Background
STC Steel Technologies Canada, Ltd., which reported its Canadian tax results in U.S. dollars, became the sole shareholder of Kasle Steel of Canada Ltd., which reported in Canadian dollars. Kasle Steel commenced and completed its wind-up on December 2, 2020. It held unused non-capital losses totaling C$2,693,199 from earlier taxation years.
The parties agreed that the losses became STC’s losses under subsection 88(1.1) of the Income Tax Act and had to be converted into U.S. dollars. Their sole dispute concerned when, and in whose hands, the conversion occurred. STC argued that the losses should first be deemed to belong to it and then be converted using rates associated with its taxation years, producing an asserted balance of US$2,651,791. The Minister converted the losses in Kasle Steel’s hands using the December 31, 2019 spot rate and reassessed the available deduction at US$2,073,494.
The Court’s Holding
The Tax Court dismissed STC’s appeal and upheld the reassessment. Justice Jenna Clark held that subsection 261(16) applied even though Kasle Steel’s wind-up began and ended on the same day. The subsidiary’s final taxation year included the wind-up’s commencement time and ended afterward because commencement necessarily preceded completion, even within that single day.
Subsection 261(16) therefore deemed subsection 261(5) to apply to Kasle Steel’s final year and deemed the parent’s U.S.-dollar reporting currency to be Kasle Steel’s elected functional currency. That made the final year a functional currency year and triggered subsection 261(7), which required Kasle Steel’s unused loss pool to be converted at the spot rate on the last day of its last Canadian-currency year—December 31, 2019.
The court held that this result did not conflict with subsection 88(1.1). Although the prior-year losses were not themselves part of Kasle Steel’s nil Canadian tax results for its final year, subsection 261(16) still brought the subsidiary into the functional-currency regime. The losses were converted to US$2,073,494 in Kasle Steel’s hands and then passed to STC on the wind-up.
Key Takeaways
- A subsidiary’s final taxation year can end after the commencement time of a wind-up even when commencement and completion occur on the same calendar day.
- When a Canadian-dollar subsidiary winds up into a functional-currency parent, subsection 261(16) can require the subsidiary to convert its unused non-capital losses before they transfer to the parent.
- The functional-currency rules may apply even when the subsidiary’s Canadian tax results for its final year are nil and no losses are deducted in that year.
Why It Matters
The decision clarifies how the Income Tax Act coordinates the corporate wind-up and functional-currency regimes. Tax attributes do not necessarily transfer to a parent in Canadian dollars for later conversion; where subsection 261(16) applies, they cross into the functional-currency regime in the subsidiary’s final taxation year.
The conversion date can materially change the value of inherited loss pools. Corporate groups planning vertical wind-ups should therefore account for the subsidiary’s last Canadian-currency year and the exchange rate prescribed by subsection 261(7).
