Tarrant County, Texas property tax appeal guide for 2027

Tarrant County homeowners who disagree with their 2027 appraisal can file a protest with the Tarrant Appraisal Review Board. For most residential value cases, the core question is whether TAD’s value is too high for the January 1, 2027 valuation date or whether the property is appraised unequally compared with similar properties.

Texas law generally appraises taxable property at market value as of January 1, except where a special rule applies. The Texas Comptroller also explains that the usual protest deadline is May 15 or 30 days after the appraisal district mails the Notice of Appraised Value, whichever is later. For 2027 in Tarrant County, May 15 falls on a Saturday, so the regular deadline moves to Monday, May 17, 2027 under the Texas Tax Code weekend and holiday rule. Always use the deadline printed on your TAD notice when it is later than May 17. Texas Comptroller protest overview Texas property tax deadline calendar Texas Tax Code Chapter 23 PDF

What to file

Tarrant’s local form is the TARRANT APPRAISAL REVIEW BOARD NOTICE OF PROTEST. The form states that the protest deadline is May 15 of the current tax year or the deadline printed on the Property Value Notice from TAD, whichever is later. For a 2027 protest, use the 2027 form or the current version available from TAD, review every selected reason, and keep a complete copy of what you submit. Tarrant ARB Notice of Protest

Protest reasons homeowners commonly review

Incorrect appraised (market) value

Choose Incorrect appraised (market) value when the noticed value appears higher than the property’s January 1, 2027 market value. This is usually supported with:

• Comparable sales of similar homes
• A closing statement or purchase contract if the sale is relevant to January 1 value
• A private appraisal
• Photos, inspection reports, repair estimates, or contractor bids
• Evidence of condition problems that existed as of January 1, 2027

Value is unequal compared with other properties

Choose Value is unequal compared with other properties when similar properties are appraised at lower adjusted values or lower appraisal ratios. This is not the same as arguing that the market value is wrong. It focuses on whether the appraisal level is fair compared with comparable properties.

Combined value issue

Tarrant’s protest form also includes Incorrect appraised (market) value and/or value is unequal compared with other properties. This combined option can preserve both the market-value and unequal-appraisal issues when both may apply.

Other listed protest grounds

Tarrant’s local policy also recognizes non-value grounds, including exemption denial or cancellation, special appraisal issues, incorrect property description, situs or taxing-unit issues, failure to send required notice, temporary disaster damage issues, owner-name errors, and Other adverse actions that must be specifically described.

Comparable sale evidence for Tarrant County

Texas and Tarrant sources do not publish one universal comp rule for every homeowner protest, such as a fixed mile radius, exact GLA variance, lot-size variance, or maximum comp count. For homeowner evidence, TaxSauce starts conservatively:

• Search radius: begin within 1 mile when possible
• Candidate count: collect up to 12 possible sales
• Best evidence: similar properties in the same neighborhood, submarket, or TAD market area
• Timing: prefer sales closest to and before January 1, 2027
• Default improved-residential window: January 1, 2026 through December 31, 2026

TAD residential appraisal materials describe sales-comparison modeling that selects three to six improved residential sales and evaluates similarity using factors such as market area, property type, style, quality, size, effective year, and land size. That is why TaxSauce treats similarity and adjustment quality as more important than a rigid distance rule. TAD 2024 Residential Appraisal Manual

Good comps are usually arm’s-length, open-market sales. Exclude or clearly flag related-party transfers, foreclosure or distressed sales, unusual concessions, incomplete prices, unverified sales, and homes with major unadjusted differences. If the best comparable is slightly outside 1 mile but in the same neighborhood or market area, it may be more persuasive than a physically closer but materially different property.

What TaxSauce helps organize

TaxSauce can help estimate whether a protest is worth reviewing, organize comparable sales, prepare a comp grid, flag weak transactions, and create a homeowner evidence packet. You review the evidence, choose which protest reasons apply, consent to any filing, and submit or share the packet according to TAD and ARB instructions.

TaxSauce does not promise a reduction, a hearing outcome, or that any form is accepted as complete. The owner is responsible for reviewing the official notice, selecting the correct protest reasons, meeting the deadline, and submitting accurate information.

Local protest volume context

Tarrant County’s 2025 appraisal cycle was large. A county news release reported that TAD managed 228,224 residential protests in 2025 and that hearings were 50% fewer than prior years. This is not a success-rate promise for any individual property. It does show that residential protests are a high-volume part of the local appraisal process.

Practical filing checklist

1. Read the 2027 Notice of Appraised Value and record the deadline shown on it.
2. Confirm whether May 17, 2027 or the notice-specific deadline is later.
3. Review the noticed market value, exemptions, owner name, property description, and taxing-unit information.
4. Select the official protest reason or reasons that match the issue.
5. Gather comparable sales, purchase documents, appraisals, photos, repair evidence, maps, and written explanations.
6. Keep copies of the protest form, supporting evidence, and delivery confirmation.
7. Watch for any informal review or ARB hearing notice from TAD or the Tarrant ARB.

Bottom line

For most 2027 Tarrant County homeowners, the regular protest deadline is May 17, 2027, unless a later-mailed notice gives a later property-specific deadline. The strongest value protests usually connect the owner’s requested value to January 1, 2027 evidence, especially similar arm’s-length sales or documented condition issues.
