Search Starr County Property Tax
Property owners in Starr County begin every tax question with a public records search through the Starr County Tax Assessor-Collector office. The office maintains the master tax roll, records ownership transfers, applies exemptions, and bills each parcel every October. Searching starts by gathering the property’s account number from a prior tax statement, the deed recording number from the County Clerk, or the street address of the home or land.
Each parcel carries a unique account ID assigned by the assessor at the time of plat recording. With that ID, an owner pulls the current appraised value, certified values from prior years, exemption status, and any pending protest notes. The search shows tax sale flags when a previous year’s bill entered delinquency and lists the cumulative penalty plus interest accrued on that bill.
New owners who never received a paper bill still pull the record by name or address. Public terminal access at the courthouse provides the same dataset during regular business hours. For remote users, the Starr County Tax Office online portal at https://starr.go2gov.net mirrors those records and the Taxpayer Portal at https://portal.starrcad.org/ provides access to property details, exemptions, and documents.

Starr County Appraisal District Records and Roles
The Starr County Appraisal District (SCAD) appraises every parcel each year for ad valorem taxation. The district operates separately from the Tax Assessor-Collector and reports to a board of directors appointed by local taxing units. Its duty covers equity across neighborhoods, correct exemption tracking, and timely delivery of the Notice of Appraised Value each spring.
The appraisal district’s property search portal lets users view certified values, land size, improvement sketches, and sales history. Each parcel record includes a protest deadline tied to the mailing date of the Notice of Appraised Value. Owners reviewing their notice for the first time compare the certified value to recent purchase prices to spot overvaluation. Property searches are available free at starrcad.org.
The appraisal district handles exemption applications on the residential side, including homestead, over-65, disability, and veteran categories. Agricultural and open-space applications also pass through the appraisal district, with productivity valuations computed from typical ranching income. Business personal property renditions for oilfield equipment, inventory, and vehicles follow a separate deadline each April.
Key Appraisal District Functions
| Function | Description | Owner Action Point |
|---|---|---|
| Annual valuation | Assigns market value to land and improvements | Review Notice of Appraised Value each May |
| Exemption administration | Files homestead, senior, and veteran exemptions | Submit homestead exemption forms by April 30, 2026 |
| Agricultural valuation | Applies productivity-based land values | Provide use records and stock counts |
| Business personal property | Tracks movable assets for taxation | File rendition each April |
Reading the Tax Bill Line by Line
Starr Property Tax bills arrive in October and list each taxing unit that levies on the parcel. The first line shows the appraised value from the appraisal district, followed by any exemptions that reduce taxable value. After exemptions, the bill applies each entity’s adopted rate to the taxable value, then sums the levies into one total due.
The largest line item on most bills belongs to the local school district. County operations, the farm-to-market road fund, and any municipal or water district levies follow. Special districts, junior college districts, and the Starr County Hospital District add smaller levies based on the parcel’s location within their boundaries.
Sample Tax Bill Components
| Line Item | Typical Source | Where to Verify |
|---|---|---|
| Appraised Value | Starr County Appraisal District | Appraisal district property search at starrcad.org |
| Homestead Exemption | School district + optional county | Tax Assessor-Collector record |
| School District Levy | ISD adopted rate | County adopted rate notice |
| County General Fund | Commissioners Court | Adopted budget document |
| Special District | Water, hospital, or college district | Entity board minutes |
| Total Due | Sum of all entity levies | Bottom of October statement |
Filing a Homestead Exemption
The Starr County homestead exemption lowers the taxable value of an owner’s primary residence. Texas law requires the property to be owned and occupied on January 1 of the tax year. Filing happens at the appraisal district with a signed application, a copy of the deed, and a government-issued ID showing the home address. The deadline to apply for homestead exemption in 2026 is April 30, 2026.
Once approved, the exemption stays on the parcel until ownership transfers or use changes. New owners must file the application themselves, as the appraisal district never auto-transfers a prior owner’s exemption. A late filing between May 1 and the following April 30 applies to the next tax year rather than the current one.
Documents Needed for a Homestead Filing
- Completed homestead application form from the appraisal district
- Recorded deed showing ownership of the property
- Driver license or state ID matching the property address
- Vehicle registration matching the property address, when applicable
- Proof of occupancy such as a utility bill or voter registration
Senior, Veteran, and Disability Exemptions
Property tax exemptions for seniors in Starr County lower the school district levy on the homestead of qualifying owners age 65 or older. Applicants add a date-of-birth proof to the standard homestead package. Once granted, the exemption also triggers a ceiling that caps future school taxes at the first qualifying year’s amount, creating long-term savings.
Disabled veterans receive an exemption tiered by disability rating, ranging from a fixed dollar amount to a full homestead waiver for 100 percent disability. The veteran files a copy of the VA rating letter with the application. Surviving spouses of fallen service members often qualify for the same protection and need a death certificate plus marriage record.
Disability exemptions apply to homeowners with a documented inability to engage in gainful work. The Social Security disability determination letter or a physician’s certification accompanies the filing. Each of these exemptions stacks with the standard homestead, producing layered savings on the tax bill.
Exemption Categories and Owner Requirements
| Exemption | Eligibility | Documentation |
|---|---|---|
| Homestead | Owner-occupied primary residence | Deed and government ID |
| Over-65 | Age 65 or older on January 1 | Birth certificate or passport |
| Disabled Veteran | VA-rated disability | VA rating letter |
| Disability | Unable to engage in gainful work | SSDI or physician letter |
| Surviving Spouse | Spouse of fallen service member | Death and marriage records |
Agricultural and Open-Space Land Use Qualification
The criteria for agricultural exemption in Starr County focus on land used primarily for farming or ranching. Productivity valuation replaces market value, often producing a fraction of the standard tax bill. Parcels typically need a history of agricultural use to qualify, with a minimum of 10 acres often required in Starr County for ag exemption.
Typical qualifying uses include cattle grazing, hay production, irrigated cropland, and wildlife management. Owners file the ag application with the appraisal district and supply stocking rates, harvest records, or lease agreements. Once granted, a rollback penalty applies if the land shifts to non-agricultural use, recovering the tax savings.
Open-space valuation covers smaller parcels dedicated to parks or recreational use, with similar productivity-based formulas. Both programs require the owner to maintain records showing continuous qualifying activity. The appraisal district may request documentation at any time to confirm the land still meets the standard.
Common Records for Agricultural Qualification
- Stocking rate documentation with head counts by pasture
- Hay harvest records showing bales per cutting
- USDA Farm Service Agency acreage reports
- Lease agreements with grazing operators
- Wildlife management plan with annual reports

For owners searching the master roll, the Starr County Tax Assessor-Collector portal at https://starr.go2gov.net provides access to account ledgers.

Payment Deadlines and Penalty Schedule
Property tax due dates for Starr residents fall after the October billing. Bills paid by the statutory deadline avoid penalty and interest. Payments postmarked by the deadline count as timely even if the office receives them a few days later, but online payments must clear by the cutoff hour to qualify.
Late payments trigger a cumulative penalty plus interest each month the bill stays open. Penalty and interest schedules are set by Texas statute and apply uniformly across the county. After several months of non-payment, the account moves toward delinquent tax sale status with additional collection fees. Refer to the Starr County Tax Office or the Texas Property Tax Code for the exact penalty and interest percentages that apply.
Penalty and Interest Accumulation
| Period After Due Date | Penalty | Interest |
|---|---|---|
| February | Per Texas Property Tax Code | Per Texas Property Tax Code |
| March | Per Texas Property Tax Code | Per Texas Property Tax Code |
| April through July | Additional amount per Texas statute | Continued monthly accrual |
| After July 1 | Statutory maximum reached | Continued monthly accrual |
How to Protest a Property Valuation
The steps to appeal property valuation in Starr County begin when an owner disagrees with the certified appraised value. The Notice of Appraised Value arrives by May 15, or 30 days later for some late filings, and includes a protest deadline. For 2026, owners must protest by May 15, 2026 or 30 days after the Notice of Appraised Value is mailed, whichever is later. Owners file a written protest with the appraisal district by the deadline, citing the grounds for disagreement.
Common protest grounds include unequal appraisal compared to similar parcels, overvaluation relative to recent sales, and errors in property characteristics. The protest proceeds to an informal meeting with an appraiser, and unresolved cases move to a formal hearing before the Appraisal Review Board (ARB). Both virtual and in-person hearings are available through the Taxpayer Portal at https://portal.starrcad.org/.
Evidence strengthens a protest. Owners submit a sales comparison analysis, photographs of condition issues, and a list of comparable parcels with lower values. A successful protest adjusts the certified value, lowering the tax bill.
Protest Filing Checklist
- Notice of Appraised Value with parcel ID and account number
- Written protest form with selected grounds
- Comparable sales printout or broker opinion of value
- Photographs documenting condition, defects, or flood damage
- Deadline confirmation from the appraisal district
Delinquent Taxes, Liens, and Tax Sale Auctions
The Starr County tax lien process begins when a bill stays unpaid past the statutory delinquent date. The Tax Assessor-Collector compiles a delinquent roll and prepares for the annual tax sale. Each delinquent parcel receives a judgment that becomes a lien on the property, attaching to the title until paid.
Tax sale auction dates are published in the local newspaper and on the county website ahead of the event. Bidding opens at the courthouse on the scheduled date with registered bidders placing minimum bids tied to the delinquent amount. Winning bidders receive a tax sale deed after the statutory redemption window passes without payment. Refer to the Starr County Tax Office for the specific auction date and redemption period.
Owners with delinquent taxes often settle the balance before the auction using a payoff figure from the Tax Assessor-Collector. The payoff includes the base tax, accumulated penalty, interest, and a publication fee. Paying in full clears the lien and removes the parcel from the sale list.
Delinquent Tax Timeline
- After statutory due date: Penalty and interest begin accruing on unpaid bills.
- Mid-year: Bills move to delinquent status and prepare for the tax sale.
- Late summer through fall: Publication of delinquent parcels in the local paper.
- Scheduled auction date: Tax sale auction held at the courthouse. Confirm exact date with the Starr County Tax Office.
- Redemption window: Statutory period for the original owner to reclaim the property. Refer to the Texas Property Tax Code for current redemption rules.
Property Tax Refund Process
The Starr County property tax refund process covers overpayments, exemption corrections, and successful protest refunds. Overpayments often happen when an escrow company sends more than the bill or when an exemption retroactively reduces the levy. Owners request refunds by submitting a written claim with supporting documents to the Tax Assessor-Collector.
Successful protest refunds arrive as a check mailed to the owner of record. Exemption refunds may apply for prior tax years when the exemption was missed in error. The office processes refunds in the order received, with most checks issuing within a few weeks of approval.
Refunds under a small dollar threshold may roll forward as a credit on the next tax bill. Owners requesting a check instead of a credit must complete a refund claim form and supply identification. Errors caused by the appraisal district or assessor office trigger automatic refunds without an owner filing.
Documents Needed for a Refund Claim
- Refund request form or written claim letter
- Copy of the original tax bill showing the amount paid
- Proof of payment such as a canceled check or receipt
- Identification matching the owner of record
- Documentation of the correction, such as an exemption approval letter
Senior Tax Deferral and Other Relief Programs
Starr County tax relief programs include a deferral option for owners age 65 or older who meet income limits. The deferral postpones collection of the tax bill, with a lien filed against the property for the deferred amount. Repayment happens when the owner sells, transfers, or passes away, with interest accruing at a statutory rate.
Disabled owners and qualified veterans can apply for similar deferrals based on income and disability status. Disaster relief provisions sometimes freeze or reduce tax bills for properties damaged in federally declared disasters. Owners affected by flooding, hurricanes, or wildfires should contact the assessor about possible adjustments.
Charitable organizations and religious institutions may apply for full exemptions on property used for qualifying purposes. Income-producing agricultural land sometimes qualifies for a special appraisal that lowers the value based on productive capacity. Each program requires its own application and supporting documentation.
Relief Program Comparison
| Program | Eligibility | Main Benefit |
|---|---|---|
| Senior Deferral | Age 65 or older with qualifying income | Postpones collection until sale or transfer |
