Rate Breakdown

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

How Property Tax Works in Grand County

Grand County property taxes are calculated by multiplying the assessed value of a parcel by the combined millage rate of all taxing authorities that serve the property. The County Assessor’s Office determines the assessed value each year, usually as 100% of the market value for residential property and a percentage (often 70‑80%) for commercial or industrial lands. Once the assessment is finalized, the tax bill is generated by applying the millage rates, expressed in dollars per $1,000 of assessed value.

• Assessed Value: The market value of the property on the assessment date, verified through comparable sales, income analysis, or cost approach.
• Millage Rate: The sum of rates set by Grand County, local school districts, municipalities, fire protection districts, and special districts. For example, a typical combined rate in Grand County hovers around 70‑80 mills (≈ $70‑$80 per $1,000 of assessed value).
• Tax Calculation: Tax = (Assessed Value ÷ 1,000) × Combined Millage Rate.

All property owners receive a tax statement in early February. The amount shown reflects the current year's rates and any assessment adjustments from the prior year.

Available Exemptions

Colorado law provides several exemptions that can lower your taxable base. Grand County adopts these statewide exemptions, and they are applied before the millage rate is calculated.

• Homestead Exemption: Reduces the assessed value of a primary residence by up to $250,000, based on the owner's net income and other qualifying criteria.
• Senior Citizen Exemption: Residents age 65 or older may claim an additional exemption of up to $250,000, provided their income does not exceed the state‑set threshold.
• Disability Exemption: Qualified disabled persons can receive a $250,000 exemption, mirroring the senior exemption’s income limits.
• Veteran Exemption: Honorable‑discharged veterans (or their surviving spouses) who are permanently disabled or over age 65 may claim a $50,000 exemption for each eligible veteran.

Exemptions are not automatic; owners must file the appropriate claim forms with the Grand County Assessor before the deadline (typically March 31).

Payment Schedule & Deadlines

Grand County collects property taxes in two installments. Timely payment avoids penalties and interest, while late payments accrue both.

• First Installment: Due June 15. A 5% discount is offered for payments made before this date.
• Second Installment: Due September 15. No discount, but the full amount must be paid.
• Late Payment Penalty: A 1% penalty plus 0.25% interest per month is assessed on any balance past the due date.
• Payment Options: Payments can be made online via the County Treasurer’s portal, by mail, or in person at the Treasurer’s office. Automatic bank drafts are also available.

Appealing Your Assessment

If you believe your property has been over‑assessed, Grand County offers a structured appeals process. Acting promptly and providing solid evidence improves the chance of a favorable outcome.

• Notice of Assessment: Review the assessment notice sent in February. You have 30 days to file a written protest.
• File a Protest: Submit the protest form to the Grand County Assessor’s Office, including comparable sales data, recent appraisals, or photographs supporting your claim.
• Informal Review: The Assessor may schedule a meeting or phone conference to discuss your protest.
• Formal Hearing: If unresolved, you can request a hearing before the County Board of Equalization within 30 days after the informal review decision.
• Further Appeal: Should the Board’s decision be unsatisfactory, you may appeal to the Colorado Board of Assessment Appeals within 30 days of the Board’s final order.

Throughout the process, maintain copies of all correspondence and ensure deadlines are met. Professional assistance from a qualified appraiser or attorney can be valuable, especially for complex commercial properties.
