Comprehensive filing requirements and step-by-step guidance from business experts
Ensure your business filing meets all legal requirements and state regulations
From name selection to final filing - get everything you need to launch your business
Filing a business involves more than completing a single form. Depending on your entity type and the states where you will operate, you may need to file with multiple government agencies at the state, county, and federal levels. Understanding what each filing accomplishes — and what it does not — prevents costly mistakes like believing you are protected when crucial steps remain incomplete.
The most important principle: no single filing creates a fully operational, legally protected business. State entity formation gives you an officially recognized legal entity. EIN registration gives you a federal tax identity. Business license gives you permission to operate in your locality. Trademark filing gives you brand name protection. Each layer serves a distinct purpose, and skipping any layer leaves a gap in your business infrastructure.
| Entity Type | Filing Document | Where to File | Average Timeline |
|---|---|---|---|
| LLC | Articles of Organization | State Secretary of State | 1-15 business days |
| Corporation | Articles of Incorporation | State Secretary of State | 1-15 business days |
| General Partnership | Partnership Agreement (voluntary) + DBA | County Clerk (for DBA) | 1-5 business days |
| Sole Proprietorship | DBA registration (if using trade name) | County Clerk or State | Same day to 5 days |
| Nonprofit Corporation | Articles of Incorporation + IRS Form 1023 | State SOS + IRS | 3-12 months (IRS approval) |
Regardless of entity type, the foundational formation document requires several standard elements: (1) The official entity name, including the required designator (LLC, Inc., etc.); (2) The principal office address — this must be a physical address in most states, not a P.O. Box; (3) The name and address of the registered agent; (4) The purpose of the business (most states accept "any lawful purpose"); (5) The names and addresses of the organizers or incorporators; and for corporations, (6) the number of authorized shares of stock. Optional provisions addressing management structure, membership interests, or special governance rules are typically placed in an Operating Agreement (LLC) or Bylaws (Corporation) rather than the Articles themselves.
Filing your business entity is the beginning, not the end, of your compliance obligations. Ongoing requirements typically include: Annual Reports filed with the state SOS (due dates and fees vary by state — Delaware's annual franchise tax can be thousands of dollars for corporations with large authorized share counts), maintenance of your registered agent, proper documentation of member/shareholder meetings (more important for corporations than LLCs), and keeping business and personal finances completely separate. Failure to maintain this "corporate formality" can result in courts "piercing the corporate veil" and holding owners personally liable for business debts.
The majority of states now accept — and prefer — online business entity filings through their Secretary of State websites. Online filing is processed faster, reduces errors, and often provides immediate confirmation. Some states (like Wyoming and Delaware) process online LLC formations within hours. A few states still require paper filings for certain entity types or situations. The SOS website for your state will clearly indicate which filing methods are accepted and any differences in processing times or fees between online and paper submissions.
No — forming an LLC or corporation is a straightforward administrative process that many entrepreneurs complete without an attorney. The state's Articles of Organization or Incorporation forms have clear instructions. However, an attorney adds significant value for: drafting a comprehensive Operating Agreement or Bylaws (the internal governance documents), advising on the appropriate entity structure given your tax situation, reviewing co-founder or investor agreements, and ensuring compliance with any industry-specific regulations. For a solo founder with a simple business, DIY formation with a careful review of the state's requirements is reasonable. For multi-founder companies, consider attorney assistance for the governance documents even if you file the entity itself independently.
An Operating Agreement is the internal governance document for an LLC that specifies how the company is managed, how profits are distributed, what happens when a member leaves or dies, and how decisions are made. While not always legally required (some states require it; others merely recommend it), an Operating Agreement is strongly advisable for any LLC with more than one member. Without it, your LLC is governed by your state's default LLC statutes, which may not reflect how you and your co-founders actually intend to operate. A well-drafted Operating Agreement prevents disputes and protects all members' interests.
