Wyoming Property Tax: Search County Records, Pay Your Bill, Calculate Taxes & Claim Relief
Use this Wyoming property tax guide when you need to find the right county payment portal, search a parcel, understand taxable value, calculate a bill from mill levies, check due dates, apply for the 2026 owner-occupied exemption, use the property tax refund program, claim a veteran exemption, or appeal a county assessment.
What Wyoming property tax searchers usually need first
Wyoming property tax is county-administered. The state sets assessment rules and relief programs, but each county assessor handles values and records, and each county treasurer handles payment.
Fast action board
- 1Need to pay a bill? Use the county treasurer for the county where the property is located. Do not use the state DOR residential page as a payment portal.
- 2Need value or owner details? Use the county assessor. Wyoming DOR says assessors handle property value, ownership, addresses, legal descriptions, tax relief, tax rates and valuation appeals.
- 3Need parcel map context? Use the Wyoming Statewide Tax Districts & Parcel Viewer or the county GIS/map if available.
- 4Need to estimate tax? Residential taxable value is market value × 9.5%. Then multiply taxable value by the mill levy.
- 5Need 2026 owner-occupied exemption? Complete the Wyoming Residential Affidavit Claim and let your county assessor review qualification.
- 6Need refund or veteran exemption? Use Wyoming DOR tax relief rules, but file through the correct county or state route by the correct deadline.

Identify county
Use the county where the property sits, not where you live now.
Search assessor
Find market value, taxable value, ownership and legal description.
Pay treasurer
Use county treasurer for tax bill, receipt, escrow and delinquency.
Appeal or claim relief

How to look up Wyoming property tax records
Wyoming has no single statewide tax-payment portal for every county. Use the county treasurer for bill/payment lookup and the county assessor for value/property-record lookup.
1
Find the county where the property is located
This controls the assessor, treasurer, tax district and appeal route.
▾
Confirm the physical county first. Cheyenne is usually Laramie County, Casper is Natrona County, Jackson is Teton County, Gillette is Campbell County, Rock Springs is Sweetwater County, Sheridan is Sheridan County, and Lander is Fremont County.
2
Use the county assessor for value and parcel facts
Best for market value, taxable value and ownership data.
▾
Open Wyoming DOR’s County Assessor Contacts. Go to the official assessor site for your county and search by owner, address, parcel number or legal description if the county offers online search.
3
Use the county treasurer for bill and payment status
Best for amount due, receipt, escrow and delinquent status.
▾
Search your official county treasurer website for property tax payment. Verify parcel, owner, tax year, bill amount, payment history and mailing address before paying.
4
Use parcel viewer only for map context
Maps help with location and tax district, but deeds/surveys control legal issues.
▾
Use Wyoming DOR’s Maps & GIS Data page for the Statewide Tax Districts & Parcel Viewer. For legal boundaries, easements, mineral rights or title disputes, verify recorded documents and survey information.
| Need | Use This Office / Tool | What To Check |
|---|---|---|
| Pay tax bill | County Treasurer | Tax year, amount due, half/full payment, receipt and delinquency. |
| Check market value | County Assessor | Market value, taxable value, land/building details and classification. |
| Find parcel visually | Statewide Parcel Viewer or county GIS | Parcel location, tax district, nearby parcels and map context. |
| Correct mailing address | County Assessor first, then Treasurer if needed | Owner name, old address, new mailing address and parcel ID. |
| Appeal assessment | County Assessor / County Board of Equalization | Assessment notice date, market-value evidence and 30-day deadline. |
How to pay Wyoming property taxes correctly
Wyoming property taxes are paid to the county treasurer. Payment portals, card fees, receipt options and escrow handling vary by county, but the state due-date framework is consistent enough to plan around.
| Payment Issue | Wyoming Rule / Practical Detail | User Action |
|---|---|---|
| Where to pay | County Treasurer of the county where taxes are levied | Use the official county treasurer portal or office. |
| First half | 50% of taxes are due by November 10 | Pay or confirm escrow before November 10. |
| Second half | Remaining 50% due by May 10 of the succeeding calendar year | Calendar the May 10 deadline if paying in halves. |
| Full payment | County treasurer pages commonly explain full-payment options and interest handling | Read your county bill before choosing half or full payment. |
| Escrow | Mortgage companies often request tax data and pay in November/May | Verify lender payment before duplicate paying. |
1
Start from your county treasurer
Do not pay through an unofficial ad or generic tax site.
▾
Search for your county’s official treasurer property tax page. Confirm the page is on the official county domain before entering payment information.
2
Confirm the correct parcel and tax year
Wrong parcel or old-year payments create refund delays.
▾
Before paying, match owner, property address, parcel number, tax year, half-payment status, total due, interest and mailing address. For recent purchases, compare closing documents with the treasurer record.
3
Check mortgage escrow before paying
Wyoming county treasurer pages often explain mortgage company handling.
▾
If your lender escrows taxes, call the mortgage servicer or check escrow activity before paying directly. Ask whether the lender requested the county tax bill and whether payment will be sent for November and May installments.
4
Save the receipt and re-check posting
Especially important for online card/e-check and mailed payments.
▾
Save confirmation number, tax year, amount, date, parcel number and payment method. Reopen the county treasurer record later to confirm the payment posted to the right property and installment.
Wyoming property tax due dates and calendar
Use the dates on your county bill first. The table below explains the statewide pattern property owners usually need to understand.
| Date / Event | What It Means | What To Do |
|---|---|---|
| January 1 | Market value reflects the property’s worth as of January 1 of each tax year | Keep sale, improvement, damage and condition evidence tied to the correct valuation date. |
| Assessment notice | Starts the appeal clock | File any valuation appeal within 30 days of the notice date. |
| September 1 | County treasurer pages commonly say Wyoming taxes are billed and due September 1 | Watch mail and county portal for your tax notice. |
| November 10 | First half of taxes due | Pay first installment or verify escrow posting. |
| May 10 | Second half of taxes due the following calendar year | Pay second installment or verify escrow payment. |
| First Monday in June | Property Tax Refund Program application deadline | Apply through DOR or county treasurer route if eligible. |
| Fourth Monday in May | Veteran property tax exemption deadline | Contact county assessor annually if claiming the veteran benefit. |
How to estimate Wyoming property tax
Wyoming uses market value, assessment rate and mill levy. For residential homes, the key number is 9.5% of market value.
Residential property
Residential taxable value equals market value × 9.5%.
Commercial property
Commercial taxable value is also generally market value × 9.5%.
Industrial property
Industrial taxable value equals market value × 11.5%.
| Example | Taxable Value Step | Tax Estimate Step |
|---|---|---|
| $300,000 residence | $300,000 × 0.095 = $28,500 taxable value | $28,500 × total mill levy as decimal |
| $500,000 residence | $500,000 × 0.095 = $47,500 taxable value | $47,500 × total mill levy as decimal |
| $750,000 commercial property | $750,000 × 0.095 = $71,250 taxable value | $71,250 × total mill levy as decimal |
| $1,000,000 industrial property | $1,000,000 × 0.115 = $115,000 taxable value | $115,000 × total mill levy as decimal |
1
Find market value from the county assessor
Use the value as of January 1 of the tax year.
▾
Search your county assessor property record and note market value, property class, land value, improvement value and taxable value.
2
Apply the correct assessment rate
Residential and commercial are usually 9.5%; industrial is 11.5%.
▾
For a home, multiply market value by 0.095. For industrial property, use 0.115. If property classification is unclear, call the county assessor before estimating.
3
Multiply taxable value by total mill levy
Mill levies are local and change by tax district.
▾
If the total tax rate is 68 mills, use 0.068 as the decimal. Example: $9,500 taxable value × 0.068 = $646.00 estimated tax.
Wyoming property tax relief, owner-occupied exemption, refund and veteran programs
Wyoming has several different relief routes. They have different offices, deadlines and eligibility rules, so users should not treat them as one single homestead exemption.
2026 owner-occupied exemption
Wyoming’s Residential Affidavit Claim says qualifying owner-occupied single-family homes may claim 25% of fair market value, limited to the first $1,000,000.
Property tax refund
The DOR refund program is for eligible residential taxpayers. Annual application is required and the deadline is the first Monday in June.
Veteran exemption
Administered by county assessors and treasurers. Deadline for property tax exemption is the fourth Monday in May.
County-option deferral
Wyoming DOR says the deferral program is county-option and currently only Teton County authorizes it for residents of Teton County.
Refund timing
DOR’s refund page notes refunds will be issued between July 1 and September 30.
Assessor review
The owner-occupied affidavit process is reviewed by the local county assessor to confirm qualification.
| Program | Where To Apply | Key Deadline / Rule |
|---|---|---|
| Residential Affidavit Claim | Wyoming Residential Affidavit Claim | Beginning tax year 2026; must own and reside in qualifying single-family residential property. |
| Property Tax Refund Program | County Treasurer or Wyoming Department of Revenue | First Monday in June; timely paid taxes, income, asset and residency rules apply. |
| Veteran’s Property Tax Exemption | Local County Assessor | Fourth Monday in May; veteran or surviving spouse must contact assessor annually. |
| Property Tax Deferral | Participating county assessor | County option; DOR notes currently only Teton County authorizes it. |
1
File owner-occupied affidavit if eligible
This is the major 2026 homeowner action.
▾
Open the Wyoming Residential Affidavit Claim. The program covers eligible houses, condominiums, townhouses, manufactured homes and mobile homes used full-time by the owner, subject to requirements and county assessor review.
2
Use refund program after taxes are paid
Refund program is not the same as nonpayment.
▾
Open Wyoming DOR’s Property Tax Refund Program or Wyoming Property Tax Refund System. Confirm income, asset, residency and paid-tax rules before applying.
3
Veterans should contact county assessor early
Annual contact is required under DOR guidance.
▾
Use the county assessor for the veteran exemption. Prepare proof of qualifying service, DD Form 214 or qualifying medal documentation, disability verification if applicable and current Wyoming residency information.
How to appeal a Wyoming property assessment
A Wyoming assessment appeal is about market value, not the tax rate. Your strongest case is based on sales, appraisal facts, condition issues, wrong property characteristics or classification problems.
Appeal checklist
- 1Read the assessment notice date. Wyoming DOR says appeals must be filed no later than 30 days from the date of the assessment notice.
- 2File with the county assessor. Use the assessor in the county where the property is located.
- 3Argue market value, not the tax rate. DOR says the appeal must address market value, not mill levy or tax rate.
- 4Include evidence. Add comparable sales, recent appraisal, photos, repair estimates, incorrect square footage or condition proof.
- 5Know the next level. If you disagree with the County Board of Equalization, you may appeal to the State Board of Equalization.
1
Review the county assessor record first
Look for factual errors before value arguments.
▾
Check square footage, acreage, building type, year built, condition, quality, additions, finished basement, outbuildings, land classification, property use and comparable sales.
2
Talk to the assessor before the formal deadline
Do not let the 30-day window expire.
▾
Contact the county assessor and ask how the market value was developed. If the value cannot be resolved informally, file the appeal before the 30-day deadline.
3
Build a market-value evidence packet
Evidence beats frustration.
▾
Useful evidence includes comparable sales near the valuation date, independent appraisal, closing statement, condition photos, contractor estimates, square footage proof, wrong land classification, income data for income-producing property and recent sale information.
4
Appeal the County Board decision if needed
The State Board has its own 30-day deadline.
▾
If you disagree with the County Board of Equalization decision, Wyoming DOR says appeals to the State Board must be filed within 30 days from entry of the decision or mailing date, whichever is later.
