## Senate Unveils Latest Draft of One Big Beautiful Bill: Key Tax Provisions Sharpen into Focus

- June 18, 2025

[ABGi USA](https://blog.abgi-usa.com/articles/author/abgi-usa)

**June 17, 2025**

 

With Monday’s release of the Senate Finance Committee’s amended text, the One Big Beautiful Bill Act takes a critical step forward in the tax reform process. As stakeholders continue tracking its evolution, the latest draft reinforces several familiar themes while refining key provisions impacting corporate and nonprofit taxpayers alike. 

 

#### Section 174: R&D Expensing Clarity and Retroactivity 

The Senate version confirms what many hoped for: a full suspension of R&D amortization. Notably, the provision also includes retroactive application—a significant detail for companies that have already begun planning under the amortization rules. This would allow for immediate expensing of R&D costs, easing financial burdens and encouraging near-term innovation investments. 

 

#### Bonus Depreciation: Holding at 100% 

Echoing business priorities, the draft bill restores 100% bonus depreciation—a reversal of the phase-down path currently in place. If passed, this would enable companies to continue front-loading deductions on qualifying assets through at least 2027. 

 

#### Business Interest: EBITDA Returns, For Now 

The bill proposes a temporary return to an EBITDA-based interest deduction limit under Section 163(j), shifting back from the more restrictive EBIT-based framework. This change may provide short-term relief to capital-intensive sectors while a more permanent approach is developed. 

 

#### Nonprofits: Tax Complexity Grows 

The nonprofit sector faces renewed complexity.

- **Excise tax on investment income** could rise substantially for institutions with $2M+ in endowment per student, although the top rate has dropped from 21% in the House version to **8% in the Senate draft. **
- **Royalty income rules** are also under review, potentially expanding the definition of unrelated business taxable income for organizations leveraging brand and logo assets. 
- The **transportation fringe benefit tax** returns—reviving a compliance burden familiar from 2017–2018. 

 

#### Political Temperature: Divided but Driven 

Senator Mike Crapo calls this a bill that prevents “an over-$4 trillion tax hike,” aligning it with efforts to solidify Trump-era tax cuts. Meanwhile, Democratic leadership frames the bill as deepening inequality and threatening essential public funding. 

**And yet, July 4th remains a target date**—still floated by some, but doubted by others—as the legislative window narrows. With procedural hurdles ahead and sharp partisan contrasts, **ABGi will continue to monitor what’s happening and keep you informed**.
