A Houston Homeowner’s Guide to the Homestead Exemption in 2026

By Shian Munro, Realtor® | May 2026

If you’ve recently bought a home in Houston, Katy, Sugar Land or the surrounding area, there’s one piece of paperwork you shouldn’t overlook: your Texas homestead exemption.

This isn’t a protest or an appeal. Instead, it’s an exemption for the home you own and live in as your primary residence. Most importantly, it can reduce the value used to calculate your property taxes.

I talk about this with every buyer I work with. It’s very easy to close on a home, move in and assume someone has already handled it. They haven’t. You need to apply.

Didn’t file straight after closing? Don’t panic. You may still be able to file late and recover taxes you overpaid.

What does the Texas homestead exemption do?

The exemption offers two important benefits:

It reduces the taxable value of your home for certain taxing entities.
It helps limit how quickly your appraised value can increase over time.

For 2026, qualifying Texas homeowners receive a $140,000 school district exemption on their primary residence. Texas voters approved this increase in November 2025. The previous exemption was $100,000.

So, if your home is appraised at $650,000, the school district calculates taxes on $510,000 rather than the full $650,000.

In addition, your location may qualify you for other exemptions. Your county, city, MUD or another taxing entity may offer them. Because these vary, always check the exemptions shown on your individual property record.

The 10% appraisal cap: the part buyers often don’t hear about

However, the exemption isn’t only about this year’s bill. For many homeowners, its long-term value matters even more.

Once your home qualifies for the homestead exemption in consecutive years, the appraisal cap generally limits increases in its taxable appraised value to 10% per year. This can help, even when the market value increases by more.

As a result, this matters in areas where property values can move quickly.

Imagine you buy a home for $800,000, then values in the area rise sharply the following year. The appraisal district may show a higher market value. Once the cap applies, however, it may limit the taxable appraised value.

There are two points buyers need to understand:

The cap won’t protect you from a market-value adjustment immediately after you buy the home.
The previous owner’s cap won’t transfer to you. You’ll need to apply for your own exemption.

Because of this, a buyer’s first full tax assessment can come as a surprise. It happens most often when the previous owner lived in the home for many years and benefited from a capped value.

How do you file in Harris County?

If your home is in Harris County, you’ll apply through the Harris Central Appraisal District, generally known as HCAD.

Fortunately, there’s no fee to file. You can apply online through HCAD or complete the residence homestead exemption application form.

You’ll generally need:

The property address and HCAD account number
A Texas driver’s licence or state ID showing the property address
Your closing or occupancy date
Confirmation that the home is your primary residence

Your Texas ID needs to show the property address. If it still shows your old address, update it before you file.

Can you file after closing?

Yes. Once you own and occupy the property as your primary residence, you can apply. You don’t need to wait until the following January.

In real life, that means: close on your home, move in, update your Texas ID and submit the application.

What if you missed the April deadline?

The usual filing deadline is April 30. However, missing it doesn’t always mean you’ve missed out.

For a general homestead exemption, you can usually file a late application up to two years after the taxes became delinquent for that tax year. If the appraisal district approves it and you overpaid, you may receive a refund.

So, did you buy a home in 2024 or 2025 and never file? It’s worth checking now.

What about Fort Bend, Montgomery or Waller County?

The homestead exemption applies across Texas. The only difference is that you file with the appraisal district for the county where your home is located.

Fort Bend County: Fort Bend Central Appraisal District
Montgomery County: Montgomery Central Appraisal District
Waller County: Waller County Appraisal District

Live in a master-planned community with a MUD? Check whether that district offers its own exemption too. MUD exemptions can vary, even between nearby communities.

A few quick questions I’m often asked

How much could the exemption save me?

That depends on your home’s value, location and taxing entities. For example, the school district exemption removes $140,000 from the value used for school district taxes. Local exemptions may reduce other parts of your bill as well.

Do I need to file every year?

Usually, no. Once your appraisal district approves the exemption, it generally stays in place. You may need to reapply if the district requests it or your eligibility changes.

Does it apply to a second home or investment property?

No. The general residence homestead exemption applies to the home you own and occupy as your primary residence.

Is this the same as protesting my property value?

No. They are two separate things. You may qualify for the exemption and still protest your appraised value if you believe it’s too high.

My advice to Houston-area homeowners

Texas property taxes can be a shock, especially for buyers moving from another state or another country.

The homestead exemption won’t remove your property taxes. It can, however, reduce your bill and help protect you from sharper increases over time.

If you’ve bought your primary home and haven’t filed yet, add it to your list. It’s free. It doesn’t take long. And it’s far better to handle it now than find out later you’ve paid more than necessary.

When I help a client buy in the Houston area, my role doesn’t end at the closing table. Property taxes, exemptions, MUD rates and future costs all form part of making a confident move.

Finally, Texas is a non-disclosure state, so the information online doesn’t always tell the full story. Through HAR MLS, I can help clients compare a home with relevant closed sales in the area. We can also talk through the tax considerations that come with ownership.
