May I deduct as charitable contributions expenses that I incur on behalf of a charitable organization that are not reimbursed?
Per IRS Publication 1771:
If a donor makes a single contribution of $250 or more in the form of unreimbursed expenses, e.g., out-of-pocket transportation expenses incurred in order to perform donated services for an organization, then the donor must obtain a written acknowledgment from the organization containing:
a description of the services provided by the donor
a statement of whether or not the organization provided goods or services in return for the contribution
a description and good faith estimate of the value of goods or services, if any, that an organization provided in return for the contribution
a statement that goods or services, if any, that an organization provided in return for the contribution consisted entirely of intangible religious benefits (described earlier in this publication), if that was the case.
In addition, a donor must maintain adequate records of the unreimbursed expenses. See Publication 526, Charitable Contributions, for a description of records that will substantiate a donor’s contribution deductions.Example of an unreimbursed expense: A chosen representative to an annual convention of a charitable organization purchases an airline ticket to travel to the convention. The organization does not reimburse the delegate for the $500 ticket. The representative should keep a record of the expenditure, such as a copy of the ticket. The representative should obtain from the organization a description of the services that the representative provided and a statement that the representative received no goods or services from the organization.
