From the  Wall Street Journal.com:
 
Retirees who ignore the annual distributions  they are required to take from their individual retirement accounts  usually run a big risk -- in the form of a 50% excise tax on the amount  they should have withdrawn. But not next year.
On Tuesday, President Bush signed legislation  that suspends the rule requiring older Americans to take withdrawals  from tax-deferred retirement accounts, such as traditional IRAs and  401(k)s.
But there are hitches. The suspension  lasts for just one year, 2009. And while intended to give beaten-down  retirement accounts time to rebound, the new law may also present confusion,  particularly for those just starting to take required withdrawals.
 
"The [existing] rules are confusing  enough," says Ed Slott, an IRA consultant in Rockville Centre,  N.Y. "Now, more people than ever are going to get tripped up."
 
Here are answers to questions about how  the new law will affect taxpayers in 2009 and beyond.
 
Q: How do the existing rules governing  IRA withdrawals work?
A: Those who contribute to tax-deferred  retirement accounts, such as traditional IRAs and 401(k)s, don't pay  income tax on the money they put into these plans. But eventually, Uncle  Sam requires them to take the money out, and pay income taxes in the  process. "The government gives you a tax break when you make your  contributions. When you retire and are presumably in a lower tax bracket,  it wants the tax revenue it deferred," Mr. Slott says.
 
Normally, IRA owners must begin withdrawing  money from these accounts by April 1 of the year after they turn 70½.  That means that someone who turned 70½ in 2008, for example, has until  April 1, 2009, to take his or her first required distribution. To calculate  how much to withdraw, look at your account balance as of the previous  Dec. 31, and then divide that figure by your remaining life expectancy.  (Life-expectancy data can be found in actuarial tables in IRS Publication  590.)
You can always withdraw more. But if  you take less, you will be subject to the 50% penalty. These requirements  also apply to 401(k)s and some other employer-sponsored plans, but not  to defined-benefit pension plans or Roth IRAs. (If you are still working,  you aren't required to take distributions from your current employer's  retirement plan.)
Q: What impact will the new law have?
 
A: The new law suspends required distributions  in 2009. This gives those who can afford to leave their nest eggs alone  a better chance of recovering some of the losses they sustained this  year. Why? "They'll have more dollars working for them in the event  of a stock market rebound," says Elizabeth Drigotas, a principal  at Deloitte Tax.
Unless Congress decides to extend the  moratorium on mandatory distributions, those over age 70½ -- along  with those who have inherited IRAs or 401(k)s -- will be forced to resume  taking withdrawals in 2010.
