Overview of the One Big Beautiful Bill Act (OBBB)
The One Big Beautiful Bill Act (OBBB), enacted in July 2025, introduces significant and wide-ranging changes to the U.S. tax system, with a particular emphasis on immigration status and eligibility requirements. While the law preserves many familiar provisions of the Tax Cuts and Jobs Act, it also modifies deductions, credits, and filing rules that affect individuals, families, and businesses.
Bonus depreciation restored and expanded: Implications for businesses
The return of 100% bonus depreciation means that capital investments—whether in machinery, equipment, or qualifying facilities—can be deducted in full in the year they are placed in service. This can significantly reduce taxable income and improve after-tax cash flow, freeing up capital for reinvestment or other strategic uses.
The new provision for qualified production property is significant for manufacturers, refiners, and producers.
New Above-the-Line Deductions
The OBBB introduces several new above-the-line deductions, allowing taxpayers to reduce adjusted gross income even if they claim the standard deduction. These provisions are designed to provide targeted relief but include income-based phaseouts that limit benefits for higher earners.
Car Loan Interest
Taxpayers may deduct interest on qualified vehicle loans of up to $10,000, provided the vehicle is new and purchased for personal (non-commercial) use. Lease payments are excluded, and the deduction phases out for taxpayers with modified adjusted gross income above $100,000 ($200,000 for joint filers).
Qualified Tip Income
Income earned from tips may be deducted up to $25,000 for taxpayers working in eligible occupations, such as food service, hospitality, and entertainment. This deduction phases out for taxpayers with MAGI above $150,000 ($300,000 for joint filers).
Overtime Pay
Taxpayers earning overtime compensation may deduct the portion of overtime pay that exceeds their regular rate, up to $12,500. This benefit also phases out at higher income levels, following the same MAGI thresholds as the tip income deduction.
New Senior Deduction
The OBBB introduces a new above-the-line deduction of up to $6,000 for taxpayers aged 65 and older, reducing taxable income for qualifying seniors.
Changes for Immigrant Filers
The Act imposes significant restrictions on tax benefits based on immigration status. Many deductions—including new above-the-line deductions—are limited to U.S. citizens and lawful permanent residents. Taxpayers using ITINs face additional scrutiny, delayed refunds, and increased audit risk.
Mixed-status households are particularly affected. Couples consisting of a U.S. citizen and a non–lawful permanent resident must often file separately to preserve eligibility, which can result in higher overall tax liability and the loss of credits such as the Earned Income Tax Credit.
Looking Ahead
The OBBB extends several provisions of the Tax Cuts and Jobs Act through 2027, including current marginal tax rates, the higher standard deduction, and expanded child tax credits. At the same time, it tightens eligibility standards and increases compliance complexity—especially for immigrant and mixed-status families.
Overall, the OBBB represents the most significant overhaul of the tax code in years, offering meaningful benefits to eligible taxpayers while introducing new layers of complexity tied to immigration status. Careful planning and professional guidance are essential to navigate these changes accurately and effectively.
