How to add an employee to your LLC, step by step

The first time I helped a friend hire her first employee through her LLC, we spent more time on paperwork than on the actual hire. EINs, state labor accounts, I-9s, operating agreement amendments. She thought “add an employee” meant “post a position and Venmo them.” It does not.

Most LLC owners going from solo to first hire run into the same wall. The hiring part is familiar. The infrastructure underneath it is not. And the IRS, state labor departments, and federal contractor classification rules don’t grade on a curve.

This guide walks through what you actually need to do, in roughly the order you’ll need to do it. Legal plumbing first, then the hiring process itself, then onboarding and the things people miss.

The short version

Get an EIN if your LLC doesn’t already have one, then register with your state’s labor and tax agencies and line up workers’ compensation insurance before you make an offer. Update your operating agreement so it accounts for employees, since most single-member agreements don’t. File the day-one paperwork (Form I-9, Form W-4, state new-hire report) inside the legal deadlines. None of this is legal or tax advice. The specifics vary by state and by how your LLC is taxed, so confirm the details that apply to you with a CPA or business attorney before you file anything.

Confirm you actually want an employee, not a contractor

Before any of the rest of this, ask whether you want an employee or a contractor. The IRS uses three buckets to classify the relationship: behavioral control, financial control, and the type of relationship. If you set the schedule, provide the tools, expect ongoing work, and integrate the person into your operations, you have an employee. If they set their own hours, use their own tools, work for multiple clients, and you pay per project, you have a contractor.

Misclassifying an employee as a contractor is the single most common mistake first-time LLC employers make. It also has the biggest tail. Back taxes, penalties, and unpaid overtime add up fast, and the IRS Form SS-8 is the quickest way to get an official ruling if you are not sure.

If the answer is “employee,” keep reading. If it’s “contractor,” most of the rest of this guide doesn’t apply. You’ll just need a 1099 and a written contract.

Get your federal and state tax accounts in order

You can’t pay an employee without a few federal and state IDs in place. Sort these before you make the offer.

Federal Employer Identification Number (EIN). If your LLC was a single-member LLC reporting on your personal return, you may not have one yet. You need one to run payroll. Apply free directly through the IRS, online, and you get the number immediately. Form SS-4 still exists, but you only need to fill it out if you’re applying by fax or mail. One catch people miss: the IRS says to allow up to two weeks before your new EIN is fully active in its systems for e-filing or electronic tax deposits, so don’t wait until payday to apply.

State labor and unemployment accounts. Every state has its own employer registration. You’ll typically need to register with the state labor department for unemployment insurance, with the state revenue department for income tax withholding, and with workers’ compensation (where required, which is most states once you have any employee).

Workers’ compensation insurance. Required in the large majority of states the moment you hire your first W-2 employee, and Texas is the one state where it’s legally optional for private employers (opting out there comes with its own tradeoffs, since you lose some standard legal defenses if a worker sues). A few states, including Alabama, Mississippi, and Tennessee, exempt general (non-construction) employers with fewer than five workers. Check your state’s specific threshold and shop the policy before you make the offer, since rates vary widely by industry.

Federal payroll withholding. Your EIN gives you access to EFTPS for federal tax deposits. As a brand-new employer with no filing history, the IRS defaults you to monthly depositor status: you owe the federal income tax withholding, Social Security, and Medicare you’ve withheld by the 15th of the following month. That can change in future years based on how much you withhold, but monthly is where you start.

If this is your first employee, the cleanest path is a payroll service like Gusto, Rippling, or QuickBooks Payroll. Each handles federal and state filings, generates pay stubs, and files year-end W-2s. Doing it manually is possible. It is also a great way to spend a Saturday discovering what an EFTPS lockout error looks like.

Update your operating agreement before the offer goes out

LLCs run on operating agreements, and your existing one almost certainly does not anticipate W-2 employees. This matters more than people think.

A few specific things to check.

• Decision rights. Who has authority to hire, fire, and set compensation? In a member-managed LLC, the default is unanimous member consent. That probably is not what you want for routine hires.
• Manager-managed structure. If you’re scaling past one or two employees, consider switching to manager-managed so day-to-day employment decisions don’t require a vote.
• Equity and profit-sharing rules. If you ever plan to grant a stake to an employee, the operating agreement needs to define what that looks like (profits interests, capital interests, phantom equity). LLCs cannot grant traditional stock options the way corporations can.
• Confidentiality and IP assignment. Make sure the agreement either contains these terms or that your employment agreement does. Default state law often does not assign employee-developed IP to the company without a written agreement.

This is the step where a lawyer pays for themselves. A two-hour review of your operating agreement against your first hire’s offer letter costs less than discovering a gap in year three.

Write a position description that fits your LLC

A good position description does two things at once. It attracts the candidates you want, and it sets the legal frame for the role.

• Tie responsibilities to the operating agreement. If your LLC has specific decision-rights rules, the position description should reflect what the role can and cannot do. A “Head of Operations” who can sign vendor contracts up to $25K is a different role from one who can’t sign anything without member approval.
• Be specific about exempt vs non-exempt status. Under the Fair Labor Standards Act, exempt employees are salaried and not owed overtime. Non-exempt employees, salaried or hourly, are owed overtime under federal law. The classification depends on job duties and salary level, not the title you give the role. Get this wrong and you owe back overtime.
• Use inclusive language without being generic. The description should welcome a wide range of candidates and still be specific about what you actually need. Vague descriptions attract everyone and select for nothing.
• Publish the salary range. As of 2026, 18 states plus Washington, D.C. require it for at least some job postings, including California, Colorado, New York, Washington, Connecticut, Hawaii, Illinois, and others, and the list keeps growing. Because these requirements vary by state and by whether the role could be filled remotely, check the current rules for where you’re posting before publishing. Even where it’s not required, ranges filter out wildly mismatched candidates before they apply.

A good rule: if you can’t tell from the description what the person will actually do in their first 90 days, the description isn’t done.

Screen candidates without burning your week

Most LLC owners do not have a recruiting team. The hiring manager is also the operator, the ops lead, and probably the person doing payroll. Phone screens scale terribly under those conditions.

A small structural change helps a lot. Move the first round to a structured candidate-screening process that uses resume review, a one-way video interview, and a short assessment, or whichever mix fits the role. Candidates respond on their own schedule, you review on yours, and every candidate is measured against the same criteria.

Truffle is candidate screening software built for small teams with no HR department. You paste the job description, and Truffle screens resumes, runs a one-way video interview, and adds an assessment if you want one, scoring every candidate against your criteria. AI surfaces the evidence. You make every call, nothing gets auto-rejected. For a 1-2 person LLC hiring its first employee, that turns a process that eats two weeks into one that runs in the background while you keep working, and the 30-second Candidate Shorts let you review a candidate in roughly the same time it takes to read a resume, with more signal.

Run a compliant background check

If you’re running background checks, the rules are stricter than most people realize.

• Federal Fair Credit Reporting Act (FCRA). You need a separate, standalone disclosure that you’re going to run a background check and written authorization from the candidate before you run it. If you decide not to move forward because of what the report shows, the process is two steps: send a pre-adverse action notice with a copy of the report and the “Summary of Your Rights Under the FCRA,” give the candidate a reasonable window (commonly treated as at least five business days) to dispute anything in it, then send the final adverse action notice if you’re still moving on.
• Ban-the-box laws. Many states and cities prohibit asking about criminal history before a conditional offer. Check your jurisdiction.
• Negligent hiring exposure. On the other side, hiring without checking when you should have can create employer liability if something goes wrong. Roles involving children, vulnerable adults, money handling, or driving carry more weight here.

Use a reputable background-check vendor (Checkr, Sterling, GoodHire) rather than doing it yourself. The compliance overhead is what you’re paying for.

Day-1 paperwork you actually have to file

The first day of employment triggers a short list of legally required documents. Miss them and you create real problems.

• Form I-9, Employment Eligibility Verification. Section 2 must be completed within three business days of the hire’s start date, and the employee’s own Section 1 is due by their first day of paid work. As of August 1, 2026, USCIS requires a version of the form showing the 05/31/2027 expiration date. Printings that carried the July 31, 2026 expiration are no longer valid, so check the date printed on your copy before you use it.
• Form W-4, Employee’s Withholding Certificate. Tells you how much federal income tax to withhold.
• State withholding form. Most states have their own equivalent of the W-4.
• State new-hire reporting. Federal law sets an outer limit of 20 days to report new hires to the state, but several states require it sooner (some in as little as 7 to 14 days), so check your state’s specific window.
• E-Verify, if your state requires it. E-Verify is voluntary at the federal level for most private employers, but a growing list of states mandate it, several regardless of employer size. Confirm your state’s rule before your first hire’s start date.
• Required posters. Federal and state law requires specific labor-law posters in any workspace. Easy to forget for remote-first teams; still required.
• Employee handbook. Not legally required in most states, but for a first hire it’s where your policies on PTO, conduct, and termination actually live. Write it before you need it, not after the first dispute.
• Direct deposit and benefits enrollment. Not legally required, but if you’re using payroll software, this is also day one.

Set up a checklist. Use it for every hire. The 14th hire is the one where someone forgets the I-9.

Onboard like you mean it

The first 90 days predict whether someone stays, and whether they perform. Loose onboarding is the most expensive cheap thing you can do.

• Day 1. Paperwork, system access, hardware, intro to the team, set first-week expectations clearly.
• Day 7. Manager check-in. What’s working, what’s confusing, what do they need.
• Day 30. Has the role matched the description? Are they on track to deliver what you hired them for? Adjust if not.
• Day 60 and Day 90. Performance review against the goals you set in the offer or first week.

A documented onboarding plan also matters for legal reasons. If you ever need to part ways during a probationary period, you’ll be glad you have written check-ins, written goals, and written feedback in the file. Keep that file, along with your payroll and tax records, for at least four years after you file the fourth quarter’s return for that year. That’s the IRS floor for employment tax recordkeeping.

Common LLC hiring mistakes that cost money

A few patterns I see repeatedly with first-time LLC employers.

• Treating an employee as a contractor to skip payroll. The IRS catches this. State labor departments catch this. Workers’ compensation auditors catch this. You will pay the back taxes plus penalties.
• Skipping the operating agreement update. Every dispute I’ve watched first-time LLCs hit traces back to an operating agreement that did not anticipate employees.
• No written employment agreement. Even if your state allows at-will employment without one, write the offer letter. Spell out role, comp, benefits, exempt status, IP assignment, and non-disclosure.
• DIY payroll. Possible. Painful. Pay $50/month for software.
• No 90-day check-in process. You will not know whether the hire is working out. You will defer the decision. The decision will get harder.

Frequently asked questions about adding an employee to an LLC

Do I need an EIN if I’m a single-member LLC adding my first employee?

Yes. Single-member LLCs that file taxes on Schedule C of a personal return often skip the EIN, but the moment you have an employee, you need one to run payroll. Apply free on the IRS website and you’ll have it immediately, though allow up to two weeks before it’s usable for electronic deposits.

Can my LLC hire me as an employee?

It depends. A single-member LLC taxed as a sole proprietorship cannot pay the owner as a W-2 employee. A single-member LLC that has elected S-corporation tax treatment can and often should. A multi-member LLC has more flexibility but the rules get specific fast.

If you do elect S-corp treatment, the IRS requires you to pay yourself a reasonable salary for the work you actually do before you take any additional money out as a distribution. There’s no set dollar threshold. The test is what an unrelated employer would pay someone else to do the same job, and the IRS has pursued owners who paid themselves too little specifically to shrink their payroll tax. Talk to a CPA before you set up payroll for yourself.

Can I hire my spouse or an adult child as an employee?

Yes, and plenty of first-time LLC employers do. The role still has to be real (actual work, actual pay, actual hours), and you still owe the same EIN, payroll tax, I-9, and W-4 steps as any other hire. Depending on how your LLC is taxed and who’s on payroll, there can be specific tax treatment for a spouse or a child under 18 on the family payroll, so this is worth a short conversation with a CPA before you set it up.

What’s the difference between a 1099 contractor and a W-2 employee for an LLC?

W-2 employees have taxes withheld, get unemployment and workers’ comp protection, and follow your direction. 1099 contractors handle their own taxes, set their own schedule, and use their own tools. The IRS classification test (behavioral control, financial control, type of relationship) determines which one applies. Calling someone a contractor doesn’t make them one.

Do I need workers’ compensation for one employee?

In nearly every state, yes, from the first hire. Texas is the major exception, and a handful of other states exempt very small employers on non-construction work. Get the policy in place before the start date.

How long do I have to file Form I-9 for a new employee?

Three business days from the start date for your part (Section 2). The employee has to complete their part (Section 1) by their first day of paid work. Federal requirement, no exceptions, and the penalties for missing it have gone up over time. Also double check the form itself: as of August 2026, only the edition showing the 05/31/2027 expiration date is valid, so an old copy sitting in your files might already be out of date.

Adding an employee to an LLC is not the hardest thing you’ll do this year. But it does have a long checklist, and skipping items has tail consequences that show up two years later. Get the legal plumbing right, write a position description that does double duty, and build a screening and onboarding process you can actually run, because the paperwork was never the part that determined whether the hire worked out.

Once the legal side is handled, see how Truffle screens your first hire. Paste the job description, screen resumes and run a one-way interview against your own criteria, and start with a 7-day free trial (30 credits, no card required).
