Paycheck Taxes on an L-1 Visa: What to Expect (With a Real Example)

If you just moved to the U.S. on an L-1 visa, the first pay stub can be a shock. Lines like “Social Security” and “Medicare” show up, your net pay is lower than your offer letter math, and you start wondering if you’re being taxed differently because you’re on a visa.

Most of the time, you’re not. L-1 paycheck taxes usually look very normal. The confusing part is that the U.S. splits taxes into multiple buckets, and your pay stub shows them as separate line items.

Quick reality check: L-1 paycheck taxes usually look “normal”

For most L-1 workers who are paid as W-2 employees, the paycheck formula is basically:

• Gross pay (salary ÷ pay periods)
• Minus pre-tax deductions (health insurance, 401(k), commuter, etc.)
• Minus payroll taxes (FICA: Social Security + Medicare)
• Minus income tax withholding (federal, and possibly state/local)
• = Net pay (what hits your bank)

What shows up on an L-1 pay stub (and what each line means)

Your pay stub is basically a receipt. Here’s what the common lines mean and which ones you can influence.

Do L-1 workers pay FICA (Social Security + Medicare)?

In most cases, yes. If you’re an L-1 employee on payroll (W-2), your employer typically withholds FICA at the same rates as any other employee.

That’s why you’ll see both lines on your stub:

• Social Security (a percentage up to the annual wage base cap)
• Medicare (a percentage on wages; there can be an extra Medicare surtax above certain income levels)

Federal withholding + W-4: the part you can actually change

Federal income tax on your pay stub is withholding — a prepayment toward what you’ll owe when you file. It is not a “final bill” and it is not a special visa tax.

Your employer uses your W-4 to guess how much federal tax to withhold from each paycheck. If your W-4 is incomplete, filled out conservatively, or you have multiple income sources, withholding can come out high.

Two common “new to the U.S.” mistakes:

• Leaving W-4 blank-ish. Payroll systems may default to a higher-withholding setup to avoid under-withholding.
• Not accounting for a working spouse. Two incomes with a simple W-4 can create an under/over-withholding problem.

State income tax: the biggest swing factor in take-home pay

Many L-1 workers focus on federal taxes — but in real life, state income tax is what makes two paychecks feel totally different.

If you work in Texas, there’s no state income tax withheld. If you work in California, state withholding can be material on every paycheck.

And it’s not just “where your company is headquartered.” It’s usually where you physically work (and sometimes where you live). If you live in one state and work in another, ask payroll what state setup they’re using — it’s a common source of bad withholding.

Real example: $120,000 salary, paid biweekly (with numbers)

Let’s do an intentionally simple example so you can eyeball your own stub. Assumptions:

• $120,000 salary
• Paid biweekly (26 checks)
• Single filer, standard situation
• No pre-tax deductions (to keep the math clean)
• Work state example: California (state tax withheld) — compare to Texas (no state withholding)

That $3,512 isn’t a promise — it’s a checkpoint. If your net is wildly different, it’s usually because you have big pre-tax deductions (health insurance, 401(k)), different filing status assumptions, or different state rules.

How to Put This to Work (3 steps)

1. Identify the fixed vs adjustable lines. Social Security + Medicare (FICA) are mostly fixed-rate; federal/state income tax are withholding you can tune with forms.
2. Run a state reality check. Use California and Texas as a contrast, then match your work state and compare to one real pay stub.
3. Update your forms once, then re-check after 2 paychecks. If you change your W-4 or state withholding, give payroll 1–2 cycles to catch up, then review your new net pay.
