Boulder County, Colorado

Where to obtain records

Boulder County Treasurer / Property Tax Records

How to find the information

Treasurer states that online payments are disabled for the remainder of the year while tax account information and receipt copies remain viewable. Use the county-linked tax-account service or call 303-441-3520 for existing unpaid history and a dated amount.

For an existing delinquent real-property report, parcel account/payment ledger, Statement of Taxes Due or dated tax-lien redemption amount, provide the account/parcel/schedule reference, tax years and desired as-of date. Ask whether current delinquency, sold or county-held liens, later endorsements, interest and advertising/redemption costs are included and whether recent payments have posted. Confirm inspection, electronic-copy, certification, research and extract fees. Assessor valuations, loan foreclosures and dated sale lists do not certify today’s unpaid balance.

What to ask for

“I am looking for publicly available delinquent real-property tax records for Boulder County for [tax year]. Which office maintains these records? Is there an online search or downloadable list? If not, how can I request a copy, and what fees apply?”

Have the property address, parcel number, owner name, and tax year ready when searching for a particular property.

County-specific notes

The published payment restriction is a review-time notice. Generic search-help text includes conflicting owner-search wording, so use an account/parcel reference when possible. No taxpayer query, portal result or electronic payment was tested. No taxpayer query, account registration, CAPTCHA completion, public-records request, bidder registration, upload or payment was submitted. No taxpayer rows or owner-list attachments are included.
