401K

A plan where you can save money toward your retirement on a tax-deferred basis – that is, you don't pay federal or state income taxes on your savings or their investment earnings until you withdraw the money at retirement. A 401(k) is a retirement savings plan sponsored by an employer. It lets workers save and invest a piece of their paycheck before taxes are taken out.

 

IRA

An Individual Retirement Account (IRA) is a type of savings account that is designed to help you save for retirement and offers many tax advantages.  Unlike the 401K, the IRA can be set up without help of your employer.

 

403B

A 403(b) plan is a U.S. tax-advantaged retirement savings plan available for public education organizations, some non-profit employers (only Internal Revenue Code 501(c)(3) organizations), cooperative hospital service organizations, and self-employed ministers in the United States. 403(b) plans are also referred to as a tax-sheltered annuity or tax-deferred annuity.
