Why most Canadians choose taxed savings over their TFSA

Your regular savings account pays 4.5% interest. The government takes roughly 30% of that as tax. You keep 3.15%.

Your TFSA pays the same 4.5% interest. The government takes nothing. You keep 4.5%.

That's $135 extra per year on every $10,000 saved. Over 20 years, assuming you reinvest that interest, the difference is about $3,200 per $10,000. Most Canadians know this math exists. They keep using regular savings accounts anyway.

The reason isn't ignorance. It's three persistent myths about how TFSAs work.

Myth 1: TFSAs are for investing, not saving

A TFSA - Tax-Free Savings Account - holds whatever you put in it. Cash, GICs, high-interest savings accounts, stocks, bonds. The "savings" in the name doesn't mean it only holds savings accounts.

Most major banks offer TFSA savings accounts that pay the same rate as their regular savings accounts. Same liquidity, same access, zero tax on the interest. The only difference is the annual contribution limit: $7,000 for 2025, with cumulative room of $102,000 if you've been eligible since 2009.

Myth 2: You lose TFSA room if you withdraw

You get it back. Not immediately - on January 1st of the following year. So if you withdraw $5,000 in March, you can re-contribute that $5,000 starting next January, plus your new annual room.

This isn't true for RRSPs. RRSP room disappears when you withdraw. TFSA room comes back. The confusion between the two accounts keeps people in taxable savings "just in case."

Myth 3: The tax savings don't matter for small amounts

At 4.5% interest, every $1,000 in a regular savings account costs you about $14 per year in unnecessary tax. At Ontario's marginal rates around $70,000 income, that's roughly 31% of your interest gone.

Across $25,000 in savings - a reasonable emergency fund - you're paying $350 annually to keep money outside your TFSA. That's one monthly groceries bill. TaxSplit.ca shows the exact cost for your income and province.

The real barrier isn't the account

It's the paperwork shuffle. Most people have their paycheque going into their main chequing account at Bank A. Their savings sit at Bank A too, in a regular savings account, because moving money between institutions feels like effort.

The path of least resistance keeps them paying tax on interest they don't need to pay tax on.

Banks don't mind this arrangement. They collect the same deposits either way. Tax-free interest helps you more than it helps them. The reminder emails aren't coming.

What the catch is

TFSA over-contributions get penalized at 1% per month. So if you accidentally put in $8,000 when your room was only $7,000, that extra $1,000 costs you $10 monthly until you withdraw it.

The CRA tracks your room, but they're not real-time. If you've made withdrawals or have unused room from previous years, you need to know your number before you contribute. Your latest Notice of Assessment shows the total.

If you're starting fresh with no previous TFSA contributions and were a Canadian resident at 18 or older since 2009, you have $102,000 of room. For most emergency funds, that's more than enough buffer.

Set up the TFSA savings account. Transfer the money. Same access, same flexibility, 30% more interest in your pocket instead of the government's.
