Under existing rules, the CCA for the year the property is acquired is subject to the so‑called “half-year” rule. Basically, for the year of acquisition, a taxpayer can claim CCA on only half of the amount added to the Class for that property. The other half remains in the UCC pool for the Class, so it can be deducted in future years, based on the percentage rate for the Class.
The new CCA measures replace the detrimental half-year rule with beneficial rules, as discussed below.
New rules for “accelerated investment incentive property”
The half-year rule is effectively eliminated for most depreciable capital properties, which are referred to as “accelerated investment incentive property” (“AII property”).
AII property acquired after November 20, 2018 and before 2024 will qualify for an accelerated CCA deduction in the year of acquisition (technically, in the year in which the property becomes “available for use”). In that year, an additional 50% of the cost of acquired property is added to the Class, which means that CCA can be deducted on 150% of the cost of the property in that year. After the year of acquisition, the CCA applies as usual to the balance in the Class.
