Property tax on a Steamboat Springs home is not one calculation. It is two, added together. For tax year 2026, Colorado assesses residential property at 7.05% of actual value for the school district portion of the bill and 6.8% for the local government portion, and the local government portion is calculated only after subtracting the lesser of 10% of actual value or $70,000. Tax year 2026 is billed in January 2027, so a bill that arrived in January 2026 is tax year 2025, which used 7.05% for schools and 6.25% for local government with no value reduction at all. Each assessed value is then multiplied by the certified mill levy for your parcel’s tax area, which is why two houses of identical value in different tax areas owe different amounts.
I get asked for a single percentage, and I understand why. Buyers want one number they can put in a spreadsheet. The honest answer is that Colorado retired the single residential rate in 2025, and almost nothing written about Steamboat property taxes has caught up. Below is the actual mechanism, worked end to end against Routt County’s own certified levies, plus exactly what you need to pull for your own parcel. I am a broker and not a tax adviser, so treat this as an explanation of how the system works and take the specifics of any transaction to a Colorado tax professional.
How is property tax calculated in Colorado?
The Routt County Assessor states the chain in two lines on the front of the county’s annual abstract: market or actual value multiplied by the assessment rate equals assessed value, and assessed value multiplied by the mill levy equals taxes due. A mill is one dollar of revenue for each one thousand dollars of assessed valuation. The assessor’s job is to set the actual value. The taxing authorities set the levies, each certifying its own in December.
The step that trips people up is that since tax year 2025 there are two assessment rates rather than one. The state brochure is explicit: “Beginning in 2025, residential property will have two assessment rates. One assessment rate will be used to calculate local government assessed values and the other rate will calculate school district assessed values.” Routt County says the same thing in plainer language on its abstract: residential property pays on 6.25% of actual value on non-school levies and 7.05% to the school levy for tax year 2025. So your parcel carries two different assessed values on the same bill, and each is multiplied by a different set of levies.
What are the residential assessment rates for 2025 and 2026?
| Tax year | Residential, school levy | Residential, non-school levies | Value reduction | Bill arrives |
|---|---|---|---|---|
| 2025 | 7.05% | 6.25% | None | January 2026 |
| 2026 | 7.05% | 6.8% | Lesser of 10% of actual value or $70,000, non-school side only | January 2027 |
Sources: Colorado Division of Property Taxation, “Understanding Property Taxes in Colorado,” publication 15-DPT-AR PUB B1 (01/26), for the tax year 2026 rates and the value reduction. Routt County Assessor, Abstract of Assessment and Summary of Tax Levies, Tax Year 2025, for the tax year 2025 rates and for the statement that 2025 assessments are payable in 2026.
Read that table before you quote a rate at anyone. If you opened a bill in 2026, you were looking at tax year 2025, a non-school rate of 6.25%, and no value reduction. The 6.8% rate and the $70,000 reduction apply to tax year 2026 and reach your letterbox in January 2027. A great deal of published commentary about Steamboat taxes collapses these two years into one, and that alone accounts for a large share of the wrong numbers in circulation.
A quick way to spot an out of date page
If a page gives you a single flat residential assessment rate of any kind, it predates the two rate structure that began in tax year 2025, which the Colorado Division of Property Taxation sets out in its current brochure. Some official county pages still carry the older single rate example. Check the publication date before you rely on any assessment rate you read, including this one.
What is the value reduction, and does it apply to my home?
For tax year 2026, a portion of actual value is subtracted before the non-school rate is applied. The Eagle County Assessor describes it as an actual value adjustment of “10% of the first $700,000,” and the Boulder County Assessor sets out the order of operations as actual value minus the value reduction equals the reduced value, which is then multiplied by the local government assessment rate. Ten per cent of $700,000 is $70,000, which is why the rule is usually stated as the lesser of 10% of actual value or $70,000.
Two things follow, and both matter in Steamboat. First, the reduction applies only to the non-school side of the bill. The school district side is calculated on full actual value with no subtraction. Second, the reduction is capped in absolute terms, so above $700,000 of actual value it is a flat $70,000 no matter how expensive the property is. The Colorado Association of REALTORS reported a median single-family sale price in Steamboat Springs of $2.095 million for full-year 2025 and $1.619 million in July 2026. A median that far above $700,000 means most single-family sales here clear the threshold and take the flat $70,000, so the relief is worth the same number of dollars on a modest sale as on a very large one, and therefore much more in proportion to a smaller bill.
In assessed value terms, $70,000 of actual value removed at the 6.8% non-school rate is $4,760 of assessed value removed. To turn that into money, multiply $4,760 by your parcel’s total non-school levy and divide by 1,000. That is the whole of it. The reduction is real, and it is smaller than most people expect.
Why do city and county parcels pay different amounts?
Your total levy is the sum of every taxing authority whose boundary contains your parcel, and Routt County publishes exactly that, tax area by tax area, in its annual Abstract of Assessment and Summary of Tax Levies. Fire protection is the clearest divide in this valley.
Inside the city, the City of Steamboat Springs levies its own property tax. The city’s 2026 budget letter states its origin directly: “In 2019, a 2-mill property tax was passed for the City of Steamboat Springs to be dedicated to Fire, EMS operations and capital.” The county’s tax year 2025 abstract shows the City of Steamboat Springs certified at 2.000 mills, matching that dedicated levy. Outside the city, parcels that lie within the roughly 380 square mile service area of the Steamboat Springs Area Fire Protection District are funded through that district instead. Parcels elsewhere in Routt County fall under other fire districts entirely, and the same abstract lists several of them, including North Routt, West Routt, Oak Creek, Yampa and Craig Rural, each with its own levy. Which fire district, if any, applies to a given parcel has to be confirmed parcel by parcel with the assessor.
The district itself is unambiguous about the city boundary. Its published FAQ states that “The 10 square miles of the City of Steamboat Springs is not part of SSAFPD,” and that the district “is funded almost exclusively through property tax revenue” assessed on all taxable property within its service area. The district then pays a share of the cost of Steamboat Springs Fire Rescue, which it puts at roughly 26.5% of that service’s annual budget. So a city parcel and a nearby unincorporated parcel both receive fire service and both pay for it, through different line items at different rates.
Here is what that looks like in certified numbers. Tax area 25 carries the city levy and no fire district levy. Tax area 20 carries the fire district levy and no city levy. Both sit in the Steamboat Springs School District.
| Taxing authority | Tax area 25, mills | Tax area 20, mills |
|---|---|---|
| Routt County government | 13.206 | 13.206 |
| Steamboat Springs School District RE-2 | 13.209 | 13.209 |
| City of Steamboat Springs | 2.000 | Not levied in this tax area |
| Steamboat Springs Area Fire Protection District | Not levied in this tax area | 9.088 |
| Colorado Mountain College | 3.820 | 3.820 |
| East Routt Library District | 2.680 | 2.680 |
| Upper Yampa Water Conservancy District | 1.820 | 1.820 |
| Yampa Valley Housing Authority | 1.000 | 1.000 |
| Colorado River Water Conservation District | 0.502 | 0.502 |
| Steamboat Springs Cemetery District | 0.061 | 0.061 |
| Total certified levy, tax year 2025 | 38.298 | 45.386 |
Source: Routt County Assessor, Abstract of Assessment and Summary of Tax Levies, Tax Year 2025, levies certified in December 2025 for collection in 2026. Tax areas 25 and 20 are two of many in the county. Confirm the tax area for a specific parcel with the Routt County Assessor before relying on these figures.
Two tax areas is not the whole picture, and the spread is the point. Within the Steamboat Springs School District alone, the county’s tax year 2025 abstract shows total certified levies running from 33.478 mills to 102.001 mills depending on the tax area. The top end is driven by metropolitan district levies, for example Overlook Park Metro District at 63.703 mills. Metro districts, water and sanitation subdistricts and general improvement districts are the single biggest cause of one Steamboat property costing far more to hold than a similar one a mile away.
Can you work an example all the way through?
Yes. Take a hypothetical actual value of $2,000,000 in tax area 25 for tax year 2025, the bill that was payable in 2026. Routt County applies 7.05% to the school levy and 6.25% to the non-school levies, so the school side of tax area 25 is the 13.209 mill school district levy and the non-school side is the remaining 25.089 mills.
| Step | School levy side | Non-school levies side |
|---|---|---|
| Actual value, hypothetical | $2,000,000 | $2,000,000 |
| Assessment rate, tax year 2025 | 7.05% | 6.25% |
| Assessed value | $141,000 | $125,000 |
| Certified levy, tax area 25, tax year 2025 | 13.209 mills | 25.089 mills |
| Assessed value multiplied by levy, divided by 1,000 | $1,862.47 | $3,136.13 |
| Total, tax year 2025 | $4,998.60 | |
Method and levies: Routt County Assessor, Abstract of Assessment and Summary of Tax Levies, Tax Year 2025, which states that residential property pays on 6.25% of actual value on non-school levies and 7.05% to the school levy, and that assessed value multiplied by the mill levy equals taxes due. Figures are arithmetic on those certified levies for a hypothetical $2,000,000 actual value in tax area 25. They are not an estimate for any specific property, and they exclude senior and veteran exemptions, any metropolitan district or improvement district levy that does not apply in tax area 25, and the tax increment financing diversion that applies in the urban renewal tax areas at the mountain base.
Run the same arithmetic in tax area 20, where the 9.088 mill fire district levy replaces the 2.000 mill city levy, and the non-school side becomes 32.177 mills. The school side is unchanged at $1,862.47, the non-school side becomes $4,022.13, and the total is $5,884.60. That is $886.00 a year of difference on the same hypothetical value, produced entirely by which districts contain the parcel. For tax year 2026 the arithmetic changes in two places: the non-school rate becomes 6.8%, and the non-school actual value is reduced by up to $70,000 first. The tax year 2026 levies are certified in December 2026 and will appear in next year’s abstract.
Where the certified levies are published
Routt County publishes certified levies for every tax area each year in its Abstract of Assessment and Summary of Tax Levies, archived by year at Prior Year Tax Levies. The county also posts the underlying certification paperwork, including the Tax Authority Abstract Reports and the Mill Levy Public Information Form, at Taxing Authority Valuations. Levies are certified each December, so pull the year you need from the county rather than from any article, including this one.
How do I find the actual mill levy for my parcel?
- Routt County Assessor property search, which carries valuation and classification by parcel: property.spatialest.com/co/routt
- Routt County Treasurer online tax account, which shows the tax actually billed against a parcel: treasurer.co.routt.co.us
- Routt County Assessor’s Office, 522 Lincoln Avenue Suite 10, Steamboat Springs, telephone 970-870-5544, for the tax area and levy detail for a specific parcel
- Routt County Treasurer’s Office, 522 Lincoln Avenue Suite 30, telephone 970-879-0108, for billing and payment questions
When you are looking at a listing, ask for the parcel number and pull the Treasurer’s record for the prior year. That gives you what the property was actually billed rather than an estimate, and it is the single most reliable thing you can do. I do this on every property I write an offer on.
Why does my bill reflect a value from years ago?
Because Colorado revalues real property every odd numbered year and then holds that value for two tax years. The Routt County Assessor gives the current cycle as tax years 2025 and 2026, with an appraisal date of June 30, 2024 and a study period of July 1, 2022 to June 30, 2024. The assessor also states that 2026 is an intervening year, so a value will not change for 2026 unless an unusual condition exists, such as new construction or a change of classification.
Put that together with the billing lag and the distance becomes clear. A bill paid in 2026 is for tax year 2025, and tax year 2025 rests on a value set as of June 30, 2024, using sales that closed before that date. Your assessor is not tracking this month’s market and is not meant to. If prices have moved since mid 2024, your assessment will not reflect that until the next reassessment. This is also why a fresh sale price and an assessed value routinely disagree, and why neither is evidence that the other is wrong.
When are bills due, and when can I appeal?
The Routt County abstract sets out the payment schedule for tax year 2025, payable in 2026: the first half was due 28 February 2026, the second half is due 15 June 2026, and the due date if paying in full was 30 April 2026. The Colorado Division of Property Taxation gives the general rule that bills are mailed as soon after January 1 as possible, that amounts over $25 may be paid in full or in two equal instalments, and that amounts of $25 or less are due in full on the single April date.
On appeals, Notices of Valuation are mailed by May 1 each year. The Routt County Assessor gives the 2026 real property appeal period as May 4 to June 8, 2026, and that period has expired. That is not the end of the road. The assessor states that if you missed the deadline to file an appeal, you may file a petition for abatement or refund of taxes after you receive your tax notice in January. Call the Assessor’s Office on 970-870-5544 for the petition form and the deadline that applies to it, or start from the county’s abatement forms page. If you file a protest in a normal year and disagree with the assessor’s decision, you may appeal to the county board of equalization, and then to an arbitrator, district court, or the Board of Assessment Appeals within 30 days of the date the decision was mailed.
Note that an appeal or an abatement petition challenges the actual value or classification the assessor has placed on your property. It does not challenge the mill levy, which is set by each taxing authority, or the assessment rate, which is set by the state.
Relief programmes worth asking about
Colorado runs several property tax relief programmes, including the Senior Citizen Property Tax Exemption, the Property Tax Exemption for Veterans with a disability, property tax deferral, and a work-off programme. Eligibility rules are specific and I will not summarise them here, because the detail is what decides whether someone qualifies. The Division of Property Taxation publishes brochures on each, and the Routt County Assessor can tell you what applies to your circumstances.
Frequently Asked Questions
What is the residential assessment rate in Colorado for 2026?
For tax year 2026 Colorado uses two residential assessment rates: 7.05% to calculate the school district portion of the bill and 6.8% to calculate the local government portion, according to the Colorado Division of Property Taxation publication 15-DPT-AR PUB B1 (01/26). The local government rate is applied only after subtracting the lesser of 10% of actual value or $70,000. Tax year 2026 is billed in January 2027. The bill received in January 2026 is tax year 2025, which used 7.05% for the school levy and 6.25% for non-school levies with no value reduction, per the Routt County Assessor’s Abstract of Assessment and Summary of Tax Levies for tax year 2025.
How do I calculate property tax on a Steamboat Springs home?
For tax year 2026, which is billed in January 2027, take the actual value from the Routt County Assessor and multiply it by 7.05% to get the school district assessed value. Separately, subtract the lesser of 10% of actual value or $70,000, then multiply the remainder by 6.8% to get the local government assessed value. Multiply each assessed value by the corresponding certified mill levy for your parcel’s tax area and divide by 1,000, then add the two results. Levies are parcel specific and are certified each December, so confirm your tax area with the Routt County Assessor’s Office on 970-870-5544. Tax year 2025, billed in January 2026, used the same method with 7.05% for the school levy, 6.25% for non-school levies, and no value reduction.
What is the total mill levy in Steamboat Springs?
There is no single figure, because the total is the sum of the taxing authorities whose boundaries contain the parcel. For tax year 2025 the Routt County Assessor’s Abstract of Assessment and Summary of Tax Levies shows tax area 25, which carries the City of Steamboat Springs levy, at a total of 38.298 mills, and tax area 20, which carries the Steamboat Springs Area Fire Protection District levy instead, at 45.386 mills. Across all tax areas in the Steamboat Springs School District the same document shows totals ranging from 33.478 to 102.001 mills, with the highest driven by metropolitan district levies. Certified levies are published annually by Routt County at co.routt.co.us under Prior Year Tax Levies.
Why is there a school rate and a local government rate?
Colorado split the residential assessment rate beginning in tax year 2025. As the Colorado Division of Property Taxation states, one rate is used to calculate local government assessed values and the other calculates school district assessed values. The practical consequence is that a single property carries two different assessed values on the same tax bill. For tax year 2026 only the local government side benefits from the value reduction of up to $70,000 of actual value; for tax year 2025 there was no value reduction on either side.
Do homes inside Steamboat Springs city limits pay different property taxes than homes in unincorporated Routt County?
Yes, because the total mill levy is the sum of the taxing authorities whose boundaries contain the parcel. For tax year 2025 the Routt County Assessor certified the City of Steamboat Springs at 2.000 mills, matching the dedicated fire and EMS property tax city voters approved in 2019, and the Steamboat Springs Area Fire Protection District at 9.088 mills. The district’s own FAQ confirms that the 10 square miles of the City of Steamboat Springs is not part of the district, and its service area covers roughly 380 square miles rather than all of unincorporated Routt County. Parcels outside that boundary fall under other fire districts, such as North Routt, West Routt, Oak Creek or Yampa, each with its own levy, so compare parcels rather than areas.
Why does my assessed value not match what I just paid for the house?
Because assessed values are set on a two year cycle with a fixed appraisal date in the past. The Routt County Assessor gives the current cycle as tax years 2025 and 2026, with an appraisal date of June 30, 2024 and a study period of July 1, 2022 to June 30, 2024, and states that 2026 is an intervening year in which values do not change unless an unusual condition exists. A purchase completed after that appraisal date has no effect on the assessment until the next reassessment.
When are Routt County property taxes due?
Bills are mailed as soon after January 1 as possible and cover the preceding tax year. For tax year 2025, payable in 2026, the Routt County Assessor’s abstract gives a first half due date of 28 February 2026, a second half due date of 15 June 2026, and a full payment due date of 30 April 2026. The Colorado Division of Property Taxation adds that amounts of $25 or less are due in full on the single April date. Confirm current year specifics with the Routt County Treasurer’s Office on 970-879-0108.
How do I appeal my Routt County property valuation, and what if I missed the deadline?
Notices of Valuation are mailed by May 1 and the Routt County Assessor gave the 2026 real property appeal period as May 4 to June 8, 2026, which has expired. The assessor states that if you missed the deadline to file an appeal, you may file a petition for abatement or refund of taxes after you receive your tax notice in January. Call the Assessor’s Office on 970-870-5544 for the petition form and its deadline. Where a protest is filed on time and denied, you may appeal to the county board of equalization, and then to an arbitrator, district court, or the Board of Assessment Appeals within 30 days of the date the decision was mailed. An appeal or abatement petition contests the actual value or classification only, not the mill levy or the assessment rate.
Should I rely on this page to budget for a purchase?
Use it to understand the mechanism, not to produce a figure for a specific property. The reliable number is the tax actually billed against that parcel in the prior year, available from the Routt County Treasurer, adjusted for the change in assessment rate and for any levy certified in December. Because tax treatment varies with use, occupancy, short term rental activity and ownership structure, take the specifics of any transaction to a Colorado tax professional or attorney before you rely on them.

Want the real tax figure on a specific property?
Send me the address or the parcel number and I will pull the Treasurer’s billing record and the tax area detail before you write an offer. It takes a few minutes and it is a great deal more useful than an estimate.
