Take advantage of catch-up contributions
. Once you're 50 or over, you can contribute thousands more to your 401(k) plan than your younger colleagues. For 2012, you can contribute an additional $5,500 over the annual limit of $17,000, for a total of $22,500. Any employer contribution on top of that is gravy.
Don't stop there. You can also make a $1,000 catch-up contribution to an IRA, for a total contribution of $6,000 in 2012. Unlike with a traditional IRA, you don't have to take annual minimum withdrawals from a Roth once you turn 70 1/2. There are, however, income limits on Roth contributions. You're eligible if your modified adjusted gross income is less than $125,000 ($183,000 if you're married and file jointly).
