In response to the current COVID 19 crisis, The Sweetwater County Assessor’s Office would like to take this opportunity to remind all Sweetwater County residents of the services that are available over the phone and through email. Current Sweetwater County veterans can renew their veteran’s exemption by calling our office at 307-872-3700. Businesses trying to send in personal property renditions can do that by regular mail or by email at email@example.com. Any general property questions may be answered by going to the Sweetwater County MapServer https://maps.greenwoodmap.com/sweetwater/
We would encourage all residents to call our office to confirm the “need” to come into the office in person. We are here to serve our tax payers, but if we can provide the appropriate service by phone or email, that would be better for our employees and the tax payers in general.
In addition, our field inspection teams will not be going out to inspect property until we feel there is no danger to the public or our staff.

Sweetwater County Assessor
This site has been prepared by the Sweetwater County Assessor's Office to help property owners better understand the functions of the Assessor's Office and provide information on what tax relief programs are available, how property tax is determined, how real property is assessed, what personal property a business should declare, and much more. Please check out the links on the left for more information.
The goal of the Assessor's Office is to assist the taxpayer in an efficient, knowledgeable, and friendly manner. We strive to provide accurate information and will always make the service we provide to the citizens of Sweetwater County our top priority. If you have any questions regarding the value of your property or the valuation process, the Assessor's Office is always ready to assist and serve you.
Duties & Responsibilities
It is the statutory duty of the Assessor's Office to locate, identify, and value all taxable property (real property, personal property and mobile homes) in Sweetwater County as of January 1 of each year. The assessors are mandated and prescribed by state law on how and when assessments are performed.
The assessor strives to value properties accurately, fairly, and uniformly according to guidelines from Wyoming Statutes and the Wyoming Department of Revenue. The office also maintains property information including maps, legal descriptions, owner information, and improvement details. In addition, the Assessor’s Office maintains a property file and property card on every parcel of land that is not exempt.
What We Don't Do
The assessor does not establish the dollar amount of taxes nor does the assessor bill or collect taxes. The voting taxpayers, county commissioners, state limitations, and assessed values determine the tax rate for each of the tax districts in Sweetwater County. The County Treasurer's Office is responsible for billing and collecting taxes. Building permits are issued by the Sweetwater County Planning and Zoning Office and the cities of Rock Springs and Green River.
