California · Payroll registration
California payroll tax registration, done for you.
The California clock is tighter than it looks. You have 15 days from paying more than $100 in wages in a quarter to register, and the EDD can take up to ten business days to issue the account number. Those two windows overlap, which is why the first pay run is usually where this becomes urgent.
California employers must register with the Employment Development Department within 15 days of hiring employees and paying more than $100 in wages in a calendar quarter. Enroll in e-Services for Business, choose New Employer, and complete the registration. EDD then issues an eight-digit employer payroll tax account number.
Regcrest is a private filing service, not a government agency. We can prepare and file this registration for you for $180.

California Employment Development Department, payroll registration
State fee. $0. California does not charge to register an employer payroll tax account. Our flat fee covers the registration itself.
Our fee. $180 per state, flat. State fees are passed through at cost.
When you have to register
Registration is required within 15 days after paying more than $100 in wages in a calendar quarter. Most employers cross that threshold on their first pay run, so the window opens and starts closing on the same day. It is a quarterly threshold rather than an annual one, which catches seasonal and one-off employers.
What comes next
Worth knowing what comes next: once the account exists you file the DE 9 and DE 9C each quarter, and if you later close, the final versions of both are due within 10 days of the last wage paid rather than on the normal schedule.
How long it takes
The EDD states that requests for a new employer payroll tax account number can take up to ten business days. That is the number to plan around, because payroll cannot be remitted correctly without it, and it does not shorten because your pay date is close.
What we do
We work out which accounts you need, submit each registration, and hand you the account numbers, rates, and deposit schedules your payroll system asks for. One remote hire. $180 per state, plus state fees at cost. We submit within 2 business days. You keep the client. We never email them.
EDD can take up to ten business days to issue the account number.

What makes California harder than average
- Two clocks running against each other. You have 15 days to register and the EDD can take ten business days to issue the number. Leaving the registration until day fourteen means the account number arrives well after the payroll it was needed for.
- One account is the good news, and it is genuinely unusual. California puts Personal Income Tax withholding, Unemployment Insurance, Employment Training Tax, and State Disability Insurance in a single EDD employer payroll tax account. Most states split withholding and unemployment across two departments.
- The number has its own name and format. You get an eight digit employer payroll tax account number formatted like 000-0000-0, also called a SEIN or State ID number. It is not your FEIN, and payroll software given the wrong one fails without a useful error.
- The threshold is quarterly and low. More than $100 in wages in a calendar quarter is not much. A business that takes on one part-time person for a few weeks is inside the requirement, which surprises people who assume there is a meaningful minimum.
How California compares
What triggers registration in California is not what triggers it next door. The table sets the thresholds side by side.

Who has to register as an employer in California?

When do I have to register with the EDD?
Within 15 days after paying more than $100 in wages in a calendar quarter. It is measured per quarter rather than per year, and most employers cross it on the first pay run.
How long does the account number take?
The EDD says requests for a new employer payroll tax account number can take up to ten business days. Register before you need it rather than when you need it.
Do I need a separate unemployment account in California?
No, and this is where California is simpler than most states. One EDD account covers Personal Income Tax withholding, Unemployment Insurance, Employment Training Tax, and State Disability Insurance.
Is the account number the same as my federal EIN?
No. California issues an eight digit employer payroll tax account number in the format 000-0000-0, sometimes called a SEIN. Your FEIN is separate and both are needed.
What do you need from me to start?
The legal name and FEIN, the entity type, the California business address, the date of your first payroll or first wages over $100, and the officer or owner details the EDD asks for.
