Which age qualifies for an additional amount in the standard deduction for a taxpayer?

An additional amount in the standard deduction is granted to taxpayers who are 65 years old or older. This provision is designed to provide extra tax relief to seniors, recognizing that they may have additional financial burdens in retirement. Therefore, the correct answer is based on the fact that turning 65 qualifies a taxpayer for this additional deduction.

Taxpayers under the age of 65 do not receive this enhancement to their standard deduction, making options that suggest ages below 65, such as 60, not applicable. The same applies to ages above 65; while they may qualify for the additional amount as well, the specific threshold for the additional deduction begins at age 65. Thus, the focus is on that age for the initial qualification.
