How Property Tax Works

Box Elder County property taxes fund essential local services including public education, county government operations, fire protection, library services, and various special districts throughout the county. The property tax system is administered by the Box Elder County Assessor's Office, which determines assessed values based on market conditions and property characteristics.

Property owners in Box Elder County can expect effective tax rates that vary by location within the county due to different combinations of special taxing districts. These districts may include school districts, fire districts, water conservancy districts, and municipal services, which means two properties of similar value in different areas of the county may have different total tax bills. The county uses a calendar year assessment cycle, with taxes becoming due in March of the following year.

Delinquent after Dec 10

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 Box Elder County are triggered when property undergoes significant changes such as new construction, major improvements, or ownership transfers that affect the assessed value during the tax year. These taxes cover the difference between what was originally assessed and the new assessed value, prorated for the remaining portion of the tax year.

For example, if you complete a $100,000 home addition in July, and your property is in an area with a 1.1% effective tax rate, you would owe approximately $550 in supplemental taxes (50% of the year remaining × $100,000 × 1.1%). Supplemental tax bills are issued separately from regular property tax bills and have their own due dates, typically 30 days from the bill date.

Example Calculation

$300,000 Property:

  • Assessed Value: $300,000
  • Effective Tax Rate: 1.0% (varies by district)
  • Annual Tax: $3,000
  • Monthly Escrow: $250

$600,000 Property:

  • Assessed Value: $600,000
  • Effective Tax Rate: 1.1% (varies by district)
  • Annual Tax: $6,600
  • Monthly Escrow: $550

$1,000,000 Property:

  • Assessed Value: $1,000,000
  • Effective Tax Rate: 1.2% (varies by district)
  • Annual Tax: $12,000
  • Monthly Escrow: $1,000

Note: These examples use estimated effective rates. Your actual rate depends on your specific location and applicable special districts. Tax credits such as veteran or disability credits would reduce the final tax amount but require separate applications through the county assessor.

Section 5

Escrow & Property Taxes

Most mortgage lenders in Box Elder County require property tax escrow accounts, collecting monthly payments equal to 1/12 of your annual tax bill plus any applicable insurance premiums. Lenders typically conduct annual escrow analyses to adjust monthly payments based on actual tax bills and any rate changes from special districts.

Property taxes become a lien on January 1st and are due by March 15th of the following year. Lenders usually pay from escrow accounts in February or early March to ensure timely payment. Property owners should verify that their lender has paid taxes correctly and on time, as ultimate responsibility remains with the property owner. You can verify payments through the Box Elder County Treasurer's online portal or by contacting their office directly.
