LLCs and corporations register with the Secretary of State in the state where they operate. Sole proprietors and partnerships may only need a DBA if they use a trade name. Many cities and counties also require a local business tax receipt or license. Federal registration is usually just your EIN with the IRS.
Registration levels
| Level | What it is | Who usually needs it |
|---|---|---|
| State entity filing | Articles of organization or incorporation | LLCs and corporations |
| DBA / fictitious name | Registers a trade name | Anyone operating under a name other than their legal name |
| Local business tax or license | City or county registration | Many businesses, rules vary by city |
| Federal | EIN with the IRS | Employers, LLCs, corporations, partnerships; optional for some sole props |

Florida and Texas examples
Florida filings go through the Division of Corporations (Sunbiz). Texas filings go through the Secretary of State SOSDirect system. See our Florida and Texas guides.
Worked example
Luis is opening a lawn care business as an LLC. He files formation documents with the Secretary of State, then checks his county and city for local business tax receipts and licenses. Because he will sell some products, he registers with the state revenue department for sales tax. He records each registration with its number, renewal date and agency contact in one spreadsheet.
Common mistakes
- Registering in the wrong state
- Skipping local registration
- Missing annual reports
- Paying third-party services for free forms without realizing
After registering
Save the confirmation and filing documents, note the annual report due date, set up a registered agent if required, and update your bank, insurer and licenses with the registered legal name. Then move on to tax registrations and local licenses.
Common questions
Do I need to register a sole proprietorship?
Often only if you use a trade name (DBA) or your city requires a local license. Check your state and city.
Where do I register an LLC?
With the Secretary of State (or equivalent) in your state, usually online.
Do I need to register in every city I work in?
Some cities require a local business license or tax registration if you do business there; check each one.
Can I use a registration service?
Yes, but official state sites list the forms and fees directly.
How long does state registration take?
Online filings are often processed within days, but timing varies by state and season. Check your state's posted processing times.
