Payroll Deductions For Health Coverage Become Plan Money Quickly

When an employer withholds an employee’s share of health premiums, the money is treated as plan assets. Here is the timing rule, its limits and the open points.

Where Things Stand.

When an employee pays toward group health coverage, or has the cost withheld from wages, ERISA treats that money as plan assets. The Department of Labor’s regulation, 29 CFR 2510.3-102, says the money becomes a plan asset on the earliest date it can reasonably be separated from the employer’s general assets. The point of the rule is protective: plan assets must be used only to provide benefits and pay reasonable plan expenses, and they may never benefit the employer (ERISA section 403(c)(1), 29 U.S.C. 1103(c)(1)).

The regulation also sets ceilings. For an employee welfare benefit plan, which includes a group health plan, the date cannot be later than 90 days after the employer receives the amount or, for wage withholding, 90 days after it would otherwise have been payable to the employee in cash. That ceiling is not a target. The standard is as soon as the money can reasonably be separated, and the 90 days is the outer edge.

Separately, a safe harbor treats a deposit as timely if it is made by the seventh business day after the employer receives the amount, but only for plans with fewer than 100 participants at the start of the plan year. That safe harbor turns on plan size, not on whether the plan is a pension or a health plan, and it is optional. The tighter pension-plan limit, the 15th business day of the following month, does not apply to health plans.

Two practical points matter more than the regulation for most employers. A carrier contract usually sets a premium due date well inside 90 days, so the contract tends to be the tighter clock. And the Department of Labor has a long-standing, narrow enforcement position for cafeteria plans that is easy to misread, which we cover on its own page.

What Is Settled And What Is Not.

Settled by the text of the regulation: the plan-asset definition, the 90-day welfare plan ceiling, the 7-business-day safe harbor for plans under 100 participants, and the 15th-business-day rule for pension plans.

Less settled: Technical Release 92-01. The release was written to expire at the end of 1993 or when final regulations arrived, and later Federal Register documents still describe it as the department’s position. We could not confirm from the Department’s own page whether it has been formally reissued, so we treat it as an old enforcement policy, not as law.

Also worth knowing: the 2025 restatement of the Voluntary Fiduciary Correction Program added a self-correction option for late contributions, but only for pension plans. A late health plan contribution goes through the application process.
