The Return of EBITDA: Unlocking Higher Leverage Capacity
The One Big Beautiful Bill Act’s restoration of EBITDA-based business interest deduction calculations through 2029 represents a transformative change for leveraged transactions and debt-financed growth strategies. By expanding the 30% limitation base to include depreciation, amortization, and depletion, the legislation increases deductible interest capacity by 25-60% for most companies, fundamentally improving M&A economics and enabling more aggressive capital allocation strategies.
Technical Framework: Understanding Section 163(j) Enhancement
Calculation Methodology Transformation
Pre-OBBB Limitation (2022-2024):
- Deductible business interest limited to 30% of adjusted taxable income (EBIT-based)
- Excludes depreciation, amortization, and depletion from base calculation
- Creates significant limitations for capital-intensive and high-growth companies
OBBB Enhancement (2025-2029):
- Restores EBITDA-based calculation methodology
- Includes depreciation, amortization, and depletion in limitation base
- Maintains 30% limitation rate while dramatically expanding eligible income base
Technical Components:
- Base Income: Net income plus interest, taxes, depreciation, amortization
- Interest Income Add-back: Business interest income increases limitation
- Floor Plan Financing: Separate unlimited deduction for inventory financing
- Carryforward Provisions: Disallowed interest carries forward indefinitely
Quantitative Impact Analysis
For a typical leveraged company with $100 million EBITDA:
- EBIT (after $25 million D&A): $75 million
- Old limitation: $22.5 million deductible interest
- New limitation: $30 million deductible interest
- Improvement: $7.5 million additional deductible interest
- Annual tax savings: $1.58 million at 21% rate
M&A Transaction Optimization: The Leverage Advantage
Leveraged Buyout Enhancement
The EBITDA restoration dramatically improves LBO economics by enabling higher sustainable leverage ratios:
5x EBITDA Transaction Example:
- Target company: $50 million EBITDA, $12 million D&A
- Debt capacity: $250 million at 7.5% interest
- Annual interest expense: $18.75 million
Under EBIT Rules:
- Limitation base: $38 million EBIT
- Deductible interest: $11.4 million
- Disallowed interest: $7.35 million
- After-tax interest rate: 9.12%
Under EBITDA Rules:
- Limitation base: $50 million EBITDA
- Deductible interest: $15 million
- Disallowed interest: $3.75 million
- After-tax interest rate: 8.09%
- Annual tax savings: $756,000
Strategic Acquisition Financing
Debt Capacity Optimization: The enhanced deduction enables private equity firms and strategic acquirers to support higher leverage multiples:
- 3x EBITDA: Typically full interest deductibility
- 4x EBITDA: Generally manageable with modest limitations
- 5x EBITDA: Viable for high-margin, stable cash flow targets
- 6x+ EBITDA: Possible for exceptional situations with strong EBITDA growth
Transaction Structure Implications:
- Higher debt-to-equity ratios in acquisition financing
- Enhanced IRRs for equity investors
- Improved competitive positioning in auction processes
- Greater flexibility in covenant negotiations
Strategic Acquisition Case Study
$500 Million Manufacturing Acquisition:
- Target EBITDA: $75 million
- Depreciation & Amortization: $20 million
- Acquisition debt: $375 million (5x EBITDA) at 8% interest
- Annual interest: $30 million
Financial Impact Comparison:
- EBIT-based limitation: $16.5 million deductible
- EBITDA-based limitation: $22.5 million deductible
- Additional deductible interest: $6 million
- Annual tax savings: $1.26 million
- NPV benefit over 7-year hold: $6.8 million at 10% discount rate
Corporate Development Strategy Enhancement
Growth Capital Optimization
Mid-sized companies pursuing aggressive growth strategies benefit significantly from enhanced interest deductibility:
Expansion Financing Example:
- Growing technology company with $150 million revenue
- EBITDA: $30 million with $8 million D&A

- EBITDA-based limitation: $9 million fully deductible
- Tax savings: $504,000 annually
- Enhanced debt capacity: 36% improvement
Refinancing and Capital Structure Optimization
Debt Refinancing Opportunities: Companies can optimize capital structures by:
- Increasing total debt levels within enhanced deductibility limits
- Refinancing existing debt at higher principal amounts
- Extracting equity through special dividends
- Improving overall cost of capital
Strategic Recapitalization:
- Example: $200 million EBITDA company with $50 million D&A
- Enhanced deductible capacity: $60 million (vs. $45 million under EBIT)
- Additional debt capacity: $200-300 million depending on interest rates
- Potential equity extraction: $150-250 million for growth or shareholder returns
Industry-Specific Applications

Strategic Debt Management
Timing Optimization Strategies
2025-2029 Planning Window: Companies should evaluate:
- Accelerating debt-financed acquisitions into the EBITDA period
- Refinancing existing debt to capture enhanced deductibility
- Implementing dividend recapitalizations while benefits are available
- Planning capital allocation around temporary enhancement
Interest Rate Environment Coordination
Rising Rate Mitigation: Enhanced deductibility partially offsets rising interest rate impacts:
- Higher absolute deduction limits buffer rate increases
- Improved after-tax borrowing costs
- Enhanced debt service coverage ratios
- Better covenant compliance margins
Documentation and Compliance Strategy
Section 163(j) Election Management:

- Plan for carryforward utilization strategies
- Document business purpose for interest-heavy structures
Integration with Other OBBB Provisions
Multiplicative Benefits Strategy
The business interest enhancement combines powerfully with other OBBB provisions:
Manufacturing Investment Integration:
- QPP immediate depreciation increases EBITDA base
- Bonus depreciation on equipment enhances limitation calculation
- R&D expensing improves overall profitability and debt capacity
- Combined effect can improve project returns by 500+ basis points
Acquisition Structure Optimization:
- Asset purchases benefit from immediate depreciation on acquired assets
- Enhanced interest deductibility on acquisition debt
- R&D expensing for technology acquisitions
- Integrated approach maximizes combined tax benefits
State Tax Considerations
Conformity Analysis
Most states do not conform to federal Section 163(j) calculations, creating planning complexity:
Non-Conforming States:
- California: Maintains separate interest limitation rules
- New York: Uses federal EBIT-based calculation regardless of federal changes
- Illinois: Adds back federal interest deductions above state limitations
- Texas: No corporate income tax, avoiding conformity issues
Strategic Implications:
- Multi-state companies must model combined federal and state impacts
- Potentially significant temporary differences for financial reporting
- Cash flow benefits primarily at federal level
- State apportionment planning becomes more critical

Conclusion: Capitalizing on Enhanced Leverage Capacity
The restoration of EBITDA-based business interest calculations through 2029 creates substantial opportunities for leveraged growth and M&A strategies. For mid-sized and larger companies, the enhanced deductibility can improve debt capacity by 25-60%, fundamentally altering the economics of leveraged transactions and debt-financed growth initiatives.
The five-year window for enhanced benefits creates urgency around strategic planning, particularly for companies considering major acquisitions, growth capital raising, or capital structure optimization. Companies that act decisively to capture these benefits will achieve meaningful competitive advantages through improved cost of capital and enhanced financial flexibility.
The interaction of enhanced interest deductibility with other OBBB provisions—particularly bonus depreciation and QPP benefits—creates multiplicative advantages for companies pursuing integrated growth strategies. A comprehensive approach that optimizes all available tax benefits can improve transaction returns by 400-600 basis points while strengthening balance sheets and market positions.
Private equity firms and strategic acquirers should immediately reevaluate transaction criteria and leverage assumptions, as the enhanced deductibility enables higher sustainable debt levels and improved equity returns. The temporary nature of these benefits favors accelerated transaction timelines and aggressive capital allocation during the 2025-2029 window.
