The proper way to complete the CTR would actually depend on who is getting the benefit of the cash withdrawal from the business account. If it is for the benefit of the business, such as for petty cash, then the business should be shown in Part 1 Section A with the business owner shown on page 2, Part 1 Section A. If this is the case the simpler way to complete the CTR would be to show the owner on page 1, the business on page 2, check 1 b and c, and check box e in Section B.
If, on the other hand, you know that the owner benefitted from both withdrawals, you would only show him ad dgp indicated.
