Schedule 1-A is a new tax form designed to consolidate four key OBBBA deductions that can be taken for the first time in 2025. Ultimately these four deductions: the tip deduction, the overtime deduction, the deduction for interest paid on a new car loan, and the senior deduction, appear as a single entry on line 13b of Form 1040. These deductions are phased out at higher income levels, the calculation of which takes place on Schedule 1-A. Accounting and finance professionals who wish to understand the mechanics of the four deductions and how they are expressed on Schedule 1-A and consolidated on Form 1040 would benefit from taking this program.
