没遇过,但建议以下--如果欠税的话
1. 赶紧再寄一次,减低被罚的时间
2. 写一分信,解释原因
3. copy 所有的文件,包括有邮戳的信封,以便以后证明最初是按时 file 的
4. 留一份银行户口结余的 print out,证明 file returns 当日有足够的钱来支付欠税
5. 把以上文件一起寄回 IRS
IRS is pretty reasonable and hope will understand the situation and forgive
you on the mix up. but you need to do it ASAP and show good faith. no
guarantee it will work, ok? :p
