Learn how to win your Harris County property protest. Discover protest rights, deadlines, evidence, and save on your property taxes.

A Harris County property protest is a way to tell the county that your home's value is too high. In 2023, most people who tried this won. They saved about $2,061 each.
Quick Facts:
Every spring, homeowners get a blue envelope. It tells you what the county thinks your home is worth. This number decides how much tax you pay. But you have the right to say that number is wrong. If you do, you can save a lot of money.

When you open that blue notice from the county, it might feel like you just have to pay what they say. But in Texas, the law says you have the right to make sure the value is fair.

In 2023, all the property in Harris County was worth a lot of money. The county uses computers to guess what your home is worth. Computers are smart, but they don't know if your roof is leaking or if your neighbor's house is much nicer than yours.
Before you start, you need to know three numbers on your notice:
| Value Type | What It Means |
|---|---|
| Market Value | What your home would sell for on January 1st. |
| Appraised Value | The value used for taxes after any limits are added. |
| Taxable Value | The final number used to figure out your tax bill. |
You can find more details on these values at the HCAD website.
Your tax bill comes from many places. This includes your school, the city, and the county. They all set their own rates.
The math is easy: (Taxable Value / 100) x Tax Rate = Your Tax Bill.
If you lower the value of your home, you lower your bill. This money goes to schools, police, and fixing roads.
If you think your home's value is too high, you are not alone. In 2023, over 529,000 people protested. The results were great:
Most mistakes happen because the county uses computers to guess values. Maybe they think your house is bigger than it is. Protesting is the only way to fix these mistakes.
You must be on time. If you miss the date, you cannot save money this year.
The big date to remember is May 15. This is the last day for most people. If you get your notice late, you have 30 days to file. Don't wait until the last minute!
You can file your protest in three ways:
Many people use the online system because it is easy. You will need the account number and the code from your blue notice.
Once you are in, you can send your protest right away. You can also see if the county offers you a lower value online. This is called iSettle.
You don't need to be an expert to fill out the form. You just need:
On the form, check the boxes for "Value is over market value" and "Value is unequal." This gives you more ways to win. If you need help with your home, see our residential tax services page.
Starting the protest is the first step. To win, you need proof. You cannot just say your taxes are too high. You have to show why the value is wrong.
There are two main ways to win:
You should ask the county for their "Evidence Package." They have to give you the data they are using for free. Look at it closely! If they compared your house to one with a pool, and you don't have a pool, you can win.
If you have a business, the rules are a bit different. See our commercial tax services for help.
This is a great way to save money. The county thinks your house is in good shape. If it is not, you need to show them. You can use:
Bring four copies of your proof to your meeting so everyone can see it.
After you file, you will have two meetings. One is a simple talk. The other is a more serious meeting.
This is a simple talk with a person from the county. You show them your photos and proof. They might offer to lower your value right then! If you like the offer, you sign it and you are done. If you don't like it, you can go to the next meeting.
Many people also use the online system to settle without leaving home. The county settles many protests this way every year.
If you don't agree at the first meeting, you go to the ARB. This is a group of three people who do not work for the county. They are like a jury.
If you think the group was wrong, you can still fight. You have 60 days to ask for more help. We can help you decide if this is a good idea. Check out our tax services for more info.
A protest lowers your home's value. But there are other ways to lower your taxes too. These are called exemptions. They are like coupons for your taxes.
The most common one is the Homestead Tax Break. It does two things:
You can ask for this at the tax office.
If you are over 65 or have a disability, you get more help:

Market value is what someone would pay to buy your house today. Appraised value is the number the county uses to figure out your taxes. If you have a tax break, the appraised value might be lower than the market value.
Yes! And you should. The county changes values every year. Even if you won last year, they might raise the value again. Protesting every year is the best way to keep your taxes low.
Usually, you lose your chance to protest for that year. It is very hard to fix this if you are late. Make sure to mark your calendar for next year!
