For couples

Retirement planning for couples

Canada taxes each spouse separately, but the rules give couples room to move: pension income splitting, CPP sharing, spousal RRSPs, and an OAS clawback that is tested per person. Then there is the question most calculators skip: what happens to the household's income when one of you dies. The tools and guides below answer those questions with the government's own figures, each with its source and verified date.

Good to know

Which couple questions does this site answer with the government's own numbers?
Whether to split pension income and by how much, whether CPP sharing helps, where each spouse sits against the OAS clawback line, what the GIS pays a couple, when each of you should start CPP and OAS, what happens to CPP, OAS and registered accounts when one spouse dies, and whether the household's money lasts. Every page names its source and the date it was verified.
What is the difference between pension income splitting and CPP sharing?
Pension income splitting is a CRA election on the tax return (form T1032) that moves up to 50% of eligible private pension income on paper; CPP and OAS are never eligible. CPP sharing is a Service Canada application that changes who is actually paid part of the CPP earned while you lived together. You can use both; the couples planner applies both every year.
Is the OAS clawback based on our combined income?
No. The recovery tax is assessed on each spouse's own net income, 15% of the amount over $93,454 of 2025 income for payments from July 2026 to June 2027. The GIS, by contrast, is tested on a couple's combined income.
Does RetireSmarter cover Quebec couples?
The tax engine includes Quebec's brackets and the federal abatement, and every CPP page notes that Quebec residents are under the QPP, which has similar but not identical rules, administered by Retraite Québec.
