Every agricultural valuation in Texas runs through one document: Form 50-129, the Application for 1-d-1 (Open-Space) Agricultural Use Appraisal. We file these alongside landowners across 40+ North Texas counties every year. The form itself takes twenty minutes. The applications that fail are the ones filed without proof behind them. Here is the full walkthrough.

What the form actually asks
Form 50-129 wants four things: who owns the land, the legal description and account number from your appraisal notice, what agricultural use the land is under (beekeeping counts under Tax Code Section 23.51), and the history of that use. The history section is where applications live or die. The district is looking for agricultural use in 5 of the past 7 years, and they want you to name the use for each year.
The deadline that matters
File by April 30 with your county appraisal district — not the tax office, not the county clerk. Miss it and you can still file late until the appraisal roll is certified (usually mid-July), but you pay a 10% penalty on the tax savings for that year. After certification, you wait until next year. If you are switching an existing Ag valuation to beekeeping, the same deadline applies to the new application in your name.
What to attach
The form does not require attachments. Winning applications include them anyway. For beekeeping: your hive management contract, receipts for colonies and equipment, photos of hives on the property with something identifiable in frame, TAIS beekeeper registration if you have it, and a simple map showing hive locations on the tract. If the appraisal district can approve your application without calling you, you did it right.
The three mistakes that get applications denied
First: claiming acreage the statute does not allow. Beekeeping qualifies 5 to 20 acres of open-space land, and the district will carve out roughly an acre under your house. Second: vague history. Writing 'grazing' across five years with no lease, no receipts, and no county record invites a denial. Third: filing in the wrong name after a purchase. The valuation follows the land, but the application must be in the current owner's name — new owners must re-file, even when the land already carries the valuation.
After you file
Districts may approve, deny, or request more information. A request for more information has a deadline attached — miss it and the application is treated as waived. If you are denied, you have protest rights with the Appraisal Review Board, and the deadlines move fast. We cover that fight in a separate guide.
If you would rather hand the whole thing off — hives placed to your county's standard, records kept, application supported with documentation the district cannot argue with — that is exactly what we do. Request a quote from your county's page and we will take it from there.
Filing FAQs
Do I have to file Form 50-129 every year?
No. It's a one-time application filed when you first claim the valuation. The qualifying use has to continue every year, and the appraisal district can ask for a new application or verify your use — but annual re-filing isn't the normal requirement.
What's the deadline to file Form 50-129?
April 30 for the tax year you're claiming. Late applications are accepted until the appraisal roll is certified (typically mid-summer), but they carry a 10% penalty on the tax savings — filing on time is free, filing late isn't.
Where do I send the form?
To your county appraisal district (CAD) — not the tax assessor-collector's office. Every one of our county pages lists the CAD mailing address, phone, and website for that county.
I bought land that already has an ag valuation. Do I still need to file?
Yes. The land's use history carries over to you, but the application doesn't — new owners file their own Form 50-129 to keep the valuation in their name.
