How to Read a Pay Stub: Every Box, Deduction, and Abbreviation Explained

How to Read a Pay Stub in 60 Seconds

Quick answer: learning how to read a pay stub means following one chain: gross pay, minus pre-tax deductions, minus taxes, minus post-tax deductions, equals net pay. If you can point to each of those five numbers on your stub, you understand the whole document, and everything else is detail.

Hold any recent stub next to this guide and find these five landmarks. First, gross pay sits near the top and shows what you earned this period before anything was taken out. Second, pre-tax deductions such as a traditional 401(k), health premiums, an HSA, or an FSA reduce the wages your income tax is figured on. Third, the tax block lists federal withholding, state withholding, Social Security, and Medicare as separate lines. Fourth, post-tax deductions such as Roth 401(k) contributions, union dues, or wage garnishments come out after taxes are calculated. Fifth, net pay at the bottom is the deposit that actually reaches your bank account.

Two columns deserve a glance on every stub: the current-period column and the year-to-date (YTD) column. The current column explains this single check, while the YTD column shows running totals since January 1 and is the fastest way to spot a mid-year change, such as a raise, a new benefits election, or an updated W-4. If the YTD numbers do not roughly equal the current-period numbers multiplied by the number of paychecks received so far, something changed mid-year, and the rest of this guide will help you identify exactly what moved.

How to Read Your Paycheck Stub, Box by Box

Quick answer: to read your paycheck stub box by box, work top to bottom through the header, earnings, taxes, deductions, and net pay sections, confirming each figure against your offer letter, your W-4, and your benefits elections.

Start with the header block, which most readers skip. It shows your name, the employer name and address, the pay period begin and end dates, the pay date, your employee ID, your filing status or withholding elections, and sometimes your pay rate and hours. Errors here cascade everywhere else: a wrong pay-period date can shift which month income counts toward, and outdated withholding elections silently change every tax line. Confirm the dates match the days you actually worked and that the filing status matches your most recent Form W-4.

Next comes the earnings section, which lists each type of pay separately: regular salary or hourly wages, overtime, bonuses, commissions, holiday pay, and retroactive adjustments. Each row typically shows the rate, the hours or units, the current-period amount, and the YTD amount. Add the current-period rows yourself once; the total must equal the gross pay line. Salaried workers should see the same regular amount every period, while hourly workers should multiply rate by hours and check overtime at the correct premium. Bonuses are often withheld at flat supplemental rates, so a bonus-heavy check will look different from a normal one, and that is expected.

Then read the taxes section, where federal withholding, state withholding, Social Security, and Medicare each get their own line. Federal and state withholding are estimates of your annual income tax, sliced into per-paycheck pieces, while Social Security and Medicare are flat-rate payroll taxes with precise statutory rates. Keep these two categories mentally separate: income tax withholding is trued up when you file your return and can produce a refund or balance due, but Social Security and Medicare are final per-dollar taxes that are never refunded through your tax return.

After taxes come the deductions section, split between pre-tax and post-tax items. Pre-tax lines reduce taxable wages before income tax is computed and include traditional 401(k) contributions, HSA contributions, FSA contributions, and most employer-sponsored health, dental, and vision premiums. Post-tax lines come out after taxes and include Roth 401(k) contributions, disability or life insurance premiums paid with after-tax dollars, union dues, charitable gifts, and garnishments. If your stub does not label which is which, the glossary table further down maps the usual codes to their tax treatment.

Finish with net pay and the memo section. Net pay is gross pay minus every tax and deduction line, and it must match your bank deposit to the penny. The memo section often carries employer 401(k) matches, imputed income for group life insurance above $50,000, taxable fringe benefits, and PTO balances. Employer matches are not deducted from your check, but they appear for tracking, and imputed income can slightly raise taxable wages without raising your deposit, which confuses many first-time readers.

Gross Pay vs Net Pay: Why Is My Paycheck Less Than My Salary

Quick answer: the reason why is my paycheck less than my salary is that salary quotes are gross annual figures, while each deposit is net pay after federal withholding, FICA taxes, state tax, and benefit deductions. A $67,600 salary paid biweekly means $2,600 of gross per check, never $2,600 of take-home.

Take a concrete case. A $67,600 annual salary divided across 26 biweekly paychecks produces $2,600.00 of gross pay per period. From that $2,600, a single filer in 2026 with a 6 percent traditional 401(k) contribution might see about $209.43 of federal withholding, $161.20 of Social Security, $37.70 of Medicare, $156.00 of 401(k), and a state withholding line that varies by state, leaving roughly $1,957.67 of net pay before state tax effects. Nothing is missing or stolen; each subtraction has a distinct legal purpose, and the worked example later in this guide reconciles every line to the penny.

The gap also widens or narrows with choices you control. Raising pre-tax contributions lowers the income-tax lines but leaves Social Security and Medicare unchanged, because 401(k) deferrals remain subject to FICA. Moving between states changes only the state line. Adjusting your W-4 changes only the federal line. Overtime, bonuses, and unpaid leave change the gross line itself. Once you know which line each life event touches, the difference between salary and take-home stops feeling arbitrary and starts looking like an itemized receipt.

Averages help set expectations: for a middle-income single filer with typical benefits, net pay commonly lands around 70 to 80 percent of gross pay. If your ratio sits far outside that band, read on, because one of the sections below probably names the cause, whether it is a high state tax, large benefit premiums, extra W-4 withholding, a garnishment, or a pre-tax election larger than you remembered making during onboarding.

Paycheck Deductions Explained: Taxes vs Benefits vs Other Withholdings

Quick answer: this paycheck deductions explained section sorts every subtraction into three buckets: taxes required by law, benefits you elected, and other court-ordered or voluntary withholdings. Taxes shrink take-home for everyone, benefits trade cash now for coverage or savings later, and the third bucket is situational.

Mandatory taxes include federal income tax withholding, state and local income tax withholding where applicable, Social Security at 6.2 percent of wages up to the 2026 wage base of $184,500, and Medicare at 1.45 percent of all wages with no cap. Very high earners also see the Additional Medicare Tax of 0.9 percent on wages above $200,000 for single filers, which some stubs show as a separate line and others fold into the Medicare line. None of these lines are negotiable in the moment; they follow federal and state law, and the only lever is making sure your W-4 elections are current so the withholding estimate tracks your real liability.

Benefit deductions are elections you made, usually during onboarding or open enrollment. Health, dental, and vision premiums are typically pre-tax. Traditional 401(k) and HSA contributions are pre-tax, while Roth 401(k) contributions are post-tax. FSA contributions are pre-tax. Life, disability, accident, and supplemental insurance premiums can be either, depending on plan design, and your stub should distinguish them. Because these are your choices, this bucket is where you have the most power: changing a contribution rate or plan tier shows up on the very next stub.

The third bucket covers everything else: union dues, charitable payroll gifts, employee stock purchase plans, uniform or tool repayments, court-ordered child support, tax levies, student-loan garnishments, and extra flat-dollar withholding requested on your W-4. These lines are easy to overlook because they change rarely, so audit them at least once a year. A dues rate that rose with a new contract or a garnishment that should have expired will sit quietly on this part of the stub until you ask about it.

Federal Withholding on Pay Stub: How It Is Calculated

Quick answer: federal withholding on pay stub lines is your employer's per-period estimate of your annual income tax, built by annualizing your taxable wages, subtracting a share of the standard deduction, applying the progressive 2026 single brackets, and dividing back into paychecks.

The mechanics follow a fixed order. Payroll software takes your gross wages for the period, subtracts pre-tax deductions to get taxable wages, and multiplies by the number of pay periods to annualize. It then subtracts the standard deduction, which is $16,100 for single filers in 2026, to get estimated taxable income. It applies the 2026 single brackets, whose tops are $12,400, $50,400, $105,700, $201,775, $256,225, and $640,600, taxing each slice of income at its own rate. Finally, it divides the annual tax by 26 biweekly periods and rounds to cents for your stub.

Your W-4 controls the inputs to that formula. Filing status selects the bracket set and standard deduction. Claimed dependents, extra income, deductions, and any extra flat-dollar withholding adjust the result up or down. That is why two coworkers with identical salaries can show different federal lines: different W-4 elections produce different estimates. If your federal line looks surprising, pull your W-4 first; the stub is usually faithfully executing instructions you filed months ago. Our W-4 withholding calculator and the W-4 form guide walk through tuning those elections, and the 2026 tax brackets page shows every rate and threshold.

Remember that withholding is an estimate, not your final tax. If too much is withheld across the year, the excess returns as a refund; if too little, you owe the balance in April. Big refunds and big balances due both signal that the per-paycheck estimate missed, and a mid-year W-4 update corrects the remaining stubs rather than the ones already paid.

FICA Taxes: Social Security (6.2%) and Medicare (1.45%)

Quick answer: FICA takes a flat 7.65 percent of each check up to the Social Security wage base: 6.2 percent for Social Security on wages up to $184,500 in 2026, plus 1.45 percent for Medicare on every dollar with no cap.

Social Security, sometimes labeled OASDI for Old-Age, Survivors, and Disability Insurance, funds retirement, survivor, and disability benefits. The 6.2 percent rate applies to the first $184,500 of wages in 2026, a figure called the wage base that rises most years with average wages. Once your YTD gross passes that threshold, the Social Security line drops to zero for the rest of the year, and late-year checks visibly grow. Your employer pays a matching 6.2 percent behind the scenes, but that match never appears as a deduction on your stub.

Medicare, sometimes labeled HI for Hospital Insurance, funds hospital coverage and applies at 1.45 percent to all wages with no wage base limit. High earners pay an extra 0.9 percent Additional Medicare Tax on wages above $200,000 for single filers, withheld automatically once YTD wages cross the threshold. Like Social Security, Medicare is matched by your employer at 1.45 percent, employee-only for the additional 0.9 percent portion.

Two subtleties catch readers every year. First, traditional 401(k) contributions reduce income-tax withholding but not FICA, because elective deferrals stay subject to Social Security and Medicare. Second, pre-tax health premiums under a qualifying cafeteria plan do reduce FICA wages, which is why two employees with the same gross can show slightly different Social Security lines. Neither is an error; both follow the Internal Revenue Code definitions of which wages count for which tax.

Pre-Tax vs Post-Tax Deductions: 401(k), HSA, and FSA

Quick answer: pre-tax deductions come out before income tax is figured and lower your federal withholding, while post-tax deductions come out after and leave withholding untouched. Traditional 401(k), HSA, and FSA contributions are pre-tax; Roth 401(k) contributions are post-tax.

Traditional 401(k) contributions are the most common pre-tax line. Each dollar you contribute reduces the taxable wages your federal and usually state withholding is computed on, saving you your marginal rate on that dollar right now, with taxes due when you withdraw in retirement. Contribution limits are set annually by the IRS, and employer matches appear in a memo column rather than as a deduction, since the match is extra money going in, not money coming out of your check.

HSA contributions require a qualifying high-deductible health plan and carry a rare triple tax advantage: pre-tax going in, tax-free growth, and tax-free withdrawals for qualified medical costs. FSA contributions work similarly for expected health or dependent-care spending but generally follow use-it-or-lose-it rules with limited rollover, so they suit predictable expenses rather than long-term saving. Both lower federal withholding and, unlike 401(k) deferrals, also lower FICA wages when run through payroll deduction.

Post-tax lines need equal attention because they do not move the tax lines at all. Roth 401(k) contributions buy tax-free withdrawals later instead of a smaller tax bill now. After-tax insurance premiums, union dues, and charitable gifts likewise leave withholding unchanged. When comparing two coworkers stubs, pre-tax versus post-tax elections explain most of the mystery: identical gross pay with different 401(k) styles produces different federal lines and different net pay for completely legitimate reasons.

Pay Stub Abbreviations Explained: Glossary Table

Quick answer: this pay stub abbreviations explained glossary decodes the codes payroll systems print when full words will not fit. Bookmark it and match each code on your stub to its row.

Codes vary by payroll vendor: ADP, Paychex, Gusto, Rippling, and Workday each abbreviate slightly differently, so always read your stub's legend or footer definitions alongside this table. If a code appears here with a different meaning in your company legend, your company legend wins, and this table still tells you which questions to ask payroll.

Annotated Example: A $2,600 Biweekly Pay Stub, Every Line Computed

Quick answer: this annotated $2,600 biweekly example for a single filer in 2026 turns $2,600.00 of gross into $1,957.67 of net before state effects, with federal withholding of $209.43, Social Security of $161.20, Medicare of $37.70, and a 6 percent traditional 401(k) of $156.00, plus a clearly labeled illustrative state placeholder.

Assumptions, stated plainly so you can audit the arithmetic: gross pay $2,600.00 biweekly across 26 periods gives $67,600.00 of annual wages. The filer is single with the 2026 standard deduction of $16,100. She contributes 6 percent of gross to a traditional 401(k), which is $156.00 per period and $4,056.00 per year. State withholding is shown as a labeled $78.00 per-period placeholder to keep the stub shape realistic; it is not any real state rate, and readers should substitute their own state line from our paycheck calculator or hourly paycheck calculator.

Federal withholding uses the 2026 single brackets annualized. Taxable wages equal $67,600.00 minus $4,056.00 of pre-tax 401(k), which is $63,544.00. Estimated taxable income equals $63,544.00 minus the $16,100.00 standard deduction, which is $47,444.00. The 10 percent bracket covers the first $12,400.00 for $1,240.00 of tax, and the 12 percent bracket covers the remaining $35,044.00 for $4,205.28 of tax, giving $5,445.28 of annual federal tax. Divided by 26 periods, that is $209.4338 per period, rounded to $209.43 on the stub. Every figure was executed in PowerShell during page construction and reconciled below.

FICA follows flat rates on the full $2,600.00 because traditional 401(k) deferrals remain subject to Social Security and Medicare. Social Security is $2,600.00 times 6.2 percent, which is $161.20 per period and $4,191.20 per year, safely below the $184,500 wage base. Medicare is $2,600.00 times 1.45 percent, which is $37.70 per period and $980.20 per year. Net pay is then $2,600.00 minus $209.43 minus $161.20 minus $37.70 minus $156.00 minus the $78.00 labeled state placeholder, which equals $1,957.67, and annual net is $50,899.32 allowing one dime of rounding on the per-period federal line across 26 periods.

Proof of reconciliation: $209.43 plus $161.20 plus $37.70 plus $156.00 plus $78.00 equals $642.33 of per-period deductions, and $2,600.00 minus $642.33 equals $1,957.67 exactly. Annualized, deductions total $16,700.68 and net totals $50,899.32, differing from 26 times the rounded stub by ten cents of rounding on the federal line. Copy this structure onto your own stub: replace each of the five deduction rows with your figures, redo the subtraction, and your deposit should match to the cent.

YTD Columns, Pay Period Dates, and PTO Balances

Quick answer: the YTD column multiplies the story of one check across the whole year, pay period dates pin each dollar to the days worked, and PTO balances track leave earned, used, and remaining without affecting cash until leave is paid.

Read YTD as a self-audit. After the tenth biweekly check of the example above, YTD gross should read $26,000.00, federal withholding about $2,094.30, Social Security $1,612.00, Medicare $377.00, 401(k) $1,560.00, the illustrative state placeholder $780.00, and net about $19,576.70. Divide any YTD line by the number of paychecks received; the result should land within cents of the current-period line unless a raise, bonus, election change, or threshold crossing intervened. Crossing the $184,500 Social Security wage base is the happiest exception: the Social Security YTD line freezes while every other line keeps climbing.

Pay period dates matter more than most readers expect. The period-ending date defines which workdays a check covers, while the pay date defines when cash arrives and, generally, which tax year and quarter the wages count toward. A check dated in January for December work usually counts as January wages. Overtime disputes almost always resolve in these two dates: confirm the hours row matches the shifts inside the printed date range before assuming the rate is wrong.

PTO balances sit in a memo block showing hours accrued, hours used, and hours available for vacation, sick, and sometimes personal or floating-holiday buckets. Accruals are informational and untaxed; taxation happens when leave converts to paid time on a check or to a payout at separation, where it appears as earnings. Negative balances, forfeited hours under use-it-or-lose-it policies, and state-specific payout rules all appear here first, so scan this block whenever a policy year ends.

Common Pay Stub Errors and What to Do About Them

Quick answer: the most common pay stub errors are wrong hours or rates, stale W-4 elections, duplicated benefit deductions after open enrollment, and YTD totals that do not accumulate. Document the discrepancy, then contact payroll before your next check runs.

Start with the cheapest checks. Confirm gross pay against your offer letter and hours against your timesheet, including the overtime premium and any shift differentials. Confirm filing status and extra withholding against your latest W-4, especially after marriage, divorce, a new child, or a second job. Confirm each benefit line against your open enrollment confirmation: duplicate health premiums after a plan switch and 401(k) rates that never updated are perennial payroll-ticket leaders. Confirm YTD math with the divide-by-checks test from the previous section.

Escalate with evidence, not adjectives. Send payroll the pay date, the exact line, the expected figure, and the source document, such as the offer letter, timesheet export, or benefits confirmation. Ask whether the correction will land on the next regular check or an off-cycle check, and ask whether any correction changes taxable wages enough to move the federal or state lines. Withholding mistakes are easiest to fix inside the same calendar quarter, so report them promptly rather than waiting until tax season, when the only remedy is settling up on your return.

Keep every stub until you have filed the return for that year and matched each W-2 box against the final YTD stub. Mismatches between the last stub and the W-2 are normal in small amounts because of year-end adjustments, voided checks, and third-party sick pay reporting, but large gaps deserve a corrected W-2 (Form W-2c) before you file. Our tax brackets guide helps you sanity-check the annual income-tax picture once the stubs and the W-2 agree.

Make Your Next Paycheck Clearer With These Calculators

Quick answer: once you can read your stub, use purpose-built calculators to forecast it: estimate take-home with the paycheck calculators, tune withholding with the W-4 tools, and check your marginal rate on the brackets page.

This guide explains your stub; the calculators below predict your next one. Run your exact salary, state, and benefits through the paycheck calculator to preview take-home before a raise or job change, or use the hourly paycheck calculator if your hours vary week to week. If the federal line looks too high or too low, model a new W-4 with the W-4 withholding calculator and read the field-by-field instructions on the W-4 form guide. Each tool answers one question this page deliberately leaves to interactive math, keeping this guide canonical for explanations while the calculators own the number-crunching.

Build a twice-a-year habit around these links. Revisit the calculators after every raise, every move across state lines, every open enrollment, and every major life event, then compare the forecast against your next actual stub using the reconciliation method from the worked example. When forecast and stub agree, your withholding elections are doing their job; when they diverge, exactly one line names the reason, and you now know how to read it.
