RRSP vs TFSA at $80,000: The Ontario numbers

At $80,000 in Ontario, you're in a 31.5% marginal tax bracket. Put $5,000 into an RRSP and you get $1,575 back on your tax return. Put that same $5,000 into a TFSA and you get nothing back - but you never pay tax on what it grows into.

The math isn't close at this income level. The RRSP wins.

Here's why: that $1,575 refund is real money you can spend or invest. If you reinvest it, you're effectively contributing $6,575 total ($5,000 RRSP + $1,575 refund) versus $5,000 in the TFSA. Even accounting for the tax you'll pay when you withdraw from the RRSP later, you come out ahead.

The numbers at retirement

Say both accounts grow at 6% annually for 25 years. Your $5,000 TFSA becomes $21,461 - all yours, tax-free.

Your $5,000 RRSP becomes $21,461 too, but you owe tax when you withdraw. If you're retired and pulling $50,000 total income, your marginal rate in Ontario drops to about 25%. You keep $16,096 after tax.

But remember that $1,575 refund you reinvested? At 6% for 25 years, it becomes $6,734. Add them together: $16,096 + $6,734 = $22,830.

The RRSP strategy nets you $1,369 more than the TFSA - assuming you actually invest the refund instead of spending it.

The catch everyone misses

That calculation assumes your tax rate drops in retirement. At $80k now, you're at 31.5%. If you retire with the same spending power - maybe you have a pension, maybe you built a large RRSP - you might still be at 31.5% or higher when you withdraw.

In that case, the accounts are roughly equal. The RRSP's upfront tax break gets canceled out by the tax you pay later.

This is why some people at $80k choose the TFSA anyway. They're betting their retirement income will be higher than expected, or they want the flexibility to withdraw without triggering more tax.

Room to use both

At $80k, your 2025 RRSP limit is probably around $14,400 (18% of last year's earned income). Your TFSA room is $7,000 for 2025, plus whatever you haven't used from previous years.

You don't have to pick just one. A common approach: maximize the RRSP first for the tax refund, then put any leftover savings into the TFSA.

TaxSplit.ca shows the exact refund based on your specific income and province - the rates shift slightly each year and vary by how much you earned.

The RRSP makes more sense at $80k in Ontario, but only if you're disciplined about investing the refund. If tax refunds tend to disappear into your spending, the TFSA's simplicity might be worth the smaller long-term return.
