Weld County Property Assessor 2026: Search & Tax Records

by
Weld County Colorado Property Records Navigator

Search Weld County Property Values, Parcel Records, Appeals and Tax Bills

The Weld County Assessor discovers, classifies and values real estate, business personal property, agricultural land, manufactured homes, oil and gas interests and other taxable property. The Treasurer collects the resulting taxes, the County Board of Equalization hears the next assessment-appeal level, and the Clerk and Recorder maintains deeds, plats, liens, mortgages and other recorded property documents.

This 2026 guide explains how to search by owner, address, account number, parcel number, subdivision, section-township-range or API number; read valuation and tax-district fields; find comparable sales; understand the June 30, 2024 appraisal date used for 2025 and 2026 values; appeal a Notice of Determination; check senior and veteran exemptions; pay taxes; and search deeds or tax-lien information.

Weld County Assessment and Tax Status on August 6, 2026

The first Assessor appeal stage has closed, but important second-level deadlines remain. Real-property protests ran from May 1 through June 8, and business personal property, oil and gas and producing-mine protests ran from June 15 through June 30. The Assessor must mail Notices of Determination by August 15, after which qualifying owners can appeal to the County Board of Equalization by September 15.
Watch for the Notice of Determination Owners who filed a timely Assessor protest should review the Assessor’s written decision immediately after it arrives.
Senior exemption appeal The County Board of Equalization lists August 15, 2026 as the senior-property-tax-exemption appeal deadline.
CBOE valuation appeal A dissatisfied owner must file a written CBOE appeal by the deadline. Telephone appeals are not accepted.
Tax lien sale Weld County’s next annual online tax-lien sale is scheduled for November 5, 2026.
Past-due 2025 taxes The 2025 taxes collected during 2026 should now be checked through the Treasurer’s live account for interest or lien status.
No ordinary late Assessor appeals: Weld County states that late real-property and personal-property protests cannot be considered. A Special Notice of Value carries its own 30-day appeal period.
Tax-year distinction: Property taxes are collected one year in arrears. Taxes paid during 2026 generally relate to the 2025 tax year, while the Assessor’s 2026 value will affect the tax bill collected in 2027.

Four Weld County Offices Handle Different Property Tasks

County Assessor

  • Actual and assessed value
  • Classification and characteristics
  • Owner and mailing information
  • Comparable sales
  • Notices of Value
  • First-level protests

County Treasurer

  • Current tax bills
  • Half and full payments
  • Payment receipts and history
  • Delinquent balances
  • Tax-lien sale and redemption
  • Certificates of Taxes Due

Board of Equalization

  • Appeals from Assessor decisions
  • Written CBOE petitions
  • September 15 deadline

Clerk and Recorder

Colorado and Iowa use different systems: Weld County uses a county Assessor, Treasurer, Board of Equalization and Recorder. Iowa can split assessment authority between a county and a city assessor. Compare the structures in this existing Linn County Iowa Assessor property-search guide.

Colorado biennial value cycle

How Weld County’s 2025 and 2026 Property Values Work

The same June 30, 2024 appraisal date supports the 2025 and 2026 valuation cycle. The property’s physical condition, use and level of completion are considered as of the January 1 assessment date for the individual tax year.

Data period begins Qualifying sales and market evidence begin January 1, 2023.
Appraisal date The Assessor estimates value as of June 30, 2024.
2025 condition date Property condition and completion are reviewed for the 2025 assessment.
2026 condition date New construction, demolition, use and classification changes can affect 2026.
2026 taxes collected Taxes based on the 2026 assessment are generally collected during 2027.
Why the 2026 value can change: Although the appraisal date remains June 30, 2024, the Assessor can account for new construction, demolition, property division, combination, classification, exemption or other January 1 changes.
Oil, gas and business property: These accounts can follow specialized declaration, production, classification and protest rules. Use the account-specific notice and Assessor instructions.

Second assessment-appeal level

How to Appeal a Notice of Determination to the CBOE

An owner must first have filed a timely protest with the Assessor and received a Notice of Determination. A CBOE petition is an appeal from that decision—not a replacement for the missed first-level protest.

Read the Notice of Determination immediately. Compare the Assessor’s final value with the requested value and review the stated next steps.
Calendar September 15, 2026. The written appeal must be received, postmarked or electronically date-stamped by the deadline.
Prepare the signed Notice of Determination. Include the signed and dated NOD or a complete signed letter containing the required account and contact information.
State the reason for continuing the appeal. Explain why the Assessor’s determination remains incorrect and identify the requested value.
Use qualifying market evidence. The CBOE applies the same June 30, 2024 appraisal date and 2023–June 2024 evidence period for 2025 and 2026 values.
Choose a written filing method. File online when available or submit by mail, hand delivery, fax or email.
Do not attempt a telephone appeal. The CBOE explicitly requires all appeals to be in writing.
Retain filing proof. Save the portal confirmation, sent email, fax confirmation, county receipt or proof of mailing.
CBOE Instructions Review the current filing methods, deadlines and required information. Email the CBOE Attach the signed NOD or signed appeal letter and all evidence. CBOE Information Line Call 970-400-3650 for procedural questions, not to submit a telephone appeal.
No late CBOE appeals: Weld County states that a late appeal cannot be considered. Mailed filers should retain proof of mailing.
Special Notice of Value: When the Assessor issues a Special Notice, the property owner generally has 30 days from the date printed at the top of that notice to protest.
Senior, veteran, spouse and deferral programs

Weld County Property-Tax Exemptions and Relief

Senior Property Tax Exemption Exempts 50% of the first $200,000 of actual value for qualifying long-term senior owner-occupants. Application deadline: July 15
Portable Senior Classification Temporary 2025–2026 classification for qualifying seniors who lost a prior Colorado senior exemption after moving. Application deadline: March 15
Disabled Veteran Exemption Exempts 50% of the first $200,000 for a qualifying 100% permanently disabled veteran or veteran with individual unemployability. Application deadline: July 1
Gold Star Spouse Exemption Relief may apply to an eligible unremarried surviving spouse whose qualifying spouse died in the line of duty or from service-related injury. Primary residence required
Surviving Spouse Continuation A surviving spouse may continue a previously approved senior or disabled-veteran exemption when statutory requirements are satisfied. Use the correct long form
Property-Tax Deferral Qualifying seniors and active military service members may defer taxes through a state-administered simple-interest loan program. Deferral is not forgiveness
Property Tax, Rent and Heat Rebate Colorado’s PTC program may help qualifying low-income seniors, surviving spouses and disabled residents. State income-based program
Charitable Organization Exemption Qualifying schools, churches and charitable organizations use specialized ownership, use and filing rules. Separate exemption process
Tax Abatement An abatement may correct taxes levied illegally or erroneously because of valuation, levy irregularity, clerical error or overvaluation. Not a routine late protest
2026 filing position: The March 15 portable-senior, July 1 disabled-veteran and July 15 senior application dates have passed. The CBOE lists August 15, 2026 as the senior-exemption appeal deadline.
Senior ownership and occupancy test: A regular applicant generally must be at least 65 on January 1 and must have owned and occupied the home as the primary residence for at least 10 consecutive years before January 1.
Apply once when approved: The senior and disabled-veteran exemptions generally continue in later years while qualifying ownership and occupancy remain unchanged.
Tax deferral creates a loan: Deferred taxes remain secured and accrue simple interest. Review repayment events and lien consequences before choosing deferral.
Senior Exemption and Classification Review ownership, occupancy, age, surviving-spouse and portable-senior rules. Disabled Veteran and Spouse Relief Check disability, discharge, primary-residence and spouse requirements. Assessor Forms Find exemption, abatement, address, agricultural, ownership and personal-property forms.
Treasurer records and payment history

How to Find a Weld County Property-Tax Bill

Open the official Treasurer tax portal. Use Weld County Tax Information.
Search the account. Use the property owner’s last name or business name, then narrow the results using account, parcel or address information.
Open the correct tax account. Match owner, account number, parcel, location, tax year and taxing area.
Review whether taxes were paid in halves or in full. Confirm each installment, payment date, payer and remaining balance.
Print prior receipts when needed. Use the Treasurer system to verify whether a payment posted and to obtain prior-year payment evidence.
Review delinquent interest and lien status. A balance after the statutory deadline can include monthly interest, fees or tax-lien-sale consequences.
Compare escrow activity. Check the Treasurer record against mortgage-company disbursement records before paying twice.
Save the tax account before and after payment. Retain the account number, tax year, amount, confirmation and bank evidence together.
Tax statement Treasurer issues the annual bill for the prior tax year.
First-half payment Owners using installments pay the first half by the statutory February deadline.
Full-payment option Owners paying the annual bill in one payment use the April 30 deadline.
Second-half payment The remaining installment is due June 15.
2026 tax-lien sale Qualifying unpaid real-property taxes can proceed toward the annual sale.
Do not combine payment schedules: An owner should either pay in two statutory installments or pay the entire annual amount by the full-payment deadline. Confirm the live account when any deadline has passed.
Weekend and holiday rule: Colorado provides next-business-day treatment when a statutory filing or payment date falls on a Saturday, Sunday or legal holiday. Verify the Treasurer’s current instructions for the exact year.
Online, mail or office payment

How to Pay Weld County Property Taxes

Online bank payment Search the exact account, select the correct tax year and review the payment processor’s total before authorizing. Save transaction confirmation
Credit or debit card Card processing fees can apply and should be displayed before final submission. Verify processor charge
Payment by mail Include the tax coupon or account details and use the Treasurer’s current mailing address and postmark rules. Retain mailing evidence

Mortgage escrow Confirm the lender’s tax disbursement in the Treasurer portal before sending an owner payment. Avoid duplicate payment

Tax-lien redemption is different: Redemption amounts change monthly and must be paid with accepted certified funds. Ordinary postmarks are not accepted for a redemption deadline.
“I am checking Weld County account __________ for tax year __________. Please confirm whether the account was paid in halves or in full, the current amount due, monthly interest, lien status and the accepted payment method.”
Annual delinquent real-estate tax process

Weld County Tax Lien Sale and Redemption

Weld County’s next online tax-lien sale is scheduled for November 5, 2026. The sale transfers a tax-lien certificate to an investor; it does not immediately transfer ownership of the property.

Taxes become delinquent Interest and collection costs begin after payment deadlines.
Potential-sale list A changing list is published before the annual auction.
Tax lien is sold An investor purchases the tax-lien certificate at the online sale.
Owner may redeem The owner or qualifying interest holder pays taxes, interest and costs to the Treasurer.
Later deed process A certificate holder may pursue a public Treasurer’s Deed process only after statutory conditions are met.
Sale of the tax lien is not sale of the home: The investor acquires a lien certificate. The property owner retains redemption rights until the later statutory process reaches a point at which redemption ends.
2026 certificate expiration: Weld County states that tax-lien certificates issued after January 1, 2026 expire after seven years.
Redemption payment: The Treasurer requires cash or certified funds for real-property tax-lien redemption. The amount changes monthly because interest is calculated by month.
Tax Lien Sale Information Review auction, redemption, certificate, endorsement and Treasurer’s Deed guidance. Call the Treasurer Contact 970-400-3290 for a current payoff or redemption amount.
Recorded documents control ownership updates

How to Update Ownership on a Weld County Property Account

Prepare ownership document Use a deed, manufactured-home title, court order, death certificate or other qualifying instrument.
Include required elements A deed needs grantor, grantee, conveyance language, legal description, signature and notarization.
Record with the Clerk The Assessor recognizes ownership changes from properly recorded documents.
Submit transfer declaration A TD1000 may be required when the conveyance is subject to a documentary fee.
Verify account update Reopen the Property Portal and check owners, mailing address and deed references.
Transfer Declaration penalty: When a required Real Property Transfer Declaration is not returned to the Assessor, a penalty may be imposed of $25 or 0.025% of the sale price, whichever is greater, for qualifying years until the property is sold.
Mailing-address importance: Colorado deeds must contain a valid grantee mailing address. The address is used to determine where future tax statements should be mailed.
Several documents may be needed: Estates, trusts, deaths, court actions, manufactured homes and complex transfers can require more than one recorded document.
Recorded documents from 1865 to present

How to Search Weld County Deeds, Mortgages, Plats and Liens

Open the Recorder self-service search. Use the official Weld County recorded-document system.
Acknowledge the search disclaimer. The index is a guide to recorded documents and should be checked using several search variations.
Search current and prior owner names. Try grantor, grantee, trust, company, estate, alternate spelling and former-owner names.
Use document details when available. Search by recording number, document type, recording date or party name.
Open the correct index result. Compare grantor, grantee, recording date, legal description, document type and related account information.
Search connected instruments. Pair the deed search with deed-of-trust, release, assignment, lien, easement, plat and corrective-document searches.
Purchase the image or copy when needed. Index viewing can be free, while document images and printed copies may require payment.
Request certification when required. A court, lender, title company or government agency may require a certified rather than plain copy.
Recording service Published fee Important requirement
Letter or legal-size document $43 regardless of page count Verify current statutory fee before submitting.
Map or plat $43 regardless of page count Mylar and dimension requirements apply.
State documentary fee $0.01 per $100 Applies to qualifying conveyances over $500.

Electronic real-estate UCC $8 Use an accepted electronic-recording route.
Military discharge No charge Access restrictions and identification rules apply.
Recording does not guarantee validity: The Clerk records documents presented in recordable form but does not determine whether the instrument is legally effective or authentic.
Only the Greeley office records documents: Documents can be submitted in person, by mail or through approved eRecording providers.
Title-search warning: A self-service index search is not a guaranteed title examination. Professional review may need deeds, deeds of trust, judgments, probate matters, tax liens, easements, mineral interests and other instruments.

Title-specific answers

Weld County Assessor Property Search FAQs

1. How do I search Weld County property assessor records?

Use the official Weld County Property Portal and search by account number, owner name, address, subdivision, parcel number, section-township-range or API number. Open the correct result and verify the account, parcel, address, owner, classification and tax district.

2. What information appears in a Weld County property record?

The portal can display owner information, actual and assessed values, building details, land information, tax districts, mill levies, estimated future taxes, recorded deeds, Notices of Valuation, comparable sales and links to tax-payment information.

3. What appraisal date is used for Weld County 2025 and 2026 values?

Weld County uses a June 30, 2024 appraisal date for values set for 2025 and 2026. The Assessor can consider qualifying sales and market information from January 1, 2023 through June 30, 2024. Property condition and completion are considered as of January 1 of the assessment year.

4. What was the 2026 Weld County real-property protest deadline?

The regular real-property protest period ran from May 1 through June 8, 2026. Weld County states that late ordinary appeals cannot be accepted. A Special Notice of Value generally provides a separate 30-day appeal period.

5. What is the 2026 Weld County Board of Equalization deadline?

An owner who filed a timely Assessor protest and received a Notice of Determination can appeal to the County Board of Equalization. The 2026 appeal must be received, postmarked or electronically date-stamped by September 15.

6. How is Weld County property tax calculated?

The Assessor determines actual value. Actual value is multiplied by the applicable assessment rate to produce assessed value. Assessed value is then multiplied by the combined mill levy of the property’s taxing districts to estimate the property tax.

7. What is the Weld County senior property-tax exemption?

A qualifying senior can receive an exemption equal to 50% of the first $200,000 of actual value. A regular applicant generally must be at least 65 on January 1 and must have owned and occupied the property as the primary residence for at least 10 consecutive years. The regular application deadline is July 15.

8. When are Weld County property taxes due?

Owners can generally pay in two installments, with the first half due at the end of February and the second half due June 15, or pay the full annual amount by April 30. Weekend and holiday rules may move a statutory deadline to the next business day.

9. What happens when Weld County property taxes are sold at tax lien sale?

An investor purchases a tax-lien certificate, not immediate ownership of the property. The owner or another qualifying interest holder can redeem by paying the Treasurer the delinquent taxes, interest and costs before the later Treasurer’s Deed process reaches the applicable cutoff.

10. Where can I find Weld County deeds and property liens?

Use the Weld County Clerk and Recorder self-service search. Search by grantor, grantee, document number, document type or recording date. The index can be viewed online, while document images, copies or certifications may require payment.

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.
