Colorado property taxes by county
Across Colorado, the median owner-occupied home pays $2,602 a year in real-estate taxes on a median home value of $539,400 — an effective property-tax rate of 0.482%. That ranks Colorado #47 of 51 states and the District of Columbia (1 = highest). This page carries all 64 Colorado county-equivalents in the Census data — 64 with a published effective rate — sortable by rate, taxes paid, home value, income, or five-year change. 7 of them also carry a full detail card here — every median with its Census margin of error, both rankings, the six nearest counties, and the five-year change. It also sets out how property tax actually works in Colorado: how property is assessed, which exemptions exist and who qualifies, the deadline and body for an appeal, and the payment schedule and penalties — each hand-sourced from official Colorado sources. Figures are U.S. Census Bureau ACS 2020-2024 5-year estimates.

Median real-estate taxes ÷ median home value — a ratio of two independently-estimated medians, not a statutory (millage) rate.
How property tax varies across Colorado
Across Colorado's 64 county-equivalents with a published rate, the effective property-tax rate runs from 0.612% in Adams County down to 0.174% in Jackson County — a 3.5× spread inside a single state, which is why a statewide average tells a buyer very little.
The largest median real-estate tax bill in Colorado is $4,074 in Pitkin County, which ranks #36 of 64 by RATE — while the state's highest rate, 0.612%, is in Adams County, where the median bill is $2,962. Dollars and rate are different questions and rank counties differently.
Measured against the national median effective rate of 0.937%, 0 of Colorado's 64 ranked counties sit above it and 64 below. Colorado as a whole ranks #47 of 51 (1 = highest).
Median home value statewide is $539,400, but within Colorado it ranges from $1,139,100 in Pitkin County to $116,200 in Crowley County — the denominator of the effective rate, and the main reason two counties with similar bills can show very different rates.
Statewide, the median real-estate tax bill equals about 2.7% of median household income. That share is heaviest in Pitkin County (4.0%) and lightest in Jackson County (0.9%).
Comparing the non-overlapping Census periods 2015–2019 and 2020–2024, median real-estate taxes rose by a statistically significant amount in 56 of Colorado's 64 counties with a comparable trend, fell significantly in 0, and showed no statistically significant change in 8.

How property tax works in Colorado
Assessment, exemptions, appeals and payment are set by Colorado law and practice, so they apply to every county in the table above. Each fact is taken from an official government source and linked to it.
- How property is assessed
- The county assessor discovers, lists, classifies and values all property. Real property is revalued every odd-numbered year and personal property every year. Property is classified by its actual use on January 1. Residential property is valued using only the market approach; for tax years 2025 and 2026 the comparable sales must have occurred between January 1, 2023 and June 30, 2024. Notices of valuation are mailed by May 1. source →
- Exemptions & credits
- The senior exemption removes 50 percent of the first $200,000 of actual value for owners 65 or older on January 1 who have owned and occupied the home for at least ten consecutive years; apply to the county assessor by July 15. Veterans rated 100% permanently disabled and Gold Star spouses get the same exemption, applying by July 1. Owners 65+ and those in active military service may defer taxes, applying between January 1 and April 1. source →
- Appealing an assessment
- Present oral or written objections to the assessor, who must decide and mail a Notice of Determination. If still dissatisfied, appeal to the county board of equalization, which must notify you in writing within five business days of its decision; from there you may appeal to an arbitrator, district court, or the Board of Assessment Appeals within 30 days. The standard protest date is June 8, and counties over 300,000 population use an alternate schedule. source →
- Payment schedule & penalties
- Tax bills reflecting the preceding year's taxes are mailed as soon after January 1 as possible. Amounts greater than $25 may be paid in one payment by April 30 or in two equal payments, the first due by the last day of February and the second by June 15. If the tax amount is $25 or less, payment in full is due April 30. source →
- Why rates vary within the state
- Colorado splits the calculation three ways: the assessor establishes the actual value and the classification, the Colorado Constitution has the general assembly determine the assessment rate, and the taxing entities control the mill levies. A tax bill is the product of those three components, so a change in any one moves the bill. source →
- What makes this state's system distinctive
- Beginning in 2025 Colorado residential property carries two assessment rates on the same bill, one used to calculate local government assessed value and a second for school districts. For 2026 they are 6.8 percent and 7.05 percent, so a $275,000 home has a local-government assessed value of $18,700 and a separate school-district assessed value of $19,388. source →

Frequently asked questions
- What is the average property tax rate in Colorado?
- Statewide, Colorado's effective property-tax rate is 0.482% — the state median real-estate taxes ($2,602) divided by the state median home value ($539,400), from the Census ACS 2020-2024 5-year estimates. The national figure is about 0.937%, which puts Colorado at #47 of 51 (1 = highest). Individual counties vary widely; the table above shows every one.
- Which Colorado county has the highest property taxes?
- By effective rate, Adams County is highest in Colorado at 0.612% (median bill $2,962), and Jackson County is lowest at 0.174% (median bill $416). Ranked by dollars paid rather than rate the order changes, because home values differ so much across the state — the table above shows both columns and sorts on either.
- What property tax exemptions are available in Colorado?
- The senior exemption removes 50 percent of the first $200,000 of actual value for owners 65 or older on January 1 who have owned and occupied the home for at least ten consecutive years; apply to the county assessor by July 15. Veterans rated 100% permanently disabled and Gold Star spouses get the same exemption, applying by July 1. Owners 65+ and those in active military service may defer taxes, applying between January 1 and April 1. Eligibility and filing are handled by your county assessor, and the exemption you qualify for changes your bill far more than the county you are in — the rates above are county medians and do not account for any exemption.
- How do I appeal a property tax assessment in Colorado?
- Present oral or written objections to the assessor, who must decide and mail a Notice of Determination. If still dissatisfied, appeal to the county board of equalization, which must notify you in writing within five business days of its decision; from there you may appeal to an arbitrator, district court, or the Board of Assessment Appeals within 30 days. The standard protest date is June 8, and counties over 300,000 population use an alternate schedule. Missing the deadline usually means waiting a full year, so check the date on your own assessment notice rather than relying on a general figure.
- When are property taxes due in Colorado?
- Tax bills reflecting the preceding year's taxes are mailed as soon after January 1 as possible. Amounts greater than $25 may be paid in one payment by April 30 or in two equal payments, the first due by the last day of February and the second by June 15. If the tax amount is $25 or less, payment in full is due April 30. If your taxes are paid through a mortgage escrow account, your servicer pays on this schedule on your behalf.
- How is property assessed in Colorado?
- The county assessor discovers, lists, classifies and values all property. Real property is revalued every odd-numbered year and personal property every year. Property is classified by its actual use on January 1. Residential property is valued using only the market approach; for tax years 2025 and 2026 the comparable sales must have occurred between January 1, 2023 and June 30, 2024. Notices of valuation are mailed by May 1. This is why an effective rate computed from market value — as every rate on this page is — will not match the millage rate printed on your bill: the two are applied to different bases.
