Employees can elect to contribute to qualified plans on a pretax basis via withholdings from their salaries. Money invested in a qualified plan can grow tax-free.
Plan administrators are allowed, though not obligated, to issue loans to employees who contribute to qualified plans. These loans enable employees to borrow cash from their own retirement funds. Early withdrawals (those made before the plan beneficiary reaches age 59 1/2) from qualified plans are typically subject to tax penalties, with some narrow exceptions.
It's important to note that there are other types of retirement plans that offer tax benefits similar to those of qualified plans, such as traditional and Roth IRAs (individual retirement accounts). Because these plans are used by individuals to save for retirement rather than established by employers in accordance with IRS and ERISA rules, they are not considered qualified.
However, traditional IRAs and Roth IRAs do come with tax advantages, including tax-free growth and other favorable tax treatments. Contributions to traditional IRAs are tax-deductible, and withdrawals from Roth IRAs are tax-free.
