While wage earners have limited tax levers, they can optimize taxable income through three primary categories.
Pre-tax payroll items are excluded from Box 1 of Form W-2, avoiding both income and FICA taxes. These include:
Above-the-line adjustments reduce Adjusted Gross Income (AGI) regardless of whether you itemize or claim the standard deduction. These statutory deductions include:
Itemized deductions only reduce taxable income if their total exceeds the standard deduction ($16,100 single, $32,200 joint in 2026). Primary itemized deductions include:
The TCJA suspended, and OBBBA made permanent, the deduction for unreimbursed employee business expenses under IRC §67(g). Employees must seek reimbursement through an employer-sponsored accountable plan (section “Operational Deductions and Family Employment”). Narrow exceptions survive for Armed Forces reservists, fee-basis government officials, qualified performing artists, and workers with impairment-related expenses.
Clean Vehicle Credits Repealed. The clean vehicle credits under IRC §30D (new electric vehicles) and IRC §25E (used electric vehicles), historically worth up to $7,500 and $4,000 respectively, were repealed by the OBBBA effective September 30, 2025. No federal credit is available for vehicles delivered after that date. The only vehicle-related lever left is the car loan interest deduction below — and it is far weaker. A credit is a dollar-for-dollar reduction of tax; a deduction merely reduces taxable income. For a filer in the 37% bracket, the maximum $10,000 interest deduction is worth $3,700, against the $7,500 the repealed credit delivered outright.
Car Loan Interest Deduction. Amended by the OBBBA under IRC §163(h), “Interest”, interest paid on a loan for a new, personally owned vehicle is deductible above-the-line for tax years 2025 through 2028. To qualify:
The deduction is limited to a maximum of $10,000 of interest per year.
The vehicle must be new, weigh less than 14,000 pounds, and have undergone final assembly in the United States. Plant locations can be verified using the NHTSA VIN Decoder tool.
The loan must be originated after December 31, 2024, and secured by the vehicle. Leases do not qualify.
The taxpayer must enter the Vehicle Identification Number (VIN) on Form 1040. Lenders issue interest statements matching Form 1098.
This deduction phases out rapidly. The phase-out begins at a Modified Adjusted Gross Income (MAGI) of $100,000 for single filers and $200,000 for married couples filing jointly. The deduction is reduced by 20 cents for every dollar earned above these limits, disappearing entirely at $150,000 (single) and $300,000 (joint).
Deductions for Tips and Overtime. Under IRC §224, “Qualified tips” and IRC §225, “Qualified overtime compensation” as enacted by the OBBBA, two temporary deductions are available for tax years 2025 through 2028:
Workers in customary tip industries may deduct up to $25,000 of tip income. The deduction phases out for MAGI exceeding $150,000 ($300,000 joint) at a rate of $100 for every $1,000 of excess income.
Employees may deduct the premium portion (the 50% premium of time-and-a-half pay) required by the Fair Labor Standards Act (FLSA), up to $12,500 ($25,000 joint). The same $150,000/$300,000 phase-out applies.
While exempt from federal income tax via this above-the-line deduction, these earnings remain subject to FICA taxes and are reported on Form W-2.
Non-Qualified Deferred Compensation (NQDC). For corporate executives and highly compensated employees earning well above retirement plan contribution limits, NQDC plans governed by IRC §409A offer a significant tax deferral lever. NQDC allows you to defer a percentage of your salary, bonus, or commissions before taxes. Unlike qualified retirement plans, there is no statutory limit on NQDC contributions. The deferred funds grow tax-deferred and are paid out on a predetermined schedule (e.g., at retirement or on a specific future date) when you may be in a lower tax bracket. However, NQDC plans carry risk: the deferred compensation is an unsecured promise from the employer and is typically held in a rabbi trust (an irrevocable trust designed to hold deferred compensation assets, which remains subject to the company’s creditors in bankruptcy).
