    How to Register Your Business in Illinois in 7 Simple Steps

    Register a business in Illinois by adhering to these seven steps for business registration:

    Step 1: Choose Your Business Structure in Illinois

    The type of your operation and expansion strategies largely influence the ideal organizational setup for your enterprise. Illinois presents a plethora of both incorporated and unincorporated business formations. We will delve into each alternative and its operational mechanics within the Prairie State.

    Remember, if you decide on a structure necessitating incorporation, registration with the Illinois Secretary of State becomes obligatory. Here are some examples:

    Sole Proprietorship

    In Illinois, the most straightforward business form to adopt is that of a Sole Proprietorship. Legally speaking, there’s no distinction between this type of business and its owner. Any financial obligations or responsibilities associated with the company fall squarely on the shoulders of its proprietor. 

    Registering a business in Illinois is hassle-free, with few legal hurdles or administrative conditions, there’s no requirement for Sole Proprietorships at a state level. However, acquiring local permits or licenses may be necessary, depending on your area.

    General Partnership

    In Prairie State, a joint business venture by two or more individuals who divide the profits and bear the losses is called a general partnership. Every partner is responsible for the company’s financial liabilities and legal duties. There’s no requirement to officially register such a partnership at the state level in Illinois. Still, submitting an ‘Assumed Name Certificate’ (also known as DBA) in your operating county might be necessary.

    Limited Partnership (LP)

    In Illinois, a restricted partnership comprises at least one general partner who oversees the enterprise and has unfettered personal liability. Also included are one or more constrained partners who invest funds but have circumscribed liability. To establish an LP in this state, it’s mandatory to submit a “Certificate of Limited Partnership” to the office of the Secretary of State in Illinois.

    Limited Liability Company (LLC)

    An LLC offers an adaptable business format that merges the liability shield characteristic of a corporation with the tax advantages and ease of a partnership. When establishing one in Illinois, it’s obligatory to submit the “Articles of Organization” to the Secretary of State in Illinois and craft an Operating Agreement defining the company’s management framework and ownership hierarchy.


    A business entity legally distinct from its proprietors, known as shareholders, and provides them with a shield of limited liability is what we call a corporation. In Illinois, there are two classifications for such entities.

    • C-corporations
    • S-corporations

    To register a business in Illinois, it’s mandatory to submit the “Articles of Incorporation” to the office of the Secretary of State in Illinois. The process for corporations involves additional formal procedures, including drafting bylaws, dispersing shares, and conducting frequent meetings with board members and shareholders.

    Determine which business framework works optimally for you, considering aspects like protection from liabilities, taxation strategies, and management needs. Seek advice from an expert specialized in legal matters or business if you require help during this decision-making process.

    Step 2: Select a Unique Business Name

    When registering a business in Illinois, selecting a unique business name is an important step. Let’s delve into the potential choices and regulations for naming in Illinois:

    Legal Entity Name

    Illinois businesses must register a unique legal entity name with the Secretary of State’s office. This name must stand out from other business names already registered within the state. It should be accompanied by an appropriate descriptor that signifies the nature of the business entity, like LLC, Corporation, or Limited Partnership.

    Potential business names can be searched on the Secretary of State’s website via their Business Entity Search tool to ensure availability.


    In Illinois, a trademark serves as a national intellectual property shield for business names or logos. It’s vital to search the USPTO database to confirm that the desired name or logo has yet to be previously registered.

    Securing a trademark offers blanket protection across the country and bars others from utilizing an identical or closely resembling name or logo for similar products or services. It should be noted that trademark registration doesn’t inherently provide carte blanche permission to use the protected name or logo under all situations.

    Doing Business As (DBA)

    Businesses in Illinois can register under a name that differs from their official entity name, known as a Doing Business As (DBA) title. This is also referred to as an Assumed Name or Fictitious Business Name.

    To legitimate your DBA designation in Illinois, it’s necessary to submit an Assumed Name Certificate at the county clerk’s office based on where your business is registered. This chosen DBA identification must be distinct and unmistakable from any other registered trade names within Illinois.

    By adhering to these naming variations and rules, you can choose a novel business identity in Illinois that complies with the state regulations while safeguarding your brand uniqueness.

    Step 3: Consider Taxes and Other Costs in Illinois

    LLCs in Illinois are mandated to fulfill several tax obligations, including but not limited to state income taxes, sales taxes, and payroll taxes. The tax burden of an LLC is contingent on several factors, such as its earnings, the nature of products or services it offers, and the count of its workforce.

    Taxation for LLCs in Illinois operates on a pass-through principle. This implies that all profit and loss generated by the LLC are directly linked to each entity member. It signifies that all members will be accountable for their proportionate share of the entity’s earnings in income tax, irrespective of whether they have received any distribution from those earnings.

    Here are some additional details about the taxes that Illinois LLCs are required to pay:

    • State Income Tax: Illinois-based LLCs are mandated to remit state income tax based on their net profits, with Illinois imposing a state income tax rate of 4.95%.
    • Sales Tax: Illinois LLCs must collect sales tax on the transactions involving goods and services conducted within the state. While the standard sales tax rate in Illinois is 6.25%, note that local governments may also introduce additional sales taxes.
    • Payroll Tax: Illinois LLCs are required to contribute to payroll taxes, which apply to the wages earned by their employees. In Illinois, the payroll tax rate stands at 7.65%, and this burden is shared between the employer and the employee.

    Registering a business in Illinois is essential to understand the tax obligations that come with it. A consultation with a tax consultant or accountant is advised to ascertain the taxes applicable to your LLC.

    Step 4: Register and Acquire Licenses and Permits in Illinois

    To register a business in Illinois, you must apply for licenses and permits. Here are some steps:

    Tax Registration: If your business intentions include the sale of goods within Illinois, it’s mandatory to register with the Department of Revenue (DOR) to levy sales tax. If your operation includes employees on its payroll, you must also sign up with the DOR for employer withholding taxes. The registration process can be completed online via MyTax Illinois’ website or by filling out a physical application Form REG-1, the Illinois Business Registration Application.

    EIN (Employer Identification Number): Should your company include staff members, or if it’s subject to separate taxation, it would be prudent to secure a federal EIN from the IRS. This also comes into play when banks require one to set up a business account or when other corporations require one for transaction processing purposes. The IRS portal facilitates EIN applications online at no charge whatsoever.

    Regulation Licenses and Permits: Your business activities might cause distinct permits and licenses relating to health, safety, environmental conformity, construction, and building or industry-specific mandates. Various state agencies typically issue these licenses. 

    For more comprehensive information, consider visiting the Registration, Licenses & Permits section on the official Illinois government site ( Further, review city or county websites where your business will operate for local licensing stipulations.

    Professional and Occupational Licenses: The Illinois Department of Financial and Professional Regulation (IDFPR) oversees certain occupations and professions. Detailed information regarding specific professions under their jurisdiction can be found on the IDFPR’s website. If your trade falls within a regulated profession’s purview, you may need to secure an occupational or professional license from the corresponding regulatory board.

    >> Register Your Business With BusinessRocket >>

    Step 5: Open a Bank Account for Your Business in Illinois

    After obtaining your EIN, initiating a commercial banking account in Illinois becomes possible.

    As state laws dictate, business bank accounts are mandatory for corporations, LLCs, and LLPs in Illinois. However, this obligation only extends to solo entrepreneurs or unregistered partnerships who can choose to mix their individual and business funds.

    Setting up a corporate account in Illinois is straightforward: simply head to your local bank branch and complete the necessary paperwork. It’s advised that you take some time to review the various offers from different banks, looking at interest rates and other benefits before making your final choice.

    Even if you’re running an unincorporated partnership or operating as a sole proprietor in Illinois, having separate financial channels for personal and business use is considered smart money management. This route now will be advantageous if you register a business in Illinois.

    Step 6: Defend Your Intellectual Property in Illinois

    In the state of Illinois, based on the type of enterprise you’re setting up, safeguarding your worthwhile intellectual property (IP) may be a requirement.

    For example, it’s common for companies to desire to shield their brand name and emblem from imitation or misuse by other parties. The necessity to defend your product blueprints or creative outputs (such as literature, artwork, or melodies) hinges on whether your firm trades in goods or delivers a service.

    Many strategies exist for defending your IP rights within Illinois, and it’s advantageous to embark on these procedures to forestall unauthorized exploitation promptly.


    In Illinois, a trademark is identified as a unique word, phrase, emblem, or design that distinguishes one product or service from others available in the market.

    To ensure its lawful safeguarding, it’s essential to register trademarks through the United States Patent and Trademark Office (USPTO). The usual duration for this registration procedure spans between four to six months. Once officially registered with the USPTO, any unauthorized usage of that trademark could be legally challenged across all states within America.

    Businesses registered in Illinois can effectively secure their brands and reputations by registering their trademarks with USPTO directly. This preemptive measure further empowers them with legal recourse against any unapproved exploitation of their registered trademarks.


    In the state of Illinois, laws about copyright safeguard original creations in areas such as literature, drama, music, artistry, and other intellectual properties. This umbrella also covers elements like software and web content, written material, films or motion pictures, soundtracks or audio recordings, and visual materials, among diverse forms of artistic expression.

    When you conceive a new work in Illinois, copyright protection is automatically conferred upon you as its originator. Holding exclusive rights over aspects such as distribution processes, reproduction techniques or adaptations, and sales related to your intellectual property means you have legal dominion over how your work is used.

    There’s an option for added security where one may officially register the copyright with the U.S. Copyright Office for enhanced legal shielding and ownership proof. Registering a business in Illinois protects against potential infringements while offering a legally enforceable method to uphold your rights if faced with any court-related proceedings.


    Creating an innovative product or machinery in Illinois necessitates obtaining a patent. The issuance of a patent endows the owner exclusive control over the item, thus preventing others from manufacturing, trading, or importing that item for a set duration.

    Navigating through the patent procedure can be complex and potentially extend to five years. Starting promptly is recommended if you possess an extraordinary invention to safeguard. Patent requests are presented to the United States Patent and Trademark Office (USPTO).

    By fortifying your intellectual assets in Illinois, you guarantee protection for your brand, goods, and creations and maintain a competitive edge for your business, facilitating its ongoing growth.

    Step 7: Configure Your Payment Infrastructure in Illinois

    Establishing a dependable and intuitive payment mechanism is critical as you gear up to serve clients promptly upon registering a business in Illinois.

    Many transaction processing solutions facilitate effortless integration with your online platform or point-of-sale (POS) system. Renowned offerings like Square, Stripe, and PayPal afford adaptability and simplicity during setup. This enables you to tailor-make your payment structure that syncs seamlessly with your commercial goals.

    These transaction facilitators support various payment modes, including credit/debit cards, ACH transfers, and digital wallets like Apple Pay and Google Pay. Opting for a respected payment processing service empowers customers by providing them with a secure transaction platform using their favored methods. This guarantees an uncomplicated exchange experience benefiting both parties involved.

    Besides configuring a payment processor, it’s crucial to establish sales tax compliance in Illinois. This involves getting an Illinois Sales and Use Tax Registration from the Illinois Department of Revenue, which enables you to collect sales tax on applicable goods and services.

    Once your payment infrastructure is set up, your Illinois-based business will be ready to serve customers and generate revenue securely and effectively. By adhering to these guidelines, you’ll be well on your way to establishing a legally compliant business in Illinois.
