[DoninGA]

If you are age 65 or older and meet the requirement, the additional deduction is automatically added on your federal tax return.

Standard deductions for 2025

Single - $15.750 add $2,000 if age 65 or older

Married Filing Jointly - $31,500 add $1,600 for each spouse age 65 or older
Head of Household - $23,625 add $2,000 if age 65 or older

New Bonus Standard Deduction (OBBB):
An additional $6,000 deduction for taxpayers 65 and older.
This is per eligible individual, meaning a married couple both over 65 could get $12,000.
Important: This bonus deduction is temporary, lasting from 2025 through 2028.
Income limitations: It phases out for taxpayers with modified adjusted gross income over $75,000 for single filers and $150,000 for joint filers.

The amount is calculated on Schedule 1-A, Part V, with that amount flowing to Form 1040 Line 13b

A new, temporary additional deduction of $6,000 for those aged 65 and older (or $12,000 for a married couple if both qualify) is available for tax years 2025 through 2028. The deduction begins to phase out at income greater than $75,000 and $150,000 if you’re married filing jointly. This is in addition to the standard deduction or itemized deductions. 

The senior deduction is automatically calculated by TurboTax based on the dates of birth you entered for each spouse.

The senior additional deduction appears on line 37 of Schedule 1-A of your form 1040, with that amount flowing to line 13b of your form 1040.
