You can also deduct donations of goods to Salvation Army or some other charity that you can donate clothes too. I think you can deduct $40.00 per bag of clothing.
You would put your donation on a Schedule A form if filling one out. As I answered on another thread, you would get a receipt from the church. We send ours out quarterly. All the IRS needs to know, is that you didn't get any product for the payment..and that's usually written on the church receipe.
