You can start an Illinois LLC without living in the United States, without a Social Security Number, and without ever traveling to Illinois. The process is: choose an available name with an LLC designator, appoint a registered agent with an Illinois street address, and file Articles of Organization (Form LLC-5.5) with the Illinois Secretary of State for a $150 fee. Online filings are typically approved in 7 to 10 business days. After approval: create an operating agreement, get a free EIN from the IRS (foreign founders apply on Form SS-4 by fax or mail), and open a US business bank account. Then your Illinois LLC is ready to trade.
Illinois suits foreign founders with real Midwest ties: Chicago is a major market, formation costs a flat $150, and there is no publication requirement. The trade-offs are a $75 annual report every year before your anniversary month, and a flat 4.95% state income tax on pass-through business income. Below are all seven steps with the real 2026 fees, the rules that matter for non-US founders, and the compliance to keep up afterward.

How much does it cost to start an Illinois LLC?
The mandatory state cost is simple. As of October 2026, the Articles of Organization fee is a flat $150, online or by mail, and the annual report costs $75 every year. Older guides quoting $500 or $600 are using an outdated fee schedule.
| Item | DIY cost | With Registered Agents Inc |
|---|---|---|
| Articles of Organization state fee | $150 | $150 |
| Service fee | $0 | $100 (check current pricing) |
| Registered agent, year 1 | $0 (yourself, needs IL address) or roughly $100 to $175 per year for a service | Included: 1 year of registered agent service free in the $100 bundle |
| EIN from the IRS | Free | Free |
| Operating agreement | $0 (write it yourself) | Often included in templates |
| Typical first-year total | $150 to $325 | $250 ($100 + $150 state fee) |
Optional extras: $100 expedited processing (about 24 hours), a $25 name reservation for 90 days, and a $25 Certificate of Good Standing if a bank or partner asks for one.
See the full cost breakdown of forming an LLC: foreign founders usually also need a registered agent service and, in Chicago, city licensing.
The 7 steps to start an Illinois LLC
Step 1: Choose your LLC name
Illinois naming rules are straightforward but strict. Every LLC name must contain “Limited Liability Company”, “LLC”, or “L.L.C.” as the designator. The name must be distinguishable from every business name already on file with the Secretary of State, so “Lakeview Marketing LLC” will be rejected if something confusingly similar already exists. Punctuation changes and extra words like “The” usually do not make a name distinguishable.
The name also cannot suggest a government agency (no “Treasury”, “FBI”) or contain words like “Corporation”, “Inc.”, “Corp.”, “Ltd.”, or “Co.”, which signal a different entity type. Words tied to regulated industries, such as “Bank”, “Trust”, “University”, or “Attorney”, need authorization before the state will approve them.
Before you commit, check the Illinois Secretary of State’s business entity search. You can reserve a name for 90 days for $25 (Form LLC-1.15), and should also search the USPTO trademark database: clearing the state registry does not stop a federal trademark claim.
Step 2: Appoint a registered agent
Every Illinois LLC must have a registered agent with a physical Illinois street address. A P.O. box or mailing-only address does not qualify. The agent must be available at that address during normal business hours to receive service of process, lawsuits, and official state correspondence, and the agent must consent to the appointment.
For a non-US founder this is the one step you cannot do for free: without an Illinois address you cannot serve as your own agent. A service keeps your address off public records, forwards legal mail, and tracks filing deadlines. Read our explainer on whether you really need a registered agent for the full picture.
Step 3: File your Articles of Organization
Filing Form LLC-5.5 (Articles of Organization) with the Illinois Secretary of State is the legal act that creates your LLC. You file it online through the Secretary of State’s business services system, or by mailing the paper form to the Department of Business Services in Springfield. The fee is $150 either way, as of October 2026.
The form asks for:
- The LLC name, exactly as you want it registered
- The principal office address (this can be outside Illinois, even outside the US)
- The registered agent’s name and Illinois street address
- Whether the LLC is member-managed or manager-managed
- The organizer’s name and signature
- The effective date: on filing, or a delayed date up to 60 days later
Online filings clear in 7 to 10 business days; mailed filings take several weeks. The $100 expedite fee brings processing to about 24 hours. Once approved, the state issues a Certificate of Organization: save it, because banks and payment processors ask for it.
To skip the paperwork, form your Illinois LLC with Registered Agents Inc for $100 plus the $150 state fee. The bundle covers the filing, a domain name, a website, and one year of free registered agent service. Add-on phone and email tools are $5 per month each, so check current pricing first.
Step 4: Create an operating agreement
Illinois does not require an operating agreement, but skipping it is a mistake. It sets out ownership, profit splits, decision-making, and what happens when a member leaves or dies. For single-member LLCs it also reinforces the separation between you and the company, which matters if your liability protection is ever questioned.
Banks often ask for it, and co-founders need the rules in writing before money starts flowing. You sign it and keep it with your company records; it is never filed with the state. Use a reputable template, and have an attorney review it if you have co-founders or an unusual arrangement.
Step 5: Get an EIN from the IRS
The Employer Identification Number is your LLC’s federal tax ID. Banks require it to open an account, Stripe and other processors ask for it, and you cannot file federal tax forms without it. It is always free from the IRS; never pay a third party for one.
With an SSN or ITIN, you apply online and get the EIN immediately. Without one, foreign founders must file IRS Form SS-4 by fax or mail and wait, typically 4 to 6 weeks. Leave the SSN/ITIN field blank, and copy the LLC name exactly as it appears on your approved Articles of Organization: name mismatches are the most common reason foreign EIN applications get rejected.
Step 6: Open a US business bank account
Keep business money separate from personal money from day one. Commingling funds weakens your liability protection and makes taxes and bookkeeping far harder than they need to be.
Traditional banks usually require an in-person visit with your passport, Certificate of Organization, operating agreement, and EIN letter. Many non-US founders start instead with a fintech account (Mercury, Wise, Relay): US routing and account numbers, remote onboarding for foreigners, Stripe integration. Compare them in our guide to opening a US bank account as a non-resident.
Step 7: Get licenses and register for taxes
Illinois has no statewide general business license, so what you need depends on where you operate and what you sell.
- Local licenses. Cities and counties set their own rules, so check every municipality where you have a presence. The City of Chicago requires most businesses to hold a business license (Department of Business Affairs and Consumer Protection, BACP), even online businesses.
- Professional licenses. Regulated activities (plumbing, roofing, electrical, health care, food service) need state-level licenses from the relevant Illinois agency.
- Sales tax. If you sell taxable goods or services in Illinois, register through the Illinois Department of Revenue’s MyTax Illinois portal. The state base rate is 6.25% (October 2026), with local add-ons raising the combined rate; verify your exact location’s rate.
- Employer taxes. Hiring employees triggers unemployment insurance and withholding registrations, also via MyTax Illinois.
Starting an Illinois LLC as a non-US founder
Illinois and federal formation rules treat foreign owners the same as domestic ones: no citizenship, residency, or Illinois-address requirement for members or managers. The principal office address on your filing can be your address abroad.
Five things foreign founders should plan for:
- Registered agent is mandatory. You need an Illinois street address for service of process, so budget for a service unless you have a trusted person in Illinois. Registered Agents Inc includes the first year in its $100 formation bundle; standalone service runs roughly $100 to $175 per year.
- The EIN takes patience. Without an SSN or ITIN, Form SS-4 goes by fax or mail and takes 4 to 6 weeks. File it the day your Articles of Organization are approved so the wait runs while you handle everything else.
- You may need an ITIN too. The EIN covers the company; if you personally receive US-source income or must file a US tax return, you will likely need an Individual Taxpayer Identification Number (Form W-7), a separate application from the EIN.
- Form 5472 and pro-forma Form 1120. A single-member LLC 100% owned by a foreign person is a disregarded entity for tax, but the IRS still requires Form 5472 (reportable transactions with the foreign owner) attached to a pro-forma Form 1120 every year, even with zero income. The penalty is $25,000. Calendar it before your first year ends.
- The US tax treaty with your country matters. Whether your LLC’s income faces US federal tax depends on the income type and the treaty between the US and your home country. Illinois’s 4.95% flat tax applies to Illinois-source pass-through income. Get a cross-border accountant before you scale.
Keeping your Illinois LLC compliant
Two recurring state obligations keep your LLC in good standing:
- Annual report, $75 per year. Due before the first day of your anniversary month (the month the state approved your Articles of Organization). File online or by mail; missing it triggers a $100 late penalty, and long-term non-filing can lead to administrative dissolution. Your first report is due in the year after formation.
- Registered agent maintenance. If your agent changes, file the change with the Secretary of State promptly. A stale agent means missed lawsuits and missed state notices.
Beyond that, stay current on federal filings (Form 5472/pro-forma 1120 for foreign-owned single-member LLCs), renew local licenses, and file any Illinois tax returns your activities require. When you are done, dissolve the LLC properly: abandoning it means back fees and penalties if you ever reinstate.
Illinois vs Wyoming for a non-US founder
Wyoming is the default recommendation for most foreign founders: cheaper to form and maintain, with no state income tax. But Illinois can be right when your business has a genuine Illinois footprint. The comparison below uses each state’s published fee schedule as of October 2026.
| Illinois | Wyoming | |
|---|---|---|
| Formation filing fee | $150 | $100 |
| Annual report / license tax | $75 per year | $60 minimum per year |
| State income tax | 4.95% flat on pass-through income | None |
| Annual report due | Before anniversary month | First day of anniversary month |
| Publication requirement | None | None |
| Registered agent | Illinois street address required | Wyoming street address required |
| Member privacy | Members not required on public filing, but less privacy-oriented than Wyoming | Strong: no member listing on public filing |
Choose Illinois with a physical presence there: a Chicago office, an Illinois warehouse, Illinois employees, or a business tied to the Chicago market. Forming in Illinois avoids foreign qualification, which costs $150 plus its own annual report.
Choose Wyoming for a location-independent online business with no Illinois presence: cheaper every year and no income tax.
Avoid the common mistake: do not run a Chicago office on a Wyoming LLC without foreign-qualifying it in Illinois. The back fees for operating unregistered dwarf the $150 qualification cost.
FAQ
How much does it cost to start an LLC in Illinois?
The state filing fee is $150, online or by mail, as of October 2026. Registered Agents Inc charges $100 plus the state fee, which includes the filing, a domain name, a website, and one year of free registered agent service. Budget $75 per year for the annual report. Older guides quoting $500 or $600 are describing an outdated fee schedule.
How long does it take to get an LLC in Illinois?
Online filings clear in 7 to 10 business days; mailed filings take several weeks. The $100 expedite fee cuts processing to about 24 hours. Full setup takes longer, especially the 4 to 6 week EIN wait for foreign founders filing by fax or mail.
Can a foreigner start an LLC in Illinois without an SSN?
Yes. Illinois requires no SSN, ITIN, US residency, or citizenship to form or own an LLC. You do need a registered agent with an Illinois street address. The only step where the lack of an SSN matters is the EIN: file Form SS-4 by fax or mail instead of using the IRS online application.
Does Illinois require an operating agreement for an LLC?
No, but you should still create one. It documents ownership, profit distribution, and decision-making, strengthens your liability protection, and banks frequently request it when you open an account. For multi-member LLCs, skipping it invites future disputes that an agreement would have settled.
Do I need a business license for my Illinois LLC in Chicago?
Illinois has no statewide general business license, but the City of Chicago requires most businesses to hold a license through the Department of Business Affairs and Consumer Protection (BACP), even if you operate from outside the city. Other Illinois cities and counties have their own rules, so check each locality. Selling taxable goods also requires a sales tax registration with the Illinois Department of Revenue.
When is the Illinois LLC annual report due?
It is due before the first day of your LLC’s anniversary month, the month the state approved your Articles of Organization. An LLC formed in June must file by May 31 each year. The fee is $75, with a $100 late penalty. The first report is due in the calendar year after formation.

Conclusion
Starting an Illinois LLC is seven steps: pick a compliant name, appoint a registered agent with an Illinois street address, file the Articles of Organization for $150, write an operating agreement, get your free EIN, open a US bank account, and handle licenses and taxes. Foreign founders can do nearly all of it remotely; the only waiting game is the 4 to 6 weeks for an EIN by fax or mail, and the ongoing discipline is the $75 annual report each year.
To skip the paperwork, form your Illinois LLC with Registered Agents Inc for $100 plus the $150 state fee, including the domain, website, and a full year of free registered agent service. Check current pricing before ordering, and calendar your annual report and Form 5472 deadlines from day one.
