You forfeit any money in the account that you don't use, which means you'll need to take extra care when calculating your yearly expenses. This is easy with childcare costs because you typically pay a fixed amount each week or month. As for medical expenses, if you find that you haven't used all the money at year's end, you can always order another pair of eyeglasses or stock up on any prescription drugs that you take regularly. Even forfeiting a small amount of money is not so bad when you balance it against the tax savings.
Keep in mind that you can't claim the childcare tax credit for any daycare expenses that you pay out of a flexible spending account. This means you'll need to make a choice. The tax credit is equal to only 20% of your expenses up to $2,400 for one child or $4,800 for two (rising to $3,000 and $6,000, respectively, in 2002). The FSA is worth your tax bracket times $5,000, assuming you pay that much. If you're in the 27% tax bracket and have two children, the childcare tax credit would be worth $1,000 ($5,000 x .20 = $1,000). The FSA would be worth $1,350 ($5,000 x .27 = $1,350). An FSA is typically established before the start of the calendar year, while the childcare tax credit is not used until you file your tax return 15 months later. If you don't get around to signing up for the FSA in time, you can always claim the credit. But rather than letting procrastination be your guide, estimate next year's income and expenses so you can make the choice that will give you the most tax savings.
