For non-US owners of a Illinois LLC
Foreign-Owned Illinois LLC: State Report, Tax and IRS Filing
Your LLC is formed in Illinois and you live outside the US. Two sets of rules apply every year: Illinois's report and tax, and the IRS filing for foreign-owned LLCs. Here are both, from the state's own sources and the IRS.
Quick answer
What does a foreign-owned Illinois LLC have to file each year?
With Illinois: Annual Report (Form LLC-50.1). Fee: US$75. Due: Before the first day of the LLC's anniversary month; it can be filed within the 60 days before that date. With the IRS: Form 5472 with a pro forma Form 1120 for any year with a transaction between the LLC and its foreign owner, with a US$25,000 penalty if missed.

The Illinois side: report, fee and tax
Before the IRS side, the state. Illinois's requirements, from official Illinois sources (Illinois official source): State figures checked October 28, 2026.
| Item | Illinois |
|---|---|
| Yearly report | Annual Report (Form LLC-50.1) |
| Fee | US$75. US$75, plus US$50 for each series with a certificate of designation. |
| Due | Before the first day of the LLC's anniversary month; it can be filed within the 60 days before that date. |
| State tax | None found on the official pages checked. |
| If it is late | US$100 penalty if not filed within 60 days after the due date; administrative dissolution if still unfiled 120 days after the LLC becomes delinquent. |
Easy to miss: The report is due before the anniversary month starts, not at the end of it.
A yearly calendar for a Illinois LLC
- State: Annual Report (Form LLC-50.1): Before the first day of the LLC's anniversary month; it can be filed within the 60 days before that date.
- IRS: Form 5472 with the pro forma Form 1120, normally by April 15 for a calendar-year LLC (Form 7004 extends it)

Federal filings, whatever Illinois requires
| Filing | When | Source |
|---|---|---|
| Form 5472 with a pro forma Form 1120 | Each year the LLC has a reportable transaction with its foreign owner; US$25,000 penalty if missed | IRS |
| BE-13 | Generally within 45 days of a foreign person setting up or buying a US business | BEA rule |
| Form 1040-NR | Only if the LLC has income effectively connected with a US trade or business | IRS |
None of these depend on the state. A Illinois LLC files them on the same terms as an LLC formed anywhere else.
