Small business lenders play a pivotal role in helping clients leverage tax incentives like Section 179 and bonus depreciation to optimize equipment financing. Understanding these deductions in 2025 is critical for lenders advising clients on capital expenditure decisions. This article examines current provisions, pending legislation, and strategic implications for your lending practice.
Current Legislation in 2025
Section 179 Deduction
- Deduction Limit: Businesses can deduct up to $1,250,000 for qualifying equipment and software placed in service by December 31, 2025.
- Phase-Out Threshold: The deduction begins to phase out dollar-for-dollar when total equipment purchases exceed $3,130,000, eliminating completely at $4,380,000.
- Eligible Property: Includes new and used equipment, off-the-shelf software, and certain vehicles (heavy SUVs with GVWR between 6,000-14,000 pounds, capped at $31,300).
- Income Limitation: Cannot exceed taxable business income, though unused amounts can be carried forward.
Bonus Depreciation
- Current Rate: 40% for assets placed in service in 2025 (following the phase-down from 100% through 2022, 80% in 2023, and 60% in 2024).
- Eligible Property: Covers new and used equipment, qualified improvement property (QIP), and certain plants with a useful life of 20 years or less.
- Key Advantages: No spending cap or income limitation, unlike Section 179.
- Application: Mandatory for all assets within the same class unless the business elects out.
- Phase-Down Schedule: Set to decrease to 20% in 2026 and 0% in 2027 without new legislation.
These provisions, established by the Tax Cuts and Jobs Act (TCJA) of 2017, continue to incentivize capital investments despite the declining bonus depreciation rate. Lenders should note that some states decouple from federal bonus depreciation rules or impose different Section 179 limits, potentially affecting clients’ net tax savings.
Pending Legislation and Proposed Changes
The landscape for these tax incentives could shift significantly in 2025, driven by proposals from the incoming administration and bipartisan efforts:
Reinstatement of 100% Bonus Depreciation
- Proposal: Draft legislation suggests reinstating 100% bonus depreciation retroactively from January 20, 2025, through December 31, 2029.
- Context: The House passed the Tax Relief for American Families and Workers Act in January 2024 (proposing 100% bonus depreciation for 2023-2025), but it stalled in the Senate. Republican priorities to make TCJA provisions permanent have created renewed momentum.
- Impact: If enacted, clients could deduct the full cost of qualifying assets in the first year, potentially driving significant demand for equipment financing.
Expansion of Section 179 Limits
- Proposal: Draft tax legislation proposes increasing the Section 179 deduction limit to $2.5 million and the phase-out threshold to $4 million (before inflation adjustments).
- Context: This aligns with earlier proposals like the Small Business Jobs Act, which aimed to broaden Section 179’s reach for small and mid-sized businesses.
- Impact: Higher limits would allow more clients to deduct larger equipment purchases upfront, reducing reliance on bonus depreciation and benefiting businesses with purchases above current thresholds.
Permanent TCJA Provisions
- Proposal: Discussions to make TCJA provisions permanent include maintaining expanded Section 179 limits and potentially extending bonus depreciation beyond 2026.
- Context: While the TCJA’s Section 179 enhancements are permanent (subject to inflation adjustments), bonus depreciation faces expiration without extension.
- Impact: Permanency would provide long-term certainty, enabling lenders to develop multi-year financing strategies with predictable tax benefits.
Likelihood and Timing of Changes
While proposals for 100% bonus depreciation and expanded Section 179 limits have bipartisan support, passage is not guaranteed. The Senate’s rejection of the 2024 tax bill highlights political hurdles, and the 2025 legislative calendar may delay action until mid-year.
However, the emphasis on tax cuts and economic stimulus, coupled with Republican control of Congress, increases the likelihood of at least partial enactment, possibly retroactive to January 2025.
Lenders should monitor developments through IRS updates (irs.gov) and industry resources like Section179.org, as retroactive changes could allow clients to amend 2025 returns for additional deductions.
Strategic Implications for Lenders
Advise Proactive Financing
- With bonus depreciation at 40% and potential for 100% reinstatement, encourage clients to accelerate 2025 purchases to secure deductions before lead times push assets past the December 31 deadline.
- Highlight leasing options (e.g., conditional sales leases) that preserve cash flow while maintaining eligibility for both deductions.
Prepare for Increased Demand
- If 100% bonus depreciation is restored, expect a surge in equipment and real estate financing, particularly from clients in construction, manufacturing, and agriculture.
- Develop specialized loan products to capitalize on this increased demand.
Address Potential Risks
- Warn clients about recapture risks if assets are sold soon after claiming deductions, as bonus depreciation and Section 179 deductions could be taxed at ordinary income rates (up to 37%).
- Note that large deductions may reduce qualified business income (QBI), potentially limiting the 20% QBI deduction available through 2025.
Stay Agile
- If legislation passes retroactively, help clients amend returns to claim enhanced deductions, strengthening your advisory relationship.
- Advise clients to consult tax professionals to navigate state decoupling issues and optimize federal-state tax strategies.
Conclusion
In 2025, Section 179 offers a robust $1.25 million deduction with a $3.13 million phase-out threshold, while bonus depreciation provides a 40% first-year write-off, set to decline further unless extended. Proposals to restore 100% bonus depreciation and expand Section 179 to $2.5 million could transform the equipment financing landscape.
Small business lenders should stay informed, promote timely purchases, and position themselves as strategic partners helping clients navigate these evolving tax incentives. By monitoring legislative updates closely and understanding their implications, you can provide valuable guidance that shapes your clients’ investment and financing decisions throughout 2025.
