The Initial Tax Problem
Despite strong operating performance, the client faced a large federal tax bill annually. Capital improvements were expensed conservatively, and credits were not modeled alongside income timing.
Key Issues Discovered
- No investment tax credits utilized
- Capital improvements depreciated slowly
- No coordination between credits and taxable income
- Excess taxable income despite reinvestment
- No sequencing of deductions, depreciation, and credits
Discovery and Diagnostic Phase
We evaluated upcoming capital expenditures and identified a solar installation that qualified for the federal investment tax credit. We then modeled depreciation, credit timing, and income absorption to determine whether a zero-tax outcome was achievable without creating unusable carryforwards.
This Included:
- Solar project eligible for 30% ITC
- Significant bonus depreciation available on remaining basis
- Sufficient taxable income to absorb credits fully
- Ability to coordinate deductions and credits in the same year
Key Implementation Strategies
1
$243,000 Estimated Tax Benefit
Solar Investment Tax Credit (ITC)
Actions Taken
• Installed a qualifying commercial solar system
• Total project cost: $810,000
• Qualified for 30% federal ITC
ITC Calculation
$810,000 × 30% = $243,000 credit
This credit directly offset federal income tax dollar-for-dollar.

Depreciable Basis Adjustment and Bonus Depreciation
Actions Taken
• Reduced depreciable basis by 50% of ITC as required
• Applied bonus depreciation to remaining eligible basis
Depreciation Math
Original Basis: $810,000
ITC Basis Reduction (50% of $243,000): $121,500
Adjusted Basis: $688,500
Bonus-eligible portion depreciated in year one generated a large non-cash deduction.
At an effective marginal rate of approximately 47.3%:
$344,000 × 47.3% ≈ $162,800
