Harris County Homestead Exemption 2026: A Kingwood Filing Guide

What the homestead exemption actually does

A residence homestead exemption removes part of your home's value from taxation. It does not take dollars off your tax bill directly. According to the Texas Comptroller's property tax exemptions page, Texas school districts must exempt $140,000 of a qualifying residence homestead's value from school taxes.

The Comptroller gives a simple example: if your home is appraised at $300,000 and you qualify for the $140,000 school exemption, you pay school taxes as if the home were worth $160,000. Your actual savings depend on your school district's tax rate, any value limits on your account, and the other exemptions you qualify for. That is why no one can promise you a specific dollar saving before the appraisal district and the taxing units have done their work.

The amounts at a glance

These are the exemption amounts the Comptroller lists for a qualifying residence homestead as of October 2026. Each one reduces taxable value for the taxing units it applies to.

Amounts from the Texas Comptroller's Property Tax Exemptions page, opened October 13, 2026. Local option exemptions vary by city, county, school district and special district, so check what applies to your specific address.

The Harris County layer. HCAD's property tax exemptions for homeowners page says Harris County offers a 20% optional homestead exemption. HCAD's example: a $100,000 home is taxed by the county as if it were worth $80,000. Cities, MUDs and other units on your account decide their own optional exemptions, so two Kingwood homes a few streets apart can end up with different taxable values. Not sure which county an address falls in? Start with which county Kingwood, TX is in, because the county decides which appraisal district and which county exemption apply.

What changed in 2025

If you remember a smaller school exemption, you are not imagining it. In 2025 the Texas Legislature passed two bills that raised it:

• Senate Bill 4 raised the general school district homestead exemption from $100,000 to $140,000. The enrolled bill says the change applies to tax years beginning on or after January 1, 2025, and that it took effect only if voters approved the matching constitutional amendment.
• Senate Bill 23 raised the additional school exemption for homeowners who are 65 or older or disabled from $10,000 to $60,000, with the same kind of voter-approval condition.

The Comptroller's January 2026 Property Tax Today newsletter confirms that Texas voters approved both increases on November 4, 2025. Put together, a qualifying owner who is 65 or older can have $200,000 of home value exempt from school district taxes before any local option exemption.

Who qualifies

The Comptroller lists three core requirements for the general residence homestead exemption:

• You have an ownership interest in the home.
• You live in it as your principal residence.
• You do not claim a homestead exemption on another home, in Texas or anywhere else.

The chief appraiser at the appraisal district decides whether a property qualifies. Real estate agents, lenders and sellers cannot make that decision for you.

Bought after January 1? You do not have to wait a full year. The Comptroller explains that if you acquire the home after January 1, you may receive the general homestead exemption for the applicable portion of that tax year once you qualify, as long as the previous owner did not already receive the same exemption for that year. The Montgomery Central Appraisal District describes this as a pro-rated exemption on its home page.

Age 65 or older, disability and veterans

If you are 65 or older, or you meet the disability definition used for Social Security disability insurance benefits, school districts must give you an additional $60,000 exemption on top of the general $140,000. The Comptroller notes a few details that often surprise people:

• Disability benefits from other programs do not automatically qualify you, and the appraisal district may ask for supporting documents.
• A surviving spouse who is 55 or older may be able to keep a deceased spouse's age 65 exemption if they continue living in the home.
• If you are both 65 or older and disabled, you can receive both exemptions in the same year, but not from the same taxing unit.

Disabled veterans and certain surviving spouses have separate exemptions based on disability rating, some of them partial and some total. The Comptroller page lists each one with its application form, and your appraisal district can confirm which applies to you.

Timing works differently for these exemptions. HCAD says the late-filing deadline for the age 65 or disability exemption is one year after the date you qualified: one year after you buy and move into a new home, until your 66th birthday if you just turned 65, or one year from the date you became disabled. For a disability claim, MCAD asks for documentation such as a Social Security disability determination or a physician's statement.

Harris County homeowners who are 65 or older or disabled also have payment options at the county tax office. The Harris County Tax Office tax breaks page describes a quarter payment plan that splits current taxes into four installments without penalty or interest when you send a written request and at least 25% of the taxes by January 31. It also describes a tax deferral affidavit, filed with HCAD, that lets you postpone paying delinquent taxes on the homestead; deferred taxes accrue 5% annual interest and come due 180 days after you stop owning or living in the home.

How to file for the Harris County homestead exemption

You file with the appraisal district for the county where the home sits, not with your school district or city. The Comptroller's general deadline for exemption applications is before May 1. HCAD says it accepts regular applications from January 1 through April 30, does not accept early applications, and can process an application postmarked by April 30 before fall tax statements go out. In the Kingwood and Lake Houston area, that means one of two offices depending on the address:

1. Find your county and account. Search the address on the appraisal district site. Harris Central Appraisal District explains that every property in a county is appraised by that county's district, even if the school district or utility district crosses the county line.
2. Get your ID in order. The Harris County Tax Office says the application needs a valid Texas driver's license showing the homestead address, or a state-issued photo ID if you do not have a license. Update your license address after you move in so it matches the home.
3. Harris County homes (HCAD). HCAD's homestead filing page says you can file the residence homestead application through its HCAD Info and Exemptions mobile app. Have your date of occupancy and your Texas driver's license ready. HCAD's exemption assistance page lists phone help, in-person help at 13013 Northwest Freeway, and 2026 assistance sessions from April 27 to April 30, and it calls April 30 a soft deadline for several exemption types.
4. Montgomery County homes (MCAD). The Montgomery Central Appraisal District home page has a "File Your Exemption" link to its online exemptions portal. MCAD's homestead exemptions page says you can also apply by mail or at its office at 109 Gladstell in Conroe, that it acts on applications within 90 days, and that if you do not qualify you will be offered a chance to protest the decision.
5. Paper option. The statewide form is Form 50-114, Application for Residence Homestead Exemption, linked from the Comptroller's exemptions page.
6. Split parcels. HCAD notes that if a county line runs through your property, you receive value notices from both counties and must file the homestead application with both.
7. Follow up. Check your account online a few weeks after filing to confirm the exemption shows. Then ask your lender whether your escrow will be reviewed once the new taxable value appears.

Missed April 30? You can usually still file. HCAD says a late general homestead application is accepted up to two years after the date taxes become delinquent for that year, which is usually February 1 of the following year. Filing late is far better than skipping a year you qualified for.

Keep your mailing address current. HCAD mails a postcard each January to confirm occupancy. If the postcard comes back undeliverable, HCAD removes the exemption and you have to apply again.

The 10% homestead cap and the over-65 tax ceiling

The exemption is only part of what a homestead gets you. Two other protections show up on your account once it is approved:

• The 10% homestead cap. HCAD explains that the cap starts in the second year you have the homestead exemption. After that, your appraised value for the year cannot exceed the lesser of this year's market value or last year's appraised value plus 10%, plus the value of any new improvements. It helps most in years when home values climb quickly.
• The school tax ceiling at 65 or with a disability. HCAD says that once you qualify, your school taxes will not increase unless you make improvements to the home. MCAD describes the same kind of ceiling for the disability exemption and notes that an owner who buys or moves into a different Texas home may be able to transfer the same percentage of tax paid to the new homestead, which it calls a ceiling transfer. Ask your appraisal district how this works before you move.

Both protections belong to the owner who earned them. That is why the next section matters if you are buying.

What buyers should look at before an offer

The seller's exemption does not transfer to you. Their tax bill shows what the home cost them, with their exemptions applied. Your bill can be different, especially if the seller had the age 65 exemption or lived in the home for many years. HCAD warns that a buyer of a capped home may see a large increase the year after purchase, because the cap takes effect only in the second year of ownership.

At closing, taxes for the year are prorated between buyer and seller based on estimates; HCAD notes this does not change the actual tax owed on the property. You can see how that proration fits with the rest of your costs in our breakdown of closing costs in Texas for Houston buyers and sellers.

Before you write an offer, ask for or look up:

• The current appraised value and which exemptions are on the account today.
• Every taxing unit on the account, including any municipal utility district. Check MUD taxes in Kingwood and Atascocita by address.
• Your lender's estimate of taxes and insurance in the monthly payment, and how they handle the first year's escrow.

The exemption does not change the price, your insurance, HOA dues or flood risk. Compare homes on total monthly cost, not on list price alone. If you are shopping for homes in Kingwood, TX or elsewhere around Lake Houston, Peaches can help you gather these numbers for each home on your shortlist before you decide where to offer.

After you close, watch for mail from the appraisal district. HCAD says that early each year it cancels exemptions on sold properties as of January 1 and mails the new owner an application. Confirm the ownership change shows on the account and file on time.

What sellers should prepare

Buyers will ask about taxes early. You cannot promise a buyer's future exemption, but you can make the conversation easier:

• Your most recent tax statement and the exemptions currently on the account.
• Any MUD, HOA or other district charges tied to the property.
• A note that the buyer must apply for their own exemption with the appraisal district after closing.

If you are 65 or older and planning to sell and buy again nearby, ask the appraisal district how your exemptions will apply on the new home before you set a moving date. HCAD explains that if an over-65 or disabled seller claims an exemption on a different homestead in the same year, taxes on the home being sold are prorated, which raises them. If the buyer also qualifies, the buyer can apply in their own right to avoid that proration.

After you file: your appraisal notice

The exemption shows up on your annual notice of appraised value. When it arrives, check that the homestead and any age 65 or disability exemptions are listed and that the property details are right. If something is wrong, the protest window is short. Before your deadline, walk through our Harris County property tax protest and appraisal notice checklist for what to check and how to protest with HCAD or MCAD. MCAD notes that a denied exemption can also be protested.
