About txpropertymath.com

An independent, free site that shows the full arithmetic behind a Texas property tax bill, instead of asking for your contact information first.

What this site is

Three free calculators — a per-unit tax estimator, a protest savings calculator, and a 10% homestead cap check — built around Texas Comptroller rate data and the current Texas Tax Code. Every result shows the formula used to produce it, not just a final number.

What makes it different

Several existing tools cover similar ground, each with a different model:

• County appraisal districts publish authoritative records for your specific property — always the source of record, and worth checking directly.
• Some commercial services offer full representation before an appraisal review board on a contingency fee, and their calculators are generally a step toward that engagement rather than a standalone, transparent tool.
• Generic 50-state calculators aren't built around Texas-specific rules like the §23.23 homestead cap or the exemption amounts set by the November 2025 constitutional propositions.

txpropertymath.com doesn't collect contact information to show a result, doesn't sell contingency-fee representation, and shows every formula it uses. It is a calculator, not a substitute for your appraisal district's own records or for professional representation.

Who maintains this site

Maintained by txpropertymath.com, an independent Austin, Texas publisher. No client names or case details appear anywhere on the site, because none are involved — every number shown is computed from what you enter. Full data sources and formulas are on the methodology page.

What this site is not

It is not tax or legal advice, not a government site, and not a property tax consulting service. See the disclaimer for what to do if you need representation or advice specific to your situation.
