Rollback Taxes: What Happens If You Lose Your Ag Exemption

What is a rollback tax?

A rollback tax (the Tax Code calls it an “additional tax”) is the bill that comes due when land that’s been getting the 1-d-1 open-space valuation changes to a non-agricultural use. The idea is simple: the state let you pay taxes on the land’s low productivity value on the promise that it stayed in agriculture. If the use changes — a subdivision goes in, the cattle leave and never come back — the county collects the difference for recent years.

It’s not a fine, and it’s not triggered by simply selling land. It’s triggered by a change of use, whoever owns the land when it happens.

How rollback taxes are calculated

Under Texas Tax Code §23.55, when the use changes, the additional tax equals the difference between the taxes actually paid on productivity value and the taxes that would have been paid on market value, for each of the applicable years before the change.

The bigger the gap between your land’s market value and its agricultural value, the bigger the rollback. Land on the edge of a growing town — exactly the land most likely to be developed — carries the largest rollback exposure.

The lookback period: three years (it used to be five)

You’ll still hear “five years of rollback taxes plus interest” everywhere — from agents, forums, even county staff. That’s the old law. Two changes matter:

• House Bill 1743 (effective September 1, 2019) cut the lookback from five years to three years and reduced the annual interest from 7% to 5%.
• House Bill 3833 (effective June 15, 2021) then removed the automatic annual interest on 1-d-1 rollbacks entirely.

So today: a rollback covers the three years preceding the change of use, with no built-in interest. (If you don’t pay the bill by the delinquency date, normal penalties and interest apply, like any property tax bill.)

Common triggers: development, lease lapses, failed reviews

The most common ways landowners trip the rollback — or lose the valuation that protects them from it:

• Development. Building non-agricultural structures, paving, subdividing into lots. The classic case.
• Ag use simply stopping. The neighbor who leased your pasture retires, the cows leave, and the land just sits. No use = no qualification, and an extended lapse can be treated as a change of use.
• Buying land and doing nothing. The valuation’s history follows the land, but a new owner must keep the agricultural use going (and file their own application). Letting it lapse after purchase is a frequent and expensive surprise.
• Failed intensity reviews. Falling below your county’s degree-of-intensity standards doesn’t automatically trigger a rollback, but it can cost you the valuation — and if the district concludes the agricultural use has actually ended, a rollback determination can follow.

How a “change of use” gets flagged

Appraisal districts don’t rely on you volunteering the information. Changes of use typically surface through:

• Aerial and satellite imagery — most CADs review it regularly and can see cleared pads, new roads, and empty pastures
• Building permits and septic applications
• Subdivision plats and deed records after a sale
• Periodic qualification reviews, where the district asks you to prove ongoing use

When the chief appraiser determines a change of use occurred, they send a formal notice — and the clock starts on your right to respond.

What to do if you receive a rollback notice

1. Don’t ignore it. You have the right to protest the change-of-use determination to the Appraisal Review Board, but the window is short — check the notice for the deadline and act immediately.
2. Call the appraisal district first. Some determinations rest on a misunderstanding (imagery taken between grazing rotations, a lease they didn’t know about). A conversation plus documentation resolves more cases than people expect.
3. Gather your evidence. Dated photos, grazing leases, feed and vet receipts, livestock records — anything showing agricultural use continued through the period in question.
4. Get help for big exposures. If the rollback is substantial, a property tax consultant or attorney who works your county is worth the fee. (We’re neither — this is general information, not advice.)

How to protect yourself: documentation that actually holds up

Rollback fights are won and lost on records. The landowners who survive reviews are the ones who can show, with dates, that agricultural use never stopped:

• Photos of livestock, hives, or crops taken through the year, not one springtime snapshot
• Written leases whenever someone else grazes or cuts your land — a handshake deal proves nothing later
• Receipts for feed, seed, fencing, and vet work, kept by year
• A simple log of animal counts matched against your county’s intensity standard

That’s the record-keeping burden our upcoming app is built to automate — timestamped, GPS-tagged evidence, organized the way appraisal districts expect it. Join the waitlist if that’s a problem you’d rather not manage in a shoebox.

Real numbers: what rollback taxes can cost on a 50-acre tract

Illustration only — round numbers, and every county’s rates and values differ:

	Market value	Ag (productivity) value
Value of 50 acres	$500,000 ($10,000/acre)	$7,500 ($150/acre)
Taxes at ~1.8% total rate	~$9,000/year	~$135/year

Annual difference: roughly $8,865. If a change of use triggers a rollback covering three years: ~$26,600 due — on top of the land being taxed at market value from then on.

Under the pre-2019 law, the same scenario would have been five years plus 7% interest — roughly double. The law got friendlier; the bill is still large enough to sink a land deal or blow up a family budget.

Summary checklist

• Rollback = the tax difference between market value and ag value for the three years before a change of use (no automatic interest since 2021).
• Selling doesn’t trigger it — stopping agricultural use does. Buyers: file your own application and keep the use going without a gap.
• Know your county’s degree-of-intensity standards and stay above them.
• Keep dated records — photos, leases, receipts, counts — every year, so a review never becomes a rollback.
• If you get a notice: don’t ignore it, call the CAD, protest before the deadline, bring evidence.
