Tarrant County Property Tax Protest: How to Do It Yourself
If your Tarrant County appraisal notice shows a value that seems too high, you have the right to protest it before the Appraisal Review Board/ARB. The process is free, the forms are straightforward, and most homeowners can handle it without hiring a company. This guide walks you through exactly what to do — step by step.
Who Handles Your Protest: The Tarrant Appraisal District
Property values for tax purposes in Tarrant County are set by the Tarrant Appraisal District/TAD. TAD is separate from the taxing units (cities, school districts, etc.) that actually collect your taxes — it just determines the assessed value. When you protest, you are challenging TAD's valuation, not your tax bill directly. A successful protest lowers your assessed value, which then reduces the taxable amount each of those entities uses to calculate what you owe.
The Protest Deadline — and Why It Matters
Texas law sets a firm deadline — typically May 15 or 30 days after TAD mailed your Notice of Appraised Value, whichever is later. Miss it and you lose your chance to protest that year. Confirm the exact date at tad.org before you do anything else.
Grounds for Protest: What You Can Actually Argue
You need a reason — called a ground for protest — to file. The two most common for homeowners are:
- Value over market value: TAD's appraised value is higher than what your home would realistically sell for today. You support this with recent comparable sales (comps) — similar homes nearby that sold for less.
- Unequal appraisal (equity): Your home is assessed at a higher rate relative to its actual market value than comparable properties in the same area. Texas is one of the few states where this uniformity argument alone can win a reduction.
You can check both on the same protest form — most homeowners do. TAD's online portal (iFile) lets you submit your protest electronically and often shows you comparable properties TAD used so you can see right away whether their numbers hold up.
How to File Your Protest With TAD
TAD offers three ways to file: online through iFile at tad.org, by mail using Form 50-132 (Notice of Protest), or in person at the TAD office. Online is the fastest. Once your protest is logged, TAD may send you an informal settlement offer — a proposed reduced value — before you ever sit in front of the ARB. Many protests are resolved at this informal stage.
If you reject the informal offer or don't receive one, your case goes to a formal ARB hearing. The ARB (Appraisal Review Board) is an independent panel, not TAD staff. You present your evidence, TAD presents theirs, and the board decides. Hearings typically last 15–30 minutes.
Tarrant County by the Numbers: What TAD Values and What the County Charges
These are the Comptroller's official numbers for the county — 2025 County Report of Property Value, data version January 28, 2026 — and they show the scale the appraisal district operates at.
| Measure | Tarrant County | What it means |
|---|---|---|
| Total market value | $400.0 billion | The district's full valuation of county property, exemptions not yet deducted. |
| Taxable value (General / Road & Bridge) | $296.6 billion | The base the county actually taxes after exemptions. |
| County tax rate, 2025 | $0.18620 per $100 | County portion alone; your bill adds school, city and special-district rates on top of it. |
| County levy | $0.552 billion | What that rate yields for the county across all accounts. |
What this means for your bill. On $300,000 of taxable value the county line alone runs about $559 a year ($300,000 ÷ 100 × $0.18620). Take 10% off the appraised value and that line drops by roughly $56 — and the identical reduction then applies to every other rate charged on the same value, which is where the bulk of any saving comes from. Tarrant runs one of the lowest county rates among the big metros, which makes the school-district share of your bill proportionally larger. Your own rates appear on your tax bill.
Evidence That Actually Moves the Needle
Bring printed copies of everything — the ARB does not want to scroll through your phone. Useful evidence includes:
- Recent sales of comparable homes (comps): ideally 3–5 properties in your neighborhood, similar square footage, lot size, age, and condition, that sold within the past 12 months for less than TAD's value.
- A current independent appraisal if you had one done recently (for a refinance, for example).
- Photos or repair estimates documenting condition issues TAD may not know about — foundation problems, roof damage, outdated systems.
- TAD's own comparable data from the iFile portal, if it shows inconsistency with how they valued your home versus similar ones.
A reduction depends entirely on how well your evidence lines up with the ARB's standards. Strong comps are the most reliable path to a lower value.
Common Questions About Protesting in Tarrant County
Is there a filing fee?
No. TAD charges nothing to file. Only a protest company costs you money, typically a share of what it saves.
What is the difference between the two grounds?
Market value asks what the home would sell for. Unequal appraisal asks whether comparable properties are valued lower per square foot. Texas allows a reduction on the second ground alone.
Can the value go up because I protested?
The ARB rules on the evidence before it and is not bound to your figure. In practice reductions are the common outcome, but no result is guaranteed.
How long do I have to file?
Until May 15 or 30 days from the date TAD mailed your notice, whichever falls later. Check the printed date and confirm at tad.org.
Can this be resolved without a hearing?
Usually yes. An informal offer from TAD commonly closes the matter; the ARB hearing is the fallback if you reject it.
