Ashland Inc. v. Commissioner of Revenue, 899 N.W.2d 812

Ashland Inc., a domestic unitary business, acquired Hercules (a C corporation) which wholly owned Hercules SARL, a Luxembourg SARL that in 1999 elected to be disregarded for federal tax purposes by filing Form 8832.
For federal returns, Hercules treated Hercules SARL as a disregarded entity (a branch/division), so SARL’s income, losses, and deductions were reported as Hercules’s for the years ending 2009–2011.
Minnesota defines “net income” by incorporating federal taxable income and “any elections” made for federal tax purposes (Minn. Stat. § 290.01, subd. 19), which Ashland used in its combined Minnesota unitary return.
Minnesota’s water’s edge rule (Minn. Stat. § 290.17, subd. 4(f)) excludes the net income and apportionment factors of foreign entities from combined reports; the Commissioner excluded Hercules SARL’s items and assessed additional tax.
The tax court granted summary judgment to Ashland, holding Minnesota must recognize the federal election and its consequences (deemed liquidation/distribution), so SARL’s income was reported as Hercules’s and not a foreign member’s income.
The Commissioner appealed, arguing the water’s edge statute prohibits treating the foreign SARL’s income as part of the combined report despite the federal election.

Issue	Commissioner’s Argument	Ashland’s Argument	Held
Whether Minnesota must recognize the federal “check‑the‑box” election and its consequences when computing Minnesota net income	Federal election’s consequences should not override the water’s edge exclusion; SARL remains a foreign entity whose income must be excluded	Minnesota’s net income statute incorporates “any elections,” so the federal disregarded‑entity treatment (deemed liquidation/distribution) applies and SARL’s items become Hercules’s	Court affirmed tax court: Minnesota must incorporate the federal election and its consequences; SARL’s income is reported as Hercules’s
Whether SARL’s foreign nationality independently prevents inclusion despite federal disregarded status	Nationality is distinct from classification; SARL remains foreign so exclusion applies	Once disregarded, SARL’s income/losses are treated as part of domestic Hercules’s business activity, making nationality irrelevant for combined reporting	Held that SARL’s foreign nationality does not bar inclusion because the federal election deemed SARL’s assets/liabilities part of domestic Hercules
