Small Business Health Insurance for One Employee Explained
The term small business health insurance one employee describes group health coverage that an owner buys for a team of one, and often for themselves too. Yes, you can usually offer it, and no, you are not required to. Whether you qualify depends mostly on one thing: whether your worker is a true employee on your payroll and not a contractor, your spouse, or you.
Most group insurance was built for companies with many workers, so a team of one sits in a gray area. Some carriers accept an owner plus one employee as a group of two. Government marketplaces, reimbursement arrangements and private brokers each handle the case differently. This article explains who counts as your employee, which plan options exist, what coverage costs, how the small business tax credit works, and how to set everything up.
At Golden Health and Life Agency, we help business owners compare group plans across a network of over 300 carriers. Use this guide to decide whether coverage makes sense for you, then check the details with a licensed broker for your state.
Why one-employee group coverage matters
Group coverage for a single worker matters because it can lower your taxes, help you keep someone who is hard to replace, and cost you no penalty if you decide against it. It is a choice, not an obligation, so the real question is whether the benefit is worth the premium.
You are not required to offer it
Only applicable large employers, meaning those with 50 or more full-time equivalent employees, must offer coverage under the Affordable Care Act or risk a payment to the IRS. With one employee, nothing legally forces you to buy a plan.
You also have room to design the offer. You can cover your employee and skip yourself if you have other coverage, such as a spouse's plan or Medicare. What you generally cannot do is set eligibility rules based on an individual's health. Rules by class, such as full-time versus part-time, are fine.
What it does for your business
A group plan changes your position as an employer in several concrete ways:
Tax savings: premiums you pay are generally deductible as a business expense, and you may qualify for a federal credit of up to 50% of what you contribute.
Competitive hiring: a larger employer can offer coverage, so you need to as well if you want to keep a skilled worker.
No health screening: small group plans cannot deny coverage or raise your price because of anyone's medical history.
Year-round purchase: small group coverage can generally be bought in any month, not only during an open enrollment window.
What your employee does without it
If you do not offer a plan, your worker can shop on the individual Marketplace. Depending on household income, they may get premium tax credits there. That route is real, but it leaves them with open enrollment deadlines and no help from you with the cost.
Offering group coverage to one employee is optional, but it is often the cheapest benefit you can give once taxes are counted.
Who counts as your one employee
Your worker counts when you control how and when the work is done, you pay wages through payroll with a W-2, and the person is neither you nor your spouse. Carriers and the IRS both look at these facts, not at the job title.
The common-law employee test
The IRS uses a common-law test that weighs behavioral control, financial control, and the nature of the relationship. If you set the schedule, supply the tools, and direct the method, you probably have an employee. Withholding payroll taxes is the clearest sign.
Hours matter too. Under the ACA, full-time means 30 or more hours a week. Carriers set their own minimums for plan eligibility, so confirm the hours threshold before you apply.
Who does not count
Several people are easy to mistake for employees. A business whose only other worker is a spouse generally cannot buy a small group plan on that basis.
The owner, including a sole proprietor or partner
Your spouse, even when they work in the business full time
1099 contractors, because you do not control how they work
Certain family members and 2% S corporation shareholders, who are excluded when computing the small business tax credit
No W-2 employee other than you and your spouse means no small group plan, however many people help in the business.
Sole proprietors and single-member LLCs with no staff
If you are self-employed with no employees, you buy individual coverage. A single-member LLC owner can usually pay premiums personally and claim the self-employed health insurance deduction, provided they meet the IRS conditions. If you run an S corporation, owner premiums run through payroll, so have your tax professional set it up.
Plan options for a business with one employee
A business with one employee has five realistic routes: a small group plan through SHOP or directly from a carrier, a QSEHRA, an ICHRA, or a PEO. They differ in who owns the policy, how much risk you carry, and what paperwork you take on.
Five ways to cover one employee
Option | How it works | Best for | Watch for |
|---|---|---|---|
SHOP plan | Small Business Health Options Program, for employers with generally 1 to 50 employees | Owners who want the tax credit | Your state may run its own exchange |
Small group plan from a carrier | You pick a plan and set your contribution | Owners who want the broadest plan choice | Some carriers require two people in the group |
QSEHRA | You reimburse your employee tax-free for premiums and medical costs, within annual limits | Owners who want a fixed budget | Employer cannot also offer a group plan |
ICHRA | You set a monthly allowance toward an individual plan the employee picks | Owners who want flexibility | An affordable offer can affect the employee's Marketplace tax credits |
PEO | A co-employment arrangement that gives access to the PEO's group plans | Owners who also want HR help | Many PEOs set minimum headcounts |
Plan design matters as much as the route. A high-deductible plan paired with a Health Savings Account lowers the premium, and you can fund the HSA yourself. That suits a healthy employee who rarely uses care, but it shifts early costs to them.
Small business health insurance in California
California runs its own marketplace for employers, Covered California for Small Business, which serves businesses with 1 to 100 employees. You choose which coverage tiers to offer, from one up to all four of Bronze, Silver, Gold and Platinum, and you can add dental. You decide how much to contribute, receive one monthly bill, and enrollment runs year-round.
The federal tax credit of up to 50% of your contributions is available through that program for eligible employers, and eligibility is determined by the IRS. If you have no W-2 employees, individual coverage through Covered California is the better fit. Other states run similar exchanges or default to the federal SHOP, so check yours before you buy.
Which route is best depends less on the plan and more on whether you want the tax credit and a fixed or flexible budget.
What it costs and how the tax credit works
Expect group coverage for one employee to cost in the range of $9,300 a year, or about $775 a month, as a rough national benchmark for single coverage, based on KFF's 2025 Employer Health Benefits Survey. Your own quote will differ, and the credit can cut your net cost substantially.
What drives the premium
Small group premiums follow ACA rating rules, which limit what carriers can consider. The factors that move your quote are:
Age of the covered person, with older people costing more
Geographic rating area, which is why the same plan costs different amounts in different regions
Plan tier and type, such as Bronze versus Gold, or HMO versus PPO
Tobacco use, where your state allows it
Carrier and network, since broader networks cost more
Health history is not on the list. Your employee's medical conditions cannot raise the price.
A worked example with the tax credit
Assume a hypothetical employee-only premium of $600 a month. The table shows what you would pay at three contribution levels, and the most the credit could return at 50% of your contribution.
Employer pays | Your monthly cost | Your annual cost | Maximum credit | Net annual cost |
|---|---|---|---|---|
50% | $300 | $3,600 | $1,800 | $1,800 |
75% | $450 | $5,400 | $2,700 | $2,700 |
100% | $600 | $7,200 | $3,600 | $3,600 |
These figures ignore the business deduction, and the credit is also capped at the average premium in your area, so an expensive plan may not earn the full 50%. Your tax professional can confirm the actual number.
Who qualifies for the credit
The credit is for employers with fewer than 25 full-time equivalent employees and average annual wages below an inflation-adjusted IRS limit. You must pay at least 50% of the employee-only premium and generally buy through SHOP. The credit shrinks as average wages rise, so it is largest when your employee earns a lower wage.
You can claim it for two consecutive tax years, using IRS Form 8941. Healthcare.gov explains the rules and provides an FTE calculator.
The credit makes the 50% contribution minimum the best-value starting point, because it cuts your net cost in half before deductions.
How to set up coverage, step by step
You can set up a plan in a few weeks if your documents are ready. The order below keeps you from buying a plan you cannot get approved or from missing the credit.
Seven steps from decision to coverage
Confirm your employee qualifies as a W-2 common-law employee who is not you or your spouse.
Set your budget and contribution, remembering that the tax credit requires at least 50% of the employee-only premium.
Choose your route: SHOP, a direct small group plan, an HRA, or a PEO.
Get quotes for several carriers and plan tiers in your rating area.
Check networks, including your employee's doctors and prescriptions.
Submit the employer application and your employee's enrollment form.
Review at renewal, since premiums and rules change each year.
What carriers ask for
Expect to provide proof that the business and the employee are real. Gather these first:
Business name, address, and employer identification number
Recent payroll records or quarterly wage filings showing the employee
Business license or articles of incorporation
Employee's age, ZIP code, and any dependents to be covered
Some carriers also ask for proof of other coverage if the owner waives the plan. A waiting period before coverage starts is allowed, but the ACA caps it at 90 days.
Timing and broker help
Small group coverage can generally start on the first of any month, so there is no need to wait for a window. A licensed broker costs you nothing extra in most cases and can compare carriers side by side. Golden Health and Life Agency offers a one-hour health consultation where we review your situation and match you with carriers from our network of over 300.
Start with the employee check, because every other decision, from the plan to the tax credit, depends on it.
Getting started with one employee
You can offer small business health insurance for one employee when that person is a W-2 worker who is not you or your spouse. You choose among SHOP, a small group plan, a reimbursement arrangement or a PEO. At a $600 monthly premium and a 50% contribution, the tax credit can bring your net cost down to roughly $1,800 a year before deductions.
The rules vary by state and carrier, so the quickest way forward is to talk to a broker who can check them for your situation. If you want help comparing options, contact Golden Health and Life Agency and we will walk you through plans, costs and the next steps.
