How Long Does It Take to Register a Business?

Quick Answer

Registering a business takes 1 day to 4 weeks depending on your business structure and state. A sole proprietorship with a DBA can be set up in a single day, while forming a corporation in a state with slower processing can take 3–4 weeks. Most LLCs are approved in 1–2 weeks with standard filing.

Timeline by Business Structure

Business Type	Filing Time	Total Time to Operate
Sole proprietorship	Same day	1–3 days (DBA + EIN)
DBA/Doing Business As	1–5 business days	1–7 days
LLC	3–15 business days	1–4 weeks
Corporation (C-Corp or S-Corp)	5–20 business days	2–4 weeks
Partnership	3–15 business days	1–3 weeks
Nonprofit	5–20 business days (state) + 3–6 months (IRS 501(c)(3))	3–6 months

Step-by-Step Registration Timeline

1. Choose Your Business Structure (1–3 Days)

Research and decide on the structure that best fits your needs. Sole proprietorships are simplest. LLCs offer liability protection with moderate paperwork. Corporations are best for raising investment capital.

2. Register Your Business Name (1–7 Days)

You’ll need to check name availability through your state’s Secretary of State website. If you’re operating under a name different from your legal name, file a DBA (also called a fictitious business name or trade name). DBA registration is typically handled at the county level and takes 1–5 business days.

3. File Formation Documents (3–20 Business Days)

For an LLC, you file Articles of Organization. For a corporation, you file Articles of Incorporation. Processing times vary widely by state:

• Fastest states (1–3 business days): Colorado, Iowa, Missouri, New Hampshire, Wyoming
• Moderate states (5–10 business days): California, Florida, Texas, New York
• Slowest states (15–20+ business days): Maryland, Massachusetts, Maine

4. Get an EIN (Instant–Same Day)

Applying for an Employer Identification Number through the IRS website takes about 5 minutes and the number is issued immediately. You can apply online Monday–Friday, 7 a.m.–10 p.m. Eastern. Mail and fax applications take 4–6 weeks.

5. Register for State Taxes (1–7 Days)

Depending on your state, you may need to register for sales tax, employer withholding, or other state-specific taxes. Most states offer online registration that processes within a few business days.

6. Obtain Licenses and Permits (1–30 Days)

Required licenses vary by industry, state, and locality. Common ones include general business licenses, professional licenses, health permits, and zoning permits. Some are issued same-day; others require inspections.

Expedited Filing Options

Most states offer expedited processing for an additional fee:

Speed	Typical Fee	Processing Time
Standard filing	$50–$300 (varies by state)	5–20 business days
Expedited	+$50–$100	2–5 business days
Same-day/24-hour	+$100–$500	Same day or next business day

Online filing services like LegalZoom, ZenBusiness, and Incfile can handle the paperwork for you, but they don’t speed up actual state processing times beyond what expedited fees achieve.
