Summit County, CO - Official Website (2024)

Assessor Duties

The Assessor’s Office is charged with discovering, listing, classifying and assessing all property within Summit County, and must follow state laws when meeting these responsibilities. The Assessor’s goal is equalization of property values, which causes the burden of taxes to be distributed fairly and equitably between property owners. Every odd-numbered year, all properties in Colorado, including Summit County, are reappraised.

Intervening year (2024)

2024 is an intervening year. Most properties do not change value from a reappraisal year to an intervening year. However, properties with intervening year conditions such as new construction, remodels or additions, change in the use of the land, installation of on-site improvements, or other changes to the property will receive a new value in the intervening year. Additionally, if errors or data corrections were discovered, the property will receive a new value, reflecting those corrections.

The County Treasurer is responsible for mailing tax bills and collection of taxes. In Colorado, property taxes are paid in arrears. Property Tax Notices are a static snapshot of ownership and value as of a certain date at the end of the year. Please use the GIS Parcel Query Tool to view current (dynamic) property information.

Contiguous Residential Land

In 2021, the Colorado State Legislature amended the definition of residential land through House Bill 21-1061 (HB21-1061). It changed some of the requirements that had been recently clarified by the Colorado Supreme Court. Residential land is defined in § 39-1-102(14.4)(a), C.R.S., as “a parcel of land upon which residential improvements are located.” The definition includes contiguous parcels under § 39-1-102(14.4)(a)(I)(C). The definition has the following requirements:

1. The parcel of land must be contiguous with the residential parcel
2. The parcel of land must have identical ownership based on record title
3. The parcel of land must contain a related improvement that is essential to the use of the residential improvement.

Section 39-1-102(14.4)(a)(III) defines:

• Contiguous to mean parcels that physically touch; except that contiguity is not interrupted by an intervening local street, alley, or common element in a common interest community, and
• Related improvements to mean an improved driveway or improvement other than a building, or that portion of a building designed for use predominantly as a place of residency by a person, a family, or families.

Definition of the word “Essential” per Black’s Law Dictionary. Abridged Sixth Edition, Copyright 1983

• Indispensably necessary; important in the highest degree; requisite.
• That which is required for the continued existence of a thing.

Legislation Affecting Property Taxes

Senate Bill 23B-001

This bill, passed during the November 17th Special Session, makes adjustments to the already enacted House Bill 22-238. These changes are as follows:

• Residential assessment rate reduced to 6.7 percent.
• $55,000 reduction to actual value on residential properties for 2023 only.¹
• All other changes enacted within HB 22-238 will remain the same.

House Bill 22-238

Since the Gallagher Amendment was repealed in November 2020, the State Legislature has been setting the assessment rates that determine what percent of actual value your property tax will be based on. The current bill in place, HB22-238, provides for:

• $15,000 (altered by SB 23B-001) reduction to actual value on residential properties (includes residential vacant land)
• $30,000 reduction to actual value on commercial improved properties
• Residential assessment rate changed to 6.765% (altered by SB 23B-001) from 6.95%
• Commercial and vacant land assessment rate changed to 27.9% from 29%

¹ "Or the amount that causes the valuation for assessment of the property to be to $1,000."

Property Tax Calculation

2023 Property Taxes become Due and Payable in 2024

The County Treasurer is responsible for mailing tax bills and collection of taxes. In Colorado, property taxes are paid in arrears. The example below illustrates how to estimate 2023 property taxes for a residential property valued at $1,000,000, pursuant to SB 23B-001.

Actual Value Minus Reduction = Reduced Actual Value
$1,000,000 - $55,000 = $945,000 2023 Actual Value

Reduced Actual Value X Residential Assessment Rate = Assessed Value
$945,000 X 0.067 (6.7%) = $63,315 Assessed Value

Assessed Value X Mill Levy = Tax Amount (paid in arrears)
$63,315 x 0.057128 (for 2022 mill levy of 57.128) = $3,617.06 tax estimate
