Your employer may have a reason for taking money from your paycheck, but it does not necessarily make the deduction legal. The law in Illinois places limits on when an employer can deduct wages you’ve already earned, and it’s important to understand your rights.
Not every deduction is unlawful. Employers can generally make deductions required by law, such as taxes or deductions made for your benefit when properly authorized. Wage deductions may also result from a valid wage assignment or court order.
A prior agreement may not be enough
Illinois law requires an employee’s express written authorization that is freely given at the time of the deduction when an employer relies on that consent to withhold wages. A provision in an employee handbook or a general workplace policy may not give an employer unlimited authority to take money from your paycheck.
This distinction can matter if your employer deducts money for a cash shortage, damaged company property, an alleged overpayment or another work-related expense. The circumstances surrounding the deduction, including when and how you gave consent, can affect whether the withholding complies with the law.
The steps to take if you have concerns
Before assuming your employer had the right to take your money, you should look at both the purpose of the deduction and whether you actually authorized it. Start by checking your pay stub and identifying exactly what was withheld and why.
Next, review any agreement, policy or communication your employer provided about the deduction, and keep copies of records that may help establish when you were notified or asked to authorize it. If the reason is unclear, ask your employer to explain the deduction in writing. Keep a record of their response along with any documents relating to the deduction.
Seeking experienced legal guidance can help you determine whether the deduction complied with Illinois law and whether you may have a claim for wages that were improperly withheld.
