CTR 15 day filing deadline

Could someone clarify the 15 day filing deadline for CTRs. If the 15th day falls on the weekend, does the reg. allow for the CTR to be mailed on the following Monday or does it need to be mailed on the Friday preceeding the weekend. If so, where exactly in the reg. does it state such. thank you

The instructions on the back of the CTR say "to file this CTR by the 15th calenday day after the day of the transaction...". No where that I can see do the instructions say anything about if the 15th day falls on a weekend you can mail your CTR on the following Monday. Always err on the side of caution and mail your CTR earlier than day 15. If need be, send it overnight express.

Do CTRs need to be MAILED by the 15th day, or received by the IRS by the 15th day? I always thought they needed to be received by the 15th day, but reading this post has me confused.
Thanks for your help.

I always send mine within the first week so I don't have to worry about cutting it that close.

CTR's need to be filed no later than the 15th day.

However, FinCEN says that the CTR's need to be RECEIVED no later than the 19th day...or it's considered late. At least that is what we found out during our last exam.

Okay how about this situation-----say, the date of transaction is 03/28/2005 and the date of signature (presumed to also be the date filed) is 04/12/2005....that is exactly 15 calendar days. Could this be criticized by the examiners?

I don't like living on the edge. We require our CTRs to be mailed by the 10th calendar day. But to answer your question, the CTR instructions state your CTR must be "filed by the 15th calendar day after the day of transaction." File to me means in the mail.

we mail (US Postal Service) ours on the 15th day and have not been critized by KPMG, OCC, or E&Y
