Employers get several tax breaks for offering health insurance: premiums paid for employees are deductible as an ordinary business expense, amounts routed through a pre-tax plan escape payroll taxes on both sides, and small employers can claim a credit worth up to 50% of the premiums they pay (35% for tax-exempt organizations). Employer contributions to HSAs and FSAs get the same favorable treatment. The catch is that owner coverage in pass-through entities follows a different path, and employers with 50 or more full-time employees face penalties if they don’t offer coverage at all.
Premiums Are Deductible as a Business Expense
The core break is the simplest one. Health insurance premiums an employer pays for its employees are deductible as an ordinary and necessary business expense under the general rule for trade or business deductions.1Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses Every dollar reduces taxable income dollar-for-dollar.
A C-corporation deducts premiums against gross revenue on the corporate return with no special form or election. S-corporations, partnerships, and sole proprietorships deduct the employer share of group health plan costs for their rank-and-file employees the same way. Entity type doesn’t change the answer for common-law employees.
On the employee side, the same premium dollars are excluded from gross income entirely.2Office of the Law Revision Counsel. 26 USC 106 – Contributions by Employer to Accident and Health Plans When a business pays $8,000 toward an employee’s coverage, that $8,000 never shows up as taxable wages, and neither side owes income or payroll tax on it. That is the reason routing compensation through health benefits costs less than paying the equivalent in cash.
Owner Coverage Is Different
Owners of pass-through entities generally cannot receive tax-free health benefits the way their employees do. Instead, self-employed individuals take a separate deduction on their personal return for health insurance costs, which reduces adjusted gross income.1Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses Two limits apply: the deduction can’t exceed the owner’s earned income from the business that established the plan, and it isn’t available for any month the owner was eligible for a subsidized plan through another employer or a spouse’s employer.
Payroll Tax Savings Through a Section 125 Plan
The business deduction is only part of the picture. Employers who route employee premium contributions through a Section 125 cafeteria plan avoid payroll taxes on those amounts as well. Under a salary reduction agreement, the employee’s share of premiums is paid with pre-tax dollars and is not treated as wages for federal income tax, Social Security, or Medicare purposes.3Office of the Law Revision Counsel. 26 USC 125 – Cafeteria Plans4Internal Revenue Service. FAQs for Government Entities Regarding Cafeteria Plans
The employer’s share of FICA is a matching 6.2% Social Security tax and 1.45% Medicare tax, a combined 7.65% on wages.5Internal Revenue Service. Topic No. 751 – Social Security and Medicare Withholding Rates When $5,000 in premiums flows through a Section 125 plan instead of being paid from after-tax wages, the employer avoids $382.50 in FICA on that amount per employee. Federal unemployment tax drops too. The standard FUTA rate is 0.6% on the first $7,000 of each employee’s wages, and Section 125 salary reductions shrink that taxable base as well.6Employment and Training Administration. FUTA Credit Reductions
Setting up the plan requires a formal written document describing the benefits offered and the election rules. Section 125 plans also must pass nondiscrimination tests. If a plan fails, highly compensated employees lose pre-tax treatment on their contributions; rank-and-file employees keep theirs. Most third-party administrators handle the testing as part of their standard service.
HSA and FSA Contributions
Employer contributions to a Health Savings Account are excluded from the employee’s gross income and exempt from FICA and FUTA, and the employer still deducts the contribution as a business expense.7Internal Revenue Service. Publication 15-B, Employer’s Tax Guide to Fringe Benefits A $1,000 HSA contribution costs the employer exactly $1,000. A $1,000 raise costs an extra $76.50 in FICA before the employee loses another chunk to income tax.
HSAs must be paired with a qualifying High Deductible Health Plan. For 2026, the combined contribution limit (employer plus employee) is $4,400 for self-only coverage and $8,750 for family coverage, with a $1,000 catch-up for employees age 55 or older. The HDHP must have a minimum annual deductible of $1,700 for individual coverage or $3,400 for family coverage, and out-of-pocket costs cannot exceed $8,500 for individuals or $17,000 for families.8Internal Revenue Service. Revenue Procedure 2025-19
Health Flexible Spending Arrangements deliver a similar payroll tax benefit with tighter rules. Employer contributions to a health FSA are excluded from wages, saving the same 7.65% FICA. For 2026, employees can contribute up to $3,400 through salary reduction.7Internal Revenue Service. Publication 15-B, Employer’s Tax Guide to Fringe Benefits Unspent funds are generally forfeited at the end of the plan year. Employers can soften this in one of two ways, but not both: a carryover of up to $680 of unused funds into the following year for 2026 plan years,9Internal Revenue Service. Publication 969 – Health Savings Accounts and Other Tax-Favored Health Plans or a grace period of up to two months and fifteen days after the plan year ends during which employees can still spend the previous year’s balance.10Internal Revenue Service. Notice 2005-42
The Small Business Health Care Tax Credit
Small employers get a break that goes beyond a deduction. The Small Business Health Care Tax Credit reduces the tax owed dollar for dollar, up to 50% of the premiums an employer pays for employee coverage (35% for tax-exempt organizations).11Internal Revenue Service. Small Business Health Care Tax Credit and the SHOP Marketplace
Qualifying means meeting all of these:
- Fewer than 25 full-time equivalent employees. FTEs are total hours worked by all employees divided by 2,080.
- Average annual wages below an inflation-adjusted threshold (approximately $34,100 for 2026).
- The employer pays at least 50% of the premium cost for employee-only coverage.
- Coverage is purchased through the Small Business Health Options Program Marketplace.12HealthCare.gov. The Small Business Health Care Tax Credit
The credit begins phasing out above 10 FTEs or once average wages exceed the inflation-adjusted floor, and it drops to zero at 25 FTEs or the wage ceiling. It is only available for two consecutive tax years. After that window closes, the employer keeps the standard deduction and payroll tax savings but loses the credit itself.11Internal Revenue Service. Small Business Health Care Tax Credit and the SHOP Marketplace
QSEHRAs for Small Employers Without a Group Plan
Employers with fewer than 50 full-time employees who don’t offer a group health plan can use a Qualified Small Employer Health Reimbursement Arrangement. The employer reimburses employees for individual health insurance premiums and medical expenses up to a set annual limit. The reimbursements are excluded from employees’ income and deductible by the employer as a business expense.
For 2026, the maximum annual QSEHRA reimbursement is $6,450 for employees with self-only coverage and $13,100 for family coverage.13Internal Revenue Service. Revenue Procedure 2025-32 Employees must have minimum essential coverage to receive tax-free reimbursements, and the reimbursed amounts may reduce any premium tax credit they claim on the marketplace.
The Flip Side: Penalties for Large Employers That Don’t Offer Coverage
Employers with 50 or more full-time employees, including full-time equivalents, are classified as Applicable Large Employers and face penalties if they don’t offer affordable, minimum-value health coverage.14Internal Revenue Service. Determining if an Employer Is an Applicable Large Employer A full-time employee for this purpose works at least 30 hours per week or 130 hours per month.
Two separate penalties can apply:15Office of the Law Revision Counsel. 26 USC 4980H – Shared Responsibility for Employers Regarding Health Coverage
- If an ALE fails to offer minimum essential coverage to substantially all full-time employees and at least one employee receives a subsidized marketplace plan, the penalty is based on the total full-time workforce minus 30 employees. For 2026, this works out to $3,340 per full-time employee (after the 30-employee reduction) on an annualized basis.
- If the employer offers coverage but it doesn’t meet affordability or minimum-value standards and an employee receives a marketplace subsidy as a result, the penalty is $5,010 per affected employee for 2026.
Both amounts are inflation-adjusted annually. The first hits harder because it applies across the entire workforce (minus 30); the second is limited to the employees who actually received subsidized marketplace coverage.
