Harris County property tax exemptions can cut thousands of dollars off your annual bill, and most homeowners qualify for more than one. The general residence homestead exemption removes $140,000 from your home’s taxable value for school district taxes and adds a 20% reduction for county taxes. Homeowners who are 65 or older, disabled, or disabled veterans stack additional exemptions on top. All of them are claimed on a single application filed with the Harris Central Appraisal District.
General Residence Homestead Exemption
Any Harris County homeowner who uses a property as a principal residence qualifies. You must own the home (directly or through a qualifying trust) and live in it, and you can only claim a homestead exemption on one property at a time. The application requires you to affirm you have no homestead exemption on any other property in or outside Texas.1State of Texas. Texas Tax Code 11.13 – Residence Homestead
The exemption pulls value off your appraisal at several taxing units:
- School districts: a mandatory $140,000 reduction in taxable value. School taxes are usually the largest line on a Harris County tax bill, so this piece produces the biggest single savings.2Texas Comptroller of Public Accounts. Property Tax Exemptions
- Harris County: a 20% exemption on appraised value, with a minimum reduction of $5,000.
- Cities, community college districts, and special districts: may offer their own optional exemptions of up to 20%, with a $5,000 minimum. Not every unit offers one, so total savings depend on where the property sits.
On a home appraised at $350,000, that’s a $140,000 cut for school taxes and $70,000 off for the county. The exemption stays in place for as long as you own and live in the home, without annual reapplication.
The 10% Appraisal Cap
Qualifying for the homestead exemption also triggers a limit on how fast your appraised value can rise. The appraisal district cannot increase the appraised value of a homestead by more than 10% per year, no matter what the market does.3Texas Comptroller of Public Accounts. Valuing Property Over time, in a rising market, this cap often saves more than the exemption dollars themselves.
The cap starts on January 1 of the year after you first qualify. Buy a house in March 2025 and file for the exemption the same year, and the 10% limit begins with the 2026 appraisal. Two things fall outside the cap: new improvements you add (a room addition, a pool), and repairs or routine maintenance are unaffected. If market value drops below the capped value, you pay tax on the lower market value.
Over-65 Exemption
Homeowners who turn 65 during or before the current tax year get more. School districts must provide an extra $60,000 exemption, which stacks on the $140,000 general amount for a combined $200,000 reduction in school taxable value.4Harris Central Appraisal District. Property Tax Exemptions for Homeowners Cities, the county, and other units may add exemptions of at least $3,000, with amounts varying by jurisdiction.
The most valuable piece is the school tax ceiling. In the first year you qualify, the dollar amount of school taxes you owe becomes a permanent cap. Your school taxes will never exceed that number, even if your home’s value rises or the district raises its rate. Adding improvements can push the ceiling higher; a drop in the district’s compressed tax rate can move it down.5State of Texas. Texas Tax Code 11.26 – Limitation of School Tax on Homesteads of Elderly or Disabled
If an over-65 homeowner dies, a surviving spouse who is at least 55 can keep the exemption and the ceiling on the same property, as long as the spouse still owns and lives in the home. The surviving spouse doesn’t need to be 65. The ceiling also transfers proportionally if you sell and buy another home in Texas, so moving doesn’t erase the benefit.
Disability Exemption
Homeowners who meet the Social Security Administration’s definition of disability get the same additional benefits as those 65 and older: an extra $60,000 off school taxable value on top of the general $140,000, plus the school tax ceiling.2Texas Comptroller of Public Accounts. Property Tax Exemptions Eligibility requires a medically determinable physical or mental impairment that prevents substantial gainful activity and is expected to last at least 12 continuous months or result in death.6Harris Central Appraisal District. Disability Homestead Exemptions Information and Requirements
If you receive Social Security disability benefits, you automatically qualify. Otherwise, you’ll need a licensed physician’s statement.
If you’re both 65 or older and disabled, you can receive both exemptions in the same year, but not from the same taxing unit.2Texas Comptroller of Public Accounts. Property Tax Exemptions In practice, you might take the over-65 exemption from the school district and the disability exemption from the county, or the other way around, whichever combination reduces your bill more.
Disabled Veteran Exemptions
Veterans with a service-connected disability rating from the Department of Veterans Affairs get a partial exemption that scales with the rating. It applies to any one property the veteran designates, not just a homestead:
- 10% to 29% disability: $5,000 off assessed value
- 30% to 49%: $7,500
- 50% to 69%: $10,000
- 70% to 100%: $12,000
These amounts are set by statute and apply across all taxing units on the designated property.7State of Texas. Texas Tax Code 11 – Taxable Property and Exemptions
Total Exemption for 100% Disabled Veterans
Veterans rated 100% disabled or classified as individually unemployable by the VA pay zero property tax on their residence homestead. The entire appraised value is exempt.8State of Texas. Texas Tax Code 11.131 – Residence Homestead of 100 Percent or Totally Disabled Veteran On a $400,000 home in Harris County, that can be $10,000 or more a year.
If a 100% disabled veteran dies, a surviving spouse keeps the total exemption on the same home, provided the spouse doesn’t remarry and continues to live there. If the surviving spouse later moves, the exemption transfers to the new homestead in a dollar amount equal to what was exempt on the former one.
How to Apply
All residence homestead exemptions in Harris County are claimed on Form 50-114, the Application for Residential Homestead Exemption, available from the Harris Central Appraisal District website or the Texas Comptroller.9Texas Comptroller of Public Accounts. Residence Homestead Exemption Application The single form covers the general homestead, over-65, disability, and disabled veteran exemptions. You’ll need your 13-digit property account number, which appears on your notice of appraised value or tax statement.10Harris Central Appraisal District. Search Help
Required Documents
Every applicant must submit a copy of a Texas driver’s license or state-issued ID showing an address that matches the property. Texas law bars the chief appraiser from granting the exemption when the addresses don’t match, so update your ID before applying if you’ve recently moved. Active-duty military and their spouses can request a waiver on the form itself.9Texas Comptroller of Public Accounts. Residence Homestead Exemption Application
Additional documents depend on which exemption you claim:
- Over-65: proof of age, usually the birth date on your driver’s license or state ID; a birth certificate works if the ID doesn’t show it.
- Disability: a Social Security benefit verification letter confirming disability status, or a physician’s statement if you don’t receive SSA disability benefits.11Social Security Administration. Get Benefit Verification Letter
- Partial disabled veteran: a VA disability rating letter showing your service-connected percentage.
- 100% disabled veteran: a VA benefit summary letter confirming 100% disability compensation or individual unemployability.12Veterans Affairs. Download VA Benefit Letters
Where to File
The Harris Central Appraisal District accepts applications through its online portal at owners.hcad.org, where you can upload the form and supporting documents and receive a filing confirmation. You can also mail a signed paper application to Harris Central Appraisal District, 13013 Northwest Freeway, Houston, Texas 77040.13Harris Central Appraisal District. Contact HCAD Paper filings generally take longer to process.
Once approved, the exemption applies to your tax bills automatically. You don’t reapply each year unless your ownership or residency changes.
Filing Deadlines
The standard deadline is April 30 of the tax year for which you want the exemption.14Texas Comptroller of Public Accounts. Residence Homestead Exemptions Missing it isn’t fatal. Texas law allows a late homestead application up to two years after the delinquency date for the taxes on the property.15State of Texas. Texas Tax Code 11.431 – Late Application for Homestead Exemption If a late application is approved after you’ve already paid the taxes, the tax collector must refund the amount attributable to the exemption within 60 days, without a separate request.
Mid-Year Purchases
Buy after January 1 and you may still qualify for a prorated general homestead exemption for the remainder of the tax year. The previous owner must not have already claimed a homestead exemption on the property for that year, and you must own and occupy it as your principal residence.2Texas Comptroller of Public Accounts. Property Tax Exemptions The 10% appraisal cap won’t kick in until January 1 of the following year, even if the prorated exemption applies mid-year.
Effect on Your Mortgage Payment
If your property taxes are paid through a mortgage escrow account, an approved exemption eventually produces an escrow surplus. Under federal law, your servicer must run an annual escrow analysis and refund any surplus of $50 or more within 30 days of that analysis. Smaller surpluses may be credited to next year’s escrow.
Servicers run analyses on fixed schedules, so an exemption approved mid-cycle may not show up in your monthly payment right away. To speed things up, contact your servicer after the first tax bill reflecting the exemption is issued and ask for an off-cycle escrow analysis, sending a copy of the new bill with the request. Without that step, the tax savings can take months to reach your monthly payment even though they are already in effect on the county’s side.
