1. 如果是Fidelity, 你到你的賬戶裏去挖,是能夠看到多少是稅前的錢,多少是稅後的錢的。即使不是非得離題,你打電話去問,administrator肯定是有賬可查的。
2. 如果你的錢還是在401K裏,那麽不管before or after tax , 任何distribution 都是pro rata, 按比例發給你。關於哪些錢需要再付稅,Fidelity會告訴你的。
3. 如果不想動稅後的錢,最好的辦法是把401K裏稅後的那部分滾到Roth IRA, 但是啊但是,你必須 take a full distribution of your 401K. You are not allowed to take a distribution of only the after-tax portion. After a full distribution, you can then roll the pre-tax portion to an IRA and the after-tax portion to a Roth IRA. Do not forget, there are RMDs at age 73 for 401K. So take action before the age of 73.
