Passing money through a different account to avoid cash pay-in fees
Let me do the math. .6% * (not large) = really tiny. Since "not large" = "small" , etc.  I suggest that even a small chance that you need to explain this to anyone in the future is a sign to avoid the risk. Yes, there are times that it's illegal. A real estate office may not deposit escrow funds into anything but a segregated escrow account.  In your case, even if legal, it messes up 'the books' and can cost you more in grief than the 'tiny amount' saves you in cash.
Below is an instruction that describes a task. Write a response that appropriately completes the request.
