Illinois LLC Quick Facts
- Filing fee: $150 to file Articles of Organization (Form LLC-5.5) with the Illinois Secretary of State. Online filings clear in roughly 5 to 10 business days. Mail filings run 7 to 14 business days plus mail time. Paying an extra $100 for expedited service brings that down to about 24 hours [1].
- Annual report: $75 a year, due before the first day of the month the LLC was originally formed. The state opens the filing window 45 days ahead of that deadline, and a $100 late penalty applies the day after it passes [2].
- Registered agent: requires a continuous physical street address in Illinois. PO boxes, mail drops and virtual-only addresses don't satisfy the requirement, and losing one is grounds for the state to administratively dissolve the LLC [3].
- State taxes: Illinois LLCs taxed as partnerships owe a 1.5% Personal Property Replacement Tax on net Illinois income, on top of the regular pass-through personal income tax owners already pay [4].
ZenBusiness Top 9 LLC Services in Illinois (July 2026)
1 - ZenBusiness (Best Overall)
Pros and Cons
- Costs nothing beyond the Illinois filing fee to start
- Velo assistant catches missing steps without being asked
- One dashboard tracks formation, agent status and licenses
- Filing took about 10 minutes from start to finish
- Registered agent service is not included on the two cheaper plans
Who is it for?
Who is it for?
- Illinois founders who want a low-cost formation plan with a working dashboard behind it.
- First-time owners who'd rather software flag a missing step than track it themselves.
Who is it not for?
- Owners who want registered agent service included from the entry-level plan.
The Verdict
ZenBusiness earned the top spot because Velo caught a real gap in our account before we noticed it ourselves. No single price point decided it.
ZenBusiness's Velo assistant flagged our missing EIN the moment we logged back in. It pointed us straight to the compliance tab.
That tab tracks formation status, registered agent status and license checks in one place. Nothing got buried in a separate tool. Filing took about 10 minutes. The portal never asked us to hunt for a missing field.
ZenBusiness LLC formation packages:
- Starter ($0 + $150 state fee): Covers the Articles of Organization filing with standard 7-10 business day processing and dashboard access. Registered agent service is not included.
- Pro ($199 + $150 state fee): Adds 1-business-day internal processing, an EIN, an operating agreement template and a year of Worry-Free Compliance monitoring. Registered agent is still not bundled here.
- Premium ($399 + $150 state fee): Adds registered agent service, 24/7 compliance monitoring and unlimited amendment filings on top of everything in Pro.
- Registered agent renewal ($199/yr): Sold separately on Starter and Pro. It's included only inside Premium.
2 - Northwest Registered Agent (Best Premium)
Pros and Cons
- Keeps your street address off Illinois's public LLC filing
- Named Corporate Guide instead of a rotating support queue
- Formation documents upload automatically once approved
- Entry price runs higher than the cheapest options on this page
Who is it for?
Who is it for?
- Business owners who want their street address kept off Illinois's public filing record.
- Founders who'd rather work with a named contact than a support queue.
Who is it not for?
- Owners chasing the lowest possible first-year total above everything else.
The Verdict
Northwest is the pick when privacy and a real point of contact matter more than shaving a few dollars off the entry price.
A welcome email from a named Corporate Guide landed within a day of our Illinois order. It read like something an actual person wrote, warmer than a form letter.
Northwest owns its own registered agent offices. It doesn't route mail through an outside firm. Once the state approved our filing, the formation document and a starter operating agreement showed up automatically. We never had to ask.
Northwest keeps your street address off the public filing. That one decision shapes most of what the account offers.
Northwest Registered Agent LLC formation packages:
- Base formation ($39 + $150 state fee): Includes the Articles of Organization filing plus a full first year of Illinois registered agent service.
- Registered agent renewal ($125/yr): Applies after the included first year ends.
- Business Identity bundle (included): A domain, hosted website with SSL, up to 10 business email addresses, a business phone line and mail scanning stay bundled free for as long as registered agent service is active.
3 - Tailor Brands (Best For New Brands)
Pros and Cons
- Formation and branding move through one signup flow
- Navi assistant surfaces financial tracking on first login
- Dashboard keeps branding, finance and compliance in separate tabs
- Registered agent service isn't free for a first year
Who is it for?
Who is it for?
- New founders who want branding and LLC filing handled through one signup.
- Brand-focused entrepreneurs who'd rather launch with a finished look right away.
Who is it not for?
- Owners who only want a bare-bones filing with nothing else attached.
The Verdict
Branding lands the same day as the filing here, which is the whole reason to pick Tailor Brands over a plain formation-only service.
Tailor Brands tracked our filing status in the dashboard the whole way through, then dropped the approved formation documents into the same account as soon as the state signed off.
The dashboard splits branding, finance and compliance into separate tabs. Finding the annual filing tracker never meant scrolling past marketing tiles.
Navi, the in-account assistant, surfaced our financial tracking on first login. We hadn't asked where to find it yet. The registered agent price stays flat from day one. There's no renewal jump to plan around later.
Tailor Brands LLC formation packages:
- Lite ($0 + $150 state fee): Covers the LLC filing itself with standard processing and no branding extras.
- Essential ($199/yr + $150 state fee): Adds expedited filing, a logo maker, a website and annual compliance filing.
- Elite ($249/yr + $150 state fee): Adds a free first-year domain, a full website builder, digital business cards and a social post maker on top of Essential.
- Registered agent (included, $199/yr renewal): Bundled into Essential and Elite. It bills at the same $199/yr rate from day one on Lite.
4 - LLC Attorney (Best Essentials)
Pros and Cons
- A real reviewer checks the Articles of Organization before filing
- Registered agent service included for year one on every option
- Support answered follow-up questions in plain language
- Long-term legal advisory features are thinner than full-service competitors
Who is it for?
Who is it for?
- Illinois founders who want a licensed reviewer checking the paperwork before it's filed.
- Owners who want registered agent service included for year one without a separate purchase.
Who is it not for?
- Founders who need an ongoing legal-advisory relationship built into the base filing.
The Verdict
A real reviewer on the cheapest option here is a rare combination, and it's why LLC Attorney earns a spot without any extras attached.
LLC Attorney asked for every Illinois detail up front. A live reviewer checked our filing before it went to the state.
Registered agent service is free for year one on every option here. Most others charge extra for it. Support answered in plain words instead of sending us to a help article, including a question about choosing LLC status over an S-Corp election.
LLC Attorney LLC formation packages:
- Starter ($49 + $150 state fee): Covers the Articles of Organization filing, organizational minutes and a bank account resolution.
- Professional ($199 + $150 state fee): Adds an EIN, a Certificate of Good Standing and one free amendment within the first 90 days.
- International+ ($399 + $150 state fee): Adds a foreign entity filing or subsidiary setup plus an apostille and Certificate of Incumbency.
- Starter Compliance ($14.99/mo): An ongoing subscription covering annual filing handling and mail scans, layered on top of the included year-one registered agent service rather than replacing it.
5 - LegalZoom (Best Legal Advisor)
Pros and Cons
- Attorney network extends past the initial LLC filing
- Document center offers e-signature and a template library
- Compliance quiz flags license needs early
- Costs more overall than several competitors on this page
Who is it for?
Who is it for?
- Business owners who want access to a broader legal network beyond a single filing.
- Founders comfortable paying more for a long-established brand and its document library.
Who is it not for?
- Cost-conscious owners who don't need legal services beyond the initial filing.
The Verdict
The independent attorney network is the real differentiator here. Several competitors handle the filing itself just as well for less.
LegalZoom's dashboard lists a network of independent attorneys, available by subscription. Most competitors here skip that entirely.
The document center handles e-signature on its own. It also pulls from a library of attorney-drafted templates that stay useful long after the initial filing. A compliance quiz inside the dashboard flags license needs early. That beats finding out at renewal time.
LegalZoom LLC formation packages:
- Basic ($0 + $150 state fee): Covers the Articles of Organization filing only.
- Pro ($249 + $150 state fee): Adds an operating agreement, an EIN, a Wix-powered website and a phone consultation with a business specialist.
- Elite ($299 + $150 state fee): Adds LZ Books bookkeeping, invoicing and mileage tracking on top of Pro.
- Registered agent renewal ($249/yr): Includes a compliance calendar, email alerts and identity-theft protection.
6 - Inc Authority
Pros and Cons
- Base LLC filing costs nothing beyond the state fee
- Registered agent is free for the first year
- Post-payment logo builder opens right after formation
- Checkout runs through several timed upsell screens before payment
Who is it for?
Who is it for?
- Founders comfortable declining a string of timed upsell offers at checkout.
- Owners who want a free first-year registered agent without shopping around.
Who is it not for?
- Anyone who dislikes clicking through a multi-screen upsell sequence before paying.
The Verdict
Inc Authority delivers on its free formation and free registered agent year, once you click past a few upsell screens.
Inc Authority's checkout walks through several timed upsell screens before the final payment page. Knowing that up front keeps it from feeling like a switch.
The account opened straight into a logo builder as soon as formation was done. That was a pleasant surprise at such a low entry cost.
The free first-year registered agent was included as advertised. A second free perk turned out to be a pick-one choice at checkout rather than an automatic bonus.
Inc Authority LLC formation packages:
- Free LLC ($0 + $150 state fee): Includes the LLC filing and a free first-year registered agent. Checkout also offers one free perk of your choice: an EIN or 24-hour expedited processing, though only one applies.
- Starter Business Bundle (add-on, priced at checkout): Adds an operating agreement and a deluxe record book.
- Registered agent renewal ($249/yr): Applies after the included first year ends.
- Features
7 - Harbor Compliance
Pros and Cons
- Project-status tracker shows exactly where the filing stands
- Entity Manager scans legal mail same-day once agent service is active
- Item-by-item pricing means you only pay for what you pick
- No onboarding call or guided walkthrough for new customers
Who is it for?
Who is it for?
- Founders who'd rather build their own filing item by item than pick a fixed option.
- Owners who want same-day legal mail scanning tied to an account dashboard.
Who is it not for?
- First-time filers who want a guided walkthrough instead of a self-serve portal.
The Verdict
No sales call and nothing folded in for free means the portal itself has to do the selling, and Entity Manager mostly pulls that off.
Harbor Compliance skips the sales call entirely. The client portal collects whatever's still needed, and a project-status tracker shows exactly where the filing sits.
Entity Manager scans legal mail the same day it arrives, once registered agent service is active. That tracking syncs directly with the account instead of living in a spreadsheet.
Nobody walks new customers through the dashboard step by step. The flow leans on its own tutorials and help content instead.
Harbor Compliance LLC formation packages:
- Formation package ($99 + $150 state fee): Covers the Articles of Organization filing only. Registered agent is priced and billed separately below.
- Registered agent (new customers, $99/yr): Billed as its own line item alongside formation, renewing at $149/yr for every customer after the first term.
- Managed annual report service ($175/yr + $75 state fee): Tracks the due date and handles the filing instead of leaving it to a reminder alone.
8 - Bizee
Pros and Cons
- Costs nothing beyond the Illinois filing fee to start
- Order review shows the full total before payment
- Filings tab separates state and federal paperwork clearly
- Support is only available on weekdays
- Standard filing speed runs slower than several competitors here
Who is it for?
Who is it for?
- Founders on a tight budget who want a free filing and a free first-year agent.
- Owners who like separating state and federal filings inside one dashboard tab.
Who is it not for?
- Owners who need weekend or after-hours support access.
The Verdict
Bizee is a solid budget pick as long as weekday-only support and standard filing speed both fit your timeline.
Bizee's order review screen laid out the full total before payment, down to the exact state fee. There was nothing left to discover afterward.
The dashboard's filings tab keeps state and federal paperwork on separate views. An amendment option sits in plain view right next to the annual report filer.
Support only runs on weekdays, so a weekend question waits until the next business day. A first-year registered agent came included, so our only cost at checkout was Illinois's own filing fee.
Bizee LLC formation packages:
- Basic ($0 + $150 state fee): Covers the LLC filing, a free first-year registered agent and lifetime compliance alerts.
- Standard ($199 + $150 state fee): Adds an EIN, an operating agreement, a free domain and business email, a free first-year business phone number and unlimited phone and email support.
- Premium ($299 + $150 state fee): Adds expedited state filing and S-Corp election filing on top of Standard.
- Registered agent renewal ($119/yr): Applies after the included first year ends.
9 - MyCompanyWorks
Pros and Cons
- Same-business-day filing on every option
- Clear three-option lineup instead of a long extras menu
- Responsive phone and email support during business hours
- Refund policy excludes fees once documents have shipped
- Phone support is limited to weekday business hours
Who is it for?
Who is it for?
- Owners who prefer a short, clear lineup over a long menu of extras.
- Founders comfortable with weekday-only phone support.
Who is it not for?
- Owners who want a refund option that still applies after documents have shipped.
The Verdict
MyCompanyWorks is a reasonable fit for founders who want a simple lineup and same-day filing without extra add-ons to weigh at checkout.
MyCompanyWorks keeps its lineup simple. Three clear options, each one building on the last, with no maze of screens at checkout.
Every option processes on the same business day it's submitted, per the provider's published terms. Phone and email support run during standard weekday business hours.
The refund policy is stricter than most. It excludes fees once documents have already shipped, so cancel before that point if you change your mind.
MyCompanyWorks LLC formation packages:
- Basic ($79 + $150 state fee): Covers the Articles of Organization filing and a tax consultation.
- Entrepreneur ($199 + $150 state fee): Adds a lifetime forms and tax guide, an EIN and a year of registered agent service.
- Complete ($279 + $150 state fee): Adds priority support on top of Entrepreneur.
- Registered agent renewal ($119/yr): Applies outside a bundling tier.
How We Picked and Tested the Best LLC Services in Illinois
We formed an LLC with each of these nine services and worked through every checkout and dashboard ourselves before scoring anything. Our full testing methodology explains exactly how we weight each category.
We scored all nine services across six categories: support, price, features, turnaround, ease of use and user ratings. Then we added a seventh check specific to how well each service fits an Illinois filing.
1. Support
A support score comes down to what happens when a question can't wait for a help-center article rather than what the sales page promises.
ZenBusiness and Northwest tie for the top score here. ZenBusiness's Velo assistant flags account gaps the moment you log back in. Northwest assigns a named Corporate Guide who follows up personally rather than routing you through a ticket queue.
2. Price
The cheapest plan only earns a high price score if it still does something useful once the filing is done. Several $0 tiers on this page drop to a bare confirmation email with no ongoing dashboard, the exact gap that keeps a free plan from scoring well.
No provider on this page beats ZenBusiness here. Its Starter plan costs nothing beyond the Illinois filing fee and still ships a working compliance dashboard instead of a stripped-down form.
3. Features
The widest feature sets on this page belong to the two services that build well past a one-time filing. ZenBusiness's dashboard tracks formation, registered agent status and licenses in one view, while Tailor Brands pairs formation with branding, a website builder and financial tracking.
ZenBusiness leads this category outright. Tailor Brands and Northwest follow right behind it, both stacking account tools onto the base filing rather than treating it as a single transaction.
4. Turnaround
Internal processing speed varies more across these nine services than Illinois's own approval time does. LegalZoom's registered agent renewal terms took longer to parse than the filing itself, while Bizee's standard tier still runs a multi-week queue before it even reaches the state.
ZenBusiness posted the fastest internal turnaround of the group in our test, with Northwest close behind.
5. Ease of Use
The easiest accounts to use are the ones that keep every task inside a single login rather than sending you elsewhere for compliance or documents.
ZenBusiness leads this category with the only 5.0 ease-of-use score among these nine, and Tailor Brands follows closely by keeping branding, finance and compliance in one dashboard.
6. User Ratings
Third-party review scores line up closely with what our own testing found across these nine services. ZenBusiness and Northwest, the same pair that led our support score, also carry the strongest independent review profiles among the group.
ZenBusiness and Northwest tie for the highest user-ratings score on this page, with Tailor Brands just a step behind.
7. Illinois Fit
Illinois's physical-address rule for registered agents and its yearly anniversary-month report reward two different strengths, so the best statewide fit isn't a single winner.
Northwest fits the address rule most cleanly, since it staffs its own registered agent offices rather than farming mail out to a third party. ZenBusiness's compliance dashboard, on the other hand, lines up well with Illinois's anniversary-month deadline.

Steps To Form An LLC In Illinois
- Choose a business name. Confirm it's available through the Secretary of State's business entity search and includes an LLC designator before filing.
- Appoint a registered agent. Illinois requires a continuous physical street address in the state. See our best Illinois registered agent services if you'd rather not use your own address.
- File the Articles of Organization. Submit Form LLC-5.5 with the $150 filing fee online or by mail, to the Illinois Secretary of State.
- Draft an LLC Operating Agreement. Illinois doesn't require filing one with the state, but it sets the rules for ownership, management and profit distribution among members.
- Get an Employer Identification Number. Apply directly through the IRS online for free after the state approves the LLC.
- Track the annual report deadline. Mark the $75 report due before the first day of your LLC's anniversary month so it doesn't lapse into a late penalty.

FAQs
How Long Does It Take To Form An LLC In Illinois?

How Much Does It Cost To Start An LLC In Illinois?
The state charges $150 to file Articles of Organization. Formation services add their own service fee on top, ranging from $0 to a few hundred dollars depending on the package.
Do I Need A Registered Agent For My Illinois LLC?

No. Filing the Articles of Organization online is a straightforward process, and most of the services on this page can walk you through it in under 15 minutes.
How Is An LLC Taxed In Illinois?

When Is My Illinois LLC Annual Report Due?
Before the first day of the month your LLC was originally formed, every year. Illinois opens the filing window 45 days early and adds a $100 penalty the day after the deadline passes.
Our Verdict
ZenBusiness is our top pick for most Illinois LLC owners, based on how the account handled our filing without us having to chase down a single missing step.
Northwest is the stronger choice when privacy and a named point of contact outweigh price. Bizee and Inc Authority fit owners who want the smallest possible bill in year one, as long as renewal pricing gets watched closely.
Pick ZenBusiness for the most balanced filing experience in Illinois. Pick Northwest, Bizee or Inc Authority only when one of those specific trade-offs matters more to you than an all-around fit.

Oh sure, because that’s exactly how things work. NOT! What a joke.
Actually, if you look at the recent data, you’ll see a different trend. I suggest checking more reliable sources.
I can’t belive you think that’s true. This is totally misleading and off base. Do better next time!
Wow, great article! Really enjoyed the insights. Keep up the good work!
It’s quite informative but some points were a bit unclear. Maybe a follow-up with more details?
