Laramie Property Tax: Rates, Exemptions & Appeals (2026)

Direct answer: Laramie County mailed 2026 Notices of Assessment on April 15, 2026, so the residential assessment appeal deadline was Friday, May 15, 2026 — 30 days after the mail date. File with the Laramie County Assessor, 309 W. 20th St., Suite 1100, Cheyenne, WY 82001, or P.O. Box 307, Cheyenne, WY 82003-0307; the office lists assessor@laramiecountywy.gov, fax 307-633-4474, and phone 307-633-4307, but the safest filing methods are in person or mail unless the Assessor confirms email/fax filing for your case.

How assessments work in Laramie County

Laramie County values real property every year as of January 1. Wyoming requires county assessors to update property values annually, and the Department of Revenue says each property’s real-property characteristics must receive a detailed review at least once every six years. For 2026, the county says its Notice of Assessment was mailed April 15, 2026.

For a typical home, the Assessor is estimating fair market value — what the property would sell for as of January 1 — and then Wyoming applies the residential assessment ratio. Residential taxable/assessed value is 9.5% of market value. The tax bill is then: market value × 9.5% × your tax district’s mill levy.

Laramie County’s residential valuation page is unusually helpful about the local method. The office uses a Computer Assisted Mass Appraisal (CAMA) cost system, including a Boeckh appraisal program with state enhancements. Field appraisers collect property characteristics; the system estimates replacement cost new, then applies year built, effective age and condition to produce replacement cost new less depreciation. The county also divides Laramie County into appraisal neighborhoods and analyzes sales ratios in those neighborhoods to bring values to current market value.

That means your best appeal usually attacks one of three things: a wrong property record card, a neighborhood/sales comparison problem, or a condition issue the model missed. “My taxes are too high” is not enough; Laramie County specifically says you need a desired action, such as your opinion of market value as of January 1.

Whether you should appeal

Appeal if the 2026 fair market value on the notice is materially higher than what your home was worth on January 1, 2026, or if the Assessor has bad data. Start with the property record card: square footage, finished basement, garage, outbuildings, quality, condition, year built/effective age and land classification. The county says these details are reviewed during the property-review process and changes can affect final value.

Evidence that is useful in Laramie County includes a recent appraisal, arm’s-length comparable sales near the January 1 valuation date, a contractor estimate for major condition problems, photos, or documentation that the county’s record is wrong. Because Wyoming sales disclosure forms — Statements of Consideration — are confidential, you cannot simply download all sale prices. But during the 30-day appeal period, Laramie County says an appealing property owner may review the sales information used to value the property; it cannot be mailed, emailed or discussed by phone, and you may not disclose it except in the appeal.

I did not find an official Laramie County publication giving residential appeal success rates, median reductions or average savings. Treat anyone quoting a local “win rate” as anecdotal unless they can point to county or State Board data.

A realistic savings example: assume a Cheyenne home is noticed at $425,000, but good evidence supports $390,000. The market-value reduction is $35,000. Residential assessed value falls by $35,000 × 9.5% = $3,325. Using the county’s 2026 Cheyenne example levy of 76.00 mills — $76 per $1,000 of assessed value — the annual tax savings would be about $3,325 × 0.076 = $253. Your exact savings depends on your tax district; rural fire, town, school and special-district levies can differ.

Step-by-step how to file

1. Open the notice immediately. For 2026, Laramie County’s mail date was April 15, so the 30-day appeal window closed May 15, 2026. In a future year, count 30 days from the assessment-schedule mail date shown by the county.

2. Ask for an informal review first, but do not miss the deadline. Laramie County divides the process into Review and Formal Appeal. The review form is called “Request for Property Review Only.” The county says it should be completed and signed; otherwise the contact may be treated as informal and not initiate changes.

3. Bring evidence and a value. At the review, the Assessor’s staff checks your property record card for square footage, construction, finished area, outbuildings and other characteristics. Bring your appraisal, sales analysis, photos, repair estimates or other information. Give a specific requested value as of January 1, 2026.

4. If the review does not resolve it, file the formal appeal. The form name used by the county is “Official Appeal of Assessment.” Laramie County says these forms are available in the Assessor’s Office. State law also allows a written statement specifying why the assessment is incorrect. File the form or statement with the Assessor within 30 days of the assessment-schedule mail date.

5. Where to file. Physical address: Laramie County Assessor, 309 W. 20th St., Suite 1100, Cheyenne, WY 82001. Mailing address: P.O. Box 307, Cheyenne, WY 82003-0307. Published contact methods are assessor@laramiecountywy.gov, fax 307-633-4474, phone 307-633-4307. I found no county-published online assessment-appeal portal and no county-published filing fee for the Assessor-level assessment appeal.

What happens after

If the informal review succeeds, the county says you will receive either an amended schedule with updated market value and estimated tax, or notice that no change was made and that you may continue to formal appeal.

Formal appeals go to the Laramie County Board of Equalization. The county explains that the County Commissioners serve as the County Board of Equalization. A hearing date and time are set and mailed to the owner. At least 15 days before the hearing, the Assessor and the taxpayer must disclose witnesses and exchange relevant information, evidence and documents. Laramie County says hearings are generally scheduled for mid-June.

The hearing is a real evidentiary hearing, not a casual counter visit. The petitioner presents first and may offer evidence or witnesses. The Assessor or deputy then presents evidence or witnesses. Each side can question testimony, and board members may ask questions. After evidence, each side may make a brief closing statement. I did not find a county-published paper-only formal option; the county’s described formal process is a hearing. You may withdraw an appeal by written notice to the Clerk’s and Assessor’s offices.

The Board must notify participants in writing of its findings and any further appeal rights no later than October 1. If you disagree with the county board decision, Wyoming’s Department of Revenue says an appeal to the State Board of Equalization must be filed within 30 days from entry of the county board decision or the mailing date, whichever is later.

Local tips

Check exemptions before you spend all your energy on valuation. For 2026, Laramie County listed three key homeowner-related programs: Homeowners Exemption applications from Oct. 1, 2025 to Mar. 1, 2026; Longterm Homeowner’s Exemption applications from Oct. 1, 2025 to May 26, 2026; and Veteran’s Exemption sign-up from Jan. 2, 2026 to May 26, 2026.

The new Wyoming homeowner exemption is worth special attention: the state describes it as 25% of fair market value for an eligible owner-occupied single-family dwelling and associated improved land, limited to the first $1 million of value, beginning in tax year 2026. Laramie County says the homeowner application can be completed through the Wyoming Department of Revenue online system or at the Assessor’s office. The long-term homeowner exemption is for qualifying older homeowners and was 50% for tax years 2025 and 2026; call the Assessor before relying on old deadlines because 2026 legislation changes the deadline beginning after July 1, 2026. Veterans should also check the county’s veterans page and confirm annually by the fourth Monday in May.

Finally, remember the appeal is about market value, not the mill levy or your escrow payment. Tax bills are handled by the Treasurer, and Laramie County taxes are commonly payable in two halves: first half by November 10 and second half by May 10 of the following year, with an option to pay the full year by December 31 to avoid first-half interest.

When Are Property Taxes Due in Laramie County?

For current-year taxes, 50% is due September 1 and payable by November 10; the remaining 50% is due March 1 and payable by May 10 of the following year. For 2026 tax bills: first half payable by 2026-11-10; second half payable by 2027-05-10; if a due date falls on a weekend or courthouse holiday, the next business day is treated as the due date. Two-installment option: pay 50% by November 10 of the tax year and the remaining 50% by May 10 of the following year. Alternatively, pay the entire current-year tax by December 31 to avoid interest on the first half.

This is not the same as the assessment appeal deadline above. The appeal deadline is your window to contest your assessed value; the payment due date is when the resulting tax bill must be paid. Missing one does not affect the other, but missing either has real consequences — one forfeits your right to appeal for the year, the other can trigger penalties and interest.
