What is an ag exemption, really?
In most states an agricultural exemption is not a true exemption. It is a special-use valuation: the county assesses the land on its value for farming, ranching, timber or wildlife management rather than its full market value. The taxable value, and the tax bill, are lower. Names and rules vary: Texas calls it open-space (1-d-1) appraisal, and other states use current-use or greenbelt programs. The Texas Comptroller notes that the productivity value is usually lower than market value; see its agricultural and timber appraisal page.
Why does the tax bill understate what the land is worth?
If you price your land from the taxable value on your tax statement, you may badly undervalue it, because that figure reflects agricultural use, not market value. Market value depends on location, acreage, access and development pressure. The county records a market value as well, so look for that line in your appraisal-district record. A buyer who prices only from the taxable figure, in either direction, is not giving you the real picture. See how land is valued.
What is a rollback tax?
When land that has been valued for agriculture changes use, many states recover some of the tax that was saved. This is the rollback tax, sometimes called a recapture or change-of-use tax. Points that matter at sale:
- The rollback is usually triggered by a change in use, not simply by selling. Land that keeps its agricultural use can often transfer with the valuation intact.
- Who pays any rollback, buyer or seller, is a negotiated term. It should be spelled out in writing before closing.
- The number of prior years recovered and the interest charged vary by state, so confirm your state’s rule.
Texas: what does the statute say about rollback?
Texas Tax Code §23.55, titled “Change of Use of Land,” imposes an additional tax for each of the three years preceding the year in which the change of use occurs. The additional tax equals the difference between the taxes imposed on the land in those years and the taxes that would have applied at market value. A tax lien attaches to the land on the date the change of use occurs. If the additional tax is not paid when due, it can become delinquent and incur penalties and interest like other property taxes. See the text of §23.55, and ask your appraisal district how it applies to your parcel.
Where does this come up most?
Ag valuations are common on rural and metro-fringe land, and they matter most where farmland sits next to growth. In our Texas markets, see the county pages for Collin County and Travis County, which link to local appraisal-district tools.
Outside Texas, verify rather than transplant the rule
Rollback rules, look-back periods, interest and who is liable differ sharply by state. Confirm your state’s rule with the assessor and a professional licensed there. A rollback period from one state should never be assumed in another.
What should you ask a buyer?
- Does the buyer intend to keep the agricultural use, or change it?
- Who will pay any rollback, and where is that in the contract?
- Was the offer built from market value or from the taxable value?
Settle these in writing, and confirm rollback rules with a professional. We are not a law firm, a CPA firm, or a brokerage, and nothing here is legal or tax advice.
Common mistakes when selling agriculturally valued land
- Quoting the taxable value as the price. The taxable figure reflects farm or ranch use. Start from the market value line and from comparable sales, not the bill.
- Ending the ag use before closing without thinking it through. Clearing, building, or stopping the qualifying use can change the tax picture. Talk to the appraisal district first.
- Leaving rollback out of the contract. If the contract is silent, the dispute shows up at the closing table. Name who pays, or state clearly that no change of use is planned.
- Assuming the buyer knows the program. Some buyers expect the valuation to continue automatically. Others plan to change the use. Ask which.
What to gather before you call the appraisal district
- Your parcel ID and the owner name exactly as it appears on the record.
- The latest appraisal notice showing both the market value and the productivity value.
- Any ag application, lease, grazing agreement or management plan you filed.
- A note of what the buyer says they intend to do with the land.
Then ask the district plain questions. Does this change of use, as the buyer describes it, end the special valuation? Is any additional tax likely to be assessed, and for what period? Who is billed, and when? Ask for the answers in writing where you can, and keep them with your closing file.
How different situations play out
| Situation | What to ask |
|---|---|
| Buyer keeps farming or ranching | Does the valuation carry over, and does the buyer need to file anything? |
| Buyer plans to build or subdivide | Is a change of use likely, and who pays any additional tax? |
| Buyer is unsure | Can the contract say who pays if a change of use happens later? |
| You lease the land to a farmer | What do the lease terms say about ending it, and does the tenant need notice? |
If a lease is in place, read it before you promise a buyer a clear start date. A CPA or attorney can tell you how any tax cost affects your net proceeds, and the title company can show how it appears on the closing statement.
