Search or Pay Starr County Property Taxes

This page helps you handle Property Tax tasks in Starr County, Texas, including looking up a property, finding tax-related details, and knowing which local office handles the next step.

For most searches, the main tools are the Starr CAD property search and the Starr County Tax Office search. If you need exemptions, protests, or office help, the Starr Central Appraisal District and the Starr County Tax Assessor-Collector are the main public contacts.

Starr CAD Property Search

The Starr CAD search is the main place to look up a property record in Starr County. It supports owner, address, property ID, geographic ID, owner ID, subdivision, neighborhood, abstract, condo, and tax year searches.

• Owner name
• Street number or street name
• Property ID, owner ID, or geographic ID
• Subdivision, neighborhood, abstract, or condo name
• Tax year

If you already know a parcel or account detail, searching by an ID usually narrows results faster than a broad name search.

• Open the search tool for Starr CAD records.
• Choose the search field that best matches what you have, such as owner name, street name, or property ID.
• Keep the search simple if you get too many or too few results. The site suggests using only a first or last name, or only the street name.
• Review the property details carefully. The site states that 2026 values are preliminary and subject to change before certification.

Important: The appraisal district search is for research use. Legal descriptions, acreage, and similar details should be verified before using them for legal purposes or documents.

Starr County Tax Office Search

If you need the county tax office side of the process, use the tax office search page for Starr County. This is the most direct county tax office online path for checking a tax account before you contact staff or make a payment decision.

You can start with the Starr County Tax Office search. For general Texas payment rules, the state says property tax bills usually mail in October, payment is due upon receipt, and taxes are delinquent in most cases on Feb. 1 if unpaid after Jan. 31.

Exemptions and protest options

For exemptions, applications are filed with the appraisal district in the county where the property is located. Texas lists a general deadline of before May 1 for most exemption applications.

Texas also gives property owners the right to protest an appraised value or certain appraisal district actions. In most cases, the protest deadline is May 15 or 30 days after the notice of appraised value is mailed, whichever is later.

You can review state exemption rules at Texas property tax exemptions and protest rules at Texas appraisal protests and appeals. Starr CAD also directs taxpayers to its online appeal portal through the taxpayer portal.

Map and office support for harder cases

If a regular search is not enough, Starr CAD also offers an interactive map and a taxpayer appeal path. The map can help when you need parcel context, boundaries, streets, subdivisions, schools, or flood hazard layers tied to a property search.

For tax collection office and appraisal district support, the public-facing CAD contact pages route users to office staff and a contact form. Those options are useful when a record is unclear, a search result needs verification, or you need help tied to a specific property ID.
