Health Insurance for Startups: What to Offer at 1, 5, 20 and 50 Employees

• Employers need roughly 50 full-time and full-time equivalent employees before the federal employer mandate applies (HealthCare.gov, 2026).
• The average worker paid $1,440 for single coverage and $6,850 for family coverage in 2025, out of premiums of $9,325 and $26,993 (KFF Employer Health Benefits Survey, 2025).
• A QSEHRA can reimburse up to $6,450 for self-only coverage and $13,100 for family coverage in 2026 (IRS Rev. Proc. 2025-32, via Mercer).
• The small business health care tax credit is worth up to 50% of premiums for employers with fewer than 25 FTEs and average wages under $67,000 (IRS Form 8941 instructions, 2025).
• A Section 125 plan removes the 7.65% employer FICA tax on every pre-tax premium dollar (IRS Tax Topic 751, 2026).

Most startups do not think about health insurance until a good candidate asks about it. By then the founders are picking a plan under time pressure, with no HR person and a tight budget. This guide shows what you must do, what you can choose to do, and a simple order for adding benefits as the team grows.

Does a startup have to offer health insurance?

No. A startup is not required to offer health insurance unless it has at least 50 full-time and full-time equivalent employees. Employers below that line face no penalty for skipping coverage (HealthCare.gov, 2026).

The mandate counts full-time employees plus the hours of part-time staff converted to full-time equivalents, so a company with 40 people can cross 50 during a hiring surge. Plan ahead if you expect to grow past that number in the next year. Our guide to ICHRA requirements→ explains how the employer mandate interacts with an ICHRA.

Most startups offer coverage for a business reason. In 2025, 59% of firms with 10 to 199 workers offered health benefits, compared with 97% of firms with 200 or more workers (KFF Employer Health Benefits Survey, 2025). A candidate comparing offers often assumes a company at your size will have something.

What are the health insurance options for a startup?

A startup has four main choices: a small group health plan, an ICHRA, a QSEHRA and a stipend. A Section 125 cafeteria plan sits on top of any of them to lower tax.

How much does health insurance cost a startup?

The average annual premium in 2025 was $9,325 for single coverage and $26,993 for family coverage. Workers paid an average of $1,440 for single coverage and $6,850 for family coverage, which is 16% and 26% of the premium (KFF Employer Health Benefits Survey, 2025).

The employer pays the rest. For one employee on single coverage, that is about $7,885 a year at the national average. Your quote will differ by state, employee age and plan type. Treat these numbers as a budget check, not a quote.

Premiums are also rising. See the health insurance premium increase→ guide by state before you set a budget.

Which startups qualify for the small business health care tax credit?

A startup can qualify if it has fewer than 25 full-time equivalent employees and pays average annual wages below $67,000 per FTE. The credit is worth up to 50% of premiums for most employers and lasts two consecutive tax years (IRS Form 8941 instructions, 2025).

The employer must also pay a uniform share of at least 50% of each enrolled employee's premium, and generally buy through the Small Business Health Options Program, or SHOP (IRS Form 8941 instructions, 2025). The credit shrinks once wages pass $33,000 per FTE. Many early-stage companies with highly paid engineers will not qualify. Check before you count on it. Our tax credit guide→ has the full rules.

What is the best health insurance order as a startup grows?

Add benefits in steps, so cost grows with headcount. The order below works for most startups. It is a starting point, not a rule.

1. 1 to 3 employees: Use a QSEHRA or a stipend. It is simple and has no minimum enrollment.
2. 4 to 10 employees: Shop a small group plan and an ICHRA. Compare the true cost for your team, not only the monthly rate.
3. 11 to 30 employees: Offer a group plan with an employer share, and add a Section 125 plan so employees pay premiums before tax.
4. 30 to 50 employees: Watch your headcount. At 50 FTEs the employer mandate applies, so confirm the plan meets affordability and minimum value rules.

How does a Section 125 plan help a startup?

A Section 125 cafeteria plan lets employees pay their share of premiums before income and payroll tax. The company saves the 7.65% employer FICA tax on those dollars. FICA is the Social Security (6.2%) and Medicare (1.45%) payroll tax (IRS Tax Topic 751, 2026).

Here is a hypothetical example. A 5-person startup has employees who each contribute $400 a month toward premiums. That is $2,000 a month in pre-tax contributions, and the 7.65% employer share is $153 a month, or $1,836 a year. Employees also keep more take-home pay because they skip income tax and FICA on those dollars.

The plan must be in writing, and every participant must be an employee. Owners of more than 2% of an S corporation cannot take part as employees (IRS Publication 15-B, 2026). See the setup steps→ and the cost of a Section 125 plan→ for the details.

How do you pick a plan without an HR team?

Pick the plan by answering four questions in order. This keeps the decision short and keeps you from overbuying.

1. How many people are you covering in the next 12 months?
2. What can the company spend per employee per month?
3. Are employees in one state or several?
4. Do you want a plan the whole team shares, or an allowance each person spends their own way?

If you cannot answer the third question yet, an ICHRA or QSEHRA is more flexible. If the team is local and wants a familiar plan, a small group plan is simpler. Benecor Health helps employers set up the Section 125 layer and compare the options on the company's own numbers.
