Some deductions like charitable contributions are conducive to tax fraud. These tax-related events are subject to the utmost IRS scrutiny. Therefore, taxpayers are subject to very detailed rules which require them to produce a specified form of documentation as proof of a viable deduction. If they do not provide the requisite paperwork, then no deduction will be allowed, regardless of the availability of other information that may justify the deduction. Taxpayers that make charitable deductions in excess of $250 and fail to provide specific, detailed documentation to the IRS will have their deductions ultimately disallowed.
