69 F.3d 982 (9th Cir. 1995)
Sacks v. Commissioner is a leading Ninth Circuit decision at the intersection of the economic substance doctrine and congressionally targeted tax incentives.
Do investments in solar energy equipment lack economic substance—and thus fail to support investment tax credits and depreciation—merely because they would not be profitable without congressionally provided tax credits, and can the taxpayers' basis include nonrecourse debt that substantially exceeds the property's fair market value?
Under the economic substance doctrine, a transaction must have objective economic effects and/or a bona fide non-tax business purpose to be respected for tax purposes; however, when Congress has specifically provided a tax subsidy to induce particular investments, courts must evaluate substance in light of the intended subsidy rather than ignoring it. Nonrecourse debt that substantially exceeds the fair market value of the collateral, and is unlikely to be paid, is not included in basis for depreciation or credits (Estate of Franklin principle).
The Ninth Circuit held that the transactions could not be disregarded as shams solely because they would not have been profitable without the energy tax credits that Congress enacted to encourage such investments. However, the court agreed that taxpayers may not include inflated nonrecourse debt in basis where it exceeds the equipment's fair market value. The court reversed in part and remanded for recomputation of allowable credits and depreciation limited to the property's genuine basis.
Sacks is a cornerstone for understanding how the economic substance doctrine interacts with targeted tax incentives. It rejects a rigid pre-tax profit test where Congress has intentionally provided credits to tip the scales toward investment. Yet it preserves classic safeguards against abuse by limiting basis to fair market value and disregarding nonrecourse debt unlikely to be paid. For students, Sacks illustrates the balance between respecting legislative subsidies and preventing inflated, paper-driven tax benefits, a balance later echoed in the codified economic substance doctrine and related judicial analyses.
