I don't believe so. Perhaps you should get into contact with your Taxation Department (Where ever you live) and ask them.
Well, for example, donating food to a homeless guy is not tax-deductible.
Whilst donating food to a homeless shelter might be tax-deductible.
I would say that perhaps if you donated to a charitable organization, it MIGHT be tax-deductible. No guarantees though, consult your local government..
I have no idea what you mean by the last sentence lols..In Mass, USA where I live, donating to non profit orginizations is most times deductable. Like if you donate you piece of crap car to an org that takes them, they write you a reciept so you may use that for your taxes. I think you can claim up to a certain amount.
You can also claim losing scratch tickets (lottery tickets) if you have won big $$$, ie $10K. Sick huh?
