What You Actually Keep
On a $5,000 annual reduction (typical for a Texas home in Harris, Travis, or Collin County) at Gill, Denson's 30% residential rate:
On a smaller $1,500 reduction, Gill, Denson costs about $450 versus $49 with AppealDesk. Break-even is roughly $163 in annual savings, below that, contingency wins because there is no fee if there are no savings; above that, the flat fee saves more on every protest.
Why This Comparison Matters Right Now
Gill, Denson & Company is advertising aggressively across Google, Meta, and direct outreach in Texas heading into the 2026 protest season. Most of the ads emphasize the boutique, contingency-fee experience: file your protest, no upfront cost, they handle the hearing. That model can work, but the trade-off is the 30% residential rate (1-4 properties) on every reduction, plus an auto-renewing service agreement that resets each March 1. AppealDesk is the alternative for Texas homeowners who want professional protest evidence without giving up a third of their savings, and who prefer to file the protest themselves through the appraisal district's online portal in 10-15 minutes.
Pricing & Total Cost
Gill, Denson's residential pricing is published on their site: 30% of actual tax savings for 1-4 properties, dropping to 25% at 5 or more properties. Almost every homeowner pays the full 30%. On a $1,500 reduction, the fee is $450. On a $3,000 reduction, $900. On a $5,000 reduction (common in Harris, Travis, or Collin County), $1,500. AppealDesk charges a flat $49 regardless of the size of the reduction. The break-even point is around $163 in annual savings. Below that, Gill, Denson's contingency is cheaper because the fee is zero if there are no savings. Above $163, AppealDesk's flat $49 saves more on every protest, and the gap widens as the reduction grows. For Texas homeowners in higher-value counties where reductions of $2,000-5,000 are common, this is the entire point of the comparison.
Coverage & The Texas-Only Constraint
Gill, Denson covers all 254 Texas counties, which is genuinely strong, every county from Harris to Travis to Hidalgo to El Paso. Outside Texas, they do not operate. AppealDesk also covers all of Texas, plus the other 49 states and over 3,100 counties total. If you only own property in Texas, this point doesn't differentiate them. If you own a second home in Florida, a rental in Georgia, or you might move out of state, only AppealDesk follows you.
What You Actually Receive
With Gill, Denson, you receive the outcome: a reduced (or unchanged) appraised value at the end of the protest cycle. They file the protest, conduct informal negotiations with the appraisal district, attend the ARB hearing if needed, and handle binding arbitration or judicial appeal in the rare cases that escalate. You do not see the comparable sales they used, the evidence presented, or the back-and-forth with the appraiser. With AppealDesk, you receive a three-part packet: an evidence packet with comparable sales analysis and price-per-square-foot calculations, a county-specific filing guide tailored to your appraisal district's online portal, and a professional cover letter using Texas "protest" terminology. The packet also includes assessment ratio verification, which most Texas homeowners skip but which directly affects the evidence you present at an informal hearing.
The Filing Experience
Texas property tax protests can be filed online through almost every appraisal district's portal (HCAD for Harris County, TAD for Tarrant, DCAD for Dallas, TCAD for Travis, etc.). With AppealDesk, you upload your evidence packet to the portal and submit, the typical flow takes 10-15 minutes. If you request an informal meeting (always recommended in Texas), you present your packet and negotiate directly with the appraiser. If the informal doesn't resolve it, you go to the formal ARB hearing. AppealDesk's filing guide includes scripts and preparation guidance for both. With Gill, Denson, you sign an authorization form letting them act as your agent, complete a property questionnaire, and they handle every step from there. They explicitly discourage clients from attending the hearing, noting that "sometimes clients accidentally introduce new evidence that hurts our case." For a homeowner who wants zero involvement, this is convenient. For a homeowner who wants to understand and learn the process, it is opaque.
The Auto-Renewal Detail
Gill, Denson's service agreement auto-renews every March 1. The firm protests every property on file each year unless you instruct them otherwise. You can cancel by emailing support@gilldenson.com or using the client dashboard, but you have to remember to do it. For homeowners who want every-year representation, this is a feature: protests get filed automatically every season. For homeowners whose situation changes, sale of the property, move out of state, transition to a different service, the auto-renewal can produce surprise contingency fees on reductions you didn't actively choose. AppealDesk has no auto-renewal. Each year you decide whether to generate a new packet, with current-year comparable sales, for the current protest cycle. Your evidence is yours, not tied to a service agreement.
Success Rates & Track Record
Gill, Denson reports that more than 80% of clients received a reduction in the 2025 protest season. Their case studies cite residential savings of $5,000-$15,000 per year on higher-value properties, and substantially larger numbers on commercial and business personal property. These are strong numbers for a boutique firm. AppealDesk's success rates also vary by county, in Hays County, TX, 98.68% of protests result in reductions; across other Texas counties, success depends on assessment accuracy. The state-wide protest-friendly statutory framework benefits both services. The honest read: in Texas, a well-prepared protest with comparable sales evidence wins a reduction in most counties most of the time. The deciding factor is rarely the service, it is whether your appraisal district's notice is in fact higher than recent comparable sales support.
A Note on Boutique vs Mass-Algorithm Framing
Gill, Denson markets themselves as the alternative to "mass algorithm" property tax services, with a "custom-tailored approach" that takes more time. The implicit critique is aimed at large, automated firms. AppealDesk is not a mass-algorithm service in the traditional sense, the evidence packet uses AI-driven comparable sales analysis specific to your property, your county's assessment ratio, and your subject's sqft and year-built filters. The packet also runs through a quality gate before delivery and is cross-checked against county-specific filing rules. The model is closer to a structured analytical pipeline than either a manual boutique or a one-size-fits-all algorithm. For a homeowner choosing between them, the relevant question is not "which firm produces better evidence in the abstract" but "do I want to file the protest myself for $49 with a complete evidence packet, or do I want a firm to file and represent me for 30% of whatever I save."
Who Should Choose Gill, Denson Instead
Choose Gill, Denson if you live in Texas, you have a higher-value property where the time savings of full-service representation are worth the 30% fee, and you specifically want someone to attend the ARB hearing on your behalf. They are particularly strong for homeowners with multiple Texas properties (the rate drops to 25% at 5+), commercial owners, or business personal property cases where the analysis is more complex. If you would rather pay 30% than complete a property questionnaire, file an online protest, and potentially attend an informal meeting, Gill, Denson eliminates almost all effort on your part. If you expect a small reduction (under $200/year), Gill, Denson's contingency model also has the advantage, the fee is zero if there are no savings, whereas AppealDesk's $49 is paid upfront after a free overassessment estimate.
