回複：稅問題: 公司給付的一小部分day care fee, (w-2 box10)

That part is for figuring out your dependent care credit in Form 1040. Usually there is only $3000 to calculate the credit for dependent care, but if you already have employer benefit like flexible account, the amount will be deduct from $3000 to get your credit, in a word, whatever your option, the maximum is $3000 for one kid in your tax return. If you have more spending for one kid, (>$3000), flexible account has advantage because it allows you put $5000 maximum, does it make sense for you,
