Account and Parcel Search

Weld County Account Number and Parcel Number Lookup

In Weld County, the account number is often the most practical identifier for taxes and assessment records. The Property Portal also supports parcel number search, and the help page says parcel search can use at least the first six digits of the parcel number.

Account
Example R0355194
Parcel
Use at least first 6 digits
Address
Best for homeowners
STR / API
Useful for rural / energy parcels
1

Account number

Use this for direct property identification and tax-record matching.

2

Parcel number

Useful for GIS, legal research, appraisal review and property portal search.

3

Section-township-range

Helpful for rural, agricultural, land and energy-related property searches.

4

API number

Useful when researching oil and gas property records in the county portal.

Best practice: Save both the account number and parcel number once you find the record. Use account number for tax and assessment communication, and use parcel/legal description for maps, deeds, title and protest evidence.

Tax Records

Weld County Property Tax Records — Treasurer Payment Dates, Tax Bill Search and Payment Options

The Weld County Assessor estimates property value. The Weld County Treasurer collects property tax payments. If you need a tax statement, payment status, due date, drop box rule or delinquent interest information, use the Treasurer.

Property tax due dates

For 2026, Weld County lists first half due February 28, second half due June 15, and full payment due April 30. Always verify current dates on the official Treasurer page before paying.

Pay online

Use weldtax.com to search tax accounts and pay. Weld County says e-check is free, while debit and credit card payments include third-party fees.

Pay by mail or office

Mail checks, money orders or cashier’s checks payable to Weld County Treasurer to PO Box 458, Greeley, CO 80632-0458. Office payments are accepted at 1400 N 17th Avenue, Greeley, CO 80631.

Mortgage company warning

Colorado law requires the Treasurer to mail the property tax notice to the owner of record. Weld County says mortgage companies do not receive a copy from the Treasurer, so owners should send a copy to the mortgage company if needed.

Need to pay or check a tax bill? Use the official Weld County Treasurer property tax search and payment page.

Open Tax Search
GIS Map

Weld County GIS Property Map and Mobile Property Viewer

Weld County provides both a Property Portal map search and a mobile-oriented property viewer. These tools are useful for parcel location, nearby parcels, map layers and rural property context.

Use map after a record search

Search by account, owner, address or parcel first, then use map search to confirm the correct parcel and surrounding area.

Helpful for rural and agricultural land

Section-township-range, large tracts, split parcels, farm/ranch properties and subdivision boundaries are often easier to confirm visually.

Useful for energy-related searches

The property portal supports API number search, which can help with oil and gas related property research.

Not a survey

GIS parcel lines are reference data. For boundary disputes, fences, easements, encroachments or mineral-title questions, use recorded documents and professional survey/title help.

Need map view? Open Weld County Property Portal Map Search or the mobile Property Viewer.

Value Protest

Weld County Property Value Protest — May 1 to June 8 Real Property Appeal Window

A Weld County protest challenges the Assessor’s estimate of value or classification, not simply the amount of tax you pay. The Assessor’s page states real property appeals may be filed between May 1 and June 8 under Colorado law.

1

Review the value date first

For values set for 2025 and 2026, Weld County states the estimate of value is as of June 30, 2024. The county can only consider sales and other market information from 2023 and the first six months of 2024 for those values.

2

File between May 1 and June 8

Use the online form, email, fax, mail or an appointment with an appraiser. Late real property appeals cannot be considered, so keep proof of submission.

3

Include required property details

Provide your name, property address or location, account number or parcel number, phone number, and the reason you are appealing the value. Attach the Real Property Questionnaire if useful.

4

Use strong evidence

Helpful evidence can include comparable sales from the allowed time window, incorrect property characteristics, photos, repair estimates, income/expense evidence for commercial property, and sales search results.

5

Know the next appeal step

If you are not satisfied with the Assessor’s Notice of Determination, you may appeal to the Weld County Board of Equalization in writing. Telephone appeals to the Board are not accepted.

Standing rule: Weld County notes that the owner is the person recognized by law to file a protest. If someone other than the owner or authorized agent files, a written letter of agency may be required.

Need protest instructions? Use the official Weld County real property valuation protest page.

Exemptions and Relief

Weld County Senior and Disabled Veteran Property Tax Exemptions

Weld County Treasurer guidance points qualifying senior and disabled veteran homeowners to Assessor-administered exemption programs. The county states these programs can exempt 50% of the first $200,000 of actual value for qualifying applicants.

Senior exemption

For qualifying seniors, the exemption must be applied for and approved by the Assessor’s Office. Application rules and deadlines should be checked through official Weld County and Colorado pages.

Disabled veteran exemption

Qualifying disabled veterans may also be eligible. Documentation and eligibility rules can be specific, so verify through official county and state resources before filing.

Application deadline

Weld County Treasurer guidance lists July 15 as the application deadline for the year in which the exemption is sought. Board of Equalization materials also reference senior exemption appeal timing.

Assessor phone help

For exemption questions, call the Weld County Assessor’s Office at 970-400-3650.

Recorded Documents

Weld County Clerk and Recorder — Deeds, Plats, Liens and Recorded Documents

Use the Clerk and Recorder for recorded documents, not the Assessor property card. The Recording Department processes and preserves documents presented for public record, including real estate records, subdivision maps, marriage licenses and other recorded records.

Recorded documents from 1865 to present

Weld County states recorded documents range from 1865 to the present, and most documents are available electronically.

Self-service search

Troubleshooting

Common Problems When Searching Weld County Property Records

Most search problems come from address formatting, rural parcels, account/parcel confusion, owner-name variations, oil and gas identifiers, or using the Assessor page when the Treasurer or Recorder is needed.

1

Address search gives no result

Use only a portion of the address, such as the house number and street name. Remove city, ZIP, unit, punctuation, direction and suffix. Then try map search.

2

Owner name is hard to find

Try last name only, business-name fragment, trust name, prior owner or spelling variation. For legal title history, search recorded documents.

3

Tax bill does not match value

Assessor value is only part of the tax calculation. Taxing authorities, mill levies, exemptions, payment timing and delinquent interest affect the tax bill.

4

Protest deadline is close

Real property appeals are filed May 1 through June 8. File online, email, fax, mail or appointment as allowed by the county, and keep proof of timely submission.

5

You need a legal deed or lien answer

Use the Clerk and Recorder recorded document search. The property portal is not a legal title opinion and should not be used alone for closing, lien, estate or boundary decisions.
