Texas Tax Code § 11.13
Texas Homestead Property Tax Cap Calculator
Quantify a Texas residence homestead's property-tax bill under the post-Proposition 4 framework: the $100,000 school-district exemption (Tax Code § 11.13(b)), the additional $10,000 for owners 65+ or disabled (§ 11.13(c)), the $5,000 mandatory non-school minimum exemption, the 10% appraisal cap (§ 23.23), and the three-year non-homestead 20% pilot cap on property under $5M (§ 23.231, sunsets December 31, 2026). Surfaces the cap-versus-market gap and the school-district tax ceiling for 65+/disabled owners.
Texas Constitution Art. XVI § 28
Texas Wage Garnishment Protection Calculator
Determine whether the Texas Constitution Art. XVI § 28 wage-protection blocks a creditor's garnishment, and — where one of the six federal-supremacy or family-law exceptions applies — compute the maximum withholding under the federal Consumer Credit Protection Act (15 U.S.C. § 1673), the Texas Family Code § 158.009 50% support cap, the 34 C.F.R. § 34.19 federal student-loan AWG (15% of disposable earnings), and the IRC § 6334 IRS levy exempt-amount table. Texas is one of four states (TX, NC, PA, SC) that affords constitutional wage-protection against consumer creditors.
Texas Tax Code Chapter 41 — § 41.41 (right to protest)
Texas Property Tax Protest Calculator
Score a Texas property tax protest under Tax Code Chapter 41 — § 41.41 protest grounds, § 41.44 May-15-or-NOAV+30 filing deadline, § 41.45 hearing mechanics, and § 41.71 judicial appeal — and project expected reduction, tax savings, and a per-pay-period filing deadline. Three-tier path: informal staff conference (≈ 40% success, 8% typical reduction), formal Appraisal Review Board hearing (≈ 30%, 10%), judicial appeal (≈ 45%, 15%). Evidence-weighted: comparable sales, recent purchase price, and a reasonable claimed reduction (0-30%) drive the strength score that scales the success probability.
