Age 70 1/2: Required minimum distributions (RMD) begin for tax-deferred accounts including traditional IRA’s, SEP-IRA’s, and employer plans such as 401(k), 403(b), 457 plans. You can delay the first distribution until April first of the year following the year you turn 70 1/2. However, may not be advisable to delay, because you would need to take a second distribution in that same year.

Note: If you fail to take sufficient RMD, the tax penalty is 50% of the amount that should have been taken.
