The Eden Valley Community Center sits at 4039 US Highway 191 in Farson. On July 2, the Eden Valley Rural Healthcare District held its budget hearing there, and the budget it adopted shows the district's federal grant income falling to zero. That is why Farson-area voters will see a two-mill question on their November 3 ballot. Seven days later, on November 10, the first half of the 2026 Sweetwater County property tax bill comes due.
The bill in your mailbox now was set in September, after final mill levies were confirmed. Nothing on the November ballot changes it. The choices that will shape a Farson owner's 2027 bill are happening this fall instead: one local levy question, one statewide initiative, and an exemption affidavit that many owners can file right now.
The bill due November 10 is already settled
Sweetwater County's assessor explains that actual tax bills go out in September. That happens after the county commissioners, school boards, towns and special districts hold their budget hearings and the commissioners confirm final mill levies. According to the Sweetwater County Treasurer, owners can pay the full amount by December 31 or split it into two installments, with the first half due November 10 and the second half May 10.
So the 2026 bill is fixed. The estimate printed on your April notice of value used the previous year's mill levy for your tax district. The September bill uses the levy that was actually confirmed. A vote on November 3 can only affect levies for future years.
How a Farson bill is built
The Sweetwater County Assessor publishes the formula in plain terms. Appraised value times the assessment rate gives assessed value. Assessed value times the mill levy gives the tax. Residential property is assessed at 9.5 percent, and one mill means $1 of tax for every $1,000 of assessed value.
The assessor puts the average levy in Sweetwater County at 71 mills, about $7.10 per $1,000 of market value. That is a countywide average. Each tax district has its own total, and a Farson-area bill includes levies that a Rock Springs or Green River bill doesn't.
Acreage buyers should know one more piece. Wyoming values property at fair market value with one exception: agricultural land is valued on what it can produce. On a parcel that combines a home with agricultural ground, the house and the land can be valued on two different bases.
Where the 25 percent exemption fits, and what it covers
Since 2025, Wyoming has exempted 25 percent of the fair market value of a single-family residential structure and its "associated improved land," on the first $1 million of value. The law that created it is Senate File 69, which has no sunset date. It applies to houses, modular homes, mobile homes, townhouses and condominiums. That matters in an area with a lot of manufactured housing.
The words "associated improved land" deserve attention on a Farson parcel. The state's homeowner exemption portal says owners can claim the exemption on the residential land where the dwelling sits if the same person owns both. It also says that land carried on a separate account needs its own application. When a home and its acreage show up as more than one account, one affidavit may not cover all of them.
Here is the county's own formula applied with the exemption, at two example values. These are illustrations, not quotes for any specific property.
| Example market value | Value after 25% exemption | Assessed at 9.5% | Tax at the 71-mill county average | Tax from 2 additional mills |
|---|---|---|---|---|
| $200,000 | $150,000 | $14,250 | $1,011.75 | $28.50 |
| $400,000 | $300,000 | $28,500 | $2,023.50 | $57.00 |
The last column is the size of the Eden Valley question. On a typical home it comes to tens of dollars a year. For the district, it is the difference between a budget that works and one that doesn't.
What the Eden Valley Rural Healthcare District runs on
The district's adopted budget for July 1, 2026 through June 30, 2027 says it will keep supporting Eden Valley Telehealth, plus the community fitness room if needed. It will also keep funding individual and community health needs through what it calls Targeted Needs funds. Eden Valley Telehealth Services was reported by SweetwaterNOW in 2016 as doing business as Big Sandy Clinic in Farson.
Three lines in that budget show where the money comes from and where it goes.
- Federal grants passed through state agencies: $66,986 actual in fiscal 2024–25, $16,860 estimated for 2025–26, and $0 budgeted for 2026–27.
- Tax levy from the county treasurer: $78,129 in 2024–25, $65,445 estimated for 2025–26, and $138,600 requested for 2026–27.
- Spending planned for 2026–27: $164,750 in total. That includes $70,000 for clinic operations, $30,000 for EMS and ambulance, and $15,000 for Targeted Needs, with $20,000 drawn from reserves.
In its budget message, the district says it is pursuing the additional two mills it can levy with voter approval "to assist in closing the gap in decreased funding over the last few years."
According to the county's 2026 general election proclamation, the ballot asks whether the district may levy two additional mills on top of its current two, with an annual cap of four. The money would go to healthcare, health promotion and related services and equipment for residents, businesses and industries in the district. Only property inside the district would carry the levy. The same ballot asks every Sweetwater County voter about a conservation district levy of up to one-quarter mill countywide. If approved, that question would return every four years until voters turn it down.
For anyone comparing Farson with Rock Springs or Green River, this is part of what a Farson tax bill pays for. A small special district funds a local clinic, ambulance support and a fitness room, and those services don't show up anywhere on a listing sheet.
The statewide question starts with 2027
Proposed Initiative Proposition Number One, the statewide measure, would exempt 50 percent of the assessed value of a qualified homeowner's primary residence. To qualify, an owner would need at least one year of Wyoming residency and six months of occupancy in the previous tax year. The first claim would be due to the county assessor by the fourth Monday in May, with annual confirmation after that.
The Secretary of State's ballot proposition summary says that if the measure passes in 2026, the earliest tax year it could apply to is 2027. The state's estimated revenue decrease is $92,614,266 in fiscal 2028 and $95,855,766 in fiscal 2029. That estimate covers state revenue only and does not include effects on local governments. A legislative staff memo notes that anyone receiving the long-term homeowner exemption could not also receive the initiative's exemption if it is enacted.
Both ballot questions, local and statewide, would first show up on bills mailed in September 2027.
The paperwork that's open now
The state portal accepts the Wyoming Residential Owner-Occupied Affidavit from October 1 through March 1. The county assessor reviews each claim. That window has been open since the start of October, and it closes nearly three months before the fourth-Monday-in-May claim date the statewide initiative would set.
There is also an occupancy requirement, and the published sources describe its timing differently. The text of Senate File 69 says that beginning with tax year 2026, the person claiming the exemption must actually live in the home at least eight months of the year. Active-duty military families are covered by an exception. The state portal presents the eight-month rule as applying to tax year 2027. It adds that if a home is purchased after January 1, 2027, the buyer's residency at a previous qualifying property may be considered. The portal sends owners to their county assessor with eligibility questions. In Sweetwater County, the Assessor's Office number is (307) 872-3700.
Long-time owners have a separate route. House Bill 45, passed in 2026, covers a primary residence when the owner or the owner's spouse is 65 or older, and when the owner or the owner's spouse has paid Wyoming residential property tax for at least 25 years. It provides a 50 percent exemption on the first $3 million of fair market value, moves the application deadline to March 1, and repeals the old sunset. It took effect July 1, 2026. The state portal says this exemption covers the primary residence and associated improved land up to 35 acres. Senate File 69 does not let an owner receive both exemptions on the same property in the same tax year.
This post is general information, not legal, tax or financial advice. Exemptions depend on your own ownership, occupancy and parcel setup, so please confirm your situation with the Sweetwater County Assessor's Office or a tax professional.
Quick answers
Will the November 3 vote change the bill I pay on November 10? No. The 2026 bill was calculated from levies confirmed before it was mailed in September, and the statewide initiative's earliest tax year is 2027.
Does every Sweetwater County owner vote on the Eden Valley levy? The question is listed on the county's general election proclamation, and the levy would apply only to taxable property within the Eden Valley Rural Healthcare District. The proclamation does not describe the district's boundaries, so ask the County Clerk's office whether your parcel is inside it.
I own a house and the acreage around it on separate accounts. Is one affidavit enough? According to the state portal, land carried on a separate account needs its own application.
When you're looking at a Farson home or acreage, I'm happy to go through how the tax accounts are set up, which exemptions the current owner has claimed, and which local districts the parcel sits in, so the carrying cost is clear before you write an offer. At Forever West Land & Home, that kind of detail is part of every Eden Valley conversation. Let's Connect.
