Why a Texas Property Tax Protest Doesn't Always Lower Your Bill

The short answer: In Texas, your tax bill is based on your taxable value, not your market value. If you have a homestead, the 10% homestead cap often keeps your taxable value below market value. A protest can lower the market value and still leave the bill the same if the new value is still above the cap.

It's frustrating to hear your value came down and then see the same bill. You're not missing anything. Here's what's going on.

What's the difference between market value and taxable value?

Your appraisal notice shows several numbers. Three matter here:

• Market value. What the appraisal district (CAD) thinks your home would sell for on January 1.
• Appraised value. For a homestead, this can be lower than market value because of the 10% cap.
• Taxable value. Appraised value minus your exemptions. This is the number your tax rate is applied to.

A protest argues about market value (or whether your value is fair next to similar homes). But your bill comes from taxable value. When something else is already holding taxable value down, a lower market value may not change it.

How does the 10% homestead cap affect a protest?

Under Texas Tax Code §23.23, a homestead's appraised value is limited to 110% of last year's appraised value, plus the market value of any new improvements. The CAD uses whichever is lower: that capped amount or market value. The cap starts the year after you first qualify for the homestead exemption.

So if your market value is well above your capped value, the CAD uses the capped value anyway. A protest that trims market value but leaves it above the cap won't change your appraised value, and it won't change your bill.

A hypothetical example

These numbers are made up to show how it works:

The protest lowered market value by $20,000. That's a real reduction. But $380,000 is still above the $350,000 cap. So the appraised value stays at $350,000, taxable value doesn't change, and there are no tax savings this year.

In plain terms: the cap was already doing the work. The protest had no room to help this year.

Does a lower market value matter later?

It can, a little, in some cases. The cap only applies while market value is above the capped amount. An accurate, lower market value narrows that gap. But market value is set fresh each January 1, so we wouldn't count on any future effect.

Do the over-65 and disability tax ceilings matter?

Yes. If you're 65 or older, or disabled, and have the matching homestead exemption, your school district taxes are held at a "ceiling" (Tax Code §11.26). That ceiling generally stays in place unless you add improvements, and it can come down when the state lowers school tax rates.

Counties, cities, and junior college districts can choose to adopt the same kind of ceiling (Tax Code §11.261). Not all do, so check which units on your bill have one.

The school portion is usually one of the largest parts of the bill. With a ceiling in place, a protest may only affect the smaller, non-frozen parts. Sometimes the change is tiny. Sometimes it's zero.

Why do exemptions change the result?

Each taxing unit (school district, county, city, special districts) applies its own exemptions. The school homestead exemption is large. Others may be smaller, a percentage, or not offered at all.

So the same reduction in value can produce different savings for each unit on your bill. When exemptions and a ceiling already cover most of a unit's value, a value reduction has little left to lower.

What does a protest cover, and what doesn't it?

A protest is about your property's value. Tax rates are a separate decision, set each year by your local taxing units. They're outside the protest process, so a protest can't change them in either direction.

Who decides my value in a protest?

The CAD and the Appraisal Review Board (ARB) decide. They have the final say at that level. A protest firm, or you on your own, can gather evidence and build the strongest case possible. But no one can promise the outcome.

That's why results vary, and why some protests end with a lower value but no change in taxes.

Do I pay a fee if my protest saved nothing?

With contingency pricing, the fee is based on tax savings. No savings means no fee. If you're unsure how this applies to your account, email us at admin@taxdrop.com.

Is it still worth checking my value every year?

It's worth a look. Your situation can change from year to year: market values move, the gap between market and capped value changes, and exemptions or ceilings can change. A year where a protest couldn't help doesn't mean the next year will be the same. Whether you protest again is up to you.
