Section 52.1 — Canada Pension Plan: Earnings for which first additional contribution deemed for month

For the purpose of calculating the first additional pensionable earnings of a contributor for a month in any year for which they have made a first additional contribution, that contribution is deemed to have been made for all months in the year, and the earnings for which the contributor is deemed to have made that contribution for each month in the year are an amount calculated by dividing their first additional unadjusted pensionable earnings for the year by 12, except that for a year in which the contributor reaches 18 years of age, the first additional contribution is deemed to have been made for earnings for the months in the year after they reached that age; and for a year in which the contributor reaches 70 years of age or dies or in which a retirement pension becomes payable to them under this Act or under a provincial pension plan, the first additional contribution is deemed to have been made for earnings for the months in the year before they reached 70 years of age or died or before the retirement pension became payable, as the case may be. If paragraph (a) or (b) applies, the earnings for which the contributor is deemed to have made a first additional contribution for each such month are an amount calculated by dividing their first additional unadjusted pensionable earnings for that year by the number of those months. For the purpose of calculating the first additional pensionable earnings of a contributor for a month in any year for which the contributor made no first additional contribution, the amount of the earnings for which that contribution is deemed to have been made for any month in the year is deemed to be zero. For the purposes of this Part, a contributor is deemed to have made a first additional contribution for any year for which their first additional unadjusted pensionable earnings exceed their basic exemption for the year, and is deemed to have made no first additional contribution for any year for which their first additional unadjusted pensionable earnings do not exceed their basic exemption for the year; and a contributor is deemed to have made a first additional contribution for earnings for any month for which a first additional contribution is deemed by subsection (1) to have been made by them.
