Rate Breakdown

Property taxes in Weld County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Weld County

Weld County property taxes are based on the “assessed value” of each parcel, which the county assessor determines each year by applying a uniform percentage (the assessment rate) to the property’s market value. Residential real‑estate is typically assessed at 7.15 % of market value, while commercial, agricultural and industrial properties have different rates. Once the assessed value is set, the county multiplies it by the combined “millage rate” – the sum of all applicable tax levies expressed in dollars per $1,000 of assessed value. For 2024‑2025 the general‑purpose millage for Weld County is about 65 mills, but schools, fire districts, water districts and special districts each add their own mills, so the final rate for a homeowner can range from 120 to 180 mills or more.

• Assessment process: The assessor’s office reviews recent sales, improvements, and land‑use data to estimate market value, then applies the statutory assessment rate.
• Tax rate (mills): Each taxing authority votes on its levy; the rates are posted annually on the county’s website and on your tax bill.
• Tax calculation: Tax = (Assessed Value ÷ 1,000) × Total Millage Rate.
• Re‑assessment: Property owners receive a notice of assessment each spring; the value can change due to renovations, new construction, or market fluctuations.

Available Exemptions

Colorado law provides several exemptions that directly reduce the assessed value (or the tax amount) for qualifying owners. These exemptions are applied before the millage is multiplied, so they can produce noticeable savings.

• Homestead exemption: Reduces the taxable portion of a primary residence by $250,000 of the assessed value (as of 2024). It is automatic for owners who occupy the property as their main home.
• Senior citizen exemption: Residents 65 years or older may qualify for a 10 % reduction of the taxable value, plus an additional $25,000 reduction if the home’s market value is under $400,000.
• Disability exemption: Disabled homeowners (physical or mental) can receive a 10 % reduction of taxable value, similar to the senior exemption, with the same $25,000 supplemental reduction for lower‑value homes.
• Veteran exemption: Qualified veterans (or surviving spouses) who are disabled or have served 15+ years may obtain a 10 % reduction of taxable value, plus the $25,000 additional reduction for homes under $400,000.

Payment Schedule & Deadlines

Weld County issues property tax bills in two installments. The first installment is due on **May 1** and the second on **November 1**. Taxes can be paid online, by mail, at a county treasurer’s office, or through an authorized third‑party processor.

• Early‑payment discount: Payments received by April 30 for the May installment qualify for a 2 % discount.
• Late penalties: A 5 % penalty is assessed on any amount not paid by the due date; an additional 6 % interest accrues monthly on overdue balances.
• Installment options: Taxpayers may enroll in an automatic electronic funds transfer (ACH) to ensure timely payment of each half‑yearly bill.
• Partial payment: If you cannot pay the full amount, contact the Treasurer’s Office before the due date to arrange a payment plan and avoid penalties.

Appealing Your Assessment

If you believe your property’s assessed value is inaccurate, Weld County provides a formal appeal process. Begin by reviewing the “Notice of Assessment” mailed each spring. If you disagree, you must file a written appeal with the **County Assessor’s Office** by **July 31** (or the date listed on the notice).

• Gather evidence: Compile recent comparable sales, independent appraisals, or photographs of any condition issues.
• Submit the appeal: Use the county’s online portal or submit a hard‑copy form, attaching all supporting documentation.
• Assessment Review Board (ARB): An ARB hearing is scheduled, typically within 30‑45 days of filing. You may present your case in person or via written statement.
• Final decision: The ARB issues a written determination. If unsatisfied, you can appeal further to the Colorado Board of Equalization or pursue judicial review.
