When both spouses or common-law partners are eligible for Canada Pension Plan retirement benefits, they may be able to share a portion of their CPP retirement pensions. CPP pension sharing allows part of the pension entitlement earned during the period of the relationship to be allocated between spouses. This can be useful for tax planning because it may shift some income from the higher-income spouse to the lower-income spouse, potentially reducing the household’s overall tax burden. It does not mean each spouse automatically receives the higher or lower benefit. It also does not mean each spouse is restricted only to their own amount in every case. Therefore, the correct treatment is that spouses can share a portion of the total pension amount.
