Why a TFSA is the right home for GIC interest

Not all investment income is taxed the same way in Canada, and GIC interest sits at the worst end of the scale. Interest is taxed as ordinary income at your full marginal rate, with no preferential treatment — unlike capital gains, where only half is taxable, or eligible Canadian dividends, which get a dividend tax credit.

That is exactly why sheltering it matters. On $10,000 in a 1-year GIC at 3.40%, the interest is $340:

Over a longer term the gap compounds. $10,000 in a 5-year GIC at 4.00% grows to $12,166.53 inside a TFSA. The identical GIC held non-registered by someone at a 43% marginal rate effectively earns about 2.28% after tax and reaches roughly $11,193 — a difference of about $973 on a $10,000 deposit, for no extra risk and no extra effort.

There is a fair counter-argument worth stating: because TFSA room is limited and permanent, some people prefer to fill it with higher-growth assets and hold safe interest-bearing products outside. Both positions are defensible. The honest resolution is that if the money is going into a GIC anyway and you have unused room, there is no reason to leave the interest exposed to tax.

Do registered GICs pay a lower rate?

Generally no, and this is where a TFSA GIC differs from TFSA cash. Checking EQ Bank’s published tables in September 2026, the TFSA, RRSP and FHSA GIC rates are identical to the non-registered rates at every term — 3.40% at one year, 3.65% at two, 4.00% at five. There is no registered surcharge and no discount.

Rates do move, and quickly. Oaken Financial’s rates rose three times between July and August 2026 (its table is now effective August 21), and EQ moved too without ever updating its own published “effective” stamp — which is why we publish ranges and verification dates rather than a live table. For the current picture across banks, see our best GIC rates in Canada hub.

The lock-in trap

The TFSA’s great advantage is flexibility: you can withdraw any amount at any time, tax-free, and the room comes back on January 1 of the following year. A non-redeemable GIC removes exactly that. The tax rules still let you withdraw; the GIC contract does not.

Three consequences follow, and they catch people out in this order:

• Emergency money should not be in a locked GIC. A TFSA is many Canadians’ emergency fund. Putting that specific money into a 5-year non-redeemable GIC defeats the purpose.
• Cashable GICs cost real yield. Oaken’s 1-year cashable GIC pays 2.25% against 3.55% for the locked 1-year version — the liquidity costs you well over a point.
• Short terms are poor value right now. Oaken’s 30 to 179 day GICs pay just 1.00% to 2.25%. Money you need within months is usually better off in a high-interest savings account than a short GIC — our GIC vs HISA guide works through that decision, and the best HISA rates hub covers the savings side.

The usual fix is a ladder: split the money across one, two, three, four and five-year terms so a portion matures every year. You capture most of the longer-term rate while keeping annual access, and each maturity is a natural moment to reassess.

Contribution room, and the mistake that costs 1% a month

A TFSA GIC uses TFSA contribution room like any other TFSA holding. For 2026 the annual limit is $7,000, and someone eligible since the TFSA launched in 2009 who has never contributed has $109,000 of cumulative room, per the Canada Revenue Agency.

Two mechanics matter specifically for GICs. First, interest earned inside the TFSA does not use up room — only contributions do, so a maturing GIC that has grown does not create an over-contribution. Second, if you withdraw and want to put the money back, the withdrawn room only returns on January 1 of the following year. Re-contributing in the same year without spare room triggers a penalty of 1% per month on the excess. A GIC maturing in, say, October is exactly the situation where someone withdraws, changes their mind, and re-deposits too early.

If you are still deciding which account should hold the money in the first place, our guide to TFSA or RRSP covers the underlying choice.

Is a TFSA GIC insured?

Yes, and registered accounts get their own protection. The Canada Deposit Insurance Corporation insures eligible deposits up to $100,000 per insured category at each member institution, and registered plans such as TFSAs and RRSPs are separate categories from non-registered deposits. A TFSA GIC therefore has its own coverage rather than sharing a limit with your chequing account at the same bank.

Where people get caught is at the institution level. EQ Bank is the digital brand of Equitable Bank, and the two are a single CDIC member — deposits are aggregated, not doubled. Oaken is the opposite: it states on its own rates page that each deposit is issued through either Home Bank or Home Trust Company, “both of which are separate members of CDIC”, which can allow up to $200,000 of coverage per category for a saver who splits deliberately. Our leaves on EQ Bank GIC rates and Oaken GIC rates go through each in detail.
