1. Do tax breaks begin in 2025?

Question: Can taxpayers claim the new senior deduction and the write-offs for tips, overtime and interest on automobile loans, on their 2025 tax returns?

Joy Taylor: Yes, these tax breaks are available for 2025. The so-called “One Big Beautiful Bill” (OBBB) includes four brand new temporary deductions that eligible individuals can claim on their tax returns, depending on their modified adjusted gross income. These are the deductions for up to $25,000 of qualified tips, $12,500 ($25,000 on joint returns) of qualified overtime compensation, $10,000 of interest paid on loans to buy a new vehicle after 2024, and the $6,000 senior tax deduction for each person who is age 65 or older. These write-offs are temporary, first taking effect on 2025 tax returns that you file next year and ending after 2028. They are available to taxpayers who itemize on Schedule A of the Form 1040 and to filers who claim the standard deduction.

2. Are deductions above, or below-the-line?

Question: Are the new senior deduction and the write-offs for tips, overtime and interest on automobile loans “above-the-line” or “below-the-line?”

Joy Taylor: These four deductions, which are available to itemizers and to taxpayers who claim standard deductions, are “below-the-line” deductions, meaning they are subtracted from adjusted gross income (AGI) to arrive at taxable income.

3. Modified AGI and the new tax breaks

Question: The new senior deduction, the $40,000 cap on state and local tax (SALT) deductions, and the deductions for tips, overtime and interest on automobile loans all begin to phase out once modified adjusted gross income (“modified AGI”) exceeds a certain amount. What is the definition of modified AGI for these new tax breaks?

Joy Taylor: Modified AGI is often used by the IRS to determine your eligibility for certain tax benefits or tax breaks or to determine whether you are subject to surtaxes or surcharges. True to the complexity of the federal tax code, the definition of modified AGI often differs, depending on what it is used for.

For purposes of the modified AGI thresholds for taking the five above-described deductions in the OBBB, you begin with your adjusted gross income on line 11 of your Form 1040 and add any foreign earned income exclusion, foreign housing exclusion, and any amounts excluded from gross income because they were received from sources in Puerto Rico or American Samoa.

Note that these tax breaks have different modified AGI threshold amounts:

  • The $40,000 cap on state and local tax deductions claimed on Schedule A of the Form 1040 begins to phase out at modified AGI over $500,000 ($250,000 for married couples who file separate returns).
  • The $6,000 deduction for people age 65 and older ($12,000 on joint returns if each spouse is 65 or older) begins to phase out at modified AGI over $150,000 on joint returns and $75,000 on other returns.
  • The deductions for up to $25,000 of qualified tips and up to $12,500 ($25,000 on joint returns) of qualified overtime compensation begin to phase out at modified AGI over $300,000 on joint returns and $150,000 on other returns.
  • The deduction for up to $10,000 of interest paid on automobile loans begins to phase out at modified AGI over $200,000 on joint returns and $100,000 on other returns.

4. How does the deduction for overtime pay work?

Question: I have heard conflicting reports about the new deduction for overtime pay. What pay can be deducted? Is it the entire amount of overtime pay or just the overtime premium pay? For example, if someone is paid time-and-one-half for overtime, can the taxpayer deduct the full time-and-one-half pay or only the 50% extra amount?

Joy Taylor: The OBBB offers a brand-new deduction for up to $12,500 ($25,000 on joint returns) of qualified overtime compensation. This tax break is available for eligible taxpayers who claim the standard deduction and for those who itemize on Schedule A of the Form 1040. It is a temporary deduction, first taking effect on 2025 tax returns filed next year and ending after 2028. The write-off begins to phase out at modified AGI over $300,000 on joint returns and $150,000 on other returns.

The new statute defines the term “qualified overtime compensation” as overtime paid to an individual under Section 7 of the Fair Labor Standards Act of 1938 that is in excess of the regular rate at which the individual is employed. So that means only the portion above the worker's regular rate qualifies for the deduction (meaning the extra 50% for employees who get one-and-one-half their regular pay rate for overtime pay). Employers must report overtime pay on Form W-2 (or Form 1099 for contractors).

This new tax break requires guidance from the IRS, and it is expected that the guidance will describe in more detail exactly what pay is considered qualified overtime compensation. In the meantime, I have included below an excerpt from a report by the staff of the bipartisan congressional Joint Committee on Taxation, that describes the Fair Labor Standards Act of 1938 for this purpose.
