Whether you are a real estate professional, a prospective homebuyer, or a local resident looking to budget effectively, navigating residential property taxes across Denver and its surrounding suburbs requires cutting through complex financial jargon. Here is a breakdown of how Denver property taxes work, the specific calculation formulas and key terminology used across Colorado, and exactly where your tax dollars are spent.
Denver real estate market trends & housing costs
Located in Denver County, the City of Denver sits at the center of a bustling metro area home to over three million residents—a population projected to reach 3.6 million by 2030. Strong job growth, championship sports teams, and abundant mountain recreation make the Mile High City an attractive destination for homeowners and real estate professionals alike.
Denver’s residential real estate market remains highly competitive. The median sales price for a single-family home sits around $725,657, while condos and townhomes typically range from $330,000 to $625,000.
While properties stay on the market for a median of 43 days, buyers generally pay full asking price—or slightly below—for typical homes. However, top-tier properties move quickly, often going under contract in as little as 6 days, with roughly one-third of single-family homes selling above list price due to strong buyer demand.
Understanding core property tax terminology
To make sense of your tax bill, it helps to start with the foundational concepts defined by the Colorado Division of Property Taxation:
- Property classification: The county assessor classifies every parcel based on its primary physical use on January 1 each year. Residential property includes single-family homes, condominiums, townhomes, and multi-family apartments.
- Actual market value: The estimated fair market value established by the county assessor using the market approach (analyzing comparable sales from an 18-month window ending June 30 of even-numbered years).
- Assessment rate: A statutory percentage set by the state legislature that reduces the actual market value down to a taxable base before tax rates are applied.
- Assessed value: The fraction of your home’s actual value subject to taxation (Actual Market Value times the Assessment Rate).
- Mill levy (tax rate): The combined tax rate set by local governing bodies (city council, school boards, and special districts) to fund their annual operating budgets. One mill = $1 per $1,000 of assessed value (or 0.001).
When is your home reassessed for property taxes?
Colorado reassesses real estate every odd-numbered year using home sales from the previous 18 months. Because tax values reflect past sales data rather than real-time conditions, your tax bill can still go up even when current market prices stay flat. This means the next reassessment of property values will take place in 2027.
What are Denver’s current residential property tax rates?
Denver’s overall effective residential property tax rate falls between 0.48% and 0.55% of a home’s actual market value. To see how that percentage is derived, we look at the two distinct components set by state law and local authorities: assessment rates and mill levies.
Assessment rates
Instead of taxing a home’s full market value, Colorado applies reduced statutory percentages to determine the taxable assessed value. Under state tax rules, residential real estate relies on two distinct assessment rates:
- Local government assessment rate: 6.8% of actual market value
- School district assessment rate: 7.05% of actual market value
Mill rates (aka tax rates)
In Denver’s baseline taxing area (District 100), local tax rates break down into the following mill levies:
- Local government mill levy (27.328 mills / 0.027328 multiplier): Covers City and County of Denver municipal operations, emergency services, and regional flood control.
- School district mill levy (52.274 mills / 0.052274 multiplier): Funds public education operations and facility maintenance for Denver Public Schools.
- Combined baseline mill levy (79.602 mills / 0.079602 multiplier): Represents the total standard tax rate, though properties located in specific special metro development districts may see additional local mills added to this baseline.
How to calculate your property taxes in Denver
To determine the total annual tax bill for a $725,000 home, the taxes are calculated step-by-step using the two statutory assessment rates and Denver’s baseline mill levies:
- Calculate the Local Government Tax: Multiply the $725,000 market value by the 6.8% local assessment rate to determine a local assessed value of $49,300.00. Multiplying $49,300.00 by the local mill levy rate of 27.328 mills (0.027328) results in a local government tax of $1,347.27.
- Calculate the School District Tax: Multiply the $725,000 market value by the 7.05% school assessment rate to determine a school assessed value of $51,112.50. Multiplying $51,112.50 by the school mill levy rate of 52.274 mills (0.052274) results in a school district tax of $2,671.86.
- Combine both amounts to find the total annual tax due: Add $1,347.27 for local government and $2,671.86 for the school district to get a total property tax bill of $4,019.13 per year.
- Determine your effective property tax rate: Divide $4,019.13 by the $725,000 market value to find an effective residential property tax rate of roughly 0.55% (keep in mind this percentage will ultimately depend on your home’s actual market value and taxing district).
Denver property tax payment schedule
According to the City and County of Denver Treasury Department, property owners should track the following annual key dates to manage payments, apply for exemptions, and submit appeals:
- January: Tax statements mailed to property owners.
- Last day of February: First-half tax payment due.
- April 1: Property tax deferral applications due.
- April 30: Full tax payment due (single-payment option).
- May 1 (Odd-numbered years): Notices of Valuation mailed.
- June 15: Second-half tax payment due.
- July 15: Senior and Disabled Veteran Exemption applications due.
- November 15: Property valuation protests due.
Where do your residential property tax dollars go?
Every dollar collected from property taxes remains within the county where it is generated. Property taxes do not fund any state-level government services.
- Public K-12 schools (Denver Public Schools): Consumes the largest share (~45% to 50%), directly funding school operations, facilities, and classroom supplies.
- Municipal operations & emergency services: Supports police departments, fire protection districts, street repairs, snow clearing, and local trash collection.
- Parks, recreation, & community assets: Maintains city parks (such as Washington Park and City Park), public libraries, and community recreation centers.
- Regional transit & infrastructure: Funds Regional Transportation District (RTD) transit systems, urban drainage projects, and flood prevention authorities.
Residential tax rates in surrounding suburban counties
Because Denver County operates as a unified City and County, its municipal structure is consolidated. Surrounding suburban counties feature overlapping cities, school districts, and special service districts, creating variations in effective tax rates:
| County / jurisdiction | Average effective residential rate | Homeowner considerations |
|---|---|---|
| Denver County | ~0.48% – 0.55% | Consolidated city/county structure creates a streamlined base mill levy. |
| Arapahoe County | ~0.55% – 0.65% | Rates vary depending on specific city boundaries (e.g., Centennial vs. Aurora). |
| Jefferson County | ~0.50% – 0.58% | Typically lower municipal mill levies, though local mountain fire districts vary. |
| Adams County | ~0.60% – 0.72% | Higher effective rates driven by metro district infrastructure bonds in newer suburbs. |
| Douglas County | ~0.55% – 0.62% | High median home prices produce higher dollar payments despite moderate percentage rates. |
What affects your property taxes?
Denver property taxes depend on several physical and structural factors evaluated during the county assessment. Assessors review appraisals and recent sales of comparable homes in the immediate area that sold within the 18-month data window.
Specific home characteristics that influence your assessed valuation include:
- Property classification and structural type (single-family, condo, multi-unit)
- Total square footage and lot size
- Overall property age and condition
- Room counts (number of bedrooms and bathrooms)
- Finished basements, garages, porches, decks, and outdoor amenities like pools
Can residents expect residential property taxes to rise?
Yes, Denver residents can generally expect residential property taxes to rise over time as home values increase and municipal budgets expand. While state legislative caps keep overall tax growth manageable, individual property bills can still go up—especially during two-year reassessment cycles when property values are updated to reflect past market appreciation.
Living in Denver: neighborhoods, transit, & amenities
Beyond tax calculations, evaluating Denver’s distinct neighborhoods, public school options, and regional transit networks helps clarify both the overall lifestyle and long-term financial commitments of living in the Mile High City—offering vibrant opportunities for families, young professionals, and retirees alike.
Popular residential neighborhoods

School systems
Residential properties in Denver fall within Denver Public Schools (DPS), the largest school system in Colorado. DPS utilizes an open-enrollment framework called SchoolChoice, allowing resident families to apply to schools outside their neighborhood attendance zone subject to available space.
Regional transportation & connectivity
The RTD Commuter & Light Rail connects residential districts with downtown commercial sectors and provides a direct train connection (A Line) from Union Station to Denver International Airport (DEN). Interstates 25 (north/south) and 70 (east/west) serve as the primary automotive corridors for residential commuters.
