Indiana: A Clean Slate — If You Find Everything You Owe
Indiana’s amnesty window is open to any business or individual with unresolved tax exposure from before 2024 — not just registered filers. Pay the tax you owe, and the state waives penalties, interest, and collection fees. Payment plans are available through June 2027 for anyone who can’t pay in full by September 9.
One thing to know: Indiana’s own eligibility tool (INTIME) only checks years you were already registered. If you had Indiana sales before you registered — or gaps in your filing history — that exposure won’t show up on the state’s tool.
- Every DOR-administered tax type is covered
- Excluded only if you participated in the 2005 or 2015 Indiana amnesty
- Payment plans available through June 2027

Illinois: One Flat Rate, No Jurisdiction-by-Jurisdiction Math
If you’ve shipped taxable goods into Illinois since 2021 without a physical presence there, this program lets you resolve it at a simplified flat rate — 9% of gross receipts for general merchandise — instead of calculating local rates jurisdiction by jurisdiction. Interest, penalties, and prosecution risk are off the table.
This program is built for registered remote retailers specifically. If you’re not sure whether that’s you, the quiz below will tell you in under two minutes.
- Filing period: January 1, 2021 – June 30, 2026
- One flat statewide rate, no local-rate calculations
- Available only to registered remote retailers in good standing
