How to Protest Property Taxes in Tarrant County / Fort Worth (2026 Guide)

The Tarrant County deadline

The Tarrant Appraisal District (TAD) mails your notice of appraised value in spring. From the date on that notice, you have until May 15, 2026 (or 30 days after the notice date, whichever is later) to file a protest. Miss it and your 2026 value is locked for the year, except in the specific late-protest situations allowed under Texas Tax Code 25.25.

How over-assessed Fort Worth really is

This is the headline for Tarrant. Running every analyzed Tarrant County home through the same matched-comps method the calculator uses on the live site, 227,312 homes came back over-assessed, about 38.4% of those analyzed. That is the highest over-assessment share of any Texas metro we track. Nearly two in five Fort Worth and Arlington homeowners are carrying a value above what comparable nearby properties support.

At Tarrant's 2.10% effective tax rate, that gap is expensive. A reduction protects real money every year you hold the lower value.

Step 1: Look up your assessment

Go to tad.org and search your property. Note two things:

• Your 2026 appraised value.
• How much it jumped from 2025.

A double-digit increase is a flag worth investigating. So is any value higher than what your home would realistically sell for today in Fort Worth, Arlington, Grand Prairie, Mansfield, or wherever you are in the county.

Step 2: Decide your grounds

Almost every successful residential protest in Tarrant County rests on one of two arguments, both written into the Texas Tax Code:

1. Market value too high (Texas Tax Code §41.41(a)(1) and §23.01). Your assessed value is above your home's actual market value. Evidence: recent arm's-length sales of similar homes nearby.
2. Unequal appraisal (Texas Tax Code §41.43(b)(3)). Comparable homes near you are assessed for less than yours per square foot. Evidence: a list of similar nearby properties assessed lower than your home.

The unequal-appraisal argument wins more often than people expect, because appraisal districts mass-appraise and routinely assess similar homes inconsistently. With nearly 40% of the county over-assessed, the comparable data is frequently on the homeowner's side here.

Step 3: Pull your comps

This is the whole game. You want five or more comparable properties, similar in size, age, and neighborhood, that are assessed lower than your home. Keep the evidence concise and focused on five to seven close comps rather than a sprawling list. Print or save the TAD record for each one (square footage within about 15%, year built within about 10 years, matching bed/bath, same part of town).

Finding and formatting clean comps by hand is the slow, tedious part. Our free calculator pulls your Tarrant County comps automatically and shows whether you are actually over-assessed before you spend a dollar. Run your Fort Worth or Arlington address and see the comps in about 30 seconds. If you would rather not build the packet yourself, the $99 flat packet pre-fills the iFile-ready format for you, one time, and you keep 100% of whatever you save.

Step 4: File the protest

File online through TAD Connect, TAD's online protest portal, or mail Form 50-132 (Notice of Protest) before the deadline. State BOTH grounds, market value and unequal appraisal, since they are independent legal arguments. Online filing is faster and gives you instant confirmation.

Step 5: Work the informal first

Before any formal hearing, TAD offers an informal review with an appraiser. Bring your concise set of comps. Tarrant typically grants value reductions on over-assessed homes in informal review when the evidence is tight. Be polite, lead with your comparable evidence, and ask for a specific number.

If the informal does not get you there, you can take it to the Appraisal Review Board (ARB) for a formal hearing. Same evidence, more structured setting.

What to expect

With Tarrant's unusually high over-assessment rate, a large number of homeowners who protest with solid comps get a reduction. Even a modest cut compounds, because a lower assessed value this year becomes the starting point for next year. The biggest mistake is not protesting at all and paying the full over-assessment by default.

Start by checking whether your Fort Worth or Arlington home is over-assessed. With nearly 40% of the county over-assessed, the odds you have a case are better here than almost anywhere in Texas. File before May 15.
