What Payroll Deductions Are Allowed Under Federal Law?
Published: August 2026 | Last updated: August 2026
Short answer: Federal law allows deductions required by law, such as taxes and court-ordered garnishments, without limit. Deductions for the employer’s benefit, such as uniforms, tools, or cash shortages, are allowed only if they never cut an employee’s pay below the federal minimum wage or into overtime pay. The Fair Labor Standards Act sets that floor. State law can set a stricter one.
What This Is
This is an explanation of which wage deductions federal law permits and which ones it restricts, under the Fair Labor Standards Act (FLSA) and the Consumer Credit Protection Act (CCPA).
It covers legally required deductions, deductions for items that primarily benefit the employer, wage garnishments, and voluntary deductions employees agree to.
This article focuses on federal law. State law often adds requirements federal law does not, including written authorization rules for voluntary deductions.
What This Is Not
This is not a state by state deduction guide. This is not legal advice. This is not a substitute for reviewing a specific deduction with legal counsel before it goes into a pay period. Payroll should treat every deduction as a compliance decision, not a bookkeeping one.
What Counts As A Wage Deduction Under Federal Law?
A wage deduction is any amount subtracted from an employee’s gross pay before it reaches the employee, other than withholding the wage itself. Federal law does not use one blanket rule for every kind of deduction. It sorts deductions into categories, and each category has its own test.
The FLSA does not list every allowed or prohibited deduction by name. Instead, it protects two numbers: the federal minimum wage of $7.25 per hour and the overtime premium owed to non-exempt employees. Certain deductions may not cut into either number, no matter what the deduction is for.
Which Deductions Are Required By Law?
Deductions required by law are not optional for the employer or the employee, and they are not measured against the minimum wage floor described below.
Federal and state income tax withholding, the employee’s share of Social Security and Medicare tax, and legally required retirement withholding all fall under federal tax law. IRS Publication 15 (Circular E), Employer’s Tax Guide, governs how employers withhold, deposit, and report these amounts. Court-ordered garnishments also fall in this category. The Department of Labor treats these as “legally required deductions” when it calculates disposable earnings for garnishment purposes.
Which Deductions Are Restricted Because They Benefit The Employer?
This is where most violations happen. Deductions for items that are primarily for the employer’s benefit or convenience, not the employee’s, may never reduce pay below minimum wage or cut into overtime.
DOL Fact Sheet #16 lists uniforms, tools of the trade, cash register shortages, damage to employer property, and unpaid customer bills as examples. If an employee earning exactly minimum wage is required to pay for a uniform, the employer cannot deduct that cost or require reimbursement in cash. If the employee earns above minimum wage, the employer may deduct only the amount that does not bring pay below the floor in that workweek.
29 CFR 531.35 backs this with the “free and clear” rule. Wages are not considered paid unless the employee receives them finally and unconditionally. An employer cannot hand over a paycheck and then take part of it back, directly or through a required reimbursement, if doing so works like a kickback that drops pay below the legal floor.
How Do Wage Garnishments Work Under Federal Law?
A wage garnishment is a legal or administrative order requiring an employer to withhold part of an employee’s earnings for a debt. The CCPA sets the outer limit every employer must respect, regardless of how many garnishment orders arrive.
For an ordinary garnishment, meaning one that is not for child support, bankruptcy, or a tax debt, DOL Fact Sheet #30 caps the weekly amount at the lesser of 25% of disposable earnings or the amount by which disposable earnings exceed 30 times the federal minimum wage. At the current $7.25 federal minimum (last verified July 2026), that threshold is $217.50 a week. Below that amount, nothing may be garnished for an ordinary debt.
Support orders work differently. Up to 50% of disposable earnings may be garnished for child support or alimony if the employee is supporting another spouse or child, and up to 60% if not, with an additional 5% allowed when payments are more than twelve weeks in arrears. Federal or state tax debts and certain bankruptcy orders are not subject to the CCPA’s percentage caps at all.
What About Voluntary Deductions For Benefits Or Wage Advances?
Voluntary deductions cover things like health insurance premiums, 401(k) contributions, union dues, and repayment of a payroll advance the employee agreed to.
Federal law does not require written authorization before an employer starts a voluntary deduction, but it also does not remove the minimum wage floor for every voluntary deduction. Repayment of an employer issued cash advance, for example, can still be limited by the minimum wage floor depending on how it is structured. Many states require signed, itemized authorization for voluntary deductions even though federal law is silent on the point, which is one of the most common gaps employers miss.
Important Facts And Data
The federal minimum wage has been $7.25 per hour since July 24, 2009 (last verified July 2026), and it is the floor every deduction rule in this article is built on. Ordinary wage garnishments cannot exceed 25% of disposable earnings or the amount above 30 times the federal minimum wage, whichever is less. Child support garnishments can reach 50 to 65% of disposable earnings depending on arrears and dependents. Deductions for items primarily benefiting the employer, such as uniforms or tools, cannot bring pay below minimum wage or cut into overtime in any workweek. Legally required deductions, including taxes and FICA, are not subject to the minimum wage floor.
Common Misunderstandings About Payroll Deductions
“Employers can deduct anything an employee agrees to in writing.” False. Written agreement does not override the minimum wage floor for employer benefit deductions.
“Cash reimbursement instead of a payroll deduction avoids the rule.” False. The FLSA treats required cash reimbursement the same as a deduction if it works like a kickback.
“All garnishments follow the same 25% cap.” False. Child support, tax debts, and certain bankruptcy orders follow different rules than ordinary debt garnishments.
“Federal law requires written authorization for voluntary deductions.” False at the federal level. Many states require it, but the FLSA itself does not.
Real World Examples
A retail employee earning $7.25 an hour is issued a uniform and told to pay $40 toward its cost over two pay periods. Because the employee is already at the minimum wage floor, the employer cannot make this deduction at all.
A delivery driver earning $9.00 an hour damages a company vehicle. The employer cannot deduct repair costs if doing so would drop the driver’s pay below $7.25 an hour in that workweek, even if the driver was at fault.
An employee with disposable earnings of $263 in a workweek has an ordinary debt garnishment order. Because disposable earnings are below $290, only the amount above $217.50, or $45.50 that week, can be withheld.
What Should Employers Do?
Sort every deduction into one of four categories before running payroll: legally required, employer benefit, garnishment, or voluntary. Check employer benefit deductions against minimum wage and overtime every workweek, not just on average. Confirm garnishment orders against the CCPA caps before withholding, and route child support and tax garnishments through their own rules rather than a flat 25%. Check state law for written authorization requirements before starting any voluntary deduction, even though federal law does not require it.
What Should Employees Know?
A pay stub should show gross wages, every deduction, and net pay. Employees can ask payroll or HR which category a deduction falls into. An employee at or near minimum wage should never see a deduction for uniforms, tools, or property damage that drops take home pay below the federal floor.
How Should Payroll And HR Companies Help?
Payroll and HR companies should help employers apply the right test to every deduction instead of treating deductions as one category. Journey Payroll & HR builds this into how we set up client payroll, because a deduction that looks routine on a pay stub can still violate federal law if the math is not checked every workweek. Kevin Welch, CEO of Journey Payroll & HR, has built the company’s approach around explaining the why behind these rules, not just the mechanics, so employers understand the risk before it becomes a wage claim.
Frequently Asked Questions
Can an employer deduct the cost of a uniform from an employee’s paycheck? Yes, but only if the deduction never brings the employee’s pay below $7.25 an hour or cuts into overtime pay owed for that workweek.
Do employees need to sign anything before a voluntary deduction starts? Federal law does not require it, but many states do. Check state law before assuming a verbal agreement is enough.
How much of an employee’s pay can be garnished for a personal debt? For an ordinary debt, the lesser of 25% of disposable earnings or the amount above 30 times the federal minimum wage, currently $217.50 a week.
Are payroll tax withholdings considered a deduction under the FLSA’s minimum wage protections? No. Legally required withholding, including income tax and FICA, is not subject to the FLSA’s minimum wage floor.
Can an employer make an employee pay for a cash register shortage? Only if the deduction does not reduce the employee’s pay below minimum wage or into overtime. Many cash shortage deductions violate this rule.
Federal law allows legally required deductions without limit, restricts employer benefit deductions to protect the minimum wage and overtime floor, and caps most garnishments under the CCPA. The category a deduction falls into determines the rule that applies, and payroll has to check that category every workweek, not just when the deduction is first set up.
