An Illinois LLC costs $150 to file with the Illinois Secretary of State, carries a $75 annual report, and pays a flat 4.95% state income tax plus a 1.5% replacement tax on LLCs taxed as partnerships. Illinois lists either members or managers on the public record, so it is not one of the four anonymous-LLC states. Founders who need ownership privacy form a Wyoming or New Mexico anonymous LLC and foreign-qualify into Illinois. This guide covers cost, formation steps, tax, the annual report, and the anonymity path in full.
An Illinois LLC costs $150 to file at formation, plus a $75 annual report each year. Through Anonymousllc.co the total is $297 service fee + $150 state fee = $447 all-in for year one. That $447 covers the state filing, registered agent for year one, an Illinois operating agreement, the EIN, and applications to four or five US partner banks. From year two the recurring cost is the $75 annual report plus $100/year for the registered agent. Founders whose top priority is privacy form a $397 all-in Wyoming anonymous LLC and foreign-qualify into Illinois when local operations require a registered presence.
Forming an Illinois LLC takes six steps: name search, Articles of Organization ($150 state fee), registered agent appointment, operating agreement, EIN, and bank account. The end-to-end timeline is 5-10 business days with Anonymousllc.co. The Illinois Secretary of State accepts the Articles of Organization within 1-3 business days. Anonymousllc.co runs the name check against the state database, files the Articles, obtains the EIN, and submits bank applications in parallel. Springfield is the state capital, and all LLC filings route through the Secretary of State's business services division.
No. Illinois requires either members or managers (or both) to be disclosed on public state records, so ownership appears in the Secretary of State database. Illinois is not one of the four anonymous-LLC states. The four states that keep members and managers off the public record are Wyoming, New Mexico, Delaware, and Nevada. Founders who need true anonymity form the LLC in one of those states and foreign-qualify into Illinois when they have local operations. The most common path is a Wyoming anonymous LLC that foreign-qualifies into Illinois, keeping ownership private while maintaining a compliant Illinois registration.
An Illinois LLC pays a flat 4.95% personal income tax on its pass-through profit, plus a 1.5% replacement tax on LLCs taxed as partnerships. The IRS treats a single-member LLC as a disregarded entity and a multi-member LLC as a partnership by default. Profit passes through to the owners' personal returns; there is no separate LLC income tax at the federal level. An S-corporation election, filed on IRS Form 2553, saves self-employment tax once net income clears the $40,000-$60,000 range. Non-resident owners with a foreign-owned single-member LLC file Form 5472 with a pro-forma Form 1120 each year.
Illinois requires an annual report with a $75 fee, filed with the Secretary of State each year. The report updates the registered agent, principal office address, and manager information on the public record. Missing the deadline moves the LLC out of good standing and triggers administrative dissolution, which retroactively voids the liability shield that protects personal assets. Anonymousllc.co tracks the filing date and submits the $75 report as part of the registered agent subscription, so the deadline never passes unnoticed.
Yes. Every Illinois LLC must maintain a registered agent with a physical street address in Illinois to receive service of process and state mail. A PO Box does not satisfy the requirement. Anonymousllc.co provides Illinois registered agent service at $100/year, included free in year one of any formation package. The agent's address appears on the public filing instead of the owner's home or business address, and the service includes mail scanning, forwarding, and annual report reminders. Full details are on the Illinois registered agent page.
Yes. Illinois is one of the states that permits statutory series LLCs, letting a single parent LLC hold multiple protected series under one filing. Each series shields its own assets from the liabilities of the others. The standard $150 state filing fee applies to the parent series LLC, and the $75 annual report is due each year. A series LLC operating agreement needs series-specific provisions that define which assets and members belong to each series. Anonymousllc.co drafts the series-specific operating agreement provisions when a client forms an Illinois series LLC.
An Illinois LLC costs $447 all-in for year one and lists ownership publicly, while a Wyoming anonymous LLC costs $397 all-in and keeps members and managers off the record. Wyoming also charges no state income tax against Illinois's flat 4.95%. New Mexico is the lowest-cost anonymous option at $347 all-in with no annual report and no annual fee. Illinois still makes sense for a business with a physical Illinois presence, Illinois employees, or Illinois real estate. Many founders combine both: a Wyoming holding LLC that owns the Illinois operating LLC, keeping the ultimate owner private while the Illinois entity handles local business.
Yes. Non-US residents form Illinois LLCs without an SSN, ITIN, visa, or any visit to the United States. Illinois places no citizenship or residency condition on LLC ownership. Anonymousllc.co files the Articles of Organization, obtains the EIN by fax as third-party designee in 5-7 days, provides the Illinois registered agent and address, and submits US bank applications remotely. The founder completes the entire process from abroad over WhatsApp. Non-resident owners then file Form 5472 with a pro-forma Form 1120 for the LLC each year.
An Illinois LLC is fully operational in 5-10 business days end-to-end. The Secretary of State accepts the Articles within 1-3 business days, the EIN follows in 5-7 days for non-residents, and bank approval lands 8-10 days after the EIN. The steps run in parallel wherever the sequence allows. Day 0 is a 5-minute WhatsApp intake; Anonymousllc.co files the Articles the same day and starts the EIN the moment the state stamp arrives. Bank applications go to four or five partner banks at once, so a decline at one institution does not restart the clock.
Form a Wyoming or New Mexico anonymous LLC and foreign-qualify it into Illinois. The anonymous LLC holds ownership off the public record, and the Illinois foreign registration lists the anonymous entity rather than the individual owner. The Illinois registered agent keeps the owner's personal address off state filings, but Illinois still discloses members or managers of a domestic Illinois LLC. The full privacy solution routes ownership through Wyoming or New Mexico. Anonymousllc.co structures the Wyoming anonymous LLC plus Illinois foreign qualification as a single engagement for founders who operate in Illinois but need to keep ownership private.
