ERISA does not require any employer to establish a retirement plan. It only requires that those who establish plans must meet certain minimum standards.The Plan Administrator may prescribe such uniform and nondiscriminatory rules as it deems appropriate to carry out the terms of this Plan Section 3.01(C). For guidance on what may cause a 403(b) plan to be subject to ERISA, please consult the Department of Labor's rules. The requirement to file Form 5500 is not new for ERISA 403(b) plans; however, new rules have greatly expanded the amount of information that must be reported. The IRS recently released Revenue Ruling 20117 (the "Ruling") to clarify the requirements for employers terminating 403(b) plans. Plans that do not fall under Title I of ERISA do not have to comply with ERISA requirements relating to participation standards, minimum coverage, vesting,. 403(b) plan terminations require advanced planning and awareness of the legal requirements and tax consequences. ERISA rules can be complicated. As such, they may deter some small business owners from setting up retirement accounts for their employees.
