I have a small NJ charity that supports homeless mentally challenged people. I received an anonymous donation of a winning lottery ticket. Can the charity collect the winnings? For taxes, how do I report this? Does the charity have to pay taxes on this? Is this considered unrelated income which would be taxable?
Yes, the charity can collect the winnings.
The type of charity is important for everything else, but mainly for the person that donated it and when. Such as was it a winning ticket when the organization received it.
For the charity there will most likely only be the net investment tax which is a type of tax that doesn't exist outside of the non-profit world, and any "income" or "lottery" taxes withheld can come back. Its pretty awesome. Get tax advice from a non-profit lawyer.
If your charity is not properly registered then you will have to pay the full taxes.
