Rate Breakdown

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

How Property Tax Works in Routt County

Routt County assesses property value annually on January 1 based on the market value of the land and any improvements. The County Assessor’s Office uses comparable sales, cost‑approach data, and income information (for rentals) to determine the assessed value, which is typically 100 % of the market value. Once the assessed value is established, the tax‑bill is calculated by applying the combined millage rate—expressed in dollars per $1,000 of assessed value—from all taxing entities that serve the parcel (county, city, school district, fire protection, special districts, etc.). For example, a residential property with a $350,000 assessed value and a combined millage rate of 75 mills would owe $350,000 ÷ 1,000 × 75 = $26,250 in property taxes for the year.

Available Exemptions

Colorado law provides several exemptions that can lower the taxable portion of your property. In Routi County you may qualify for one or more of the following:

• Homestead Exemption: Reduces the assessed value of your primary residence by up to $200,000, lowering the amount subject to tax. The exemption is automatic for owner‑occupied homes, but you must file a homestead declaration to receive the full benefit.
• Senior Citizen Exemption (Senior/Disabled Exemption): Residents age 65 or older, or those who are permanently disabled, may receive an additional exemption of up to $50,000 on the assessed value of their primary residence.
• Disability Exemption: Qualifies if you have a qualifying disability as defined by state law, offering the same $50,000 reduction as the senior exemption.
• Veteran Exemptions:
  • Disabled veterans may receive a $25,000 exemption for each qualifying disability rating.
  • Surviving spouses of veterans killed in action are eligible for a $100,000 exemption.

All exemptions require a completed application and supporting documentation to be submitted to the Routt County Assessor’s Office by July 1 of the tax year.

Payment Schedule & Deadlines

Routt County property taxes are due in two installments:

• First Installment: Due September 15. This payment represents half of the total tax bill.
• Second Installment: Due December 31. Paying by this date avoids any penalties.

If you fail to pay an installment by the due date, a 10 % penalty is added to the overdue amount, plus interest accrued at the legal rate set by the Colorado Department of Revenue. The county also offers a limited “early‑bird” discount of 5 % for payments made before August 1. Property owners may elect to pay the full amount in a single lump sum at any time before the second installment deadline.

Appealing Your Assessment

If you believe your assessed value is inaccurate, you have the right to protest. Follow these steps:

• File a Notice of Protest: Submit the form to the Routt County Assessor’s Office no later than July 31 of the assessment year.
• Gather Evidence: Compile recent sales of comparable properties, independent appraisals, or photographs showing condition differences.
• Hearing: Attend a hearing before the County Board of Equalization, typically scheduled in August or September. You may present your evidence and answer questions.
• Decision: The board issues a written decision within 30 days. If you disagree with the outcome, you may appeal to the Colorado Board of Assessment Appeals.

Prompt action and thorough documentation improve the likelihood of a successful protest, helping ensure you only pay taxes on a fair, market‑based valuation.
