California LLC EIN — How to Get Your Federal Tax ID

An Employer Identification Number (EIN) is your LLC's federal tax ID. You need it for your business bank account, hiring employees, filing state and federal tax returns, and California Franchise Tax Board (FTB) registration. Free from the IRS. For the full process, see our CA LLC guide.

California-Specific Notes

FTB uses your EIN: The California Franchise Tax Board identifies your LLC using your federal EIN (not a separate state number). When you file Form 568 (LLC Return of Income), you use your EIN.

SOS file number: The Secretary of State assigns a 12-digit entity number when you file Articles. This is separate from your EIN and used for SOS filings (SOI, amendments).

California employer registration: If you hire employees, register separately with:

• Employment Development Department (EDD) — for state payroll taxes, SDI, PFL
• CA Franchise Tax Board — for employer withholding

FAQ

Can I get an EIN before my Articles are approved?

Technically yes, but the IRS expects your LLC to exist. Best practice: wait until your Articles are filed, then apply immediately.

Do I need a separate EIN for California state taxes?

No. Your federal EIN is used for all FTB filings. However, you receive a separate EDD employer account number if you register for payroll taxes.
