Filing considerations
Below are some considerations about the new Schedule 1-A.
Qualified tips
In Part II, Schedule 1-A discusses the tax deduction to eliminate taxes on qualified tips. In the Form 1040 instructions, the IRS provides a detailed explanation on qualified tips.
According to the IRS, qualified tips are tips that you received from customers or, as an employee, through a tip-sharing arrangement in an occupation that customarily and regularly received tips on or before December 31, 2024.
Qualified tips are tips that are:
- Cash tips,
- Paid voluntarily,
- Not the subject of negotiation, and
- Determined by the customer or payor.
The IRS website contains a list of occupations that customarily and regularly received tips on or before December 31, 2024.

Why do you think that this will give the wrong results? The senior deduction is a $6,000 per person deduction with a phaseout that begins at $75,000 MAGI ($150,000 for married couples filing jointly).
Specifically, from the Public Law 119-21 text: In the case of any taxpayer for any taxable year, the $6,000 amount in clause
(i) shall be reduced (but not below zero) by 6 percent of so much of the taxpayer’s modified adjusted gross income as exceeds $75,000 ($150,000 in the case of a joint return).
