Section 10 — Canada Pension Plan: Base contribution in respect of self-employed earnings

Every individual who is resident in Canada for the purposes of the Income Tax Act during a year and who has contributory self-employed earnings for the year shall make a base contribution for the year of an amount equal to the product obtained when the contribution rate for self-employed persons for the year is multiplied by the lesser of the individual’s contributory self-employed earnings for the year, minus the amount by which the individual’s basic exemption for the year exceeds the aggregate of all amounts deducted as prescribed on account of the individual’s basic exemption for the year whether by one or more employers pursuant to section 8, and all amounts deducted as prescribed by or under a provincial pension plan on account of any like exemption for the year whether by one or more employers pursuant to that plan, and the individual’s maximum contributory earnings for the year, minus the individual’s salary and wages, if any, on which a base contribution has been made for the year and the amount, if any, that is determined in the prescribed manner to be the individual’s salary and wages on which a base contribution has been made for the year by the individual under a provincial pension plan. For 2019 and each subsequent year, an individual referred to in subsection (1) shall also make a first additional contribution for the year of an amount equal to the product obtained when the first additional contribution rate for self-employed persons for the year is multiplied by the lesser of the individual’s contributory self-employed earnings for the year, minus the amount by which the individual’s basic exemption for the year exceeds the aggregate of all amounts deducted as prescribed on account of the individual’s basic exemption for the year whether by one or more employers under section 8, and all amounts deducted as prescribed by or under a provincial pension plan on account of any like exemption for the year whether by one or more employers under that plan, and the individual’s maximum contributory earnings for the year, minus the individual’s salary and wages, if any, on which a first additional contribution has been made for the year and the amount, if any, that is determined in the prescribed manner to be the individual’s salary and wages on which a first additional contribution has been made for the year by the individual under a provincial pension plan. For 2024 and each subsequent year, an individual referred to in subsection (1) shall also make a second additional contribution for the year of an amount equal to the product obtained when the second additional contribution rate for self-employed persons for the year is multiplied by the amount by which the individual’s contributory self-employed earnings for the year — not exceeding the individual’s additional maximum pensionable earnings for the year — exceeds the individual’s maximum pensionable earnings for the year, minus the individual’s salary and wages, if any, on which a second additional contribution has been made for the year and the amount, if any, that is determined in the prescribed manner to be the individual’s salary and wages on which a second additional contribution has been made for the year by the individual under a provincial pension plan. For the application of subsections (1), (1.1) and (1.2), if a person, in a year, is an employee of a corporation that is controlled by the person, ceases to be employed by that corporation and becomes self-employed, the person may take into account the amount of contributory salary and wages paid by the corporation to the employee in the year as contributory self-employed earnings of the person in the year; and take into account the amounts deducted, remitted or contributed by the corporation in relation to the employee’s contributions and the employer’s contributions in respect of the person for the year as contributions by the person in respect of self-employment earnings in that year.
