How Property Tax Works

Washington County operates under Utah's property tax system, which funds essential local services including schools, public safety, infrastructure, and county operations. Property taxes are calculated based on assessed values and applied tax rates that vary by location within the county due to different combinations of special taxing districts. For the 2025-26 tax year, Washington County has implemented a 3% increase in assessed values, generating approximately $1.742 billion in total tax revenue.

Property tax rates in Washington County typically range around Utah's base rate of approximately 1% of assessed value, though actual rates vary significantly depending on your specific location within the county. Your property may be subject to additional assessments from school districts, municipal services, special improvement districts, and other local taxing entities. The county has reduced its tax rate by $1.37 per $1,000 of assessed value in recent years, demonstrating efforts to control the tax burden while maintaining essential services.

When Are Property Taxes Due?

For the 2025/2026 tax year in Washington 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 Washington County are triggered by changes in property ownership, new construction, or significant improvements that increase a property's assessed value during the tax year. When these changes occur, a supplemental tax bill is issued to cover the difference between the original assessment and the new higher assessment for the remaining portion of the tax year.

For example, if you purchase a newly constructed home in March that wasn't on the original tax roll, you would receive a supplemental tax bill covering the period from March through the end of the tax year. The supplemental tax is calculated by taking the difference between the new assessed value and any previous assessment, multiplying by the applicable tax rate, then prorating for the months remaining in the tax year.

Section 5

Escrow & Property Taxes

Most mortgage lenders in Washington County collect property taxes through monthly escrow payments as part of your mortgage payment. Lenders typically collect 1/12 of your annual property tax bill each month, plus a small cushion to ensure adequate funds. Property tax statements are mailed by October 25th each year, and lenders receive copies to verify the correct escrow amount.

Your lender will pay your property taxes directly to Washington County by the November 30th due date. If your tax bill changes significantly due to reassessment or tax rate changes, your lender may adjust your monthly escrow payment and provide an escrow analysis explaining the changes. You can verify your property tax payments and current balance by contacting your lender or checking Washington County's online payment system.
