Weld County Property Tax Appeal, Colorado

Rob Hartley·Updated May 15, 2026

Weld County is located in the U.S. state of Colorado, and as of the 2020 census had a population of 328,981, with Greeley serving as the county seat. Weld County's 2026 population is estimated at 385,572, making it the 7th largest county in Colorado. Weld County is Colorado's leading producer of cattle, grain and sugar beets, the richest agricultural county in the United States east of the Rocky Mountains, and an important area of oil and natural gas production in the Denver-Julesburg Basin. Weld County homeowners pay an average of $1,995 in annual property taxes on median home values of $412,200, resulting in an effective tax rate of 0.48% , which puts the county's median annual tax bill below the national median of $2,400 — but with home values rising sharply during the 2025-2026 reassessment cycle, appeals can yield meaningful savings.

On the typical Weld County home, valued near $412,200 at the county’s effective tax rate of 0.48%, an over-assessment of even 10% means you are overpaying year after year until you appeal it. Here is how to find out if yours qualifies.

2026 Appeal Deadline: June 8, 2026

Between May 1st and June 8th, per C.R.S. §39-5-122(1), you may appeal your real property value. Between June 15 and June 30, you may appeal your business personal property or oil and gas value.

How Weld County Assesses Property

6.7%of market value

Assessed by: Weld County Assessor's Office

Assessment cycle: biennial

Notices typically mailed: May 1

Colorado assesses residential property at 6.70% of actual value (rate adjusted periodically by legislature; 6.7% for 2025-2026). For example, on a home at Weld County's median market value of $412,200, the assessed value would be approximately $27,617 (6.7% × $412,200), which at the county's effective property tax rate of 0.48% on market value produces an annual tax bill of roughly $1,979. Even a 10% over-assessment on a home at this value could mean paying nearly $200 more per year than warranted.

The Appeal Process

Appeals are heard by the County Board of Equalization. The taxpayer must be notified of these hearings, must be given the opportunity to attend, and must be allowed to present witnesses and other evidence. The CBOE must conclude hearings and render value decisions on or before August 5th and must mail their determination within five business days of making their decision.

Review your Notice of Valuation mailed by the Weld County Assessor on or around May 1, 2026, and verify the property record card for errors in square footage, bedroom/bath count, condition, or land classification.

Gather supporting evidence including 3-5 comparable sales from the statutory data-collection period (July 1, 2022 through June 30, 2024 for the 2025-2026 cycle), photos documenting property defects, and any repair estimates.

File your protest with the Weld County Assessor between May 1 and June 8, 2026, using the online appeal portal at apps.weld.gov/assessor/appeal/, by mail, in person, or by email to assessor@weld.gov.

Receive the Assessor's Notice of Determination — if you disagree with that decision, file an appeal with the Weld County Board of Equalization (CBOE) postmarked or delivered no later than July 20, 2026.

Attend your CBOE hearing in late July through early August, where you may present witnesses and evidence; the CBOE must render decisions on or before August 5 and mail determinations within five business days.

If still unsatisfied, escalate within 30 days of the CBOE decision by filing with the Colorado Board of Assessment Appeals (BAA), filing in Weld County District Court, or electing binding arbitration through the County Commissioners.

Required form: Real Property Notice of Valuation Protest Form (provided by the Weld County Assessor) or a written letter of disagreement referencing the parcel/schedule number

If you receive an unfavorable Notice of Determination from the Assessor, you have until July 20, 2026 to escalate the matter to the Weld County Board of Equalization.

How do I file a property tax appeal in Weld County online?

How much is the senior homestead exemption worth in Weld County?

For those who qualify, 50 percent of the first $200,000 of actual value of the applicant's primary residence is not taxable. That means up to $100,000 of your home's value is exempted, which at Weld County's effective rate of 0.48% saves a qualifying senior approximately $480 per year. To qualify, you must be at least 65 by January 1 and have owned and occupied the home for at least 10 consecutive years. Applications are due by July 15, 2026 and only need to be filed once.

What happens at a Weld County Board of Equalization hearing?

The Weld County Board of Commissioners constitutes a County Board of Equalization (CBOE) for the adjustment and equalization of assessments among the several taxpayers of Weld County, Colorado, and to hear appeals from the determination of said assessments fixed and made by the County Assessor of Weld County. The taxpayer must be notified of these hearings, must be given the opportunity to attend, and must be allowed to present witnesses and other evidence. The CBOE must conclude hearings and render value decisions on or before August 5th and must mail their determination within five business days of making their decision. Hearings are typically short — bring printed evidence packets with comparable sales and photographs.

How much can I save by appealing my property taxes in Weld County?

Successful appeals save homeowners $718 per year on average in Weld County, though savings vary widely based on the magnitude of the over-assessment. Weld County homeowners pay an average of $1,995 in annual property taxes on median home values of $412,200, resulting in an effective tax rate of 0.48%. A 10-15% reduction in assessed value on a median-priced home would translate to roughly $200-$300 in annual savings, and savings compound year after year because the reduced value typically rolls forward to the next assessment cycle.

What evidence do I need for a Weld County property tax appeal?

The strongest evidence is 3-5 sales of comparable homes that closed during the statutory data-collection period of July 1, 2022 through June 30, 2024 for the 2025-2026 cycle. Previous appraisals, expert opinions, and appraisals for similar properties may be attached to the appeal as supporting documentation. Photographs documenting deferred maintenance, foundation cracks, outdated finishes, or other condition issues, plus contractor repair estimates, strengthen condition-based arguments. Also bring a copy of your property record card from the Assessor's website highlighting any factual errors in square footage, lot size, or features.

What if I miss the June 8 protest deadline in Weld County?

If the date for filing any document falls upon a Saturday, Sunday, or legal holiday, it shall be deemed timely filed if postmarked on the next business day per C.R.S. 39-1-120(3). Outside of that grace, missing the June 8 real property deadline generally forfeits your right to appeal the current year's valuation through the standard protest process. However, you may still file an abatement petition with the County Commissioners within two years for clerical errors, illegal levies, or overvaluation that you can document. If you receive a Special Notice of Value, you have 30 days from the date at the top of the notice to appeal the value.

Applications must be submitted to the Weld County Assessor between January 1 and July 1, 2026 with an attached VA Benefit Summary Letter.
