2025 Schedule 1-A Form and Instructions

What Is Form 1040 Schedule 1-A?

Form 1040 Schedule 1-A, Additional Deductions, is used to claim certain additional deductions that can't be entered directly on Form 1040. These deductions are often described as no tax on tips, no tax on overtime, no tax on car loan interest, and the enhanced deduction for seniors. On the form itself, the IRS uses more specific terms such as qualified tips, qualified overtime compensation, and qualified passenger vehicle loan interest. The 2025 Schedule 1-A Instructions are not published as a separate booklet. Instead, you will need to read the Schedule 1-A line item instructions found inside the general Form 1040 instructions booklet.

The total additional deductions from Schedule 1-A, line 38, are entered on Form 1040 or Form 1040-SR, line 13b. Taxpayers filing Form 1040-NR enter the same total on Form 1040-NR, line 13c. This is different from Schedule 1, which reports additional income and adjustments to income before adjusted gross income is calculated. Schedule 1-A deductions are claimed later on page 2 of Form 1040, in the Tax and Credits section, directly after the standard deduction or itemized deductions line.

Form 1040 Schedule 1-A, Additional Deductions, is a new schedule for tax year 2025. Schedule 1-A was created for the new additional deductions that begin with 2025 returns. It is attached to Form 1040, Form 1040-SR, or Form 1040-NR when one or more of these deductions applies.
