Sample Property Tax Report for a Boulder County, CO property

The Colorado Constitution and the Colorado Revised Statutes are the legal foundation upon which all valuations for assessments are determined. The County Assessor is the official who is responsible for the discovery, listing, classification, and valuation of all taxable property within each county, except public utility property which is the responsibility of the Division of Property Taxation.

Market Value

Market value has been defined by The Supreme Court as the sale price of real estate as agreed upon between a willing buyer and willing seller, with neither being under duress to buy or sell.

Land value $1,000,000
Structure value + $1,980,000
Market value = $2,980,000
Assessed Value

A property's assessed value is a percentage of its market value, 7.96% for residential property and 29% for non-residential properties. Each odd numbered year the residential assessment percentage is subject to change by the Colorado Legislature, as prescribed by the Gallagher Amendment. The change in percentage maintains the present balance of the tax burden between residential and all other taxpayers.

Land assessed value $79,600
Structure assessed value + $157,608
Assessed value = $237,208
Exemptions And Taxable Value

Exemptions and deferrals are available in Boulder County, which may lower the property's tax bill. These are deducted from the assessed value to give the property's taxable value.

We have no information about whether any exemptions currently apply to this property. Therefore, the taxable value will be equal to the assessed value.

Property Tax

Property tax is calculated by multiplying the property's taxable value by the millage rates applicable to it and is an estimate of what an owner not benefiting from any exemptions would pay. The rates are expressed as millages (i.e the actual rates multiplied by 1000).
Actual taxes might differ from the figures displayed here due to various abatement and financial assistance programs or to non ad-valorem taxes.

Boulder County $237,208 * 25.1200‰ = $5,958.66

Boulder Valley School District $237,208 * 45.3720‰ = $10,762.60
