The Dallas Central Appraisal District uses a computer-assisted mass appraisal system to value every property in Dallas County as of January 1st each year. DCAD groups properties into market areas and applies statistical models to estimate value. The system is designed for efficiency at scale — not accuracy at the individual property level. DCAD has a legal obligation under Texas Tax Code to value your property at 100% of its January 1st market value. If their model produces a number higher than your home's actual market value, you have grounds to protest.
DCAD typically mails Notices of Appraised Value in April. Your protest deadline is the later of May 17, 2027 or 30 days from the date on your notice. Dallas County sends out an enormous volume of notices, so hearings book up quickly.
Dallas home prices surged aggressively from 2020 through mid-2023, then the market shifted. Rising interest rates slowed demand, inventory increased, and days-on-market stretched significantly. In many Dallas neighborhoods, homes that were worth $450,000 in 2022 are now selling for $410,000–$430,000. DCAD's models often lag this kind of correction, leaving homeowners assessed at peak values that no longer reflect reality.
Strong DCAD protests are built on comparable sales evidence. Find recent sales within your neighborhood of homes similar to yours that sold for less than your assessed value.

We check first. If an appeal will lower your bill, we mail you a ready-to-sign kit for $89 flat. You sign it and mail it, and you keep 100% of your savings.
TaxAppeal USA is a self-service document-preparation service. We prepare a ready-to-sign appeal kit and mail it to you; you sign it and mail it to the county yourself. 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 file appeals or represent customers before any appraisal district, board of assessors, board of equalization, value adjustment board, or review board. Every appeal, protest and petition is prepared for the property owner, signed by the owner, and mailed by the owner in the owner’s name. In Florida your petition is signed by you as the property owner under section 194.011(3), Florida Statutes, and the county’s Value Adjustment Board filing fee is paid by you directly to the county. TaxAppeal USA does not sign as your representative, does not appear before the Board, and does not present evidence or argument at a hearing.
