How Property Tax Works

Natrona County's property tax system serves as the primary funding mechanism for essential local services including public schools, fire protection, libraries, and county government operations. Property owners in Natrona County can expect effective tax rates that vary significantly based on their location within the county due to different combinations of special taxing districts such as school districts, fire districts, and municipal improvement districts.

The county follows Wyoming's standard property tax structure where properties are assessed at market value, then various tax credits may be applied to reduce the final tax bill. While Wyoming's base state rate averages around 1%, actual rates in Natrona County typically range higher due to local levies and special assessments. Property owners should note that tax rates can vary considerably even between neighboring properties depending on which special taxing districts serve their specific location.

When Are Property Taxes Due?

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

Supplemental Tax Bills

Supplemental taxes in Natrona County are triggered when there are changes in property ownership, new construction, or significant improvements that weren't reflected in the regular assessment cycle. These taxes cover the period from when the change occurred until the next regular tax bill cycle, ensuring the county collects appropriate revenue for the full tax year.

For example, if you purchase a newly constructed home in March that wasn't included in the January assessment roll, you would receive a supplemental tax bill covering March through the end of the fiscal year. The supplemental tax is calculated by taking the difference between the new assessed value and any previous assessment, applying the appropriate tax rate, and prorating it for the months remaining in the tax year.

Escrow & Property Taxes

Most mortgage lenders in Natrona County require property tax escrow accounts, where monthly payments are collected along with your mortgage payment and held until taxes are due. Lenders typically pay your property taxes directly to the county treasurer by the November 15 deadline each year. Your lender will conduct an annual escrow analysis to ensure adequate funds are being collected, which may result in payment adjustments.

Property owners with escrowed taxes should verify that payments were made correctly by checking their account status online or contacting the Natrona County Treasurer's Office. If you pay taxes directly without escrow, you're responsible for ensuring timely payment to avoid penalties and potential tax lien procedures. Payment options and account verification are available through the official county portal at https://www.natrona.net/150/Treasurer.

Frequently Asked Questions

Q: When are property taxes due in Natrona County? A: Tax notices are mailed by October 10 each year, with payment due by November 15 for the current fiscal year. Late payments incur penalties and interest charges.

Q: What tax credits are available and do they require applications? A: Wyoming offers homestead tax credits and senior citizen tax credits that reduce your tax bill (not assessed value). All credits require separate applications filed with the county assessor - they are NOT automatic.

Q: How does the homestead tax credit work? A: The homestead credit caps annual assessment increases rather than reducing market value. You must file an application with supporting documentation. This limits how much your assessed value can increase year-over-year, providing tax stability.

Q: When are properties reassessed? A: Natrona County conducts ongoing assessment updates with full market reviews typically every few years. Property owners receive assessment notices and have appeal rights during specified periods.

Q: What are the penalties for late payment? A: Late payments incur interest charges and penalties. Properties with delinquent taxes may eventually face tax lien procedures, so timely payment is essential.

Q: Can I pay property taxes online? A: Yes, online payment options are available through the Treasurer's Office website. Multiple payment methods are typically accepted including electronic transfers and credit cards (fees may apply).

Q: Why do tax rates vary within Natrona County? A: Different areas are served by different combinations of school districts, fire districts, municipalities, and special improvement districts, each with their own levy rates that combine for your total tax rate.

Q: How do I appeal my property assessment? A: Assessment appeals must be filed during specific timeframes with the county assessor's office. Contact the assessor at https://www.natrona.net/152/Assessor for current procedures and deadlines.
