Quick Answer
To read a pay stub, locate your gross pay (total earned before deductions), then subtract taxes and other withholdings to find your net pay (take-home amount). As of July 2025, federal income tax withholding is calculated using 7 tax brackets ranging from 10% to 37%. Understanding every line prevents costly payroll errors.
Knowing how to read a pay stub means understanding the difference between what you earn and what you actually keep — two numbers that can differ by 20% to 35% for most American workers, according to IRS withholding data. A pay stub is the itemized record your employer provides each pay period showing gross earnings, every deduction, and your net pay. If you’ve ever stared at yours wondering where your money went, this guide breaks it down line by line.
Most people never scrutinize their pay stub until something goes wrong — an incorrect deduction or a missing benefit contribution. Catching errors early can save you hundreds of dollars per year.
What Is Gross Pay and Why Does It Start Every Pay Stub?
Gross pay is the total amount you earn before any deductions are taken out — it is always the first and largest number on your pay stub. For salaried employees, gross pay equals your annual salary divided by the number of pay periods. For hourly workers, it equals hours worked multiplied by your hourly rate, plus any overtime.
The Fair Labor Standards Act (FLSA), enforced by the U.S. Department of Labor, requires that non-exempt employees receive 1.5 times their regular rate for all hours worked beyond 40 in a workweek. Overtime pay is added directly to gross pay, which is why your gross figure can vary week to week even on a “fixed” schedule.
YTD (Year-to-Date) Totals
Most pay stubs show both current-period earnings and year-to-date (YTD) totals. YTD figures reflect cumulative gross pay, deductions, and taxes from January 1 through the current pay date. These numbers matter most at tax time — your YTD gross should match Box 1 of your W-2 form, adjusted for pre-tax benefits.
Key Takeaway: Gross pay is your starting earnings figure before any deductions. Under the FLSA, hourly workers earn at least 1.5x their base rate for overtime hours. Always verify your YTD gross matches your W-2 at year-end to catch payroll discrepancies early.
What Tax Deductions Appear on Every Pay Stub?
Federal, state, and local taxes are the largest deductions on any pay stub and are withheld by your employer before you receive a single dollar. Understanding these lines is the core skill of learning how to read a pay stub.
Federal Income Tax (FIT)
Federal income tax withholding is based on the information you provided on your IRS Form W-4 and your income level. The IRS uses a progressive bracket system with 7 rates: 10%, 12%, 22%, 24%, 32%, 35%, and 37% for tax year 2025. Your employer uses IRS Publication 15-T to calculate the exact amount withheld each period.
FICA Taxes: Social Security and Medicare
The Federal Insurance Contributions Act (FICA) mandates two separate payroll taxes. Social Security is withheld at 6.2% of wages up to the 2025 wage base of $176,100, while Medicare is withheld at 1.45% with no income cap, according to the Social Security Administration’s 2025 contribution base. High earners also pay an additional 0.9% Medicare surtax on wages above $200,000.
State and Local Income Tax
State income tax appears on pay stubs in the 41 states that impose it. Rates vary significantly — from a flat 3.07% in Pennsylvania to a top marginal rate of 13.3% in California. Nine states, including Texas and Florida, have no state income tax at all, so this line simply will not appear on your stub.
Key Takeaway: Federal taxes, FICA, and state taxes typically reduce gross pay by 20%–30% for middle-income earners. The 2025 Social Security wage base is $176,100 — once your YTD earnings pass this threshold, Social Security withholding stops, noticeably increasing your net pay.
| Pay Stub Line Item | Rate / Amount (2025) | Who Pays It |
|---|---|---|
| Federal Income Tax | 10%–37% (7 brackets) | Employee |
| Social Security (FICA) | 6.2% up to $176,100 | Employee + Employer (matched) |
| Medicare (FICA) | 1.45% (no wage cap) | Employee + Employer (matched) |
| Additional Medicare Surtax | 0.9% on wages over $200,000 | Employee only |
| State Income Tax | 0% – 13.3% (varies by state) | Employee |
| 401(k) Contribution (pre-tax) | Up to $23,500 annually | Employee (voluntary) |
| Health Insurance Premium | Employer-specific (pre-tax) | Employee + Employer (shared) |
What Are Pre-Tax Deductions and How Do They Lower Your Tax Bill?
Pre-tax deductions are amounts subtracted from your gross pay before taxes are calculated — they directly reduce your taxable income, which lowers the amount of federal and state tax you owe. This is one of the most valuable sections on any pay stub.
Common pre-tax deductions include contributions to employer-sponsored 401(k) and 403(b) retirement plans, Health Savings Accounts (HSAs), Flexible Spending Accounts (FSAs), and health, dental, and vision insurance premiums under a Section 125 cafeteria plan. For 2025, the IRS allows employees to contribute up to $23,500 to a 401(k), according to IRS retirement contribution limits.
“Many workers leave money on the table by not maximizing pre-tax benefit elections. Even a modest increase in your 401(k) contribution rate — say, 1% to 2% — costs far less in take-home pay than the gross dollar amount suggests because the contribution reduces your taxable income.”
Post-tax deductions, by contrast, are subtracted after taxes are calculated. These include Roth 401(k) contributions, garnishments, union dues, and certain life insurance premiums. Understanding which bucket each deduction falls into tells you exactly why your taxable wages differ from your gross pay.
If you’re also managing debt alongside your paycheck, understanding how your income breaks down can help you make smarter decisions — whether you’re figuring out whether to pay off debt or build an emergency fund first or evaluating monthly loan payments.
Key Takeaway: Pre-tax deductions like 401(k) and HSA contributions reduce your taxable income dollar-for-dollar. Contributing the 2025 maximum of $23,500 to a 401(k) can save thousands in annual taxes — see the IRS contribution limits page for exact thresholds and catch-up rules.
How Do You Calculate Net Pay From a Pay Stub?
Net pay — also called take-home pay — is the amount deposited into your bank account after all taxes and deductions have been subtracted. This is what you actually have to spend, save, or invest each pay period.
The formula is straightforward: Gross Pay minus Pre-Tax Deductions equals Taxable Wages. Then, subtract all applicable taxes (federal, FICA, state, local). Finally, subtract any post-tax deductions to arrive at net pay. A small discrepancy of even $10–$20 per pay period can add up to over $500 per year if a payroll error goes uncorrected.
Gig workers and freelancers face a slightly different picture. Without an employer withholding taxes automatically, self-employed individuals owe the full 15.3% FICA rate (both employee and employer portions) as self-employment tax, as outlined by the IRS self-employment tax guidance. If you’re navigating variable income, our guide on budgeting for gig workers with variable income walks through how to plan when your net pay changes every period.
Your net pay figure also matters when lenders evaluate loan applications. Lenders typically use net income — not gross income — when calculating your debt-to-income (DTI) ratio for personal loans or auto financing. Understanding this distinction can affect whether you qualify for credit and at what rate.
Key Takeaway: Net pay equals gross pay minus all deductions and taxes. Self-employed workers owe a 15.3% self-employment tax per the IRS — nearly double the employee-only FICA share — making accurate pay stub literacy critical for anyone transitioning between employment types.
How Do You Spot and Fix Pay Stub Errors Before They Cost You?
Pay stub errors are more common than most employees realize and knowing how to read a pay stub carefully is your first line of defense. The most frequent mistakes involve incorrect tax withholding, missing employer contributions, and miscalculated overtime.
Start by verifying that your Social Security Number (SSN) and filing status match your W-4 on file with HR. A wrong filing status — claiming “Single” instead of “Married Filing Jointly,” for example — can cause significant overwithholding or underwithholding. The IRS estimates that roughly 1 in 5 workers have inaccurate withholding, according to the U.S. Government Accountability Office (GAO).
Also check your employer’s 401(k) match. If your employer matches 50% of contributions up to 6% of salary, verify that the match amount appears correctly each pay period. Employer contributions are typically shown as a separate, non-taxable line item. Missing or incorrect matches are among the most costly and overlooked payroll errors.
Understanding your pay stub also gives you a stronger foundation when applying for credit. Lenders and credit reporting agencies like Equifax, Experian, and TransUnion may request pay stubs as income verification. If you’re building your financial profile, learning how to read a credit report for the first time pairs directly with this skill. Similarly, if you’re preparing for a major purchase like a vehicle, reviewing your net pay is essential before exploring auto loan pre-approval versus pre-qualification options.
Key Takeaway: Roughly 1 in 5 workers have incorrect tax withholding, per the GAO. Compare your W-4 filing status, FICA withholdings, and employer 401(k) match every quarter. Catching a single payroll error early can recover hundreds of dollars before year-end.
Frequently Asked Questions
What is the difference between gross pay and net pay on a pay stub?
Gross pay is your total earnings before any deductions, while net pay is what remains after federal taxes, FICA, state taxes, and benefit deductions are subtracted. For most workers, net pay is 20%–35% lower than gross pay depending on tax bracket and elected benefits.
How do I read a pay stub if I have multiple jobs?
Each employer withholds taxes independently, which can cause under-withholding when combined income pushes you into a higher bracket. Use the IRS Tax Withholding Estimator to calculate the correct W-4 elections for your total income. Adjust withholding at your primary job to avoid a surprise tax bill in April.
What does YTD mean on a pay stub?
Year-to-date (YTD) shows the cumulative total of earnings, deductions, and taxes from January 1 through the current pay date. Your YTD gross income should match the taxable wages reported in Box 1 of your W-2 form at year-end, minus any pre-tax deductions like 401(k) contributions.
Why is my federal income tax withholding $0 on my pay stub?
Zero federal withholding typically means your W-4 claims “exempt” status, or your income is below the withholding threshold for your filing status. Employees who claimed exempt but have taxable income may owe a balance when they file. Review your W-4 with your HR department if this appears unexpectedly.
Does a pay stub count as proof of income for a loan application?
Yes — most lenders, including banks, credit unions, and online lenders, accept recent pay stubs (typically the last 2–3) as primary income verification. Lenders use your net pay to calculate your debt-to-income ratio, so knowing how to read a pay stub accurately directly impacts your borrowing power. If your income is variable, you may also need to show bank statements or tax returns.
How do I know if my employer is withholding too much Social Security tax?
Check your YTD Social Security withholding each pay period. Once your YTD gross wages exceed $176,100 in 2025, Social Security withholding must stop. If it continues past that threshold, contact your payroll department immediately — excess withholding is recoverable, but only if you catch it before year-end or claim it as a credit on Form 1040. For workers building a first financial foundation, our guide on net worth vs. income explains why what you keep matters more than what you earn.
