Health Insurance Expense

Health insurance expense is the cost an employer records for providing health coverage, such as medical, dental, vision and prescription drug benefits, to its employees and often their families during an accounting period. It usually consists of the employer's share of insurance premiums paid to an insurer, or, for a self-insured employer, the claims and administration costs of running its own plan. The portion of premiums paid by employees through payroll deductions is not part of the employer's expense.

Health coverage is one of the largest employee fringe benefits in the United States, where most working-age people get insurance through an employer. According to the KFF Employer Health Benefits Survey, average annual premiums for family coverage exceeded $25,000 in 2024, with employers paying roughly three quarters of the cost. Because of its size, health insurance expense is closely watched in budgeting and labor cost analysis.

Under accrual accounting, health insurance expense is recognized in the period in which coverage is provided, regardless of when premiums are paid. A typical monthly cycle runs as follows:

• When payroll is processed, employee contributions withheld from pay are credited to a liability, often called health insurance premiums payable.
• When the monthly premium invoice arrives, the employer records the full premium, debiting health insurance expense for its share, debiting the liability for the employees' share, and crediting cash or accounts payable for the total.
• If premiums are paid in advance for several months, the amount is first recorded as prepaid expenses and moved to expense month by month.
• If coverage has been provided but not yet billed at period end, the employer records an accrued liability.

For example, a company with 40 enrolled employees pays a total premium of $32,000 for January, of which employees contribute $6,400 through payroll deductions. The company debits health insurance expense for $25,600 and the employee withholding liability for $6,400, and credits cash for $32,000. On the income statement, the $25,600 appears within salaries and benefits or is spread across functions, with the share relating to factory workers included in manufacturing overhead and therefore in inventory cost.

Many larger employers self-insure, paying employees' medical claims directly rather than buying a fully insured policy, often with stop-loss insurance to cap very large claims. Their health insurance expense consists of claims paid, administration fees paid to a third-party administrator and stop-loss premiums. Because claims are usually submitted weeks or months after treatment, a self-insured employer must estimate and accrue claims that have been incurred but not reported (IBNR) at each period end. This estimate is commonly based on historical lag patterns. A company that typically sees claims of $400,000 a month and finds that about 1.5 months of claims are unreported at any time would carry an IBNR liability of around $600,000. Errors in this estimate can shift expense between periods noticeably.

In the United States, employer-paid health insurance premiums are generally deductible by the employer as a business expense and excluded from employees' taxable income under the Internal Revenue Code, a significant tax advantage compared with paying the same amount as wages. Employee contributions made through a cafeteria plan are also typically paid with pre-tax dollars, reducing taxable wages and therefore both income tax and payroll taxes. Under the Affordable Care Act, employers with 50 or more full-time employees, including equivalents, must offer affordable coverage meeting minimum standards to most full-time staff or risk a penalty, and must report coverage to the IRS. The cost of employer coverage also appears, for information, on employees' Form W-2.

Employers control health insurance expense by choosing plan designs with higher deductibles, offering health savings accounts, running wellness programs, changing the share employees pay and switching to self-insurance or level-funded plans. Each choice involves trade-offs between cost, risk and employee satisfaction. Analysts and budget planners often express the cost per employee per month, which makes trends easy to compare from year to year and against industry surveys. Like other insurance costs, it is also a component of the fully loaded labor rate used in pricing and project costing, alongside employer payroll taxes.
