You’ve spent years building your business. Every decision, every investment, every late night has been aimed at creating something valuable—not just for today, but for your future and your family’s legacy. But when major tax legislation passes, do you really understand how it affects what you’ve built? More importantly, do you know whether you’re positioned to take full advantage of new opportunities, or if you’re unknowingly leaving value on the table?
The One Big Beautiful Bill Act, signed into law on July 4, 2025, represents the most significant overhaul of U.S. federal tax policy since 2017. While the headlines focus on percentages and policy jargon, the real story is what this means for your business valuation, your exit strategy, and your ability to transfer wealth to the next generation. For many business owners, navigating these complex changes feels overwhelming—especially when you’re already focused on running and growing your company.
We understand. Staying current with tax legislation while managing daily operations, strategic planning, and growth initiatives isn’t realistic for most business owners. That’s why having experienced advisors who can translate policy changes into actionable strategies for your specific situation is critical. At HBK CPAs & Consultants, we’ve been helping business owners navigate major tax legislation for decades. As a Top 50 accounting firm with specialized expertise in business valuation and strategic planning, we’ve guided hundreds of businesses through significant transitions—and we’re here to help you understand what OBBBA means for your company’s value and your financial future.
Let’s break down the provisions that matter most to you and your business.
1. Bonus Depreciation: Accelerating Your Cash Flow
One of OBBBA’s cornerstone provisions is the permanent reinstatement of 100% bonus depreciation for qualified property. Under the TCJA, bonus depreciation was scheduled to phase down gradually (80% in 2023, 60% in 2024, and so forth). OBBBA eliminates that sunset and ensures businesses can continue to fully expense qualifying property in the year it is placed in service.
Notably, OBBBA also expands eligibility to include certain categories of real property, particularly manufacturing-related improvements, creating new opportunities for industrial businesses to accelerate deductions.
What This Means for Your Business Value
From a valuation standpoint, bonus depreciation accelerates the timing of tax deductions, effectively boosting near-term after-tax cash flow. Since the value of a business is tied to the present value of future free cash flows, this provision increases enterprise value for capital-intensive firms.
If you’re considering selling your business or bringing on investors, 100% bonus depreciation has a positive impact on post-transaction cash flow, especially for asset-intensive businesses. Consequently, deal flow, transaction volume, and valuation multiples have the potential to increase.
2. Section 179 Expensing: Immediate Benefits for Small and Midsize Businesses
OBBBA expands the thresholds and eligible property under Section 179, which allows small and midsize businesses to immediately deduct the full purchase price of certain assets, rather than depreciate them over time.
What This Means for Your Business Value
While the impact is smaller in scale compared to bonus depreciation, Section 179 changes have a similar directional effect—enhancing near-term cash flow and improving the economics of M&A transactions structured as asset sales.
3. Research and Development Expensing: A Game-Changer for Innovation
Under the TCJA, companies were required to capitalize and amortize R&D expenses over five years (15 years for foreign research). OBBBA reverses this policy, allowing immediate expensing of domestic R&D costs once again.
What This Means for Your Business Value
This change materially benefits R&D-intensive industries—such as technology, pharmaceuticals, and advanced manufacturing—by improving short-term cash flow and increasing after-tax returns on innovation.

4. Tax Loss Carryforwards and Interest Deductibility: Better Leverage for Growth
OBBBA also redefines adjusted taxable income (ATI) used in calculating the limitation on the deductibility of business interest expense. This new definition allows additional interest expense to be deducted in the current period, rather than carried forward.
What This Means for Your Business Value
Greater interest deductibility improves near-term free cash flow, especially for leveraged or private equity-backed companies. For businesses with existing net operating losses (NOLs), OBBBA’s adjustments to carryforward utilization rules increase the value of deferred tax assets, which should be explicitly modeled in any valuation.
These provisions also affect capital structure assumptions—since increased deductibility can enhance the tax efficiency of debt financing, marginally lowering the weighted average cost of capital (WACC) used to discount future earnings to the present.
5. Section 199A: Qualified Business Income Deduction Made Permanent
Under the TCJA, the 20% Qualified Business Income (QBI) deduction for pass-through entities was scheduled to expire after 2025. OBBBA makes this deduction permanent, thereby avoiding a significant increase in effective tax rates for partnerships, S corporations, and LLCs.
What This Means for Your Business Value
This permanence introduces greater tax predictability for pass-through entities and materially affects normalized after-tax earnings.
For valuation purposes, the permanence of Section 199A removes the need to factor in an increase in pass-through tax burdens in the near-term. It may also influence entity structure decisions, as the relative advantage of pass-through taxation is preserved compared to the corporate tax regime.
6. Qualified Small Business Stock (QSBS): Enhanced Capital Gains Exclusion
OBBBA enhances the Qualified Small Business Stock (QSBS) provision under Section 1202 by raising the capital gains exclusion limit to $15 million and introducing a sliding-scale benefit based on the holding period:
- 5 years: 100% exclusion
- 4 years: 75% exclusion
- 3 years: 50% exclusion
What This Means for Your Business Value
The expanded QSBS exclusion significantly increases after-tax investor returns in qualifying private companies, potentially spurring capital formation in the lower middle market.
From a valuation perspective, the expected after-tax proceeds to investors are higher, which can reduce required rates of return or increase observed transaction multiples for eligible firms.
7. Estate Planning and the Lifetime Exclusion: Protecting Your Legacy
OBBBA increases the lifetime estate and gift tax exclusion to $15 million per individual, indexed for inflation, and designates it as permanent. While “permanent” is a legislative term of art rather than a guarantee, the expanded exclusion opens substantial opportunities for wealth transfer planning.
Why This Matters for Your Family’s Future
High-net-worth individuals and business owners may wish to use at least part of the expanded exclusion now, particularly to transfer highly appreciating assets such as minority interests in private companies. These transfers can lock in current valuations and shift future appreciation outside the taxable estate.
8. Understanding “Permanent” Policy: Act While the Window Is Open
While OBBBA’s provisions are framed as permanent, tax policy is inherently political. Business owners and investors understand that future legislation can reverse even long-term statutes. As a result, many are acting swiftly to capitalize on these provisions while they remain intact.
From a valuation standpoint, this creates a two-speed environment:
In the short term, cash flow and valuation multiples may rise due to enhanced after-tax earnings and favorable deal structures. Over time, as the market adjusts and policy risk reemerges, these benefits could normalize or reverse depending on future congressional action.
Picture Your Business with Strategic Clarity
Imagine knowing exactly how these tax changes affect your company’s value. Imagine having a clear roadmap for when to make capital investments, how to structure your exit, and how to transfer wealth to the next generation with confidence. You’re not reacting to policy changes—you’re ahead of them, making informed decisions that protect and grow what you’ve built.
That’s what strategic guidance looks like. You feel secure knowing your business structure is optimized for current tax laws. You’re empowered to have meaningful conversations with potential buyers or investors because you understand your true enterprise value. Most importantly, you have peace of mind knowing you’re not leaving money on the table or missing critical planning opportunities.
Without understanding these provisions and how they apply to your unique situation, you risk missing opportunities to enhance your business value, optimize your tax position, and protect your legacy. Generic advice won’t cut it—you need advisors who understand your industry, your goals, and how to translate complex legislation into actionable strategy.
