Yes—some Illinois sellers can use the 2026 Illinois Remote Retailer Tax Amnesty Program. It is designed for qualifying remote retailers that had Illinois Retailers’ Occupation Tax liabilities on eligible transactions during the period January 1, 2021, through June 30, 2026. To receive the amnesty, a seller must apply electronically, report all eligible transactions, and pay the required Illinois State and local retailers’ occupation taxes during the amnesty period, which ends October 31, 2026.
The program can waive applicable penalties and interest connected with eligible liabilities, but it is not a general forgiveness of the underlying tax. Eligibility depends on whether the business was a qualifying remote retailer, met Illinois’s applicable tax-remittance threshold, and fully reported and paid its eligible liability. Sellers should not assume that marketplace sales, an Illinois registration, or a previously filed return automatically answers those questions. Sales Tax Compliance USA can help review the transaction history, determine the filing position, and handle the state compliance work.
Key takeaways
- The eligible transaction period is January 1, 2021, through June 30, 2026.
- The application, filing, and payment deadline is October 31, 2026.
- Qualifying sellers must be registered with Illinois and have active MyTax Illinois access.
- The program can waive applicable penalties and interest, but not the underlying eligible tax.
- Beginning in 2026, Illinois uses the $100,000 gross-receipts threshold rather than the former 200-transaction threshold.
Who can use the Illinois remote-retailer amnesty?
The program applies to a qualifying remote retailer—an out-of-state retailer selling tangible personal property to Illinois purchasers without a physical presence in Illinois that met Illinois’s tax-remittance threshold for all or part of the eligibility period. The relevant tax is Illinois Retailers’ Occupation Tax, including State and local retailers’ occupation taxes administered by the Illinois Department of Revenue.
For periods beginning on or after January 1, 2026, Illinois identifies a remote retailer’s threshold as $100,000 or more in cumulative gross receipts from retail sales to Illinois purchasers during the preceding four calendar quarters. For earlier periods covered by the amnesty, the applicable threshold is determined under the rules for that period. Because the measurement period and transaction facts matter, a seller should analyze each period rather than apply the current rule mechanically to every historical sale.
Amazon, Shopify, Etsy, and Walmart sellers are not automatically excluded because they sell through a marketplace or online store. The important questions are who made the retail sale, whether the seller met the Illinois threshold, whether the marketplace collected tax, and whether any Illinois tax remained the seller’s responsibility. Those questions are especially important for sellers using fulfillment inventory in or around Illinois; see Amazon FBA Sales Tax in Illinois for the physical-presence issue.
Which tax periods and liabilities qualify?
The statutory eligibility period is January 1, 2021, through June 30, 2026. The amnesty period—the time to apply, file, and pay—is August 1, 2026, through October 31, 2026. The program addresses eligible State and local retailers’ occupation taxes due on qualifying transactions occurring during the eligibility period.
The underlying tax is not erased. Instead, a qualifying participant reports and pays the eligible tax using the program’s simplified retailers’ occupation tax rate or otherwise applicable State and local rates, as required for the transactions. The Illinois Department of Revenue’s program materials identify simplified rates of 9% for general merchandise historically subject to the 6.25% State rate and 1.75% for items historically taxed at the lower rate. Product classification and the transaction facts still matter.
Amnesty does not automatically cover every Illinois tax, every period, or every type of liability. It is aimed at Retailers’ Occupation Tax liabilities administered by the Department. A seller with use tax, service occupation tax, income tax, local obligations outside the program, or assessed liabilities involving unusual facts should confirm the treatment with the Department or obtain professional advice before filing.
What penalties and interest can the program waive?
When a seller satisfies the program’s requirements, applicable penalties and interest associated with the eligible tax may be waived. The benefit is tied to the eligible transactions and periods covered by the program; it is not permission to omit transactions or pay only the amount the seller considers convenient.
The seller generally must report all eligible transactions and remit all required State and local retailers’ occupation tax during the amnesty period. If a business files incomplete information, fails to pay the required amount, or leaves eligible transactions out of the submission, it may not receive the intended amnesty treatment for the omitted liability.
Amnesty can also provide protection from civil or criminal prosecution for the period for which amnesty is granted under the governing law. That protection should not be read as immunity for unrelated conduct, inaccurate filings, or periods and taxes outside the program.
What is the 2026 deadline?
The Illinois Remote Retailer Tax Amnesty Program runs through October 31, 2026. The application, required electronic filings, and payment must be completed during the amnesty period. Waiting until the final day creates practical risk because registration, account access, transaction analysis, return preparation, and payment processing may take time.
The Illinois Department of Revenue states that applications and filings are submitted electronically through MyTax Illinois. A seller that expects to participate should establish or verify its MyTax Illinois access and resolve registration questions before beginning the return work.
If your business cannot determine its eligibility or liability before the deadline, the exact position depends on your circumstances—confirm with the Illinois Department of Revenue, or talk to Sales Tax Compliance USA and we will check it for you.
What changed for Illinois remote sellers in 2026?
Illinois removed the 200-transaction threshold for remote retailers and marketplace facilitators beginning January 1, 2026. The relevant remote-retailer threshold is now based on $100,000 or more in cumulative gross receipts from sales to Illinois purchasers, measured under the applicable Illinois rules.
The change matters to sellers that previously stayed below the dollar threshold but exceeded the transaction-count threshold. For periods beginning in 2026, the number of transactions alone is no longer the stated trigger for requiring remote retailers and marketplace facilitators to collect and pay destination-based Illinois tax. A seller that reaches the $100,000 threshold can become liable for applicable State and local retailers’ or service occupation taxes on Illinois sales.
Illinois also uses destination-based rules for covered remote sales. That means the customer’s Illinois delivery location can affect the applicable State and local tax treatment. Sellers should preserve order destinations, gross receipts, product classifications, marketplace collection records, refunds, and tax charged rather than relying only on a bank deposit total. See Economic Nexus in Illinois for the broader nexus analysis.
Can an unregistered seller participate?
Not without addressing registration. Illinois Department of Revenue materials state that remote retailers meeting the $100,000 tax-remittance threshold must be registered with the Department and have an active MyTax Illinois logon to participate in the 2026 program. An unregistered seller should therefore begin with registration and account-access steps, not assume that amnesty permits anonymous payment.
Registration does not by itself determine the amount owed or guarantee that every historical period qualifies. The seller still needs to determine when it met the threshold, identify eligible Illinois transactions, account for marketplace-collected tax, and submit the required returns or amnesty filings.
For practical background, review Sales Tax Registration in Illinois and Sales Tax Permit in Illinois. Registration questions can be fact-specific, so a seller that has never held an Illinois account should address them promptly with the Department or a qualified compliance service.
How sellers calculate, report, and pay the liability
A defensible calculation starts with Illinois destination data and a complete sales population for January 1, 2021, through June 30, 2026. Separate Illinois orders from other orders, identify taxable tangible personal property, remove valid cancellations and refunds, classify reduced-rate products correctly, and reconcile the result to marketplace and direct-store records. Then compare tax collected by a marketplace or another party with the tax that remains the seller’s responsibility.
The program provides a simplified rate structure for qualifying eligible transactions. Illinois materials identify 9% for general merchandise historically subject to the 6.25% State rate and 1.75% for items historically taxed at the lower rate. These figures should not be applied blindly: product type, transaction date, destination, exemptions, refunds, and the applicable filing instructions can affect the correct treatment.
Applications and filings are made electronically through MyTax Illinois, and payment must be made during the amnesty period. Sellers should retain the transaction schedules, marketplace reports, exemption documentation, refund support, calculation workpapers, and payment confirmations. For ongoing obligations after the amnesty period, see Sales tax filing in Illinois.
What if the seller skips amnesty or cannot pay in full?
A seller that does not participate does not receive the program’s waiver merely because it could have qualified. Unpaid Illinois tax can remain subject to the Department’s ordinary collection, assessment, penalty, and interest rules. The time Illinois may have to assess a liability depends on the return, registration, filing history, and other facts; see How far back can a state assess unpaid sales tax? for the general issue.
Missing the program deadline can also mean losing the opportunity to resolve eligible liabilities under the simplified amnesty process. It does not necessarily eliminate the underlying tax obligation. Sellers should not wait for an audit notice before assembling their records.
If the business cannot pay the full amount, it should contact the Illinois Department of Revenue promptly and ask about available payment arrangements or other collection options. Do not assume that an installment arrangement preserves amnesty or waives penalties and interest unless the Department confirms that in writing. The exact position depends on your circumstances—confirm with the state, or talk to us and we will check it for you.
Can Illinois tax credits pay the amnesty liability?
A seller should not assume that an Illinois tax credit can be used as a substitute for the required amnesty payment. Credits may be limited by the tax type, account, period, refund or credit procedures, and the Department’s instructions for the program. A credit from one Illinois tax account or period may not automatically offset an amnesty liability.
Before reducing the payment by a credit, identify the credit’s source, confirm that it is valid and available, and obtain confirmation from the Illinois Department of Revenue that it may be applied to the specific amnesty liability. If the credit is based on marketplace-collected tax, refunds, bad debts, exemptions, or prior overpayments, preserve the records supporting it.
Until the Department confirms the treatment, the safer approach is to calculate the required amnesty payment independently and treat any credit as a separate issue. A payment shortfall could affect whether the seller receives the intended waiver.

Frequently asked questions
Can Illinois sellers use the 2026 remote-retailer amnesty?
Some can. The program is for qualifying remote retailers with eligible Illinois Retailers’ Occupation Tax liabilities from January 1, 2021, through June 30, 2026, who apply, report all eligible transactions, and pay during the August 1 through October 31, 2026 amnesty period.
Do Amazon, Shopify, Etsy, and Walmart sellers qualify automatically?
No. Selling through a marketplace or online store does not automatically establish or eliminate eligibility. The seller must analyze its Illinois threshold, transaction ownership, marketplace tax collection, taxable products, and remaining liability.
Can an unregistered remote seller participate?
A qualifying seller must address Illinois registration and have an active MyTax Illinois logon to participate. An unregistered seller should resolve those requirements before attempting to submit an amnesty filing.
Does amnesty eliminate the Illinois tax itself?
No. The seller must report and pay the eligible State and local retailers’ occupation tax. The principal benefit is the potential waiver of applicable penalties and interest when the program requirements are satisfied.
What is the final deadline?
The 2026 Illinois Remote Retailer Tax Amnesty Program ends October 31, 2026. The electronic application, required filings, and payment must be completed during the amnesty period.
What happens if a seller cannot pay the full amount?
Contact the Illinois Department of Revenue promptly about payment options. Do not assume an installment arrangement preserves the amnesty waiver; confirm the effect with the Department before relying on it.
Can an Illinois tax credit offset the amnesty payment?
Not automatically. Credit use depends on the credit’s type, account, period, and the Department’s instructions. Confirm with Illinois before reducing the amnesty payment by a credit.
