Kentucky Drops the 200-Transaction Nexus Test on August 1. Deciding Whether to Deregister Is the Harder Half.

On Saturday, August 1, 2026, two provisions of Kentucky House Bill 757 switch on. The first removes the 200-transaction prong from Kentucky's economic nexus test. The second extends the state's 6 percent sales and use tax to data brokering services. Both were enacted back in April; what happens this week is the effective date, and for agent operators the first provision is the one that changes the arithmetic.

It also creates a decision that nothing in the statute makes for you. Kentucky's own guidance is explicit that a sales and use tax account "remains active until canceled by the retailer." Losing nexus on August 1 does not deregister anybody.

What Actually Changes on the Date

HB 757 was delivered to the Secretary of State as 2026 Acts Chapter 161 on April 14, 2026. Two of its sales tax provisions matter here.

KRS 139.340 — the nexus test. Kentucky's post-Wayfair standard has been the familiar pair: more than \$100,000 in gross receipts from sales sourced to Kentucky, or 200 or more separate transactions sourced to Kentucky. As of August 1 the transaction count is gone, for remote retailers and marketplace providers alike. Only the \$100,000 receipts test survives. Kentucky measures it against the previous or current calendar year.

KRS 139.200 — data brokering services. The Act enumerates "data brokering services" as a taxable service, defined as the act of collecting, aggregating, and analyzing personal data for sale to a third party while possession of the personal data is maintained by the provider or by the third party, wherever located, and regardless of whether the charge is on a per use, per user, per license, subscription, or other basis. Services provided by state agencies, cities, counties, and special districts are excepted. The Senate Committee Substitute narrowed the definition before passage by dropping language that would have reached downstream use of the data by a third party.

Kentucky joins a growing group of states that have concluded a raw transaction count sweeps in sellers with no meaningful economic presence. Illinois made the same change effective January 1, 2026.

Why the Count Was the Prong That Bit

For a conventional retailer, 200 transactions and \$100,000 in receipts tend to arrive in roughly the same neighborhood. For agent commerce they do not arrive anywhere near each other.

Run the arithmetic on metered API pricing. An agent product billed at four cents a call crosses 200 separate transactions at eight dollars of Kentucky revenue. Under the pre-August rule, eight dollars of receipts produced the same registration obligation as \$100,000 — a permit, a filing frequency, a return every period, and the exposure that comes with getting any of it wrong. The count was the binding constraint for high-volume, low-value activity, and it bound at a level of revenue that could not pay for the compliance it triggered.

One caveat worth stating plainly: whether transactions initiated by an autonomous agent count toward a state's economic nexus threshold at all is unresolved. No state has issued guidance addressing agent-initiated commerce specifically, and the question is genuinely open rather than merely undecided by Kentucky. What August 1 does is remove the prong on which that open question was most expensive to guess wrong in one state. It does not answer it, and the uncertainty still lives in every state that kept its count.

The Deregistration Decision

Here is the part the coverage skips. The repeal is prospective and self-executing as to the test. It is entirely inert as to your account.

Kentucky's remote retailer guidance states that account numbers remain active until canceled by the retailer. An active account carries a filing obligation for every assigned period whether or not you made a sale — a zero return, filed on time, with a late-filing penalty and eventual permit revocation waiting if you skip it. Returns are due by the twentieth of the month following the reporting period under KRS 139.540. So a seller who registered in Kentucky solely because of the transaction count, and who is nowhere near \$100,000, is on August 1 filing zero returns forever unless it affirmatively closes the account.

Work the decision in this order.

1. Establish why you are registered. Transaction count alone, receipts, physical presence, inventory, employees or contractors, marketplace facilitator status, or a voluntary registration you took on to issue or accept exemption certificates. Only the first is cured by August 1. Cancelling an account does not unwind physical presence, and it does not help a facilitator that meets the definition on other grounds.

2. Test both measurement years, not one. The threshold looks to the previous or current calendar year. On August 1 that means 2025 and 2026-to-date. Clearing 2025 is not enough — 2026 has five months left to run, and a seller who cancels in August and crosses \$100,000 in November has nexus again, with a registration deadline that runs from the crossing and not from the year end. Kentucky's published guidance for remote retailers sets that deadline at the first day of the calendar month falling at most sixty days after the threshold is reached; the Department's marketplace provider FAQ states thirty days. Read the current guidance for your own posture rather than working from either number secondhand.

3. Price the two errors against each other. Staying registered while below threshold costs you a zero return per period and the discipline to keep filing it. Cancelling and later crossing costs you an unregistered collection period — uncollected tax you now owe out of margin, plus interest and penalty, and the gap is typically discovered months later during a year-end review. Those are not symmetric. If your trailing Kentucky receipts are anywhere within reach of \$100,000 — and for a growing agent business, "within reach" should be read generously — stay registered. I would rather explain a stack of zero returns than an uncollected-tax assessment. If you are structurally far below and expect to stay there, cancel, and write down the analysis and the numbers you relied on before you do.

4. Do not stop collecting mid-period. Tax you have already collected is held in trust and is owed to the Commonwealth regardless of what your nexus looks like after August 1. Close the account through the Department's process, file the final return, remit what you hold. An operator who quietly stops collecting on August 1 while leaving an active account open has produced the worst of both outcomes.

5. Check whether the other provision pulls you the other way. This is one bill with two effective dates that happen to be the same day. If your product collects, aggregates, and analyzes personal data and sells the result to a third party, you may be shedding an economic nexus trigger and acquiring a taxable service line in the same twenty-four hours. Note the definition's three conjunctive verbs and the "for sale to a third party" limitation — a product that does two of the three, or that analyzes data for the customer who supplied it, sits outside the plain language. Department guidance on the scope of the new category remains thin, and that boundary is where I expect the first disputes.

What to Watch

The Kentucky Department of Revenue has not published substantial administrative guidance on the data brokering category, and the definition is broad enough that vendors of enrichment, identity resolution, and audience data will need it. Watch for a Sales Tax Facts item or a technical bulletin addressing what "analyzing" requires and whether an AI-driven enrichment product falls inside.

On the nexus side, the direction of travel is now unmistakable. States are dropping transaction counts, and each removal quietly reduces the number of jurisdictions where the unsettled question of agent-initiated transactions has a five-figure price tag attached. Connecticut, Georgia, Hawaii, New Jersey and Rhode Island still count.

What Agent Operators Should Do This Week

• Pull your Kentucky receipts for 2025 and 2026-to-date. The number, not the transaction count, is now the only economic nexus fact that matters.

• Determine why your Kentucky account exists. If the answer is not "the transaction count," August 1 changes nothing for you.

• Decide deregistration deliberately, and default to staying registered when the receipts figure is close. Zero returns are cheap.

• If you sell data brokering services, treat August 1 as a start date, not a repeal date, and get your billing configured before the first invoice goes out.

Knowing which states still count transactions, and which of your agent's calls are taxable in each, is the part of this that does not scale by hand. AgentTax tracks economic nexus thresholds per state and flags when your activity approaches one. See how it works at agenttax.io. For the registration mechanics themselves, the Streamlined Sales Tax Project's registration guidance is the right starting point.
