If you’re wondering why your paycheck is so low compared to the salary you were quoted, the short answer is that a stack of deductions comes out before the money ever reaches your account. Federal, state, and sometimes local income taxes, Social Security and Medicare, health insurance premiums, retirement contributions, and other elected or mandated withholdings routinely take 25% to 35% off a gross paycheck. For a first check from a new employer, timing of the pay period often makes the shortfall even bigger.
If This Is Your First Paycheck From a New Job
A first paycheck that looks especially thin is usually a timing issue, not a deduction issue. Employers pay on a fixed schedule, and unless your start date lined up with the first day of a pay period, that initial deposit only covers the partial days you worked before the cycle closed. Start on a Wednesday in a biweekly period and you might see three days of pay instead of ten.
Many employers also pay in arrears, meaning each check covers a previous work period rather than the current one. A one- or two-week lag in the payroll calendar pushes the first deposit later and shrinks the window it covers. The second or third paycheck is typically the first one that reflects a full cycle. If the amount still looks wrong after that, the reasons below are where to look.
Federal Income Tax Withholding
The biggest single line on most pay stubs is federal income tax. Your employer is required by law to estimate what you’ll owe the IRS for the year and withhold that amount across your paychecks.1Office of the Law Revision Counsel. 26 USC 3402 – Income Tax Collected at Source The calculation runs off the W-4 you filled out when you were hired, including your filing status and any credits or extra income you reported.
Federal tax uses progressive brackets, so different slices of your income get taxed at different rates. For 2026, a single filer pays 10% on the first $12,400 of taxable income, 12% up to $50,400, and 22% up to $105,700, with higher earners going up to 37%.2Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 The standard deduction ($16,100 single, $32,200 married filing jointly in 2026) comes off your taxable income before those brackets apply, so effective withholding is usually lower than your top bracket implies.
A W-4 set up incorrectly is one of the most common reasons take-home pay feels off. You may be over-withholding, which produces a refund but shrinks every paycheck, or under-withholding, which produces a bill in April.
State and Local Income Taxes
Most states levy their own income tax on top of federal withholding. Some use a flat rate, others use progressive brackets, and a handful have no state income tax at all.
The layer that catches people out is local. Thousands of cities, counties, and school districts in roughly 16 states charge their own payroll taxes. In major cities, local rates can hit 3% to 4% of earnings. Elsewhere it may be a flat few dollars per pay period. These show up as separate line items on your stub and can total hundreds of dollars a year.
Social Security and Medicare
After income tax, the next mandatory deduction is FICA: 6.2% of every dollar you earn for Social Security and 1.45% for Medicare, a combined 7.65%.3Office of the Law Revision Counsel. 26 USC 3101 – Rate of Tax Your employer matches those amounts separately; that match doesn’t appear on your stub. On a $50,000 salary, FICA alone takes about $3,825 a year.
The 6.2% Social Security portion only applies to earnings up to $184,500 in 2026.4Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet Once your year-to-date wages cross that cap, the Social Security deduction disappears for the rest of the year and take-home pay jumps. Medicare has no cap. Earners above $200,000 also pay an extra 0.9% Additional Medicare Tax on wages over that threshold.5Internal Revenue Service. Topic No. 560, Additional Medicare Tax
Benefits, Retirement, and Other Deductions
The voluntary side of the paycheck is where employees have the most control and often the least awareness of what they signed up for.
Health Insurance
Employer-sponsored health coverage is the largest voluntary deduction for most workers. The employee share of the premium averages roughly $130 a month for individual coverage and over $600 a month for a family plan. Premiums typically come out pre-tax, which lowers your taxable income but also means the money is gone before you see it. Dental, vision, and HSA contributions add more on top, all pre-tax.
Retirement Contributions
Every dollar you defer into a 401(k) or 403(b) comes straight off your paycheck. The 2026 contribution limit is $24,500, with an $8,000 catch-up at age 50 and an $11,250 catch-up at ages 60 through 63.6Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Traditional (pre-tax) contributions cut your taxable income, so a $500 pre-tax deferral at a 22% marginal rate reduces take-home pay by about $390. Roth 401(k) contributions come out of after-tax dollars, so your paycheck drops by the full contribution amount. Workers auto-enrolled at 6% to capture an employer match are often surprised at what that represents per check.
FSAs and Other Line Items
Flexible Spending Accounts for medical or dependent care are pre-tax. Life insurance, disability, and legal plans usually come out post-tax. Some employers also deduct for commuter benefits, gym memberships, or payroll charitable giving. Individually these are small; stacked, they can easily be $50 to $200 per paycheck.
State-Mandated Programs
Some states require payroll deductions for disability insurance or paid family leave that you didn’t elect. Employee contributions range from about 0.2% to over 1% of wages. These show up as separate lines and are easy to misread as errors. Your state’s labor department website will list which programs apply.
Wage Garnishments
If money is being pulled to pay a debt, that’s a garnishment. Your employer receives a court order or government directive and must withhold a portion of your pay and send it to the creditor. Common triggers are child support, defaulted student loans, back taxes, and civil judgments.
Federal law caps most consumer-debt garnishments at the lesser of 25% of your disposable earnings or the amount by which weekly disposable earnings exceed 30 times the federal minimum wage ($217.50 per week at $7.25 an hour).7Office of the Law Revision Counsel. 15 USC 1673 – Restriction on Garnishment Workers earning near minimum wage may be protected entirely. Child support and federal tax levies follow steeper rules: child support can reach 50% to 65% of disposable earnings, and IRS levies use a formula based on filing status and dependents. If a garnishment appears on your stub that you don’t recognize, ask payroll for a copy of the order so you know which debt it covers and how long it will run.
Payroll Errors and Missing Overtime
When none of the categories above explains the gap, the paycheck may be genuinely wrong. Errors are common for new hires whose paperwork is still processing. An incorrect pay rate keyed at onboarding, a missed shift in the timekeeping system, or a wrong tax jurisdiction can all produce a real mistake rather than an expected shortfall.
Overtime is the biggest single issue. Non-exempt employees must be paid at least one and a half times their regular rate for every hour worked beyond 40 in a workweek.8Office of the Law Revision Counsel. 29 US Code 207 – Maximum Hours The most common problem is misclassification, meaning your employer treats you as exempt when you actually qualify for overtime. Under current federal enforcement standards, a salaried employee must earn at least $684 a week ($35,568 a year) and perform specific managerial, professional, or administrative duties to be legitimately exempt.9U.S. Department of Labor. Earnings Thresholds for the Executive, Administrative, and Professional Exemption If your salary is below that threshold, or your actual duties don’t match the exemption, you are likely owed overtime regardless of your job title.
Compare your pay stub line by line against your own records: hours, rate, deduction amounts, and tax withholding. If something doesn’t match, raise it in writing with HR or payroll. Legitimate errors are usually corrected in the next cycle with back pay. Keep copies of your timesheets, emails, and the disputed stub.
If your employer refuses to fix a wage problem, or you believe overtime is being systematically withheld, you can file a confidential complaint with the Department of Labor’s Wage and Hour Division at 1-866-487-9243.10U.S. Department of Labor. How to File a Complaint Federal law prohibits retaliation for reporting a wage issue.11Office of the Law Revision Counsel. 29 US Code 215 – Prohibited Acts Workers who win FLSA claims can recover unpaid wages plus an equal amount in liquidated damages, effectively doubling the recovery.12Office of the Law Revision Counsel. 29 US Code 260 – Liquidated Damages
How to Raise Your Take-Home Pay
If the paycheck is technically correct but still feels too low, your best lever is the W-4. Most people fill it out once at hiring and never touch it again, even after getting married, having a child, or picking up a second job. Any of those events can throw withholding well off in either direction.
The IRS offers a free Tax Withholding Estimator that walks through your income, deductions, and credits and shows whether you’re on pace to owe or get a large refund.13Internal Revenue Service. Tax Withholding Estimator If you’re over-withholding, submit a new W-4 to your employer to shrink the amount taken each period. The IRS suggests checking each January and after any major life event.14Internal Revenue Service. Managing Your Taxes After a Life Event
Don’t overcorrect. Under-withholding by more than $1,000 for the year, without meeting the safe harbor of paying at least 90% of this year’s tax or 100% of last year’s, triggers an IRS underpayment penalty that accrues interest until paid.15Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty The goal is a withholding level that keeps your refund small and your paychecks as large as possible without landing you in penalty territory.
