Illinois Wage Garnishment Calculator

Work out the maximum a judgment creditor can deduct from your paycheck in Illinois. The calculator runs both statutory tests — 15% of gross weekly wages and the 45× minimum wage floor — and applies whichever protects more of your pay.

The Illinois wage deduction rule

Illinois protects wages more aggressively than most states. Section 12-803 of the Code of Civil Procedure sets the ceiling as the lesser of two figures, calculated on a weekly basis:

735 ILCS 5/12-803, in plain terms

Test A — 15% of gross weekly wages.
Test B — the amount by which weekly disposable earnings exceed 45 times the greater of the federal or Illinois minimum wage, which is 45 × $15.00 = $675.
The creditor gets whichever is smaller. If disposable earnings are $675 a week or less, the creditor gets nothing.

Notice which figure each test uses. Test A works from gross pay; Test B works from disposable earnings, defined as gross minus legally required withholding — income tax and FICA only. Voluntary deductions such as a 401(k) contribution or a health premium do not reduce disposable earnings, however much they reduce the money in your account.

Worked examples

Weekly figures. Required withholding is federal and Illinois income tax plus FICA.

$1,200$253.28$946.72$180.00$271.72$180.00
$1,500$349.19$1,150.81$225.00$475.81$225.00

The pattern is worth internalizing: at lower incomes the 45× floor does the protecting and the creditor gets nothing; as pay rises there is a crossover a little above $1,000 gross a week, beyond which the flat 15% becomes the binding limit.

How a wage deduction proceeding works in Illinois

  1. The creditor sues and wins. No garnishment is possible for ordinary consumer debt until there is a judgment.
  2. A wage deduction summons is issued and served on your employer, along with a wage deduction notice sent to you.
  3. Your employer answers under oath, stating your wages and calculating the deduction, and begins withholding.
  4. You may claim exemptions on or before the return date. This is the step people miss, and the deadline is real.
  5. A deduction order is entered and the employer forwards the money until the judgment, plus interest and costs, is satisfied.

Illinois judgments accrue interest while they are outstanding — 5% a year on a consumer-debt judgment of $25,000 or less, and 9% otherwise — so a garnishment at the statutory maximum on a large judgment can run for years. That is often the strongest practical argument for negotiating a settlement instead.

Child support and other priority orders

Child support does not use the 15% rule. Illinois follows the federal Consumer Credit Protection Act percentages, applied to disposable earnings:

SituationMaximum of disposable earnings
Supporting another spouse or child50%
Supporting another spouse or child, arrears over 12 weeks55%
Not supporting another spouse or child60%
Not supporting another spouse or child, arrears over 12 weeks65%

Priority matters when several orders compete for the same paycheck. Child support comes first, then federal tax levies, then state levies, then ordinary creditor garnishments. If a support order already consumes the available wages, an ordinary creditor may receive nothing at all.

Income a creditor cannot reach

  • Social Security retirement, disability and SSI payments
  • Veterans' benefits
  • Unemployment compensation
  • Workers' compensation benefits
  • Public assistance and TANF
  • Most pension and retirement plan distributions
  • Life insurance proceeds and annuity payments in many circumstances

These protections can be lost through commingling. Once an exempt payment is deposited alongside wages in a general bank account, tracing it becomes your burden. Keeping exempt income in a separate account is the simplest way to preserve the protection.

A student loan or tax levy follows different rules

Federal student loan administrative wage garnishment takes up to 15% of disposable pay without a court judgment. IRS levies use exemption tables based on filing status and dependents rather than a percentage. The Illinois Department of Revenue can also levy wages for unpaid state tax. None of these are limited by the 735 ILCS 5/12-803 formula, so the calculator above does not model them.

What to do if your wages are being garnished

Check first whether the amount is even correct — employers calculate wage deductions by hand more often than you would expect, and the gross-versus-disposable distinction is a frequent source of error. Run your own figures through the calculator above and compare against the pay stub.

Then consider the underlying debt. If you were never properly served with the original lawsuit, the judgment may be vulnerable. If the income is exempt, file the claim of exemption within the deadline. If neither applies, a direct payment arrangement with the creditor usually costs less than the statutory maximum, because creditors discount for certainty. Free help is available from Illinois Legal Aid Online and from the legal aid organization serving your county.

If a garnishment is already reducing your pay, the Illinois paycheck calculator can show what remains after tax and the deduction together, which makes budgeting around it considerably easier.

People also ask about wage garnishment in Illinois

An ordinary judgment creditor may take the lesser of two amounts: 15% of your gross weekly wages, or the amount by which your disposable earnings exceed 45 times the minimum wage. With the Illinois minimum wage at $15.00, that protected floor is $675 a week. Whichever test produces the smaller number is what the employer must deduct — and if your disposable earnings are $675 a week or less, nothing can be taken at all.
