If you just opened your Collin County property tax bill and felt that familiar punch to the gut, you're not alone. With median property taxes hitting $7,400 annually in areas like Plano and Frisco, thousands of homeowners are discovering they're paying hundredsâsometimes thousandsâmore than they should. The frustrating truth? Collin Central Appraisal District makes mistakes, and those mistakes cost you money every single month.
Collin County's explosive growth creates a perfect storm for over-assessment. When neighborhoods like Legacy West in Plano or The Star district in Frisco develop rapidly, CAD assessors struggle to keep pace with actual market values. They often rely on outdated comparable sales or apply blanket increases that don't reflect your property's true worth. Meanwhile, you're stuck paying inflated taxes on an overvalued assessment while your neighbor with a similar home pays significantly less.
The numbers tell the story: Collin County's effective tax rate of 1.49% means a $500,000 home generates $7,450 in annual taxes. But here's what CAD doesn't advertiseâsuccessful protests reduce assessments by an average of 12-18%, saving homeowners $900-$1,340 per year. That's real money staying in your pocket instead of funding government coffers.
You know you're probably overpaying, but who has time to research comparable sales, prepare evidence packets, and attend hearings during business hours? Between work, family, and everything else on your plate, tackling the Collin County property tax protest process feels impossible. That's exactly why most homeowners just pay the bill and hope next year will be betterâwhile continuing to overpay month after month.

You spend five minutes providing basic information, and we spend months building your case, filing paperwork, and fighting for maximum savings. No time off work, no confusing forms, no stress.
Our success comes from understanding exactly how Collin CAD operates and where they consistently make errors. We analyze recent sales in your specific neighborhoodâwhether that's West Plano, downtown McKinney, or new construction in Friscoâto prove your property is overvalued.

Here's how our fee structure works: if we don't reduce your assessment, you pay nothing. If we save you $1,200 annually, our fee is $300âyou keep $900 in savings every year going forward. If we save you $2,000, you pay $500 and keep $1,500. You always come out ahead, and you never risk losing money on the process.
Consider this: the average successful Collin County property tax protest saves homeowners $1,102 annually. Over five years, that's $5,510 in your pocket instead of the county's. Our fee is a one-time cost for ongoing annual savings, making this one of the smartest financial decisions you can make as a Collin County homeowner.
Texas law gives you until May 15th (or 30 days after receiving your notice) to file your property tax protest. Miss this deadline, and you're locked into paying the full assessment for another year. Every day you wait costs you approximately $3-$8 in unnecessary taxes, money that could stay in your account instead of funding county operations.

The deadline to file a property tax protest in Collin County is May 15th or 30 days after your appraisal notice is mailed, whichever is later.

Visit collincad.org and use the property search tool to enter your address and view your current and historical property valuations. Your appraisal notice, typically mailed by mid-May, shows both market and assessed values for your Plano or Allen home. Comparing your assessed value to recent sales of similar properties in your neighborhood helps determine if a protest is warranted.
A successful property tax protest reduces your property's assessed value, directly lowering your annual tax bill for that year and potentially future years. The reduction becomes part of your property's official record with Collin CAD, meaning ongoing savings until the next reassessment cycle. Most successful protests in Texas result in 10-20% reductions, though some achieve even greater savings depending on the evidence presented.

Most services work on contingency, meaning you only pay if they successfully reduce your assessment.
Your property may be overassessed if similar homes in your Plano or Wylie neighborhood recently sold for 10% or more below your assessed value. Other red flags include significant property damage not reflected in your assessment, incorrect property details on your appraisal record, or assessments that increased dramatically without corresponding improvements. Comparing your per-square-foot assessment to nearby sales provides the clearest indication of potential overassessment.
