Why are Social Security and Medicare taken out of a teen summer job paycheck? Usually because age does not exempt regular W-2 work from FICA. Here is what those lines mean, when they normally apply, when they might not, and a real $2,800 summer-job example.

Quick Summary
- Social Security and Medicare usually come out of a teen summer job paycheck because most regular W-2 jobs are subject to 7.65% FICA
- On a sample summer job paying $2,800 total, FICA adds up to about $214.20
- That breaks into about $173.60 for Social Security and $40.60 for Medicare
- A teen in Texas may only see federal taxes and FICA, while a similar teen in California may also see state withholding
A lot of teen workers assume something is wrong when they see Social Security and Medicare on a first paycheck. The surprise makes sense, but in most cases the employer did exactly what payroll rules require.
Age by itself does not make a paycheck exempt from FICA. If a teen works a normal W-2 job for a private employer, Social Security and Medicare usually come out just like they do for adult workers.
This is why a teen can earn only a few hundred dollars a week and still see those lines on the pay stub. The question is usually not “Why am I paying this?” but “Is this a normal FICA job?”
Why FICA comes out of a teen paycheck
Social Security and Medicare come out because they are payroll taxes tied to covered wages, not to age. A regular employee job usually triggers FICA whether the worker is 16, 26, or 56.
That catches a lot of teens off guard because income tax and FICA are different systems. A teen might owe little or no federal income tax for the full year, but still owe Social Security and Medicare on wages earned during the summer.
📊 Key Number
For most employees, the worker share of FICA is 7.65%: 6.2% for Social Security plus 1.45% for Medicare.
| Paycheck line | Typical rate | What it means |
|---|---|---|
| Social Security | 6.2% | Payroll tax on covered wages |
| Medicare | 1.45% | Payroll tax on covered wages |
| Total employee FICA | 7.65% | Usually applies even if the worker is a teen or only works for the summer |
This is also why a teen can get federal withholding back later but not FICA. Federal income tax can be over-withheld and refunded. Correct Social Security and Medicare withholding usually stays withheld.
What Social Security and Medicare actually are
Social Security and Medicare are separate payroll tax programs, not random fees your employer invented. They show up on pay stubs because employers must withhold them from covered employee wages.
Social Security is the bigger line. At 6.2%, it is more than four times the Medicare rate. On a small teen paycheck, that usually explains most of the FICA number.
Medicare is smaller, but it still adds up. At 1.45%, it can look minor on one paycheck and still become a noticeable amount over a 10-week or 12-week summer job.
⚠️ Heads Up
Do not confuse FICA with federal income tax withholding. A teen can sometimes adjust or recover federal income tax depending on the full-year picture, but normal Social Security and Medicare withholding usually does not disappear just because earnings were low.
| Tax | What usually happens on a teen summer job | Can it come back later? |
|---|---|---|
| Federal income tax | May or may not be withheld | Sometimes, if too much was withheld |
| State income tax | Depends on the state | Sometimes |
| Social Security + Medicare | Usually withheld on regular employee wages | Usually no, unless withheld in error |
Sample teen summer job FICA math
Let’s use a realistic summer example. Say a teen earns $14 per hour, works 20 hours per week, and keeps the job for 10 weeks. That creates $280 per week and $2,800 total gross pay.
Social Security on $280 is $17.36 per week. Medicare on the same paycheck is $4.06 per week. Together, that is $21.42 every week.
Over 10 weeks, the teen pays about $173.60 to Social Security and $40.60 to Medicare, for a total of $214.20 in FICA. That is why a summer paycheck can feel smaller than expected even if federal withholding is light.
📊 Key Number
On a $2,800 teen summer job, standard employee FICA takes about $214.20 total, or roughly 7.65 cents of every dollar.
| Item | Per week | 10-week summer |
|---|---|---|
| Gross pay | $280.00 | $2,800.00 |
| Social Security | $17.36 | $173.60 |
| Medicare | $4.06 | $40.60 |
| Total FICA | $21.42 | $214.20 |
Location can change the rest of the pay stub, but not this core rule. A teen in Texas may avoid state income tax because Texas has none. A teen in California may also see state withholding. But both jobs can still have the same basic FICA treatment.

When a teen might not pay FICA
There are real exceptions, but they are narrower than most people think. The biggest mistake is assuming that “student” automatically means no Social Security or Medicare. It does not.
Some school-based jobs can qualify for a student FICA exception. Some family-employment setups can also be different. But a regular summer job at a grocery store, restaurant, private camp, landscaping company, or office usually does not fit those exceptions.
If the employer is a private business and the teen is a normal employee on payroll, the safe default assumption is that FICA is supposed to come out.
💡 Action Tip
If you think FICA might be wrong, ask one specific question: “Is this job covered by a real student or family-employment FICA exception?” That gets a better answer than saying, “But I’m only 17.”
| Situation | FICA usually applies? | Comment |
|---|---|---|
| Private summer job at a normal employer | Yes | Most common teen job outcome |
| School-related job with a true student exception | Maybe not | Rules are narrower than most workers expect |
| Teen assumes age alone creates an exception | No | Age by itself usually does not stop Social Security or Medicare withholding |
How to put this to work
1. Separate FICA from income tax. Look at Social Security, Medicare, federal withholding, and state withholding as four different buckets.
2. Do the 7.65% check. Multiply the teen’s gross wages by 0.0765. If the FICA total is close, the payroll math is probably normal.
3. Only challenge the withholding if there is a real exception. The best reasons are employer error or a specific rule, not just age or low earnings.
If you want to see how the rest of the paycheck changes by location, compare a no-state-income-tax setup like Texas with a higher-withholding state like California. That makes it easier to spot which lines are state-specific and which ones are basic FICA.
