TFSA vs RRSP at $70,000: Which account wins in Ontario

At $70,000 in Ontario, you're sitting right where the RRSP starts to pull ahead of the TFSA. Your marginal tax rate is about 30.5%, which means a $5,000 RRSP contribution puts roughly $1,525 back on your tax return. That refund is the RRSP's advantage - and the reason most financial advice says "RRSP first" once you hit this income level.

But the math isn't that simple. The RRSP gives you a tax break now, then taxes everything when you withdraw. The TFSA takes after-tax dollars now, then never taxes growth or withdrawals. Which wins depends on what tax bracket you'll be in during retirement - and that's genuinely hard to predict.

The RRSP case

Put $5,000 into an RRSP at $70k in Ontario, and you'll see about $1,525 back on your tax return. If you reinvest that refund - most people don't, but let's assume you do - you've got $6,525 working for you instead of $5,000.

The catch: when you withdraw that money decades later, it's all taxable income. If you're pulling $50,000 total in retirement, your marginal rate drops to roughly 25%. You'd keep about $4,880 after tax from that original $6,525.

The TFSA case

The same $5,000 goes into your TFSA with no immediate tax break. But whatever it grows to - $15,000, $25,000, $40,000 - comes out tax-free. No forms to file, no withholding tax, no impact on Old Age Security clawbacks.

The TFSA also gives you flexibility the RRSP doesn't. Withdraw money for any reason and get the contribution room back the following year. With an RRSP, once you withdraw, that room is gone forever.

Which wins at $70k?

In Ontario at $70,000, the RRSP usually comes out ahead - but not by much. The refund gives you more money working from day one, and most people will be in a lower tax bracket during retirement than they are now.

The tipping point sits somewhere around $60,000 to $65,000 in most provinces. Below that, the TFSA often wins because the tax refund isn't large enough to overcome the TFSA's tax-free withdrawals. Above $70,000, the RRSP pulls further ahead.

Your exact numbers will vary based on what you earned last year and which province you file in. TaxSplit.ca will show you the precise refund for your situation and help you run the comparison with your actual figures.

The honest answer: at $70k in Ontario, either account will serve you well. The RRSP probably wins on paper, but the TFSA wins on simplicity and flexibility. Max out whichever one you'll actually contribute to consistently.
