Is an ag exemption the same as an ag or timber number?

No, and this trips up a lot of people. The property tax ag exemption is a lower way of valuing your land, and you apply for it with your county appraisal district on Form 50-129. The ag or timber number is a separate sales tax registration from the Texas Comptroller (Form AP-228) that lets you buy some farm and ranch items without paying sales tax. Two different things, two different agencies.

How much activity do you need to qualify?

Enough to meet what your county calls its degree of intensity, which is the real level of farming or ranching the county expects for land like yours. That level is set county by county and is not a statewide number, so a figure that works one county over may not apply to your parcel. Check your county for the standard on your land. Not legal or tax advice.

What qualifies for a Texas ag exemption?

Q: What qualifies for a Texas ag exemption?

The common qualifying uses are grazing livestock, growing hay or crops, beekeeping on 5 to 20 acres, and wildlife management on land that already had the ag value. Orchards, vineyards, poultry, and some other real farm or ranch uses can count too. There is no single statewide list of exact animals or acres. Each county appraisal district sets how much activity is enough, so check your county.

A plain list of the ways Texas land earns the lower ag value, and why there is no single statewide checklist of animals or acres.

What kinds of use qualify?

The common ones are grazing livestock, growing hay or crops, beekeeping on 5 to 20 acres, and wildlife management on land that already had the ag value. There is no statewide list of exact animals or acres. Each county decides how much activity is enough, so the real question is what your county expects for your land.

First, two things people both call an ag exemption

Before the list, clear up a mix-up that sends people to the wrong office. In Texas, two different things get called an ag exemption:

The property tax ag value. This is the one most people mean. It is a lower way of valuing your land so the tax bill drops. You apply for it with your county appraisal district on Form 50-129. This page is about this one.
The ag or timber number. This is a separate sales tax registration from the Texas Comptroller (Form AP-228). It lets you buy some farm and ranch supplies without paying sales tax. It is not a property tax break, and having it does not lower your land value.

Same nickname, two different agencies. If you want the lower tax bill on the land, you want the property tax ag value below. Which form do I need?

The ways land qualifies

Land earns the ag value by being genuinely used for agriculture. These are the common routes:

Grazing livestock
Running cattle, sheep, or goats is the most common way land qualifies. Your county sets how many animals it expects for your acreage.
How many cows do you need?How many sheep or goats?
Hay and crops
Cutting hay or growing grain, row crops, orchards, or vineyards can qualify when it is a real, ongoing operation at your county level.
Beekeeping
Land of 5 to 20 acres can qualify through beekeeping. The number of hives is set by your county, not the state.
How many hives do you need?
Wildlife management
Land that already carries the ag value can keep the same low value by managing for native wildlife instead of livestock.
How wildlife management works
Horses
Keeping or riding horses for personal use is not agriculture on its own. Breeding or raising horses as a real business, or running hay and grazing on the land, is what can qualify.
Do horses qualify?
Other real farm or ranch uses
Poultry, exotic animals raised for sale, aquaculture, and similar working uses can qualify where a county recognizes them. Personal or hobby use does not.

Why there is no one checklist

People search for a list of exact numbers, so many head of cattle, so many acres, so many hives. Texas does not work that way. The kind of use that qualifies is set by state law, but how much of it is enough is set county by county, in what each county calls its degree of intensity. That is why a neighbor one county over can have a different number than you.

So treat any figure you read online as a starting point, then check the standard your county actually uses for your parcel. Not legal or tax advice, and approval is up to your county.
