Illinois Articles of Organization for LLCs

Use Form LLC-5.5, Articles of Organization, to create an ordinary domestic Illinois limited liability company.

Before completing the form, determine whether LLC-5.5 is actually the correct filing.

The ordinary formation process may not be appropriate if:

• The company is intended to be a series LLC.
• The business provides regulated professional services.
• Special provisions are needed in the Articles.
• The LLC has already been formed in another state or country.

An LLC already formed outside Illinois generally does not create a second domestic Illinois LLC simply to conduct business in the state. Instead, it should determine whether it must obtain authority to transact business in Illinois as a foreign LLC.

Start With the Correct Illinois LLC Filing

Different transactions require different documents.

Do not file LLC-5.5 until you have confirmed that you are actually creating a new domestic Illinois LLC.

Does Your LLC Qualify for Ordinary Online Formation?

Illinois provides an online formation process for eligible domestic LLCs.

However, the ordinary online process is not appropriate for every company.

The Secretary of State’s online instructions place limitations on companies requiring certain special provisions or purposes.

Before starting the online application, determine whether the business:

• Has an ordinary business purpose
• Needs special provisions in its Articles
• Will operate as a series LLC
• Will provide regulated professional services
• Has another feature requiring a specialized filing

If the business falls outside the standard online parameters, use the appropriate filing route rather than forcing the company into the ordinary online form.

Illinois LLC-5.5 Preparation Worksheet

Gather the information before beginning the filing.

Prepare this information first and then transfer it carefully into the actual current form or online application.

1. Choose the LLC’s Legal Name

The Articles must identify the LLC’s exact legal name.

Before filing:

1. Search the Illinois Secretary of State business database.
2. Search the distinctive words in the proposed name.
3. Review similar existing names.
4. Confirm the required LLC designator.
5. Check restricted or regulated terminology where applicable.

A clean database search does not itself guarantee acceptance.

The Secretary of State determines whether the proposed name satisfies applicable requirements when the filing is reviewed.

Use the exact accepted spelling consistently after formation.

2. Identify the Principal Office

The principal office and registered office serve different purposes.

The principal office generally identifies the company’s principal business location for the filing.

It should not automatically be confused with the Illinois registered office.

Depending on the company’s structure, the two addresses may sometimes be the same, but each must independently satisfy the requirements applicable to that field.

Do not repeat one address in both places merely because it is convenient.

3. Choose the Effective Date

Determine when the LLC should legally become effective.

Depending on the filing and applicable Illinois rules, formation may become effective upon filing or on a permitted delayed effective date.

Coordinate the effective date with important business events such as:

• Contract execution
• Asset contributions
• Bank-account opening
• Financing
• Employment
• Insurance
• Business launch
• Ownership contributions

Do not sign contracts stating that an LLC exists before confirming when the entity was actually formed, unless the agreement appropriately addresses pre-formation circumstances.

4. Appoint an Illinois Registered Agent

An Illinois LLC must maintain a registered agent and registered office meeting Illinois requirements.

The registered agent may generally be an eligible:

• Individual, or
• Entity authorized to serve in the applicable capacity

Confirm the agent’s agreement before listing the person or company.

Do not name someone who does not know that they are expected to receive official documents for the LLC.

5. Provide a Qualifying Registered Office

The registered office must satisfy Illinois requirements.

For an Illinois LLC, the registered office must be located in Illinois and correspond to the registered agent’s business office.

A P.O. Box by itself is not sufficient as the registered office.

The address should include an appropriate physical location, such as a street address or other qualifying Illinois address under the applicable Secretary of State requirements.

Check the address carefully before filing.

An incorrect registered office can interfere with receipt of legal and government notices.

Principal Office vs. Registered Office

These two fields are easy to confuse.

One address may sometimes qualify for both purposes, but that does not make the concepts interchangeable.

6. State the LLC’s Purpose

Provide the purpose required by the applicable filing.

For an ordinary business, the standard purpose framework may be sufficient.

However, additional attention is required for:

• Professional services
• Licensed activities
• Regulated industries
• Businesses requiring specialized statutory wording

Do not use generic purpose language without checking whether the profession or regulator requires something more specific.

Professional LLCs Require Additional Review

If the LLC will provide professional services, do not assume that ordinary LLC-5.5 formation is the entire process.

Depending on the profession, additional requirements may involve:

• Entity type
• Ownership eligibility
• Professional licenses
• Entity registration
• Name
• Purpose language
• Regulator approval
• Management eligibility

Illinois professional entity requirements can vary substantially by profession.

Confirm the applicable professional regulator’s requirements before filing.

7. Determine the LLC’s Duration

Review whether the LLC will have perpetual duration or another permitted duration.

Most ordinary operating businesses are structured without a predetermined termination date, but the filing should reflect the intended arrangement.

Coordinate any stated duration with:

• Operating agreement
• Investment terms
• Joint-venture arrangements
• Project duration

Do not create conflicting provisions between the Articles and internal governance documents.

8. Consider Whether Additional Provisions Are Needed

Some LLCs need provisions beyond the standard formation information.

Examples may involve unusual:

• Governance
• Management
• Authority
• Ownership structures
• Limitations or rights
• Statutory elections

Do not add complicated provisions merely because the form permits additional language.

If the LLC requires unusual governance terms, determine whether they belong in the Articles, operating agreement, or both.

Tailored legal review can be useful where public Articles will contain significant governance provisions.

9. Identify the Required Management Information

The Illinois formation filing requests management-related information.

Pay attention to exactly whom the form requires you to identify.

Do not assume that every investor or economic owner belongs in a management field.

The filing framework distinguishes between ownership and management.

Where applicable, provide the required:

• Managers
• Members having manager authority
• Business addresses

Review the actual current form before submission rather than relying solely on a generic LLC checklist.

Manager-Managed vs. Member-Managed LLCs

The management structure should also be documented in the operating agreement.

A member-managed LLC generally gives management authority to members under the applicable governance structure.

A manager-managed LLC places management authority with designated managers under the company’s governing arrangements.

The Articles, operating agreement, resolutions, and actual business practices should not contradict one another about who has authority.

10. Identify the Organizer

The organizer is the person who executes and submits the formation document in that capacity.

The organizer could potentially be:

• A future member
• A future manager
• A lawyer
• A formation service
• Another authorized person

Do not assume that signing as organizer automatically establishes ownership.

Likewise, organizer status does not by itself establish continuing authority to operate the company after formation.

Ownership and management should be documented separately in the LLC’s internal records.

Organizer vs. Owner vs. Manager

Keep these concepts separate.

Organizer: Handles the formation filing in the organizer capacity.

Member: Holds a membership interest under the applicable company arrangements.

Manager: Has management authority under the applicable governance structure.

One person can potentially occupy multiple roles, but the roles are legally distinct.

11. Sign the Articles Correctly

Review every signature field before submission.

Check:

• Organizer name
• Organizer address or identifying information required by the form
• Signature
• Date
• Any additional organizer information
• Consistency with the rest of the filing

If multiple signatures or additional information are required for the particular filing, complete them before submission.

Do not rely on an unsigned saved draft as evidence that the LLC has been formed.

How Much Does It Cost to File Illinois LLC-5.5?

The standard Secretary of State filing fee for ordinary Illinois LLC Articles of Organization is:

$150

Illinois also offers an online 24-hour service option reflected at:

$250

That amount reflects the ordinary filing fee plus the applicable expedited-service charge.

The online payment processor may add a separate processing charge.

Always review the displayed total before submitting payment.

Series LLCs and certain other specialized filings have different fees.

Online vs. Paper Filing

Eligible ordinary Illinois LLCs may be able to file online.

If filing electronically:

• Confirm that the LLC qualifies for the online process.
• Review every field before payment.
• Check the total filing and processing charges.
• Save the confirmation.
• Save the accepted Articles when available.

If filing on paper:

• Use the current LLC-5.5.
• Follow the current copy requirements.
• Follow the current payment instructions.
• Use the correct delivery address for that filing.
• Retain proof of submission.

Do not copy mailing instructions or payment rules from an unrelated Illinois corporate form.

Save the Accepted Articles

Keep the final accepted Articles of Organization with the LLC’s permanent records.

Do not retain only:

• The draft
• A screenshot
• The payment page
• An unsigned copy

Save the actual accepted filing and related confirmation.

These records may later be requested by:

• Banks
• Lenders
• Investors
• Buyers
• Accountants
• Lawyers
• Licensing authorities
• Other states

Certified Copies Are Different

A saved PDF or photocopy of the Articles may be sufficient for ordinary internal records.

But a third party may specifically request a certified copy.

A certified copy is different from an ordinary copy.

Before ordering additional documents, ask the recipient exactly what it needs.

For example:

• Ordinary copy of Articles
• Certified copy of Articles
• Certificate of good standing
• Both certified Articles and certificate of good standing

The Illinois Secretary of State provides document and certificate services, including applicable LLC document-request procedures.

Do not pay for several different records simply because someone asked for “company documents.”

Common Illinois Articles of Organization Problems

Review these issues before submission.

Wrong Transaction

Confirm that you are actually creating a new Illinois domestic LLC.

If the company already exists under another jurisdiction’s law, determine whether foreign qualification is the appropriate route instead.

Name Problem

Check:

• Availability
• Designator
• Spelling
• Restricted terminology
• Similar existing names

Special-Purpose Mismatch

Determine whether the LLC needs:

• Series formation
• Professional treatment
• Special Articles provisions
• Regulatory approval

Do this before using the ordinary online process.

Registered Agent or Address Problem

Confirm:

• Agent eligibility
• Agent agreement
• Illinois registered office
• Address accuracy
• Consistency between agent and office information

Incomplete Management Information

Review exactly what LLC-5.5 requests.

Do not substitute a passive ownership list for required management information.

Missing or Incorrect Signature

Check every organizer field and signature before submission.

Wrong Payment or Submission Instructions

Follow the instructions applicable to the selected filing channel.

Do not use instructions from an unrelated Secretary of State form.

What to Do After the Articles Are Accepted

Formation is the beginning of the LLC’s compliance process, not the end.

After acceptance, consider:

1. Save the accepted Articles.
2. Finalize the operating agreement.
3. Document initial members and ownership.
4. Document management authority.
5. Obtain an EIN if required.
6. Establish appropriate Illinois tax accounts.
7. Open business banking where appropriate.
8. Obtain required licenses and permits.
9. Arrange insurance.
10. Set up accounting records.
11. Calendar the Illinois annual report.
12. Maintain current registered-agent information.

The steps that apply depend on the company’s actual business.

Conclusion

Form LLC-5.5 is the standard Articles of Organization filing for an ordinary domestic Illinois LLC, with a standard filing fee of $150.

Before completing it, confirm that the company belongs in the ordinary formation process. Series LLCs, professional businesses, companies requiring special provisions, and LLCs already formed outside Illinois may require different treatment.

Prepare the legal name, principal office, effective date, registered agent and office, purpose, duration, management information, and organizer details before beginning the filing.

Most importantly, keep the underlying concepts separate. The organizer is not automatically the owner or manager, the principal office is not the same thing as the registered office, and filing Articles of Organization does not replace the company’s internal ownership and governance documentation.
