Who this is for
People deciding where to put savings this year. That includes employees with room in both, and self-employed people with no pension. It also includes newcomers deciding which account to open first, and families wondering why the answer keeps changing.
The five questions that actually decide it
-
What is your tax rate now, and what will it be when you withdraw? The RRSP works best when the rate at withdrawal is lower than the rate at contribution. A high earner saving for retirement at a lower income usually fits. A student or someone on parental leave with low income this year usually does not. They may do better carrying RRSP room forward and using the TFSA now.
-
Will the withdrawal reduce a benefit? RRSP withdrawals are income. They can reduce the Canada child benefit, the GST-related credits, Old Age Security and the Guaranteed Income Supplement. TFSA withdrawals are not income and affect none of these.
-
Might you need the money back soon? TFSA room returns the January after a withdrawal. RRSP room is gone once used. Withdrawals have tax withheld at source: 10% up to $5,000, 20% up to $15,000, 30% above. The full tax is settled on the return. The RRSP suits money you will not touch; the TFSA suits money you might.
-
Do you have a pension at work? A pension adjustment reduces RRSP room. Someone with a good defined-benefit pension often has little RRSP room and more use for the TFSA.
-
How disciplined are you with a refund? The RRSP’s advantage assumes the refund is saved, not spent. If the refund goes to a holiday, the TFSA with the same cash often ends up ahead.
Two situations where the answer is clearer
A self-employed person with high income and no pension: the RRSP. The deduction is worth a lot now and provides the retirement income a pension would have. A low-income year with children at home: the TFSA. An RRSP deduction saves little tax, and the Canada child benefit is already at or near its maximum.
How the pieces connect
The RRSP interacts with benefits through net income, the TFSA does not. An RESP is for a child’s education and attracts grant; it is not a retirement account. Life insurance is not a savings account at all; it replaces income if you die. Each tool has a job, and the right mix depends on your income this year, not on which account is better in the abstract.
One thing many people do not realize
The RRSP deduction is not a tax saving. It is a tax deferral. The money comes back into income when you withdraw it, at whatever rate applies then. If your rate at withdrawal is lower than your rate now, you keep the difference. If it is higher, the deferral costs you. A TFSA has no deferral: the tax was paid before the money went in, and it is never taxed again.
What to prepare
- Your Notice of Assessment, with the RRSP deduction limit
- Your TFSA room
- Expected income this year and a rough idea of retirement income
- Whether you have a pension at work (the pension adjustment on your T4)
When professional help may make sense
Income that swings year to year, or a spouse with a much lower income. A planned maternity or parental leave. A year of unusually high income from a sale or bonus.
