How to Register for a California Payroll Tax Number

If your California business has paid more than $100 in wages to employees in a single calendar quarter, you have 15 days to register for a California payroll tax number with the Employment Development Department.¹ The fastest route is online through the EDD’s e-Services for Business portal. What you receive is an eight-digit employer payroll tax account number that identifies your business on every return, deposit, and notice from the EDD going forward.

When You Have to Register

The commercial trigger is low. Once total wages to all employees in a calendar quarter cross $100, the 15-day clock starts. Wages include checks, cash, electronic payments, and the fair market value of non-cash compensation like meals or lodging.²

Household employers follow a different threshold. If you hire someone for domestic work and pay $750 or more in cash wages in a calendar quarter, you must register within 15 days. Non-cash compensation such as room and board does not count toward the $750 figure. Paying between $750 and $999.99 in cash wages triggers only SDI withholding; crossing $1,000 adds UI and ETT obligations.²

Confirm the Worker Is Actually an Employee

Registering for a payroll tax account presumes you have employees. California’s ABC test presumes a worker is an employee unless the hiring business can prove all three of the following:

The worker is free from the business’s control and direction over how the work is performed.
The work falls outside the business’s usual operations.
The worker has an independently established trade or business in the same field.³

If you cannot satisfy all three, the worker is an employee and the payroll tax obligations apply. Misclassifying someone means back taxes, penalties, and interest on every dollar you should have been withholding. Independent contractors paid $600 or more in a calendar year must still be reported to the EDD on Form DE 542 within 20 days of the first payment or the signed contract, whichever is earlier.

What to Gather Before You Apply

Collect the following before you start the application so you can finish in one sitting:

Your Federal Employer Identification Number (FEIN) from the IRS. If you have applied but not yet received it, enter “Applied For” in the FEIN field.⁴
The legal business name exactly as it appears on file with the California Secretary of State. Look it up on the Secretary of State’s website if you are not sure.
Entity type: corporation, LLC, partnership, sole proprietorship, or other legal structure.
Physical and mailing addresses for the business.
The date you first paid wages exceeding the $100 threshold.
Full name, title, Social Security Number, and California driver license number for every owner, corporate officer, partner, or LLC member.⁴

Registering Online Through e-Services for Business

The EDD encourages online registration.⁵ First, enroll in e-Services for Business by creating a username and password. You then have 24 hours to verify your email address; miss that window and you have to start enrollment over.⁶

Once enrolled, log in and select “New Employer.” Follow the prompts through the registration application, which asks for the business and personal information above plus a description of your industry and the reason you are registering. After submission, the EDD processes the application and mails your eight-digit account number.⁶

Registering by Paper

If online registration is not practical, download Form DE 1 (Commercial Employer Account Registration and Update Form) from the EDD website, complete it, and submit by mail or fax.⁵ Processing takes longer than the online path.

What to Do Once You Have the Number

Getting the account number is one step. Every time you hire or rehire an employee, you must report that person to California’s New Employee Registry within 20 calendar days of their first day of work. The Report of New Employee(s) is Form DE 34, and you can file it through e-Services for Business, by mail, or by fax.⁷

Skipping that report costs $24 per unreported employee. If the failure stems from a deliberate agreement between you and the worker to avoid reporting, the penalty rises to $490 per employee.⁷

From there, you will file quarterly returns on Forms DE 9 and DE 9C and make tax deposits on a schedule tied to the amount of personal income tax you accumulate. Your account covers four state payroll taxes: Unemployment Insurance and Employment Training Tax, which you pay as the employer, and State Disability Insurance and Personal Income Tax withholding, which you deduct from employee wages and remit on their behalf.

Finding an Account Number You Already Have

If your business is already registered but you cannot locate the eight-digit number, check any previously filed Form DE 9 or DE 9C, where it appears in the format XXX-XXXX-X. It is also displayed on the dashboard when you log in to e-Services for Business. If neither works, the EDD Taxpayer Assistance Center can retrieve it for you.

Updating the Account After Registration

Use e-Services for Business to notify the EDD when the business changes. Updates to legal name, ownership, entity type, or a closure all need to be reported promptly.⁴ An out-of-date account creates mismatches with your filings that surface at the worst times, usually during an audit or when an employee files a benefit claim.
