The Secret Life of Your Paycheck

Open any US pay stub and you'll find a small case study in how the country funds itself. A chunk goes to the federal government, a part may go to your state capital, a slice funds Social Security, and what's left is what actually reaches your bank account. Most employees glance at the bottom-line number and move on, but the line items above it are where the real story lives.

Here's a clear, practical 2026 tour of how US payroll actually works: what gets withheld, why it exists, and the numbers quietly shaping every paycheck in the country.

The anatomy of a paycheck

Gross pay is everything you earned before anything is taken out, base wages, overtime, bonuses, commissions. From there, two kinds of deductions reduce it: the ones the law requires, like taxes, and the ones you've chosen, like health premiums or a 401(k) contribution. What's left is net pay, the only figure most people actually remember.

The gap between the two can be surprisingly wide. A worker earning a $70,000 annual salary might watch 20–30% of it disappear into withholding before it ever reaches a checking account, and exactly how much depends heavily on which state that paycheck was issued in.

To see where that money actually goes, it helps to slow the paycheck down and look at it line by line. Take a $70,000 salary spread across 26 pay periods: each biweekly check opens at $2,692.31 in gross pay, and from there the subtractions begin.

Illustrative example for a $70,000 annual salary. Actual withholding depends on your W-4 elections, state and benefits.

FICA: the tax everyone pays

The single most consistent line on any US paycheck isn't income tax: it's FICA, the Federal Insurance Contributions Act tax that funds Social Security and Medicare. Unlike income tax, FICA doesn't depend on your filing status or the deductions you claim. It's a flat percentage of wages, split evenly between employee and employer, paycheck after paycheck, for as long as you work.

Social Security takes 6.2% of wages, matched by another 6.2% from your employer, but only up to a yearly cap, $184,500 in 2026. Once your earnings exceed that limit during the calendar year, Social Security tax is no longer withheld from the rest of your wages for that year. Medicare, on the other hand, applies its 1.45% to every single dollar, with no ceiling at all. High earners face one more layer: an Additional Medicare Tax of 0.9% on any wages above $200,000, with no employer match on that slice.

Minimum wage and the overtime clock

The Fair Labor Standards Act (FLSA) is the federal law setting the floor for hourly pay nationwide, and that floor hasn't moved since 2009. The federal minimum wage still sits at $7.25 an hour, though most states have set their own rate, and employers are always required to pay whichever number is higher.

Overtime is usually paid at 1.5 times an employee's regular hourly rate for any hours worked over 40 in a workweek. Whether a salaried employee qualifies depends on salary thresholds and job duties. Under federal law, employees earning less than $684 a week ($35,568 a year) are generally entitled to overtime, regardless of their job title. Some states, such as New York, set higher salary thresholds, and the rule that provides greater protection to the employee applies.

The state tax patchwork

Federal payroll taxes are the same across the US, but state income taxes vary. Some states set their own rates, while nine states have no state income tax at all. That's why two people with the same salary can take home different amounts depending on where they live.

Living in one of these states doesn't automatically mean a lower total tax bill, the difference usually reappears somewhere else, in sales or property tax. But for payroll purposes specifically, it means one less line item quietly shrinking every paycheck.

Payday: how often, and how

Pay frequency isn't left entirely up to an employer. Many states set rules for how often wages must be paid, and how fast a final check must go out once someone leaves a job. Weekly and biweekly schedules are most common for hourly workers, keeping the gap between work and payment short. Semi-monthly pay, twice a month on fixed dates, is the more common choice for salaried staff, since it simplifies benefits math. Monthly pay is legal in fewer states and is more common for senior roles.

Direct deposit is now the default for most US employees, though paper checks and pay cards still exist for workers without a bank account. Whatever the method, the underlying math never changes: gross pay, minus what's owed, equals what's yours.
