Open the payroll accounts before the first check clears: EDD registration for a California contractor

You have decided to put somebody on. The rate is agreed, the start date is Monday, and the only thing standing between you and a second pair of hands is a stack of state paperwork nobody has ever explained to you in plain language.

Here is the reassuring part, and it is worth reading before the intimidating part. The California payroll tax system has four taxes in it, two of which are yours and two of which are your employee's money passing through your account. Your own share is capped at a few hundred dollars per person per year. The filings happen four times a year on dates that never move. The registration itself is an online form that takes a morning.

The reason it feels bigger than that is that nobody tells you the sequence. So here is the sequence, the four accounts, the quarterly rhythm, and a worked year with real dates on it.

What makes you an employer, and the clock that starts when it happens

You become an employer for California payroll tax purposes when you pay more than $100 in wages in a calendar quarter (EDD). Not $100 a week. One hundred dollars in a quarter, which a single Saturday of help will clear.

From that point you have 15 days to register with EDD (EDD). Registration is done through e-Services for Business, and it issues you an eight digit employer payroll tax account number, which then appears on everything you file for the life of the business.

Two things have to be in hand before you sit down to do it:

• A federal EIN from the IRS. Free, issued online in minutes. EDD registration asks for it.
• Workers comp cover, bound and effective from the first day of work. This is not part of EDD registration, but the two get done in the same week for a reason. Your CSLB license is suspended by operation of law on the day cover lapses or on the day the certification of exemption on your file stops being true (BPC s.7125.2). Registering with EDD while telling CSLB you have no employees is a contradiction that lives in two state databases at once. The mechanics are in workers comp for a California contractor.

Register even if the person is part time, seasonal, family, or "just for this job". None of those words appear in the $100 rule.

The four taxes, and which two are actually yours

Look at what that table says about your actual cost. UI and ETT both stop at the first $7,000 of wages, so a carpenter you pay $70,000 costs you exactly the same in state payroll tax as a carpenter you pay $9,000.

Run the arithmetic once and stop worrying about it:

• UI at 3.4 percent on $7,000 is $238 per employee per year (EDD).
• ETT at 0.1 percent on $7,000 is $7 per employee per year (EDD).
• Your total employer side state payroll tax on that person is $245 for the year, and it is finished by roughly the end of the first quarter they work.

Two hundred and forty five dollars. That is the number people put off for months. The genuine cost of an employee sits somewhere else entirely: the workers comp premium on the classification they work in, the federal side, and the non productive hours you pay for. Where all of that goes in a price is what to charge as a California contractor.

SDI and PIT are not your money at any point. You withhold them, hold them briefly, and remit them. Treat that balance as somebody else's cash sitting in your account, because in law it is.

The rhythm: two returns a quarter, deposits in between

California payroll for a small contractor runs on a loop with three moving parts.

The DE 9 and the DE 9C, quarterly. The DE 9 is the Quarterly Contribution Return and Report of Wages. The DE 9C is the continuation that reports each employee by name, social security number and wages. They are due on the first day of the month after the quarter closes, and they become delinquent if they are not filed by the last day of that month (EDD). When the last day falls on a weekend or a state holiday, it moves to the next business day (EDD).

Deposits, on a schedule EDD assigns you. How often you send the withheld PIT and the SDI is set by how much you are withholding and by your federal deposit schedule (EDD). EDD tells you your schedule when you register and it sits in your e-Services account, so read it there rather than guessing it from what another contractor told you.

Everything electronic. Filing and paying are done electronically through e-Services for Business (EDD). There is no paper lane to fall back into, which is a small mercy: the same login carries the returns, the deposits, the new hire reports and the account notices.

A first year, with dates on it

A C-10 electrical contractor in Fresno puts a first employee on in spring 2026. Every date below is fixed by the rules above, so this is the calendar the whole year runs on.

Notice how little of that is variable. Four filing months, always January, April, July and October, always due on the 1st and delinquent after the last day. Put the four dates in the calendar once, with a recurring annual repeat, and the compliance side of having employees is a solved problem in your business for as long as you have one.

Notice also that the busiest paperwork is at the front. The registration and the new hire report both hang off the start date, and both are counted in days rather than months, which is why the first hire is planned two weeks out rather than announced on a Friday afternoon. The full countdown is in hiring your first employee in California.

New hire reporting, and the one that catches contractors

Two reports, same 20 day shape, different subject.

DE 34, Report of New Employee(s). Filed within 20 days of an employee's start of work date (EDD). It applies to every new employee and to any rehire who has been off your payroll for a stretch. Filed in the same e-Services account as everything else, in about two minutes.

DE 542, Report of Independent Contractor(s). Filed within 20 days of either entering a contract for $600 or more with an independent contractor, or paying $600 or more to one, whichever comes first (EDD). This is the one contractors miss, because a service provider you pay $600 to does not feel like a payroll event.

Which brings up the question underneath all of this. The person you are about to pay: employee or subcontractor? California answers it with the ABC test in Labor Code s.2775, and it presumes employee status unless all three parts are satisfied. Construction gets its own path in Labor Code s.2781, and that path is built around the sub actually being a business: a written subcontract, a valid contractor license from CSLB for the work being performed, their own business license where the city requires one, control of their own workers, and a business that exists independently of you.

That is not a technicality to be argued after the fact. A "sub" who does not clear it is your employee for payroll tax, for workers comp and for wage and hour, retroactively, and the comp piece of that reaches back to your license status under BPC s.7125.2. If the person turns up in your truck, uses your tools and works the hours you set, price them as an employee and register properly. It is cheaper than the alternative by a wide margin, and at $245 a year of employer payroll tax it was never the expensive part.

The records you are building are worth more than the filings

The DE 9C is a certified quarterly statement of who worked for you and what you paid them. That record is the raw material for several other things a growing contractor eventually needs.

If you take public work, certified payroll on a job over $1,000 comes straight out of the same payroll data, submitted electronically at least monthly, with records produced within 10 days of a written request. Registration with DIR is required before you can bid, and it renews on July 1 each year. All of that is in DIR registration and certified payroll, and the wage rates that sit on top of it are in prevailing wage for California contractors.

If you are pricing work properly, your quarterly wage totals are the honest input to your labor burden, which is the number most contractors guess at and then wonder why the year came out thinner than the jobs suggested.

And if you are running a crew at all, the payroll record and the safety record travel together the first time anything goes wrong. What has to exist in writing before anyone starts is in the Cal/OSHA IIPP guide.

Do the registration this week, not on the start date

The sequence is short and it only runs one way: EIN first, workers comp bound and the certificate filed with CSLB second, EDD registration third, then the DE 34 inside 20 days of the start of work.

Do it in that order, in one week, and the person you hire starts on a Monday with everything behind them already true. Do it in the reverse order, and you spend the first quarter fixing a record instead of running a job.

On AEC Stack there is no monthly subscription. The platform fee is 2.5 percent of each invoice processed through the platform, so the job records your quarterly numbers come out of are the same records that produced the invoices.

Set your four filing dates now, then open a working business file and put the registration, the comp policy and the first payroll into one place before Monday.
