How to Protest Your Property Taxes in Dallas: What Every DFW Homeowner Should Know

How do you protest property taxes in Dallas, Texas?

File a Notice of Protest with the Dallas Central Appraisal District (DCAD) or the Collin Central Appraisal District (CCAD) by May 15 — or 30 days after your appraisal notice arrives, whichever is later. Bring evidence showing your home's fair market value is below the assessed amount, using recent comparable sales from your neighborhood. In 2024, 84% of Dallas County protests resulted in a value reduction, and the average savings exceeded $1,000 per year. Under Texas law, the appraisal district cannot raise your assessed value as a result of your protest — there is no financial downside to filing.

Property taxes in Texas aren't subtle about themselves.

The state has no income tax, and schools and local governments are funded almost entirely through property assessments. That math lands squarely on homeowners — and in Dallas, it hits harder than most places. The median annual property tax bill in Dallas County is $4,489, more than $2,000 above the national median. Texas ranks among the top 10 highest property tax states in the country.

The frustrating part: 76% of Texas homeowners say they were surprised or shocked by their most recent tax bill. The maddening part: fewer than one in three actually does anything about it.

That gap is worth real money to you.

In Dallas County alone, over 206,000 protests were filed in 2024 — about 24% of all parcels — and 84% of those protests resulted in a reduced value. The average successful protester saved more than $1,000 per year. In Collin County, where median home values dropped 6.1% year-over-year as of early 2026, the average successful protest produced a $25,624 reduction in appraised value.

The people who aren't protesting are, in effect, overpaying. Every year. And there's no penalty for trying.

The most important thing to know before you do anything else: Under Texas Tax Code Section 41.43, the Appraisal Review Board cannot raise your property's value as a result of a protest you filed. The only outcomes are that your value goes down or stays where it is. There is nothing to lose.

How the Protest Process Works in Dallas County

The Dallas Central Appraisal District sends its Notices of Appraised Value every spring. The standard filing deadline is May 15 — or 30 days after your notice is mailed, whichever is later.

One thing DCAD does differently from most Texas counties: they won't conduct an informal review unless you submit your evidence and your opinion of value at the same time you file. Don't file a blank protest expecting to show up empty-handed later. Come prepared from the start.

Here's how the process unfolds:

1. File your Notice of Protest via DCAD's online uFile system at dallascad.org, by mailing Form 50-132, or in person. Select "incorrect appraised (market) value and/or value is unequal compared with other properties" as your protest reason — this preserves the broadest set of options and post-hearing appeal rights.

2. Submit your evidence at the time of filing. Include your opinion of value and your supporting comparable sales. DCAD requires this upfront.

3. Informal hearing — DCAD schedules a review with one of their appraisers. This is where most protests get resolved. Come with your data, be specific, and don't argue about how painful your tax bill feels. Argue about whether the number they assigned to your home reflects what it would actually sell for today.

4. ARB hearing (if needed) — if the informal review doesn't produce a satisfactory result, you can take your case to the Appraisal Review Board. For 2026, Dallas County designated five Saturday hearings: June 6, June 13, June 20, June 27, and July 11.

The ARB hears thousands of cases. Bring organized, specific evidence. State your opinion of value, present your strongest two or three comparable sales, and keep it concise. You typically have 15 minutes.

Collin County Homeowners Have a Stronger Case Right Now

If your home is in Plano, Frisco, McKinney, Allen, or anywhere else in Collin County, the market data is firmly on your side in 2026.

The average home value in Collin County fell 6.1% year-over-year as of March 2026 — the steepest decline the county has recorded in decades. Plano's median sale price dropped from $550,000 in March 2025 to $490,000 by March 2026. That kind of correction doesn't always show up in CCAD's assessed values, which means many homeowners are currently paying taxes on a number that no longer reflects what their home would sell for.

There's also a specific trap for Frisco and Plano homeowners: CCAD frequently bases appraised values on the most recent new-construction sale prices, which can overstate the value of homes built even two or three years earlier. If CCAD drew comparisons from a nearby new subdivision when valuing your 2019 build, your assessed value is likely inflated.

File online at collincad.org using the e-Services portal. In 2024, CCAD processed over 118,000 protests — 26% of all parcels — and 70% resulted in a reduction.

How to Build Your Evidence Package

The argument that wins a property tax protest is not "my taxes are too high." It's "my home wouldn't sell for what you say it's worth." Those are very different conversations, and only one of them produces a reduction.

Comparable sales are the foundation. Find three to five recent arm's-length sales of homes similar to yours — same neighborhood or subdivision, within a quarter mile when possible, similar square footage (within 15-20%), similar year built, similar condition — that sold below your assessed value. The most relevant comps closed in the 6-12 months before January 1, 2026, which is the valuation date the appraisal district is working from.

Your agent can pull this data directly from the MLS. A strong set of comps — three or four sales supporting a value below what DCAD or CCAD assigned — is often enough to settle the case at the informal stage without going to an ARB hearing.

Document condition issues. If your home has foundation concerns, deferred maintenance, dated mechanicals, or any factor that would affect what a buyer would actually pay, photograph it and get contractor estimates. Bring copies. A credible estimate for a $15,000 foundation repair or a $12,000 HVAC replacement supports a meaningful reduction in assessed value.

Bring four copies of everything — one for you, one for the board (if it reaches that stage), one for the district appraiser, and one spare. Photos work better printed than on a phone screen.

A word on what not to say: the protest process is evidence-driven. Telling the appraiser your taxes feel too high, that you're on a fixed income, or that your neighbor's house seems overvalued without data is wasted time. The only argument that works is showing that the market wouldn't support the number on your appraisal notice.

DIY or Hire a Tax Protest Firm?

Both approaches work. The question is time versus money.

A DIY protest costs nothing and is genuinely manageable if you're comfortable pulling comparable sales and presenting data clearly. The DCAD informal stage settles 84% of cases for homeowners who show up prepared. CCAD settles 70%.

Professional tax protest firms work on contingency — typically 25-35% of the first year's savings. You pay nothing unless they win a reduction. For a $1,000 savings, that's roughly $250-$350 out of pocket. For a $3,000 reduction in Collin County, it's $750-$1,050. Whether that trade-off makes sense depends on how much your time costs you and whether you'll actually follow through on doing it yourself.

Firms that do this every year know the appraisers, know the evidence standards, and will protest on your behalf automatically. For most homeowners who've never done this before, the contingency fee is a reasonable price to get started.

If you want to protest yourself, I can pull the comparable sales for your home as part of a market value analysis — the same data used when pricing a listing, and exactly what you need for an evidence package. You can also learn more about what homeowners are spending at closing in our breakdown of Dallas seller closing costs.

Also worth knowing: if you've owned your Dallas home for a while and never filed for a homestead exemption, that's an even faster win. Dallas County homeowners receive a $140,000 school district exemption plus an additional 20% from the city and county — and late applications are allowed for up to two years retroactively.

The bottom line: Texas property taxes are high, the protest process was built for homeowners to use, and the downside risk is zero. Most people who are overpaying aren't doing it because protesting is hard — they're doing it because nobody told them where to start.

Frequently Asked Questions

What is the property tax protest deadline in Dallas?

The standard deadline is May 15 each year — or 30 days after your Notice of Appraised Value is mailed, whichever is later. Dallas County (DCAD) and Collin County (CCAD) both use this schedule. File online, by mail, or in person before midnight on May 15.

Can the appraisal district raise my value if I protest?

No. Under Texas Tax Code Section 41.43, the Appraisal Review Board cannot raise your assessed value as a result of a protest you filed. The only outcomes are a reduction or no change. There is no financial risk to protesting.

What evidence do I need for a property tax protest in Texas?

The most effective evidence is recent comparable sales — three to five homes similar to yours in your neighborhood that sold below your assessed value in the past 6-12 months. You can also include photos of condition issues and contractor estimates for needed repairs. DCAD requires evidence submitted at the time you file, not at the hearing.

What if I missed the May 15 protest deadline?

You cannot protest the current tax year's appraisal once the deadline has passed. However, Texas law allows late homestead exemption applications for up to two years retroactively, which may reduce your taxable value without a formal protest. If you missed 2026, mark your calendar for April 2027 and start gathering evidence early.

Should I hire a property tax protest company or do it myself?

Both approaches work when you come prepared. Professional firms charge a contingency fee — typically 25-35% of the first year's savings — and handle the process for you. DIY protesters who bring comparable sales data win reductions at roughly the same rate. The main advantage of hiring a firm is consistency: they protest every year automatically and know the process cold.
