What can be a consequence of not properly documenting a gift for donor's tax purposes?

When a gift is not properly documented for donor's tax purposes, one key consequence is that higher penalties or disallowance of exemptions may occur. Accurate record-keeping is vital in substantiating the value of the gift and ensuring that it aligns with tax regulations. If there is inadequate documentation, tax authorities may challenge the reported values and question the legitimacy of the reported exemptions or deductions.

This situation creates a risk of incurring penalties for failing to meet the necessary reporting requirements. Additionally, if the documentation is insufficient, the IRS may disallow certain deductions or exemptions entirely, leading to an increased tax liability for the donor. In this respect, proper documentation serves not just as a protective measure for the donor, ensuring compliance and minimizing penalties or audits, it is also critical in accurately reflecting the nature and value of the gift for tax purposes.

The consequences outlined in the other options are less likely or not applicable in the context of inadequate gift documentation. For example, invalidating the gift or higher tax rates for the recipient are not common repercussions directly tied to documentation failures.
