The TFSA, Explained in Plain English: How It Works, 2026 Limits & the Tax Rules That Trip People Up

What is a TFSA, really?

Think of a TFSA (Tax-Free Savings Account) as a special container for your money. You put after-tax dollars in — money you've already paid tax on through your paycheque — and from that point on, everything that happens inside the container is invisible to the taxman. Interest, dividends, and growth when your investments go up: all tax-free. When you take money out, it's tax-free too.

Despite the word "savings" in the name, a TFSA is not just a savings account. It's a type of account that can hold cash, GICs, bonds, stocks, ETFs, and mutual funds — basically the same investments you'd hold in a regular investing account. The "tax-free" part is about the account, not about earning a savings-account interest rate.

To open one, you need three things: be 18 or older, be a Canadian resident for tax purposes, and have a valid Social Insurance Number (SIN).

How is a TFSA taxed?

Here's the full tax picture, in plain language:

• Putting money in: you get no tax deduction. (This is the big difference from an RRSP, where contributions reduce your taxable income.) You contribute dollars you've already paid tax on.
• While it grows: interest, Canadian dividends, and capital gains inside the TFSA are completely tax-free. You don't report them on your tax return at all.
• Taking money out: withdrawals are tax-free, and they don't count as income. That means a TFSA withdrawal won't reduce income-tested benefits like the Canada Child Benefit, and won't trigger OAS clawback in retirement.

Annual limits: how much can you put in?

For 2026, the annual TFSA limit is $7,000 — unchanged from 2024 and 2025. The limit is indexed to inflation and moves in $500 steps, so it only rises when inflation pushes it over the next threshold.

Here's the part most people miss: your room is cumulative. Unused room from every year since you turned 18 (starting in 2009, when TFSAs launched) carries forward forever. If you were 18 or older in 2009 and have never contributed, you could put in $109,000 in 2026.

Your personal room depends on when you became eligible. Room starts building in the year you turn 18 (as a Canadian resident) — even if you never open an account. Quick examples for 2026:

• Eligible since 2009, never contributed: $109,000 of room
• Turned 18 in 2020, never contributed: $6,000 (2020) + $6,000 (2021) + $6,000 (2022) + $6,500 (2023) + $7,000 (2024) + $7,000 (2025) + $7,000 (2026) = $45,500
• Newcomer who arrived in 2024: $7,000 (2024) + $7,000 (2025) + $7,000 (2026) = $21,000 — you don't get room for years before you arrived

How do withdrawals work? (And how you get your room back)

This is where the TFSA really shines — and where most confusion lives. The rule is simple:

• You can withdraw any amount, at any time, for any reason — no tax, no penalty, no questions.
• The amount you withdraw is added back to your contribution room on January 1 of the next calendar year.

Example: You withdraw $10,000 in September 2026. On January 1, 2027, your room increases by that $10,000 — plus the new annual limit for 2027. You've effectively "borrowed from yourself" and the room comes back.

What happens if you over-contribute?

The CRA charges 1% per month on the excess amount, for every month (or part of a month) it stays in the account. Unlike an RRSP — which gives you a $2,000 buffer — the TFSA gives you zero buffer.

Example: you over-contribute by $2,000 in October and don't fix it until year-end. That's $2,000 × 1% × 3 months (Oct, Nov, Dec) = $60 in penalties. And the CRA will notice — your financial institution reports every contribution.

If it happens: withdraw the excess immediately, then file a TFSA return with the CRA to report and pay the tax. The faster you act, the smaller the bill.

How are foreign dividends taxed inside a TFSA?

Here's the wrinkle most guides bury. When a US company pays you a dividend inside your TFSA, the US government takes its cut before the money ever reaches you — a 15% withholding tax (thanks to the Canada–US tax treaty; without the right paperwork it can be 30%). Your brokerage usually handles the W-8BEN form that gets you the 15% rate automatically.

The painful part: inside a TFSA, that 15% is gone forever. In a regular taxable account, you can claim a foreign tax credit on your Canadian return to get it back. In a TFSA you can't — there's no Canadian tax to credit it against. Even the RRSP gets special treatment here: the Canada–US treaty exempts US dividends in an RRSP/RRIF from withholding entirely. The TFSA gets no such exemption.

Put simply, on a $100 US dividend:

TFSA vs. a regular taxable account: what does "tax-free" actually save you?

An illustration makes it concrete. Imagine you invest a $50,000 lump sum, it grows at 6% per year for 20 years, and your marginal tax rate is 40%:

For tech employees & DIY investors: moving company shares into your TFSA

A situation I see often: you work in tech, your RSUs or ESPP shares vest into a non-registered account at Wealthsimple or Questrade, and your TFSA sits empty. Every dollar of growth on those shares is taxable. Moving them into your TFSA — where future growth is tax-free — is one of the highest-value moves you can make. Here's exactly how it works.

Your two options

Option A — Sell, then contribute the cash. Sell the shares in your non-registered account, then contribute the cash to your TFSA (as long as you have room) and rebuy — or buy something else. Simple, and it works at any brokerage.

Option B — Transfer "in-kind." Move the shares directly from your non-registered account into your TFSA without selling. Most brokerages, including Wealthsimple and Questrade, support this — look for "transfer in-kind" or "contribute shares." You keep the exact same shares; only the account wrapper changes.

Either way, you need enough contribution room to cover the full market value of what you're moving in.

The tax catch you must know: the "deemed disposition"

When shares move from your taxable account into your TFSA, the CRA treats it as if you sold them at their current market price — even though you didn't actually sell. This is called a deemed disposition. What it means in practice:

• If the shares went up: you owe capital gains tax on the profit (only 50% of the gain is included in your income — the capital gains inclusion rate). The tax is due for the year of the transfer.
• If the shares went down: you cannot claim the capital loss. The tax rules specifically deny losses on transfers into a TFSA or RRSP. The loss simply vanishes.

Example: you hold 100 shares. Your adjusted cost base is $40/share ($4,000 total) and they're now worth $65/share ($6,500 total). Transfer them in-kind → $2,500 capital gain → $1,250 added to your taxable income. The transfer counts as a $6,500 TFSA contribution, so you need at least $6,500 of room.

A practical checklist before you move shares

1. Confirm your room. Check CRA My Account and your own records. The transfer counts as a contribution at the shares' market value on the transfer date.
2. Know your cost base. For RSUs, your cost is generally the market value at vesting (you already paid tax on the employment benefit then). Your brokerage statement shows it.
3. Estimate the tax. Gains × 50% inclusion × your marginal rate = roughly what you'll owe next April. Don't let the tax bill surprise you.
4. Pick your method. In-kind keeps you invested with no time out of the market; selling first gives you a clean break and lets you harvest losses.
5. Watch the calendar. A transfer in December vs. January lands the tax bill in different tax years — worth thinking about if the gain is large.

More things worth knowing about TFSAs

You can have more than one TFSA

There's no limit on the number of TFSA accounts — you could have one at your bank and one at Questrade. But the contribution limit applies to all of them combined. Contributing $3,500 to two different TFSAs = $7,000 total, not $7,000 each.

TFSA vs. RRSP — the 30-second version

Neither is "better" — they do different jobs. A very rough rule of thumb: if you're early in your career or want flexibility, lean TFSA; if you're in a high tax bracket now and expect lower income in retirement, lean RRSP. Most people benefit from using both.

If you leave Canada

You stop accumulating new room for any year you're a non-resident, and contributing while non-resident triggers the 1%-per-month penalty. But your existing TFSA keeps growing tax-free in Canada (your new country of residence may tax it, though — worth checking).

Name your spouse as successor holder

If you name your spouse or common-law partner as the successor holder, your TFSA passes to them on death with its tax-free status intact — no deemed disposition, no tax. Without this designation, the account is deemed disposed at death. It's a two-minute form at your brokerage, and one of the most-overlooked TFSA moves.

Don't day-trade inside it

If the CRA decides you're carrying on a business — e.g., aggressive day trading — the profits can be taxed as business income even inside a TFSA. A TFSA is for investing, not for running a trading business.
