On July 4, 2025, President Trump signed the One Big Beautiful Bill Act into law. For business owners, it delivers both permanent enhancements to depreciation and expensing and expanded tax credits, along with a significantly broader capital‑gains exclusion for certain C Corporation stock.


1. Permanent Bonus Depreciation & Increased Expensing

  • 100 Percent Bonus Depreciation Becomes Permanent
    Under current law, bonus depreciation phases down 20 percent per year after 2023. The new law makes 100 percent immediate expensing permanent for qualified property placed in service after January 19, 2025. This provision may allow eligible businesses to reduce taxable income in the year of acquisition, depending on their specific circumstances.
  • Higher Section 179 Expensing Threshold
    The maximum annual Section 179 deduction rises from $1 million to $2.5 million, with the phase‑out threshold increasing from $2.5 million of equipment purchases to $4 million (indexed for inflation after 2025). This change may enable more small to mid-sized firms to expense the full cost of qualifying assets in the year purchased.


2. Expanded Research, Workforce & Energy Credits

  • R&D Expense Deduction Restored
    Previously, domestic research costs had to amortize over five years. The Act reinstates immediate expensing of R&D outlays and allows eligible small businesses (≤ $31 million in gross receipts) to elect retroactive deductions for 2022–2024. This may improve cash flow for innovation-focused firms.  
  • Business Interest Deduction Cap Raised
    For 2025 and beyond, “adjusted taxable income” for purposes of the interest‑expense limitation will exclude depreciation, amortization, and depletion. This change may allow businesses with high capital costs to deduct a larger share of interest in the current year.
  • Paid Family & Medical Leave Credit Made Permanent
    The credit, which covers up to 25 percent of wages paid to employees on qualified leave, now becomes permanent. It also expands to include family‑leave insurance premiums, potentially lowering the net cost of offering leave benefits.
  • Other Notable Credit Extensions & Increases
  • 50 percent deduction for business‑meal expenses remains permanent.
  • Enhanced advanced‑manufacturing investment credit rises from 25 percent to 30 percent for property placed in service after December 31, 2025.
  • Employer child‑care credit increases to $500,000 (40 percent of expenses) and adds a small‑employer credit up to $600,000 (50 percent of expenses).
  • Student‑loan assistance exclusion becomes permanent and indexed for inflation.
  • Paid Overtime Tax Credit of up to $12,500 ($25,000 joint filers) introduced.
  • New Markets Tax Credit and certain rural‑loan interest exclusions are extended or introduced.


3. Enhanced Qualified Small Business Stock (QSBS) Exclusion

According to Husch Blackwell, the Act confirms three major updates to IRC § 1202 that may influence your choice of entity selection and capital‑gains planning (Husch Blackwell):


  1. Tiered Holding‑Period Exclusions
  • ≥ 3 years held → 50 percent exclusion
  • ≥ 4 years held → 75 percent exclusion
  • ≥ 5 years held → 100 percent exclusion
  1. Higher Per‑Issuer Cap
  • The exclusion limit increases from the greater of $10 million or 10× basis to $15 million, with annual inflation adjustments.
  1. Increased Gross‑Asset Threshold
  • Qualifying C Corps may now have up to $75 million in assets (up from $50 million), indexed for inflation.


These changes may make C Corporation status more attractive for startups and growth companies planning liquidity events three or more years out. However, the benefits depend on a variety of factors, including timing, structure, and exit strategy.

The Buttonwood Agreement: Where American Finance Took Root — and Why Our Name Exists The Buttonwood Agreement was a compact signed on May 17, 1792, by 24 stockbrokers and merchants beneath a buttonwood tree at 68 Wall Street in New York City. It established the rules of organized securities trading in America and laid the foundation for what would become the New York Stock Exchange. Buttonwood Financial Group takes its name directly from this founding moment; as a daily commitment to the integrity, transparency, and long-term thinking those original brokers put on paper. What was the Buttonwood Agreement, and why it still matters The Buttonwood Agreement came at a moment of crisis. The Panic of 1792, America's first speculative bubble and market collapse, had shattered public confidence in capital markets. Prominent financiers defaulted. Prices fell. Investors panicked. Alexander Hamilton worked to stabilize the system, but the lasting fix came from the professionals themselves. On May 17, 1792, 24 brokers gathered under a buttonwood (sycamore) tree outside 68 Wall Street and signed a two-sentence agreement: they would deal only with each other, charge a standard commission of one-quarter percent, and give preference to fellow signers in all negotiations. Simple. But the effect was transformative. By agreeing to hold a higher standard collectively, they rebuilt confidence in the market itself. The Buttonwood Agreement is widely regarded as the founding document of the New York Stock Exchange and of organized American finance. Why Buttonwood Financial Group carries this name Boutique wealth management firms are built on process and trust. When we named our firm Buttonwood Financial Group, the choice wasn't aesthetic; it was philosophical. Our name is a daily accountability measure; a reminder that the values those brokers signed onto in 1792 — integrity, structure, and responsibility — are exactly the values our clients deserve today. The families and individuals we serve aren't looking for surface answers and financial products. They're looking for an experienced team that has been tested across market conditions, that communicates honestly, and that approaches every client relationship from a fiduciary capacity in a long-term commitment. That's what an established boutique wealth management firm looks like in practice. What experience really means Experience in this industry isn't about credentials alone. It means you have been present with clients through market downturns and periods of uncertainty. You have worked alongside families through estate complexity, business transitions, and inheritance conversations. You have coordinated tax strategy, cash flows, and generational goals at the same time; because for most families, those things can't be separated. Our Team brings that depth to every engagement. Not because we're proud of our tenure, but because the people we serve deserve to work with real people whose judgment has been informed by real world complexity and a wide range of client circumstances. The values that haven't changed in 234 years The Buttonwood Agreement was forged in a crisis to restore confidence. That context mirrors what many clients feel when they first reach out to a firm like Buttonwood. The financial world is complex, opaque, and hard to navigate. Our commitment is to bring transparency, fiduciary responsibility, and honest communication to every relationship, the same values those brokers enshrined in 1792. Roots matter. They tell you where a firm stands when things get hard. On Buttonwood Agreement Day, we honor that founding moment, and recommit to carrying it forward. Connect with Buttonwood Financial Group If you're evaluating whether your current wealth management relationship reflects these values, we'd welcome the conversation. Our advisors work with individuals, families, and business owners on comprehensive, fiduciary-driven financial plans built around your long-term goals.
