At $750K+ AGI you live at the 37% federal bracket. In California you cross 50.3% combined. The brackets do not bend — and bonus and AMT add friction on top.
A four-month exit. An RSU vest. A bonus year. A K-1 windfall. Income arrives, and the calendar gives you weeks — not quarters — to deploy mitigation before tax-year close.
Syndicated conservation easements are listed transactions. Oil-and-gas drilling is volatile. §1031 needs replacement property in 45 days. Code-clean, defensible alternatives are rare and getting rarer.
Energy storage — including standalone batteries — now qualifies for the Clean Electricity Investment Tax Credit. 6% base; 30% with PWA; +10% domestic content; +10% energy community.
The One Big Beautiful Bill Act restored §168(k) to 100% first-year bonus depreciation for qualified property acquired and placed in service after January 19, 2025.
§6418 transferability rules are in production. Buyers without sufficient current-year liability can transfer credits to unrelated parties for cash, typically at 92–95¢ on the dollar.
§50(c)(3) basis reduction: depreciable basis = $1M − (50% × $300K ITC) = $850K. Then §168(k) 100% bonus = $850K Year-1 deduction. At 37% federal + 5% state blended = $357K tax savings on the deduction. Combined with the $300K credit = $657K Year-0 benefit per $1M deployed.

| Code Section | Name | What It Does |
|---|---|---|
| IRC §48E | Clean Electricity Investment Tax Credit | Tech-neutral ITC for qualifying energy property — including standalone storage — placed in service after 12/31/2024. Base 6%; up to 30% with PWA; +10% domestic content, +10% energy community. |
| IRC §168(k) | Bonus Depreciation | Restored to 100% by OBBBA (signed 7/4/2025) for qualified property acquired and placed in service after 1/19/2025. |
| IRC §50(c)(3) | Depreciable Basis Reduction | Depreciable basis of property qualifying for an energy credit must be reduced by 50% of the credit claimed. |
| IRC §39 | General Business Credit Carry | 1-year carryback, 20-year carryforward of unused general business credits — including the §48E ITC. |
| IRC §6418 | Tax-Credit Transferability | Permits one-time sale of qualifying energy credits to unrelated parties for cash. Secondary-market pricing typically 92–95¢/$1. |
| # | Risk | Mitigation |
|---|---|---|
| 1 | IRS audit risk on §48E claim | Cost-segregation study and independent tax opinion delivered at acquisition. Documentation packet retained. |
| 2 | §50(a) recapture if asset disposed in <5 years | Five-year hold built into the structure. Recapture schedule disclosed in subscription documents. |
| 3 | Illiquidity | Asset is non-traded private property. Optional secondary path: §6418 credit transfer (~92–95¢/$1) or operating-revenue sale of the asset. |
| 4 | Valuation risk | USPAP-compliant appraisal by named MAI or ASA appraiser. Comparable-transaction support delivered with PPM. |
| 5 | Regulatory change | OBBBA (2025) and §48E (2025) are both current law. Adverse change requires Congressional action and would not retroactively void credits already claimed. |
| 6 | §469 passive-activity cap | Pre-qualifying screen confirms buyer has passive income or material participation. Unusable credit suspends — does not expire — under §469. |
