Why Your Pay Stub Matters
Your pay stub is the most important financial document you receive every two weeks — and most people never read it. It tells you exactly where your money goes before it reaches your bank account. Understanding each line item helps you catch errors (which happen more often than you think), optimize your tax withholding, and understand your true compensation beyond just your salary.
This guide walks through every section of a typical pay stub with real examples and explains what each deduction means for your finances.
The 5 Sections of Every Pay Stub
Most pay stubs follow the same structure regardless of your employer. Here is what each section contains:
| Section | What it shows | What to check |
|---|---|---|
| Gross pay | Total earnings before any deductions | Hours × rate matches. Overtime calculated correctly (1.5x after 40 hrs) |
| Federal taxes | Federal income tax withheld | Matches your W-4 elections. Too much = big refund (interest-free loan to IRS) |
| State/local taxes | State income tax, city tax if applicable | Correct state. Some cities (NYC, Philadelphia, Portland) have additional taxes |
| FICA | Social Security (6.2%) + Medicare (1.45%) | SS stops at $168,600 wage base (2026). Medicare has no cap |
| Voluntary deductions | 401(k), health insurance, HSA, FSA, life insurance | Contribution percentages match your elections. Premium amounts correct |
Gross Pay vs Net Pay: Where Your Money Goes
On a $75,000 salary ($2,884.62 per biweekly paycheck), here is a typical breakdown of deductions:
| Line item | Amount | What it is |
|---|---|---|
| Gross pay | $2,884.62 | Your full biweekly earnings |
| Federal income tax | -$310.00 | Based on W-4 elections, 22% bracket |
| Social Security (6.2%) | -$178.85 | OASDI tax, capped at $168,600/yr |
| Medicare (1.45%) | -$41.83 | No income cap. Additional 0.9% above $200K |
| State income tax | -$115.38 | Varies by state (0% in TX, FL, WA — up to 13.3% in CA) |
| 401(k) contribution (6%) | -$173.08 | Pre-tax, reduces your taxable income |
| Health insurance | -$185.00 | Your share of premium (employer pays the rest) |
| HSA contribution | -$82.69 | Pre-tax, triple tax advantage |
| Net pay (take-home) | $1,797.79 | 62.3% of gross — what hits your bank account |
Only 62% of your gross pay actually reaches your bank account. The other 38% goes to taxes, retirement savings, and insurance. Understanding this breakdown is essential for budgeting accurately. Use our take-home pay calculator to see your specific numbers.
Federal Income Tax Withholding
Your employer withholds federal income tax based on your W-4 form elections. The amount depends on your filing status, number of allowances, and any additional withholding you requested. Common issues to watch for:
Too much withheld: If you received a large tax refund last year (over $1,000), you are overwithholding — essentially giving the government an interest-free loan. Adjust your W-4 to reduce withholding and increase your take-home pay. A $2,400 refund means you could have had $200 more per month all year.
Too little withheld: If you owed taxes last year, you are underwithholding. This can trigger IRS penalties. Increase your W-4 withholding or make estimated quarterly payments.
Use our income tax calculator to estimate your tax liability, then adjust your W-4 so your withholding matches.
FICA Taxes: Social Security and Medicare
Social Security (OASDI): 6.2% of your gross pay up to $168,600 (2026 wage base). Your employer also pays 6.2%, totaling 12.4%. Once you earn $168,600 in a calendar year, Social Security withholding stops for the rest of the year — you will see a bump in net pay for your remaining paychecks.
Medicare: 1.45% of all earnings with no cap. Earnings above $200,000 (single) or $250,000 (married) are subject to an additional 0.9% Medicare surtax. Your employer matches the base 1.45% but does not match the surtax.
Together, FICA taxes take 7.65% of your pay — $5,737.50 on a $75,000 salary. Check our Social Security estimator to see what benefits this is building toward.
Pre-Tax vs Post-Tax Deductions
Understanding the difference saves you money:
| Deduction type | Examples | Tax benefit |
|---|---|---|
| Pre-tax | Traditional 401(k), health premiums, HSA, FSA, commuter benefits | Reduces taxable income. $173 pre-tax 401(k) saves ~$42 in taxes per paycheck at 24% bracket |
| Post-tax | Roth 401(k), life insurance over $50K, disability insurance, garnishments | No current tax benefit, but Roth grows tax-free |
Every dollar contributed pre-tax reduces your current tax bill. At the 22% bracket, a $500/month pre-tax 401(k) contribution only reduces your take-home by $390 because of the $110 tax savings. This makes pre-tax deductions cheaper than they appear. See the impact with our Roth vs Traditional 401(k) calculator.
Common Pay Stub Errors to Watch For
Wrong hours or overtime. Verify your reported hours match your actual time worked. Overtime must be calculated at 1.5x your regular rate for hours over 40/week (federal law). Some states require overtime for hours over 8/day.
Incorrect tax withholding. If you recently moved states, got married, or had a child, your withholding may not reflect the change. File an updated W-4 with HR.
Missing or wrong deductions. Verify your 401(k) percentage matches what you elected. Check health insurance premiums against your enrollment confirmation. If you changed plans during open enrollment, verify the new premiums took effect.
Wrong filing status. If your pay stub shows "Single" but you file as "Married Filing Jointly," you are likely overwithholding. Update your W-4.
Year-to-Date (YTD) Totals: What to Check
The YTD section on your pay stub is your running total for the calendar year. Review these annually (or at least quarterly) to verify that your total gross pay matches your expected annual salary, your 401(k) contributions are on track to max out ($23,500 in 2026), your Social Security withholding stops after reaching the $168,600 wage base, and your health insurance deductions match your plan selections. Your final pay stub of the year should closely match your W-2 form. If they do not match, flag it with HR before tax filing season.
How to Optimize Your Take-Home Pay
Maximize pre-tax deductions: Every dollar in your traditional 401(k), HSA, or FSA reduces your taxable income. At the 22% bracket, $100 pre-tax costs you only $78 in take-home pay.
Right-size your withholding: If you got a large refund, reduce withholding via W-4 to put that money in your paycheck each month instead of waiting for a refund. Use the IRS Tax Withholding Estimator or our calculator.
Use commuter benefits: If your employer offers pre-tax transit or parking benefits ($315/month max in 2026), you save $75-100/month in taxes on your commute costs.
Check for employer HSA contributions: Some employers contribute $500-$1,500/year to your HSA. This is free money — make sure you are enrolled in the HDHP that qualifies you to receive it.
Every Line on Your Pay Stub Explained
Gross Pay: Your total earnings before any deductions. For salaried employees, this is your annual salary divided by pay periods (26 for biweekly, 24 for semi-monthly). For hourly workers, it is hours worked times hourly rate plus any overtime at 1.5x.
Federal Income Tax: Based on your W-4 elections and the 2026 tax brackets. If this seems too high or low, adjust your W-4. A large tax refund means too much is being withheld — you are giving the government an interest-free loan. A balance due means too little withholding — increase it to avoid penalties. Our W-4 Withholding Calculator determines the right amount.
Social Security (OASDI): 6.2% of gross pay up to $168,600 in 2026. Once your year-to-date earnings exceed this cap, Social Security withholding stops and your remaining paychecks for the year are larger. High earners may see a noticeable jump in take-home pay in the fall when they hit the cap.
Medicare: 1.45% of all gross pay with no cap. Earnings above $200,000 (single) trigger an Additional Medicare Tax of 0.9%, bringing the total to 2.35% on high earnings.
State and Local Tax: Varies by state from 0% (Texas, Florida, etc.) to 13.3% (California top rate). Our State Tax Guide shows rates for all 50 states.
Pre-Tax Deductions (reduce taxable income): 401(k) contributions, traditional IRA, health insurance premiums, HSA contributions, FSA contributions, commuter benefits. These reduce your taxable income, saving you money on every paycheck.
Post-Tax Deductions: Roth 401(k) contributions, life insurance above $50,000, union dues, garnishments. These come out after taxes are calculated and do not reduce your tax burden.
The Deductions That Catch New Workers Off Guard
First-time employees are often shocked when their first paycheck is 25-35% less than expected. A new graduate earning $60,000/year ($2,307 per biweekly paycheck) expects roughly that amount — but takes home approximately $1,620-1,730. The gap is not a mistake; it is the combined effect of mandatory and voluntary deductions that collectively consume a significant portion of gross pay.
Federal income tax withholding is the largest deduction for most workers, consuming 10-22% of gross pay depending on your tax bracket and W-4 elections. A single filer earning $60,000 with standard W-4 settings has approximately $280-340 withheld per biweekly paycheck. This withholding is an estimate — the actual tax owed is determined when you file your return. If too much was withheld, you receive a refund. Too little means you owe money in April. The goal is to land within $200-500 of your actual liability.
FICA taxes (Social Security + Medicare) are the second-largest mandatory deduction at a combined 7.65% of gross pay: 6.2% for Social Security (on the first $168,600 of earnings in 2026) and 1.45% for Medicare (no income cap, plus an additional 0.9% on earnings above $200,000). On a $2,307 biweekly paycheck, FICA deducts approximately $176 — non-negotiable, no deductions reduce it, and no W-4 adjustment changes it.
State and local income taxes vary from $0 (in nine states with no income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, Wyoming) to $100-250+ per paycheck in high-tax states like California, New York, and New Jersey. Some cities add additional local income taxes — New York City residents pay city income tax of 3-3.9% on top of state and federal, adding $70-90 per biweekly paycheck on a $60,000 salary.
Pre-Tax vs Post-Tax Deductions: Why the Distinction Matters
Pre-tax deductions are subtracted from your gross pay before taxes are calculated, reducing your taxable income. Every dollar contributed pre-tax saves you 22-37 cents in federal income tax (depending on your bracket) plus 7.65 cents in FICA plus your state tax rate. Common pre-tax deductions: traditional 401(k) contributions, health insurance premiums (most employer plans), HSA contributions, FSA (flexible spending account) contributions, and commuter benefits.
Example impact: a $500/month 401(k) contribution on a $60,000 salary reduces your annual taxable income to $54,000 — saving approximately $1,100 in federal income tax plus $459 in FICA = $1,559 in annual tax savings. The $500 monthly contribution only reduces your take-home pay by approximately $370 because the government effectively subsidizes 26% of the contribution. This is why pre-tax 401(k) contributions are the single most effective tax reduction strategy available to most employees.
Post-tax deductions are subtracted after taxes are calculated and provide no immediate tax benefit. Common post-tax deductions: Roth 401(k) contributions (taxed now, tax-free in retirement), disability insurance premiums, life insurance premiums above $50,000 in employer-provided coverage, union dues, and wage garnishments. Roth 401(k) contributions appear on your stub as a post-tax deduction — your current paycheck is smaller than with a traditional 401(k), but withdrawals in retirement will be completely tax-free.
The employer contribution line shows money your employer contributes on your behalf that does not reduce your paycheck. This typically includes: employer 401(k) match (the most important — verify it matches your expected amount), employer health insurance contribution (often $300-800/month for family coverage that you would otherwise pay in full), and employer-paid life insurance and disability premiums. If your employer matches 50% of your 401(k) contributions up to 6% but you see no match on your stub, you may not be contributing enough to trigger the match — the most expensive mistake in employee benefits.
Year-to-Date Totals: The Numbers That Catch Tax-Time Errors
Every pay stub includes year-to-date (YTD) totals for each category — the cumulative sum from January 1 through the current pay period. These YTD figures are your most powerful tool for catching errors, verifying W-2 accuracy, and ensuring your tax withholding is on track.
YTD gross pay should match your expected annual salary prorated to the current date. If you earn $60,000/year and you are looking at your mid-year stub (June 30), YTD gross should be approximately $30,000. If it is significantly different, investigate: missed overtime, incorrect pay rate, or payroll errors can compound over months if not caught early.
YTD federal tax withheld is the most actionable number on your stub. Multiply it by (total pay periods / elapsed pay periods) to project your annual withholding. If your projected annual withholding differs from your estimated annual tax liability by more than $1,000, submit an updated W-4. Example: you have had $4,000 withheld through 12 of 26 pay periods. Projected annual withholding: $4,000 × (26/12) = $8,667. If your estimated annual tax is $7,000, you are over-withholding by $1,667 — that is $128/month that could be in your pocket or your investment account instead of sitting as a 0% loan to the IRS.
