Key Facts

- Federal level: An Employer Identification Number (EIN) is a federal tax ID number that many businesses use for taxes and other business administration needs.

As of February 2026: State filing portals, state forms, and federal guidance can change, and items like beneficial ownership reporting rules have had recent updates.
People often use the phrase start an LLC to describe a state registration process
Many people search “start an LLC” or “how to get an LLC” when what they really mean is the process of forming a legal business entity under state law. In plain terms, “LLC registration” usually refers to a filing with a state office (often the Secretary of State or a similar agency), along with paying a state fee and meeting state requirements.
Because an LLC is a state-law entity, there is no single nationwide “apply for LLC” process that works the same everywhere. The name of the filing office, the filing method (online or paper), the required information, and ongoing reporting duties can vary significantly by state.
An LLC exists under state law and states set the rules for creating an LLC
The IRS explains that a limited liability company is a business structure allowed by state statute and that “each state may use different regulations.” That state-by-state design is why “how to create an LLC” can look straightforward in one state and more complex in another.
States commonly set rules about (among other things) what information must appear in the public formation document, what names are allowed, whether the LLC is member-managed or manager-managed, and what ongoing reports or fees may be required to keep the entity in good standing.
Articles of organization are the usual public filing used to form an LLC
Many states use a formation document commonly called “articles of organization” (though the name can differ). The U.S. Small Business Administration describes articles of organization as a simple document that covers the basics of the LLC and can include core business information such as the company name and address, member or management information, and registered agent information.
Registered agents are commonly used in state LLC systems
The SBA describes a registered agent as a person or company that receives official papers and legal documents on behalf of the company and notes that the registered agent must be located in the state where the company registers. States commonly tie the registered agent concept to service of process and other official notices.
Operating agreements are internal documents that govern how the LLC runs
Many LLCs use an operating agreement as an internal governance document. The SBA describes an operating agreement as a document that describes the structure of the company’s financial and functional decisions and defines how key decisions are made, as well as member duties, powers, and responsibilities.
Federal law can affect taxes and reporting after you form an LLC
Even though the formation of an LLC is a state-law event, a “business LLC” often intersects with federal agencies after it exists. Common federal touchpoints include federal tax classification rules (IRS), federal tax identification numbers (IRS EINs), and (in some contexts) federal reporting systems administered by other agencies.
The IRS classifies LLCs for federal tax purposes based on members and elections
The IRS states that an LLC can be treated for federal tax purposes as a corporation, a partnership, or as part of the owner’s tax return (a “disregarded entity”), depending on elections and the number of members. For many domestic LLCs, the default federal income tax classification is partnership treatment for multi-member LLCs and disregarded-entity treatment for single-member LLCs, unless the LLC makes an election to be treated as a corporation.
When people talk about “getting an LLC,” it can help to separate (1) state LLC formation from (2) federal tax classification, because the entity’s legal existence and its federal tax treatment are related but not the same thing.
An EIN is a federal tax ID number that many LLCs use
The IRS describes the EIN application process and offers a free online tool at Get an employer identification number. The IRS also notes that some websites charge fees even though EINs are available from the IRS at no charge.
For readers looking for “how to obtain an LLC,” it may help to know that an EIN is not the same thing as LLC formation: the IRS indicates that when someone is forming a legal entity such as an LLC, the entity is generally formed through the state before an EIN request is submitted.
Some LLCs use IRS forms to choose or document federal tax treatment
The IRS describes Form 8832 as the form an eligible entity uses to elect how it will be classified for federal tax purposes (for example, as a corporation, partnership, or disregarded entity). Whether an entity is eligible to make an election, and what the election changes, can depend on federal tax rules and the entity’s characteristics.
The IRS also describes Form SS-4 as the form used to apply for an Employer Identification Number (EIN). The IRS describes an EIN as a 9-digit number assigned to various entities for tax filing and reporting purposes.
Beneficial ownership reporting rules are a separate federal topic from state LLC registration
Beneficial ownership information reporting is not the same thing as starting or registering an LLC with a state. FinCEN maintains an official page on Beneficial Ownership Information Reporting, including its statement that (as reflected on that page) U.S.-created entities are exempt under an interim final rule published March 26, 2025, while certain foreign entities registered to do business in the U.S. may still have reporting obligations under revised rules.
Doing business in more than one state can create additional state registration layers
The SBA explains that if a company conducts business activities in more than one state, it may form in one state and then file for “foreign qualification” in other states where it is active, and that the “domestic” versus “foreign” labels are state-specific (domestic in the formation state and foreign in other states). This is one reason “register LLC” can mean more than one filing when a business operates across state lines.
States can differ on what counts as doing business in the state, and the concept is often fact-specific. As a result, general descriptions of “how to set up an LLC” often need to be read with the understanding that the rules can shift once business activity crosses state borders.
Licenses permits and tax registrations often come from multiple levels of government
Creating an LLC does not automatically mean every license or permit is in place. The SBA notes that licensing and permitting requirements can vary based on business activity, location, and government rules, and that local governments can have their own registration, licensing, or permitting requirements.
It is also common for businesses to encounter state tax registrations (such as sales tax or employer-related accounts) and local registrations, depending on the activity and where it happens. These items are typically separate from the state’s LLC formation filing itself.
Common misunderstandings that can cause delays or compliance problems
Some problems happen because people blend together several different concepts: the legal entity (the LLC), the business name (which may involve trade name or “DBA” rules that vary by state), tax accounts, and permits. Those items often involve different agencies and different paperwork.
Another common issue is assuming that “online LLC” means every state has the same portal experience. The SBA notes that some states allow online registration and some use paper filings, which can affect processing times and the way corrections are handled.
Scams and confusing third-party solicitations can also create problems. The IRS warns that third-party websites may charge fees for EINs even though the IRS provides EINs for free, and FinCEN has also posted warnings about fraudulent correspondence relating to beneficial ownership reporting.
How state offices often handle filing rejections corrections and status changes
When a state filing is rejected, state business filing offices commonly issue a notice identifying what information did not match the state’s requirements. Depending on the state, the next interaction may involve submitting corrected information, replacing the document, or filing an amendment, and the terminology and process can vary by state.
States also commonly have processes related to “good standing,” administrative dissolution, and reinstatement when required ongoing filings or fees are missed. The available review, appeal, or dispute procedures around these status changes are state-specific and can depend on the agency involved and the reason for the change.
