Denton County 2027 property tax protest overview

For tax year 2027, Denton County property is generally valued at market value as of January 1, 2027. The regular protest deadline is the later of May 17, 2027 or 30 days after Denton Central Appraisal District delivers the notice of appraised value. The Texas Tax Code sets the usual rule as May 15 or the 30th day after notice delivery, whichever is later; the 2027 county-wide date moves to May 17 because May 15, 2027 falls on a Saturday (Texas Tax Code § 41.44).

Denton CAD’s local Property Owner’s Notice of Protest, Form 50-132, includes the common value checkbox: “Incorrect appraised (market) value and/or value is unequal compared with other properties.” The same form says a property owner can use it to file a protest with the appraisal review board and that the form should be filed with the appraisal district office, not the Comptroller (Denton CAD Form 50-132).

Which Denton County protest reasons fit which problems?

Use the official reason that matches the appraisal action you disagree with. For a market-value or unequal-appraisal dispute, Denton CAD’s combined checkbox is the value-focused option:

  • Incorrect appraised (market) value and/or value is unequal compared with other properties. Use this when comparable sales, an appraisal, condition evidence, or unequal-appraisal evidence supports a lower value.
  • Property should not be taxed in _____ (taxing unit). Use this if the record assigns the property to a taxing unit that should not tax it.
  • Property is not located in this appraisal district or otherwise should not be included on the appraisal district’s record. Use this if the property should not be on Denton CAD’s records.
  • Owner’s name is incorrect. Use this if the roll lists the wrong owner.
  • Property description is incorrect. Use this if characteristics, improvements, land description, or other description details are wrong.
  • Failure to send required notice. Use this when a required notice was not sent as required.
  • Exemption was denied, modified or cancelled. Use this for a denied, changed, or removed exemption.
  • Temporary disaster damage exemption was denied or modified. Use this for a disputed temporary disaster exemption decision.
  • Ag-use, open-space or other special appraisal was denied, modified or cancelled. Use this for a denied or removed special appraisal.
  • Incorrect appraised or market value of land under special appraisal for ag-use, open-space or other special appraisal. Use this for a value dispute involving land under special appraisal.
  • Change in use of land appraised as ag-use, open-space or timberland. Use this if Denton CAD determined a qualifying land use changed.
  • Incorrect damage assessment rating for a property qualified for a temporary disaster exemption. Use this when the disaster damage rating is disputed.
  • Circuit breaker limitation on appraised value for all other real property was denied, modified or canceled. Use this for a disputed circuit-breaker limitation decision.
  • Other. Use this for another appraisal district, chief appraiser, or appraisal review board action that applies to and adversely affects the owner.

Building comparable-sale evidence for Denton County

For the 2027 regular cycle, focus comparable-sale evidence on arm’s-length, open-market sales of similar properties adjusted to the January 1, 2027 valuation date. Residential market-data review in a county over 150,000 population uses sales within 36 months of the valuation date, so the reusable sale window is 2024-01-01 through 2027-01-01.

Start with the same neighborhood or market area when possible. Then compare property type, school and taxing context, improvement square footage, lot size, age, condition, access, amenities, view, and legal or economic influences such as easements and deed restrictions. Texas law does not publish a fixed Denton County radius, gross-living-area variance, lot-size variance, or maximum number of homeowner comparable sales for ARB evidence. A conservative working set is up to five strong sales within about five miles, but closer and more similar sales should carry more weight.

Exclude or explain transactions that are not normal market evidence. Related-party transfers, distressed or compulsory transactions, package or bulk sales, unusual concessions, and atypical financing may need to be discounted or adjusted. Helpful documentation can include sale date, sale price, listing or appraisal materials, photos, repair estimates, property characteristics, the source of the sale information, adjustment notes, and a concise value conclusion.

Filing options and the Appraisal Review Board

Denton County’s official protest body is the Appraisal Review Board (ARB), and Denton materials also refer to the Denton County Appraisal Review Board. Denton CAD’s form lists the district office at 3911 Morse Street, Denton, TX 76208 and includes the eProtest site. KERA reported that Denton CAD recommended its eFile portal, while owners could also download and print a protest form for mail or office drop-off (Denton CAD Form 50-132, KERA).

For a sample volume metric, KERA reported that Denton Central Appraisal District had received about 40,000 protests as of the Friday before the May 15, 2024 deadline and expected about 100,000 property owners to challenge appraised values by that deadline (KERA).

If the protest is not resolved before the hearing, the ARB hears the dispute and determines the appraisal’s standing. KERA reported that hearing notices are mailed at least 14 days before the scheduled hearing and that Denton CAD’s process may involve phone, video, or in-person hearing details (KERA).

Estimated tax impact

This page uses a 1.73% estimated effective tax rate for Denton County. That means each $10,000 of reduced taxable value estimates about $173 of annual tax impact before property-specific factors. This is a county-level estimate only. Your actual combined rate can differ because Denton County properties sit in different school districts, cities, special districts, and exemption situations.

Key questions

Answers before you file

When is the 2027 Denton County property tax protest deadline?

For the 2027 regular protest cycle, Denton County owners generally must file by May 17, 2027, or 30 days after Denton CAD delivers the notice of appraised value, whichever is later. May 15, 2027 is a Saturday, so the county-wide regular deadline moves to the next regular business day.

What protest reason should I consider for a value dispute?

The most common value issue is Denton CAD’s combined checkbox: “Incorrect appraised (market) value and/or value is unequal compared with other properties.” Use it when adjusted comparable sales support a lower January 1, 2027 market value, or when similar properties are appraised lower after fair adjustments.

What comparable-sale evidence is most useful in Denton County?

Good Denton County comparable sales are arm’s-length, open-market transactions involving similar properties. For the 2027 January 1 valuation date, residential sales within 36 months means 2024-01-01 through 2027-01-01, with stronger weight for the closest, most similar sales after adjustments.

How much could a lower appraised value affect taxes?

The estimated Denton County effective tax rate used here is 1.73%, so a $10,000 value reduction would estimate about $173 in annual tax impact before case-specific differences. Actual combined rates vary by school district, city, special district, and exemptions, so use your tax bill for a property-specific estimate.

Who hears Denton County appraisal protests?

The official protest body is the Appraisal Review Board (ARB), and Denton County materials refer to the Denton County Appraisal Review Board. File the written protest with Denton Central Appraisal District, then prepare for informal review and, if unresolved, an ARB hearing under the official procedures.

Common questions

Review before you file

What is the Denton County 2027 protest deadline?

The regular county-wide 2027 deadline is May 17, 2027. If Denton CAD delivers your notice of appraised value later, your deadline may be 30 days after delivery if that date is later than May 17.

Which Denton CAD protest reason fits a high appraised value?

For a value dispute, Denton CAD’s Form 50-132 uses: “Incorrect appraised (market) value and/or value is unequal compared with other properties.” Select every official reason that applies to preserve the issues you want the ARB to hear.

What sales should I use for a 2027 Denton County protest?

Use arm’s-length, open-market sales of similar properties. For the 2027 January 1 valuation date, residential comparable sales should fall between 2024-01-01 and 2027-01-01, with stronger weight for the most similar sales closest to January 1, 2027.

Who hears Denton County property tax protests?

The Appraisal Review Board (ARB), referred to in Denton materials as the Denton County Appraisal Review Board, hears unresolved protests. A Denton CAD appraiser may review the protest first, but unresolved disputes proceed to the ARB hearing process.
