The special safe harbor is a schedule of uniform minimum default automatic contribution percentages starting at 3% and gradually increases each year an employee participates. Under a QACA: an employer must make a minimum of either: a matching contribution of: 100% of an employee's contribution up to 1% of compensation and a 50% matching contribution for the employee's contributions above 1% of compensation and up to 6% of compensation; or a nonelective contribution of 3% of compensation to all participants, including those who choose not to contribute to the plan. employees must be 100% vested in the employer's matching or nonelective contributions by two years of service. A QACA may not distribute the required employer contributions due to an employee's financial hardship. Return to FAQs
