To learn how to start an LLC step by step, choose the state and business structure that fit your plans. Then check the name, identify a registered agent, and file the state’s formation documents. After the state creates the LLC, you can address tax registrations, banking, licenses, and recurring obligations. The U.S. Small Business Administration advises choosing a business structure before registration because that choice affects taxes, paperwork, fundraising, and personal liability. Review the SBA’s business-structure guidance as you consider the choice.

Formation is more than submitting a state form. Your state sets the registration process, while your ownership, management plans, and location shape which steps follow. It also helps to separate the state-law entity from its federal tax classification. The IRS explains that an LLC’s federal treatment depends on factors such as its number of members and any elections it makes. The LLC label alone does not settle every tax question.
For a broader look at entity selection and tax planning, see OGC Tax Pros’ Business Formation and Tax Entity Strategy Guide. The sections below focus on turning that decision into a planned LLC, from name search and state filing to tax setup and ongoing compliance. OGC Tax Pros supports business formation and entity evaluation for owners who want help considering those decisions.
How to start an LLC step by step, from the name onward
Before you file, decide where the LLC will be formed and identify a name that can be used there. These choices are connected: your business location can affect taxes and legal requirements, while registration depends on the business structure and location. The SBA recommends checking that a business name is not already in use and confirming the applicable rules with state and local authorities.
Choose the state, then search its business records
For many small businesses, the practical starting point is the state where the business will operate. Forming elsewhere does not automatically remove obligations where you actually work, so compare the relevant locations before filing. Check the chosen state’s Secretary of State or business registry for an LLC name search. The search helps identify names that may conflict with records in that state, but availability rules and reservation options vary. Confirm current instructions with the state before relying on a result.
A state entity-name search answers a narrower question than whether a brand is clear for every use. The LLC’s legal name is the name recorded for the entity. A DBA, or trade name, is a name a business may use publicly under applicable state or local rules; it does not by itself create the LLC. A domain name is a web address, and availability there does not establish state-name or trademark rights. State acceptance of an entity name should not be treated as trademark clearance. Check relevant trademark records and get qualified advice if the brand matters to your launch.
Identify a registered agent before filing
A registered agent is the designated contact for receiving official notices and legal papers for the LLC. Decide who will fill that role before completing formation paperwork, and make sure the person or service can reliably receive documents and pass them on promptly. Requirements differ by state, including rules about who may serve and what address is acceptable. Do not assume that a home address, mailing address, or out-of-state agent will qualify. Review the current formation instructions on the official state website.
These early checks can prevent avoidable changes later. The SBA explains that business location and name checks are part of planning a business, and that registration requirements vary by state. Once the name and agent details are settled, prepare the state’s formation filing with accurate information.
File the formation documents with your state
Once you have settled on the LLC name and the state’s required representative, submit the state’s formation filing. The document is often called Articles of Organization, though the name and process vary. The SBA notes that registration depends on business structure and location, and requirements vary by state. Start with the official business-registration agency for the state where you are forming the LLC, rather than relying on a third-party summary: SBA guidance on registering a business.
Before opening the filing form, gather the details the state may request. These commonly include the LLC’s proposed legal name, address, registered agent information, management structure, and filer contact details. The form may ask for more. Treat this as a preparation list, not a universal checklist. Review the current form and instructions from your state agency, and provide information exactly as requested.
Submit the filing through the state’s official online service or by another method the agency permits. Check its instructions for signatures, attachments, payment steps, and how it communicates a decision. States do not all use identical forms or process filings on the same schedule, so avoid making plans around an assumed approval date. If information is incomplete or inconsistent, the agency may need you to correct or resubmit it.
For example, Florida directs filers to its Division of Corporations, Sunbiz, for current Florida LLC Articles of Organization filing instructions. That is a Florida-specific route, not a template for every state. If you are forming elsewhere, use that state’s own agency and current guidance.
After submitting, save the confirmation, payment receipt, and any filing reference number. When the state accepts the filing, retain the approved formation record with the LLC’s core business documents. You may need it for later setup tasks, but the filing is only one part of getting the business ready to operate.
Put the LLC’s internal rules in writing
After the state filing establishes the LLC, turn to how the business will operate. An operating agreement is an internal governance document. It records the owners’ shared expectations and gives the company a reference point when decisions or disagreements arise. It is separate from the formation document filed with the state. Requirements and default rules vary by state, so check the rules where the LLC is formed rather than assuming every state mandates an agreement.
For a multi-member LLC, use the agreement to clarify practical matters before money or responsibilities become contentious. Depending on the business, it can describe:
- Each member’s ownership interest and initial or future contributions.
- Who manages daily operations, which decisions require a vote, and how voting power is determined.
- How the LLC will keep company records and document important decisions.
- How profits may be allocated and when distributions may be made, subject to applicable law and the company’s financial needs.
- What happens if a member wants to leave, becomes unable to participate, or the owners decide to change the business.
A single-member LLC can also benefit from written operating rules that describe how the owner manages the company and keeps its affairs organized. These documents address separate questions from state formation and federal tax classification:
| Question | What it covers | Where to check |
|---|---|---|
| State-law formation | Creates the LLC as a legal entity under state rules. | The state’s business registration agency. |
| Operating agreement | Sets internal expectations for ownership, management, decisions, and records. | The agreement and applicable state rules. |
| Federal tax classification | Determines federal tax reporting based on member count and any elections. | IRS guidance and advice for your circumstances. |
The IRS generally treats a single-member LLC as disregarded for federal income tax unless it elects corporate treatment. A domestic LLC with at least two members is generally treated as a partnership unless it elects otherwise. These are default classifications, not individualized tax advice. Employment and excise-tax duties can add rules. See the IRS guidance on LLC federal tax classification. For legal language suited to the owners and state, consult a qualified attorney. OGC Tax Pros’ business formation and tax entity strategy guide explains why legal structure and tax planning should be considered together.
Get tax registrations, an EIN when needed, and a business bank account
Once the state has legally formed your LLC, handle its federal identification and any state or local tax registrations. These are separate steps. An EIN is a federal tax identification number issued by the IRS, while state tax accounts or permits are handled by state or local agencies. What you need depends on how the business operates and where it is located.
Do not assume that creating an LLC determines its federal income tax classification. The LLC is created under state law, but the IRS classification depends on the number of members and any elections made. In general, a single-member LLC is treated as a disregarded entity for federal income tax unless it elects corporate treatment. A domestic LLC with two or more members is generally classified as a partnership unless it elects to be treated as a corporation. These are default classifications, not personalized tax recommendations. Employment and excise-tax obligations can also affect filing requirements. Review the IRS explanation of LLC tax treatment and discuss your circumstances with a qualified tax professional.
An EIN is generally required when an LLC has employees or certain excise-tax filing obligations. Some single-member LLCs without employees or excise-tax liability may not need a separate EIN for federal tax purposes. Though a bank or another requirement may still call for one. Check the IRS rules for your circumstances. The IRS instructs LLCs to complete formation through the state before applying for an EIN. You can apply directly through the IRS online application at no charge; if approved, the IRS issues the number online. Use the official IRS EIN application and guidance, and avoid paying a third party simply to submit the application.
After formation, consider opening a business bank account for business income and expenses. Keep those transactions separate from personal funds. This makes records easier to organize and helps you see the business’s activity clearly. Banks set their own eligibility and documentation rules, so confirm what yours needs before applying. It may request formation records or an EIN, depending on the bank and your circumstances. The SBA guide to opening a business bank account explains why separation matters and what to prepare.
State tax registrations are a separate check. Depending on your activities and location, you may need state tax accounts, such as employer withholding or sales-related registrations. Requirements vary, so confirm them with the appropriate agency. For entity and tax background, see OGC Tax Pros’ overview of LLC tax classification options. General information cannot determine the right treatment for your business.
Check licenses, taxes, and recurring state obligations
State approval establishes the LLC, but does not clear every requirement for operating the business. Licensing and permit rules can depend on industry, state, and location. A storefront may face different requirements from a home-based or online business. Local rules can still apply to a home business. The U.S. Small Business Administration explains that location affects taxes, zoning, and regulations (SBA guidance on location, taxes, and tax IDs).
Before opening, check with state and local agencies for permits, professional or industry licenses, and zoning approvals that fit your activities and business address. Do not assume that registering an LLC or working from home exempts you from local rules. Requirements may also change if you add a service, hire employees, or move.
Taxes need their own review. The LLC’s state-law formation and federal tax classification are separate questions. Federal treatment can depend on member count and elections. State and local tax registrations or payment obligations can depend on where and how the company operates. Confirm the requirements with the responsible agencies or a qualified tax professional rather than relying on the LLC label alone.
After formation, check the state registry’s instructions for recurring reports, renewals, fees, and deadlines. These obligations vary by state and may differ if you operate in more than one jurisdiction. Georgia and Washington publish separate annual-report requirements, a reminder that one state’s schedule is not a national rule. Use your state’s official pages as the source of truth. Add reminders to your business calendar, keep agency notices, and update your contact information.
OGC Tax Pros offers business formation, tax, and accounting services for owners who want help understanding formation and ongoing compliance needs. A review can help identify which agency requirements to verify, while state authorities remain the source for current filing instructions and deadlines.
Common LLC formation mistakes to avoid
A state filing creates an important record, but it does not answer every question about how the business will operate. Watch for these common gaps as you set up the LLC:
- Choosing a state or entity before weighing business goals. Where the business operates can affect taxes and legal requirements. Entity structure can affect paperwork, fundraising, taxes, and personal liability. Do not assume forming in a state where you have no real operations is simpler. Compare the requirements against your plans before filing. The SBA’s business-structure guidance outlines factors to consider.
- Assuming the LLC label selects federal tax treatment. State law creates the LLC. Federal tax classification depends on matters such as member count and elections. The entity name alone does not tell you which tax rules apply. Review the IRS explanation of LLC tax treatment and ask a qualified tax professional about your circumstances.
- Treating a state name search as trademark clearance. A state filing search helps assess whether a name is available for that state’s entity records. It is not a complete review of other trademark rights or planned uses. Check the name for its intended uses before investing in branding.
- Mixing personal and business funds. Keep business income, expenses, and owner contributions documented. Use separate accounts for business transactions. Commingled activity makes bookkeeping and financial review more difficult.
- Overlooking permits and recurring requirements. License and permit needs depend on industry and location, and registration rules vary by state. Check local rules as well. Track the filings and tax duties that apply. The SBA registration overview explains that requirements vary.
- Leaving internal rules and company records unclear. Document ownership, decision-making, and financial arrangements in an operating agreement suited to the LLC. Keep formation documents and important company decisions organized, even if there is only one owner.

Frequently Asked Questions
Can I form an LLC myself?
Many owners complete the filing themselves by following instructions from the state business registry. Confirm the current forms, name rules, registered-agent requirements, and follow-up filings before you submit. If ownership or tax questions are complicated, get qualified guidance rather than guessing. The SBA explains that registration requirements vary by state.
When might my LLC need an EIN?
An LLC generally needs an EIN if it has employees or certain excise-tax filing obligations. Some single-member LLCs without employees or excise-tax liability may not need one for federal tax purposes, though a bank or another requirement may still call for it. Form the LLC through the state before applying. Check the IRS guidance on single-member LLCs for your circumstances.
What LLC requirements change from state to state?
States can differ in registration forms, naming and registered-agent rules, filing procedures, and ongoing reports. Your business location can also affect taxes, zoning, and permits. Check the relevant state and local government sources for current requirements instead of relying on another state’s checklist. The SBA’s registration overview provides a starting point.
Does forming an LLC determine how it is taxed?
No. State law creates the LLC, while federal tax treatment depends on member count and elections. The IRS generally treats a domestic single-member LLC as disregarded for income-tax purposes unless it elects corporate treatment. Multi-member LLCs are generally treated as partnerships unless they elect otherwise. Review the IRS explanation of LLC federal tax classifications and consult a qualified tax professional about your situation.
