Quick Takeaways
- Illinois taxes cigarettes through both the Cigarette Tax Act and the Cigarette Use Tax Act, and licensed distributors prepay the tax using cigarette tax stamps that are later passed through the supply chain.
- Effective January 1, 2026, Illinois requires all cigarette tax returns and supporting schedules to be filed electronically, and payments must also be submitted electronically.
- If you are a distributor, manufacturer, stamping distributor, secondary distributor, retailer, or unlicensed purchaser, the reporting rules, forms, and deadlines differ — so it helps to know your exact role before filing.
- Illinois also requires annual license fees, bonds in some cases, and electronic payment for cigarette tax stamp purchases through Electronic Funds Transfer (EFT).
Why This Topic Matters
Tax rules for tobacco products can feel overwhelming, especially when the requirements depend on whether you are a distributor, retailer, manufacturer, or just someone handling an unstamped purchase. The good news is that Illinois lays out the system clearly once you know how the tax works and which forms apply to your situation.
How Illinois Cigarette Taxes Work
Illinois says the Cigarette Tax Act imposes a tax on the occupation of selling cigarettes at retail. Licensed distributors prepay the tax by buying stamps and affixing them to each cigarette package. The distributor then collects the tax from the retailer, and the retailer passes it on to the consumer in the cigarette sale price. Illinois also has a separate Cigarette Use Tax Act, which taxes the privilege of using cigarettes in Illinois and duplicates the cigarette tax provisions.
What counts as a cigarette?
Illinois defines a cigarette as any roll for smoking made wholly or partly of tobacco, regardless of size or shape, and regardless of flavoring or other ingredients, with a paper or similar wrapper that is not tobacco.
What about little cigars?
Illinois says little cigars are also taxed. In fact, little cigars sold in packages of 20 or 25 must be affixed with a cigarette tax stamp. Distributors that sell both cigarettes and little cigars are treated as stamping distributors and must meet the licensing and filing requirements that apply to both cigarette and tobacco products distributors.
Important 2026 Change: Electronic Filing Is Now Required
This is one of the most important updates on the page. Illinois says that effective January 1, 2026, Public Act 104-0006 requires all cigarette tax returns and supporting schedules to be filed electronically, and payments must also be submitted electronically. Illinois points taxpayers to Informational Bulletin FY 2026-07, Changes to the Cigarette Tax for more details.
That means if you are used to paper-based filing, you need to plan ahead now.
Tax Rate and Deductions
Illinois tells taxpayers to use the Tax Rate Database to locate the current rate for both Cigarette Tax and Cigarette Use Tax.
Illinois also lists allowable deductions, including:
- sales out of state,
- cigarettes and little cigars returned to manufacturers,
- cigarettes and little cigars lost through fire, theft, or similar events if properly documented,
- sales to residents incarcerated in penal institutions and to patients of state-operated mental health facilities when manufactured as part of a correctional industries program,
- sales to U.S. military personnel through officially recognized agencies physically located at military bases, and
- direct sales to U.S. veteran’s hospitals.
Who Needs to Register, License, or Bond?
If you are a cigarette distributor, Illinois says you must file Form REG-1, Illinois Business Registration Application, pay an annual fee of $250, and post a $2,500 bond for each location. You can also register using MyTax Illinois.
Illinois also notes that a Cigarette Transporter Permit may be required using Form IDR-169 if unstamped cigarettes are:
- purchased for resale in another state,
- transported through Illinois but not sold in Illinois, or
- delivered to another state.
Illinois is clear that those cigarettes cannot be returned to Illinois.
Retailers
Retailers of cigarettes and tobacco products must obtain a Cigarette and Tobacco Products Retailer License. Illinois says this license also allows retailers to sell electronic cigarettes. Retailers must pay an annual license fee per retail location, and the initial license application fee must be submitted electronically. The annual renewal fee must also be submitted electronically using MyTax Illinois.
Filing and Payment Requirements by Taxpayer Type
Illinois gives different forms depending on your role. Here’s a simplified view:
| Taxpayer type | Required form(s) | Due date / timing |
|---|---|---|
| In-state cigarette distributor | Form RC-6, Cigarette and Little Cigar Revenue Return | Filed electronically, due monthly by the 15th day of the following month. |
| Out-of-state cigarette distributor | Form RC-6-A, Out-of-State Cigarette and Little Cigar Revenue Return | Filed electronically, due monthly by the 15th day of the following month. |
| Distributor importation reporting | Form RC-25, Cigarette Importation Report | Due by the first business day of the following month. |
| Stamp order | Form RC-1-A, Cigarette Tax Stamp Order-Invoice | Filed as needed to purchase stamps. |
| Manufacturers or importers | Form RC-36 Schedule CM | Due by the 5th day of the month following the transaction. |
| Unstamped little cigar sticks | Form RC-55, Unstamped Little Cigar Sticks Tax Return | Filed electronically, due monthly by the 15th day of the following month. |
| Stamping distributors | RC-6, RC-6-A, RC-25, RC-1-A, RC-36 Schedule CM, RC-55, and Form TP-1 | Form TP-1 is due by the 15th day of the month following the month the tobacco products were sold or otherwise disposed. |
| Secondary distributors | Form RCS-1, Secondary Distributors/Manufacturer Representatives Report | Filed in MyTax Illinois, due monthly by the 15th day of the following month. |
| Unlicensed individuals | Form RC-44, Cigarette Use Tax Return | Due within 30 days of the purchase. Paper filing only. |
What If You’re Not a Licensed Business?
If you are an unlicensed individual who purchases unstamped cigarettes from a seller, Illinois says you must file Form RC-44, Cigarette Use Tax Return, on a per-purchase basis within 30 days of the purchase. Illinois also says you cannot report cigarette use tax electronically; you must file the paper return.
That matters because this tax is still due even if you are not a distributor or manufacturer.
Electronic Filing and Payment Options
Illinois says one electronic filing option is direct transmission using software you develop or purchase. Another option is MyTax Illinois, which the state says can be used to file most cigarette tax and cigarette use tax returns and reports. All cigarette tax stamp purchases must be paid by Electronic Funds Transfer (EFT).
For businesses trying to streamline compliance, this means your filing workflow should be digital-first.
Common Mistakes to Avoid
1) Waiting too long to switch to electronic filing
Since Illinois requires electronic filing and electronic payments beginning January 1, 2026, paper processes can create avoidable delays or compliance issues.
2) Using the wrong form for your role
A distributor, retailer, manufacturer, and unlicensed purchaser do not file the same forms.
3) Missing monthly due dates
Most cigarette tax filings are due monthly, often by the 15th day of the following month.
4) Forgetting local tax rules
Illinois says cigarette taxes may exist in both home rule and non-home rule municipalities, but the Department of Revenue does not collect locally imposed cigarette taxes.
5) Overlooking stamp, bond, or license requirements
Distributor and retailer obligations can include stamps, bonds, annual fees, and renewals. Missing any one of them can create a bigger compliance problem than the tax return itself.
Pro Tips
- Confirm your taxpayer category first: distributor, retailer, manufacturer, stamping distributor, secondary distributor, or unlicensed purchaser.
- Put every due date on a calendar, especially the 15th day deadlines and the first business day deadline for importation reports.
- If you buy cigarette tax stamps, make sure your payment method is set up for EFT.
- Use MyTax Illinois now so the 2026 electronic filing requirement does not catch you off guard.
- Keep support for deductions such as out-of-state sales, returns to manufacturers, and documented losses.

Illinois cigarette tax compliance is very form-driven, but it becomes much easier when you map the rules to your role and build a filing calendar around the monthly deadlines. The biggest takeaway for 2026 is simple: go electronic, keep your records clean, and make sure the right forms and payments are submitted on time.
