Gunnison County Property Assessor 2026: Search & Tax Records

Gunnison County Colorado Property & Tax Guide

Search Gunnison County Property Records, 2026 Values, Parcel Maps & Tax Accounts

Gunnison County’s Assessor offers more than one way to research property. The main Property Record Search can locate an account by owner name, address, account number or legal description; the Community Portal adds map-based neighborhood context; and the county’s COMPER tool helps owners identify nearby comparable sales.

The 2026 cycle needs careful date handling. 2026 is Colorado’s intervening assessment year, so most real-property actual values carry forward from the 2025 reappraisal unless the property changed. At the same time, taxes being collected during 2026 are generally the prior tax year’s certified taxes. This guide separates those two timelines so owners can correctly search records, pay delinquent 2025 taxes, review 2026 valuation notices, continue a timely appeal to the County Board of Equalization, and prepare for taxes generated from the 2026 assessment.

Two Different Tax Years Are in Play Right Now

Taxes currently being collected in 2026: Gunnison County tax statements were mailed near the end of January. The regular first-half, full-payment and second-half deadlines have already passed. An unpaid account is now delinquent and requires interest.
2026 property assessment: real-property protests closed June 8. If you filed a timely protest, the Assessor must mail the Notice of Determination by August 17, and the next appeal deadline to the County Board of Equalization is September 15, 2026.
If you did not file a timely May 1–June 8 real-property protest, the September 15 CBOE route is not a replacement for the missed first-level appeal. Gunnison County’s CBOE requires a timely Assessor protest before a CBOE valuation appeal.
If you did protest: watch your mail now. The Assessor’s 2026 Notice of Determination must be mailed by August 17. If you disagree, preserve your CBOE rights by submitting the signed appeal no later than September 15, 2026.

What a Gunnison County Property Record Can Tell You

Property field What it means What to verify
Account Number Assessor account identifier used for property research. Save it for Assessor, comparable-sales and tax work.
Owner Owner reflected in Assessor records. Use the recorded deed when legal ownership or a recent transfer matters.
Property Address Physical situs location. Do not confuse situs with owner mailing address.
Legal Description Recorded-property description used to identify the land. Compare to deed, subdivision plat or survey for legal work.
Land Characteristics Land-use, area and valuation characteristics. Incorrect acreage should be resolved with recorded deed/survey/plat evidence.
Improvement Characteristics Home/building details that influence appraisal. Living area, basement finish, garage/carport, quality, condition and construction details.
Actual Value Colorado’s appraisal value before the statutory assessment-rate calculation. Use the correct appraisal date and sales period.
Assessed Value Tax-base value after applying Colorado’s applicable statutory assessment treatment. 2026 residential calculations can differ between school and non-school levies.
Recent Sales Transfer information available for market research. Not every recorded transfer is a valid arm’s-length comparable.
Tax History Historical property-tax information associated with the account. Use Treasurer search for the current amount due and payment status.
Ownership update timing: Gunnison Assessor staff continually review documents recorded by the Clerk & Recorder and normally aim to update ownership within roughly two weeks, although May can take longer because valuation appeals receive priority.
2026 is an intervening year

How the 2025–2026 Gunnison County Valuation Cycle Works

Jan. 1, 2023 Beginning of the minimum comparable-sales window used for the 2025–2026 reappraisal cycle.
June 30, 2024 Appraisal date and end of the minimum sales data period for 2025–2026 valuations.
2025 Reappraisal Odd-numbered year in which real property was revalued using the new statutory sales study.
2026 Intervening Year Most actual values remain at the 2025 level unless the property changed, such as through new construction.
Why a 2026 sale may not prove your 2026 value is wrong: the county must value 2025–2026 real property using the legally defined appraisal date and applicable sales study. Later market movement generally cannot simply replace that statutory valuation date.
Gunnison typically uses at least 24 months of sales. Colorado law allows the Assessor to extend the study farther back in six-month increments, up to five years before June 30, 2024, when additional comparable data is necessary.
Colorado’s 2026 calculation is not a one-rate system

2026 Residential, Commercial & Agricultural Assessment Treatment

Colorado changed assessment rates and value adjustments through recent legislation. Gunnison County’s current Assessor page highlights the 2026 framework. Residential property can require a different calculation for school-district levies and other local-government levies, so using one generic residential percentage for an entire tax bill can be misleading.

Residential School vs non-school calculations Gunnison publishes statutory branches tied to statewide value growth. Non-school residential treatment for 2026 also incorporates a statutory actual-value reduction before the applicable assessment percentage is applied.
25% 2026 commercial & agricultural The county’s current legislative summary states that commercial property and agricultural property use 25% of actual value for the 2026 property tax year.
26% Most other nonresidential / personal property Gunnison’s current 2026 legislative summary lists 26% for most other nonresidential and personal property.
Do not copy a residential percentage from an old Colorado article. For exact 2026 assessed values, use the current Gunnison property record and the final Colorado assessment rules applicable to that property and taxing authority.
Property tax formula: assessed value × mill levy ÷ 1,000 = tax for that levy. One mill equals $1 of property tax for every $1,000 of assessed value.

For the cleanest estimate, copy the assessed values and applicable mill levies from your current property/tax information rather than guessing a residential assessment percentage.

Enter the assessed values and mill levies shown for the property. This avoids applying an outdated or incorrect Colorado residential assessment rate.

Mill levies vary by parcel. County, school, municipality, fire, sanitation, water, metropolitan and other special districts can overlap differently across Gunnison County.
Three separate research tools

Property Search vs Community Portal vs COMPER Comparable Sales

Community Portal search tip: its map interface supports account number or property address; for address searches it recommends entering street number plus street name, such as “123 Main.”

What makes a stronger comparable sale?

  • Similar economic area or neighborhood
  • Similar living area
  • Similar architectural type
  • Similar construction quality
  • Similar condition
  • Similar land influence
  • Sale inside allowed statutory study period
  • Arm’s-length transaction
For a 2026 CBOE appeal, Gunnison specifically says market evidence must fit the legally allowed valuation period. The county identifies January 1, 2023 through June 30, 2024 as the core market period, with earlier data potentially extending back under statutory rules.
Important current deadline: September 15, 2026

Gunnison County 2026 Property Assessment Appeal Process

NOV Real-property Notice of Valuation by May 1.
Assessor Protest May 1 through June 8.
NOD Assessor determination mailed by Aug. 17.
CBOE Written appeal due Sept. 15.
Further Review BAA, District Court or binding arbitration.
First-level 2026 protest is closed. Real-property protests had to be filed in writing during the May 1–June 8 period. Simply calling the Assessor or scheduling an appraisal discussion did not constitute an appeal.
But the CBOE deadline is still ahead for eligible taxpayers. If you timely protested and disagree with your Assessor’s Notice of Determination, submit the CBOE appeal on or before September 15, 2026.

How to file the 2026 CBOE appeal

Use the Notice of Determination. Complete the back of the NOD mailed after your Assessor-level protest.
State a specific opinion of value. Gunnison’s CBOE requires a dollar amount rather than only saying the Assessor’s figure is too high.
Sign and date the form. An unsigned or incomplete submission can jeopardize the appeal.
Submit by September 15, 2026. Return it in person, by mail or by email to the County Board of Equalization. The county says late submissions are not accepted.
Re-submit your evidence. Evidence from your earlier Assessor protest does not automatically transfer to the CBOE.
Prepare for a 15-minute hearing. Hearings can be in person or by Zoom during the September–November hearing period.
CBOE contact: 200 E Virginia Ave., Gunnison, CO 81230 · 970-641-7600 · cboe@gunnisoncounty.org.
New evidence: if bringing new evidence to the hearing, Gunnison instructs taxpayers to bring three copies—for the Clerk, Hearing Officer and Assessor.
Further appeal: if dissatisfied with the CBOE decision, a taxpayer generally has 30 days to choose the Colorado Board of Assessment Appeals, District Court or binding arbitration. Arbitration is final.

2026 Business Personal Property Records

Gunnison County publishes separate 2026 declaration schedules for general business personal property, residential rental personal property, lessor property, natural resources, renewable energy, oil and gas and other specialized property classes.

Personal Property NOV Personal-property Notices of Valuation are mailed no later than June 15 each year.
2026 protest deadline Written personal-property valuation protests were due June 30, 2026.
CBOE route A taxpayer who timely protested and disagrees with the Assessor’s determination can use the same September 15 CBOE deadline.
Open Assessor Forms Find current 2026 personal-property declaration schedules, appeal forms, agricultural forms, senior/veteran applications and transfer-declaration resources.

Colorado statewide exemption administered locally

Gunnison County Senior Homestead Property-Tax Exemption

Age requirement Qualifying senior must be at least 65 years old on January 1 of the qualifying year.
10-year ownership The applicant generally must have owned the property for at least 10 consecutive years before January 1.
10-year primary residence The property generally must have been the applicant’s primary residence for the same 10-year period.
Benefit: for a qualifying senior, 50% of the first $200,000 of actual value is exempt from taxation, with the state reimbursing the exempted property tax under the program.
2026 regular deadline has passed. Gunnison’s senior exemption application deadline is July 15 of the year for which the exemption is requested.
Moved after previously qualifying? Colorado’s Qualified Senior Primary Residence classification can help certain homeowners who previously received the senior exemption on another Colorado property for a tax year beginning in 2020 or later and lost the ordinary exemption because they changed primary residence. Gunnison provides the current application and instructions on its Senior & Veteran page.
One late-filing opportunity may still matter

Disabled Veteran & Gold Star Surviving-Spouse Exemption

Gunnison administers Colorado’s Disabled Veteran Property Tax Exemption, including eligible surviving spouses and qualifying Gold Star surviving spouses.

Regular 2026 deadline Completed disabled-veteran applications were due to the Assessor by July 1.
Late application window Gunnison says a late application may be accepted through September 1 when the applicant can show good cause for missing July 1.
Expanded eligibility Beginning with tax year 2025, individual unemployability status determined by the U.S. Department of Veterans Affairs can qualify even without a 100% schedular disability rating.
Actionable August 2026 point: if you otherwise qualify but missed July 1, contact the Assessor now about the good-cause late application before September 1.
Submit veteran exemption documents to Gunnison County Assessor, 221 N Wisconsin St., Gunnison, CO 81230 · 970-641-1085.
Recorded documents determine title changes

Search Gunnison County Deeds, Plats, Surveys & Recorded Documents

The Assessor is an office of record for assessment purposes, but ownership changes are made from documents recorded with the Gunnison County Clerk & Recorder. If you need the legal document itself, use the Recording Office rather than relying only on the Assessor’s owner field.

Deeds Ownership conveyances and documents affecting title.
Plats Subdivision, town and other recorded plats.
Surveys Recorded surveys and county surveyor documents.
Other real-estate records Search by legal description, reception number or book and page.
Start with the Assessor property account. Save current owner, account number and legal description.
Open the official Recording Office page. Go to Gunnison County Recording Office.
Choose the county’s Online Records Search. Gunnison directs users to iDoc Market for indexed recorded documents.
Search by name, legal description, Reception Number or Book and Page. Match more than one field when several documents share similar party names.
Compare the legal description. Use the document—not merely an Assessor owner name—to resolve ownership questions.
Record coverage: Gunnison says more than 100 years of documents are indexed online, with online records covering approximately 1900–2025 and additional indexing continuing. In-office real-estate records extend from 1861 to current.
The Clerk & Recorder is not required to perform the document search for you. Have names, legal descriptions, book/page or reception-number information ready.

Free Gunnison County Document Alerts

The Clerk & Recorder offers Fraud / Document Alerts through its recording-system provider. The alert service can notify a registered property owner when a document associated with the monitored name is recorded.

Open the Gunnison Recording Office page. Follow the county’s link to its iDoc Market records system.
Select Document Alerts. Gunnison says to look for the shield icon in the online system.
Create or sign in to an account. Enter the names you want monitored.
Review any alert promptly. An alert lets you inspect whether a newly recorded document is expected or potentially fraudulent.
Alerting itself is free. The recording office notes that viewing document images can require a pass or subscription from the online-records provider.

Recent Purchase, Address Change & Acreage Corrections

Issue What Gunnison says Best next step
Recent deed not reflected Assessor updates rely on recorded documents and normally target roughly a two-week update period. Confirm the deed is recorded before asking Assessor to change ownership.
Need to add/remove a name Ownership cannot be changed simply by asking the Assessor. Record an appropriate deed with Clerk & Recorder.
Mailing address changed Owner must notify Assessor; Assessor will not change it without owner consent. Submit the county’s Change of Address form.
Acreage appears wrong Acreage is determined from recorded deed, certified survey corresponding to a deed or recorded subdivision map. Gather the controlling recorded evidence before requesting correction.
Future 2026 delinquent-tax event

Gunnison County 2026 Tax Lien Sale

October 19, 2026 County says the auction site opens for registration and research around this date.
November 15 Registration closes; the county states there are no exceptions to the registration deadline.
November 16, 2026 Gunnison’s annual internet tax lien sale is scheduled for one day, with bidding from 8:00 a.m. to 5:00 p.m.
A tax lien sale is not a land auction. Gunnison repeatedly warns bidders that buying the tax lien does not transfer possession, use, improvement or access rights to the property.
2026 tax-lien interest rate: the county’s current sale page still lists the 2026 rate as TBD. Do not rely on an older year’s lien interest rate.

Gunnison County Property Assessor Search & Tax Records FAQs

1. How do I search Gunnison County property records?

Use the official Gunnison County Assessor Property Record Search. Individual property records can be found by owner name, property address, account number or legal description. The record can include land and improvement characteristics, recent sales, valuation history and property-tax history.

3. Is 2026 a reappraisal year in Gunnison County?

4. What sales period is used for Gunnison County 2026 real-property values?

For tax years 2025 and 2026, Gunnison County identifies January 1, 2023 through June 30, 2024 as the minimum comparable-sales period. The Assessor can include older sales in six-month increments, up to the statutory maximum period, when more data is needed.

5. Can I still file a first-level 2026 Gunnison County property appeal?

No. The ordinary 2026 real-property protest period ran from May 1 through June 8. Owners who filed a timely protest should receive an Assessor Notice of Determination by August 17 and may appeal that determination to the County Board of Equalization by September 15, 2026.

6. When are Gunnison County property taxes due?

Owners can normally pay in two installments, with the first half due on the last day of February and the second half due June 15, or pay the entire amount by April 30. If a due date falls on a weekend or holiday, Gunnison accepts payment on the following business day without delinquent interest.

7. How do I search Gunnison County property-tax records?

Use the Gunnison County Treasurer Tax Account Search. The system supports property address, owner name and account or parcel number searches. After opening the account, review the current balance, payment status and available tax statements before paying.

8. What is the Gunnison County senior property-tax exemption?

Qualifying seniors generally must be at least 65 on January 1 and must have owned and occupied the property as their primary residence for at least 10 consecutive years. For qualified applicants, 50% of the first $200,000 of actual value is exempted. The regular application deadline is July 15.

9. Can a disabled veteran still file late for the 2026 exemption?

Possibly. Gunnison’s regular Disabled Veteran Exemption deadline was July 1, but the county says late applications may be accepted through September 1 when the applicant can show good cause for missing the regular deadline.

County Property Search, Homestead & Tax Help Toolkit

Use this free helper to find the right county office, prepare a property search, understand appraised value, review homestead exemption steps, and organize TRIM notice or tax bill questions before using official county websites.

Built for Florida county property guides
Helps users find official resources
No fake database or approval claim
Useful after every article

Find the Correct County Office

Property Appraiser, Tax Collector, Clerk, GIS, and VAB offices do different jobs. Pick your task below.

Quick rule: Property Appraiser = value, records, parcel details, exemptions. Tax Collector = bill and payment. Clerk/Recorder = deeds and recorded documents. VAB = formal value disputes.

Official Property Search Helper

Use this when a county article tells you to search by owner, address, parcel number, folio, PCN, STRAP, or alternate key.

Search tip: If address search fails, try only the house number and main street name. Avoid typing Street, Avenue, Road, Drive, unit numbers, or punctuation unless the official portal requires it.

Homestead Exemption Readiness Check

This helps homeowners prepare before filing through the official county Property Appraiser website.

Important: This is not an eligibility decision. The official county Property Appraiser decides approval, required documents, late filing options, and exemption status.

TRIM Notice & Value Review Helper

Use this to organize your questions before calling the Property Appraiser or preparing an appeal.

Your preparation checklist

Value term Simple meaning
Market value The appraiser’s estimate of the property’s value as of the assessment date.
Assessed value The value after limits or caps may be applied.
Exemptions Approved reductions such as homestead or other exemptions.
Taxable value The value used by taxing authorities after exemptions.

Property Tax Bill Direction Helper

The Property Appraiser values property, but the Tax Collector usually handles the actual bill and payment.

Florida timing reminder: Many Florida tax bills are mailed around November and become delinquent if unpaid after March 31. Always verify exact dates, discounts, and payment fees with the official county Tax Collector.
