What Triggers a Rollback
A rollback tax is triggered when land that has been receiving agricultural special valuation — and the resulting dramatically lower tax bill — is converted to a use that no longer qualifies for that valuation. Texas Property Tax Code Section 23.55 governs the rollback mechanism.
Common rollback triggers include:
- Subdivision into residential lots — the most common trigger; selling off tracts for development
- Sale to a developer — even without immediate subdivision, if the buyer intends non-agricultural use
- Conversion to commercial use — building a commercial facility on ag-valued land
- Discontinuation of qualifying agricultural activity — allowing the land to sit idle without any qualifying use
- Failure to maintain the qualifying use — e.g., a cattle lease expires and is not replaced
How the Rollback Is Calculated
When a rollback is triggered, the property owner must pay:
- The difference between the taxes paid under agricultural special valuation and what would have been owed at full market value appraisal
- For each of the preceding five years
- Plus 7% per year interest on each year's difference
On a 100-acre Hill Country property with market value of $1,000,000 and agricultural valuation of $65,000, the annual tax difference might be $14,000–$17,000 per year. A five-year rollback plus interest could total $80,000–$100,000+ — a significant number that can dramatically affect the economics of purchasing land with the intention of developing or selling it.
Who Pays — and When
The rollback obligation attaches to the land at the time of the triggering event. If you purchase a property and then trigger a rollback by converting the use, you pay the rollback — even though the low-tax period included years before you owned the land. This is why rollback potential is an important due diligence item for any buyer who plans to change the land's use after purchase.
The rollback tax is typically assessed and billed by the appraisal district within the tax year following the triggering event. If you are purchasing a property specifically for development or subdivision, you need to factor the potential rollback cost into your acquisition economics before you close.
Rollback in Purchase Negotiations
When a seller knows their buyer intends a non-agricultural use, the rollback liability is often addressed in the purchase contract — either through a price adjustment, seller indemnification, or an explicit allocation of rollback responsibility. A buyer who does not address rollback in the contract and then triggers it has no contractual recourse against the seller for the liability incurred.
