On a pay stub, benefits enrollment form, or tax summary, EE means employee and ER means employer. Wherever a cost or contribution is split between you and the company, EE is your share and ER is the company’s. That is what EE and ER mean in payroll, and knowing which column applies tells you exactly what leaves your paycheck, what your employer pays on top, and where to look when a number seems off.
What the Labels Actually Point To
EE labels anything tied to you as the worker. “EE Health” or “EE Dental” on a pay stub is the amount deducted from your paycheck for that benefit. An “EE contribution” on a 401(k) statement is money you chose to defer from your own pay.
ER labels anything tied to the company. An “ER contribution” or “ER match” is money the employer puts in on your behalf. It never appears as a deduction because it never touched your paycheck. The reason the distinction matters: EE amounts reduce your take-home pay directly, while ER amounts add value to your total compensation without showing up as a subtraction.
How EE and ER Split FICA Taxes
The most visible EE/ER split is FICA, the combination of Social Security and Medicare taxes. The law sets identical rates for each side. The employee pays 6.2% of gross wages toward Social Security and 1.45% toward Medicare, and the employer pays the same percentages from its own funds.1Office of the Law Revision Counsel. 26 U.S. Code 3101 – Rate of Tax2Office of the Law Revision Counsel. 26 U.S. Code 3111 – Rate of Tax The combined FICA cost of employing someone is 15.3%, but you only see your half on the pay stub.
The Social Security Wage Cap
The 6.2% Social Security rate applies only up to an annual earnings ceiling. For 2026, that cap is $184,500.3Social Security Administration. Contribution and Benefit Base Once your year-to-date wages reach that number, Social Security withholding stops for both you and your employer, and your net pay bumps up slightly in the pay period that crosses the threshold. Medicare has no cap. The 1.45% keeps coming out of every dollar you earn.
The Additional Medicare Tax
Workers earning above $200,000 in a calendar year owe an extra 0.9% Medicare surtax on wages above that threshold.4Internal Revenue Service. Topic No. 560, Additional Medicare Tax Your employer must begin withholding it once your pay crosses $200,000, regardless of filing status. Your final liability depends on how you file: married couples filing jointly owe it on combined wages above $250,000, and those filing separately hit the threshold at $125,000. This one is purely an EE cost. The employer does not match it.
How EE and ER Apply to Benefits
The same EE and ER labels appear on benefits enrollment summaries and in the deductions section of your pay stub. EE is what comes out of your paycheck. ER is what the company pays on top. Together they represent the full cost of the benefit.
Health Insurance Premiums
Most employers cover a substantial share of health premiums. A benefits summary might show a total monthly premium of $800 for an individual plan, with the ER paying $600 and the EE paying $200. Only that $200 appears as a deduction on your paycheck. For employers with 50 or more full-time workers, the Affordable Care Act limits how much the EE share can cost relative to the worker’s income. For the 2026 plan year, coverage is considered affordable if the employee’s required contribution does not exceed 9.96% of household income.
Retirement Contributions
Retirement plans are where the EE/ER labels get the most attention. The EE contribution is what you elect to defer from each paycheck into your 401(k). For 2026, the annual EE limit is $24,500, with an additional $8,000 in catch-up contributions allowed at age 50 and older.5Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026 The ER contribution is the company match or profit-sharing amount. A common structure is 50 cents matched for every dollar you put in, up to 6% of your salary. Because the match is contingent on your own contributions, the EE/ER split tells you how much to save to capture everything the company offers.
Pre-Tax and After-Tax EE Deductions
Many EE benefit deductions run through a Section 125 cafeteria plan, meaning they come out of your paycheck before federal income tax is calculated. Health insurance premiums, dependent care expenses, and health savings account contributions are common examples.6Internal Revenue Service. FAQs for Government Entities Regarding Cafeteria Plans A $200 pre-tax health premium doesn’t just reduce your take-home pay by $200; it also lowers the income on which you owe federal and usually state taxes. Other EE deductions are after-tax, such as Roth 401(k) contributions or some supplemental insurance products. Your pay stub should label each one, and HR can confirm which reduce your taxable income if the label is unclear.
ER Costs You Never See on Your Stub
Some employer costs never appear on your pay stub at all because there’s no matching EE side. The Federal Unemployment Tax Act imposes a 6% tax on the first $7,000 of each worker’s annual wages, and it falls entirely on the employer.7Office of the Law Revision Counsel. 26 U.S. Code 3301 – Rate of Tax8Office of the Law Revision Counsel. 26 U.S. Code 3306 – Definitions Employers who pay state unemployment taxes on time receive a credit of up to 5.4%, dropping the effective federal rate to 0.6%.9Internal Revenue Service. FUTA Credit Reduction State unemployment insurance works similarly, funded by ER contributions with taxable wage bases that vary widely by state. A few states also require EE contributions to state disability or paid family leave programs, which show up on pay stubs with labels like “SDI” or “PFML.”
When There Is No ER Side
If you’re self-employed, the EE/ER distinction collapses onto you. Freelancers, sole proprietors, and gig workers pay the full 15.3% self-employment tax: 12.4% for Social Security and 2.9% for Medicare.10Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) That’s the employee half and the employer half combined into a single payment. The tax code lets you deduct the employer-equivalent portion when calculating adjusted gross income, which lowers your income tax but does not reduce the self-employment tax itself. Independent contractors have no ER at all: no one withholds their FICA, no one matches it, and no one pays unemployment tax on their behalf.
Where EE and ER Show Up on Your W-2
Your W-2 is the annual record of what came out of your pay. Box 2 shows federal income tax withheld. Box 4 shows Social Security tax (the EE 6.2%). Box 6 shows Medicare tax (the EE 1.45%). Employers must deliver the form by January 31.
Box 12 uses lettered codes for certain benefit amounts. Code D reports what you contributed to a 401(k). Code DD reports the combined cost of employer-sponsored health coverage, both EE and ER portions together, and it’s informational rather than taxable.11Internal Revenue Service. Form W-2 Reporting of Employer-Sponsored Health Coverage The Code DD figure is often a surprise, because most workers only see the EE premium deducted each pay period and never the full cost of the coverage. If you work for a company with 50 or more full-time employees, you’ll also receive Form 1095-C, which documents what health coverage the ER offered, what it cost the EE, and whether you enrolled.12Internal Revenue Service.

Once you know that EE is your share and ER is the company’s, every line on the pay stub and every code on the W-2 sorts into one of two columns. The paycheck deduction is the EE amount. The line you never see, but that still counts toward your total compensation, is the ER amount.
