In general, any voluntarily-established employee retirement and health plans offered by private-sector employers are subject to the rules and regulations of ERISA. While ERISA doesn't require employers to provide certain benefits, it mandates their plans meet certain standards.
Types of prohibited transactions Fiduciary self-dealing transactions occur when a fiduciary (such as a plan administrator or trustee) uses plan income or assets for their own interest. Self-dealing can lead to conflicts of interest and is prohibited under ERISA.
In general, ERISA does not cover plans established or maintained by governmental entities, churches for their employees, or plans which are maintained solely to comply with applicable workers compensation, unemployment or disability laws.
ERISA prohibits cross trades, the exchange of assets between two accounts without going through a public market. There have been numerous exemption requests motivated by a desire to reduce transaction costs. Mutual funds are permitted to cross trade under Rule 17a-7.
In a defined benefit plan, an employer can require that employees have 5 years of service in order to become 100 percent vested in the employer funded benefits (called cliff vesting).
ERISA restricts certain actions related to how benefit plans are designed and administered. For example, it limits the types of investments that retirement plans can make, imposes fiduciary duties on plan administrators, and mandates specific reporting and disclosure requirements.
Common types of employer-sponsored retirement accounts that fall under ERISA include 401(k) plans, pensions, deferred-compensation plans, and profit-sharing plans. In addition, ERISA laws don't apply to simplified employee pension (SEP) IRAs or other IRAs.
Traditional IRAs share many of the tax advantages of plans like 401(k)s but are not offered by employers and are not qualified plans.
Individual Retirement Accounts (IRA's) are not governed by ERISA and do not receive similar protection. IRA protection is based upon state law.
The Employee Retirement Income Security Act (ERISA) covers most employer-sponsored retirement plans including SIMPLE individual retirement accounts (IRAs). SIMPLE IRAs were designed to make it easy for businesses with fewer than 100 employees to set up a tax-advantaged retirement plan for their workers.
