Many entrepreneurs researching how to start a business in the United States encounter two crucial identifiers: the Employer Identification Number (EIN) and the role of the Secretary of State. While distinct, they are often mentioned in proximity, leading to confusion about their relationship. The EIN, also known as a Federal Tax Identification Number, is issued by the Internal Revenue Service (IRS) and is essential for tax purposes, identifying business entities. The Secretary of State, on the other hand, is a state-level official or office responsible for business registration, maintaining official state records, and issuing business licenses and permits within that specific state. Understanding these roles and how they interact is fundamental to legally establishing and operating your business entity, whether it's an LLC, C-Corp, or S-Corp.

This guide clarifies the difference between an EIN and the functions of the Secretary of State, explaining why you might need both and how they fit into the broader landscape of US business formation. We’ll cover how to obtain an EIN, the typical responsibilities of a Secretary of State's office regarding business filings, and how Lovie can streamline these processes for you, ensuring compliance across all 50 states. Whether you're forming a new company or ensuring your existing one is properly registered, this information is vital for a smooth and successful business operation.
An Employer Identification Number (EIN), also referred to as a Federal Tax Identification Number (TIN), is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to business entities operating in the United States for identification purposes. Think of it as a Social Security Number for your business. It’s crucial for various federal tax purposes, including filing tax returns, opening business bank accounts, and hiring employees. The IRS uses the EIN to track business tax obligations and activities. Businesses that typically require an EIN include corporations, partnerships, LLCs with multiple members or employees, and sole proprietorships that hire employees or operate certain types of retirement plans. Even if your business structure doesn't legally mandate an EIN (like a single-member LLC with no employees in many states), obtaining one is often beneficial. It helps separate your personal finances from your business finances, which is a key advantage for liability protection in an LLC, and it's often a prerequisite for opening a business bank account or obtaining certain business licenses. For instance, if you plan to operate as an LLC in California and intend to hire staff, an EIN is mandatory. Similarly, a C-Corp or S-Corp in Delaware must obtain an EIN from the IRS shortly after its formation filing is approved by the Delaware Division of Corporations. We cover this in depth in our resource on setting up your Alaska LLC. The application process for an EIN is straightforward and can be completed online directly through the IRS website. It requires information about your business, such as its legal name, trade name (if applicable), address, responsible party’s information, and the type of business entity. There is no fee associated with obtaining an EIN from the IRS. Once approved, the EIN is issued immediately for online applications. For other methods like fax or mail, it can take several days to weeks. It’s important to note that an EIN is a federal identifier and is not issued by any state's Secretary of State office. However, the EIN is often required after you have registered your business entity with the state.
The Secretary of State (SOS) is a state government official, typically elected, whose office serves as the primary custodian of official state records and plays a pivotal role in the formation and ongoing compliance of business entities within their respective state. When you decide to form an LLC, C-Corp, S-Corp, or nonprofit in a specific state, such as Texas, New York, or Florida, you will file your formation documents (like Articles of Incorporation or Articles of Organization) with the Secretary of State's office (or a similar state agency responsible for business filings, sometimes called the Division of Corporations, Department of State, or Corporations Division). This filing process officially registers your business entity with the state, granting it legal status to operate within that jurisdiction. The SOS office is responsible for reviewing and approving these documents, ensuring they meet state requirements. For example, to form an LLC in Wyoming, you would submit your Articles of Organization to the Wyoming Secretary of State, pay the required filing fee (currently around $100), and upon approval, your LLC legally exists in Wyoming. The Secretary of State also maintains records of all registered businesses, including annual reports, amendments to formation documents, and business name registrations (DBAs or 'Doing Business As' names). Key responsibilities of the Secretary of State's office concerning businesses include:
Business Registration: Accepting and processing formation documents for LLCs, corporations, and nonprofits. Name Availability: Checking if a proposed business name is available for use in the state. Check out our guide on starting a business in Arizona for step-by-step instructions. Annual Reports/Fees: Requiring businesses to file annual or biennial reports and pay associated fees to maintain active status. For instance, a business in Illinois must file an annual report with the Illinois Secretary of State and pay a fee. Registered Agent Designation: Ensuring businesses have a designated registered agent located within the state to receive official legal and tax documents. * Public Record Keeping: Making business information accessible to the public. While the Secretary of State handles the state-level registration and compliance, they do not issue federal tax identification numbers. That is exclusively the domain of the IRS.
The core distinction lies in their origin and purpose. An EIN is a federal identifier issued by the IRS for tax administration, while the Secretary of State is a state-level entity responsible for the legal formation and registration of businesses within a specific state. You obtain an EIN from the IRS after or around the time you register your business with the state. The state filing with the Secretary of State establishes your business as a legal entity, while the EIN allows that entity to function in the financial and tax system.
Consider this scenario: You want to start an LLC in Nevada. First, you must file your Articles of Organization with the Nevada Secretary of State. This process costs a filing fee (around $75) and officially creates your Nevada LLC. Once your LLC is approved by the state, you can then apply for an EIN from the IRS. This EIN will be used for federal tax purposes, opening a business bank account in Nevada under your LLC's name, and potentially for state tax purposes if Nevada had a state income tax for businesses (it does not for LLCs, but many other states do). The Nevada Secretary of State has no involvement in issuing or managing your EIN.
Similarly, if you form a C-Corporation in Delaware, a popular choice for startups, you file your Certificate of Incorporation with the Delaware Division of Corporations (often part of the Department of State). After receiving confirmation from Delaware, you would then proceed to the IRS to obtain your EIN. The Delaware filing fee is typically around $90. The state ensures your corporation is legally constituted, while the IRS EIN allows it to operate as a distinct taxpayer. The Secretary of State's office in Delaware, like in any other state, does not provide an EIN; that's solely an IRS function. This federal-state division of responsibility is consistent across all 50 states, although specific filing fees, report requirements, and processing times vary.
Establishing a legal business entity requires compliance at both the state and federal levels. State registration, managed by the Secretary of State's office, is the foundational step that grants your business legal personhood. This means your LLC or corporation can enter into contracts, own property, and sue or be sued in its own name, distinct from its owners. Without state registration, your business is not legally recognized, making it impossible to operate legitimately, secure funding, or protect personal assets from business liabilities. For example, forming an S-Corp in California requires filing Articles of Incorporation with the California Secretary of State and paying a $100 filing fee. This action legally creates your corporation within California.
The EIN, issued by the IRS, is the next critical step for operational and financial integration. It's your business's identifier for federal tax purposes. You will need an EIN to file federal income tax returns, pay federal taxes (like employment taxes if you have employees), and comply with IRS regulations. Beyond taxes, most banks require an EIN to open a business checking or savings account, even for single-member LLCs in many cases. This is vital for maintaining the separation between personal and business finances, a cornerstone of liability protection. Imagine trying to open a business account for your new LLC in Ohio without an EIN; the bank will likely deny your request. The Ohio Secretary of State approves your LLC's existence, but the IRS EIN allows it to participate in the financial system.
Furthermore, many states require an EIN for state tax registration, even if they don't have a state income tax for certain business types. For instance, if your business hires employees in any state, you'll need an EIN to report state payroll taxes. Even for businesses that don't directly pay state income tax, such as an LLC in Texas, having an EIN is essential for opening bank accounts and often for obtaining necessary state or local business licenses and permits. The Texas Secretary of State registers your LLC, but the IRS EIN is the key that unlocks essential financial and operational capabilities, ensuring your business can thrive legally and financially across the United States.
Applying for an EIN is a straightforward process managed entirely by the Internal Revenue Service (IRS). The most efficient method is through the IRS's online application portal. This method is available to individuals with a valid Taxpayer Identification Number (SSN, ITIN, or existing EIN) and a confirmed address in the United States or U.S. territories. To begin, visit the official IRS website and navigate to the EIN application page. You will need to provide accurate information about your business, including its legal name, trade name (if any), mailing address, physical address, responsible party’s name, title, SSN, and the type of entity (e.g., LLC, Corporation, Partnership).
The application typically takes about 5-10 minutes to complete. Once you submit the application, if all information is accurate and verifiable, the IRS will issue your EIN immediately. You will receive a confirmation letter (CP 575) from the IRS containing your EIN. It is crucial to save this document securely, as you will need it for various business purposes. If you are unable to apply online, you can also apply by fax or mail, though these methods take significantly longer – typically several business days to a few weeks for processing.
For businesses being formed or already registered in specific states, the process remains the same: apply directly with the IRS.
