A Keogh Plan is a tax deferred pension plan available to self-employed individuals or unincorporated businesses for retirement purposes. A Keogh plan can be set up as either a defined-benefit or defined-contribution plan, although most plans are defined contribution.
The main benefit of a Keogh Plan vs. other retirement plans is that a Keogh Plan has higher contribution limits. The maximum allowable contribution is $53,000. Withdrawals must not be made before 59 ½ years of age and must begin by the age of 70 ½.
