How to Read Your Pay Stub — Every Line Explained (2026)
Most people glance at net pay and ignore everything else — which is a mistake. Every other line is either money you can reduce, money you can shift to pre-tax, or an error waiting to be caught. This guide walks through every section of a US pay stub and what you can actually do about each one.
Every Pay Stub Line at a Glance
Pay Period vs. Year-to-Date (YTD)
Most pay stubs show two columns: current period and YTD totals. YTD is critical for tracking caps — like Social Security stopping at $176,100 — and making sure annual withholding is on track.
- Biweekly (26/yr) — Most common. Two months/year have 3 paychecks.
- Semi-monthly (24/yr) — 1st and 15th, or 15th and last day.
- Monthly (12/yr) — Common in academia and some professional roles.
- Weekly (52/yr) — Common for hourly workers.
Gross Pay
Your total earnings before any deductions. For salaried workers: annual salary ÷ pay periods. Always verify this matches what you're owed — payroll errors happen.
Federal Income Tax Withheld
Based on your W-4. The W-4 was redesigned in 2020 — if yours is older, withholding may be off. Under-withholding means a tax bill in April. Over-withholding means a refund (an interest-free loan to the IRS). Update your W-4 after marriage, divorce, new dependents, or a significant raise.
Social Security (6.2%) and Medicare (1.45%)
Social Security applies only to the first $176,100 of wages in 2026. Once your YTD hits that cap, the deduction stops — you'll notice a larger paycheck in Q4. Medicare has no cap; earners over $200,000 (single) pay an extra 0.9%.
State Income Tax
Nine states have none: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, Wyoming. If you recently moved states, verify your employer updated state withholding — it's one of the most common payroll errors.
Pre-Tax Deductions — How Much They Actually Save You
Pre-tax deductions reduce taxable income before taxes are calculated. Items marked FICA-exempt also avoid the 7.65% employee FICA tax. Here's the real dollar saving at three salary levels (California single filer, 2026 brackets):
Savings = federal + CA state income tax + FICA (where applicable). Use the calculator for your state and salary.
Post-Tax Deductions
These don't reduce taxable income but still appear on your stub:
- Roth 401(k) — Post-tax now, tax-free in retirement. Better if you expect a higher bracket later.
- Life insurance above $50k — Employer-paid coverage above $50k is a taxable benefit ("Imputed Income").
- Wage garnishments — Child support, student loans, court orders.
- Union dues — If applicable.
Common Errors to Check Every Few Months
- After a raise — New gross should appear the following pay period.
- After moving states — State withholding must update or you'll owe in both states.
- After open enrollment — Benefit deductions should update in January.
- After changing 401k % — Verify the contribution matches your election.
- Mid-year Social Security cap — Deduction should stop once YTD hits $176,100. If it doesn't, flag HR.
Frequently Asked Questions
Why is my take-home pay so much less than my salary?
On a $75,000 salary, you lose roughly 25–32% to federal income tax, Social Security (6.2%), Medicare (1.45%), and state income tax. In a no-tax state, a $75k salary nets about $55,000–$57,000/year. In California or New York, closer to $51,000–$53,000. Pre-tax deductions for 401k and health insurance reduce this further.
What is the difference between gross pay and net pay?
Gross pay is your salary or hours × rate before any deductions. Net pay (take-home) is what remains after federal and state income tax, FICA (Social Security + Medicare), and any benefit deductions are subtracted. The gap is typically 25–35% of gross for most workers.
When does Social Security tax stop being withheld?
Social Security tax (6.2%) only applies to the first $176,100 of wages in 2026 — this is called the wage base. Once your year-to-date earnings hit that amount, the deduction stops for the rest of the year. You'll notice your paycheck is larger in those final months.
How do pre-tax deductions save me money?
Pre-tax deductions reduce your taxable income before taxes are calculated. Contributing $23,500 to a 401(k) on a $90,000 salary saves approximately $7,355 in federal and California state income tax combined. Health insurance premiums paid through a Section 125 plan also avoid FICA taxes, saving an additional 7.65%.
What should I check on my pay stub every month?
Verify: (1) gross pay matches your salary ÷ pay periods, (2) Social Security stops once you hit $176,100 YTD, (3) state withholding updated after any move, (4) 401k contribution percentage is what you elected, (5) benefit deductions updated after open enrollment. Payroll errors are more common than most people realize.
