Homestead, 65+ and veteran exemptions in Starr County

• Homestead, $140,000 off school district value (Tax Code 11.13(b), from tax year 2025). It applies to school district taxes only, so cities, counties and special districts tax the full value unless they adopt a local option.
• 65 or older, or disabled: $60,000 more off school district value (11.13(c)), plus a school tax ceiling (11.26) that usually holds the school tax at the amount from the first year you qualify. The ceiling is why many 65+ bills are lower than the examples here.
• Starr County farm-to-market/flood control tax. The 0.1984 FM&FC part of the county rate carries a $3,000 homestead exemption (Tax Code 11.13(a)).
• Local options. Each unit can add its own homestead exemption (up to 20% of value, Tax Code 11.13(n)) or a 65+ and disability exemption (at least $3,000, 11.13(d)). Starr County units' local options were not sampled, so the examples and estimator leave them out; they can only lower the bill.
• Disabled veterans. A VA disability rating takes $5,000 (10% to 29%), $7,500 (30% to 49%), $10,000 (50% to 69%) or $12,000 (70% or more) off every unit's value (11.22); $12,000 at 65 or older with a 10% or higher rating. A 100% rating, or individual unemployability, makes the homestead fully exempt (11.131), and the exemption can pass to a surviving spouse who does not remarry. See the disabled veteran exemption guide.
• The 10% homestead cap (Tax Code 23.23). The appraised value of a homestead can rise at most 10% a year plus new improvements, starting the year after your first homestead year. A newly built home is often taxed on a partial value the first year and its full value the next, before the cap starts.

There is no fee to apply for a homestead exemption. File with your appraisal district by April 30 for the year; the homestead exemption guide has the forms and county links.

Protest deadline

Who sends the bill, and when it is due

The Starr County Tax Assessor-Collector collects for Starr County: (956) 716-4800, co.starr.tx.us.

The Comptroller's county directory (checked Oct 16, 2026) does not list Starr County Memorial Hospital District, Starr County Drainage District, South Texas College District among the units the county tax office collects for, so those taxes may come on a separate bill. Your statement shows who collects each tax; if one is missing, call that unit.

When it is due. Bills for 2026 go out in October and November 2026. Taxes are due by Jan. 31 and are delinquent if not paid before Feb. 1 (Tax Code 31.02). Jan. 31, 2027 is a Sunday, so a payment made on Monday, Feb. 1, 2027 is on time (Tax Code 1.06); penalty and interest start after that. Confirm the date on your statement with your tax office. If you are 65 or older, disabled, or a disabled veteran with a homestead, you can ask about paying in four installments (Tax Code 31.031) before the first one is due.

Sources and method

How these numbers were built. Each 2025 rate is the unit's adopted rate from the Texas Comptroller's 2025 rate files and the appraisal district's adopted-rate sheet, cross-checked against 2025 appraisal roll records, and every rate was checked again on Oct 16, 2026. Where the Comptroller's file differs from the unit's own adopted rate (McAllen's city rate, the Willacy County rows and a Cameron County road and bridge line that is not on the roll), the unit's own figure is used. A 2026 rate is shown only where an adopted 2026 rate was confirmed: Cameron Appraisal District's 2026 adopted-rate sheet and the City of McAllen's rate history. Which units apply inside each city comes from 2025 roll records sampled Oct 14, 2026 (250 Hidalgo and 191 Cameron homes, and 2 Starr and 2 Willacy records). School district shares come from 2020 Census housing counts. The examples and the estimator apply state-required exemptions only. Data file: tax-rates-2025.json.
