The One Big Beautiful Bill: What It Actually Changes for Your Taxes

On July 4, 2025, the One Big Beautiful Bill Act was signed into law. For most Americans, this is the most consequential tax legislation since the Tax Cuts and Jobs Act of 2017—and for business owners, it reshapes how you structure, plan, and project your tax liability for years ahead.

Here's what changed, why it matters, and where the planning opportunities are.

The Foundation: TCJA Made Permanent

The most significant thing the bill does isn't introducing something new. It prevents something from disappearing.

The 2017 Tax Cuts and Jobs Act was always a temporary structure—built with expiration dates baked in. Without new legislation, most of those provisions would have sunsetted at the end of 2025, triggering the largest automatic tax increase in decades.

The One Big Beautiful Bill makes those provisions permanent. That means:

• Lower individual income tax rates stay in place indefinitely
• The larger standard deduction doesn't disappear
• The 20% Qualified Business Income (QBI) deduction for pass-through business owners is now a permanent fixture of the tax code

That last point matters significantly for self-employed individuals, LLC owners, and S-Corp operators. The QBI deduction was one of the most powerful planning tools available, and its permanent status changes how you think about business structure over the long term.

What's New: Four Temporary Deductions (2025–2028)

Beyond making existing provisions permanent, the bill introduces several new deductions scheduled to run through 2028. Each comes with income phase-outs and caps—the planning opportunity varies based on your situation.

No Tax on Tips

Workers in industries where tipping is customary can deduct a significant portion of tip income directly from taxable income. Both employees and self-employed individuals in qualifying occupations are eligible, up to an annual cap.

What to know: This isn't a blanket exclusion for all tipped income. The IRS will define which occupations qualify. If your business operates in hospitality, food service, or personal services, this provision may apply.

No Tax on Overtime

Qualifying overtime pay under the Fair Labor Standards Act becomes partially deductible, up to a defined cap—with a higher limit for married couples filing jointly.

What to know: This is a deduction, not a credit. It reduces taxable income rather than providing a dollar-for-dollar reduction in tax owed. The impact depends on your marginal bracket.

Senior Deduction

Taxpayers 65 and older receive an additional above-the-line deduction, phasing out at higher income levels.

What to know: If you're in or approaching this age group, this interacts with your retirement income strategy. The phase-out structure means timing matters.

Auto Loan Interest Deduction

Interest paid on auto loans for vehicles assembled in the United States becomes deductible, up to a defined cap and income threshold.

What to know: This is the first time personal auto loan interest has been deductible since the 1980s. The deduction expires in 2028, which has implications for vehicle purchase timing.

Business-Specific Changes

100% Bonus Depreciation, Restored and Made Permanent

Bonus depreciation—the ability to immediately deduct the full cost of qualifying business assets in the year of purchase—is back at 100% and applies to property placed in service after January 19, 2025.

Under prior law, the bonus depreciation rate had been phasing down year by year. The bill restores full immediate expensing and makes it permanent.

For business owners: This is one of the most direct cash flow tools available. Every qualifying equipment or technology purchase you make this year can be fully deducted against current-year income.

EBITDA-Based Business Interest Deduction Returns

The limitation on deducting business interest was previously calculated on a more restrictive basis (EBIT), which excluded depreciation and amortization from the calculation. The bill restores the more favorable EBITDA standard beginning in 2025.

For capital-intensive businesses carrying debt, this change meaningfully increases the amount of interest that can be deducted.

SALT Cap Raised Significantly

The state and local tax (SALT) deduction cap—previously set at $10,000 since 2017—increases substantially beginning in 2025 and adjusts annually through 2029.

Who benefits most: High-income earners in high-tax states who itemize. If you've been taking the standard deduction because the SALT cap made itemizing unattractive, that calculation may have changed.

What This Means for Planning

The bill's passage doesn't eliminate uncertainty—it shifts where the uncertainty lives.

Several provisions expire in 2028. That creates a four-year planning window, not a permanent solution. For decisions with long-term implications—business structure, retirement contributions, major purchases—you want to be working within a strategy that accounts for what happens when those provisions sunset.

The permanent provisions change the baseline for multi-year projections. With the QBI deduction locked in and bonus depreciation restored, the structural case for certain pass-through entities is stronger than it's been in years.

The deductions that arrived with this bill also require proactive action. They don't apply automatically to every return. Each provision carries eligibility requirements, income thresholds, and qualifying criteria. Waiting until filing season to evaluate them is waiting too long.

The Integrated Perspective

Tax law changes don't happen in isolation from your financial picture. The provisions in this bill touch individual brackets, business deductions, retirement strategy, and asset acquisition decisions simultaneously.

The business owner who understands how bonus depreciation interacts with their QBI deduction—and how both interact with their personal bracket—captures more value than the one who looks at each provision in isolation.

That's the difference between tax filing and tax strategy.

If you want to map how these provisions interact with your specific entity structure and income, that's the work of tax engineering. For business owners who want to capture the full benefit of bonus depreciation and permanent QBI against a unified business-personal picture, wealth preservation addresses the longer-term positioning.
