Got a bunch of money that you need to spread around to make sure it's all covered by FDIC? If you have more than $100,000 in any one bank, FDIC will not cover above that number.
CDARS lets you register for a system that will automatically spread whatever you're depositing (including CD's and mutual funds) through enough banks to keep the accounts under that limit. And it's free.
I've found many tax guys and investment professionals don't know about it, so I thought I'd share it.
