If your goal is a legitimate tax deduction, then you must be giving to a qualified organization. Also, you cannot deduct contributions made to specific individuals, political organizations and candidates. See IRS Publication 526, Charitable Contributions, for rules on what constitutes a qualified organization.
Charitable contributions are only deductible if you itemize deductions on Form 1040, Schedule A (PDF), Itemized Deductions. To be deductible, you must make charitable contributions to qualified organizations. Payments to individuals are never deductible. To determine if the organization that you have contributed to qualifies as a charitable organization for income tax deduction purposes, refer to our Exempt Organizations Select Check tool.
