Key point. Charitable contribution deductions for contributions of noncash property are subject to various substantiation requirements. Failure to comply with these requirements can result in a loss of any deduction, even if there is no doubt that a contribution was made.

The United States Tax Court upheld the IRS's denial of a $65 million charitable contribution deduction because the written acknowledgment issued by the donee charity was not "contemporaneous" as required by the tax code. On its 2007 tax return, a partnership claimed a charitable contribution deduction of $65 million. In order to substantiate a charitable contribution deduction of $250 or more, a taxpayer must secure and maintain in its files a "contemporaneous written acknowledgment" (CWA) from the donee organization. IRC 170(f)(8)(A). The CWA must state (among other things) whether the donee provided the donor with any goods or services in exchange for the gift. IRC 170(f)(8)(B)(ii).
