大概是你付的钱不够吧？ 必须至少为去年的 100% 或今年的 90%，以较小者为准。注意，如果你今年欠的多得多，

你最好将去年的百分比提高到 110%。这是以前朋友的经历。 110%比100%更安全。我想这是为了向国税局表明你在计算中犯了一个无心的错误，并尽力纠正它。

我们就遇到这种情况，今年的税是去年的两倍！我把这个 01/15 金额提高到了去年的 125%。 目前还没收到IRS的消息。 我们是三月初提交的。Paper filing (we cannot use electronic filing).  I also paid the bulk of the remaining tax by ACH thru IRS account, leaving less than $200 balance that was paid with a check mailed together with the paper filing - the check is to ENSURE IRS receive our paper filing - once they cashed the check that meant they had received the paper return package.  Any delay process IS their problem.
