How to Hire Your First Employee Without Breaking the Law

There's a moment in every growing business where you realize you can't do it all yourself anymore. You're turning down work, missing deadlines, or just grinding yourself into dust. It's time to hire someone. Exciting, right?

It is — until you realize that bringing on an employee turns you into an employer, and being an employer comes with a pile of legal obligations that nobody warns you about. Miss one of them and you're looking at fines, back taxes, or worse. So let's walk through what actually has to happen before that first person starts working for you.

Before You Hire: The Accounts You Need

The moment you decide to hire an employee — not a contractor, an actual employee — you trigger a cascade of registration requirements. Most of these take a few minutes each, but they all need to be done before your new hire's first day.

Employer Identification Number (EIN). If you don't already have one, get it from the IRS website. It's free and takes five minutes. This is your business's tax identity as an employer, and you'll need it for everything that follows.

State employer registration. Your state's tax or revenue agency requires you to register as an employer for state income tax withholding. Some states make this automatic when you register your business. Others require a separate filing. Check your state's department of revenue website.

State unemployment insurance (SUTA). You're required to pay into your state's unemployment fund. This means registering with your state's workforce or employment agency. The rate varies by state and by your industry's claims history — new employers typically get a standard starting rate.

Workers' compensation insurance. In almost every state, you're required to carry workers' comp insurance the moment you have one employee. This covers medical expenses and lost wages if an employee is injured on the job. A few states (Texas, for example) make it optional, but even in those states, going without it is a significant risk. If someone gets hurt and you don't have coverage, you're personally liable for their medical bills and lost income.

The Paperwork: What Your New Hire Fills Out on Day One

Form W-4. This is where the employee tells you how much federal income tax to withhold from their paycheck. They fill it out, you keep it on file. Many states have their own version of the W-4 as well.

Form I-9. This verifies that your employee is legally authorized to work in the United States. Both you and the employee have to complete it, and the employee has to provide documents proving identity and work authorization (a passport, or a driver's license plus a Social Security card, for example). You must complete Section 1 on or before the first day of work, and Section 2 within three business days. Keep the I-9 on file — don't send it to the government, but have it ready in case of an audit.

State new hire reporting. Federal law requires you to report new hires to your state's designated agency within 20 days (some states require it faster). This is used to enforce child support orders and detect unemployment fraud. It's a quick form — name, address, Social Security number, date of hire — but skipping it can result in fines.

Payroll: The Part That Trips Everyone Up

As an employer, you're responsible for withholding the right amounts from your employee's paycheck and sending those amounts to the correct government agencies on the correct schedule. This includes federal income tax, state income tax (in most states), Social Security tax (6.2% of wages, matched by you), and Medicare tax (1.45% of wages, also matched by you).

That "matched by you" part catches new employers off guard. When you hire someone at $50,000, your actual cost isn't $50,000. It's the salary plus your half of FICA (7.65%), plus SUTA, plus workers' comp. A reasonable estimate is that your true cost is 1.25 to 1.4 times the base salary, depending on your state and what benefits you offer.

Get a payroll service. I know it's another expense, but doing payroll manually means calculating withholding tables, making tax deposits on the right schedule (semi-weekly or monthly, depending on your liability), filing Form 941 quarterly, filing Form 940 annually, issuing W-2s at year-end, and keeping records for at least four years. A payroll service handles all of that for $40–$80 a month. It's worth every penny.

The Classification Question: Employee vs. Contractor

I covered this in the tax mistakes article, but it's worth reinforcing here because it's the single most expensive mistake new employers make. You don't get to decide whether someone is an employee or a contractor based on what's convenient for you. The IRS looks at the nature of the relationship — do you control when, where, and how the work is done? If yes, that person is almost certainly an employee.

The consequences of getting this wrong are severe: back employment taxes (your share and theirs), penalties, interest, potential state-level fines, and possible criminal liability for willful misclassification. If you're not sure, default to employee. It's always safer to over-classify than under-classify.

The Things People Forget

Labor law posters. Federal and state law requires you to display certain posters in your workplace — minimum wage, OSHA rights, anti-discrimination, Family and Medical Leave Act (if applicable), and others. There are a lot of them, and they vary by state. You can order a complete set from your state's department of labor or buy an all-in-one compliance poster for about $30.

An employee handbook. Not legally required in most states, but practically essential. A handbook sets expectations, documents your policies on things like PTO, anti-harassment, and disciplinary procedures, and gives you something to point to if you ever need to terminate someone. Having written policies that the employee acknowledged in writing is one of the best defenses against wrongful termination claims.

Overtime rules. Unless your employee meets the criteria for an overtime exemption (which is based on both their salary level and their job duties), they're entitled to time-and-a-half for every hour worked over 40 in a week. This is federal law, and some states have even stricter rules. Misclassifying someone as "exempt" when they're not is a wage-and-hour violation with real teeth — liquidated damages, meaning you owe double the unpaid overtime, plus the employee's attorney's fees.
