any donation over $25, you need to have a receipt, and apprasial for large non-cash donations. You need receipts to support moving expenses deduction given that you met the requirements to take this deduction (commute would otherwise increase by 50miles or more, and you stay around for 52 weeks after moving or equivelent. etc) You don't submit those receipts with your return, but need to be able to provide them in the case of an audit. And keep them for 7 years.
