What legal requirements dictate 401(k) vs Roth IRA contribution limits?

Everence Wealth explains the key differences between 401(k) tax-deferred accounts and Roth IRA tax-free retirement savings.

The Internal Revenue Code (IRC) and subsequent regulations set the legal requirements for both 401(k) and Roth IRA contribution limits. For 401(k) plans, the IRS publishes annual limits for employee elective deferrals, catch-up contributions (for those 50 and over), and the overall contribution limit (including employer contributions). These limits are periodically adjusted for inflation. Employers offering 401(k)s must adhere to ERISA (Employee Retirement Income Security Act) regulations, which mandate fiduciary responsibilities, reporting, and disclosure requirements to plan participants regarding plan operations, investment options, and fees. They also dictate non-discrimination testing to ensure that plans do not disproportionately favor highly compensated employees. For Roth IRAs, the IRS also sets annual contribution limits, which may vary based on the taxpayer's modified adjusted gross income (MAGI). There are specific income thresholds beyond which contributions are phased out or entirely disallowed. Unlike 401(k)s, Roth IRAs do not have employer-sponsored plan administration requirements under ERISA, as they are individual retirement arrangements. However, financial institutions offering Roth IRAs must comply with various banking and securities regulations, anti-money laundering (AML) laws, and customer disclosure rules outlined by bodies like the Securities and Exchange Commission (SEC) and the Financial Industry Regulatory Authority (FINRA). Both account types require meticulous record-keeping for tax purposes, and individuals are legally responsible for ensuring their contributions do not exceed cumulative annual limits across all similar accounts they hold. Violations can lead to penalties, excise taxes, and forced withdrawals of excess contributions.
