The Constitution and state laws of Colorado established real and business personal property assessment procedures and requirements. The values determined by the Assessor Department 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 schools, police, libraries, and fire protection.
For residential properties, the Assessor Department 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 while business personal property values are based on the asset information submitted directly by business owners.
To obtain value information along with other data on a property, click on the Property Search Links on the Assessor webpage. The simplest search is the Property Records Search (EagleWeb). Click on that link and when the EagleWeb homepage pops up, press the 'Enter EagleWeb' tab ONCE and wait.
Under the Situs Address bar, enter your HOUSE NUMBER only (especially for residential, less is more) and press enter. Select from the search results.
The Assessment Department does not set property taxes or collect payments. However, we can provide the following general information about how your most recent property tax bill (2022 taxes payable in 2023) 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), single-unit residential properties are multiplied by 6.95% (0.0695) and apartments are multiplied by 6.80% (0.068).
The Assessed Value (less any exempted amount) is next multiplied by the applicable Tax Rate, sometimes referred to as Mill Levy. In Colorado, tax rates are expressed as a decimal fraction of a dollar for every one dollar of Assessed Value. Known as a mill, one mill is 1/1,000th of a dollar or $0.001 (1/10th of a penny) and is usually written as a whole number followed by 3 digits to the right of a decimal point.
In 2022, the combined mill levy in the Broadlands area of Broomfield is 122.872 mills or a tax rate of 0.122872 for every $1 of assessed value. Using a home value of $530,000, here is a property tax calculation:
Actual Value x Assessment Rate x Mill Levy (Tax Rate) = Taxes
$530,000 x 0.0695 x 0.122872 = $4,525.99
As shown above, the tax calculation has 3 parts. The Actual Value comes from the Assessor and is show on the NOV mentioned above, Assessment Rates can be set annually by the State Legislature. Tax Rates are set in December each year by taxing authorities like the City and County of Broomfield, the school districts, North Metro Fire Protection and others listed on the tax bill. For more information regarding how tax rates are determined, contact the taxing authorities directly.
Notices of Valuation (NOV) for real property are mailed out every reappraisal (odd numbered) year no later than May 1. The appeal form is included with the NOV. If you wish to appeal your value, provide comparable sales (not listings) of similar homes in your area that have occurred during the statutory sales period.
For tax years 2023 and 2024, the sales period is from July 1, 2020 through June 30, 2022. Email or mail the signed form with sales or other supporting documentation to the assessor by June 8.
For more information and to review sales used by the Assessor department, visit the Appeal Information page.
NOVs are only mailed out in intervening (even) years when there has been a change in value to the property due to things like finished basements, additions, etc. Select this link to access a 2023 appeal form.
Under Colorado law, all real property (land, buildings, improvements, etc.) must be re-appraised every two years. This occurs in each odd-numbered year (2021, 2023, etc.). The Assessor Department 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, the new 2023 values are based on properties which sold between July 1, 2020 and June 30, 2022, and based on what was there as of January 1, 2023 (assessment date). While we assess the property based on what was there on the assessment date of January 1, 2023 we base that value on the appraisal date of June 30, 2022. The appraisal date reflects the market data on that data.
New values are set each year for business personal property owned by businesses based on the information annually submitted by the taxpayers on personal property declarations.
All property in Colorado is valued as it exists on January 1 of the current year. January 1 is the Assessment Date. If a structure is not fully built on that date, a partial value reflecting the percentage of completion is used. The value is based on what it would be worth as of June 30, 2022, the Appraisal Date.
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 the 2023 Property Tax Year, the residential property assessment rate is 6.765%. For example, if a homeowner receives a Notice of Valuation from the Assessor stating that the actual value of their property is $530,000, its assessed value would be $36,850 rounded (530,000 x 0.06765). See FAQ "What are the assessment rates on all property types?" for the rest of the assessment rates.
Mill levies are set by the taxing authorities (City and County of Broomfield, North Metro Fire Dept., school districts, metro districts, etc.) in which your property is located. Areas where these tax authorities overlap are put into Tax Areas in the assessor's database. Every property in a tax area is taxed by that area's total net mill levy. The property tax revenues support services in your specific area. The assessor reports the total assessed value to the tax authorities every year and the tax authorities determine their budget and send their mill levy certification to the County no later than December 15.
Mill levies are finalized at the end of December each year and posted early January. Mill Levies by Tax Area/District Report
The taxing authorities are school districts, special districts, etc. in the area your property is located. They hold annual public budget hearings to determine the funds needed for next year's operations, which will determine the mill levy. Most hearings are in the autumn. Being present at the budget hearings makes you more involved and informed about the cost and quality of services provided. Click here for Tax Authority Contact Info.

Researching to determine your property's mineral rights is not a function of the assessor's office but we can offer a general direction from where to begin your search. Mineral rights may or may not appear on your deed. Deeds are recorded for public record at the Clerk & Recorder’s Office. Since Broomfield has only been a county since 2001, our records are not complete so you may need to contact the legacy county (the county your property was located in before 2001 - Boulder, Weld, Jefferson or Adams).
Due to the complexity of mineral rights research, you may need to hire a real estate attorney or a title company to assist you.
Property lines can only be determined by a licensed surveyor. The City and County of Broomfield does not offer this service.
If your property is within a platted subdivision, you may view the recorded plats from our GIS department's Subdivision Plat Maps page. Parcel maps can be viewed through our Aerial Parcel Search .
