is this your bounced check or one of a client?
if the client's check bounced, your reduce your cash in bank account and also reduce your income account, thereby already claiming it as a loss
and yes the fees are expenses you can deduct
but if these are your personal checks, no
Your question, as phrased, makes no sense.
Only if it's business-related.
business related = you own a business
If you're the one who wrote them, no.
If you're a business, somebody wrote you a bad check, and your bank charged YOU a fee for it, yes.
