Q: When I do my IRA required minimum distribution I take some extra money out and move it to a taxable account. Good idea or bad idea? Thanks – Bill Faye, Rockville, MD

A: After years of accumulating money for retirement, figuring out what to do with “extra” money withdrawn from your IRA accounts seems like a nice problem to have. But required minimum distributions, or RMDs, can be tricky.

First, a bit of background on managing RMDs. These withdrawals are a requirement under IRS rules, since Uncle Sam wants to collect the taxes you’ve deferred on contributions to your IRAs or 401(k)s. You must take your distribution by April 1st of the year you turn 70 ½; subsequent RMDs are due by December 31st each year. If you don’t take the distribution, you’ll pay a 50% tax penalty in addition to regular income tax on the amount that should have been withdrawn.

The size of your required withdrawal depends on your age and the account balance. (You can find the details on the IRS website here.) If you’re over 59 ½, you can take out higher amounts than the minimum required, but the excess withdrawals don’t count toward your future distributions. Still, by managing your IRAs the right way, you can preserve more of your portfolio and possibly reduce taxes, says Mary Pucciarelli, a financial advisor with MetLife Premier Client Group.

For those fortunate enough to hold more than one IRA, you must calculate the withdrawal amount based on all your accounts. But you can take the money out of any combination of the IRAs you hold. This flexibility means you can make strategic withdrawals. Say you have an IRA with a big exposure to stocks and the market is down. In that scenario, you might want to pull money from another account that isn’t so stock heavy, so you're not selling investments at a low point.

You can minimize RMDs by converting one or more of your traditional IRAs to a Roth IRA. Roths don’t have minimum distribution requirements, so you can choose when and how much money you take out. More importantly, you don’t pay taxes on the withdrawals and neither will your heirs if you leave it to them. You will owe taxes on the amount you convert. To get the full benefit of the conversion, consider this move only if you can pay that bill with money outside your IRA. Many investors choose to make the move after they've retired and their tax bill is lower. Pucciarelli suggests doing the conversion over time so you can avoid a big tax bill in one year.

You could avoid paying taxes on your RMD by making a qualified charitable contribution directly from your IRA to a charity. The tax provision expired last year but Congress has extended the rule through 2014 and President Obama is expected to sign it.

As for the extra money you've withdrawn, it's fine to stash it in a taxable account. If you have sufficient cash on hand for living expenses, you can opt for longer-term investments, such as bond or stock funds. But be sure your investments suit your financial goals. “You don’t want to throw your asset allocation out of whack when you move the money,” says Pucciarelli. Consider a tax-efficient option, such as an index stock fund or muni bond fund. That way, Uncle Sam won't take another big tax bite out of your returns.

Update: This story was changed to reflect the Senate passing a bill to extend the IRS rule through 2014 allowing the direct rollover of an IRA’s required minimum distribution to a charity.
