What happens to ag valuation when land sells
Based on the Texas Comptroller’s agricultural appraisal manual, Form 50-129, and H.B. 1244. Your appraisal district decides how the rules apply to a specific parcel.

| Situation at or after the sale | What happens to the ag valuation | Rollback tax risk |
|---|---|---|
| Buyer keeps materially the same use, run by the same individuals (2026 rule) | Ownership is not treated as changed; a late application has no 10% penalty if filed by the later of the tax delinquency date or one year after the transfer | None from the sale itself |
| Buyer keeps farming or ranching, but with a different operator | Buyer files a new Form 50-129 before May 1; a late filing before the review board approves records carries a 10% penalty | None from the sale itself |
| Land passes to the owner’s surviving spouse | Not a change in ownership; the spouse gives the district proof of the death | None from the transfer |
| Buyer builds, subdivides, or stops the ag use | Valuation ends on the part that changed | Three prior years of tax difference on that part; no interest unless the bill goes delinquent |
| Land is under the older 1-d appraisal | Owner must reapply every year and must farm as a primary occupation | The sale itself triggers a rollback, plus interest of 1% per month |
| Land is in wildlife management use | Same ownership rules; a new owner’s application includes a wildlife management plan | Same as other 1-d-1 land; a tract made smaller must meet a minimum acreage |
Does the Texas ag exemption transfer when land is sold?
The land’s qualifying history transfers, but the approval usually does not. A new owner generally has to file a new application with the county appraisal district to keep the lower valuation. Two exceptions, covered below, let the valuation continue without a new filing.
Once a 1-d-1 application is approved, the land keeps its special appraisal each year without a new application. That changes when ownership changes, when the land stops qualifying, or when the chief appraiser asks for a new application. A sale is a change in ownership, so the buyer’s file starts with Form 50-129 unless an exception applies.
The history works differently. The Texas Parks and Wildlife Department explains that the seven-year qualifying cycle applies only to the land, not the landowner, and does not start over with a new owner. A buyer who keeps the land in qualifying use does not need to build five new years of history. They need to file on time and keep the use going.
“Ag exemption” is a nickname. The Comptroller describes it as appraisal based on the land’s capacity to produce agricultural products instead of market value. It covers the land, fences, and certain appurtenances, not improvements such as a house, and not equipment.

What does land need to qualify for ag valuation in Texas?
Under the open-space law, land must be devoted principally to agricultural use to the degree of intensity generally accepted in the area. It must also have been in agricultural use or timber production for five of the preceding seven years. The county appraisal district applies both tests.
There is no statewide minimum or maximum acreage, except for beekeeping. The Comptroller’s manual says land used for bees must be at least 5 and no more than 20 acres. Chief appraisers may set size guidelines tied to the local farm economy, but they cannot fix a totally arbitrary limit. The manual also notes that in many cases, smaller tracts do not qualify.
Qualifying uses include growing crops, raising livestock, orchards, beekeeping, and wildlife management on land that already qualified. The manual gives examples of what is not enough by itself, such as tethering a cow, keeping a chicken coop, or raising a small pen of goats. Ask your appraisal district for its written intensity standards before you rely on a number from a listing.

Does the buyer have to reapply for ag valuation?
Usually yes, with two exceptions. House Bill 1244 took effect January 1, 2026. Under it, ownership is not considered to have changed if the new owner uses the land in materially the same way the former owner did in the preceding tax year, and that use is overseen or conducted by the same individuals.
That can matter when, for example, the same rancher keeps running the same grazing operation after the sale. Ask the appraisal district how it applies the test to your sale. The Comptroller’s current Form 50-129 now asks this question directly, and owners who answer yes complete only the parts that changed or that the chief appraiser requests.
The same law added a late filing window. If the land had open-space appraisal the prior year and both conditions are met, the chief appraiser must accept an application filed by the later of the tax delinquency date for that year or the first anniversary of the transfer. The usual 10 percent late penalty does not apply to it. The older exception still stands too: land passing to the owner’s surviving spouse is not treated as a change in ownership.
Every other buyer needs a new, timely application. Form 50-129 must be filed before May 1, meaning filed or postmarked by April 30. For good cause, the chief appraiser may extend that deadline by up to 60 days. A late application can still be filed before the appraisal review board approves the records, usually in July, with a penalty of 10 percent of the tax difference. After that, the land is ineligible for that year.

Does selling ag land trigger rollback taxes in Texas?
Not under the common 1-d-1 open-space appraisal. The Comptroller’s manual says plainly that selling the property does not trigger the 1-d-1 rollback. The rollback is triggered when the owner ends agricultural operations or moves the land to a non-agricultural use.
The older 1-d appraisal works differently. It is limited to individuals whose primary occupation and source of income is agriculture, it must be renewed every year, and selling 1-d land does trigger a rollback. That bill covers three years plus interest at 1 percent per month. Check your notice of appraised value to see which type your land has.
For 1-d-1 land, the rollback equals the difference between the taxes paid in the three years before the change and the taxes that would have been paid at market value. A 2021 law, HB 3833, removed interest from these bills. Penalty and interest apply only if the rollback bill becomes delinquent.
If only part of the land changes use, the rollback applies only to that part. A sale of land for right-of-way and a condemnation are among the listed exceptions.

Who pays the rollback if the buyer changes the land’s use?
Under Texas law, the person who holds title on the date the use changes is personally liable. A tax lien also attaches to the land on that date, and it can be foreclosed no matter who is liable. Tax certificates for land with agricultural appraisal must note the special appraisal and state that the land may be subject to additional taxes.
The contract usually settles the split. Paragraph 13B of the Texas Real Estate Commission’s Unimproved Property Contract puts assessments caused by the sale or the buyer’s use after closing on the buyer. Assessments caused by the seller’s use or change in use before closing stay with the seller, and that obligation survives closing. Other contract forms may word this differently, so read the clause you sign.
Disputes tend to arise when a sale and a change in use happen close together. The Comptroller’s manual cites a Dallas appeals court case over exactly that. A dated record of when the ag use stopped, if it did, helps avoid an argument later.
A buyer who wants a homesite is a common case. Claiming the land as a residence homestead does not by itself trigger a rollback. If the owner builds a homestead on former 1-d-1 land, the manual says they avoid the rollback only while they keep living there; in effect, they need to occupy the house for three years. Owners must also tell the chief appraiser in writing by April 30 after use or eligibility changes, or face a 10 percent penalty.

Does a wildlife exemption transfer with the land?
It follows the same ownership rules as other 1-d-1 land, because wildlife management is a qualifying agricultural use. The added hurdles are the management plan and, when land is divided, the acreage.
In most cases, only land that was appraised as agricultural land or timberland in the year before can switch to wildlife management. The owner must actively use the land in at least three of seven ways: habitat control, erosion control, predator control, supplemental water, supplemental food, shelters, and census counts. A wildlife application must include a wildlife management plan. Appraisal districts may require the Texas Parks and Wildlife Department form but cannot require any other form.
Acreage matters when a tract is split. TPWD says there is no minimum acreage for most wildlife properties, but land reduced in size since the previous tax year must meet a minimum set by ecoregion. In the Blackland Prairie, for example, the chief appraiser can set a minimum between 12.5 and 16.7 acres. Selling part of a wildlife-valued tract can leave a piece too small to keep the valuation.

What should a seller gather before selling ag-valued land?
Pull the paperwork that shows the valuation type and the actual use. It helps buyers price the tax side of the deal, and it gives the next owner what Form 50-129 asks for.
If the buyer plans to keep the same operation with the same people, say so in writing so the 2026 rule can be considered. If the buyer plans to build, divide, or stop the ag use, agree in the contract who pays any rollback. Talk with a Texas real estate attorney or CPA before relying on a number for your parcel.

Frequently asked questions
Does the ag exemption transfer to a new owner in Texas?
The land’s use history transfers, but the approval usually does not, so a new owner generally files Form 50-129. Since January 1, 2026, a buyer using the land in materially the same way, run by the same individuals, is not treated as a change in ownership.
What is the deadline to apply for ag valuation after buying land?
The application is due before May 1 of the tax year. Late applications are accepted until the appraisal review board approves the records, usually in July, with a 10 percent penalty unless an exception applies.
Does selling land with an ag exemption trigger rollback taxes?
Not for 1-d-1 open-space land. The rollback follows a change in use, not the sale. Land under the older 1-d appraisal is different: selling it triggers a rollback of three years of taxes plus interest.
Who pays rollback taxes after a land sale?
The owner on the date the use changes is personally liable, and a lien attaches to the land. The TREC Unimproved Property Contract puts rollbacks caused by the sale or the buyer’s use after closing on the buyer.
How many acres do you need for an ag exemption in Texas?
Texas sets no statewide minimum except for beekeeping, which requires 5 to 20 acres. Each appraisal district sets intensity standards for its area, and in many cases smaller tracts do not qualify.
Does a wildlife exemption transfer with the land?
The same ownership rules apply, and a new application includes a wildlife management plan. If the tract was made smaller since the prior tax year, it must meet the district’s minimum acreage for wildlife use.
