Most of the time, ATM fees are not claimable, as those are not inherently business expenses. Transfer fees are a similar situation.
Here is when you would have an exception:
1. The fee is BOTH assessed to your business (ministry) account AND
2. The fee is associated with a purely business (ministry) transaction.
(If the ATM or transfer fee is for you to take out money for your expenses, then that would not qualify as a business expense.)
Of course, if the fee IS claimable, then you would be responsible to keep those receipts, as usual. Any receipt greater than $75 would still be sent to FBMI as well.
