If you own property in Texas, you have probably heard two terms that sound similar but mean very different things: market value and appraised value. Understanding the difference is one of the most important steps in lowering your property taxes.
If you are trying to reduce your property tax bill, the distinction matters. While the tax bill is based on the appraised value, market value is often one of the strongest tools you can use to challenge an unfair assessment. For a broader overview of the process, visit our Property Tax Appeal Texas page.
Your property taxes are based on the appraisal district’s appraised value, but market value evidence can help you protest and lower that number.
Market value is the amount a willing buyer would pay and a willing seller would accept under normal market conditions. It reflects what your property is actually worth in the current real estate market.
Factors that can affect market value include:
Market value is especially important if you are buying, selling, or refinancing. But in the property tax context, its real importance is that it can serve as evidence in a protest when your tax value is too high.
Appraised value is the taxable value assigned by your county appraisal district, such as the Harris County Appraisal District. This is the number used to calculate your property taxes.
Key things to know about appraised value:
That is why many Texas property owners end up paying taxes based on inflated numbers unless they take action.
When it comes to your tax bill, the appraised value is the number that directly matters because it is the value used for taxation. But when it comes to reducing that tax bill, market value often becomes the evidence that matters most.
In other words, your taxes are based on appraised value, but your protest is often supported by market value data. If you want to understand how that works in practice, read our guide on how to protest property taxes and win in Texas.
One of the most effective ways to protest an assessment is to show that your property’s true market value is lower than the appraisal district’s number.
You may be able to support your case with:
The stronger your market-value evidence, the better your chance of reducing the appraised value and, in turn, your property taxes.
Even if the appraisal district says your value is supported, that does not mean it is correct. Mass appraisal models often overlook details that matter to your specific property.
Lowering value through a protest is one path to reducing taxes, but it is not the only one. Some owners may also qualify for exemptions that directly reduce taxable value.
Common exemptions include:
These can reduce your taxable burden even if the appraised value itself does not change.
In some cases, the issue is not only market value. Your property may also be assessed higher than similar nearby properties. That can create a separate basis for protest under an unequal appraisal theory.
To learn more, see our article on what an unequal appraisal means in Texas property taxes.
Even the best evidence will not help if you miss the filing deadline. Texas property tax protests are time-sensitive, and missing the deadline can mean losing your right to challenge the value for that year.
