Every value notice that landed in a Westover Hills mailbox this spring carried a number. For a meaningful share of Tarrant County homeowners, it was the same number they'd already seen in 2024. Not adjusted up. Not adjusted down. Simply carried forward, as if the past two years of buying, selling, and pricing in North Texas real estate hadn't happened.
That's not an error. It's a policy.
A County-Wide Decision With an Uneven Effect
According to the Fort Worth Report, in 2024, the Tarrant Appraisal District's board adopted a plan to reappraise residential properties once every two years instead of annually. The stated goal was to ease the administrative burden on homeowners and give the district more time to get each valuation right. The report estimated that 200,000 Tarrant County homes may have carried overvalued 2026 tax notices because they were frozen at their higher 2024 appraised value even as the broader market cooled.
TAD's own chief appraiser, Joe Don Bobbitt, told county commissioners that the market value of roughly 190,000 homes would likely have decreased had the district reappraised them this year.
The mechanics matter here more than that estimate. Under a biennial system, a property doesn't get a fresh look every year. It gets one every other year, and in the years between, its file inherits whatever number was on record. If the market moved down since that number was set, the gap doesn't close itself. It sits there until the district's next scheduled pass, or until an owner forces a review.
Why a Market of a Few Hundred Doors Feels This Differently
In parts of Tarrant County with more recent, comparable sales, the district has a broader set of transactions to consider when valuing homes. Those sales can help reflect market changes over time.
Westover Hills doesn't have that cushion. This is a market of roughly 275 doors inside a separately incorporated town, with home values that run from comfortable to a documented ceiling near $22 million. That range, combined with genuinely low turnover in a given year, means the mass appraisal models that work reasonably well in a subdivision with thousands of near-identical homes have very little to chew on here. A model built to find the "typical" property in a given classification struggles when the properties in that classification aren't typical of each other, and there simply aren't enough closed sales in any twelve-month window to anchor the math with confidence.
A biennial appraisal cycle can leave a value unchanged between scheduled reviews. In a market this small and varied, an individual estate may carry a value that has not been revisited for two years.
Westover Hills residents also pay into more than one taxing entity from that same appraised value. The county, the town's own municipal government, the school district, and the local hospital district all draw their tax calculations from the figure TAD sets. A single stale appraisal doesn't just affect one line on the bill. It ripples across every jurisdiction that taxes the property.
What Actually Moves a Protest for a Home Like This
The Texas Comptroller says property owners have a right to protest an appraised value, and the mechanics are the same whether the home is worth $600,000 or $16 million. The evidence that persuades an Appraisal Review Board, however, is not the same across those two homes.
For a typical subdivision property, recent comparable sales two or three streets over usually carry the argument. In Westover Hills, that kind of comp often doesn't exist within the boundary itself, so the more useful evidence tends to be a combination of things: documentation from a recent private sale if one exists, unequal appraisal comparisons drawn from the broader luxury tier rather than the immediate block, and specific, itemized repair or condition estimates that speak to why a particular property shouldn't be valued at the district's default assumption.
Countywide, this kind of pushback works often enough to matter. Roughly 9 percent of Tarrant County parcels were formally protested in 2024, and the total tax savings from those protests rose to $116 million that year, up from $111 million in 2023. Those figures span every kind of property in the county, not luxury homes specifically, but they establish something useful: protesting is a routine, expected part of how Texas property tax actually functions, not an unusual or adversarial step.
The Deadlines Don't Bend for a Slow Market
Texas gives owners a narrow, fixed window to act. A protest is generally due by May 15 or within 30 days of the date the appraisal district mailed the notice, whichever is later. Filing is done through Form 50-132, either online through the district's own portal or by mail. Once filed, the process moves through an informal review, and if that doesn't resolve the disagreement, a hearing in front of the Appraisal Review Board, an independent panel of citizens with the authority to order a correction based on the evidence presented. Those hearings are typically brief. If the outcome still doesn't reflect the property's actual condition, AppealDesk says an owner can escalate through binding arbitration or district court.
None of that changes based on how thin the comp pool is in a given neighborhood. The clock runs the same way whether the district reappraised a property this cycle or simply carried its old number forward. That's the detail easiest to miss under a biennial system: even in a year when your street wasn't walked, you still received an official notice, and you still had the right to contest it before the deadline closed.
This year's window closed in May. It will open again, and under the two-year cycle now in place, the next notice for any given Westover Hills property may again be more a carryover than a fresh look. Knowing the schedule in advance can help an owner prepare to review a notice when it arrives.
A Few Questions Worth Asking Early
Does a stale appraisal affect a home's marketability if I'm planning to sell? The appraised value used for taxation is separate from a home's list price or fair market value in a sale, but buyers and their advisors sometimes review recent tax notices during due diligence. A number that looks disconnected from a home's actual condition or recent comparable activity is worth being able to explain, whether or not it's ever formally protested.
What if this year's deadline already passed for my property? The May 15 window for 2026 has closed for most owners. The next opportunity comes with the following notice cycle, and the same evidence-gathering approach still applies whenever that notice arrives.
