There is a larger standard deduction if the taxpayer and/or spouse is age 65 or older, or blind. IRS Form 1040 U.S. Individual Income Tax Return, Page 1 will indicate if there are additional amounts to include in the standard deduction.
The amount of the additional standard deduction is based on your filing status.
For tax year 2019, age 65 for the additional standard deduction is defined as being born before January 2, 1955.
