What Is the Texas Ag Exemption? Quick Answer + Where to Go Next
What is an ag exemption in Texas? Learn how your land qualifies for agricultural tax valuation, which activities count, and how to apply in your county.
The Texas "ag exemption" is not technically an exemption. It is a special property tax appraisal under Article VIII, Section 1-d-1 of the Texas Constitution that values land based on its agricultural productivity instead of its market value. The savings are typically 70 to 90 percent off the market-value tax bill, and on suburban land bordering development the difference can exceed 99 percent.
Three things qualify the land:
- Agricultural use history for 5 of the preceding 7 years (transfers from a prior owner if continuous)
- Acreage that meets the county's standard for the type of operation (no statewide minimum; varies)
- Intensity of use typical for the area - meaning a real operation, not a hobby
That is the whole answer at a high level. The county-specific details are where most applications win or lose.

How It Differs from a Homestead Exemption
The homestead exemption reduces taxable value by a flat dollar amount (currently $140,000 off school district value for most Texas homeowners). It is automatic once filed and does not depend on land use.
The ag valuation is different in every way: it changes the valuation method entirely and depends on continuous agricultural use. Once approved, it carries forward automatically. A new application is not required in later years unless the ownership changes, the land stops qualifying, or the chief appraiser requests one. If the land stops qualifying, you must notify the appraisal office in writing before May 1. A property can carry both - the homestead portion and the agricultural portion are valued separately.
Run Your Own Numbers
The savings estimator takes a property's acreage, market value, and county tax rate and returns the agricultural-valuation tax bill against the market-rate tax bill. For specific county requirements, look up the county directly. For beekeeping, consultants like Hive Riot Honey Company can help with county-specific requirements.

This article reflects Texas law current through the 89th Legislature (2025) and the November 2025 constitutional amendment election. SB 4, approved by voters in November 2025, raised the school district residence homestead exemption from $100,000 to $140,000 beginning with the 2025 tax year, and the figure in this article reflects that change. The rollback description reflects Tax Code Section 23.55, which recaptures the tax difference for the three preceding years; the older five-year rollback with 7 percent interest no longer applies to 1-d-1 open-space land.

Verified August 6, 2026. County appraisal districts set their own degree-of-intensity standards, so acreage requirements and intensity expectations vary by county and use type; confirm the local standard with your appraisal district before filing.
