For spouses filing jointly, the standard deduction for 2025 is $31,500 + $1,600 for each of you who is 65 or older. There is also a $6,000 senior deduction for each of you 65 or older when your modified adjusted gross income is $150,000 or less. It is NOT part of the standard deduction. Rather it is computed separately on Schedule 1-a line 37 and that flows to line 13b on your 1040
