Every Houston Property Tax Exemption Explained
Property tax exemptions can save Houston homeowners hundreds — or even thousands — of dollars per year. But most people don't know which ones they qualify for, or how they actually change what you owe. This guide breaks down every major exemption available in Harris County, what it does to your tax bill, and how to claim it.
General Residential Homestead Exemption
If you own and occupy your home as your primary residence on January 1, you qualify for a homestead exemption. This is the most common and most important exemption in Texas.
What it does
School district taxes: $100,000 is subtracted from your assessed value before your school tax is calculated. On a $500,000 home, you'd pay school taxes on $400,000 instead.
10% annual cap: Your assessed value for tax purposes cannot increase more than 10% per year, no matter how much HCAD raises your market value. This is huge in a rising market — if your home jumps $100K in market value, your taxable value can only go up 10% of the prior year's assessed value.
County/city: Harris County offers an additional 20% exemption on the assessed value. Some cities and special districts offer their own homestead exemptions too.
How to claim it
File Form 50-114 with the Harris County Appraisal District. You can file online at HCAD.org, by mail, or in person. Once approved, it stays on your property until you sell or move — no need to re-file each year.
Over-65 Homestead Exemption
If you're 65 or older and have a homestead exemption, you qualify for additional benefits that go beyond the standard homestead.
What it does
School district tax ceiling: Your school district tax amount is frozen at the level it was when you turned 65 (or when you acquired the property, whichever is later). This is a dollar freeze, not a value freeze — even if your assessed value goes up, your school tax stays the same.
Additional exemptions: An extra $10,000 is deducted from assessed value for school district purposes, on top of the $100,000 general homestead exemption. Many local taxing units offer additional exemptions of $25,000–$75,000 or more.
County/city taxes are NOT frozen — they still go up when assessed value increases. This is why protesting your property taxes is still extremely valuable even with an over-65 exemption.
How to claim it
File Form 50-114 with HCAD. You'll need proof of age (driver's license, birth certificate, or passport). If you already have a general homestead exemption, you can add the over-65 component.
Disability Homestead Exemption
If you receive disability benefits under the Federal Old Age, Survivors, and Disability Insurance Program (Social Security), you qualify for similar benefits to the over-65 exemption.
What it does
The disability exemption provides the same school district tax ceiling and additional exemption amounts as the over-65 exemption. You cannot claim both — if you're over 65 and disabled, you get whichever provides the greater benefit (they're usually identical).
Disabled Veteran Exemption
Veterans with a service-connected disability rated by the VA receive property tax exemptions based on their disability percentage.
| Disability Rating | Exemption Amount |
|---|---|
| 10% – 29% | $5,000 from assessed value |
| 30% – 49% | $7,500 from assessed value |
| 50% – 69% | $10,000 from assessed value |
| 70% – 100% | $12,000 from assessed value |
| 100% or unemployable | Total exemption — $0 property tax |
A veteran rated 100% disabled (or individually unemployable) pays zero property taxes. This also applies to the surviving spouse if they haven't remarried.
Surviving Spouse Exemptions
Surviving spouse of over-65: If your spouse had the over-65 exemption and passes away, you can keep the tax ceiling if you were at least 55 when they died and the property remains your homestead.
Surviving spouse of disabled veteran (100%): You keep the full exemption as long as you don't remarry and the property remains your homestead.
Surviving spouse of military member killed in action: Full property tax exemption, same rules as 100% disabled veteran.
Agricultural (1-d-1) Exemption
If your land is used primarily for agriculture, timber, or wildlife management, it can be appraised based on its productive capacity rather than market value. This typically results in dramatically lower assessed values — sometimes 90%+ lower than market value.
This is technically an "appraisal" method, not an exemption, but the effect is the same: much lower taxes. Note that there's a rollback tax if you stop agricultural use — you'd owe the difference in taxes for the prior 5 years.
How Exemptions Interact With Protesting
Here's the key insight that most homeowners miss: exemptions and protests work together, not instead of each other.
Exemptions reduce what you're taxed on. Protesting reduces the starting value that exemptions are applied to. Lower starting value + exemptions = maximum savings.
