Payroll follows the employee, not the company, and one remote hire changes 3 filings in the first 20 days

For 2 years I told founders that payroll follows the company. Incorporate in Delaware, run payroll where the finance team sits, add people wherever they happen to live. I was wrong about the middle part, and it was bad advice that surfaced the first time a company I work with hired 1 engineer in California and nobody registered anything for 4 months.

So this is how to set up payroll in a new state as I now understand it, built from 3 public sources rather than from a provider’s onboarding checklist. I went looking for the actual rules after that California hire, and reading them took me most of an afternoon, mostly because the 3 layers live on 3 different government websites that never mention each other. When the question turns to where the money sits, Bank Index lists US banks, each with its supervisor and licence status.

The short version, before the detail: payroll follows the employee, not the company. Where the person works decides where you register, where you report the hire and how your federal unemployment tax is calculated.

The layer that is the same everywhere: federal unemployment tax

The federal rules are the easy part, and they set the frame for everything else. The IRS says you owe federal unemployment tax if you “paid wages of $1,500 or more to employees in any calendar quarter”, or if you had 1 or more employees for some part of a day in “20 or more different weeks” in the year.

The rate is “6.0%” on “the first $7,000 you paid to each employee as wages during the year”. Almost nobody pays 6.0 per cent, though, because state unemployment tax earns a credit of up to 5.4 per cent, and with the full credit the rate after credit is 0.6 per cent.

On 1 employee that is the difference between 420 dollars a year and 42 dollars a year on the first 7,000 of wages. The credit is where the new state starts to matter, and I had never connected the 2, because in a company with every employee in 1 state the credit is automatic, invisible and identical every quarter, so nothing ever prompts you to ask what it depends on until a second state quietly changes the answer.

Why a second state changes the federal return

The full 5.4 per cent credit comes with conditions, and 1 of them is about geography. You get the maximum only if you paid state unemployment taxes in full and on time, on the same wages, “and the state isn’t determined to be a credit reduction state”.

That condition needs a definition. A credit reduction state is one that “hasn’t repaid money it borrowed from the federal government to pay unemployment benefits”. Hire in 1 of those and your federal credit for that employee shrinks, so your federal tax goes up, purely because of where the person lives. The Department of Labor decides the list each year. This year’s list was not opened for this piece, so no state is named.

Then there is the form itself. The IRS says you must use Schedule A of Form 940 “if you paid wages to employees in more than one state”. One remote hire in a second state is enough. The return that was a single page last year now has an attachment, and I suspect most founders discover it when their provider asks for the state registration number they never obtained.

The layer that follows the person: new hire reporting

This is the part that has nothing to do with tax, which is exactly why it gets missed. Federal law “requires employers to report basic information on new and rehired employees within 20 days of hire to the state where the new employees work”, and the same page adds that “some states require it sooner”.

Read the destination again, slowly, because it is the whole point: not the state where the company is registered. The state where the new employee works. A Delaware corporation with a New York office hiring 1 person in Colorado reports that hire to Colorado, inside 20 days or less.

The purpose explains the strictness. The reports feed the National Directory of New Hires, which child support agencies use to find a parent who owes support and issue an income withholding order. A missed report is not a tax problem, it is a hole in a system built to reach people, and I find it hard to treat that as paperwork once you have read what it is for.

The layer that differs everywhere: registering in the state

Here the rules stop being federal and become 50 separate answers. I checked 1 of them properly, California, because that is where the story at the top happened.

The instructions for the state’s registration form cite Section 1086 of the California Unemployment Insurance Code, which requires an employer to register with the Employment Development Department “within 15 days after hiring one or more employees and paying wages in excess of $100”. One hundred dollars, and fifteen days.

Put that next to the story. The company hired in March, paid a full salary in the first pay run, and registered in July. By the statute’s own numbers it was late by roughly 3 and a half months on a threshold it crossed in its first week. I do not know what that cost them in penalties, because they settled it through their provider without telling me. The penalty sections were outside this piece, and I am not going to pretend to a number I have not seen.

Why this keeps catching good companies

None of the companies I have seen get this wrong were careless. They had a provider, a bookkeeper and a finance lead, and every one of those people was looking at the company rather than at the employee, because that is how every dashboard in the stack is organised. The payroll tool shows one company. The accountant files for one company. The home state sends its reminders to one company. Nothing in that picture lights up when a person in a different state signs an offer, and so the new state stays invisible until its first letter arrives.

That is also why the fix is a habit rather than a tool. The moment an offer goes out to somebody outside the home state, the question to ask is no longer what the salary is but where the work happens, and the answer to that question is what opens the file for the new state. I would rather a founder asked it once too often than once too late.

There is a quieter reason as well. A remote hire often starts as a contractor and converts later, and conversion day is when the state obligations begin, not the day the relationship started. Founders remember the start date and forget the conversion date, and the conversion date is the one every clock above counts from.

What I would do the week the offer is signed

Treat the employee’s work state as a launch, not as a payroll setting. The day the offer is signed, 3 clocks can start: the state registration clock, the 20 day new hire clock, and the federal credit question for that state.

Register with the state before the first pay run rather than after it, because a threshold as low as 100 dollars in California is crossed by any real salary on the first day of pay. Then report the hire to the state where the person works, not where you are. Then tell whoever prepares Form 940 that there are now 2 states, so Schedule A is expected rather than discovered.

Last step. Check the credit reduction list for that state before you model the cost of the hire. My guess is that it rarely changes the decision, since the difference is small per employee, but it changes the forecast, and forecasts are what founders get questioned on.

Questions we get

These come from founders making their first hire outside the home state, usually in the week between the signed offer and the first pay run, which is exactly the week when every one of the clocks above is already running and nobody on the team has noticed that it started.

When does state withholding registration have to happen? It depends on the state, and I checked only California: registration with the Employment Development Department within 15 days after hiring and paying more than 100 dollars in wages. Every other state sets its own rule.

Do I need an unemployment insurance account in the new state? In practice yes, because the federal credit of up to 5.4 per cent depends on paying state unemployment tax in full and on time. Without the state account there is no state tax paid, and without that there is no credit, which moves the federal rate from 0.6 per cent towards 6.0.

Where does new hire reporting go for a remote employee? To the state where the employee works, within 20 days of hire under federal law, and sooner where a state requires it. The company’s home state is not the destination. I still find that the most surprising line of the three sources.

Does a reciprocity agreement change any of this at all, or is that a separate question? Agreements between states can change which state’s income tax you withhold for someone who lives in one and works in another. I have not read those agreements for this piece, so the honest answer is to ask your provider which agreements apply to your 2 states before the first pay run.

What does multi state payroll change on Form 940? Schedule A becomes mandatory as soon as you pay wages in more than 1 state, or in any state subject to a credit reduction. That is the line most first multi state returns miss, and the reason is almost always the same: the return is prepared from last year’s file, last year there was 1 state, and nothing in last year’s file mentions the person who was hired in a different one in June.

A short digression about the word nexus

People reach for the word nexus here, and it causes more confusion than it saves. Nexus is a sales tax idea about when a state can tax your sales. Payroll obligations are about where a person works, and they arrive with the person, whether or not you sell anything in that state. I am slightly annoyed at how often the 2 get merged in founder chats. Anyway, back to the offer letter.

What is not settled here

The other 49 states. California was checked for registration, and every other state has its own threshold, deadline and form.

This year’s credit reduction list. It is set annually by the Department of Labor, the current edition was not opened here, and neither figure is published anywhere in the 3 sources this piece rests on.

The penalties for late registration or late new hire reports. They exist, they differ by state, and I would rather leave a gap than quote a number I have not read.
