Welcome to the site. I'm PDtax, and will be helping you today. The answer is probably yes, but there are some additional questions I'd ask before I could say yes. And, it's a tax deduction, not a tax credit, that may be in play.
If you are operating the soup kitchen, do you use a charitable organization, or are you doing this yourself?
Are you a member of the ministry or clergy?
I am operating it with two other people, but none of us are associated with a charity organization or nonprofit. I am also not a member of the church.
Are you paid at all for your efforts?
Then I would say you could claim a charitable donation for the cost of the food. Save your receipts, and keep records of your event to support the deduction.
OK...and just to clarify, it doesn't matter that I reside in a different state than the event is held, correct?
no, state of residence won't matter.
OK, thanks so much. That was very helpful!
