This guide covers who must register, how To enroll in EDD e-Services for Business, how To apply for your Employer Payroll Tax Account Number, and post-registration obligations.
1. Overview of California e-Services and State Tax ID
California issues a State Tax Identification Number through the Employment Development Department.
The number is often called an Employer Payroll Tax Account Number or State Employer Identification Number and is required for payroll tax filings and payments.
Who Needs To Register
Any business that pays wages of more than one hundred dollars in a calendar quarter must register with the EDD within fifteen days of meeting that threshold.
This applies to employers who hire one or more employees and are liable for Unemployment Insurance, Employment Training Tax, State Disability Insurance, or Personal Income Tax withholding.
What Is the Employer Payroll Tax Account Number (SEIN)?
The EDD issues an eight digit Employer Payroll Tax Account Number formatted like 000-0000-0.
You will use this number for wage reports, payroll tax returns, payments, and account updates with the EDD.
2. How To Enroll and Register

Processing and Account Issuance

Keep this number on file and update payroll systems, tax software, and any third party payroll providers with the SEIN once received.
