I searched google and got hits for several charities that say they are tax deductible. I'm sure they are, as all clothing, houseware, etc are when you donate to Goodwill. I did it all the time. What you need is to take pictures of the items (proof) and get a receipt. We use Turbo Tax so I'm not sure how you'd do it otherwise, but they have a section for donations and even an itemized list of the value of things. Say, a pair of jeans are $30, top is $20, etc. You can look into it. If it's a legitimate charity then they must give you a receipt if you want it.
