Weld County Property Tax Appeal, Colorado

Travis Bunn·Updated July 24, 2026

Weld County is located in northeastern Colorado with a 2026 population estimated at 385,572, making it the 7th largest county in the state. The county seat is Greeley, home to the University of Northern Colorado, with other major cities including Windsor, Evans, Firestone, and Johnstown. Property tax appeals are particularly important in Weld County given its rapid growth rate of nearly 52% since 2010 and a median home value of approximately $412,200, which is below the state median. With an effective tax rate of 0.48% to 0.54%, Weld County property taxes are significantly below the national median of 1.02%, though the median annual tax bill of approximately $1,995 to $2,688 still represents a substantial expense for homeowners, making successful appeals potentially worth hundreds of dollars annually.

How Weld County Assesses Property

6.25%of market value

Assessed by: Weld County Assessor's Office

Assessment cycle: biennial

Notices typically mailed: May (typically mailed by mid-May)

In Weld County, your property tax bill is based on your home's assessed value, not its full market value. Colorado law requires residential property to be assessed at 6.25% of its actual market value for local government purposes. For example, if your home's market value is $412,200 (the county median), at the 6.25% assessment ratio your assessed value would be $25,763, resulting in approximately $1,995 in annual taxes at the county's effective rate of 0.48%. Understanding this distinction is critical when appealing, as you must demonstrate your market value is too high, not just that your taxes feel excessive.

The Appeal Process

Appeals are heard by the County Board of Equalization. After filing your appeal, you may be invited to an informal meeting with an assessor to review your evidence. If unresolved, the County Board of Equalization will schedule a formal hearing where you present evidence, the assessor presents their valuation, and board members ask questions before rendering a decision.

Step 1: Review your Notice of Valuation received in May 2026 and compare your property's assessed value to similar properties in your neighborhood using the Weld County property search tool.

Step 2: Gather evidence to support your appeal, including recent comparable sales (homes similar to yours that sold for less between January 1, 2023 and June 30, 2024), photos of property defects, repair estimates, or appraisals showing a lower market value.

Step 3: File your appeal with the Weld County Assessor by June 8, 2026 via email (appeals@weld.gov), mail, in-person, or online at apps.weld.gov/assessor/appeal/. Include your property account number, the value you believe is correct, and all supporting documentation.

Step 4: Attend an informal review meeting with the Assessor's Office if offered. The Assessor will review your evidence and may adjust your valuation. You will receive a Notice of Determination showing the Assessor's decision.

Step 5: If you disagree with the Assessor's Notice of Determination, you may appeal to the Weld County Board of Equalization by September 15, 2026. The Board will schedule a formal hearing where you can present your evidence.

Step 6: If unsatisfied with the County Board of Equalization decision, you may appeal to the Colorado Board of Assessment Appeals within 30 days of the CBOE decision, or file a petition in district court.

Step 7: For final-level appeals beyond the county level, consult with a property tax attorney or professional to evaluate whether pursuing a State Board of Assessment Appeals or district court appeal is worthwhile based on your potential tax savings.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Weld County for 2026?

The deadline to file a property tax appeal with the Weld County Assessor is June 8, 2026. This deadline applies to appeals of the valuation or classification shown on your Notice of Valuation, which is typically mailed in May. You must submit your appeal by this date either by email to appeals@weld.gov, by mail with proof of mailing, in person at the Assessor's Office, or through the online portal. Missing this deadline means you'll have to wait until the next reassessment cycle in 2027 to challenge your valuation. If you disagree with the Assessor's Notice of Determination after your initial appeal, you have until September 15, 2026 to appeal to the County Board of Equalization.

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

Weld County offers online filing for property tax appeals through their dedicated portal at apps.weld.gov/assessor/appeal/. You can also file by email at appeals@weld.gov, which is often the fastest method. When filing online or by email, include your property account number (found on your Notice of Valuation), a clear statement of what you believe the correct value should be, and attach all supporting documentation such as comparable sales, photos, or appraisal reports. Make sure to file before the June 8, 2026 deadline. You can also mail your appeal to 1400 N 17th Ave, Greeley, CO 80631, or deliver it in person during business hours. We recommend obtaining proof of submission regardless of filing method.

What evidence do I need to win my Weld County property tax appeal?

The strongest evidence for a successful Weld County property tax appeal includes recent comparable sales of similar homes in your area that sold for less than your assessed market value. These sales should ideally have occurred between January 1, 2023 and June 30, 2024, as that's the period assessors use for the 2025-2026 valuation cycle. You should also include photos documenting any property damage, deferred maintenance, or defects that reduce your home's value. A professional appraisal conducted during the valuation period can be compelling evidence. Additionally, repair estimates from licensed contractors, documentation of incorrect property characteristics in county records (such as wrong square footage or number of bedrooms), or market trend data showing declining values in your neighborhood can strengthen your appeal.

What happens at a Weld County Board of Equalization hearing?

If you disagree with the Assessor's Notice of Determination, you can appeal to the Weld County Board of Equalization (CBOE) by September 15, 2026. The CBOE consists of the Weld County Board of Commissioners and hears appeals of property valuations set by the County Assessor. At the hearing, you'll have an opportunity to present your evidence and testimony explaining why you believe your property's valuation is incorrect. The county assessor will also present their evidence supporting their valuation. Board members may ask questions of both parties. After considering all evidence, the Board will issue a written decision either upholding the assessor's value, reducing it to your proposed value, or setting it at some other amount they determine to be fair. The hearing is typically informal but follows legal procedures. You should bring multiple copies of all evidence and be prepared to answer questions about your property and comparable sales.

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

Successful property tax appeals in Weld County save homeowners an average of $718 per year, according to recent data. Your actual savings depend on how much your property's assessed value is reduced and your property's tax rate. For example, if your home is valued at $412,200 (the county median) and you successfully reduce the valuation by 10% to $370,980, you would save approximately $200 annually at Weld County's 0.48% effective tax rate. The savings compound over time, that $200 annual savings equals $1,000 over five years. Given that about 25% of homes nationally are overassessed by an average of $1,346 annually, the potential savings make appealing worthwhile for many Weld County homeowners, especially if you have strong comparable sales evidence or your home has significant defects not reflected in the assessment.

What is the homestead exemption worth in Weld County?

Weld County offers two primary property tax exemptions for homeowners, though both are state programs. The Senior Property Tax Exemption exempts 50% of the first $200,000 in actual value (up to $100,000) for qualifying seniors age 65 and older who own and occupy their primary residence. This can save approximately $240 to $270 annually for a property at the median value, though funding for this program for tax year 2026 had not been confirmed by the Colorado General Assembly as of early 2026. The Disabled Veteran Exemption provides the same benefit, 50% of the first $200,000 in actual value, for veterans with a 100% VA disability rating and gold star spouses. The application deadline is July 15 for the senior exemption and July 1 for the disabled veteran exemption. Applications must be submitted to the Weld County Assessor's Office and can be obtained from their website at www.weld.gov or the Colorado Division of Property Taxation.

Can I appeal my Weld County property taxes if my home value hasn't changed?

Yes, you can appeal your Weld County property tax assessment even if your actual property hasn't changed, as long as you have evidence that the assessor's valuation is incorrect. Colorado conducts property revaluations every two years during odd-numbered years, with values set based on sales data from the previous period. For the 2025-2026 tax years, properties were valued based on sales between January 1, 2023 and June 30, 2024. Even if your home is unchanged, the assessor may have overestimated its market value based on inappropriate comparables, incorrect property data, or misapplication of valuation models. You can appeal by June 8, 2026 if you can demonstrate through comparable sales, an appraisal, or other evidence that the market value assigned to your property exceeds what a willing buyer would actually pay. Many successful appeals are based on showing the assessor used comparables that weren't truly similar or overlooked factors that reduce the subject property's value.

Does Weld County reassess property every year?

No, Weld County follows Colorado's statewide biennial reassessment cycle for real property, meaning residential properties are revalued every two years in odd-numbered years. The most recent reassessment occurred in 2025 and set values for both tax years 2025 and 2026, based on market conditions and sales data from January 1, 2023 through June 30, 2024. The next full reassessment will take place in 2027 for tax years 2027 and 2028. However, assessment notices are mailed annually in May even in non-reassessment years. Business personal property is revalued every year. This biennial cycle is important for appeals because you can only challenge your property's valuation during the appeal window following the mailing of your Notice of Valuation. For 2026, that window closes June 8, 2026, and if you miss it, you'll generally need to wait until the 2027 reassessment cycle to appeal unless you receive a special notice of value change.
