If you're enrolled in an employee retirement plan, such as a 401(k) or pension plan, you're a plan participant with certain rights and protections guaranteed by federal rules.
The plan in which you participate may be subject to administration and investment rules set by the Employee Retirement Income Security Act (ERISA).
As a participant, you have the right to certain information about your plan, such as a summary plan description, which outlines how it works. You also have the right to see copies of the tax reporting form that your plan must file with the IRS each year (Form 5500), as well as statements showing your estimated retirement benefits. If you have problems with your plan, you also have the right to bring claims against it.
