Missouri vs. Illinois Garnishment Laws

The one-line bottom line: Missouri generally follows the federal ceiling of 25% of disposable earnings (with a far more protective 10% cap for the head of a family), while Illinois limits wage deduction to the lesser of 15% of gross wages or the amount of disposable earnings exceeding 45 times the Illinois minimum wage — a state minimum higher than the federal one — which usually shields more of an Illinois worker's pay than Missouri law shields a Missouri worker's.

How much of your wages can be taken

The central difference between the two states is the wage-garnishment cap, and it is worth understanding precisely because the formulas are not the same.

In Missouri, wage garnishment runs through Chapter 525 of the Revised Statutes, and the amount a creditor can take tracks the federal ceiling set by the Consumer Credit Protection Act. Under that federal law (15 U.S.C. § 1673, a federal statute that applies nationwide), an ordinary creditor may garnish the lesser of 25% of the debtor's weekly disposable earnings or the amount by which those disposable earnings exceed 30 times the federal minimum wage. "Disposable earnings" means gross pay minus legally required deductions — taxes, Social Security, and Medicare — not voluntary ones like retirement or health premiums. For most Missouri workers who are not heads of a family, the practical cap is 25% of disposable earnings.

Illinois takes a structurally different approach. Under the Illinois wage-deduction statute (735 ILCS 5/12-801 and the sections that follow), a creditor may garnish only the lesser of 15% of the debtor's gross weekly wages or the amount by which the debtor's disposable earnings exceed 45 times the Illinois minimum wage. Two features make this generally more protective than the federal floor that Missouri uses. First, the percentage is lower — 15% rather than 25%. Second, the protected floor is keyed to 45 times the Illinois minimum wage, and because Illinois sets its own minimum wage well above the federal level, that floor shields a larger band of low and moderate earnings entirely. (The exact dollar figures shift whenever the Illinois minimum wage changes, so always confirm the current minimum wage before running numbers.) The net effect is that, on the same paycheck, an Illinois garnishment will usually reach less than a Missouri garnishment would for a non-head-of-family debtor.

The head-of-family difference

Missouri adds a protection that Illinois does not mirror in the same form. Under Missouri's wage-garnishment rule, a debtor who is the head of a family — generally a person who provides more than half the support of a spouse, child, or other dependent — is subject to a much lower cap, commonly described as 10% of disposable earnings rather than the standard 25%. For a Missouri debtor who supports a household, that single status can cut a wage garnishment by more than half, and a debtor who believes the status applies should claim it promptly and in writing because the protection is not automatic.

Illinois has no separate "head of family" rule of this kind. A debtor supporting dependents in Illinois does not get a special reduced percentage on that basis. But the comparison is not that simple: the Illinois formula already starts from a lower 15% ceiling and a higher minimum-wage floor, shielding a meaningful share of wages for everyone. So the two states reach protection by different routes — Missouri through a head-of-family carve-out on top of the federal 25% ceiling, Illinois through a lower across-the-board formula. A Missouri head of family may be more protected than an Illinois worker; a Missouri debtor who is not will typically be less protected.

Exempt income and property

Both states recognize that certain income and property should be off-limits to creditors entirely, and here the two systems overlap more than they differ — largely because the strongest protections come from federal law.

Federally protected benefit income is shielded in both Missouri and Illinois. Social Security retirement, SSDI, and SSI benefits, along with many veterans' benefits, certain pensions, and unemployment compensation, are generally protected from ordinary creditors no matter which state's garnishment law applies. When those benefits are direct-deposited, federal banking rules require a garnished bank to review the account and automatically protect a recent look-back of deposited federal benefits. That protection is imperfect in both states — it misses benefits received by paper check or commingled with other money — so the burden can fall on the debtor to assert the exemption and prove the source.

Each state also layers its own statutory exemptions on top of the federal protections. In Missouri, those exemptions live in Chapter 513 and include a modest general "wildcard" amount along with specific exemptions for categories such as household goods and tools of a trade. Illinois provides its own set of personal-property exemptions, including a wildcard amount and protections for specified categories of property, through its exemption statutes. The categories and dollar amounts differ between the states and change over time, so a debtor claiming a state exemption should confirm the current figures for the state whose law governs. The practical point for both creditors and debtors is the same in either state: exempt funds can be protected, but the protection often has to be claimed actively rather than assumed.

The garnishment process and your right to object

The procedural backbone is similar in both states. Neither Missouri nor Illinois lets an ordinary creditor garnish anything until it has sued the debtor, won a money judgment, and then obtained a court order — a writ of garnishment in Missouri, a wage-deduction or non-wage garnishment summons in Illinois — directed at a third party. That third party, called the garnishee, is typically the debtor's employer or bank. Service on the garnishee is what legally freezes or begins withholding the property, and the garnishee must then answer the court, stating whether it holds the debtor's wages or funds and how much. In both states, a garnishee that is properly served but ignores the order risks being held liable to the creditor for the amount it should have withheld.

The debtor's right to object also exists in both states, and in both it is time-sensitive. A Missouri debtor can file a claim of exemption or motion to quash with the issuing court — arguing the funds are exempt benefit income, that the head-of-family cap applies, that a Chapter 513 exemption covers them, or that the creditor miscalculated. An Illinois debtor receives an exemption notice with the garnishment papers and can request a hearing to claim exemptions or challenge the amount withheld under the 735 ILCS 5/12-801 framework. In either state, if the underlying judgment was a default entered without proper service, the debtor may move to set it aside — and if the judgment falls, the garnishment falls with it. Deadlines are short in both states, so a debtor who wants to object should act immediately, with proof of the funds' source and of any dependents.

Bank-account versus wage garnishment

Both states distinguish between garnishing wages and garnishing a bank account, and the distinction works similarly across the line. A wage garnishment reaches only a capped percentage of each paycheck over time — 25% or 10% in Missouri, generally 15% or the formula floor in Illinois — and a continuing wage garnishment keeps collecting across successive pay periods until the judgment, interest, and costs are satisfied. A bank-account garnishment is different in kind: rather than skimming a percentage, it can freeze the entire non-exempt balance in the account as of the moment the bank is served. That makes account garnishment faster and more powerful for creditors and more alarming for debtors in both states, which is precisely why the exemption rules matter most there.

The percentage caps that protect wages do not carry over to protect a bank balance once wages have been deposited. In both Missouri and Illinois, money sitting in an account is generally reachable up to the amount owed unless a specific exemption — federal benefit protection, a state wildcard, or another statutory category — shields it. The practical guidance is identical on both sides of the river: a debtor who relies on protected benefit income should keep it in a separate account, avoid commingling it with ordinary wages or gifts, and be ready to prove the source of every protected dollar, because the automatic bank-level protection may not catch everything.

Key differences at a glance

• Wage cap formula. Missouri follows the federal CCPA ceiling: the lesser of 25% of disposable earnings or the amount above 30 times the federal minimum wage. Illinois caps deduction at the lesser of 15% of gross wages or the amount of disposable earnings above 45 times the Illinois minimum wage.
• Baseline percentage. Missouri's ordinary cap is 25%; Illinois's is 15% — generally more protective on the same income.
• Minimum-wage floor. Missouri's federal floor uses 30 times the federal minimum wage; Illinois uses 45 times the (higher) Illinois minimum wage, shielding a larger band of earnings. Confirm the current minimum wage in each state before calculating.
• Head-of-family rule. Missouri offers a much lower cap (commonly described as 10% of disposable earnings) for a head of a family. Illinois has no equivalent head-of-family reduction, but its lower baseline formula already shields more for everyone.
• Judgment first. Both states require a money judgment and a court order before an ordinary creditor can garnish; neither allows ordinary self-help garnishment.
• Exempt benefits. Social Security, SSI, SSDI, and many veterans' and public benefits are protected in both states, largely under federal law, with imperfect automatic bank protection in each.
• State exemptions. Missouri's are in Chapter 513; Illinois has its own personal-property and wildcard exemptions. Categories and amounts differ and change over time.
• Bank accounts. In both states a bank garnishment can reach the full non-exempt balance at once; the wage percentage caps do not protect deposited funds.

Which state's law applies?

For wage garnishment, the state whose law governs generally follows where the debtor works and is paid — that is, where the employer that issues the paycheck is located and withholds the wages. A debtor employed in Missouri is typically subject to the Missouri caps under Chapter 525, while a debtor employed in Illinois is typically subject to the Illinois deduction limits under 735 ILCS 5/12-801, regardless of which state the debtor lives in. That is why a cross-border commuter in the St. Louis metro can find that the river, not their home address, determines how much of a paycheck a creditor can reach.

Several wrinkles complicate this in the bistate region. The court that entered the judgment may sit in one state while the employer is in the other, which can require the creditor to pursue garnishment where the garnishee can be served — often the state where the employer does business. Large employers with operations on both sides of the line, and remote or hybrid arrangements, can blur where wages are "earned" for garnishment purposes. And a judgment from one state generally must be recognized or registered in the other before it can be enforced there. Because these jurisdictional questions can flip which percentage cap applies and therefore how much money is at stake, both creditors and debtors should confirm, for their specific facts, which state's garnishment law actually controls before relying on either set of rules.

When to talk to a lawyer

Garnishment is procedural, deadline-driven, and — in the bistate region — complicated by the question of which state's law applies, so getting advice early is often worthwhile. A debtor whose wages or bank account have been garnished and who believes the funds are exempt, who qualifies as a Missouri head of family, who thinks more than the legal cap is being taken, or who never received notice of the underlying lawsuit has time-sensitive options that are easy to lose by waiting. A creditor holding a judgment that needs to be enforced across the state line, or who must identify the right garnishee and serve the correct court order, likewise benefits from confirming the procedure before acting. A qualified attorney licensed in the relevant state can determine which state's law governs, calculate the correct withholding, evaluate exemptions, and meet the deadlines that decide these disputes.
