A Canada Pension Plan (CPP) credit split allows eligible couples to divide their CPP retirement pension credits. This can be beneficial for couples where one spouse has significantly higher earnings than the other. By splitting their credits, the couple can increase the CPP retirement benefits for the lower-earning spouse.
To be eligible for a CPP credit split, the couple must have been married or in a common-law relationship for at least one year, and one of the spouses must have been the primary caregiver for a child under the age of 7 for at least one year. The credit split can be applied retroactively for up to 11 years.
