Your share of the employer plan premium, taken each pay period — and if it runs through a Section 125 plan, taken before income tax and FICA.
The health insurance line on your stub is your share of the premium for the coverage you elected, divided across the pay periods in the plan year. Your employer pays the rest. Across private industry in March 2025, employers paid 80% of the premium for single coverage and 69% for family coverage, leaving employees with 20% and 31%, according to the Bureau of Labor Statistics. Nearly all employer plans run the employee share through a Section 125 cafeteria plan, and that matters more than most people realise. Publication 15-B lists accident and health benefits as exempt from income tax withholding, from Social Security and Medicare, and from FUTA. A 401(k) deferral escapes income tax only. A pre-tax medical premium escapes income tax and the 7.65% of FICA as well — one of the few common deductions that does both. That exclusion is also why the deduction is hard to change mid-year. A Section 125 election is generally locked for the plan year, and only a permitted change in status — marriage, divorce, birth, adoption, a spouse's coverage change, a loss of other coverage — reopens it. On the stub, look for MED, MEDICAL, MED PRE, S125 or CAF125 in the deductions block, with DEN and VIS on separate lines. Some employers print their own share as an informational line such as ER MED, which does not reduce your net pay. One number readers often chase: W-2 Box 12 code DD is the total cost of employer-sponsored coverage, employer share plus yours. It is informational, it is not taxable, and it is not what came out of your checks.
A deduction can be pre-tax, post-tax, voluntary, or required. Its label alone does not establish how it affects taxable wages, so check the plan document, employee election, payroll policy, and year-to-date amount.
When this term appears on a statement, read its label, current amount, year-to-date amount, pay-period context, and any adjacent rate or hours together. Resolve a mismatch with the original issuer or the cited authority rather than changing a record to force a preferred result.
Example
Semi-monthly, $2,000.00 gross, $150.00 medical premium through a Section 125 plan. Wages taxed: $2,000.00 − $150.00 = $1,850.00. Social Security: $1,850.00 × 6.2% = $114.70, instead of $124.00 on the full $2,000.00. Medicare: $1,850.00 × 1.45% = $26.83, instead of $29.00. FICA this check: $141.53 rather than $153.00 — $11.47 less. Federal income tax at 12% on the excluded $150.00: $18.00 less. So the $150.00 premium reduces take-home by about $120.53, not $150.00. A post-tax medical line would cost the full $150.00.
