Garnishment processing carries liability in both directions, which is what makes it different from most payroll tasks. Withhold too little and the employer can become liable for the debt itself. Withhold too much and the employer has violated wage protection law, may owe the employee, and in some states faces additional penalties.
There is no safe direction to err, and the calculation depends on which type of order arrived — because they do not share a single set of rules.
The most consequential structural fact, and the source of most errors: an employer receiving "a garnishment" must first identify which kind, because the limit calculation, the priority, the remittance deadline, and the response requirement all differ.
Creditor garnishments — a judgment creditor's writ following a lawsuit. Subject to the federal consumer credit protection limits and to state law, which is frequently more protective.
Child support income withholding orders, which use a standard federal form and carry the highest withholding limits and the shortest remittance deadlines.
Federal tax levies, which use an entirely different mechanism — not a percentage at all, but an exempt amount based on filing status and dependents, published annually, with everything above it taken.
State tax levies, following state-specific rules that may resemble either model.
Federal agency administrative wage garnishments, including for defaulted federal student loans, with their own statutory percentage limits.
Bankruptcy. Not a garnishment but a stop signal — the automatic stay generally halts creditor garnishments, and a Chapter 13 plan may direct payments through the trustee. Child support and certain tax obligations receive different treatment, so a bankruptcy notice requires analysis rather than a blanket halt.
Voluntary wage assignments, which are contractual rather than legal process and are subordinate to everything above.
If you fix one thing, fix this.
Disposable earnings means gross earnings less deductions required by law. Required deductions are federal, state, and local taxes, Social Security and Medicare, and mandatory retirement contributions where participation is compulsory.
Voluntary deductions are not subtracted. Health insurance premiums, elective retirement contributions, life insurance, union dues in most cases, charitable contributions, loan repayments, and flexible spending contributions are not removed before computing the limit.
The error is systematic and it runs in the employee's favor while creating employer liability: payroll staff reasonably assume "take-home pay" is the base, subtract insurance and elective deferrals, and withhold too little. The creditor's remedy in many jurisdictions is against the employer.
For an ordinary creditor garnishment, the weekly maximum is the lesser of:
25 percent of disposable earnings, or
the amount by which disposable earnings exceed thirty times the federal minimum hourly wage.
Two consequences worth understanding. The second prong is a floor protection: below a certain weekly earnings level, nothing may be garnished for a creditor debt at all. And because it is the lesser of the two, a low-earning employee is protected by the floor while a higher-earning employee is limited by the percentage.
State law frequently provides greater protection, and where it does, the more protective rule applies. Some states cap garnishment at a lower percentage, some exempt a larger amount, and some prohibit wage garnishment for consumer debt entirely. Never apply the federal calculation without checking the employee's state.
Child support withholding is permitted at substantially higher levels, and the applicable maximum depends on two facts about the employee:
Which means the employer needs to know whether the employee supports another family, and the order or the issuing agency generally indicates the applicable limit. Where it does not, ask rather than assume.
Additional child support mechanics that get missed:
Remittance is fast. Amounts withheld must be sent to the designated state disbursement unit within a short statutory period after each payday, and many states require electronic remittance. This deadline is materially shorter than the timelines employers are used to for other withholdings.
The medical support notice. A separate standard notice may require the employer to enroll the child in available health coverage, with its own response obligations and its own limits on what may be deducted.
Lump sum reporting. Many states require an employer to report a bonus, commission, severance, or other lump sum payment to a child support agency before paying it, so arrears can be attached. This is one of the most commonly missed obligations in the entire area, and it is triggered by exactly the payments employers process quickly.
Termination notification. When an employee subject to an order leaves, the employer must notify the issuing agency, generally including the last known address and the new employer if known.
Practitioners apply a percentage to a levy and get it wrong.
A federal tax levy does not use a percentage. The employer pays the employee only an exempt amount determined from the employee's filing status and number of dependents claimed on the statement provided with the levy, using tables published annually — and remits everything above that to the IRS.
Which produces two features unlike any other order. The withholding can be very large, because it is not capped at a percentage. And the levy continues until released; it is not a one-time collection.
If the employee does not return the exemption statement, the exempt amount defaults to a minimal figure, which is a conversation worth having with the employee immediately rather than after the first check.
Employees with one order frequently receive another, and the sequence matters.
The general principles: child support generally takes priority over creditor garnishments and, where the child support order predates the levy, over a federal tax levy. A pre-existing federal tax levy generally continues ahead of a later creditor garnishment. Creditor garnishments among themselves typically follow the order received, subject to state rules.
Where multiple child support orders exist and the total exceeds the applicable limit, states specify how to allocate — commonly proportionally by current support amount — and the method is state law rather than a matter of employer discretion.
Because the interactions are genuinely fact-specific, the practical rule is: do not improvise a priority decision. Contact the issuing agencies, document the analysis, and where a legal question arises, get advice. An employer who guesses wrongly can be liable to whichever party was shorted.
The rule practitioners most often do not know, and it is genuinely useful.
For an income withholding order for child support issued by a state other than the one where the employee works, the employer generally follows the law of the employee's principal place of employment for the procedural and limit questions — the maximum permitted withholding amount, the time to remit, and the required administrative steps — while following the issuing state's order for the amount ordered and the duration of the obligation.
This is what makes it possible for an employer to administer out-of-state orders consistently rather than researching every issuing state's law, and it is worth confirming against current requirements because the framework is statutory.
Structured coverage is available through Garnishments, Child Support Orders, and Other Levies, the Payroll Boot Camp, the Certified Payroll Administrator and Certified Payroll Manager programs, Best Practices for Payroll Policies and Procedures, and How to Minimize and Eliminate Payroll Penalties.
Employees ask, and the answer is no.
An employer may not stop withholding because the employee objects, disputes the debt, promises to pay directly, or produces a receipt. The order is legal process, and only the issuing court or agency can modify or terminate it. The correct response is to give the employee the notice the order requires, direct them to the issuing authority, and continue withholding.
Two related protections. Anti-discharge: federal law prohibits discharging an employee because their earnings are garnished for one indebtedness, and many states extend the protection further — to multiple garnishments, or to any adverse action rather than only discharge. Terminating an employee whose garnishment has become an administrative annoyance is among the most expensive mistakes available here.
And confidentiality: garnishment information is sensitive, it should be restricted to those who need it, and discussing it with coworkers or the employee's manager beyond what administration requires is an unnecessary exposure.
The exposures, stated plainly for a client conversation:
Garnishments arrive unpredictably, carry short deadlines, and are handled by whoever opens the mail — which is why a defined process matters more than expertise.
A single named owner, with a documented backup.
An intake log recording receipt date, employee, order type, issuing authority, response deadline, and remittance schedule. Receipt date matters because response deadlines run from it.
Immediate diarizing of the response deadline, which in many jurisdictions is measured in days.
A calculation worksheet per order, showing gross, each legally required deduction, disposable earnings, each applicable limit, and the amount withheld. This is the document that defends the employer, and it should exist for every order rather than for the difficult ones.
Employee notification with a copy of the order where required, and the contact information for the issuing authority.
A remittance calendar, with child support treated as the tightest deadline.
A review step for any employee with more than one order, before the first payroll runs.
Termination and lump sum triggers built into the offboarding and bonus processes, so the notification obligations fire without anyone remembering them.
Administrative fees where the state permits them, applied consistently — noting that they are not permitted for all order types.
The summary for a practitioner advising a client: identify the order type before calculating anything, compute disposable earnings without subtracting voluntary deductions, check the state's rule against the federal one, treat child support as the tightest deadline in the entire payroll calendar, and never let a client decide a priority question or stop an order on the employee's request. Those six habits prevent nearly every violation in this area.
Gross earnings less deductions required by law — taxes, Social Security and Medicare, and mandatory retirement contributions. Voluntary deductions are not subtracted, including health insurance premiums, elective retirement deferrals, life insurance, and loan repayments. Treating take-home pay as the base is the most common error in the area and it creates employer liability.
The lesser of 25 percent of disposable earnings or the amount by which disposable earnings exceed thirty times the federal minimum hourly wage. The second prong is a floor protection, so below a certain weekly earnings level nothing may be garnished for consumer debt. State law is frequently more protective, and some states prohibit consumer debt garnishment entirely.
They are higher: 50 percent of disposable earnings if the employee supports another spouse or child and 60 percent if not, each rising five percentage points where arrears exceed twelve weeks. Child support also carries a much shorter remittance deadline, may require enrolling a child in health coverage under a separate notice, and in many states requires reporting bonuses and lump sums before payment.
Because it does not use one. The employer pays the employee only an exempt amount determined from filing status and dependents using annually published tables, and remits everything above it. That means the withholding can be much larger than any percentage-based order, and the levy continues until released rather than being satisfied once.
Generally the law of the employee's principal place of employment governs the procedural and limit questions — maximum withholding, remittance timing, and administrative steps — while the issuing state's order governs the amount and duration of the obligation. That framework is what makes administering out-of-state orders consistently possible.
No. Only the issuing court or agency can modify or terminate an order. The employer gives the employee the required notice, directs them to the issuing authority, and continues withholding. Federal law also prohibits discharging an employee because earnings are garnished for one indebtedness, and many states extend that protection further.
