The Assessor's Office locates, appraises and records all of Denver's real and personal properties in accordance with the Colorado Constitution, State statutes, and Board of Equalization procedures. The Assessor certifies valuations to 126 special tax districts and tracks values and annual tax increments within the city's 22 tax increment financing (TIF) projects. The division prepares and delivers the tax warrant to the Treasurer, maintains records on senior citizen and other tax exemptions, generates value notices for all taxpayers, and processes written and in-person valuation protests and appeals.
The Assessor's Office employees are working remotely. Citizens may contact us via email at email@example.com as opposed to calling or coming to our office. We encourage you to email us with any questions you may have. Our team monitors this email continuously and will respond.
We appreciate your patience during this unprecedented time.
The Constitution and state laws of Colorado have established real and business personal property assessment procedures and requirements. The values determined by the Assessment Division for real and personal property are used in the calculation of property tax bills. The revenue raised through these property taxes is used to help pay for all public services including police, schools, libraries, and fire protection.
For residential properties, Division appraisers study the sales of homes similar to yours which sold within a specific 24-month period. For commercial and industrial properties, the cost, market and income approaches are considered and for business personal property, values are based on the asset information submitted directly by business owners.
Under Colorado law, all real property (land, buildings, improvements, etc) must be re-appraised every two years. This occurs in each odd-numbered year (2017, 2019, etc). The Assessment Division studies the prices of properties which sold during the 24-month period ending on June 30 of the year prior to the reappraisal. For example, 2019 values are based on properties which sold between July 1, 2016, and June 30, 2018. New values are set each year for personal property owned by businesses based on the information annually submitted by the taxpayers on personal property declarations.
The Assessment Division does not set property taxes or collect payments. However, we can provide the following general information about how your most recent property tax bill (2019 taxes payable in 2020) was calculated and how to estimate taxes.
To calculate taxes, Actual Value is adjusted by the appropriate Assessment Rate to determine its Assessed Value. Commercial properties are multiplied by 29% (0.2900) and residential properties, including apartments, by 7.15% (0.0715).
The Assessed Value (less any exempted amount) is next multiplied by the applicable Tax Rate. In Colorado, tax rates are expressed as a decimal fraction of a dollar for every one dollar of Assessed Value. Known as millage or mills, one mill is 1/1,000th of a dollar or $0.001 (1/10th of a penny). Millage greater than one mill is usually written as a whole number followed by three digits to the right of a decimal point.
In 2019, Denver's combined general millage or Mill Rate including Denver Public Schools and Urban Drainage District is 72.116 mills or a tax rate of 0.072116 for every $1 of assessed value.
In 2019, the typical single family Denver home was valued at about $430,000. As a result, the property tax calculation for a typical residential owner was:
Actual Value x Assessment Rate x Mill Rate (Tax Rate) = Taxes
Typical Denver Residence
$430,000 x 0.0715 x 0.072116 = $2,217.21
As shown above, the tax calculation has three parts. The Actual Value comes from the Assessor and is shown on the NOV mentioned above. Assessment Rates are set annually by the State Legislature. Tax Rates are set in December each year by taxing authorities like the City and County of Denver, Denver Public Schools and others listed on the tax bill. For more information regarding how tax rates are determined, contact the taxing authorities directly.
In order to determine new values for residential property (including single-family, multi-family and apartment properties) all Colorado assessors are required by law to use only the market approach to value. For 2019 property values, the sales prices of homes similar to yours which sold between July 1, 2016, and June 30, 2018, were studied. If the sales prices of those homes went up, then the assessed value of your home likely showed an increase.
The Assessor does not set property taxes or mill rates. Property taxes are determined by multiplying a property's assessed value by the millage or mill rate. Mill rates are set in December of each year by the various taxing authorities (City and County of Denver, Denver Public Schools, and any special districts).
State laws (TABOR for example) as well as other voter-approved measures impact the mill rate that is eventually adopted by each taxing authority. It is not possible to determine whether property taxes will increase or decrease until the various mill rates are determined in December of each year.
The Assessor determines the "actual" (market) value for all real and personal property. Actual value is then reduced by a percentage to derive the "assessed" value. For all Colorado commercial and business personal property, the assessment percentage is 29%. For example, if a commercial or business personal property owner receives a notice from the Assessor stating that the actual value of his/her property is $100,000, its assessed value would be $29,000 (100,000 x 0.29). For all residential property a new assessment percentage is determined each year by the state legislature. The current percentage for residential property is 7.15%. Thus, a house with an actual value of $100,000 would have an assessed value of $7,150 (100,000 x 0.0715). Your property's actual value multiplied by its assessment percentage yields its assessed value. Assessed value times mill rate, produces your annual property tax bill.
