Illinois Wage Garnishment 2026: The 15% Rule Explained

Illinois vs Federal: Why Illinois Protects More

Two legal frameworks govern wage garnishment in Illinois: the federal Consumer Credit Protection Act (15 U.S.C. § 1673) and the Illinois Wage Garnishment Act under 735 ILCS 5/12-803. When two rules conflict, the law that protects the worker more applies. Illinois nearly always wins that comparison for ordinary creditor debts.

The federal rule caps garnishment at the lesser of 25% of disposable earnings or the amount by which disposable earnings exceed 30 times the federal minimum wage ($7.25/hour × 30 = $217.50/week protected). Disposable earnings means gross pay minus legally required deductions — primarily federal, state, and local taxes and FICA.

The Illinois rule caps garnishment at the lesser of 15% of gross wages or the amount by which gross wages exceed 45 times the Illinois minimum wage ($15.00/hour × 45 = $675/week protected). Illinois uses gross, not disposable — so the deduction base is different from the federal calculation.

Concrete example: A worker earns $900/week gross. After taxes, disposable income might be $675. Federal allows 25% of $675 = $168.75 or ($675 − $217.50) = $457.50 — the lesser is $168.75. Illinois allows 15% of $900 = $135 or ($900 − $675) = $225 — the lesser is $135. The creditor takes $135 under Illinois law, not $168.75 under federal law.

That $33.75/week difference is not trivial over a garnishment that may run for months or years. Illinois creditors regularly receive less than federal law would allow, which is exactly what the legislature intended when it tightened the cap.

The $675 Floor: What "45 Times Minimum Wage" Actually Means

The floor calculation is anchored to Illinois's minimum wage, not the federal minimum wage. As of January 1, 2026, Illinois's minimum wage is $15.00 per hour. Multiply $15.00 × 45 = $675 per week. That is the protected weekly floor.

If your gross weekly earnings are $675 or less, the second prong of Illinois's two-part test results in zero or a negative number — meaning the floor protection swallows the entire paycheck. A worker earning $650/week gross cannot have any wages garnished by an ordinary creditor in 2026, regardless of the judgment amount.

Why 45 times? The multiplier is a policy choice that translates minimum wage into living-expense coverage. The idea is that someone earning at or near minimum wage needs their full paycheck to cover basic costs. Illinois has updated this formula as the minimum wage has risen, meaning the protected floor increases automatically when the legislature raises the wage floor.

Chicago exception: Chicago has its own minimum wage that in some years exceeds the state floor. For employees who work primarily in Chicago, the garnishment calculation should use the Chicago minimum wage if it is higher than the state rate — because Illinois law uses the minimum wage applicable to the worker's employment, and courts applying the spirit of the statute look to the effective floor. In 2026, if Chicago's minimum wage is higher than $15.00, multiply that Chicago rate by 45 to get the protected weekly amount. Employers and workers in Chicago should verify the current Chicago rate through the Chicago Department of Business Affairs and Consumer Protection.

When minimum wage increases mid-year, the new protected floor applies going forward. If Illinois enacts a mid-year wage increase (which has happened in recent legislative sessions), recalculate your floor using the new rate from the effective date.

Step-by-Step: Calculating Your Illinois Garnishment

Illinois law uses a two-prong test and applies whichever result is smaller (more protective). Here is how to calculate it for any salary:

Step 1: Identify your gross weekly wages. This is before taxes, health insurance, retirement, or any other deduction. "Gross" means the full number on your pay stub before any lines are subtracted.

Step 2: Calculate prong A — 15% of gross. Multiply your gross weekly wages by 0.15.

Step 3: Calculate prong B — excess over $675. Subtract $675 from your gross weekly wages. If the result is negative, prong B equals zero.

Step 4: Apply the lesser. The maximum creditor can garnish is whichever of prong A or prong B is smaller.

Scenario 1 — Worker earning $800/week gross: Prong A: $800 × 15% = $120 Prong B: $800 − $675 = $125 Lesser = $120. Maximum garnishment = $120/week.

Scenario 2 — Worker earning $600/week gross: Prong A: $600 × 15% = $90 Prong B: $600 − $675 = −$75 (negative → $0) Lesser = $0. Result: zero garnishment possible.

Scenario 3 — Multiple creditors: Illinois limits the total amount garnished from a single paycheck to 15% gross regardless of how many creditors hold judgments. If Creditor A already has a garnishment order capturing the full $120 from the $800/week worker, Creditor B receives nothing until Creditor A's judgment is satisfied. Illinois operates on a first-come, first-served queue — the date the employer received the garnishment summons determines priority.

Monthly salary workers: Convert to weekly equivalent before applying the formula. Divide monthly gross by 4.333 (52 weeks ÷ 12 months) to get weekly gross for the calculation.

What Creditors Can and Cannot Do in Illinois

Illinois requires a court judgment before wages can be garnished for most private debts. A creditor cannot simply send a letter to your employer demanding deductions. The sequence is: creditor sues, court enters judgment, creditor requests a garnishment summons from the clerk, employer receives the summons, and deductions begin — in that order. No judgment means no garnishment.

Notice requirements under 735 ILCS 5/12-705: After serving the employer, the creditor must also serve the debtor (you) with a copy of the garnishment summons. Illinois gives employers two business days to notify the employee after receiving the summons. This notice matters because it starts the clock on your right to request a hearing and claim exemptions.

Right to hearing: Once you receive notice, you can file a written objection claiming that the amount exceeds the legal limit or that your wages are exempt (Social Security benefits, unemployment compensation, workers' compensation, and public assistance are all exempt from garnishment in Illinois). Filing an objection triggers a court hearing where the creditor must prove the garnishment is proper.

Retaliation prohibition: Illinois law, like federal law, prohibits an employer from firing or disciplining an employee solely because their wages were garnished. 735 ILCS 5/12-818 provides this protection. One garnishment order cannot be the sole basis for termination. Two or more garnishment orders from different creditors may — under limited circumstances and depending on employer policy — be treated differently under Illinois law, but single-garnishment terminations are prohibited.

Child Support Garnishment: Different Rules in Illinois

Child support and spousal maintenance withholding in Illinois operates under federal law (15 U.S.C. § 1673(b)(2)) and the Illinois Income Withholding for Support Act (750 ILCS 28/20(a)), not under the ordinary creditor caps in 735 ILCS 5/12-803. Do not apply the 15% gross rule to child support — the numbers are entirely different.

For child support withholding, federal law allows up to 50% of disposable earnings if the paying parent supports another family (spouse or child from a different relationship). If there is no other family, the cap is 60%. Add 5% to either cap if the parent is more than 12 weeks behind on support — bringing the maximum to 55% or 65% of disposable income.

Illinois's Income Withholding for Support Act implements automatic withholding through employers once a support order is entered. Employers must comply within a specified number of business days of receiving the withholding notice and must prioritize support withholding over any ordinary creditor garnishment if both exist on the same paycheck.

Practical consequence: A parent who already has child support withheld may have almost no remaining wages reachable by an ordinary creditor garnishment, since support withholding takes priority and the 15% gross ceiling is a total cap on ordinary creditor garnishment. The support withholding and the ordinary garnishment cannot together exceed the support percentages or push total deductions past amounts that would leave the worker unable to sustain minimum living requirements under applicable law.

Multiple Creditors: How Illinois Handles the Queue

Illinois caps the total amount garnished from a paycheck at 15% of gross wages, regardless of the number of judgment creditors. Unlike some states that allow each creditor to take their own separate slice, Illinois treats the 15% as a shared ceiling.

Priority is determined by the order in which the employer received the garnishment summons — not the date of the judgment or the size of the debt. The first creditor to serve the employer has first claim on the available 15%. If that first garnishment exhausts the entire cap, subsequent creditors receive nothing until the first judgment is paid in full and that garnishment order terminates.

How subsequent creditors get in line: A creditor who served a garnishment summons while another order is active can request that the employer keep their order on file and begin deductions once the prior garnishment is satisfied. This keeps the creditor's priority position without requiring them to re-apply each time.

Strategic implications for debtors: If you have multiple judgments outstanding, the order in which creditors move matters enormously. A creditor who waits loses priority. Understanding your queue can help you negotiate settlements — a second-priority creditor has strong incentive to settle for less because they may wait years before seeing any payment.

Strategic implications for creditors: Move quickly to serve the garnishment summons on the employer once judgment is entered. Delays allow other creditors to jump ahead.

How to Object: Your Rights Under 735 ILCS 5/12-807

Illinois gives you the right to challenge a wage garnishment if the amount is wrong or your income is legally exempt. The objection process is codified at 735 ILCS 5/12-807 and must be initiated promptly — typically within the time frame specified in the garnishment summons, often around 40 days.

Filing your objection: Submit a written objection to the court where the garnishment was issued. The objection should specify whether you are claiming that the withheld amount exceeds the legal cap, that your wages fall below the protected floor, or that your income is exempt by category.

Exempt income categories in Illinois include: — Social Security benefits (federal exemption under 42 U.S.C. § 407) — Supplemental Security Income (SSI) — Unemployment compensation benefits — Workers' compensation awards — Veterans' benefits — Public assistance payments — Retirement plan distributions (often protected, but analysis is fact-specific)

Once you file an objection, the court schedules a hearing. The creditor bears the burden of showing that the garnishment is authorized and properly calculated. If you are correct that wages fall below the protected floor or that income is exempt, the court must release the garnishment.

Practical tip: If your employer is withholding more than the legal cap, do not wait. File an objection immediately and attach your pay stubs showing gross wages. Courts routinely adjust orders where the math is clear.

Using the Calculator and Official Resources

TheLegalCalc's Illinois Wage Garnishment Calculator at /wage-garnishment-calculator/illinois applies the 735 ILCS 5/12-803 two-prong test to your gross weekly wages. Enter your gross weekly pay, and the calculator shows the maximum a creditor can legally garnish — together with the floor comparison that determines whether your wages are fully protected.

The calculator assumes ordinary private creditor garnishment. It does not calculate child support withholding (which follows different rules) or federal tax levies (which have their own exemption tables). Use it as a planning tool to understand what a creditor can legally reach before attending a court hearing or negotiating a settlement.

Official sources: The full text of 735 ILCS 5/12-803 through 5/12-818 is available at ilga.gov, the Illinois General Assembly's public statute database. For legal representation if you have received a garnishment notice, the Illinois State Bar Association Lawyer Referral Service and Illinois Legal Aid Online (illinoislegalaid.org) offer referrals and free resources.

If wages are being withheld from your paycheck and you have not received a court judgment notice or a garnishment summons from the court, contact the Illinois Department of Labor — unauthorized payroll deductions are a separate wage theft violation with different remedies.
