The required documents for an LLC fall into four groups: a formation document filed with your state (the Articles of Organization), an internal governance document (the operating agreement), a federal tax ID (the EIN) with the right IRS forms for your situation, and recurring state filings that keep the company in good standing. A separate set of paperwork comes into play only if you later close the business.
Articles of Organization
This is the filing that actually creates the LLC. You submit it to your state’s Secretary of State or equivalent agency, and once accepted, your business exists as a legal entity with liability protection.1Legal Information Institute. Articles of Organization
Each state uses its own form, but the information requested is largely the same:
- LLC name, which must follow state naming rules and usually include “LLC” or “Limited Liability Company.”
- Principal office address.
- Registered agent, meaning the person or company designated to receive legal and tax correspondence for the LLC. Some states require the agent’s signed consent before you can list them.
- Business purpose. A general statement like “any lawful business” is accepted in many states.
- Duration, which for most LLCs is perpetual.
- Management structure: member-managed or manager-managed.
Official forms are available from your state’s Secretary of State website. Some states also allow you to draft your own document as long as it contains all the required elements.1Legal Information Institute. Articles of Organization
Once the filing is processed, you’ll get either a stamped copy of the document or a Certificate of Formation. Keep it. Banks, landlords, and business partners will ask for it.
Operating Agreement
The operating agreement is the LLC’s internal rulebook. It isn’t usually filed with the state, but it governs how the business actually runs: ownership percentages, voting rights, how profits and losses are divided, management duties, and the process for dissolving the company.
Most states don’t legally require a written operating agreement, but going without one is a mistake.2U.S. Small Business Administration. Basic Information About Operating Agreements Without an agreement, your LLC falls back on your state’s default LLC statute, and those defaults were written for no one in particular. They regularly produce outcomes members didn’t expect, such as splitting profits equally when one member put in far more capital than the other.
Single-member LLCs benefit from one too. The agreement reinforces the separation between you and the business, which is the exact distinction a court looks at when deciding whether to protect your personal assets. Banks and investors also tend to ask for it.
Employer Identification Number
An EIN is a Social Security number for your business. The IRS issues it for free, and you’ll need one to file taxes, open a business bank account, and hire employees.3Internal Revenue Service. Employer Identification Number Multi-member LLCs must have one. Single-member LLCs can technically use the owner’s Social Security number for tax purposes, but getting an EIN keeps your personal number off business paperwork.
Apply online through the IRS website and you’ll get the number immediately at no cost.4Internal Revenue Service. Get an Employer Identification Number The online application runs Monday through Friday, 7 a.m. to 10 p.m. Eastern. Mail or fax applications on Form SS-4 are also available, but they take days or weeks.
Federal Tax Forms
There is no single “LLC tax form.” Which forms you file depends on how many members the LLC has and whether you’ve elected a different tax classification.
Default Classification
A single-member LLC is a “disregarded entity” by default. The IRS ignores it for income tax, and you report business income and expenses on Schedule C of your personal Form 1040.5Internal Revenue Service. Single Member Limited Liability Companies A multi-member LLC is taxed as a partnership by default. The LLC files Form 1065 and issues each member a Schedule K-1 showing their share of income, deductions, and credits.6Internal Revenue Service. LLC Filing as a Corporation or Partnership
Electing Corporate Taxation
An LLC that doesn’t want the default can file Form 8832 to be taxed as a corporation.7Internal Revenue Service. About Form 8832 From there, some LLCs file Form 2553 to elect S corporation status, which can reduce self-employment taxes in the right circumstances. The election generally can’t take effect more than 75 days before or 12 months after you file it, so timing matters.8Internal Revenue Service. Limited Liability Company (LLC)
Employment Tax Forms
If the LLC has employees, you’ll file Form 941 (Employer’s Quarterly Federal Tax Return) for wages, federal income tax withheld, and Social Security and Medicare taxes. Form 940 covers federal unemployment tax. These apply regardless of income tax classification. Even single-member LLCs are treated as separate entities for employment tax.8Internal Revenue Service. Limited Liability Company (LLC)
State Filings That Keep the LLC Alive
Formation is the start of your paperwork, not the end. A few recurring and situational filings keep the entity in good standing.
Annual or Biennial Reports
Most states require an annual or biennial report that updates basic information: registered agent, principal address, member or manager names. A few states don’t require one at all. Others use names like “statement of information.” Fees vary widely, from nothing to several hundred dollars. Miss the deadline and the state can impose late fees or, eventually, administratively dissolve the LLC, which strips your liability protection until you reinstate.
Amendments to the Articles of Organization
Change the LLC’s name, registered agent, principal address, or management structure, and you need to file an amendment with the state. Expect member consent and a filing fee. Outdated public records can cause you to miss legal notices sent to the wrong address or agent.
Foreign Qualification
If your LLC does business in a state other than where you formed it, that state treats you as “foreign” and requires registration there. You file an application, often called an Application for Certificate of Authority, with that state. Most states also require you to appoint a registered agent in-state and provide a Certificate of Good Standing from your home state showing you’re current on filings and fees.
Publication Requirements
A small number of states require newly formed LLCs to publish a notice of formation in local newspapers for a set number of weeks. Costs depend on local advertising rates and range from under $100 to over $1,000. Check your Secretary of State’s website; most states have no publication requirement at all.
Beneficial Ownership Information Reporting
The Corporate Transparency Act originally required most LLCs to file a Beneficial Ownership Information (BOI) report with the Financial Crimes Enforcement Network (FinCEN), disclosing the people who own or control the company. In March 2025, FinCEN issued an interim final rule exempting all entities created in the United States from this requirement.9Financial Crimes Enforcement Network. Beneficial Ownership Information Only entities formed under foreign law and registered to do business in a U.S. state still need to file. FinCEN has also stated it will not enforce BOI penalties against U.S. citizens or domestic companies.10Financial Crimes Enforcement Network. FinCEN Removes Beneficial Ownership Reporting Requirements for U.S. Companies and U.S. Persons If you formed your LLC domestically, no BOI report is required.
Dissolution Documents
Closing an LLC takes paperwork too. Walk away without formally dissolving and you’ll keep owing annual fees and tax filings.
With the state, file Articles of Dissolution (sometimes called a Certificate of Cancellation) with the same office that handled your Articles of Organization. Most states expect you to settle debts, distribute remaining assets to members, and wind down operations first. If the LLC registered as a foreign entity elsewhere, file a withdrawal or cancellation in each of those states.
With the IRS, LLCs taxed as partnerships file a final Form 1065 for the year of dissolution with the “Final Return” box checked. Single-member LLCs file a final Schedule C. An LLC that elected C corporation tax treatment must file Form 966 (Corporate Dissolution or Liquidation) within 30 days of adopting a plan of dissolution.11Internal Revenue Service. Closing a Business Make final federal tax deposits and file any outstanding employment tax returns if the LLC had employees.
Where to File and What It Costs
Most LLC documents go to the Secretary of State (or equivalent) in your state of formation. Nearly every state now offers online filing, with faster turnaround and immediate confirmation. Paper filing by mail or in person is still available in most states.
Formation fees range from under $50 to over $500. Most states fall between $50 and $200. Annual report fees are even more variable, from zero in states that charge no fee or don’t require a report, to several hundred dollars where fees are combined with franchise taxes. Factor in both the initial and recurring costs before picking your state of formation. An LLC formed in a low-fee state that operates elsewhere pays foreign qualification fees on top of its home state costs.
