooele County require borrowers to maintain an escrow account for property taxes, especially when the loan-to-value ratio exceeds 80%. Your lender collects monthly escrow payments as part of your mortgage payment and pays your property taxes directly to the county when they become due on November 30th. Lenders typically collect slightly more than the estimated annual tax amount to ensure sufficient funds are available and to maintain a cushion for potential rate increases.

Each year, your lender will conduct an escrow analysis to compare actual tax payments with the amount collected. If your property taxes increase due to higher assessments or rate changes, your monthly escrow payment will be adjusted accordingly. You should receive an annual escrow statement showing the activity in your account. If you pay your own property taxes, ensure payments reach Tooele County by November 30th to avoid penalties that begin December 1st. You can verify your escrow payments and account for any supplemental tax bills that may not be included in your regular escrow calculation.

Frequently Asked Questions

When are property taxes due in Tooele County? Real property taxes are due by November 30th without penalty. Personal property taxes are due by May 15th. Real property taxes become delinquent and subject to penalties starting December 1st.

What tax credits are available and how do I apply? Tax credits in Tooele County may include residential exemptions for primary residences, veteran exemptions, and exemptions for disabled persons or low-income seniors. These are not automatic and require separate applications to the Tooele County Assessor's office. Contact (435) 843-3157 for specific eligibility requirements and application deadlines.

How does the homestead exemption work? Utah's residential exemption provides property tax relief for primary residences. This exemption may limit assessment increases rather than reducing market value directly. You must apply with the assessor's office and the exemption is limited to one primary residence per household on no more than one acre of land per residential unit.

When are properties assessed and how can I appeal? Properties are assessed annually as of January 1st. Assessment notices are typically mailed in the spring. If you disagree with your assessment, you can appeal to the Tooele County Board of Equalization. Appeal deadlines and procedures are included with your assessment notice.

What are the penalties for late payment? Property taxes become delinquent December 1st if not paid by November 30th. Delinquent taxes accrue interest and penalties that can eventually lead to tax sale proceedings if left unpaid for several years.

Can I pay property taxes online? Contact the Tooele County Treasurer's office at (435) 843-3148 for current online payment options and accepted payment methods. Many Utah counties offer online payment systems for property taxes.

Why did my tax bill increase when rates stayed the same? Your tax bill can increase even with stable rates due to higher assessed values from market appreciation, new construction, or the addition of special district taxes. Changes in exemptions or credits can also affect your final tax amount.

What are special district taxes? Special districts provide specific services like fire protection, water, sewer, parks, or libraries. These districts levy their own property taxes in addition to county and municipal taxes. Your total rate depends on which special districts serve your property location.
