Plain English
In Canada, each person files their own taxes — there's no joint filing. So both of you should put money into your own RRSPs to get the biggest tax refund possible at your individual rates. Once both RRSPs are maxed, fill up both TFSAs equally. The key is to keep your investments roughly balanced between you. If one person has way more invested than the other, the government's attribution rules can reassign the income back to the higher earner for tax purposes. Keeping things balanced avoids that headache.
Spouse A earns $110,000, Spouse B earns $95,000. Spouse A contributes $19,800 to their RRSP (at 33.89% rate = $6,710 refund). Spouse B contributes $17,100 to theirs (at 31.48% rate = $5,383 refund). Combined refund: $12,093. Then each puts $7,000 into their TFSA for $14,000 total tax-free growth.
Show the analysis
Canada's individual-based taxation means each spouse independently traverses the progressive bracket structure. Maximizing both RRSPs captures the deduction at each spouse's respective marginal rate. For a $110K/$95K dual-income household in Ontario, combined marginal rates are approximately 33.89% and 31.48% respectively. Post-RRSP, equalizing TFSAs ensures balanced capital accumulation and avoids ITA s.74.1 attribution on inter-spousal transfers. During retirement, balanced RRIF withdrawals keep both spouses in lower brackets rather than concentrating income in one.
Spouse A: $110,000 income, $19,800 RRSP (18% of income). Refund: $19,800 × 33.89% = $6,710. Post-deduction income: $90,200. Spouse B: $95,000 income, $17,100 RRSP. Refund: $17,100 × 31.48% = $5,383. Post-deduction income: $77,900. Combined tax savings: $12,093/year. Both max TFSAs: $14,000 sheltered tax-free.
Edge cases
- If one spouse transfers investment capital to the other without a prescribed-rate loan, attribution rules (ITA s.74.1) attribute income/gains back to the transferor.
- If income disparity is large (e.g., $200K vs $50K), consider a spousal RRSP so the higher earner claims the deduction but withdrawals are taxed in the lower earner's hands.
