How to Fill Out and File Texas Form 50-129: Sections and Deadlines

Texas Form 50-129 is the application for 1-d-1 open-space agricultural use appraisal, which lets qualifying land be taxed on its agricultural productivity value instead of market value. File it with the chief appraiser of the county where your property sits, by May 1 of the tax year you want the appraisal to apply.¹ Once approved, you do not reapply each year unless ownership changes or the land stops qualifying.²

Make Sure 50-129 Is the Right Form

Texas has two agricultural appraisal programs. Form 50-129 covers the 1-d-1 open-space program under Tax Code Chapter 23, Subchapter D, which is what most landowners want. The older 1-d program under Subchapter C uses Form 50-165 and is limited to natural persons whose primary occupation and primary income source is agriculture.³ The 1-d-1 form has no income test or occupation requirement, and individuals, corporations, partnerships, and other entities can all apply. Everything below is about 50-129.

Confirm Your Land Qualifies Before You Apply

Your land qualifies for open-space appraisal only if two things are true: it is currently devoted principally to agricultural use at the degree of intensity generally accepted in the area, and it has been devoted principally to agricultural use or timber production for at least five of the preceding seven years.⁴ A year or two of non-agricultural use in the seven-year window will not necessarily disqualify you.

Qualifying agricultural uses include cultivating crops for food, feed, seed, or fiber; floriculture, viticulture, and horticulture; raising or keeping livestock; raising exotic animals for commercial products; beekeeping on tracts of 5 to 20 acres; participating in a governmental cover-crop or set-aside program on non-residential land; leaving land idle as part of a normal crop or livestock rotation; and active wildlife management.⁴

Degree of Intensity

Owning land and keeping a few animals is not enough. Your operation has to match the level of activity that is typical for the area, and each county appraisal district sets its own intensity standards — stocking rates, crop yields, and similar measures. Call your county appraisal district before you file and ask for their intensity guidelines for your type of operation. Common failure points include too few animals for the acreage, tiny “hobby” tracts that could not realistically produce agricultural income, and animals kept for recreation. FFA and 4-H projects alone do not qualify.

Wildlife Management Has an Extra Condition

Wildlife management qualifies for 1-d-1 appraisal, but the land must already have been appraised as open-space or timberland when the wildlife-management use began. You cannot go straight from non-agricultural use to wildlife management. You also have to use at least three of seven recognized practices: habitat control, erosion control, predator control, supplemental water, supplemental food, shelters, and census counts.⁴ A wildlife management plan on the Texas Parks and Wildlife Department form goes in as an attachment.¹

Filling Out the Seven Sections

Download the form from the Texas Comptroller’s website or pick one up at your county appraisal district office.³ It has seven sections, and not all apply to every applicant.

Section 1: Property Owner

Owner’s name, physical address, phone, and email. Check the box for owner type (individual, corporation, partnership, or other).

Section 2: Authorized Representative

Fill this in only if someone other than the owner is filing. Include the representative’s name, title, contact information, and the basis for their authority (attorney, corporate officer, general partner, agent). Agents appointed under Tax Code Section 1.111 must attach Form 50-162.

Section 3: Property Description

Enter the appraisal district’s county, your account number, the total acres, and the legal description from your deed, including any abstract, field, or plat numbers. Answer the yes/no questions about whether the property received 1-d-1 appraisal last year, whether ownership changed since January 1 of the prior year, whether you are a surviving spouse of a deceased owner, whether a new owner is running the land the same way with the same operators, and whether the land sits inside city limits. If the property was already approved and nothing has changed, you can indicate that previously reported information still applies and only supply what is new.¹

Section 4: Property Use

This is the section that gets applications denied when it is done sloppily. Give a year-by-year history of the land’s agricultural use, starting with the current year and going back until you show five out of seven qualifying years.¹ For each year, list the use category and the acres in that use.

Then break out your current operation:

For livestock, exotic animals, and wildlife: type of animal, acres used, and average number of head over the year.
For crops: each crop grown (including ornamentals, flowers, and grapevines) and the acres in each.
For government programs: the program name and enrolled acres.
For non-agricultural portions: what they are used for and the acres involved.

Be specific. “Cattle ranching” with no acreage or head count invites follow-up requests that delay approval and give the appraiser reason to question your intensity.

Section 5: Wildlife Management Use

Only fill this in if wildlife management is your claimed use. List at least three of the seven recognized practices, identify the agricultural category the land held before conversion, and attach your Texas Parks and Wildlife Department wildlife management plan. If the land is part of a wildlife management property association, attach the members’ written agreement. For land protecting federally listed endangered species, attach evidence of the federal permit and any conservation easement or habitat conservation plan.¹

Section 6: Conversion to Timber

Only for owners converting land from agricultural use to timber production while continuing 1-d-1 appraisal. Most applicants skip it.

Section 7: Certification and Signature

Sign, print your name, and date. Your signature certifies the information is true and complete.

Where and When to File

File the completed form with the chief appraiser of the county appraisal district where the property is located. If your property crosses county lines, file a copy in each county.¹ The deadline is May 1 of the tax year you want the appraisal to apply. The chief appraiser can grant an extension of up to 60 days for good cause, but you have to ask; it is not automatic.²

1-d-1 is a one-time filing. Once you are approved, the appraisal carries forward without a new application each year. You only need to file again if ownership changes or the land no longer qualifies. The chief appraiser can also require a new application if there is good cause to think the land no longer qualifies, and in that case you will get a written notice with a new form attached.²

If You Miss May 1

You can still file after May 1 as long as the appraisal review board has not yet approved the appraisal records for the year, which usually happens in July. An approved late filing costs a penalty of 10 percent of the difference between the taxes at the agricultural value and the taxes that would apply at market value.⁵

Two situations waive the 10 percent penalty. First, if the previous owner died during the preceding tax year on land already receiving 1-d-1 appraisal, a surviving spouse, surviving child, executor, or fiduciary can file late without penalty as long as it is before the tax delinquency date. Second, when qualifying land transfers to a new owner who runs it the same way with the same operators, the new owner can file late without penalty by the later of the tax delinquency date or the first anniversary of the transfer.¹

If you never file, or file after the ARB approves the records, the land is ineligible for open-space appraisal that year. There is no retroactive fix.²

What Happens After You File

The chief appraiser reviews your application and supporting data against the five-of-seven-year standard and the local intensity guidelines. Expect a possible site visit and possibly a request for more documentation, including feed and seed receipts, veterinary bills, and sale records for livestock or crops. Anything showing the operation is a real going concern helps.

Once approved, the land is valued by income capitalization based on the average net income the land can produce, and that value cannot exceed the property’s market value.⁶ For most agricultural land, the productivity value is well below market, and the tax bill drops accordingly.

What Can Undo the Appraisal Later

If you stop using the land for agriculture — converting it to residential or commercial use, or just letting it sit idle — you owe rollback taxes. The rollback covers each of the three years before the change of use in which the land received the open-space appraisal, and it equals the difference between the taxes paid at the agricultural value and the taxes that would have applied at full market value for those years. On land that has been appraised far below market for years, the bill is meaningful. Rollback taxes are due before the next February 1 that falls at least 20 days after the bill is delivered; miss that date and standard delinquency penalties and interest apply.⁷

You also have to notify the appraisal office in writing before May 1 if the land’s eligibility ends or its use category changes. Skip the notice and you owe a separate 10 percent penalty on the tax difference for each year the land wrongly received the appraisal, and the chief appraiser can add up to five years of escaped taxes back onto the appraisal roll.²

If Your Application Is Denied

You can protest a denial to the appraisal review board using Form 50-132, the Property Owner’s Notice of Protest.⁸ Bring documentation to the hearing: lease agreements, receipts for agricultural expenses, proof of livestock sales, and photos of the operation. If the ARB rules against you, the next step is district court.
