My corporation previously had a fiscal year from March to February. CRA has approved a change to a calendar year-end, so we will have a short taxation year from March 1, 2025 to December 31, 2025, and thereafter future years will be January–December.
However, my corporation also became a non-CCPC effective July 1, 2025.
I am trying to understand how the small business deduction (SBD) limit is prorated in this situation.
Specifically:
Is the SBD limit for the short year (Mar 1 – Dec 31, 2025) prorated based on the full short taxation year length (March to December)?
Or is it effectively only prorated for the period the corporation was a CCPC (i.e., March 1 – June 30, 2025, when it was still CCPC), since after July 1 it became a non-CCPC?
In other words, does the SBD apply only up to the date CCPC status ends, or for the entire short taxation year?
Thank you for your guidance
Hi,
Thank you for your question.
Based on the facts provided, the Small Business Deduction should apply only for the period during which the corporation was a CCPC.
Since the corporation became a non-CCPC effective July 1, 2025, the corporation is generally deemed to have a taxation year-end immediately before that change, being June 30, 2025. This means the relevant CCPC taxation year would be March 1, 2025 to June 30, 2025.
The SBD business limit should therefore be prorated based on the number of days in that CCPC taxation year, not the full March 1 to December 31, 2025 period.
For example:
$500,000 × 122 days / 365 = approximately $167,123
Accordingly, the corporation would generally be eligible to claim the SBD only on qualifying active business income earned during the CCPC taxation year from March 1, 2025 to June 30, 2025, subject to the usual SBD limitations, including associated corporation rules, taxable capital grind, passive investment income grind, and other restrictions.
The corporation would generally not be eligible for the SBD for the period from July 1, 2025 to December 31, 2025, because it was no longer a CCPC during that period.
In short, the SBD does not apply for the entire March 1 to December 31 short year. It should be limited to the deemed short taxation year ending immediately before the corporation ceased to be a CCPC.
We recommend reviewing the ownership/control change documents and the timing of the income earned to ensure the T2 return is prepared correctly.
