“ER” on your paycheck stands for “employer,” not emergency room. The line labeled something like “ER cost medical” or “ER health” shows how much your employer pays toward your health insurance premium each pay period. This amount isn’t deducted from your pay. It appears on your pay stub for transparency, so you can see the full cost of your health coverage.
What “ER” and “EE” Mean on a Pay Stub
Payroll systems use two-letter abbreviations to save space. “ER” means employer. “EE” means employee. So when you see “ER Medical” or “ER Health,” that’s the employer’s share of your health insurance premium. When you see “EE Medical” or “PRETAX PREM-MED,” that’s your share, the amount actually subtracted from your paycheck.
You might also see these abbreviations attached to other benefits:
- ER HSA: Your employer’s contribution to your health savings account
- ER FSA: Your employer’s contribution to a flexible spending account
- EE-EMP OPT LIFE: Your employee-paid optional life insurance premium
- Fed MED/ER: This is different. It refers to your employer’s Medicare tax contribution, not your medical insurance
The key distinction: ER lines show what your employer contributes on your behalf. EE lines show what comes out of your earnings. Only the EE amounts reduce your take-home pay.
How Much Employers Typically Contribute
Employers cover the majority of health insurance costs for most workers. According to the Kaiser Family Foundation’s 2024 survey, the average total premium for employer-sponsored health insurance is $8,951 per year for single coverage and $25,572 for family coverage. Those are large numbers, and your employer picks up most of the tab.
For single coverage, the average worker pays about $1,368 per year (roughly $114 per month), while the employer pays the remaining $7,583. For family coverage, workers pay an average of $6,296 per year (about $525 per month), with the employer covering around $19,276. That means employers pay roughly 84% of the premium for individual plans and 75% for family plans.
If the ER medical amount on your pay stub seems surprisingly high, this is why. Your employer is often spending $300 to $800 per pay period on your health coverage alone, depending on whether you have single or family coverage and how often you’re paid. Multiply the per-paycheck figure by your number of pay periods (typically 26 for biweekly or 24 for semimonthly) to get the annual employer contribution.
Why It Shows Up on Your Pay Stub
You might wonder why your employer bothers listing a cost that doesn’t affect your take-home pay. There are two main reasons.
First, transparency. Your employer wants you to see the full value of your compensation package, not just your salary. That ER medical line is real money being spent on your behalf, and it’s part of what your employer considers your total compensation.
Second, federal reporting. The IRS requires most employers to report the total cost of employer-sponsored health coverage on your W-2 form at the end of the year, in Box 12 using Code DD. This total includes both the employer’s share and your share. Showing the breakdown on each pay stub makes it easier for payroll to calculate that annual figure.
Does It Count as Taxable Income?
No. The ER medical cost on your pay stub is not taxable income. The IRS has been clear on this point: the reporting requirement exists purely for informational purposes. Your employer’s contribution to your health insurance remains excluded from your taxable income, just as it always has been. Seeing a large dollar amount on your pay stub next to “ER Medical” does not mean you owe taxes on it.
Your own premium contributions (the EE lines) are also typically pre-tax, meaning they’re deducted from your pay before income taxes are calculated. This is standard when your employer offers coverage through what’s called a Section 125 cafeteria plan, which most do. You can confirm this by checking whether your deduction is labeled “PRETAX” on your stub.
How to Read Your Full Health Cost
To understand the complete picture of what your health insurance costs, add together the ER and EE amounts for medical coverage on a single pay stub, then multiply by the number of pay periods in your year. That gives you the total annual premium for your plan. Compare this to your plan’s benefits, deductible, and out-of-pocket maximum to evaluate whether your coverage is a good deal relative to national averages.
If you have a high-deductible health plan, your employer’s total contribution may include both the premium and an HSA deposit. The 2024 average employer contribution for workers in high-deductible plans with health reimbursement arrangements is $7,879 for single coverage and $20,990 for family coverage. Look for separate ER HSA or ER HRA lines on your stub to see if your employer is contributing to those accounts on top of the premium.
Keep your final pay stub of the year or your W-2 for reference. Box 12, Code DD on your W-2 will show the combined total of employer and employee health coverage costs for the full year, giving you one clean number to work with during tax season or when comparing job offers.
