How Property Tax Works

Fremont County, Wyoming operates under the state's property tax system to fund essential local services including schools, county operations, fire protection, and various special districts. Property taxes are the primary revenue source for these services, with the county following Wyoming's state-mandated assessment and collection procedures.

The effective property tax rate in Fremont County varies by location within the county due to different combinations of special taxing districts such as school districts, fire districts, and improvement districts. While Wyoming maintains a base assessment rate structure, the actual tax burden depends on which special districts serve your specific property location. Property owners should expect their total tax rate to reflect these combined district levies, making location within the county a significant factor in determining overall property tax liability.

Property tax bills in Fremont County are based on assessed values determined by the County Assessor's office, with taxes collected by the County Treasurer. The assessment and collection cycle follows Wyoming state law, with specific deadlines for payments, appeals, and applications for various tax relief programs.

Total effective rates typically range around Wyoming's average of approximately 1% but vary significantly based on property location and applicable special districts.

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 Fremont County are additional tax assessments that occur when there are changes to property ownership, improvements, or assessments outside the regular annual assessment cycle. These taxes are calculated based on the difference between the previous assessment and the new assessment, prorated for the portion of the tax year remaining.

Common triggers for supplemental taxes include: change of ownership that removes existing exemptions or credits, completion of new construction or major improvements, and correction of assessment errors. The supplemental tax amount is calculated by taking the difference in assessed value, multiplying by the applicable tax rate, and prorating based on the number of months remaining in the current tax year.

For example, if a property's assessed value increases by $50,000 due to completed improvements in January, and the total tax rate is 1.0%, the annual additional tax would be $500. Since this occurred at the beginning of the tax year, the property owner would owe the full $500 as a supplemental tax bill, typically due within 30 days of the bill date.

Escrow & Property Taxes

Most mortgage lenders in Fremont County require property tax escrow accounts to ensure timely payment of property taxes. Lenders collect monthly payments equal to 1/12 of the annual tax bill plus insurance premiums, holding these funds in an escrow account to pay taxes when due.

Property taxes in Fremont County are due November 10th for the first half payment, with the second half due May 10th of the following year. Lenders typically pay the first installment by the November deadline and the second installment by the May deadline. Property owners should verify that their lender is making payments on time, as the property owner remains ultimately responsible for tax payments even when escrowed.

Escrow accounts are analyzed annually, and lenders may adjust monthly payments based on changes in tax assessments or tax rates. Property owners receive annual escrow statements showing account activity and any required payment adjustments. If escrow accounts have shortages, lenders may require additional payments or spread the shortage over 12 months in addition to the new payment amount.
