What filing yourself in Illinois actually involves

The state fee is the easy part. Here's everything else, and what a formation service takes off your plate.

1
Check your name is available
Easy
Yourself: Search the Illinois business database and make sure the name follows state naming rules.
No rejected names
With a service: They check availability and naming rules before filing.
2
File your formation document ($150 state fee)
Some work
Yourself: Create an account on the Illinois filing site, fill in the form and pay. If something's wrong it gets rejected and you refile.
Saves time, fewer mistakes
With a service: You answer a short questionnaire; they prepare and submit it.
3
Name a registered agent
Ongoing hassle
Yourself: List an address in the state where someone is available every business day to accept lawsuits and state notices. If it's your home, it becomes public.
Keeps your home address private
With a service: Their address goes on the public record; they receive legal mail and forward it to you.
4
Get an EIN from the IRS
Easy
Yourself: Free on irs.gov; the online form takes about 15 minutes.
Small convenience
With a service: Some plans include it, but it's free to do yourself.
5
Write an operating agreement
Some work
Yourself: Find a template and adapt it. Banks often ask for one when you open a business account.
Ready-made document
With a service: Included in some plans.
6
Every year: file on time to keep your LLC
Ongoing hassle
Yourself: Track each deadline yourself (Annual report ($75) due before the first day of the formation anniversary month (805 ILCS 180/50-10, 35-25)). If you miss them: administrative dissolution: the SOS sends a notice, and the LLC is dissolved if it does not file the report and pay within 120 days of the notice (805 ILCS 180/35-25, 35-30).
No missed deadlines
With a service: Deadline reminders, or the filing itself, depending on the plan.

Illinois deadlines you'd be tracking

Annual report: Annual report ($75) due before the first day of the formation anniversary month (805 ILCS 180/50-10, 35-25).
First one due: Before the first day of the anniversary month of the year after formation.
If you're late: $100 if not filed before the first day of the 2nd month after the anniversary month, plus $100 for each additional year (or part of a year) of delinquency (805 ILCS 180/50-15).
If you ignore it: Administrative dissolution: the SOS sends a notice, and the LLC is dissolved if it does not file the report and pay within 120 days of the notice (805 ILCS 180/35-25, 35-30).
Getting reinstated: $200 state fee, plus any back reports, taxes and penalties

Doing it yourself makes sense if…

· You don't mind your address on the public record
· Someone is at that address every business day
· You're comfortable with government forms
· You'll set reminders for every annual deadline

A service makes sense if…

· You work from home or rent, and want your address private
· You travel or aren't reliably available during business hours
· You'd rather not learn the state's forms and rules
· You want reminders so you never miss a filing

Illinois LLC fees explained

Filing directly with the state, a Illinois LLC costs $225 in the first year and $75 a year after that. That's $50 more than the median state ($175), ranking #36 of 51 for lowest first-year cost.

Articles of organization: $150
Name reservation (optional): $25
Annual / periodic report: $75 per year. Form LLC-50.1, $75. Due before the first day of the LLC's anniversary month; first report is due in the year after formation. $100 late penalty if not filed within 60 days after the due date. Administrative dissolution if not filed within 120 days of delinquency. Expedite +$50.
Newspaper publication: not required
Expedited filing: Articles of Organization: +$100 (24-hour; $250 total online). Annual report: +$50

Articles of Organization (LLC-5.5) cost $150 with standard 10-business-day review. Online payments carry a processing fee. Series LLCs have higher fees: $400 plus $50 per series. Name reservation (LLC-1.15) is $25 for 90 days. ilsos.gov returned 403 to direct fetch, so values come from search-indexed official pages. The LLC-50.1 late-penalty form is dated 2018, but the official LLC guide agrees.

Sources

Compiled October 2026. Formation and recurring fees confirmed on official state sources.

How this calculator works

State fees come from each state's Secretary of State (or equivalent) fee schedule, compiled in October 2026. Each state page lists the sources used. Where an official page couldn't be confirmed, the page says so.

Filing fee: the standard online fee for a domestic LLC's articles of organization (or certificate of formation).
Recurring state costs: annual or biennial reports, franchise or privilege taxes and required state licenses. They're counted in the first year to be conservative.
Publication: a few states require you to publish a notice in local newspapers. Cost varies by county, so it's shown as a range.
Services: prices come from the providers' own sites (Northwest Registered Agent, ZenBusiness), checked October 2026. Ranges span real offers, for example a $39 formation with a year of registered agent included versus a $0 formation plus a $199/yr agent.

Not included: federal and state income taxes, local business licenses, professional licenses and sales tax permits, which depend on your business and city.

Frequently asked questions

Do I have to pay for an EIN?

No. An Employer Identification Number is free directly from the IRS. Services that charge for it are only filling in the form for you.

Can I be my own registered agent?

Usually yes, if you have a physical address in the state and are available during business hours. That address becomes part of the public record, which is why many owners use a service.

Should I form my LLC in Delaware or Wyoming instead?

For most small businesses, no. If you operate in your home state you'll typically have to register there as a foreign LLC anyway, paying both states' fees.
