California EIN Requirements
If you've formed an LLC in California, getting an EIN (Employer Identification Number) is one of your next critical steps. Here's what California LLC owners need to know.
The basics:
- An EIN is a federal number issued by the IRS
- California doesn't have a separate state tax ID for LLCs
- You'll use your EIN for both federal and California state tax purposes
When California LLCs Need an EIN
Your California LLC must have an EIN if you:
- Have more than one member (multi-member LLC)
- Plan to hire employees
- Need to open a business bank account (most CA banks require it)
- Will file excise tax returns
- Have a Keogh retirement plan
Single-member California LLCs: Technically optional, but strongly recommended because:
- California banks typically require an EIN to open business accounts
- Protects your SSN from exposure on W-9 forms
- Required if you ever hire employees or add members

California-Specific Considerations
Franchise Tax Board Registration
After getting your EIN, California requires:
- Form 568 - Annual LLC return (even if single-member)
- $800 minimum franchise tax - Due annually by the 15th day of the 4th month
- LLC fee - Additional fee if gross receipts exceed $250,000
California Secretary of State
Your EIN is separate from your:
- California LLC file number
- Statement of Information filings
- Business license requirements
After Getting Your EIN
Once you have your California LLC's EIN:
- Open a business bank account - Required for proper LLC separation
- Register with Franchise Tax Board - For California tax obligations
- Get local business licenses - Required in most CA cities
- Set up payroll (if hiring) - California has strict employment laws
- Save your CP 575 letter - Official IRS confirmation
Common Mistakes to Avoid
Using personal address: Use your LLC's registered business address, not your home (unless that's your business address).
Wrong entity type: Select "LLC" even if you've elected S-Corp or C-Corp taxation.
Inconsistent naming: Your LLC name must match exactly what's filed with the California Secretary of State.
