What the One Big Beautiful Bill Act Means for Taxpayers, Businesses

A Sweeping Tax Overhaul

By Tim Provost, CPA

In a dramatic display of legislative determination, the U.S. Congress passed, and President Trump signed into law, a sweeping tax reform package on July 4. Though stripped of its campaign-era title for procedural reasons, the One Big Beautiful Bill Act represents one of the most comprehensive overhauls of the U.S. tax code since the Tax Cuts and Jobs Act (TCJA) of 2017.

Packed with both solidified extensions of soon-to-expire provisions and a host of new reforms aimed at individuals and businesses, the legislation reshapes the tax landscape for years to come. It also dramatically curtails green energy tax incentives to offset the substantial cost of these reforms, estimated to exceed $5 trillion over a decade.

Making TCJA Permanent

At its core, the bill cements many key provisions of the TCJA that were set to expire at the end of 2025. These include the maintenance of reduced individual income tax brackets (10% to 37%), the higher standard deduction, the elimination of personal exemptions, and the expanded alternative minimum tax thresholds.

The final legislation increases the standard deduction beginning in 2025, setting it at $31,500 for joint filers, $23,625 for heads of household, and $15,750 for single or married individuals filing separately. These figures will continue to be indexed for inflation.

The child tax credit is permanently increased to $2,200 per child, with inflation adjustments and a refundable portion of $1,700 for 2025.

The act also preserves the expanded estate tax exemption at $15 million (indexed for inflation) and makes permanent several itemized deduction limits and changes to the mortgage interest deduction, which will now include mortgage insurance premiums.

“In a move that drastically shifts federal energy policy, the act eliminates or shortens a range of green energy tax credits introduced in the Inflation Reduction Act.”

Tax Relief for Workers and Families

Among the most headline-grabbing provisions are new deductions designed to benefit middle-income earners in specific professions:

• A new tax deduction of up to $25,000 is available for tip income received in specific occupations (excluding highly compensated employees). The deduction begins to phase out at $150,000 of modified adjusted gross income for individuals and $300,000 for joint filers. This deduction is available through 2028.

• Overtime compensation is now partially shielded from taxation, with a deduction capped at $12,500 per taxpayer and income limits similar to those for tips.

• Seniors age 65 and over are eligible for a bonus standard deduction of $6,000 through 2028, subject to income phaseouts.

SALT Cap Expansion, Expiration

Long a point of contention, the state and local tax (SALT) deduction cap sees a temporary reprieve. The cap is lifted from $10,000 to $40,000 in 2025, increasing slightly each year through 2029, before reverting to the original limit in 2030. However, phaseouts apply for taxpayers with high incomes, starting at a modified adjusted gross income of $500,000.

Business Provisions Made Permanent

For businesses, the bill makes several long-advocated provisions permanent:

• It reinstates 100% bonus depreciation for qualified property placed in service after Jan. 19, 2025 and makes it permanent. The bill further includes expanded eligibility for manufacturing property and broader asset classes.

• The bill permanently reinstates full expensing of domestic research and experimental (R&E) costs from 2025. Small business taxpayers with average annual gross receipts of $31 million or less may even retroactively apply this change back to 2022 through amended returns. Taxpayers who previously capitalized R&E costs after Dec. 31, 2021, and before Jan. 1, 2025, may elect to accelerate the remaining deductions for such expenditures over a one-year period or ratably over a two-year period.

• Though the House bill proposed increasing the qualified business income (Sec. 199A) deduction to 23%, the final law keeps it at 20% while expanding phase-out thresholds. The deduction is now permanent.

• The maximum small business expensing (Sec. 179) deduction is increased to $2.5 million, with a phase-out beginning at $4 million of property acquisition.

IRS Reform and International Tax Tweaks

The Act terminates the IRS Direct File program, reallocating funds to study a public-private partnership model for free tax filing solutions.

International tax changes include renaming and modifying deductions:

• FDII and GILTI are renamed to FDDEI (foreign-derived deduction eligible income) and NCTI (net CFC tested income), respectively, with corresponding deduction percentages reduced slightly from current levels.

• The base erosion and anti-abuse tax rate is stabilized at 10.5% instead of the scheduled increase to 12.5%.

“Businesses, especially those involved in capital investment and research, will benefit from enhanced expensing rules and the permanence of deductions that had previously been temporary.”

Green Energy Rollbacks: A Major Offset

In a move that drastically shifts federal energy policy, the act eliminates or shortens a range of green energy tax credits introduced in the Inflation Reduction Act.

Clean vehicle credits, residential clean energy credits, alternative fuel infrastructure credits, and energy-efficient home credits are terminated after Dec. 31, 2025 (or slightly later in the Senate compromise).

Notably, the New Markets Tax Credit, supporting low-income investment, was preserved and even made permanent, a lone holdover in an otherwise sweeping repeal of energy-related incentives.

Final Thoughts

The One Big Beautiful Bill Act legislation brings a significant degree of clarity and continuity to the federal tax code. By making many provisions of the TCJA permanent and introducing new deductions targeted at workers and families, the law offers both simplification and expanded relief for a broad spectrum of taxpayers.

At the same time, the reduction or elimination of several green energy incentives reflects a reprioritization of fiscal resources aimed at offsetting the cost of these reforms. Businesses, especially those involved in capital investment and research, will benefit from enhanced expensing rules and the permanence of deductions that had previously been temporary.

As the new provisions take effect, taxpayers, advisors, and financial professionals will need to evaluate how the changes impact planning strategies and compliance obligations in both the near and long terms. Continued guidance from the IRS and Treasury will be critical to implementing the new rules effectively and ensuring that both individuals and organizations can make informed decisions under the updated tax framework.
