A wage garnishment notice is the moment debt stops being abstract. The employer has to take money out of each paycheck and send it to a creditor, and the worker often finds out at the same time as payroll. The good news is that federal law limits how much can be taken, and many states limit it further. The bad news is that the limits are often misunderstood. This post explains the Consumer Credit Protection Act caps that set the federal floor, the typical state overlay that lowers the ceiling, and the categories of income that creditors generally cannot reach at all.
What the CCPA does
The Consumer Credit Protection Act, enforced by the Department of Labor's Wage and Hour Division, caps how much of a worker's paycheck can be garnished for most consumer debts. The cap is based on disposable earnings, which means gross pay minus the amounts the employer is required by law to withhold: federal income tax, state income tax, Social Security, and Medicare. Voluntary deductions like 401(k) contributions and health insurance do not reduce disposable earnings for garnishment math.
The federal cap for ordinary garnishments is the lesser of two numbers. Either 25 percent of disposable earnings for the week, or the amount by which disposable earnings exceed 30 times the federal minimum wage. The 30-times-minimum-wage floor protects low-wage workers. A worker earning close to minimum wage may have no garnishment at all under the federal rule because their disposable earnings do not exceed the protected floor.
The CCPA also bars an employer from firing a worker because earnings were garnished for any one debt. The protection is per debt. If a second creditor garnishes, the firing protection does not automatically extend to that second action.
How state overlay works
States can give workers more protection than the federal cap, and most do. A handful of states bar most consumer wage garnishments entirely, allowing them only for child support, taxes, and student loans. Some cap the garnishment at a lower percentage, such as 10 or 15 percent of disposable earnings. Others raise the protected weekly floor above 30 times the federal minimum wage by tying it to the state minimum wage.
The practical rule is that the worker gets whichever law is more protective. If the federal cap would allow 25 percent but the state caps at 10 percent, the creditor can only take 10 percent. If the state has no cap and uses the federal rule, the federal 25 percent applies. The court order itself will reference the controlling rule, but workers should always check the state attorney general's office or state department of labor for the current numbers.
Special categories: support, tax, and student loans
Three categories of debt operate under different rules and reach further into the paycheck.
Child support and alimony. The CCPA cap rises to 50 percent of disposable earnings when the worker supports a second family, and 60 percent when the worker does not. Both numbers go up by an additional 5 percent for arrears more than twelve weeks old. Support garnishments are administered through the state child support agency in most cases and use an income withholding order.
Federal tax debt. The IRS does not use the CCPA cap. It uses a table of exempt amounts tied to filing status and dependents, and it can leave the worker with relatively little. State tax authorities have similar rules.
Federal student loans. The Department of Education and its servicers can garnish without a court order under the Higher Education Act. The cap is 15 percent of disposable earnings, and the worker has a right to request a hearing before the garnishment starts.
What is exempt and what is not
Some income is protected from garnishment under federal law no matter the state. Social Security retirement and disability benefits, Supplemental Security Income, veterans benefits, federal civil service retirement, and most federal student aid disbursements cannot be reached by ordinary creditors. The protection is strongest while the funds are in transit or in a bank account that receives them by direct deposit. The bank is required to identify protected federal benefits in the account and shield two months of those deposits automatically under Treasury rules.
Child support garnishments can reach Social Security retirement and disability benefits, just not SSI. Federal tax debt can reach Social Security in part. The rules layer.
How a garnishment lands at the employer
For most consumer debts, garnishment requires a court judgment first. The creditor sues, wins or gets a default judgment, then files a separate writ of garnishment with the court. The court issues the writ to the employer, and the employer becomes a garnishee with its own duty to comply. The employer must:
- Deduct the lawful percentage from each paycheck.
- Send the funds to the court or directly to the creditor as the writ directs.
- Continue until the judgment is paid or the writ expires.
- Notify the worker of the deduction.
The worker usually receives a notice with rights to claim exemptions. The window to claim is short, often 10 to 30 days. Missing the window does not always waive the exemption forever, but it can let the first paychecks go out at the full allowed amount.
Common misreads we see workers make
Misread one: assuming the 25 percent cap is automatic. It is the federal ceiling, not the actual deduction. State law, the type of debt, and the worker's income level all change the number. Workers should compute the actual cap using disposable earnings and the controlling rule, not the headline percentage.
Misread two: thinking exempt benefits lose protection once deposited. They do not. Social Security and other listed federal benefits remain protected after deposit, and the bank must protect two months of those deposits automatically. Workers should not move funds out of the receiving account before claiming the exemption, because separating them complicates the bank's automatic protection.
Misread three: ignoring the right to a hearing. Every garnishment, whether court-ordered or administrative, comes with a procedural path to challenge the amount or claim an exemption. Workers who treat the notice as final lose money they did not have to lose.
Practical next steps
Step one: read the writ carefully. The notice will identify the debt, the creditor, the amount of the judgment, and the rules governing the deduction. The first 30 days after the notice are the highest-leverage period.
Step two: compute disposable earnings and the cap. Take the most recent pay stub, subtract required tax withholdings, and apply both the federal CCPA cap and the state cap. The smaller number controls.
Step three: file an exemption claim if applicable. If income falls below the protected floor, includes exempt federal benefits, or otherwise qualifies for a state exemption, file the claim with the court before the deadline. Use the state self-help portal or consult a consumer law attorney.
