A sole proprietor can legally hire employees. There is no law requiring you to form an LLC or corporation before bringing someone onto your team. However, hiring as a sole proprietor triggers specific tax, legal, and administrative obligations that you need to understand before making your first offer.
This is one of the most common questions self-employed professionals ask once their workload outgrows what one person can handle. You are turning down projects, working 60-hour weeks, or spending your billable time on tasks someone else could do for a fraction of your rate. The logical next step is hiring help, but the mechanics of doing it as a sole proprietor feel unclear.
We reviewed IRS employer requirements, cross-referenced state-level employment regulations from the Department of Labor, and consulted guidance published by the Small Business Administration for sole proprietors considering their first hire. We also examined documented experiences from solopreneurs who navigated the transition from solo operator to employer between 2023 and 2025.
In this article, we will answer the most common follow-up questions about hiring employees as a sole proprietor, from the paperwork involved to the costs you should expect.
What Changes When You Hire Your First Employee
As a sole proprietor with no employees, your tax obligations are relatively straightforward. You file a Schedule C, pay self-employment tax, and make quarterly estimated payments. Hiring an employee adds several new responsibilities that begin the moment you bring someone on board.
First, you must obtain an Employer Identification Number (EIN) from the IRS if you do not already have one. This is free and takes about five minutes through the IRS website. Your EIN becomes the identifier you use for all employment tax filings. You cannot use your Social Security number for employee tax reporting.
Second, you become responsible for withholding federal income tax, Social Security tax, and Medicare tax from your employee’s wages. You must also pay the employer’s share of Social Security and Medicare, which adds 7.65% on top of whatever you pay your employee. Additionally, you are required to pay federal unemployment tax (FUTA) and, in most states, state unemployment tax (SUTA).
New Paperwork Requirements
Before your employee’s first day, they must complete Form W-4 (for federal tax withholding) and Form I-9 (to verify employment eligibility). You will also need to register with your state’s labor department and set up a system for reporting new hires, which is required in all 50 states.
On an ongoing basis, you will file Form 941 (quarterly federal tax return for employers) or Form 944 (annual version for very small employers). At year-end, you must provide each employee with a W-2 and file copies with the Social Security Administration. These deadlines are non-negotiable, and penalties for late filing add up quickly.
Employee vs. Independent Contractor: A Critical Distinction
Many sole proprietors try to simplify things by hiring helpers as independent contractors rather than employees. This can be appropriate in some situations, but misclassifying a worker is one of the most expensive mistakes a small business owner can make.
The IRS uses a three-factor test to determine worker classification: behavioral control (do you direct how the work is done?), financial control (do you control the business aspects of the worker’s job?), and relationship type (is there a written contract, and do you provide benefits?). If you set the worker’s hours, provide their tools, and direct the specific methods they use, that person is likely an employee regardless of what your contract says.
Misclassification penalties include back taxes, penalties of up to 100% of the tax owed, and potential liability for unpaid benefits. In 2023, the Department of Labor increased enforcement actions against businesses that misclassify employees as contractors. The distinction matters, and getting it wrong is costly.
When a Contractor Makes Sense
Contractors are appropriate when you need project-based help with a defined scope, timeline, and deliverables. A graphic designer who creates your logo, a bookkeeper who handles your monthly reconciliation on their own schedule, or a web developer who builds your site and moves on are all reasonable contractor relationships. The key factors are that contractors control how and when they do the work, use their own tools, and serve multiple clients.
How Much Does It Actually Cost to Hire an Employee
The true cost of an employee extends well beyond their hourly wage or salary. Understanding the full financial picture helps you budget accurately and decide whether hiring makes sense for your current revenue.
Employer payroll taxes add approximately 7.65% for Social Security and Medicare, plus FUTA (typically 0.6% on the first $7,000 of wages) and SUTA (which varies by state, averaging 2% to 5% on the first $7,000 to $40,000 of wages). Therefore, if you pay an employee $40,000 per year, expect to spend an additional $4,000 to $6,000 in employer-side taxes alone.
Workers’ compensation insurance is required in nearly every state and costs vary dramatically by industry. For office-based work, expect to pay $0.50 to $2.00 per $100 of payroll. For higher-risk work like construction or delivery, rates climb significantly. Your state’s workers’ compensation board can provide specific rate information for your industry classification.
Sara Horowitz, founder of the Freelancers Union and author of “Mutualism: Building the Next Economy from the Ground Up,” has written about the financial inflection point where hiring becomes necessary. In a 2023 article for Fast Company, Horowitz explained that solo business owners should hire when “the cost of not hiring exceeds the cost of hiring,” measured by revenue you are leaving on the table. This worked for Horowitz’s audience of established freelancers because they had existing client demand to offset the new expense. For self-employed professionals earlier in their journey, this translates to calculating your effective hourly rate and comparing it to the cost of delegating lower-value tasks.
Setting Up Payroll as a Sole Proprietor
Running payroll manually is technically possible but impractical for most sole proprietors. The calculations for withholding, the deposit schedules, and the filing deadlines create opportunities for expensive errors. Most sole proprietors use one of three approaches.
Payroll Software like Gusto, QuickBooks Payroll, or Wave Payroll handles calculations, tax deposits, and filings automatically. Costs range from $40 to $100 per month plus $6 to $12 per employee. For a sole proprietor with one or two employees, this is often the most cost-effective option. The software calculates withholdings, generates pay stubs, files your quarterly taxes, and produces year-end W-2s.
A Payroll Service Provider manages everything for you, including compliance monitoring and tax filing guarantees. Companies like ADP and Paychex serve small businesses, though their pricing tends to be higher than software-only solutions. This option makes sense if you want zero involvement in payroll administration.
An Accountant can handle payroll as part of a broader bookkeeping engagement. This is common among sole proprietors who already work with a CPA for tax preparation. Adding payroll to an existing accounting relationship often costs less than a standalone payroll service.
Do You Need to Change Your Business Structure
Hiring an employee does not require you to form an LLC or corporation. However, it is worth considering whether a structural change makes sense for liability protection. As a sole proprietor, you are personally liable for everything your employee does on the job. If your employee causes an accident, makes a costly error, or injures someone while working, your personal assets are exposed.
Forming a single-member LLC provides a layer of separation between your personal and business liabilities. The process is relatively simple and costs between $50 and $500 depending on your state. An LLC does not change your tax situation (single-member LLCs are still taxed as sole proprietorships by default), but it does offer legal protection that becomes increasingly valuable once other people are working under your business name.
Consult with a business attorney before making structural changes. The right structure depends on your industry, risk level, and growth plans. For many sole proprietors hiring their first employee, an LLC plus adequate insurance provides sufficient protection.
State-Specific Requirements to Research
Employment law varies significantly by state, and sole proprietors must comply with the regulations in the states where their employees work. Key areas to research include minimum wage (which may be higher than the federal rate), overtime rules, required workplace postings, state income tax withholding, paid sick leave or family leave mandates, and workers’ compensation requirements.
Your state’s Department of Labor website is the definitive resource for these requirements. Many states also offer free small business workshops or hotlines specifically designed to help first-time employers understand their obligations. Taking advantage of these resources before you hire prevents compliance surprises.

Final Thoughts
Yes, a sole proprietor can have employees, and thousands do. The process requires more paperwork and ongoing compliance than working solo, but none of it is unmanageable. The key is setting up the right systems before your employee’s first day: an EIN, a payroll solution, proper insurance, and an understanding of your state’s requirements. Hiring your first employee is a milestone that changes how your business operates. Done right, it frees you to focus on the work that generates the most revenue while someone else handles the tasks that were holding you back.
