IRS Distributions,   Early  IRA Withdrawals    10% Additional Tax
Question: How do I calculate the minimum amount that must be withdrawn from my IRA after age 70 1/2?
Answer: Chapter 1 of Publication 590, Individual Retirement Arrangements (IRAs), gives a complete explanation of how to calculate this amount.
As a general rule, follow these guidelines:


The minimum distribution for each year is computed by dividing the IRA account balance at the close of business December 31 of the preceding year by the life expectancy.
The life expectancy is determined by using one of three tables found in IRS Publication 590. You will find the applicable tables below:
Table I will be is used by beneficiaries when there is a sole owner.
Table II will be used for use by owners who have spouses who are more than 10 years younger.
Table III is generally for use by unmarried owners and owners who have spouses who are not more than 10 years younger and owners whose spouses are not sole beneficiaries.
Note that federal lawmakers waived the 2009 minimum distribution requirement and, as a result minimum distributions for tax year 2009 are not required. Call us for any questions, or check the IRS. Gov website.
