Costilla County, Colorado

Where to obtain records

Costilla County Treasurer / Property Tax Records

How to find the information

The current Treasurer/Public Trustee page lists the Treasurer contact and a separate 2026 tax-lien-sale flyer and Tax Lien Sale Information route. Ask the Treasurer for the existing unpaid real-property ledger, delinquency report or dated redemption amount, specifying the account and tax years.

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 Costilla 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.
