What is the minimum amount of support expenses required for claiming a grandmother as a dependent?

To claim someone as a dependent on your tax return, you must provide over half of their total support for the year. For a grandmother to qualify as a dependent under the rules for support, her total support must be calculated, which includes expenses like food, shelter, clothing, medical care, and other necessities.

The correct answer is based on the tax law stipulating that to claim a relative as a dependent, the taxpayer must supply more than half of the dependent's total support expenses. Therefore, if total support is calculated at $13,000, you would need to provide at least $13,001 to satisfy the legal requirement of aiding more than half.

When considering other amounts, they exceed the threshold needed to qualify as the minimum required for this scenario, as they imply unnecessary amounts that would not affect the eligibility to claim a dependent given that the threshold is set higher than what is needed. This context illustrates that only the minimum of $13,001 meets the requirements for dependency, making it the right choice.
