What HR Deadlines Apply When a Small California Business Is Sold?

In an asset sale, the state’s wage manual treats the sale as a termination, so the seller owes final wages on the closing date and the buyer registers the workers as new hires. In a stock sale the employer entity stays the same, which changes most of those steps. Check which kind of deal you have first.

I hold a J.D. and an MS-HRM, I am not an attorney, and this guide is for owners of small California teams who are buying or selling. I mark every point that is my inference, and your deal attorney should confirm the structure. My guide to California layoff notices covers closings and layoffs, so this one stays on the people side of a sale.

Does it matter if the deal is a stock sale or an asset sale?

It decides almost everything. In a stock sale the buyer acquires the owners’ shares and the company keeps employing the same people under the same tax and payroll accounts. In an asset sale the buyer acquires equipment, contracts and goodwill and takes on the staff as a new employer.

The language of the DLSE’s enforcement manual is blunt about the second case. It says a sale of the business constitutes a termination of the employment and cites Chapin v. Fairchild Camera. I did not find a DLSE statement about stock sales, and I read the logic as pointing the other way, since the employer does not change. Ask your attorney to say which kind of deal you have in writing, because the rest of this guide depends on it.

When is final pay due to the seller’s employees?

On the day the sale ends their employment, if the manual’s reading applies. Labor Code 201(a) makes wages due and payable immediately when an employer discharges an employee. Applying that rule on the closing date is my inference from the manual’s termination statement, not a quotation of it.

Plan for the cost. Final pay includes earned wages, and under Labor Code 227.3 vested vacation is paid at the final rate. A seller who skips this step risks the waiting time penalties I explain in my guide to final paycheck rules.

The usual fix is a written agreement. The seller can pay final wages and the buyer can rehire everyone, or the buyer can assume the accrued vacation liability and the employee can consent in writing. I did not verify whether California permits that rollover, so treat it as a question for counsel, not a shortcut.

Who is responsible for layoff notices?

Under the federal rule, the seller up to the effective date and the buyer after it. The federal statute, 29 USC 2101(b)(1), makes the seller responsible for notice through the effective date of the sale, and employees of the seller then count as the buyer’s. The regulation at 20 CFR 639.4(c) puts notice of a closing after that date on the buyer.

Both notice laws have size thresholds, which keep many small teams out. Federal law reaches employers with 100 or more employees. The state law, Labor Code 1400.5, reaches an employer that employed 75 or more persons within the preceding 12 months and requires 60 days of notice. I found no sale-of-business provision in the state statute, which I say plainly because someone will ask. If you are at or above the state threshold, call your attorney before you announce anything.

What happens to health coverage?

That depends on the deal and the size of the plan. The federal COBRA regulation, 26 CFR 54.4980B-9, says a stock sale is not a qualifying event for employees who stay. In an asset sale, the same regulation says responsibility depends on the buyer’s status as a successor employer, and the parties can allocate it by contract.

Federal COBRA also has a small employer exception for employers under 20 employees. California fills part of that gap with Cal-COBRA, which runs up to 36 months under Health and Safety Code 1366.27 and applies to insured plans. The two systems do not overlap, because Cal-COBRA excludes people who are eligible for federal COBRA. My glossary entry on Cal-COBRA explains the basics. I did not verify election and notice deadlines, so ask your carrier for the dates in writing.

What does the buyer file with the state on day one?

Registration, then new-hire reports and notices. The Employment Development Department treats a change of ownership as a change you report, and I confirmed the 15-day window in Unemployment Insurance Code 1086. A buyer that acquires part or all of a business may be able to take over the seller’s reserve account under sections 1051 to 1053, and the application window I confirmed is 90 days. EDD’s own form says up to three years for complete acquisitions, so I do not state a deadline here and recommend asking EDD directly.

For employees, the buyer’s duties follow the new-hire pattern.

• Report each person to EDD on a DE 34 within 20 days of the start date, since EDD treats acquired workers as new hires.
• Give each person a written pay notice under Labor Code 2810.5 at hire. Whether an acquisition triggers a new notice is my inference.
• Carry workers’ compensation from the first day, under Labor Code 3700.

What about I-9s and the employees’ paperwork?

The buyer has a choice, with a catch. A successor in interest may elect to obtain and maintain the seller’s I-9 forms, per 8 CFR 274a.2(b)(1)(viii)(A)(7), or it may treat the workers as new hires and complete new forms within three business days of the start date. If you inherit the forms, you inherit any errors in them. My glossary entry on the I-9 covers the form itself, and a quick audit of the seller’s file before closing costs far less than a penalty after it.

Can the buyer require a noncompete from the seller’s staff?

Not from ordinary employees, and the owner is the exception. Business and Professions Code 16601 lets a person who sells the goodwill of a business or all of their ownership interest agree not to compete in a specified geographic area where the business was carried on. Sections 16600, 16600.1 and 16600.5 void employee noncompetes, and my guide to the California noncompete ban explains the rest.

The practical split is simple. Put the restriction in the sale agreement with the owner who is selling, and leave the staff’s offer letters free of it. A noncompete that the buyer asks a regular employee to sign is void and creates a problem.

How should you tell the team?

Tell them early, in writing and in a meeting, once the deal is certain enough to say out loud. Employees in a small business hear about a sale quickly, and silence is read as bad news. The message needs four facts: who the employer will be after closing, whether pay, title and schedule stay the same, what happens to accrued vacation and sick leave, and who to call with questions.

Keep the promises inside what the sale agreement says. A manager who tells staff “nothing will change” and then watches the buyer change the benefit plan has created a problem that the contract cannot fix. If you do not know an answer, say so and give the date you will.

Who answers for the seller’s unpaid wages?

Possibly the buyer, under a rule I read with care. Labor Code 200.3 addresses successor liability for a final judgment on wage claims, and it lists four criteria I will not paraphrase from memory, so read the section. I did not verify how the Fair Employment and Housing Act treats successors. The DLSE manual also describes a priority lien for unpaid wages, and the practical lesson holds either way: audit the seller’s payroll before you close.

What should you do this week?

Get the facts that decide your path.

• Confirm in writing whether the deal is a stock sale or an asset sale.
• List every employee with accrued vacation, accrued sick leave and pay status.
• Ask the carrier, the payroll provider and your attorney for their closing-date requirements.
• Pull the seller’s I-9 and payroll files for a quick audit.

If you want a second reader before closing, my HR compliance check-up reviews the people records on either side of the deal. If you need someone to run the transition, my fractional HR service covers the first months.
