Understanding Your U.S. Pay Stub: Taxes and Deductions

Your first American paycheck will probably be smaller than you expected. Between federal tax, state tax, Social Security and various deductions, the gap between your hourly rate and what lands in your bank account can be 20 to 30 percent or more. Reading your pay stub line by line tells you exactly where the money goes, and whether anyone is taking too much.

The top of the stub: gross pay

Gross pay is everything you earned before deductions: regular hours times your rate, plus overtime, bonuses and sometimes reported tips. Check this first every payday. Multiply your hours by your rate, confirm overtime hours are paid at time and a half, and make sure the hours match what you actually worked. Most wage theft starts here, not in the tax lines.

Federal deductions

Federal income tax withholding

Your employer withholds an estimate of your annual federal income tax from each check, based on the Form W-4 you filled in when hired. It is only an estimate; the real amount is settled when you file a tax return the following spring, and many workers get a refund.

FICA: Social Security and Medicare

Two separate lines, sometimes labeled OASDI and Medicare, totaling 7.65 percent of wages (6.2 percent Social Security, 1.45 percent Medicare). Your employer pays the same amount again on top. Note for some visa categories: certain nonresident workers, such as many F-1 students and some J-1 exchange visitors, are exempt from FICA for a period, and some countries have totalization agreements with the U.S. If FICA is wrongly withheld from an exempt worker, it can be reclaimed, but the process is slow, so flag it early with payroll.

State and local deductions

Most states withhold their own income tax, roughly 0 to 10 percent or so depending on the state and your income. Nine states, including Texas, Florida, Tennessee and Washington, have no state income tax on wages, which is one reason paychecks stretch further there. A few cities, notably New York City and Philadelphia, add local wage taxes. Some states also deduct small amounts for state disability or paid family leave insurance.

Benefit deductions

• Health, dental, vision insurance: your share of premiums, usually taken pre-tax.
• 401(k) retirement contributions: voluntary; if your employer matches contributions, that match is essentially free money.
• Other items: uniforms, tools or housing in some jobs. Rules limit what employers may deduct, deductions generally cannot push your pay below minimum wage for the workweek, and H-2A and H-2B programs have specific limits on housing and equipment charges.

A worked example

Imagine a warehouse worker in Florida earning 18 dollars an hour who worked 80 regular hours plus 5 overtime hours in a two-week pay period. Gross pay: 80 x 18 = 1,440, plus 5 x 27 = 135, so 1,575 dollars. From that, FICA takes about 120, federal withholding perhaps roughly 100 to 150 depending on the W-4, Florida takes no state income tax, and a 60-dollar health premium share leaves a net deposit somewhere around 1,250 to 1,300. The same gross in a state with income tax, or with a bigger insurance share, could land 100 or more lower. Run this arithmetic once on your own numbers and every future stub takes thirty seconds to check.

Pre-tax vs post-tax deductions

Deduction order matters. Pre-tax items, most health premiums, traditional 401(k) contributions, transit benefits, come out before taxes are calculated, so they reduce your taxable income and cost you less than their face value. Post-tax items, such as Roth 401(k) contributions or court-ordered garnishments, do not. Your stub usually groups them; if a deduction seems to be in the wrong category, ask payroll to explain it.

Year-to-date columns and your W-2

The YTD column accumulates your totals for the year. In January, your employer must send you a Form W-2 summarizing annual wages and withholdings; you use it to file your tax return. Keep every pay stub until you have checked it against the W-2, mismatches happen.

Red flags worth questioning

• No pay stub at all, or pay in cash with no record: a major warning sign.
• Hours or overtime that do not match your own records.
• Deductions you never agreed to, or vague lines like "fees".
• Being paid as a contractor with zero withholdings when you work like an employee, see our note on classification in how U.S. visa sponsorship works.

This is general information, not tax or legal advice. Tax situations vary by visa status, treaty country and state, so rely on irs.gov, dol.gov and, when needed, a qualified tax preparer familiar with nonresident issues.
