Accelerated Investment Incentive Property (AIIP)

AIIP replaced the half-year rule with a 1.5× first-year CCA for most depreciable property, and is being phased out between 2024 and 2027.

Definition

Accelerated Investment Incentive Property (AIIP) is a temporary CCA regime introduced in the 2018 Fall Economic Statement. For qualifying property, the half-year rule is suspended and the first-year CCA is increased to 1.5× the normal declining-balance amount. The policy was designed to encourage business investment. AIIP is phasing out: full 1.5× treatment applied to property available for use before 2024, a reduced enhancement applies from 2024 to the end of 2026, and the program concludes at the end of 2027 (confirm final 2026 and 2027 regulations annually, as phase-out percentages are set in Regulations 1100(2.02)).

Key rules

  • To be AIIP, the property must (per Regulations 1104(4)):
    • Be acquired after November 20, 2018.
    • Be new to the taxpayer (or acquired from an arm's-length person who never used it, or never claimed CCA).
    • Become available for use before 2028.
    • Not be excluded property (property previously owned or used by the taxpayer or a non-arm's-length person, and property that was deductible under immediate expensing or the manufacturing and processing 100% rule, which are separate incentives).
  • Phase-out schedule as originally enacted (confirm current Regulation 1100(2.02) for each class before filing):
  • Specific manufacturing and processing (class 53) and clean-energy (classes 43.1, 43.2) assets received a separate 100% first-year deduction; that sub-regime also phases out on the same schedule.
  • Short tax years still pro-rate the enhanced CCA by days over 365.
  • Recapture and terminal loss rules continue to apply normally.

AIIP does not increase total lifetime CCA. It front-loads the deduction. Over the life of the asset, total CCA equals capital cost less salvage value recognised at disposition.

Example

A BC corporation buys a $20,000 server in March 2026 that qualifies as AIIP in class 50 (55% rate). It is the only class 50 asset.

  1. Under normal rules with the half-year rule: CCA = ($20,000 × 50%) × 55% = $5,500.
  2. Under 2026 AIIP (1.25× enhancement, no half-year rule): CCA = $20,000 × 55% × 1.25 = $13,750.
  3. Closing UCC = $20,000 − $13,750 = $6,250.
  4. In year 2, CCA = $6,250 × 55% = $3,437.50 (ordinary declining balance).

The front-loaded deduction reduces 2026 tax payable, accepting lower deductions in later years.

Common mistakes

  • Claiming AIIP on a used asset acquired from a related party. AIIP requires "new" to the taxpayer in the sense of s.1104(4), with limited exceptions.
  • Layering AIIP on top of the half-year rule. AIIP replaces the half-year rule for the first year; do not reduce the base by 50% and then multiply by 1.25.
  • Applying AIIP to property that also qualifies for immediate expensing. A CCPC can only claim one of the incentives; immediate expensing is usually more valuable if the $1.5M cap applies.
  • Using an outdated phase-out percentage. Check Regulation 1100(2.02) for each available-for-use year.
  • Including AIIP property that became available for use after December 31, 2027.

AIIP is a temporary override to the . It interacts with (CCPCs choose between them for overlapping property) and affects the CCA computation for every class, including and . See for the mechanics.
