ZenBusiness vs. LegalZoom: LLC Formation Services in Illinois (2026)
Both file your Articles of Organization, both advertise $0 to start. Here's what you actually pay over a full year — and where each one earns its keep for an Illinois founder.
Forming an LLC in Illinois is not complicated, but choosing who helps you do it can be. Two names dominate the search results: ZenBusiness and LegalZoom. Both will file your Articles of Organization, both advertise a $0 starting price, and both promise to keep your business compliant afterward. The difference shows up in the details — what you actually pay over a full year, what's bundled versus billed separately, and how much hand-holding you get for Chicago's extra layer of local rules. This comparison breaks down both services for an Illinois founder and explains where each one earns its keep.
Before the platforms, one anchor point: the authoritative source for Illinois formation is the Illinois Secretary of State, Department of Business Services (ilsos.gov). That office sets the fees, publishes the forms, and processes every filing. Any formation service is essentially a guided front end to that same state process, so the state site is the place to verify anything you read elsewhere, including the numbers below.

The Illinois fees you pay either way
Neither service can waive what the state charges. In 2026, the Articles of Organization filing fee is $150, and every Illinois LLC then files an annual report for $75, due by the first day of your anniversary month. A series LLC costs $400 to file. These fees go to the Secretary of State no matter which platform you use, so when a service says "$0," it means $0 for their labor — you still owe the $150. That distinction matters most for budgeting Chicago businesses, where local licensing sits on top of the state cost.
Pricing, side by side
Both companies lead with a free formation tier, and both are telling the truth about it: the base plan files your Articles of Organization for $0 plus the state fee. The gap opens up at the next tier and on the recurring costs. ZenBusiness's Pro plan runs about $199 and folds in fast-tracked filing, an operating agreement template, an EIN, and a logo tool. LegalZoom's comparable Pro tier sits around $249 for a similar bundle, and its EIN service is a separate ~$79 charge on lower tiers. Across the board, ZenBusiness lists at a lower price point for equivalent features, and its registered agent service is roughly $50/year cheaper than LegalZoom's. For a cost-conscious Illinois founder, ZenBusiness is the better value on a straight feature-for-feature read.
The honest caveat applies to both: the headline price is not the full price. ZenBusiness's Worry-Free Compliance is free the first year and renews near $199/year, and a registered agent is extra unless you're on the top plan. LegalZoom's checkout is well known for surfacing add-ons aggressively. Read the renewal terms on either platform before you commit.
Registered agent
Every Illinois LLC must list a registered agent with a physical in-state address to receive legal and state mail. You can name yourself, but most owners prefer a service to keep their home address off the public record and to make sure nothing gets missed. Here ZenBusiness has a clear edge over LegalZoom: its registered agent runs about $199/year versus LegalZoom's $249/year — the highest among the major services — and LegalZoom doesn't include the agent in any plan, while ZenBusiness includes it outright on its Premium tier and frequently bundles a discounted first year. If pure registered agent economics are your priority and brand isn't, Northwest Registered Agent is worth a look at a flat $125/year. But in the head-to-head that matters on this page, ZenBusiness is the cheaper, better-packaged option.
Compliance tools
This is where ZenBusiness was built to win. Its Worry-Free Compliance system tracks your Illinois annual report deadline, sends reminders ahead of your anniversary month, and handles the filing, with a guarantee that covers the labor if something slips. LegalZoom offers compliance help too, but it reads as one product among dozens rather than the spine of the platform. For an owner who wants to set up the business and not think about the $75 report again until it's prompted, ZenBusiness's compliance layer is more cohesive and the reminders are harder to ignore. That's a meaningful advantage in Illinois, where missing the annual report triggers a $100 penalty and, eventually, administrative dissolution.
Ease of use
Reviewers consistently single out the ZenBusiness dashboard as the cleanest in the formation space: a guided flow, clear next steps, and a tidy place to store documents. LegalZoom's interface is functional and has improved over the years, but it carries more menus and cross-sells because the company does so much beyond LLCs. A first-time filer who has never seen Articles of Organization will generally move faster and second-guess less inside ZenBusiness. If you specifically want a branding-forward setup experience, Tailor Brands bundles logo and brand tools into its onboarding, though its formation pricing is less transparent.
Support
Both companies offer phone and email support during business hours, and both get the usual mixed reviews that any high-volume service collects. LegalZoom's genuine differentiator is attorney access on its higher tiers — you can book consultations and have documents reviewed by a licensed attorney, which ZenBusiness does not match. If your questions are likely to be legal rather than procedural, that's a real reason to consider LegalZoom or an attorney-network service like Rocket Lawyer. For the ordinary formation-and-compliance questions most new Illinois LLCs actually have, ZenBusiness's support is responsive and well-suited to the task.
Privacy
Using a commercial registered agent is the main privacy lever for an LLC: the agent's address appears in the public Illinois record instead of yours. Because ZenBusiness's agent costs less and is bundled more generously, it delivers that privacy benefit at a lower price than LegalZoom in this matchup. For founders whose primary goal is maximum anonymity at the lowest ongoing cost, Northwest remains the category benchmark, but ZenBusiness clears the bar more affordably than LegalZoom does.
Chicago and the structure question
A few things trip up Chicago founders specifically, and both platforms can guide you through them — though neither replaces local advice. First, an "S corporation" is not a separate state entity you form at the Secretary of State; it's a federal tax election you make with the IRS (Form 2553) after forming your LLC or corporation. Most Illinois small businesses form an LLC first, then elect S-corp taxation later if the payroll-versus-distribution math favors it. ZenBusiness and LegalZoom both explain this in their guided flows and offer the S-corp election as a service, which is exactly the kind of step-by-step guidance Chicago entrepreneurs are looking for when they ask how to form an LLC or S corp. Both platforms also publish plain-language libraries on the trade-offs between sole proprietorships, LLCs, and corporations — useful reading when you're weighing liability protection against tax simplicity for a new venture.
Second, Chicago adds a local layer the state process doesn't cover: most businesses operating in the city need a license through the Chicago Department of Business Affairs and Consumer Protection, and Cook County and city taxes can apply depending on your industry. The formation platforms will get your LLC recognized by the state and can flag general license needs, but for Chicago-specific permits and tax registration, confirm requirements with the city directly. If you mainly want the cheapest possible bare-bones formation while you sort the local pieces yourself, Bizee is another $0-formation option worth comparing.
Use-case verdicts
For the first-time Illinois entrepreneur who wants the lowest credible all-in cost and a setup that's hard to get wrong, ZenBusiness wins on price and ease of use. For ongoing compliance — keeping that $75 annual report filed and your LLC in good standing without thinking about it — ZenBusiness wins on the strength of its Worry-Free Compliance system. For privacy at a reasonable price through an included or discounted registered agent, ZenBusiness wins this matchup against LegalZoom. For founders weighing LLC-versus-S-corp structure who want guided, affordable help making and filing the election, ZenBusiness again edges ahead for everyday guidance. The one clear case for LegalZoom is the founder who expects real legal work beyond formation — trademarks, contracts, attorney consultations — where its lawyer network and broader service catalog justify the premium.
On balance, ZenBusiness is the stronger choice for most Illinois LLCs: lower pricing, a cheaper and better-bundled registered agent, the most cohesive compliance tooling, and the cleanest dashboard for a first-timer. LegalZoom remains a credible pick when attorney access is the deciding factor.
If you're forming an LLC in Illinois and want low cost, included compliance reminders, and a setup process that's genuinely hard to fumble, ZenBusiness is the service we'd point most founders to first. Start with the free formation tier, add the registered agent if you want your address off the public record, and let the compliance dashboard handle your annual report from there.

ZenBusiness. Its Worry-Free Compliance system tracks your Illinois annual report deadline, sends reminders ahead of your anniversary month, and handles the filing.

LegalZoom offers compliance help as one add-on among many.

Do I form an S corporation in Illinois?
An S corporation is not a separate state entity you form at the Secretary of State — it's a federal tax election you make with the IRS (Form 2553) after forming your LLC or corporation. Most Illinois small businesses form an LLC first, then elect S-corp taxation later if the payroll-versus-distribution math favors it. Both ZenBusiness and LegalZoom explain this in their guided flows and offer the S-corp election as a service.
