Safe Income Allocation in Spin-Out Transactions: CRA Confirms a Value-Driven Approach

Overview

In recent administrative guidance, the Canada Revenue Agency (CRA) has clarified its approach to the allocation of safe income for purposes of subsection 55(2) of the Income Tax Act. Drawing on its 2023 Canadian Tax Foundation (CTF) paper and subsequent comments at the 2025 STEP Conference, the CRA has confirmed a central organizing principle: safe income follows economic value, not share arithmetic.

This guidance is particularly relevant in the context of spin-out and divisive reorganizations, where the location of safe income can materially affect the application of subsection 55(2) both within a related group and on subsequent arm’s-length dispositions.


Legal Context

The courts have long held that safe income must be allocated pro rata among shares and may not be selectively assigned to avoid subsection 55(2). The Federal Court of Appeal’s decision in The Queen v. Placer Dome and the reasoning in Nassau Walnut establish that the proper inquiry is whether income contributes to the gain inherent in particular shares.

Critically, neither case requires strict tracing of income to specific assets. Rather, the jurisprudence supports a principled allocation that reflects economic reality.


CRA’s Illustrative Example

In its 2023 CTF paper, the CRA considered a divisive transaction in which:

  •  A wholly-owned subsidiary (Opco) earns $1,000 of after-tax income, constituting

  • direct safe income.

  •  That income is fully reinvested in a particular asset.

  •  The asset is transferred to a newly incorporated subsidiary (Newco) as part of a spin-out transaction.

  •  Following the reorganization, Opco retains assets with no embedded safe income, while Newco owns the asset that embodies all the income.

Although only a portion of Opco’s shares are transferred to effect the reorganization, the CRA concluded that all of the safe income shifts to the Newco shares.


Analytical Framework: Contribution to Gain

The CRA’s conclusion reflects a disciplined application of the contribution-to-gain test. Once the asset that embodies the safe income leaves Opco, the retained Opco shares no longer reflect that income in their accrued gains. Conversely, the value of the Newco shares is directly supported by the transferred asset and the income it represents.

This approach avoids conflating formal share mechanics with economic substance. While the allocation must be pro rata, the relevant metric is the cost amount of assets transferred or retained, not the percentage of shares exchanged.


Allocation Methodology

To implement this analysis without resorting to impractical tracing, the CRA endorsed a cost-amount-based allocation formula that allocates safe income by reference to:

  • the net cost amount of assets transferred to Newco, and

  • the total cost amount of Opco’s assets immediately before the reorganization.

Where all of the cost amount attributable to safe income is transferred, the formula necessarily results in a complete migration of safe income, even if only part of the share capital is involved in the reorganization.


Application Beyond Butterfly Transactions

At the 2025 STEP Conference, the CRA confirmed that this analysis is not contingent on the availability of paragraph 55(3)(a) butterfly exemption. Nor does it depend on the shares remaining within a related group.

Where safe income is reflected in assets transferred to a new corporation, that safe income shifts with those assets, even if the transaction forms part of a series that includes a sale to an unrelated third party.


Implications for Subsection 55(2)

The practical effect of this approach is that dividends arising on the redemption of spun-out shares may be fully sheltered by safe income, preventing the application of subsection 55(2), even where those shares represent only a portion of the overall corporate value.

While this result may appear counterintuitive at first glance, it is consistent with the underlying policy of subsection 55(2), which targets only the portion of a dividend that exceeds the income reasonably contributing to the gain on the relevant shares.


Our Commentary

The CRA’s guidance represents a coherent and economically grounded approach to safe income allocation. By focusing on where income is actually reflected after a transaction, the CRA has provided a framework that aligns with both jurisprudence and modern transactional practice.

For planners, however, the guidance underscores the importance of understanding how safe income may shift as assets are reorganized. Once safe income migrates to spun-out shares, it may no longer be available to support dividends on retained shares in later transactions.

Careful modelling of safe income allocation should therefore be a central component of any divisive reorganization involving significant embedded income.
