Collin County, Texas
Where to look, which office to contact, and how to request records.
Where to obtain records
Collin County Tax Assessor-Collector
Official published tax-record access guidanceHow to find the information
The county separates a full current-and-delinquent Tax Roll from a delinquent roll covering 20 years. The files include real, business-personal and personal property: isolate real property for this directory’s purpose. Fixed-width ASCII layouts are provided; files are created Saturday and posted Monday except holidays, without technical support. The endorsed account service offers account number, owner name/address or property location and paid/unpaid options.
Identify the real-property account/parcel, taxing units, tax years and desired as-of date. Request the existing unpaid collection ledger or dated statement, not an appraisal-value report. Ask which levies, payments, penalty/interest and attorney costs are included. Dated foreclosure/resale lists, court files, post-sale redemption calculations and excess-proceeds records are separate: ask the collector to identify the relevant sheriff/constable, district clerk or other custodian. Do not assume a sale list contains all delinquent accounts or all amounts needed to redeem. Ask about existing electronic records, inspection and published copy/certification prices before ordering; a custom extract is not promised.
What to ask for
“I am looking for publicly available delinquent real-property tax records for Collin 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.
