You've found the person. You've shaken hands, maybe even promised a start date. And now you're sitting at your kitchen table staring at a browser tab that says something like "Form I-9" and wondering why nobody warned you that becoming a boss comes with a stack of paperwork thick enough to use as a doorstop.
I remember hiring my first employee. I had a signed offer letter and a vague sense that I needed to "do some tax stuff." Three weeks later I got a letter from the state unemployment office informing me I owed back contributions plus a small penalty, because I hadn't registered as an employer within the required window. That penalty was $84. Cheap lesson, in hindsight. I've met people who learned it for thousands.
Here's the thing: the legal steps for hiring your first employees aren't complicated individually. There are maybe eight or nine of them. The problem is that nobody hands you the list in order, and the deadlines are real. Miss one and you're not just disorganized — you're non-compliant.
Key Takeaways
- Get your EIN before anything else — you can't do payroll, most banking, or any tax filing without it.
- Form I-9 must be completed for every hire: Section 1 by the employee on day one, Section 2 by you within 3 business days.
- Register with your state's unemployment insurance agency — this is the step most first-time employers skip, and it's the one that generates penalty letters.
- Workers' comp coverage requirements vary enormously by state. Some require it with one employee, some with four or five.
- Classify correctly from the start. Misclassifying an employee as a contractor is the most expensive mistake on this list.
- Payroll taxes are due quarterly or monthly, not annually. Set up the calendar before the first paycheck, not after.
Before the first paycheck: what has to be in place
The order matters here, and it matters for a practical reason: each step unlocks the next one. You can't register for state withholding until you have a state tax account, and you usually can't open that account cleanly until you have a federal EIN. So work down the list.
The EIN and your business structure
Your Employer Identification Number is a free nine-digit number from the IRS. Apply online and you'll typically have it the same session. If you're a sole proprietor with no employees you may have been using your Social Security number for everything — that stops now. Once you hire, you need the EIN, both to file employment tax returns and to keep your personal SSN out of the payroll paperwork.
Here's what the blog posts don't tell you: if you're operating as an LLC, how you're taxed changes what happens next. A single-member LLC taxed as a disregarded entity still has to file employment taxes under its own EIN, and some states want the LLC registered as an employer separately from the owner. I've watched people spend an afternoon on hold with a state agency because they assumed their LLC's existence automatically registered them as an employer. It doesn't.
State registrations you probably haven't heard of
Three separate state accounts typically need to exist before your first pay run:
- State income tax withholding account — so you can withhold and remit the employee's state tax.
- State unemployment insurance (SUI/SUTA) account — you pay this tax on wages, and the rate you're assigned depends on your history. New employers usually get a standard new-employer rate for the first year or two.
- Workers' compensation policy — in most states this is mandatory, and it's a policy you buy, not an account you register. A handful of states run their own monopolistic funds instead of allowing private carriers, which changes your shopping process entirely.
Which brings up something I wish someone had told me: the workers' comp threshold is not the same everywhere. Some states require coverage the moment you hire one employee. Others exempt small headcounts, or count only full-time equivalents. Do not assume your neighbor's experience applies to you if they're across a state line.
The paperwork that has to happen on or near day one
Two federal forms dominate the first week, and they have completely different rules about who fills out what.
New employee Forms I-9: who fills what, and when
Form I-9 verifies identity and work authorization. It is not optional, it is not waivable for people you trust, and it applies to every single hire including US citizens.
The mechanics trip people up. Section 1 is completed by the employee — no later than their first day of work for pay. They attest to their status and provide their information. Section 2 is completed by you, the employer, and it must be done within 3 business days of the start date. In Section 2 you physically examine original documents from the Lists of Acceptable Documents and record which ones you saw.
The employee chooses which documents to present. You cannot ask for a specific combination, and you cannot ask for more than the minimum needed to satisfy the form. That rule exists to prevent discrimination, and it's enforced. If a candidate offers a passport, that alone satisfies both identity and authorization — take it and move on.
New employee Forms W-4 and withholding
The W-4 tells you how much federal income tax to withhold. Your employee fills it out; you don't. Since the form was redesigned a few years back, it no longer uses allowances, so any payroll software you use should be current enough to handle the newer version. If you're running payroll by hand in a spreadsheet — and I did this for exactly one pay period before giving up — make sure you're using current withholding tables, because the old ones will produce the wrong number and the employee will be the one to notice.
Many states have their own withholding certificate. New York, California, and a long list of others will not accept the federal W-4 as a substitute. This is exactly the kind of thing that sits undiscovered until a state notice arrives.
What you owe, and when
Once someone is on payroll, a recurring calendar starts whether you're ready for it or not. The main pieces:
| Obligation | What it covers | Typical rhythm |
|---|---|---|
| Federal income tax withholding | Employee's federal tax | Deposited monthly or semi-weekly, depending on your liability |
| FICA (Social Security + Medicare) | Split between you and the employee | Deposited on the same schedule as withholding |
| FUTA | Federal unemployment tax, employer-paid only | Quarterly, once liability crosses the threshold |
| Form 941 | Quarterly reconciliation of what you withheld and deposited | Four times a year |
| Form W-2 | Annual wage statement to each employee | Once a year, by the end of January |
| State unemployment (SUTA) | State jobless benefits fund | Quarterly, deadline varies by state |
Real talk: the deposit schedule is the part that catches people. If your total employment tax liability crosses a certain threshold in a lookback period, you get moved from monthly to semi-weekly deposits. It's not a punishment, it's just the rule, but it means your payday rhythm can change without anyone mailing you a heads-up.
Employee or contractor? Get this wrong and it costs the most
This is the single biggest legal risk in your first hire, and it deserves more attention than it gets. If you treat someone as an independent contractor when they're functionally an employee, you can be on the hook for the employee's share of payroll taxes that you never withheld, plus the employer share, plus penalties and interest. The bill arrives years later, after the person has moved on.
The test isn't what you call them in the contract. It's about control: do you set their hours, direct how the work is done, provide the tools, and can they work for competitors? A contractor controls their own methods and schedule. If you're managing someone like a member of staff, they're staff.
Posters, records, and the boring stuff that still matters
Federal law requires you to display certain workplace posters covering minimum wage, safety, discrimination, and family leave. Your state adds its own. Most are downloadable free from the relevant agency. Print them. Hang them where employees actually walk.
Then there's recordkeeping. Keep I-9s for the duration of employment plus a set period afterward. Keep payroll records showing hours, wages, and deductions. Keep the W-4s. If a wage dispute or an audit ever lands on your desk, the documentation you kept is the only thing standing between you and a bad outcome.
Minimum wage, overtime, and how you pay people
If you pay hourly, you owe overtime at one and a half times the regular rate for hours over 40 in a workweek — that's federal, and many states set a lower threshold or a higher multiplier. Salaried does not automatically mean exempt. The exemption tests involve both a salary floor and job duties, and getting them wrong means someone you thought was exempt is owed back overtime.
If you pay tipped employees, there's a separate set of rules about tip credits that vary by state. If you hire someone under 18, there are hour and equipment restrictions layered on top. These aren't edge cases — they're the reason a fifteen-minute conversation with an employment attorney before your first hire is worth the money.
The order I'd actually do this in
If I were starting from zero again, here's the sequence:
- Confirm your business structure is registered and your EIN is in hand.
- Register for state withholding and unemployment accounts.
- Buy workers' comp if your state requires it at your headcount.
- Set up payroll software — even at one employee, manual payroll is a false economy.
- Prepare the offer letter, the W-4, the state withholding form, and a blank I-9.
- Day one: employee completes I-9 Section 1 and the W-4.
- Within 3 business days: you complete I-9 Section 2 after examining original documents.
- Hang the posters. File the records. Put the quarterly deadlines in your calendar with reminders.
The regulatory piece is genuinely manageable for a first hire. What sinks people isn't complexity; it's the assumption that the business registration they did months ago already covered all of this. It didn't.
So here's the question worth sitting with: if the state sent you a notice tomorrow asking for your employer account number and your first quarterly filing, could you produce both without opening a single browser tab? If the answer is no, you know exactly which line on that list to finish this week.
