Texas ag exemption and rollback taxes, explained for sellers

Few property tax rules matter more to a rural Texas land sale than the ag exemption and its rollback taxes, which can reach back three years, and few are less understood. Owners assume the discount lasts forever. Buyers sometimes assume the seller will pay any bill that comes later. A short conversation before signing can prevent a very large surprise.

This is general information, not tax or legal advice. Confirm details with your county appraisal district, a CPA and a Texas attorney.

What is the Texas ag exemption?

It is not strictly an exemption. Under the Texas Constitution and Tax Code, land that qualifies for open-space agricultural valuation is taxed on its productive value, meaning what it earns in agriculture, rather than its market value. Because market value in growing areas can be many times productive value, the tax savings can be large.

Land can qualify when it has been devoted principally to agricultural use for a set period and the owner meets the appraisal district’s requirements. Qualifying uses include crops, livestock grazing, hay, orchards and timber production. Wildlife management can also qualify, if the owner uses the land for specific practices on a qualifying tract.

What does the appraisal district look for?

Each county appraisal district has its own forms and standards, within the state rules. If you are unsure whether your land qualifies, call the district.

What are rollback taxes?

If land with an open-space valuation changes to a use that does not qualify, the county can bill a rollback tax. In Texas, that tax is generally the difference between the taxes the owner paid under the ag valuation and the taxes that would have been due at market value, for the three years before the change, plus interest. Before 2019 the period was five years, and the statute changed. Check the current rules with the district.

A change of use can include building a house or subdivision, starting a commercial use or stopping the agricultural activity. A simple sale to another farmer who continues the use does not normally trigger a rollback. A sale to a developer who plans to build usually does.

Who pays rollback taxes in a sale?

The law bills the owner at the time of the change in use. In a typical sale the contract decides who bears the cost. Practices vary.

The title company can help estimate the amount and hold funds at closing. Because the bill arrives after the change in use, a clear contract protects both sides.

How does the ag exemption affect land value?

A low tax bill makes land cheaper to hold. That is part of why many owners keep acreage for decades. It also changes what buyers pay. A developer or builder who must pay rollback taxes sees them as a cost and adjusts the price. An agricultural buyer who plans to continue the use does not. When you compare offers, ask each buyer how they treat rollback taxes, and make sure you compare like with like.

What does a rollback tax look like in numbers?

Here is an invented example to show the idea. It is not a quote, and real bills depend on your appraisal district’s figures.

Suppose a 40-acre tract has an ag valuation. Taxes on the productive value run about $800 per year. If the land were taxed on a market value of $400,000 at a combined rate of about 2 percent, the yearly tax would be about $8,000. The difference is roughly $7,200 per year. Over three years that is about $21,600, plus interest. If the buyer changes the use, that is the order of magnitude of the bill.

Several things change the result. Rates differ by county and taxing unit. Market value may move from year to year. Interest adds a few percent. Only part of a tract may change use at a time. The district computes the final amount, and it can be higher or lower than a simple estimate.

For a seller, the lesson is practical. Ask for the estimate before you sign. If a developer wants to buy and plans to subdivide, make sure the contract spells out who pays. For a statute-level view of the rules, the Texas Legislature publishes the Tax Code online, and your appraisal district can explain how it applies in your county.

What should sellers do before they sell?

1. Find out your current valuation. Check your latest appraisal notice. It will show whether the land has an open-space valuation.
2. Ask the district about rollback exposure. Some districts can give an estimate of what a change of use would trigger.
3. Ask each buyer their plans. A buyer who plans a subdivision treats rollback differently from one who will graze cattle.
4. Put it in the contract. State who pays, how it is calculated and when.
5. Plan for the bill. If you are responsible, the title company can set aside funds.

What other tax points matter to a land seller?

Texas has no state income tax. Federal capital gains tax can apply to the profit on a sale. Land held for more than a year is generally taxed at long-term rates, and inherited land often receives a stepped-up basis. See our article on capital gains and stepped-up basis. Some sellers use installment sales or like-kind exchange options when they reinvest in other property. A CPA can explain which apply.

What counts as a change of use?

A change of use is the event that starts the clock. The district decides, and the rules are specific, so treat this list as a general guide and not as a legal opinion.

When a buyer will not tell you the plan, assume the worst until you know more. A buyer who plans to build will usually say so once you ask directly.

How does the contract change who pays, in dollars?

This example is invented. It builds on the 40-acre example above, where the estimated rollback was about $21,600.

Suppose a developer offers $300,000 and the contract says the buyer pays any rollback. You keep $300,000 before closing costs. Suppose the contract instead says the seller pays. The developer’s offer is effectively $278,400 to you ($300,000 minus $21,600).

Now compare two offers with the same facts. Offer A is $290,000 from a developer, and the seller would pay the rollback. Offer B is $280,000 from a rancher who will keep grazing, so no rollback is triggered. Offer A nets $268,400 ($290,000 minus $21,600). Offer B nets $280,000. Offer B is better by $11,600, even though the headline number is $10,000 lower.

If instead the developer pays the rollback in Offer A, then A nets $290,000 and beats B by $10,000. The same tract, the same buyers and two completely different outcomes, all from one clause. This is why you should compare net proceeds and read the contract line that mentions rollback.

What if only part of the land changes use?

Sometimes a buyer wants to build on a small piece and keep farming the rest. Or you sell part of a tract to a neighbor who will convert it, while you keep the rest. In many cases the district may treat the changed acres separately from the rest, but the details matter and vary by case.

As a rough illustration, suppose 10 of the 40 acres in the earlier example changed use. A simple proportion would put the rollback near a quarter of $21,600, or $5,400 ($21,600 divided by 4). The district’s real figure could be higher or lower, because it depends on the actual values for those acres and on how the remaining land qualifies. Ask the district how it would treat a split before you sign.

Selling part of a tract can also affect whether the remainder still meets the size or use standards. Ask the district before you cut the tract.

How does this differ by situation?

Inherited land with an ag valuation. If heirs inherit land that already has the valuation, they may be able to keep it if the use continues and they follow the district’s process. If the heirs sell to a buyer who changes the use, the rollback question comes up. Ask the district what filings are needed after a transfer. See selling inherited land and heirs property.

Land with wildlife management. Wildlife valuation depends on a plan and on specific activities. If the buyer wants to hunt but not follow the plan, the valuation may end. Ask the district.

Raw acreage with no ag valuation. If the land is taxed on market value, no rollback applies. You can confirm this on your appraisal notice.

Residential lots. Lots inside a subdivision are usually not under an ag valuation. If your lot was once part of a larger tract, check the history.

Land with back taxes. Unpaid taxes and a rollback bill can pile up together. Ask a title company to list everything owed. See selling land with back taxes.

Land near growth. The nearer a tract is to new development, the likelier a buyer is to change the use. See I-35 corridor land values.

What happens, and when?

1. Before you sign a contract. Read your appraisal notice, ask the district about exposure and ask each buyer about plans.
2. In the contract. State the payer of any rollback, how the amount is figured and whether any funds are held back at closing.
3. During the option or title period. The title company reviews tax records and tells you what is owed now.
4. At closing. Taxes owed at that point are paid. If the contract assigns a rollback to a party, funds can be held in escrow.
5. After closing. If the buyer changes the use, the district bills the owner at the time of the change, generally after the fact.
6. Later. The buyer files for continued valuation, if the buyer qualifies. The district decides.

The bill can arrive months after closing. That is why a contract that says who pays, and holds money when needed, protects you.

What documents help, and what should you ask?

Gather your last two or three appraisal notices, your ag application or approval letter, records of livestock, hay or timber, any wildlife management plan, leases and tax statements. If you do not have them, the district can provide copies.

Ask the appraisal district:

• Does my land have an open-space valuation, and which type?
• If the use changed on all or part of the land, how would you figure a rollback?
• What does a new owner have to file to keep the valuation?

Ask a Texas attorney:

• Does my contract say clearly who pays a rollback, and when?
• Should money be held in escrow at closing?

Ask a CPA:

• How do rollback payments affect my taxes on the sale?
• What is the best way to treat the sale in my return?

What mistakes should sellers avoid?

• Assuming the buyer will deal with it. If the contract is silent, a dispute is possible.
• Skipping the question about plans. A buyer’s use drives the result.
• Letting the valuation lapse without checking. Missed filings can cost you the valuation.
• Stopping ag use right before a sale. That can look like a change of use. Talk to the district first.
• Relying on a neighbor’s story. Rules and facts differ from parcel to parcel.
• Comparing offers by price alone. Net proceeds, after any rollback, tell the truth.
• Not asking a CPA about the sale. Rollback is only one of the tax issues.
