Lubbock County, TX property tax protest guide for 2027

What deadline matters first

For most Lubbock County homeowners, the regular 2027 protest deadline is May 17, 2027. Lubbock CAD states that the protest deadline is May 15 or 30 days after the notice was mailed, and Texas law uses the later of May 15 or the 30-day notice deadline. Because May 15, 2027 falls on a Saturday, Texas deadline rules move the regular county-wide date to the next regular business day, May 17, 2027. Lubbock CAD protest information, Texas Tax Code Section 41.44, Texas Comptroller property tax calendar

If your mailed appraisal notice gives you a later 30-day date, use the later date. Do not wait if you are unsure. The formal protest is handled through Lubbock Central Appraisal District and heard by the Lubbock County Appraisal Review Board.

Recent Lubbock CAD notice materials also describe informal inquiry options that begin April 1 and end April 30 before the formal protest deadline. An informal inquiry can help you ask questions, but it is not a substitute for filing a formal protest by the deadline if you want the Appraisal Review Board to hear your case.

For planning, TaxSauce uses a recent county-wide median effective tax rate estimate of 1.49%. This is only a rough county-level estimate. Your actual tax impact depends on your city, school district, special districts, exemptions, taxable-value limits, and final tax rates. Ownwell Lubbock County property tax trends

For a sense of protest volume, Lubbock CAD’s 2025 Annual Report listed 30,035 total formal protests for 2025 as of October 2025. That appeal count shows that formal protests are a normal part of the local property tax system, not something unusual for a homeowner to consider. Lubbock CAD 2025 Annual Report

The common value appeal

The common value reason is Incorrect appraised (market) value. Use this when the appraisal district’s value is higher than what recent sales, your home’s condition, a fee appraisal, or other market evidence supports as of January 1, 2027.

Texas generally appraises taxable property at market value as of January 1. In plain English, market value means what the property would likely sell for in an open-market sale between a willing buyer and a willing seller under normal conditions. Texas Comptroller valuing property

For 2027, the strongest reusable sale evidence usually starts with 2026 arm’s-length sales. Arm’s-length means a normal open-market sale, not a forced sale, family transfer, distressed deal, or transaction with unusual concessions that make the price less reliable.

Lubbock CAD does not publish a hard maximum distance or maximum number of comparable sales for residential value protests. TaxSauce therefore screens conservatively, usually looking first within the same neighborhood or about one mile when enough similar sales exist, and organizing up to 10 candidate sales for review.

Other reasons you might appeal

Some protests are not just about whether the market value is too high. If your appraisal notice or appraisal record shows another problem, preserve the official reason label that matches it.

• Value is unequal compared with other properties: Your property may be appraised higher than a reasonable number of comparable properties after fair adjustments for size, condition, location, and other differences.
• Property should not be taxed in a taxing unit: The property is being taxed by a city, school district, or other taxing unit that should not have jurisdiction over it.
• Property is not located in this appraisal district or otherwise should not be included on the appraisal district's record: The property is assigned to the wrong appraisal district or should not be on this district’s record.
• Failure to send required notice: A required appraisal or statutory notice was not sent or delivered as required.
• Exemption was denied, modified or cancelled: A homestead, over-65, disabled person, disabled veteran, or other exemption was denied or changed.
• Temporary disaster damage exemption was denied or modified: The district denied or changed a temporary disaster damage exemption.
• Ag-use, open-space or other special appraisal was denied, modified or cancelled: A special land appraisal, such as agricultural use, open-space, or timber, was denied or changed.
• Change in use of land appraised as ag-use, open-space or timberland: The district says land with special appraisal changed use, which can trigger additional tax consequences.
• Incorrect appraised or market value of land under special appraisal: The special-appraisal land value, productivity value, or related market value is incorrect.
• Owner’s name is incorrect: The appraisal record lists the wrong owner name.
• Property description is incorrect: The legal description, acreage, building description, or other identifying detail is wrong.
• Incorrect damage assessment rating for a property qualified for a temporary disaster exemption: The disaster-damage rating category is wrong.
• Circuit breaker limitation on appraised value for non-homestead real property was denied, modified or cancelled: A qualifying non-homestead property did not receive the applicable appraised-value limitation, or the limitation was changed.
• Other: Another appraisal-district action or Appraisal Review Board matter applies, and the standard labels do not describe it well.

If more than one official reason fits, keep your evidence separated by reason. Lubbock ARB procedures say evidence should be confined to the reasons stated in the protest, so it is important to choose carefully. Lubbock ARB 2026 Hearing Procedures

If your Notice of Assessment says something else changed

A Notice of Assessment means the homeowner’s notice telling you what the appraisal district changed or placed on the property record. In Lubbock CAD materials, this is generally an appraisal notice or notice of appraised value. It may include the proposed value, exemptions, property details, protest form, and information about the appraisal process. Lubbock CAD FAQ, Lubbock CAD appraisal notice insert

Read the notice line by line. Look for changes in market value, appraised value, exemptions, ownership, property description, land classification, or taxing units. A value increase may call for Incorrect appraised (market) value, but an exemption change or property-description mistake may call for a different official reason.

Do not assume the deadline is the same for every neighbor. The safest first step is to compare the mailing date and protest deadline on your own notice with the regular May 17, 2027 date.

What evidence helps

Good evidence is specific, dated, and easy for another person to follow. For a market-value protest, start with sales of similar homes from 2026, close to the January 1, 2027 valuation date. Give more weight to homes with similar size, age, location, condition, and construction type.

Useful documents can include closing statements, MLS or realtor-provided comparable-sale sheets, sworn or documented sales information, a signed fee appraisal, LCAD’s appraisal card or comparable sales, and dated condition evidence. Condition evidence can include photos, contractor estimates, repair bills, surveys, blueprints, deed records, or measurements. Lubbock ARB 2026 Hearing Procedures

Treat distressed sales, related-party transfers, forced sales, major seller concessions, and very different properties cautiously. They may still explain the market, but they are usually weaker unless you can clearly explain and adjust for the differences.

Lubbock ARB procedures say standard residential hearings are limited to 20 minutes per parcel. That means organization matters. Put your best evidence first, label each item, and connect each document to the official protest reason you filed. Lubbock ARB 2026 Hearing Procedures

Evidence handling also matters. Lubbock procedures describe evidence by email before the hearing, USB in accepted formats, or printed copies. Remote teleconference, videoconference, or affidavit hearings require notarized affidavit evidence submitted before the hearing. The procedures also state that paper evidence is retained or scanned, mobile-phone evidence is not accepted directly, and evidentiary pictures are limited to 10 and should be current.

What the board can and cannot decide

The Lubbock County Appraisal Review Board is the official local protest body. Lubbock CAD’s FAQ describes the Appraisal Review Board as an independent, impartial group of citizens authorized to resolve disputes between taxpayers and the appraisal district. Lubbock CAD FAQ

The board can decide the protest issues within its authority, such as value, unequal appraisal, exemptions, property description errors, ownership errors, and other appraisal-record matters listed on your protest. It decides based on the evidence and the official reasons stated in the protest.

The board does not set tax rates, decide school or city budgets, waive taxes because a bill feels unaffordable, or guarantee a future-year value. A lower appraised value may lower taxable value, but your final tax bill still depends on exemptions, limits, and the tax rates adopted by your taxing units.
