Prosper is one of the fastest-growing and highest-value communities in Collin County with large luxury homes and master-planned developments. CCAD valuations in Prosper's premium communities frequently over-assess relative to current market conditions. TaxAppeal files your formal protest with the Collin Central Appraisal District — backed by comparable sales data and certified mail — for a flat $89.
Texas law lets you protest your appraised value every single year, at no cost to file. Prosper homeowners have strong grounds — here's why.
The Collin Central Appraisal District appraises thousands of properties using statistical models that apply broad market trends to entire neighborhoods. Your home's specific condition, updates, and location nuances are often missed — leading to inflated assessments.
With a median home value of $620,000 in Prosper, even a 5% over-assessment means $775 in excess annual taxes. Protesting is one of the highest-ROI financial decisions a homeowner can make.
Under Texas Tax Code §41.41, every Collin County homeowner has the legal right to protest their assessed value every single year. You don't need an attorney. TaxAppeal handles the evidence, the letter, and the certified mail filing.

The 2027 deadline is May 17, 2027 (May 15, 2027 falls on a Saturday, so Tax Code § 1.06 moves it to the next business day), or 30 days after the Collin Central Appraisal District mails your Notice of Appraised Value — whichever is later. Texas Tax Code § 41.44 sets it from the date on your notice, so check that date: if your notice is dated after mid-April, you have longer than May 17, 2027. File early; informal hearing slots fill up fast.

TaxAppeal USA is a self-service document-preparation and mail filing service. In every state we serve, including Florida, we are not property tax consultants, agents, or representatives, we do not provide tax or legal advice, and we do not represent customers before any appraisal district, board of equalization, value adjustment board, or review board. Every protest and petition is prepared for the property owner, signed by the owner, and filed in the owner’s name. In Florida we also pay your county’s Value Adjustment Board filing fee on your behalf and mail your petition to the Clerk of the Value Adjustment Board. Your petition is signed by you as the property owner under section 194.011(3), Florida Statutes. TaxAppeal USA does not sign as your representative, does not appear before the Board, and does not present evidence or argument at a hearing.
