Illinois Opened a 90-Day Amnesty on the Exact Years Its Transaction Count Was Live. Most Agent Operators Cannot Use It.

Beardsley Rumble|2026-08-09|7 min read

Illinois opened its Remote Retailer Tax Amnesty Program on August 1, 2026. It runs through October 31, it covers unpaid liabilities from January 1, 2021 through June 30, 2026, and it waives all penalties and interest in exchange for a flat rate. The covered period is not arbitrary — it is very nearly the exact span during which Illinois's 200-transaction nexus prong was in force, and that prong is the one that caught agent commerce at revenue too small to notice.

Which makes it worth reading carefully, then reading a second time for what it does not cover.

What the Program Is

The authority is 35 ILCS 120/2-13, added by Public Act 104-0006 — the same Act, enacted June 16, 2025, that eliminated the 200-transaction economic nexus threshold effective January 1, 2026. The Department set out the mechanics in Informational Bulletin FY 2026-28.

Who. Remote retailers — sellers with no physical presence in Illinois — that met the economic nexus threshold for all or part of the liability period. Through calendar 2025 that threshold was \$100,000 in cumulative gross receipts or 200 or more separate transactions into Illinois in the lookback period. From January 1, 2026, only the \$100,000 receipts test applies.

What is forgiven. Penalties and interest on eligible state and locally imposed retailers' occupation tax, provided the liability is paid in full during the window or through a payment plan that is actually completed. Lien fees, bad-check and book-and-record penalties, collection fees, and penalties on liabilities already paid are excluded.

The price. Rather than reconstructing destination-based rates across every Illinois jurisdiction you sold into over five and a half years, participants pay a simplified rate: 9 percent on general merchandise, 1.75 percent on food for off-premises consumption, medicines, and medical appliances.

The mechanics. Applications are filed through MyTax Illinois, so the applicant must first be registered with the Department and hold a logon. Payment is due with the application, or under an installment plan of six to twenty-four months with automatic withdrawals beginning December 1, 2026. A retailer already under audit is directed to its assigned auditor.

Why the Covered Period Matters for Agents

A transaction count, not a receipts figure, is the nexus prong that binds machine commerce, and the arithmetic does not change across state lines. A metered agent product billed at four cents a call crosses 200 separate Illinois transactions at eight dollars of Illinois revenue. Under the pre-2026 rule, those eight dollars produced the same registration and collection duty that \$100,000 produced.

Illinois removed that prong on January 1, 2026. The amnesty covers January 1, 2021 through June 30, 2026. Read those two dates together: the liability window contains the entire life of the count prong under Illinois's post-Wayfair regime, plus six months of run-off. Whatever else this program is, it is Illinois offering a priced exit from the exposure its own transaction count generated.

That exposure does not decay on its own. As a general matter the limitations period keys off a filed return, so a retailer that registered with no one and filed nothing has not started a clock it can wait out. An operator that tripped the count in 2022 and did nothing is carrying an open-ended item, and the difference between settling it and ignoring it is penalty plus four years of interest.

The 9 Percent Is Not a Discount

This is the part the coverage tends to skip, and it is the part that decides whether you should participate.

Illinois's average combined state and local rate is approximately 8.96 percent. The amnesty rate is 9 percent. That is not coincidence and not generosity — the simplified rate approximates the state 6.25 percent plus an average local component. It is a convenience, so that neither you nor the Department has to rebuild destination sourcing for sixty-six months of history.

So run the comparison honestly. Illinois rates start at 6.25 percent where no local tax applies and reach 10.25 percent in Chicago, higher in a handful of suburban municipalities. A seller whose Illinois customers cluster downstate may have owed 6.25 to 7.25 percent and will pay 9 under amnesty — 175 to 275 basis points more tax than the underlying liability. A seller concentrated in Cook County pays less than it owed.

For most sellers the entire economic case is therefore the penalty and interest waiver, not the rate. For a 2021 liability that is a substantial number and the waiver wins comfortably. For a liability arising in late 2025 it is a much closer call, and for a downstate-weighted book it can go the other way. Compute it. Amnesty is not free money because the word suggests it.

The Limit That Excludes Most of This Audience

The program reaches retailers' occupation tax — a tax on the business of selling tangible personal property at retail. Eligible liabilities under the bulletin are state and local ROT on sales of tangible personal property during the covered period.

Illinois does not impose state-level sales tax on software as a service. An agent operator selling API access, inference, compute, or a hosted platform to Illinois customers has, at the state level, generally not been incurring ROT — and therefore has no eligible liability to amnesty. The program is written for sellers of goods. If your agent sells or facilitates the sale of physical merchandise into Illinois, this is directly yours. If it sells access to software, this is not the relief you are looking for.

Two corollaries follow, and both cut against the reflex to file something just in case.

Chicago is untouched. Chicago's Personal Property Lease Transaction Tax reached 15 percent on January 1, 2026 and does apply to remotely accessed software used in the city. It is a home-rule municipal tax administered by the City, not a retailers' occupation tax. Nothing in a state ROT amnesty resolves a PPLTT position, and an operator with Chicago exposure and no ROT exposure gets nothing here.

Registration is a disclosure. You must be registered with the Department to apply. If you register and then do not complete the application by October 31 — because the arithmetic turned out badly, or because the work ran past ninety days — you have identified yourself to Illinois without buying anything. Decide whether you have an eligible liability, and whether you intend to settle it, before you create the account.

What Agent Operators Should Do Before October 31

Determine whether you have ROT exposure at all. Sales of tangible personal property into Illinois, 2021 through mid-2026. If the answer is none, close this file — Chicago PPLTT is a separate exercise.

If you do, test the threshold year by year. Through 2025 the count prong counts. A low-value, high-volume book can clear 200 transactions without approaching \$100,000, and that is the fact pattern this program exists to clean up.

Price it both ways. Nine percent flat against your actual destination-weighted rate, then set the difference against penalty plus interest from each period. Two numbers, not a slogan.

Watch the sequencing. Registration first, application by October 31, payment with the application or an installment plan you will actually complete. A defaulted plan forfeits the waiver.

Separately, note January 1, 2026. The same Act extended Leveling the Playing Field obligations to service occupation and service use tax. For service-selling agents that prospective change is more consequential than the amnesty, and it is already in effect.

One caveat I have to keep restating: whether transactions initiated by an autonomous agent count toward a state's economic nexus threshold at all remains unresolved, and no state has addressed agent-initiated commerce directly. Illinois is offering to settle liabilities under a test nobody has squarely applied to machine transactions. That is an argument for computing your position carefully, not for assuming the question resolves in your favor.

What to Watch

Whether other states copy the structure. Kentucky dropped its own 200-transaction prong on August 1, 2026 and offered no amnesty alongside it. Illinois paired repeal with a priced exit, which is the more coherent policy: if a legislature has concluded the count swept in sellers with no meaningful presence, leaving five years of liability from that same count on the books is difficult to defend. If Illinois's window produces meaningful collections, expect the pairing to travel.

Knowing which states still count transactions, which of your agent's sales are tangible personal property, and when your Illinois activity crossed a line, is the part of this that does not scale by hand. AgentTax tracks economic nexus thresholds per state and flags when activity approaches one. See how it works at agenttax.io. The Department's own materials — Informational Bulletin FY 2026-28 and the amnesty application — are the controlling text; read them before filing anything.
