Your net check is the money that actually lands in your bank account on payday after every deduction has been pulled from your gross pay. Gross pay is what your employer agrees to pay you; the net check is what remains once federal income tax, Social Security, Medicare, state and local taxes, insurance premiums, retirement contributions, and any court-ordered withholdings have come out. The math is simple in form and messy in practice: gross pay minus all deductions equals your net check. Earn $5,000 gross in a pay period, lose $1,700 to taxes and benefits, and your net check is $3,300.
Understanding what “net check” means is really about understanding the stack of deductions sitting between the two numbers. Each one has its own rules, and each one is worth checking on your pay stub.
The Taxes That Come Out First
Every standard paycheck in the United States is subject to several layers of required withholding your employer must process before paying you.
Federal Income Tax
Your employer withholds federal income tax from each paycheck based on the information you provide on Form W-4 and your total earnings.1Internal Revenue Service. Tax Withholding for Individuals The W-4 accounts for your filing status, number of jobs, dependents, and any additional withholding you request.2Internal Revenue Service. Form W-4 (2026) Employers are legally required to deduct and withhold this tax each time they pay wages.3Office of the Law Revision Counsel. 26 USC 3402 – Income Tax Collected at Source
Withholding is only an estimate of your annual tax bill spread across pay periods, so the total taken out during the year may not match what you actually owe. The difference is settled when you file your return, as either a refund or a balance due. Life events like getting married, having a child, or picking up a second job change what your withholding should look like, and the IRS recommends updating your W-4 when those happen.4Internal Revenue Service. How to Get Tax Withholding Right
Social Security and Medicare
The Federal Insurance Contributions Act requires a separate set of deductions that fund Social Security and Medicare. For 2026, Social Security tax is 6.2% of your wages up to $184,500.5Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet Once your cumulative earnings hit that cap, no more Social Security tax is withheld for the rest of the year. Medicare tax is 1.45% of all your wages with no cap.6Office of the Law Revision Counsel. 26 USC 3101 – Rate of Tax
Earn more than $200,000 in a calendar year and your employer must also withhold an Additional Medicare Tax of 0.9% on wages above that threshold.7Internal Revenue Service. 2026 Publication 926 This extra tax comes entirely from your paycheck with no employer match, and withholding starts in the pay period your year-to-date wages cross $200,000 and continues through year-end.8Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates
State and Local Taxes
Most states impose their own income tax, and many cities or counties add a local income tax on top. These withholdings follow your state’s tax brackets and any local rates for where you live or work. A handful of states have no income tax at all, and workers there see a noticeably higher net check than workers earning the same gross in a high-tax state. About five states also require employees to contribute to a state disability insurance or paid family leave program through a separate payroll deduction, which further trims the net check in those states.
Why Pre-Tax and Post-Tax Deductions Change Your Take-Home
Not every deduction is subtracted at the same point in the calculation, and the order matters. Pre-tax deductions such as traditional 401(k) contributions, health insurance premiums, and HSA contributions come out of your gross pay before federal income tax and FICA are calculated. Every dollar you route through a pre-tax deduction lowers the income those taxes apply to.
Post-tax deductions are taken after taxes have been calculated on your full earnings. Roth 401(k) contributions, union dues, and some supplemental insurance policies fall in this bucket. They do not reduce your current tax bill; in the Roth case, the trade-off is tax-free withdrawals in retirement. When you look at your pay stub, each deduction should be labeled pre-tax or post-tax, and switching an eligible deduction from post-tax to pre-tax can raise your net check without changing your coverage.
Voluntary Deductions You Elected
Beyond mandatory taxes, most workers route part of their paycheck toward benefits and savings. These elections usually happen when you start a job or during annual open enrollment, and you can generally adjust them when your circumstances change.
Health, dental, and vision insurance. Employer-sponsored insurance premiums are one of the largest voluntary deductions for most workers. Your employer typically pays a share of the premium and the remainder is withheld from your paycheck, often on a pre-tax basis. The dollar amount depends on the plan tier you pick (individual, employee-plus-spouse, or family) and the coverage level.
Retirement contributions. Contributions to a 401(k), 403(b), or similar workplace plan come out of your paycheck before you ever see the money. For 2026, the employee contribution limit is $24,500, with higher catch-up amounts available starting at age 50.9Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Traditional contributions are pre-tax and reduce taxable income now; the money is taxed when you withdraw it in retirement.
HSAs and FSAs. A Health Savings Account lets you set aside pre-tax money for qualified medical expenses if you are enrolled in a high-deductible health plan.10Internal Revenue Service. Publication 969 (2025), Health Savings Accounts and Other Tax-Favored Health Plans The 2026 HSA limit is $4,400 for self-only coverage and $8,750 for family coverage, and unused funds roll over indefinitely and stay with you if you change jobs.11Internal Revenue Service. IRS Notice 2026-05 A Flexible Spending Account works similarly for out-of-pocket medical costs, with a 2026 health care FSA limit of $3,400, but most FSA funds follow a use-it-or-lose-it rule at the end of the plan year.
Deductions You Cannot Opt Out Of: Garnishments
Some deductions are neither taxes nor voluntary. They come out because a court or government agency ordered it. Garnishments for unpaid consumer debts, child support, alimony, tax debts, and defaulted student loans all run through payroll. They are taken after taxes and typically after voluntary deductions, and the caps depend on the type of debt.
For ordinary consumer debts like credit cards or medical bills, the garnishment cannot exceed the lesser of 25% of your disposable earnings for that week, or the amount by which your weekly disposable earnings exceed 30 times the federal minimum wage.12Office of the Law Revision Counsel. 15 USC 1673 – Restriction on Garnishment With the federal minimum wage at $7.25 per hour, that threshold works out to $217.50 per week, and disposable earnings at or below that level cannot be garnished at all for consumer debts.13U.S. Department of Labor. State Minimum Wage Laws
Support orders allow a much bigger share of your paycheck to be taken. If you are supporting another spouse or dependent child beyond the one covered by the order, up to 50% of your disposable earnings can be garnished. If you are not supporting anyone else, the ceiling rises to 60%. Either figure goes up an extra 5% if you are more than 12 weeks behind on payments, pushing the maximums to 55% and 65%. Federal and state tax levies are also exempt from the 25% consumer-debt cap; the IRS calculates a small amount to leave you based on filing status and dependents and takes the rest.12Office of the Law Revision Counsel. 15 USC 1673 – Restriction on Garnishment
Checking Your Net Check Against Your Pay Stub
Your pay stub is the best tool for confirming that your net check is right. It should list gross pay, each individual deduction (with the amount and whether it is pre-tax or post-tax), and the resulting net pay. No federal law requires your employer to hand you a pay stub, but most states require one in some form, either printed or available electronically.14U.S. Department of Labor. Are Pay Stubs Required? – FLSA Advisor
A few items are worth a close look:
- Year-to-date totals for gross pay, tax withholdings, and benefit deductions should match what your rate and elections predict.
- Social Security withholding should stop once your year-to-date earnings reach $184,500 in 2026. If it keeps coming out past that point, flag it with payroll.5Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet
- Benefit deduction amounts should match what you elected, especially in the first few checks after open enrollment.
- Any wage garnishment should stay within the legal cap for that type of debt.
If something looks off, start with your employer’s payroll or HR department. Employers are required to keep accurate records of hours worked and wages paid, and most errors clear up quickly once your records and theirs are compared.
The Floor Under Your Pay
Federal law limits how far certain deductions can cut into your paycheck. If your employer requires you to pay for uniforms, tools, or other work-related costs through payroll deductions, those deductions cannot drop your earnings below the federal minimum wage of $7.25 per hour or eat into any overtime pay you are owed.15U.S. Department of Labor. Handy Reference Guide to the Fair Labor Standards Act Tax withholdings and voluntary benefit elections are not subject to this rule and can bring take-home below the minimum wage, but employer-imposed deductions cannot. If your regular payday passes and a check has not arrived, you can file a complaint with the U.S. Department of Labor’s Wage and Hour Division or your state labor department.16U.S. Department of Labor.
