An Employer Identification Number (EIN) is a 9-digit tax ID issued by the IRS for your business — think of it as a Social Security Number for your company. Every LLC, corporation, and most sole proprietors in California need one.
The IRS offers a free online EIN application at IRS.gov/ein. Complete it online and receive your EIN instantly. You'll need your SSN, business address, and entity type.
💡 XbyZ Tip: Apply for your EIN before opening your bank account — most banks require it on the spot.
You need an EIN if your business has employees, operates as an LLC or corporation, withholds taxes on non-wage income, or has a Keogh plan. Even single-member LLCs benefit from having one to keep finances separate.
XbyZ LLC handles EIN registration as part of our Business Setup packages starting at $299.
