When you receive your paycheck, you might notice that your take-home pay is lower than your gross earnings. While payroll taxes like federal income tax and Social Security are commonly discussed, other mandatory payroll deductions can also impact your paycheck. These deductions are required by law in certain circumstances and ensure that funds are allocated appropriately for legal obligations and employee benefits. Understanding these deductions helps you better manage your finances and know what to expect on your pay stub.
Wage Garnishments: When the Law Requires Deductions

Wage garnishments are one of the most significant mandatory payroll deductions outside of taxes. A garnishment is a legal order requiring an employer to withhold a portion of an employee’s wages to pay off a debt. This can happen for several reasons, including:
Unpaid Child Support: If a parent fails to pay court-ordered child support, their wages can be garnished to cover the amount due. Federal and state laws dictate how much can be withheld, ensuring the individual still retains some income.
Unpaid Debts or Loans: Creditors can obtain a court order to garnish wages for unpaid debts, including credit cards, medical bills, or personal loans.
Unpaid Taxes: The IRS or state tax agencies can garnish wages for unpaid tax liabilities without requiring a court order.
Student Loan Defaults: If a federal student loan is in default, the U.S. Department of Education can garnish wages without a court ruling.
Employers are legally required to process wage garnishments according to the court or agency instructions. Employees should receive official notification before garnishments begin and may have legal options to dispute or adjust the amounts withheld.
State Disability Insurance (SDI) Deductions
Some states require employees to contribute to a state disability insurance (SDI) program, which provides short-term disability benefits if an individual is unable to work due to illness, injury, or pregnancy. Currently, states with SDI programs include California, New Jersey, New York, Rhode Island, and Hawaii.
The amount deducted varies by state and is usually a small percentage of wages. Employees can access these benefits if they need temporary financial assistance due to a covered disability. While SDI deductions reduce take-home pay, they offer important protection in case of unexpected medical leave.
State-Mandated Retirement Plans
In recent years, some states have implemented state-sponsored retirement savings programs for employees who do not have access to an employer-sponsored plan, such as a 401(k). These programs—like CalSavers in California and OregonSaves in Oregon—automatically enroll eligible employees, deducting a percentage of their wages unless they choose to opt out.
The goal is to encourage retirement savings for workers in small businesses or industries where employer-sponsored plans are less common. While participation is automatic, employees typically have the flexibility to adjust their contribution rates or opt out entirely.
Tracking Mandatory Payroll Deductions
Since mandatory payroll deductions affect your earnings, it's important to review your pay stub regularly. Employers typically provide a breakdown of these deductions, making it easy to verify accuracy and identify any unexpected withholdings.
While taxes are the most well-known payroll deductions, other mandatory deductions—such as wage garnishments, state disability insurance, and state-mandated retirement contributions—also impact your take-home pay. Understanding these deductions allows you to budget effectively and be proactive in managing your finances. If you ever have questions about a deduction on your paycheck, don’t hesitate to seek clarification from your employer or a financial professional.
