Every California employer needs two separate tax ID numbers: a federal Employer Identification Number (EIN) issued by the IRS, and a California employer payroll tax account number issued by the Employment Development Department (EDD). The EIN is nine digits and covers your federal obligations. The EDD number is eight digits, formatted like 000-0000-0, and covers your state payroll taxes.1Employment Development Department. Am I Required to Register as an Employer They are not interchangeable, and your EIN will not stand in for the state number on any California filing. You must register with the EDD within 15 days of paying more than $100 in wages during a calendar quarter, which for most new employers means registering right after the first paycheck goes out.
What Each Number Is For
Your federal EIN identifies your business to the IRS for income tax withholding, Social Security, and Medicare. You use it on Form 941, the Employer’s Quarterly Federal Tax Return, and on every other federal employment tax filing.2Internal Revenue Service. Form 941 – Employer’s Quarterly Federal Tax Return
Your EDD employer payroll tax account number identifies you to California for a completely separate system with its own forms, deposit schedules, and rates. Every quarterly return, wage report, and payment you send the EDD carries this state number. You need your federal EIN in hand before you can complete the state registration, so treat the EIN as step one and the EDD number as step two.
When You Have to Register With the EDD
The trigger is wages, not incorporation. Once you pay more than $100 in wages in a calendar quarter, you have 15 days to register and open a payroll tax account.3Employment Development Department. Employers: Payroll Tax Account Registration Forming your LLC or getting your EIN does not start the clock. Cutting that first paycheck does.
Household employers work off different thresholds. Paying a household worker between $750 and $999.99 in a quarter triggers a duty to withhold State Disability Insurance. Reaching $1,000 or more in a quarter adds Unemployment Insurance and Employment Training Tax obligations for the rest of that year and the year after.1Employment Development Department.

What to Have Ready Before You Register
The EDD’s online system can time out mid-session, so pull everything together first:
- Your nine-digit federal EIN.
- Legal business name, physical location, and mailing address.
- Entity type (corporation, LLC, partnership, or sole proprietorship).
- The date you first paid, or will pay, wages. This sets when your state tax liability begins.
- Full names and Social Security numbers for all corporate officers, partners, or managing members.3Employment Development Department. Employers: Payroll Tax Account Registration
- If you bought or took over an existing business, the previous owner’s EDD account number and the acquisition date. You may have the option to keep the prior owner’s UI rate, which can be lower than the new-employer default.4Employment Development Department. Tax-Rated Employers
How to Register Through e-Services for Business
Registration runs entirely through the EDD’s online portal, e-Services for Business.5Employment Development Department. e-Services for Business Create a user account with a unique ID and password, then choose “New Employer” and follow the prompts.6Employment Development Department. Enroll in e-Services for Business as an Employer The system cross-checks your federal EIN and other identifiers against existing accounts, so you won’t accidentally create a duplicate.
You’ll get an on-screen confirmation once your application goes through. The official account number is typically issued within ten business days, and the EDD follows up with a letter confirming your account number, your assigned UI tax rate, and your quarterly filing schedule.5Employment Development Department. e-Services for Business
What Your EDD Account Covers
All four California payroll taxes report and pay through your single EDD account:
- Unemployment Insurance (UI) is paid entirely by the employer. New employers get a 3.4 percent rate for the first two to three years, then move to an experience-rated rate that ranges from 1.5 to 6.2 percent under the 2026 Schedule F+ schedule. UI applies to the first $7,000 in wages per employee per year.4Employment Development Department. Tax-Rated Employers
- Employment Training Tax (ETT) is employer-paid at a flat 0.1 percent on the same $7,000 base.7Employment Development Department. 2026 Federal and State Payroll Taxes (DE 202)
- State Disability Insurance (SDI) is withheld from employee wages at 1.3 percent for 2026. Since January 1, 2024, there is no taxable wage ceiling, so SDI applies to all wages.8Employment Development Department. Contribution Rates, Withholding Schedules, and Meals and Lodging
- Personal Income Tax (PIT) is withheld from employee wages using the employee’s DE 4 certificate and California’s withholding schedules.
UI and ETT come out of your pocket. SDI and PIT come out of the employee’s paycheck. All four run through the same state account number.
The FUTA Credit Reason to Register Promptly
There’s a direct federal reason not to sit on state registration. Federal unemployment tax (FUTA) is 6 percent on the first $7,000 of wages per employee. Employers who pay their state unemployment taxes on time can claim a credit of up to 5.4 percent against that rate, cutting the effective FUTA cost to 0.6 percent.9Office of the Law Revision Counsel. 26 USC 3302 – Credits Against Tax
Skip the EDD registration and never pay California UI, and you lose that credit. On an employee earning at least $7,000, that turns a $42 annual FUTA bill into $420. The math gets worse with every employee.
Penalties for Skipping or Missing the Registration
The EDD’s penalties stack, and they hit hard when a business ignored the registration requirement:
- Intentional failure to register: $100 per unreported employee, assessed in the quarter with the highest number of unreported workers.10Employment Development Department. Information Sheet: Penalty Reference Chart (DE 231EP)
- Late payment of contributions: 15 percent of the unpaid amount.
- Failure to file electronically: $50 per return, on top of other penalties. All California employers must file returns, wage reports, and deposits electronically, with no minimum-payroll threshold to escape the mandate.11Employment Development Department. E-file and E-pay Mandate for Employers
- Late wage reports after a written demand: $20 per wage item if you still don’t file within 15 days.
- Reports more than 60 days late: an additional 15 percent penalty on unpaid contributions and PIT withholdings.
Interest runs on top of the penalties, and multiple penalties can apply to the same quarter. A business that never registered, missed two quarters, and filed on paper could catch the registration penalty, the late contribution penalty, the electronic filing penalty, and the late report penalty at once.
Registration Only Applies if You Actually Have Employees
None of this triggers if the people working for you are genuinely independent contractors. But California treats worker classification strictly. The IRS common-law test weighs behavioral control, financial control, and the type of relationship, with no single factor deciding the question.12Internal Revenue Service. Independent Contractor (Self-Employed) or Employee California adds its ABC test, which presumes a worker is an employee unless the hiring business proves the worker is free from control, doing work outside the company’s usual business, and running an independently established trade.
Getting classification wrong is where many California businesses run into serious trouble. Misclassification means you never registered when you should have, never withheld SDI or PIT, and never paid UI or ETT. The EDD audits for this, and the penalties above apply to every quarter you were out of compliance. If you’re unsure whether your workers are employees, resolve that question before you decide you don’t need an EDD account.
