How do I get an EIN for my LLC?

Apply online at IRS.gov/EIN. The online application is available Monday–Friday, 7am–10pm ET. It takes about 5 minutes and you receive your EIN immediately. You can also apply by fax (4 business days) or mail (4–5 weeks), but the online method is always fastest.

What are the most common EIN application mistakes?

The most common errors: applying before your LLC is officially approved by the state, using the wrong entity type (selecting 'sole proprietor' instead of 'LLC'), entering your personal name instead of the LLC's legal name, or applying for a second EIN when you already have one (the IRS will reject duplicate applications).

Can I use my EIN immediately after receiving it?

Yes for most purposes. However, the IRS system takes 2 business days to fully propagate your new EIN. Some banks and FinTechs may not be able to verify it immediately. If a bank says your EIN is 'not found,' wait 48 hours and try again.

What is the difference between an EIN and a Social Security Number for business?

An EIN (Employer Identification Number) is a federal tax ID for your business entity. Using your SSN for business exposes it to vendors, clients, and 1099 issuers — increasing identity theft risk. An EIN keeps your SSN private and is required for LLCs to open business bank accounts.
