Conservation Easements vs. Ag Exemptions
These two tax strategies serve different purposes, affect different taxes, and are not mutually exclusive. Most Texas landowners benefit from both. Here is how they compare.
Property Tax Reduction
Ag Exemption
- Reduces your annual Texas property tax bill
- Requires active agricultural use each year
- Apply through your county appraisal district
Federal Income Tax Deduction
Conservation Easement
- Deduct donated land value from federal income taxes
- Permanently protects your land's character
- Requires an attorney, appraiser, and land trust
Yes - most landowners do both.
Ag exemptions reduce your annual property tax. Conservation easements generate a one-time federal income tax deduction. They affect different taxes and are fully combinable. Under Texas law, a conservation easement does not affect your eligibility for agricultural valuation.
Full comparison
| Ag Exemption | Conservation Easement | |
|---|---|---|
| Tax type affected | Texas property tax (annual) | Federal income tax (one-time deduction) |
| Who qualifies | Any landowner with qualifying agricultural use | Landowners with qualifying conservation values and a willing land trust; entity-held land must also clear the IRC 170(h)(7) basis limit |
| Minimum acreage | 5-20 acres (varies by county) | No legal minimum, but 100+ acres typical |
| Duration | Annual - must re-qualify each year | Perpetual for a federally deductible donation (IRC 170(h)(2)(C)); a state TFRLCP easement may instead run 30 years, which forfeits the federal deduction |
| Reversibility | Can lose exemption if use changes (rollback tax applies) | Irreversible - development rights are gone permanently |
| Application process | File with county appraisal district | Negotiate with land trust, hire attorney and appraiser (6-18 months) |
| Cost to obtain | Free to apply | $5,000 - $50,000+ in transaction costs |
| Annual requirements | Active agricultural use and annual reporting | None - land trust monitors the easement |
| Typical annual benefit | 70-90% reduction in property tax | One-time deduction spread over up to 16 years |
| Can be combined | Yes - with wildlife, timber, or conservation easement | Yes - does not affect ag/wildlife/timber valuation eligibility |
Which one is right for you?
Choose the scenario that best matches your goals.
Goal: Lower Property Taxes
You want to reduce your annual tax bill
Your primary concern is the property tax bill you pay every year. You want an immediate, recurring benefit with minimal cost and paperwork.
Goal: Federal Tax Savings + Land Protection
You want to protect your land and offset a high-income year
You have a significant federal tax liability, own land with development pressure, and want to permanently protect its character while generating a large deduction.
Goal: Maximum Tax Benefit
You run a working ranch and want every available benefit
You already have an ag exemption for property tax savings. Adding a conservation easement generates a federal income tax deduction on top of that - different tax, different benefit, fully combinable.

Not tax or legal advice
This page is general information for Texas landowners. It is not tax or legal advice and it does not create a professional relationship. Whether a conservation easement deduction survives depends on your deed language, how the land is owned, and the facts on your own return. Have a CPA or a tax attorney review your situation before you file.
Federal conservation easement rules have moved three times in recent years. SECURE 2.0 Act section 605 (December 2022) added the partnership and S corporation basis limit now at IRC 170(h)(7). Treasury re-identified syndicated conservation easements as listed transactions by final regulation effective October 8, 2024. And a 0.5% of AGI floor on itemized charitable deductions is reported to apply starting in 2026. The current edition of IRS Publication 526 predates that floor, so confirm it and its effect on your carryforward with your own advisor. It is not built into this site's calculator.

Common questions
What is the difference between a conservation easement and an ag exemption in Texas?
An ag exemption reduces your annual Texas property tax by valuing land at its agricultural productive value instead of market value. A conservation easement generates a one-time federal income tax deduction by permanently restricting development rights. They affect different taxes (property vs. federal income) and have different durations. Once a 1-d-1 valuation is granted it carries forward without a new application unless ownership changes, eligibility ends, or the chief appraiser requests one (Tax Code 23.54(e)), though the land must keep meeting the use and intensity standards every year. A federally deductible easement must be perpetual under IRC 170(h)(2)(C). Most Texas landowners can and do use both.
Can I have both an ag exemption and a conservation easement on the same property?
Yes. Under Texas Parks and Wildlife Code Chapter 84, an agricultural conservation easement does not affect your property's eligibility for 1-d-1 open space agricultural appraisal. Your ag, wildlife, or timber valuation continues as normal after the easement is recorded.
Which should I get first - an ag exemption or a conservation easement?
Start with the ag exemption. It provides immediate, recurring annual property tax savings with minimal cost and effort. A conservation easement is a larger, permanent decision with higher transaction costs and should be considered after you have your property tax situation settled.
