Filing the Articles of Organization establishes your LLC as a separate legal entity, laying the groundwork for its operations and growth.

Create an Operating Agreement

An operating agreement is critical for your LLC. It allows customization to fit your specific needs, providing flexibility that default state rules cannot. Without it, your LLC will be subject to default state rules, which may not align with your business goals and can increase risks.

An operating agreement provides liability protection, clarity in roles, and flexibility in management structure. It serves as a contract binding all the owners to its terms, preventing disputes and reinforcing limited liability protection and legal protections.

Drafting a comprehensive LLC’s operating agreement ensures all aspects of your LLC’s operations are clearly outlined, providing a solid foundation for your business.

Obtain an EIN from the IRS

An Employer Identification Number (EIN) is essential for various business entities, including LLCs, for federal income tax purposes. Apply through the IRS for a Tax ID or Employer Identification Number. The most efficient way is online through the IRS website, where you can receive your EIN instantly.

If you prefer to apply by fax, you can expect to receive your EIN within four business days. The application requires identifying the responsible party overseeing the business. This number is used for activities like opening bank accounts, filing tax returns, and hiring employees.

Having an EIN streamlines many administrative processes, making it a crucial step in setting up your LLC.

Register for Illinois State Taxes

If your business operates or sells to customers in Illinois, you must register with the Illinois Department of Revenue (IDOR). Register electronically through MyTax Illinois, which processes applications in one to two business days. Alternatively, mailing your registration can take four to six weeks.

Upon successful registration, you will receive a Certificate of Registration or License, now issued electronically for certain tax types. Secure all necessary licenses and permits before commencing business operations to comply with legal requirements.

Comply with Ongoing Filing Requirements

Ongoing filing compliance is essential to maintain your LLC’s good standing. Failure to comply can result in fines or administrative dissolution. Corporations typically must file annual reports by a specific deadline, while LLCs have varying requirements depending on the state.

Franchise taxes, mandatory for both LLCs and corporations, must be paid annually along with franchise tax and annual fees to maintain business status. Additionally, maintaining a registered agent and office is a continuous compliance obligation for tax entities.

Keeping up with these requirements ensures your LLC remains in good standing and avoids legal or financial penalties.

Understand Self-Employment Taxes

As an LLC member:

  • You are classified as self-employed and must pay self employment taxes directly to the IRS.
  • Unlike corporations, LLC owners pay personal income tax or self-employment tax based on their share of the LLC’s earnings.
  • This tax is calculated on net profit and covers contributions for Medicare and Social Security.

The self-employment tax rate for 2024 is 15.3%, which includes contributions for Social Security and Medicare. LLC members report their share of income using Schedule K-1 on their personal tax returns.

LLC members can reduce their taxable income by deducting business expenses, such as healthcare premiums if the business is profitable, leading to potential tax savings and tax advantages. Understanding and managing self-employment taxes maximizes your LLC’s financial efficiency, especially in light of tax law and llc laws.

Consider Electing S Corp Status

Electing S Corp status can offer significant tax benefits for your LLC and s corp, including the reduction of self-employment taxes. Additionally, S Corporation owners can deduct up to 20% of Qualified Business Income, potentially lowering overall tax burdens by 20-25%. The corp election and s corp election can be a strategic move for many business owners, depending on their tax status.

Forming as an S Corporation allows income, losses, deductions, and credits to pass through to shareholders’ personal tax returns, avoiding double taxation as a pass through entity. To elect S Corporation status, file Form 2553 with the IRS, requiring signatures from all shareholders. This process is often referred to as forming s corps and can also be compared to a c corporation.

Eligibility criteria include having no more than 100 shareholders and only one class of stock to attract investors. Consult a professional for guidance to ensure it aligns with your business goals before making a decision.

Finalize Your Business Setup

Finalizing your small business setup involves several critical steps for small businesses. Choosing a suitable business bank account is essential, considering factors like low fees, convenient access, and online banking features. Establishing an effective accounting system, whether through spreadsheets, hiring an accountant, or engaging a payroll provider, helps manage your finances efficiently.

Depending on your business nature and state regulations, you may need various types of insurance, such as general liability and workers’ compensation. Additionally, using your EIN, you can open bank accounts and file tax returns promptly.
