This article will shed light on the payroll deductions that are mandatory by law and answer common questions related to them.

Payroll Deductions Required by Law:

1. Federal Income Tax (FIT):
Federal income tax is a mandatory deduction at the federal level. Employers are responsible for withholding the appropriate amount from each employee’s paycheck based on their tax bracket and the information provided on Form W-4.

2. State Income Tax (SIT):
In states with an income tax, employers must withhold state income tax from employees’ wages. The amount withheld varies based on the employee’s earnings and the state’s tax rates.

3. Social Security Tax (FICA):
The Federal Insurance Contributions Act (FICA) mandates the deduction of Social Security taxes. Both employers and employees contribute a percentage of the employee’s wages to fund Social Security benefits.

4. Medicare Tax:
Similar to Social Security tax, Medicare tax is a mandatory deduction under FICA. It funds the Medicare program, which provides health insurance for individuals aged 65 and older.

5. Unemployment Insurance (UI) Tax:
Employers must contribute to the state’s unemployment insurance program, which provides temporary financial assistance to employees who lose their jobs. The amount is determined based on the employer’s payroll and the state’s tax rate.

For employees who have defaulted on their federal student loans, wage garnishments may be imposed by the Department of Education. Employers must comply with such orders and withhold the specified amount from the employee’s wages.
