Eyeing land near Bellville or New Ulm and wondering how an ag exemption affects your taxes and plans? You are not alone. The rules feel technical, and timing matters when you are buying acreage. In this guide, you will learn how Texas agricultural valuation works, what you actually inherit at closing, the deadlines to hit in Austin County, and how to keep or establish your special appraisal. Let’s dive in.
Ag exemptions in Texas, plain English
An “ag exemption” in Texas is not a tax-free pass. It is a special appraisal that values qualifying land based on agricultural productivity instead of market value. That often lowers your taxable value, but you still pay property taxes on the land and on non-ag improvements like homes and barns. You can read the state’s overview of agricultural and wildlife special appraisal on the Texas Comptroller’s site for a plain-language summary and forms.
When land qualifies, the appraisal district uses an income-capitalization method to set a per-acre productivity value. This is why two similar tracts can show very different taxable values if one has an approved agricultural appraisal and the other does not. The rules live in state law, and your local appraisal district applies them.
See the Comptroller’s guidance on agricultural and wildlife special appraisal.
Two paths: 1-d vs 1-d-1
1-d agricultural-use appraisal
This path ties eligibility to the owner as an active farmer or rancher. Statute requires agricultural use for the three years before application and other owner-based tests. It is less common for recreational or part-time owners because it focuses on the owner’s occupation and direct engagement in production.
1-d-1 open-space appraisal
This path focuses on the land’s use and history. Land must be devoted principally to agricultural use for a set period, commonly five of the past seven years. 1-d-1 is the route most buyers use because it does not require farming to be your primary occupation.
Degree of intensity and proof
Whichever path you take, the land must be used to a degree of intensity that is generally accepted in the area. The chief appraiser looks for consistent, real agricultural activity. Keep receipts, leases, livestock counts, photos of fences and watering points, and other dated records to show normal local intensity. Appraisal districts often share examples of helpful documentation in their FAQs and knowledge bases.
Review a sample list of evidence districts may request.
For the statutory framework that defines these paths, review Chapter 23 of the Texas Tax Code.
Read the statute sections that cover 1-d and 1-d-1.
Austin County process: where to file and when
In Bellville and New Ulm, you work with the Austin County Appraisal District (ACAD). ACAD posts contacts, forms links, deadlines, and processing updates. It is also the place to confirm a property’s current appraisal status and history.
Visit the Austin County Appraisal District site.
Applications use state forms. Most buyers file Form 50-129 for open-space (1-d-1), while 50-165 applies to the owner-based 1-d route. File with the chief appraiser at ACAD. The statutory deadline is before May 1 of the tax year. ACAD may process applications in several weeks and can request more information or a field visit, so start early.
Statute allows a single extension for good cause and outlines late filing penalties if your application is approved after the deadline but before the appraisal roll is certified. The county follows those rules in practice. When in doubt, call ACAD well ahead of May 1.
See the statute on deadlines, extensions, and late-application penalties.
Buying land with an existing ag valuation
What carries over in the purchase year
Texas appraises property as of January 1. If the seller owned and qualified the land on January 1, that year’s roll will reflect the agricultural classification even if you close later that year. That helps in the current tax year, but you still need to plan for your first full year of ownership.
Review the Comptroller’s explanation of how special appraisal works across tax years.
Why you still need to act
A change in ownership usually requires the new owner to file or notify the appraisal district to keep the special appraisal for future years. Do not assume it transfers automatically. The statutes spell out application rules and the ownership-change clause.
Check the application and ownership-change rules in Chapter 23.
A quick due diligence checklist
Before you close, gather the paper trail and confirm status. Ask for:
- Copies of the seller’s filed ag application (Form 50-129 or 50-165)
- Prior tax statements showing agricultural classification
- Leases, production receipts, livestock records, photos, or a wildlife-management plan
- A property search printout from ACAD that shows the current appraisal class and history
Deadlines, late filings, and rollback taxes
Key dates to remember
Appraisal is set as of January 1. File your ag or open-space application before May 1. The chief appraiser can grant one 60-day extension for good cause. If your late application is approved before the roll is certified, a penalty equal to 10% of the tax savings generally applies for that year.
Read the statute that covers deadlines and penalties.
Heirs and the late-filing exception
There is a narrow exception for late applications when ownership changes because of a death. If certain filing conditions and deadlines are met, statute allows a penalty-free late filing by qualifying survivors or fiduciaries. This is useful to know if you inherit land and need to protect the special appraisal.
See the relevant sections in Chapter 23.
Rollback risk if you change use
If you convert qualifying land to non-agricultural use, the state can assess rollback taxes that recapture the difference between market-value taxes and the taxes you paid under special appraisal for a statutory lookback period. The Comptroller and local districts describe the current lookback period for many agricultural and open-space changes as generally three years. Because recent sessions have revised lookback and interest rules, confirm the current law before you act.
In practice, buyers and sellers often negotiate who pays for any future rollback if a development or subdivision is planned. Get clear contract language so both sides understand the risk.
Read a Texas Bar article on allocating rollback risk in contracts.
Establishing or keeping your ag valuation
Show your use with organized records
Appraisal districts look for dated, organized evidence that shows real agricultural use at a locally accepted intensity. Useful items include:
- Prior ag applications and approvals
- Signed leases or affidavits for verbal leases
- Receipts for seed, hay, or feed
- Livestock counts or brand inspection records
- Photos of fences, water sources, and grazing areas
- For wildlife-management, a written plan and reports of the required practices
See examples of documentation districts commonly request.
Minimum acreage depends on county practice
There is no single statewide acreage minimum for every ag use. Beekeeping has a statutory range that references 5 to 20 acres in certain cases. For wildlife-management or other uses, the chief appraiser can apply county-appropriate minimums. Check Austin County’s guidelines with ACAD before you buy or reconfigure acreage.
Review TPWD’s legal summary and planning guidance.
Considering wildlife-management use
Wildlife-management can be a qualifying use if you implement an approved plan and complete at least three of the listed practices, such as habitat control, supplemental water, and predator control. Follow Texas Parks and Wildlife regional guidelines and coordinate with local experts so your plan meets Austin County’s degree-of-intensity standards.
