Key Takeaways

  • In Texas, the usual protest deadline is May 15 or 30 days after your notice is delivered, whichever is later; Harris County also notes an early homestead deadline of April 30—if missed, the standard deadline applies. Texas ComptrollerHarris County Tax Office
  • File fast online through HCAD iFile; many cases resolve through iSettle (informal) before a formal ARB hearing. HCAD+1
  • Build two cases: market value (sales, condition, cost to cure) and equal & uniform (equity grid vs. comparable assessments). Texas law provides both paths. Texas StatutesFindLaw Codes
  • If you disagree with the ARB, options include binding arbitration through the Comptroller or district court/SOAH in defined circumstances. Texas ComptrollerTexas.gov
  • Consider a licensed property tax consultant or attorney—Texas Occupations Code requires registration to perform paid consulting. Vet fees, proof, and track record. Texas Statutes+1

Assumptions & Inputs (for examples only)

  • Example home: residence homestead in Harris County.
  • Illustrative assessed value bands (e.g., $300,000*; $350,000*).
  • Example composite tax rate 2.50%* for savings math; your total rate depends on overlapping taxing units.
  • Rate year and deadlines: 2025 protest season; “Last updated” snapshot September 7, 2025.
  • Examples exclude escrow timing, under/over-65 installments, or deferrals unless noted.

Pre-Flight: Claims & Sources

1. What It Is

A property tax protest asks your appraisal district (in Houston, HCAD) to correct your home’s market value and/or equal & uniform treatment. You submit evidence, negotiate informally (often via iSettle), and—if needed—present your case to the Appraisal Review Board (ARB). If you still disagree, you may pursue binding arbitration with the Texas Comptroller or file in court. Texas ComptrollerHCAD+1

Plain definition (≈50 words):
A Texas property tax protest is a formal challenge to an appraisal district’s valuation or equal and uniform assessment. Owners file by May 15 or 30 days after notice, submit evidence, and appear before an ARB if no settlement is reached. Post-ARB options include binding arbitration or litigation. Texas ComptrollerTexas.gov

2. Why It Matters (and when it doesn’t)

Why it matters (especially in Harris County):

  • Annual increases can outpace resale reality; correcting errors or over-estimates may protect your cash flow.
  • Homestead owners benefit from a 10% cap on appraised value growth, but resetting market value lower can protect future years and your equal & uniform position. Texas Comptroller
  • Equity protests can reduce taxes even when sales are thin; you argue your assessment is high vs. similar properties’ appraised values. FindLaw Codes

When protesting may not help:

  • If your evidence is weak (no comps, no photos, no contractor bids).
  • If your capped appraised value (homestead) already sits far below market; a market-value win might not change this year’s tax, though it can set up next year.

3. The Math (simple, reproducible)

Inputs & Formulas

  • Tax due ≈ Appraised Value × Composite Tax Rate.
  • Savings ≈ (Original Appraised − Reduced Appraised) × Composite Rate.
  • Equal & Uniform: show your ratio vs. median of a peer set (your Appraised Value / Property Specs vs. comparable’s appraised ratios). Relief standards live in §42.26. FindLaw Codes

Example Walkthrough (illustrative only)

  • Original appraised value: $350,000*; proposed reduction to $320,000*.
  • Composite rate: 2.50%*.
  • Savings*: ($350,000 − $320,000) × 0.025 = $750*.

Sensitivity

  • Rate differences by taxing unit shift savings.
  • Capped homesteads: if capped appraised is already $300,000, a cut to market may not change this year’s bill (cap governs), but it may protect next year.

4. Rules & Eligibility (what the law actually says)

  • Grounds to protest: market value, unequal appraisal, exemptions, special appraisal, ownership, clerical errors, etc. (see Ch. 41). Texas Statutes
  • Burden of proof: under §41.43, appraisal districts may carry a clear and convincing burden when certain evidence standards apply; if they fail, the owner prevails. FindLaw Codes
  • Equal & uniform relief: §42.26 sets court relief if your appraisal ratio exceeds peers or the median by statutory thresholds. FindLaw Codes
  • Deadlines: May 15 or 30 days after notice; Harris County notes an April 30 homestead “early” deadline, with the May 15 default if you miss the early date. Texas ComptrollerHarris County Tax Office
  • Post-ARB routes: Binding arbitration (regular or procedural) via the Comptroller; or district court (and SOAH in defined high-value cases). Texas ComptrollerTexas.gov

5. Steps & Timeline (Harris County game plan)

Step 1 — Calendar the deadline immediately

Step 2 — File the protest online (iFile) and request docs

  • Go to HCAD iFile, enter your account, and file on both market value and unequal appraisal if appropriate. Pull your property record card and sales/evidence request. HCAD

Step 3 — Assemble evidence

  • Market value: recent arm’s-length sales, time adjustments, condition photos, contractor estimates (roof, foundation, HVAC), flood/drainage context (if applicable).
  • Equal & uniform: build an equity grid (peers by age, size, style, school feeder/village), focus on appraised (not market) values. Cite first-hand data. FindLaw Codes

Step 4 — Try iSettle (informal)

  • Upload your packet; evaluate any settlement offer. If the delta is small and evidence is strong, counter once with specifics. HCAD

Step 5 — Prepare for ARB

  • Confirm date/time; bring 3 copies of exhibits. Use the Comptroller’s homeowner protest video to rehearse the flow and burden framework. Texas Comptroller

Step 6 — Post-ARB options

  • If you’re close, settle; if far apart, consider binding arbitration (deposit required; refunded if you prevail within set thresholds). Texas Comptroller

6. Risks & Pitfalls

  • Arguing emotions, not evidence. The ARB responds to market and statutory standards, not frustration. Texas Comptroller
  • Equity grid mistakes. Mixing dissimilar peers (wrong age/condition/school feeder) can sink an equal & uniform claim. FindLaw Codes
  • Missing the real deadline. Notices mailed late move the 30-day window; verify your delivery date. Texas Comptroller
  • Capped but complacent. If your capped appraised is low today, still defend market—next year’s cap calculation depends on it. Texas Comptroller
  • Hiring unlicensed help. Paid consultants must be registered under Occupations Code 1152; ask for license and disciplinary history. Texas Statutes

7. Pricing & Negotiation (make your ask clear)

  • Convert your evidence to dollar deltas: “Foundation work $12,800*; roof $9,400*; adjusted sale comps support $320,000*.”
  • For equity, show a one-page ratio table: your subject vs. median peer appraisal; state the requested value and math per §42.26 methods. FindLaw Codes
  • Settlement posture: if iSettle is within 1–2% of your ask and preserves an equity position, that may be “good enough” given time value.

8. Templates & Tools

Calculation template (replicate)

  • Savings* = (Old Appraised − New Appraised) × (Composite Rate)
  • Equity ratio = (Appraised Value / Benchmark Unit, e.g., per sq ft) vs. peer median (from HCAD records).

9. Real-World Examples (anonymized)

  • Market-value win with repairs: Owner documented $22,000* in foundation/roof bids and three nearby sales net of concessions; iSettle accepted a $25,000* reduction.
  • Equity-first win: In a tract with consistent builds, the owner showed a Subject/ft 9% above peer median; ARB adopted the peer median, cutting $18,000*.
  • ARB to arbitration: Owner declined a small ARB cut; binding arbitration delivered an additional $12,500* reduction after cleaner comp set. Texas Comptroller

FAQs

What if HCAD’s market value is right but my assessment is higher than neighbors’?
File an unequal appraisal protest and bring an equity grid; Texas law (42.26) provides relief if your appraisal ratio exceeds peers beyond statutory thresholds. FindLaw Codes

Can I protest if I have a homestead cap?
Yes. The cap limits annual appraised increases to 10% for homesteads, but you should still defend market value to protect future cap calculations and equity positioning. Texas Comptroller

Are property tax consultants regulated?
Yes. Paid consultants must be registered under Occupations Code Ch. 1152; ask for license number and scope of representation. Texas Statutes

When are taxes due?
Tax bills are typically due January 31 of the following year (e.g., 2025 taxes due Jan 31, 2026). The Harris County Tax Office publicizes the deadline annually. Harris County Tax Office

If I lose at ARB, is arbitration worth it?
If your evidence is strong and the delta is material, binding arbitration can be an efficient path versus litigation. Review deposits, thresholds, and refund rules on the Comptroller’s site. Texas Comptroller
