Illinois provides significantly stronger wage garnishment protections than the federal baseline. While federal law allows garnishment of up to 25% of disposable earnings, Illinois caps consumer debt garnishment at 15% of gross income. This lower limit means Illinois workers keep more of their paycheck when facing garnishment.

How Much Can Be Garnished in Illinois? A Worked Example
The math matters more than the percentages. In Illinois, a creditor with a judgment for consumer debt is limited by two tests, and must use whichever takes less: the percentage cap, and the protected floor of $630.00 per week (45× the Illinois minimum wage of $14.00/hour). Everything at or below that floor is untouchable.
Here is what that means at three income levels. The table assumes roughly 25% of gross pay goes to legally required deductions (federal and state taxes, Social Security, Medicare); your actual disposable earnings — the number the law actually uses — will vary with your tax situation.
| Gross weekly pay | Estimated disposable earnings | Max weekly garnishment | Share of disposable pay |
|---|---|---|---|
| $600.00 | $450.00 | $0.00 | 0.0% |
| $900.00 | $675.00 | $45.00 | 6.7% |
| $1,500.00 | $1,125.00 | $225.00 | 20.0% |
Notice how the protected floor changes the picture for lower incomes — at $600 per week gross, nothing can be garnished at all in Illinois. To run your own paycheck through the current formula, use the Illinois wage garnishment calculator.
Illinois vs. the Federal Baseline
| Rule | Federal (CCPA) | Illinois |
|---|---|---|
| Consumer debt limit | 25% of disposable earnings | 15% of disposable earnings |
| Protected weekly floor | $217.50 (30× federal minimum wage) | $630.00 per week (45× the Illinois minimum wage ($14.00/hr)) |
| Child support | 50–65% of disposable earnings | 50% supporting another family / 60% otherwise, +5% for arrears |
| Federal student loans | 15% of disposable earnings | 15% (federal administrative rule) |
| Head-of-household protection | None | No additional state protection |
Illinois's rules protect more of your paycheck than the federal baseline — the higher protected floor means lower-income workers often cannot be garnished at all.
Illinois's 15% Limit
The Illinois Wage Deduction Act limits garnishment to 15% of gross (not disposable) earnings. Because gross income is higher than disposable income, and the percentage is lower, Illinois workers benefit from a double layer of protection. For example, someone earning $1,000/week gross would have a maximum garnishment of $150 in Illinois, compared to potentially $187.50 or more under federal law.

Additional Illinois Protections
Illinois uses the greater of the federal minimum wage threshold or the state minimum wage threshold, whichever provides more protection to the worker. With Illinois's minimum wage at $14.00/hour, the state threshold can be significantly higher than the federal $217.50/week. Illinois also prohibits employers from firing employees for any number of garnishments, providing broader employment protection than federal law.

The Illinois Garnishment Process
In Illinois, a creditor must obtain a judgment and then file a wage deduction proceeding. The court issues a wage deduction order, which is served on your employer. You receive notice and have the right to file a claim of exemption. Illinois requires a court hearing before the garnishment can begin if you file an objection. See our guide on How to File a Wage Garnishment Exemption for help with objections.
Exemptions
Illinois exempts Social Security, veterans benefits, unemployment compensation, workers compensation, and public assistance from garnishment. Retirement benefits also receive strong protection. If garnishment would cause undue hardship, you can petition the court for a reduction. See our exemption filing guide.
Illinois Wage Garnishment FAQ
Can my wages be garnished in Illinois without a court judgment?
Not for consumer debts. A creditor must sue you, win a judgment, and obtain a garnishment order before your employer withholds anything. The exceptions that skip the lawsuit are child support orders, federal student loans (administrative wage garnishment), and tax levies — those follow their own separate procedures.
How much of my paycheck is completely safe in Illinois?
For consumer debts: everything at or below $630.00 per week (45× the Illinois minimum wage ($14.00/hr)) — plus whatever the percentage cap leaves above that line. Note that tax debts play by different rules: Illinois Department of Revenue can levy wages for state tax debts.
What income can never be garnished in Illinois?
Key protections include: Garnishment limited to 15% of gross wages (vs. 25% federal); 45x state minimum wage protected ($630/week); Among the most protective states in the nation. Once protected funds are commingled in a bank account, tracing them can get complicated — keep records of exempt deposits.
Can I be fired for having my wages garnished in Illinois?
Federal law (CCPA §304) prohibits firing an employee because of a single garnishment order, no matter the state. Protection for multiple garnishments varies — if you face more than one order, review your state's rules or speak with an employment attorney before assuming you are protected.
