Terminal Loss

Definition

A terminal loss is the deduction allowed under Income Tax Act s.20(16) when a taxpayer disposes of the last remaining asset in a CCA class and the class still has positive undepreciated capital cost (UCC) at the end of the year. The policy recognises that cumulative CCA was too conservative: the taxpayer paid tax on income that should have been sheltered by a larger deduction, so the shortfall is written off all at once in the year the class empties.

Key rules

• Requirements for a terminal loss on a class:
  1. There are no remaining assets in the class at year end.
  2. The class has positive UCC after accounting for all additions and dispositions for the year.
  3. Dispositions in the year triggered by the last asset(s) must be bona fide arm's-length transactions or otherwise not subject to the stop-loss rule in s.13(21.1).
• Full deduction: the entire remaining UCC is deducted as ordinary business expense in the year, reducing net income on Schedule 1 of the T2.
• Special cases:
  • Class 10.1 passenger vehicles (single-asset class): terminal loss is not available on disposition. Half-year CCA in the year of disposition replaces it (Regulation 1100(2.5)).
  • Class 14.1 intangibles (post-2017): terminal loss mechanics apply, with special transitional rules for pre-2017 eligible capital property.
  • Non-arm's-length transfers: the stop-loss rule in s.13(21.1) may convert what looks like a terminal loss into a deferred cost basis for the acquirer, preventing recognition.
  • Change of use (business to personal) is a deemed disposition at fair market value; if the class empties, terminal loss mechanics apply.
• Rental property exception: s.1100(11) limits CCA on rental properties to the extent it creates a loss. However, the terminal loss on a disposition is still deductible; s.1100(11) applies to ongoing CCA claims, not to the winding-up of a class.

Example

A BC corporation's Class 8 UCC is $9,000 on January 1, 2026. It had two remaining desks. During 2026 it scraps both desks for total proceeds of $500. No other Class 8 assets are left at year end, and none are acquired later in the year.

1. Reduction to UCC = lesser of $500 (proceeds) and original cost of the desks (well above $500) = $500.
2. End-of-year UCC = $9,000 − $500 = $8,500.
3. No Class 8 assets remain at year end. The class is empty with a positive UCC.
4. Terminal loss under s.20(16) = $8,500, deducted on Schedule 8 and carried to Schedule 1.
5. UCC reset to zero going into 2027.

If the corporation re-acquired Class 8 property (for example, new desks) later in 2026, there would be no terminal loss because the class is no longer empty at year end. The positive UCC from the old desks and the additions from the new desks would pool normally, subject to the half-year rule.

Common mistakes

• Claiming a terminal loss while assets remain. The class must be fully emptied at year end.
• Re-buying similar property soon after a disposal and claiming terminal loss. The class is not empty at year end.
• Ignoring the stop-loss rule in s.13(21.1) when property is sold to a related party. The terminal loss may be denied and the acquirer picks up a deferred tax basis.
• Applying terminal loss to Class 10.1 passenger vehicles. The rule is specifically excluded; half-year CCA in the year of disposition is allowed instead.
• Forgetting that a change of use (for example, a vehicle moved from business to personal) is a deemed disposition at fair market value that can empty a class and trigger a terminal loss (or recapture).

Related concepts

Terminal loss is the mirror image of recapture. Both relate to the close-out of assets within the CCA framework. Earlier-year interactions include the half-year rule, and class-specific rules apply in Class 8, Class 10, and Class 50.
