The ag exemption in Collin County is technically an agricultural appraisal, not an exemption, and it lets qualifying farm or ranch land be taxed on what it produces rather than what it would sell for. In a county where suburban demand has pushed market values sky-high while farming income stays modest, that shift often cuts a property’s taxable value by 90 percent or more. To get it, you have to use the land for agriculture at the intensity the Collin Central Appraisal District expects, show a five-of-seven-year history of that use, and file the application before May 1.
What Land Qualifies
Two tests have to be met. The land must be “currently devoted principally to agricultural use to the degree of intensity generally accepted in the area,” and it must have been used for agriculture during at least five of the preceding seven years.1State of Texas. Texas Tax Code 23.51 – Definitions That history runs with the land, not the owner, so a buyer can rely on the prior owner’s agricultural use to meet the five-year requirement.
“Principally devoted” means agriculture is the land’s primary purpose. Hobby farms, personal horse pastures where the animals are pets, and land sitting idle while the owner waits for a developer’s offer do not qualify. Collin CAD measures intensity by comparing your actual output against what a typically prudent farmer or rancher in the county would produce on similar land.2Collin Central Appraisal District. Agricultural Land Qualification Guidelines Production that falls well below local norms can get the special appraisal denied or revoked.
Minimum Acreage and Stocking Rates for Grazing
For pastureland, Collin County requires a minimum of two animal units kept on the property for at least 180 days a year. One animal unit equals roughly 1,000 pounds of livestock, so a mature cow typically counts as one unit. How much land you need depends on pasture type:2Collin Central Appraisal District. Agricultural Land Qualification Guidelines
- Improved pasture such as Bermuda: 3 to 5 acres per animal unit, roughly 6 to 10 acres minimum for two units.
- Native pasture: 4 to 6 acres per animal unit, roughly 8 to 12 acres minimum for two units.
Small tracts that were developed or marketed as residential and can’t support a viable operation generally will not qualify even if the owner runs a few animals on them. The district looks at whether the operation makes economic sense as a whole, not just whether livestock are present.
Beekeeping and Wildlife Management
Texas treats beekeeping as a qualifying agricultural use, with a minimum of 5 acres and a maximum of 20 acres. You have to maintain active hives and be able to show evidence of honey production or pollination activity. Beekeeping has become a common route for smaller Collin County tracts that can’t support cattle, but the district still expects a real, functioning apiary rather than a few neglected hive boxes.
Wildlife management is another path, with an important catch. The property must already have been receiving agricultural appraisal when the wildlife management use began; raw, non-agricultural land can’t jump straight to wildlife management. You have to implement at least three of seven recognized practices (habitat control, erosion control, predator control, supplemental water, supplemental food, shelters, or census counts) and file a wildlife management plan identifying target species. Each activity has to meet the intensity standards the Comptroller and Texas Parks and Wildlife have set for your ecoregion.3Texas Parks and Wildlife Department. Agricultural Tax Appraisal Based on Wildlife Management
Livestock production (cattle, horses, sheep, goats, swine, poultry) and crop production (hay, row crops, other harvested products) are the other main qualifying activities. Every operation has to show genuine productive output: calves sold at auction, hay baled and sold, grain delivered to a buyer.
How to Apply
New applicants file Texas Comptroller Form 50-129, Application for 1-d-1 (Open-Space) Agricultural Use Appraisal, with Collin CAD.4Texas Comptroller of Public Accounts. Application for 1-d-1 (Open-Space) Agricultural Use Appraisal The form is available from the Comptroller’s website, from Collin CAD, or at the district’s McKinney office.
Expect to provide your property account number, a description of the acreage used for agriculture, and a seven-year land-use history that demonstrates the five-of-seven requirement. Supporting documents make the application stronger: grazing leases, livestock sale receipts, crop production records, feed and supply invoices, and clear maps showing which portions of the property are dedicated to each activity. Describe the current year’s operation in enough detail that an appraiser can compare it to the district’s intensity standards.
The May 1 Deadline
File before May 1 of the tax year you want the agricultural appraisal. The chief appraiser may grant up to a 60-day extension for good cause.5State of Texas. Texas Tax Code 23.54 – Application Applications filed after the deadline but before the appraisal roll is certified are treated as late. If a late application is approved, you owe a penalty equal to 10 percent of the difference between taxes at agricultural value and taxes at full market value.6Texas Public Law. Texas Tax Code 23.541 – Late Application for Appraisal On a property where the market-value bill would be several thousand dollars higher, that adds up quickly.
When You Have to Reapply
Once Collin CAD approves the appraisal, it carries forward automatically. You don’t file every year unless ownership changes or eligibility ends.5State of Texas. Texas Tax Code 23.54 – Application A transfer to the surviving spouse of the former owner doesn’t count as a change of ownership.
If ownership does change, the new owner has to file. When the new owner continues the same use with the same people managing the operation, Form 50-129 allows an abbreviated filing covering only what has changed.4Texas Comptroller of Public Accounts. Application for 1-d-1 (Open-Space) Agricultural Use Appraisal If the operation itself turns over or the new owner shifts to a different agricultural use, a complete application is required. The chief appraiser can also demand a new application anytime there’s good cause to believe the land no longer qualifies.
The Rollback Tax if Use Ends
This is the piece that catches owners off guard. If the land loses its agricultural appraisal because you change how you use it, the county collects a rollback tax covering the previous three years. The rollback equals the difference between what you paid under the agricultural appraisal and what you would have paid at full market value for each of those years.7State of Texas. Texas Tax Code 23.55 – Change of Use of Land In Collin County, that can run to tens of thousands of dollars.
For 1-d-1 land, which covers the vast majority of agricultural properties in Collin County, no interest is added to the rollback.8Texas Comptroller of Public Accounts. Agricultural, Timberland and Wildlife Management Use Special Appraisal The rollback also doesn’t apply when the change of use results from condemnation, a sale for right-of-way, or a transfer to a government entity for public purposes.7State of Texas. Texas Tax Code 23.55 – Change of Use of Land If only part of a parcel changes use, the rollback applies only to that portion. A tax lien attaches to the land on the date the change occurs, so the obligation follows the property even if it’s sold before the bill arrives.
Protesting a Denial
If Collin CAD denies the application, you can protest to the Appraisal Review Board. The deadline is May 15 or 30 days from the date the district mails notice, whichever is later.9Texas Comptroller of Public Accounts. Appraisal Protests and Appeals File the written protest promptly even if you plan to try informal negotiation first, because missing the deadline forfeits your right to a hearing.
The Appraisal Review Board is a panel of local citizens who hear disputes between property owners and the appraisal district.10Texas Comptroller of Public Accounts. Appraisal Review Boards Bring everything to the hearing: photos of the land in active use, livestock purchase and sale records, feed receipts, lease agreements, anything showing your operation meets the district’s intensity standards. Most denials turn on whether the use matches the intensity the district expects, and concrete production records are the strongest rebuttal.
