Your Property Tax Bill Just Went Up. Here's What To Do About It.

Every spring, Collin County homeowners open a notice from the appraisal district and have one of two reactions: a quiet sigh of relief — or a full-on double take. If your 2026 appraisal notice made you wince, you're not alone. And here's the part most homeowners don't know: you can push back.

In Texas, property owners have the legal right to protest their assessed value every single year. It doesn't require a lawyer. It doesn't require an appeal with no chance of winning. And if you have the right documentation, it works. What it does require is showing up — because if you don't file, the appraisal district keeps every dollar on the table.

Why Your Tax Bill Matters More Than You Think

Texas has no state income tax — which sounds great until you see the property tax bill. The effective rate in Plano runs around 2.19% of assessed value per year, covering the City, Plano ISD, Collin County, and other taxing entities. On a home assessed at $522,000, that's roughly $11,432 per year — or close to $1,000 a month in property taxes alone.

And every year the appraisal district raises your assessed value without you pushing back, that number compounds. A $50,000 over-assessment doesn't just cost you $1,095 this year — it costs you that every year until you sell or successfully protest.

The district isn't malicious. They're assessing thousands of properties with limited individual inspection. Mistakes happen — and in a declining market, those mistakes tend to favor the taxing authority, not the homeowner.

How the Protest Process Works

Texas Tax Code gives every property owner the right to protest their assessed value under two grounds — and you can use both at the same time:

• Incorrect Market Value (§41.41(a)(1)): You believe the district assessed your property for more than it would actually sell for in the open market — backed by comparable sales.
• Unequal Appraisal (§41.41(a)(2)): Your home is assessed at a higher rate per square foot than comparable neighboring properties assessed by the same district, in the same tax year. This is a fairness argument — and it works even if the raw number seems defensible in isolation.

Here's how the timeline looks for Collin County homeowners in 2026:

One important note: the informal review is your friend. Many protests settle there without ever going to a formal ARB hearing. Go to the informal first. If you get a partial reduction and believe more is warranted, you can still request an ARB hearing.

What The Ameizen Team Does for Our Clients

This is one of the most practical ways we serve homeowners beyond the transaction — and it's something we're genuinely proud to offer. When we prepare a property tax protest for a client, here's what they receive:

• Full Protest Report — A professionally formatted document covering property summary, assessment history, market trend analysis, comparable sales, condition analysis, and an unequal appraisal analysis comparing your home to neighbors assessed by the same district.
• A Clear Ask — We calculate both a primary market value target and a fallback equity target so you walk in knowing exactly what to say and why.
• Cover Letter — A formal letter addressed to the Appraisal Review Board, summarizing every argument in clean, professional language — ready to submit with the protest form.
• Hearing Prep Guide — A plain-English coaching document that walks you through the likely objections, how to respond to each one, what to bring, how to present your case in 15 minutes, and what mistakes to avoid.
• Estimated Tax Savings — A breakdown of your projected annual and 5-year savings by taxing entity, so you understand the real dollar impact of a successful protest.

We do the homework. You walk in prepared. That combination changes outcomes.

A Real Case Study: Parkway Estates, Plano

Here's a look at a recent protest we prepared for a client in the Parkway Estates neighborhood of Central Plano. The numbers are real. The situation is exactly what you might face if you own a larger, older home in an established Plano subdivision.

Note: Client name and identifying details have been omitted. All financial data is from the actual protest report prepared for this property. Results shown are targets — not guarantees. Individual outcomes will vary based on the evidence presented and the appraisal district's response.

The Situation

The subject property is a 4,381 sq ft, 5-bedroom, 5-bathroom home on just over an acre in the Parkway Estates subdivision of Central Plano (75023). The home was built in 1984 and has seen significant deferred maintenance — an aging system, original construction throughout most of the home, and a swimming pool currently in disrepair.

Collin Central Appraisal District proposed a 2026 assessed value of $894,326 — an increase of 7.5% over the prior year's value. That might sound modest. Here's the problem.

The Market Was Moving in the Wrong Direction

NTREIS (the regional MLS data source) shows what actually happened to home prices in the 75023 zip code in the 12 months leading up to the January 1, 2026 appraisal date:

The market went down 6–9%. The assessment went up 7.5%. That's the argument in one line — and it's exactly the kind of contradiction that a protest is built to surface.

The Comparable Sales Evidence

We pulled closed sales from within Parkway Estates and the immediately surrounding streets — all arms-length MLS transactions within 12 months of the appraisal date. Sale prices are shown net of seller-paid concessions to reflect true market value.

Comp A is the anchor. It's the same subdivision. It sold AS-IS, priced explicitly for renovation — the category that most closely matches this subject property. The district assessed the subject at $894,326. An AS-IS buyer in the same neighborhood paid $610,000 in May 2025.

That gap is the argument.

The Condition Factors

Beyond the comps, the property has specific condition factors that buyers would price in — and that the district's mass appraisal process can easily overlook:

• Pool in disrepair: A non-functional pool isn't an amenity — it's a liability. Remediation typically runs $15,000–$40,000+. Buyers either discount aggressively or walk away entirely. We applied a 5% condition adjustment.
• Deferred maintenance throughout: Original 1984 construction with no significant updates. Updated comparable homes in the same subdivision command premiums of $80,000–$150,000+ over non-updated peers. We applied a 3% condition adjustment.
• Functional obsolescence: A 40-year-old home without renovation carries real-world discounts in systems, layout, and finishes versus renovated comps in the same price range.

The Unequal Appraisal Argument

We also ran an equity analysis comparing this home's assessed value per square foot against four neighboring properties in Parkway Estates — all assessed by CCAD for the same 2026 tax year:

The subject is assessed 5.4% above the neighborhood average — by the same district, in the same tax year. Texas law allows you to protest on that basis alone. Applying the neighbor average to the subject's square footage produces an equity-based target of $848,000.

The Ask and the Potential Savings

Based on the comparable sales and condition analysis, we calculated a primary market value target of $734,000 — a requested reduction of $160,326 (17.9% below the proposed assessment). The equity-based fallback position is $848,000.

To be direct: winning a $160,000 reduction is an ambitious ask, and outcomes vary. But the evidence is strong, the process is fair, and the alternative is simple — do nothing and keep paying the higher bill. We'd rather put our client in the best possible position to fight for every dollar.

If You Don't File, You've Already Lost

Here's the honest truth about property tax protests in Texas: most homeowners don't file. They open the notice, wince, and figure it's too complicated or not worth the effort. The appraisal districts count on exactly that.

Protests don't always succeed — and results are never guaranteed. But a well-documented protest with real comparable sales, market trend data, and a clear condition analysis changes the conversation. The district has to respond to evidence. When you show up empty-handed, there's nothing for them to respond to.

Even a partial reduction matters. A $50,000 decrease saves around $1,085 per year in Plano — every year, until you protest again or sell.
