Here’s the LLC Cost Guide for all US States:

Illinois Foreign LLC Formation Costs

In case you possess an LLC that’s already registered in a different state and intend to extend your business operations into Illinois, it is necessary to initiate the registration of your existing LLC as a foreign LLC in the state of Illinois.

The fee associated with the registration of a foreign LLC in Illinois amounts to $150. The procedure involves submitting an Application for Admission to Transact Business (Form LLC-45.5) to formally register the foreign LLC in the state of Illinois.

Annual Cost for LLCs in Illinois

After successfully establishing your LLC in Illinois, it’s crucial to comprehend the ongoing yearly expenditures linked with upholding compliance and operational functions. While these expenses might differ based on your individual business requisites, there are numerous standard costs to factor in when outlining your LLC’s annual budget in Illinois. 

One such cost is the Annual Report, obligating LLCs in Illinois to submit this report to the Secretary of State’s office, incurring a filing fee of $75. This report encompasses updated LLC details like address, managers, and members. Failing to meet the reporting deadline can lead to late penalties or even the dissolution of your LLC. 

Moreover, Illinois mandates a registered agent who receives vital official and legal documents on the LLC’s behalf. Opting for a registered agent for service comes with fees ranging from approximately $100 to $300 yearly. While some LLC proprietors choose to fulfill this role themselves, eliminating the expense, it requires their availability during business hours to receive legal paperwork.

Additional Costs When Starting an LLC in Illinois

Illinois LLC Name Costs

The expense for registering an Illinois business name is ($0). Selecting a name for your Limited Liability Company (LLC) comes with no financial burden. Approval of your chosen name for your Illinois LLC is included in the approval process of your Articles of Organization filing without any additional charges.

There might have been information circulating online suggesting the necessity of reserving an LLC name, but this isn’t accurate for the majority of states. Typically, forming an LLC doesn’t mandate a Name Reservation.

It’s important to verify that your chosen LLC name aligns with the naming criteria set by Illinois and isn’t already in use by another business entity.

Illinois Registered Agent Costs

When establishing your LLC in Illinois, you’re required to appoint a registered agent, either incurring a fee of $0 or $125 per year. This agent is responsible for receiving legal documents and state communications for your LLC, necessitating a valid in-state street address and availability during business hours. While you can choose to be your own registered agent or enlist someone you know, there’s no extra charge for this. 

Alternatively, you have the option to employ a registered agent service, typically priced between $100 and $300 annually. Such services offer additional business benefits and privacy safeguards. 

Opting for a registered agent service is advisable if you lack an in-state address or seek to keep your address confidential on public records, as certain companies can allow you to use their address for this purpose.

Illinois Operating Agreement Costs

There’s no cost associated with obtaining an Illinois LLC Operating Agreement, which serves as a written contract outlining the arrangements among LLC Members. This document comprehensively covers aspects of ownership, management, and profit allocation within the LLC, and it’s recommended for both Single-Member and Multi-Member LLCs to create and retain this agreement alongside their business records, providing each Member with a copy. 

While numerous websites typically charge between $50 to $200 for such Operating Agreements, acquiring one for your LLC in Illinois comes at no expense.

Illinois EIN Cost

An EIN Number, also referred to as an Employer Identification Number (EIN) or Federal Employer Identification Number (FEIN), serves various purposes, such as income tax filing, setting up an LLC bank account, and employee recruitment if needed. Despite some websites charging fees for obtaining an EIN for your LLC, it can actually be acquired for free through the Internal Revenue Service (IRS) via a quick online filing process. 

It’s important to note that the EIN Application is the sole federal requirement, while other aspects of LLC management are conducted at the state level.

Illinois LLC Taxes

The range of annual costs for Illinois LLCs varies due to the numerous types of taxes that owners are responsible for. These taxes paid by LLC owners encompass.

Federal Income Taxes.

The IRS offers various options for tax treatment of your LLC. For Single-Member LLCs, the IRS treats them as Disregarded Entities, meaning the LLC doesn’t file its own federal income tax return; instead, the owner files and pays taxes. 

The taxation method depends on LLC ownership: if an individual owns it, it’s taxed like a Sole Proprietorship; if owned by a company, it’s taxed as a branch/division. 

Multi-member LLCs are taxed as Partnerships. The LLC files a Partnership Return, issuing K-1s to owners who report their share of profits on personal returns.

Husband and Wife LLC Taxes

In some states, like community property states, husband and wife LLCs can file taxes as a Single-Member LLC (Qualified Joint Venture) or a Multi-Member LLC. Community property states allow this option; Illinois isn’t one of them, so Qualified Joint Ventures aren’t available there.

Electing Corporate Taxation

Apart from default statuses, an LLC can choose to be taxed as a Corporation: S-Corporation or C-Corporation. 

To become an S-Corp, file Form 2553; this can help profitable businesses save on self-employment taxes. For C-Corp taxation, file Form 8832; it’s less common and mostly for large employers seeking healthcare fringe benefit savings.

Illinois State Income Tax

Single-member LLCs in Illinois don’t file a state return; the owner includes LLC profits/losses in a personal state return. Multi-member LLCs might need to file a state-level Partnership return, with owners reporting the LLC’s profits/losses on personal returns. Certain industries/businesses face specific Illinois business taxes; an accountant’s help is recommended.

Personal Property Replacement Tax

Illinois LLCs pay 1.5% of net income as Personal Property Replacement Tax to the Illinois Department of Revenue.

Illinois Tax ID Number

Illinois businesses should obtain a state-level Tax ID number. This can be done online via MyTax Illinois or by contacting the Illinois Department of Revenue.

Local Income Tax

Local municipality income taxes might apply to you or your LLC; consult an accountant and check with your local authorities.

Illinois Sales Tax

If you sell to Illinois consumers, you must collect sales and use tax and get a Sales and Use Tax license (seller’s permit). Registration is available through MyTax Illinois. Variations of the term are used interchangeably.

Illinois LLC Payroll Taxes

Employing people in an Illinois LLC involves various payroll taxes: federal and state income tax withholding, Social Security and Medicare taxes, federal and state unemployment taxes, and local deductions. While you can handle it yourself, many opt for a payroll company or accountant due to the complexity and potential penalties.
