Not sure if we need to amend these:
1.Amount incorrect by $10.00 (we were under by $10,00 on amount of transaction).
2. Part II amount was correct. Re: part I amount, part of the amount was transposed
3. First name spelled incorrectly; the rest of the CTR is correct.

Thanks!

You should file amended CTRs for each of those. There isn't a "that's good enough for gummit work" option in the CTR instructions.

The only folks who can say an amendment is unnecessary work at FinCEN. There are no published "close enough" rules.

Well, that is clear. Thanks folks.

Would a full name versus shortened version be amendment necessary (for example, our customer database says his name is Christopher, but we filed with Chris), or if our customer record for a business does not include the punctuation that the SOS has (ABC, Inc.versus ABC Inc)? I know it would be easiest to amend, but for the future I am curious about training my staff, versus making the changes in our core system so the names always match the SOS if possible.

A variation in punctuation has no effect on the data provided. I suggest that the name on the account should match that found on the identification and the name on the report should match both.

Would you amend a CTR that is correct as far as it goes but did not include the middle initial of one client?

I have too much on my plate to worry about something like that but I am curious what others think.

Ken's answer above is the only answer that anyone not working for FinCEN can give.

I am only answering this because I have had the situation with the middle initial and called FinCEN and was told that I did not have to amend the CTR. Now the flip side of that coin is if you call and get someone different than I talked to you might get another answer. If you call FinCEN, I would document their name, time and date and what was said. If possible, we are able to put notes on our CTRs and if you are able, I would do that.

The middle initial is not a required field on the CTR form. If you have it, you should include it. If you did not have it at the time of filing, and then later obtain the middle initial, I would not spend the time to track that and refile because it wasn't available at the time of filing. Just my opinion.
