Explaining 401(k) Risk and Compliance

Companies who offer 401(k)s have additional responsibilities for insuring the plan against risk, complying with IRS guidelines for non-discrimination, and reporting on the plan.

  • A fidelity bond, which protects the company from liability due to fraud, must be purchased by each company with a 401(k) plan. Contact Support to purchase a fidelity bond through Zenefits' Business Insurance team.
  • Each plan must have a fiduciary who will be responsible for making decisions about the plan. 
  • Each year, 401(k) plans are subject to non-discrimination testing to ensure that no employees are disproportionately favored by the plan. 
  • These tests, which include the ADP, ACP, and Top-heavy tests, primarily examine the participation of Key and Highly-Compensated Employees (HCEs).
  • Employers who make contributions to employee 401(k)s through safe harbor plans (and observe other administrative duties) are usually exempt from the non-discrimination tests.
  • All 401(k) plan providers must file Form 5500, which reports various information about the plan, including its assets, participants, and financial activities.
