Property Tax Assessment Checker
This tool organizes a review of your assessment. You enter the values from your notice of appraised value and your property's characteristics; it calculates the year-over-year change, screens for conditions that may warrant further review, and builds a preparation checklist. It runs entirely in your browser and stores nothing.
What it can and cannot determine
- Can: calculate changes between values you provide, screen for issues worth checking (large increases, cap interactions, sale-price relationships, condition documentation needs), and organize your evidence and preparation.
- Cannot: determine your property's market value, verify your inputs against official records (yet), produce comparable properties, or tell you whether a protest will succeed.

Texas rules apply. This tool screens your figures against Texas assessment rules only — a different state's caps, notice, and deadlines do not apply here.
Everything runs in your browser. Nothing you enter is stored or sent anywhere.
