If you just opened your Williamson County property tax bill and felt that familiar punch to the gut, you're not alone. Round Rock homeowners are seeing bills jump $800-$1,500 this year alone, while Cedar Park residents face increases that would make anyone question if their assessment is actually correct. The truth? Many Williamson County properties are assessed 15-25% higher than their true market value, and the county isn't going to volunteer to fix that mistake.
Williamson CAD processes over 200,000 properties using automated systems that can't account for your home's specific issues. That foundation crack, outdated kitchen, or busy road noise? The computer doesn't know. Your $450,000 home might be assessed like your neighbor's renovated property, even though yours needs $30,000 in updates. We've seen Georgetown homes assessed $75,000 over market value simply because the system grouped them with newer construction nearby.
The appeals process exists because errors are common, not rare. Last year, Williamson County's Appraisal Review Board approved reductions in over 60% of cases where homeowners presented proper evidence. The problem isn't whether you have a case β it's knowing how to prove it and having time to fight a system designed to discourage you.
Unlike Travis County's more predictable patterns, Williamson County's rapid growth creates assessment chaos. New developments in Leander push up values for older homes miles away. Hutto's explosion affects Taylor assessments. The CAD struggles to keep pace, often using outdated comparables or missing key factors that affect your property's actual worth. We track these patterns daily and know exactly where the system breaks down.
Your protest deadline is approaching fast β typically May 15th or 30 days after your notice arrives. Miss it, and you're locked into paying the full amount for an entire year. That's potentially $2,000+ in unnecessary payments because you didn't have time to navigate their bureaucratic maze.
Every month you overpay costs you money that never comes back. A $2,000 annual overpayment becomes $20,000 over a decade β money that could fund your retirement, your kids' college, or simply stay in your family instead of government coffers. Williamson County homeowners who successfully protest save an average of $1,200-$2,800 annually, year after year, because lower assessments compound over time.
The process intimidates most people into accepting whatever bill arrives. Gathering comparable sales, calculating square footage adjustments, preparing evidence packets, attending hearings β it's designed to make you give up. That's exactly why we handle everything while you go about your normal life.
You spend five minutes providing basic property details. We spend months building your case, filing paperwork, and presenting evidence to the Appraisal Review Board. Our licensed professionals know which comparables matter, how to calculate adjustments, and what arguments work with Williamson County hearing officers. You don't attend meetings, chase deadlines, or stress about procedures.
When we win β and we do in 94% of cases β you keep 75% of every dollar saved. If we don't reduce your taxes, you owe nothing. It's the only risk-free way to fight back against a system that counts on your compliance. Stop wondering if you're overpaying and find out for certain.
