Withholding money from an employee’s paycheck is legal only in defined categories: taxes the employer is required to collect, court-ordered garnishments, deductions the employee authorized in writing for their own benefit, and a narrow set of business-cost deductions that cannot drop pay below the federal minimum wage. Everything else is unlawful, and getting it wrong can double the employer’s bill in court.
Deductions the Employer Has No Choice About
Federal income tax comes out of every paycheck based on the employee’s Form W-4.1Internal Revenue Service. Form W-4, Employees Withholding Certificate On top of that, employers must withhold the employee’s share of Social Security and Medicare taxes under FICA: 6.2% for Social Security up to the annual wage base, and 1.45% for Medicare on all wages, with an additional 0.9% Medicare tax kicking in once a worker’s wages pass $200,000 in a calendar year.2Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates
Wage garnishments are the other non-negotiable category. When a court or agency orders it, the employer has to withhold a portion of the paycheck to satisfy child support, alimony, unpaid taxes, or a judgment creditor’s claim.3U.S. Department of Labor. Fact Sheet 30 – Wage Garnishment Protections of the Consumer Credit Protection Act The Consumer Credit Protection Act caps how much can come out. For ordinary consumer debts, the limit is 25% of disposable earnings or the amount by which weekly disposable earnings exceed 30 times the federal minimum wage, whichever is less; with the federal minimum wage at $7.25, that protected floor is $217.50 per week.4Office of the Law Revision Counsel. 15 USC 1673 – Restriction on Garnishment Support orders reach further: up to 50% if the employee supports another spouse or child, 60% if not, and an additional 5% when payments are more than 12 weeks in arrears.
Firing an employee because their wages have been garnished for a single debt is a federal crime, carrying up to a $1,000 fine, up to a year in jail, or both. The protection covers garnishment for any one indebtedness; it does not extend to workers whose wages are being garnished for two or more separate debts.5Office of the Law Revision Counsel. 15 USC 1674 – Restriction on Discharge From Employment by Reason of Garnishment
Deductions the Employee Agreed To
Beyond mandatory withholding, an employer can take money out of a paycheck when the employee benefits from the deduction and has authorized it. There is no single federal statute demanding written consent for every deduction, but most states require a signed authorization identifying what is being withheld and how much, and getting written permission before making any voluntary deduction is the safe practice.
Typical voluntary deductions include the employee’s share of health, dental, or vision insurance premiums; elective 401(k) or 403(b) contributions; premiums for employer-sponsored life insurance; union dues; and payroll-deducted charitable contributions.
The word that matters is voluntary. The employee has to be able to revoke consent. If withholding continues after the authorization is pulled, the deduction stops being permissible and becomes illegal.
Deductions That Benefit the Employer
This is where paycheck disputes usually start. When the deduction covers something that helps the employer rather than the worker (required uniforms, tools of the trade, cash register shortages, breakage, damage to company property) the Fair Labor Standards Act draws a firm line: the deduction cannot reduce the employee’s pay for that workweek below the federal minimum wage, and it cannot cut into any overtime compensation owed.6U.S. Department of Labor. Fact Sheet 16 – Deductions From Wages for Uniforms and Other Facilities Under the Fair Labor Standards Act
What that means in practice: a worker earning exactly $7.25 per hour cannot absorb any of these costs at all. A worker earning $10 an hour can only absorb a deduction equal to the difference between actual pay and the minimum wage for hours worked that week. And an employer cannot sidestep the rule by asking the employee to pay the cost in cash instead of through the paycheck.6U.S. Department of Labor. Fact Sheet 16 – Deductions From Wages for Uniforms and Other Facilities Under the Fair Labor Standards Act
A signed consent form does not override this protection. The minimum-wage floor applies whether or not the employee agreed.
Extra Protection for Salaried Exempt Employees
Employees classified as exempt from overtime (typically salaried managers, professionals, and administrators) are protected by the salary basis test. An exempt worker must receive the same predetermined salary each pay period, and the employer generally cannot reduce it based on the quantity or quality of work.7eCFR. 29 CFR 541.602 – Salary Basis
Salary deductions are allowed in only a short list of situations: full-day absences for personal reasons; full-day sickness absences if the employer offers a bona fide paid-leave plan; unpaid FMLA leave; good-faith penalties for major safety violations; and full-day unpaid disciplinary suspensions imposed under a written policy that applies to all employees.
Nothing on that list authorizes docking an exempt employee for damaged equipment, cash shortages, partial-day absences, or unreturned property. And the consequences of doing it anyway can go well past the individual paycheck. If the employer develops an “actual practice” of improper deductions, it loses the overtime exemption for the affected employees and can owe overtime pay for every hour worked over 40 in a workweek, potentially reaching back years. The Department of Labor weighs how many improper deductions occurred, over what period, how many managers were involved, and whether the company had a policy against the practice. An isolated error that the employer promptly reimburses will not blow up the exemption, but a pattern will.8U.S. Department of Labor. Fact Sheet 17G – Salary Basis Requirement and the Part 541 Exemptions Under the Fair Labor Standards Act
Final Paychecks and Unreturned Property
When an employee leaves with a laptop, a uniform, or other company property, the impulse to hold back the cost is common. The rules don’t bend for it. A deduction from a non-exempt worker’s final paycheck still cannot push weekly pay below the minimum wage or reduce overtime owed. For a salaried exempt worker, docking the final salary to recover the cost of unreturned property violates the salary basis rule even with written permission; the employer’s option is to seek repayment separately.
Withholding the final paycheck itself is not on the table. The FLSA requires wages earned through the final work period to be paid on the next regularly scheduled payday, regardless of what property is outstanding. Many states add waiting-time penalties for late final paychecks that accumulate daily.
What an Illegal Deduction Costs
When an unlawful deduction pushes a worker below the minimum wage or shorts them on overtime, the employee can recover the unpaid wages plus an equal amount in liquidated damages under the FLSA. The doubling applies automatically unless the employer proves it acted in good faith with reasonable grounds to believe the deduction was lawful.9Office of the Law Revision Counsel. 29 USC 216 – Penalties
An employee who thinks a deduction crossed the line can file a complaint with the U.S. Department of Labor’s Wage and Hour Division, which investigates and can pursue back wages, or file a private lawsuit. State labor departments handle complaints under state wage laws.
State Law Often Goes Further
Federal law sets the floor. Where a state statute is more protective, the employer has to follow the more protective rule. Some states flatly prohibit deductions for cash shortages, breakage, or property damage no matter who was at fault or what the employee signed. Some require a separate written authorization for each individual deduction rather than a blanket form. Others impose notice periods before a deduction takes effect or cap how much can come out of any one paycheck.
Overpayment recovery is another area where state rules diverge sharply. Federal law generally lets an employer recoup an accidental overpayment through payroll, but many states require written notice, a waiting period, or explicit consent first. The federal minimum-wage floor still applies to the recovery. Both employees and employers should check their state labor department’s rules; the federal answer is only half the picture.
