A Non-Qualified Investment in a TFSA Costs 50% of What You Paid, Before Any Tax on the Gain
A tax-free savings account has one job: no tax. Buy the wrong holding and that promise inverts. In our worked example below, a single TFSA position that turns out not to qualify costs $5,924.00 in federal tax alone if the refund is denied, against $594.00 for the identical position held in a plain non-registered account at the top federal bracket, 9.97 times as much, on a position that only returned $2,800.00 in total. No trading and no business carried on inside the plan is required. Just one wrong holding.
Subsection 146.2(6) of the Income Tax Act has two limbs. Our companion piece covers the first: a TFSA that carries on a business. This piece is the second, and it needs nothing so active. It needs the trust to hold, at any time, a property that is a non-qualified investment. Our TFSA rules guide sets out the account’s limits, room and penalties in outline. This piece takes the single rule that decides what the account is allowed to own, and follows it through to the bill. The Act discussed below is quoted as current to September 3, 2026, and was last amended June 18, 2026.
The whitelist, not a blacklist
ITA 207.01(1) defines a non-qualified investment as property that is not a qualified investment for the trust. Nothing is named as forbidden; everything is forbidden unless it appears on the list of what qualifies. The clause that matters most to a retail investor is paragraph (d) of the qualified investment definition in section 204, picked up by 207.01(1)(a): securities listed on a designated stock exchange, other than futures contracts or other derivative instruments where the holder’s risk of loss can exceed the cost. That carve-out matters here because the Montreal Exchange, which lists derivatives, is itself one of the designated exchanges: being listed there does not automatically qualify a derivative position.
Only the Minister of Finance decides which exchanges are designated, and the designation is not fixed. Under ITA 262, the Minister may also revoke a designation, and a revocation can take effect before it is made. The Department of Finance’s published list therefore names exchanges “that are or at any time were” designated, a history as well as a current record, and the Minister can designate “a part of” an exchange, which is how the TSX Venture Exchange comes to be listed by tier. Canadian exchanges on the list include the Montreal Exchange, the Toronto Stock Exchange, the TSX Venture Exchange (both tiers), the Canadian Securities Exchange, and Cboe Canada. American exchanges on it include Nasdaq, the New York Stock Exchange, NYSE American, NYSE Arca, and several others. No over-the-counter market is on the list; OTC Markets, OTCQX, OTCQB and the Pink tiers do not appear.
That is not the end of the test. Regulation 4900(1)(w) prescribes an American Depositary Receipt as a qualified investment where the property the receipt represents is listed on a designated exchange. So the question for a US-quoted holding is not where the receipt itself trades, it is whether the underlying share clears the exchange test. A stock quoted only over the counter, with no ADR structure and no designated-exchange listing behind it, is the trap; an ADR over a company listed on a designated exchange is not, whatever tier the receipt trades on.
The list also covers money and deposits within the meaning of the Canada Deposit Insurance Corporation Act or held at a Canadian bank branch, GICs issued by a Canadian trust company, and a handful of narrower categories under Regulation 4900: shares and debt of public corporations other than mortgage investment corporations, units of mutual fund trusts, and gold or silver bullion. Bullion qualifies only when the bar or coin meets a minimum fineness and was produced by the Royal Canadian Mint or a refiner on the London Bullion Market Association’s good delivery list. Separately, it must also be acquired directly from the Mint, the refiner, or another approved corporation such as a Canadian bank or trust company. A coin or bar can satisfy one condition and fail the other.
What the test does not catch: small caps and delisting
The exchange test excludes Canadian small caps less than it might seem: names trading on the TSX Venture Exchange or the Canadian Securities Exchange clear it on their own, the kind of companies on our ranked Canadian penny stocks page.
There is a counter-intuitive exception worth knowing before assuming the worst. CRA Income Tax Folio S3-F10-C1, paragraph 1.21, says that shares of a corporation resident in Canada, listed on a designated exchange in Canada, generally retain their qualified investment status even after being suspended from trading or delisted, because the corporation continues to be a public corporation. A Canadian holding falling off the TSX does not, by itself, flip it to non-qualified. The folio says “generally,” and it applies to a corporation resident in Canada. It is not a blanket rule and it does not extend to foreign companies.
The first tax: 50%, and it is personal
If a registered plan acquires a non-qualified investment, ITA 207.04(1) makes the controlling individual, personally, liable for a tax, and 207.04(2) sets the amount at 50% of the fair market value of the property at the time it was acquired. That charge is separate from anything the plan itself owes, and it falls on the individual, not the trust.
The 50% charge is not only for a non-qualified investment. Section 207.04(1) taxes “a prohibited investment, or a non-qualified investment” the same way, so clearing the listing test is not a clean bill of health on its own. A prohibited investment includes a share, interest or debt connected to a corporation, partnership or trust in which the holder has a “significant interest,” broadly 10% or more of any class of shares under the specified shareholder test, or to a person not dealing with the holder at arm’s length. Where a holding is both prohibited and non-qualified, ITA 207.04(3) treats it as the prohibited investment, not the non-qualified one. That deeming applies for the purposes of 146.2(6) as well, so it does more than break a tie: it takes the holding off the non-qualified route entirely. The second tax described below, and the 90-day notice after it, are the consequences of the non-qualified route. A holding sent down the prohibited route by 207.04(3) still carries the 50% charge, but what follows is different: income and capital gains attributable to a prohibited investment are an advantage under paragraph (c)(i) of the 207.01(1) definition, taxed at 100% rather than charged to the trust.
The charge also catches a holding that goes bad after purchase. ITA 207.01(6) deems the trust to have disposed of the property immediately before it becomes non-qualified, at fair market value, and reacquired it at the same value, so a security that was listed on a designated exchange when bought and later loses that status can trigger the same 50% tax at the moment it changes.
The 50% tax is also not limited to TFSAs. ITA 207.04(1) charges it against “a registered plan,” and ITA 207.01(1) defines a registered plan as a FHSA, RDSP, RESP, RRIF, RRSP or TFSA. The same charge, the same refund and the same two grounds for losing it, covered next, reach a non-qualified investment held in any of those accounts, with 207.04(5) apportioning a refund where more than one person can claim it, and 207.04(6) adding joint liability where an RDSP has more than one holder or an RESP more than one subscriber. The second tax has parallels too. Subsection 146.2(6) is the TFSA’s, and each other plan has its own: 146(10.1) for an RRSP, 146.1(5) for an RESP and 146.3(9) for a RRIF each charge the trust on what its taxable income would be from the non-qualified property alone, in almost the same words, and 146.4(5) and 146.6(3) do the same for an RDSP and an FHSA. Those are the six subsections 207.04(3) and (7) operate by reference to. Worth noting for anyone reading our companion piece alongside this one: the RRSP’s business-income charge is in 146(4)(b), while 146(10.1) is the non-qualified investment charge. Different limbs, different subsections. The worked example below runs on the TFSA numbers.
The refund, and what makes “ought to have known” bite
The 50% tax can come back. ITA 207.04(4) entitles the holder to a refund equal to the tax paid if the property is disposed of before the end of the calendar year following the year the tax arose, or any later time the Minister considers reasonable in the circumstances. The refund is nil, though, if it is reasonable to consider that the holder knew, or ought to have known, at acquisition, that the property was or would become non-qualified.
The more carefully a holder researched a security before buying it, the harder it becomes to argue afterward that they did not know what it was quoted on. Diligence is what makes this ground bite: a holder who can show they looked into a company and genuinely missed the exchange question is in a different position than one who knew the stock traded over the counter and bought it anyway.
The refund’s two grounds are independent, not sequential
The two grounds for losing the refund do not work as one hurdle to clear. Selling before the deadline satisfies 207.04(4)(b)(ii), the timing ground, on its own, and that ground is not even absolute: the subsection allows the deadline to run to “any later time that the Minister considers reasonable in the circumstances.” Clearing it does nothing about 207.04(4)(b)(i), the knowledge ground, which tests what the holder knew or ought to have known “at the time the property was acquired by the trust.” A holder who sells the moment they discover the problem has met the timing condition and can still be refused the refund, because the knowledge ground looks back to the purchase and is unaffected by what happened afterwards. Selling in time protects the refund from one ground. It does not reach the other.
The second tax: inside the plan, and it is Part I income tax
Holding a non-qualified investment also strips the TFSA’s usual exemption from Part I tax on income and gains from that property, under ITA 146.2(6). Paragraph 146.2(6)(b) removes the half inclusion that paragraph 38(a) would otherwise give: the trust’s taxable capital gain equals the full capital gain. Our guide to how investment income is taxed in Canada works through what that half inclusion is worth on an ordinary gain, and this paragraph withdraws it. This tax is paid by the trust itself, at the top personal rate under ITA 122(1)(a), 33% for 2026, from the first dollar; there is no bracket structure for a trust taxed this way.
Unlike the business limb of 146.2(6), where 146.2(6.1) makes the holder jointly and severally liable, there is no equivalent provision here: the Part I tax on a non-qualified investment comes out of the plan and stays there. That is gentler than the business limb, but only up to a point. Ignore the 90-day notice described below, and the resulting advantage tax becomes a personal liability after all.
The worked example
The position: a TFSA buys a stock quoted only over the counter in the United States, never listed on any designated exchange.
| Line | Amount |
|---|---|
| cost, 2026-03-02 | $10,000.00 |
| proceeds, 2027-05-04 | $12,000.00 |
| capital gain | $2,000.00 |
| dividends, 2026 | $400.00 |
| dividends, 2027 | $400.00 |
| total return over the holding | $2,800.00 |
Federal tax only. The 50% tax under 207.04(2) is 50% of the $10,000.00 acquisition cost: $5,000.00, payable by the holder personally on Form RC243, before July 2027.
Inside the plan, under 146.2(6), the 2026 dividends of $400.00 are taxed at 33%: $132.00. The 2027 capital gain of $2,000.00 is fully included under 146.2(6)(b), added to nothing else, giving 2027 taxable income of $2,400.00, taxed at 33%: $792.00. Part I tax across both years: $924.00. Had the ordinary half-inclusion rule applied instead, the 2027 taxable income would have been $1,400.00 and the tax $462.00, so 146.2(6)(b) alone costs an extra $330.00 on this position.
If the position is sold on 2027-05-04, that disposal falls inside the calendar year after the year the tax arose, satisfying 207.04(4)(b)(ii), so the 50% tax is refunded. Total federal tax in that case: $924.00.
If the refund is denied under 207.04(4)(b)(i), total federal tax is $5,924.00, which is 2.12x the $2,800.00 the position actually returned.
The same holding in a plain non-registered account, federal tax only, under the ordinary half-inclusion rule:
| other taxable income | federal marginal rate | federal tax on this position |
|---|---|---|
| $0 | 14.0% | $252.00 |
| $60,000 | 20.5% | $369.00 |
| $120,000 | 26.0% | $468.00 |
| $200,000 | 29.0% | $522.00 |
| $300,000 | 33.0% | $594.00 |
Even at the top federal rate, the plain taxable account costs $594.00. The TFSA with the refund denied costs $5,924.00, almost ten times as much, 9.97x by our arithmetic, for holding the identical position in the account built to be tax-free.
The 90-day notice and the advantage tax
The exposure does not stop at the two taxes above. ITA 207.06(4) lets the Minister notify the holder that a payment must be made out of the plan within 90 days, of at least the “specified non-qualified investment income,” meaning income or a capital gain attributable to an amount already taxed under Part I inside the plan. Ignoring that notice has its own consequence. Under the definition of “advantage” in 207.01(1)(b)(iv), specified non-qualified investment income not paid out within 90 days of the notice becomes an advantage, and ITA 207.05(1) and (2)(a) impose a tax equal to 100% of its fair market value, not 100% of the account, 100% of the income or gain named in the notice.
That 100% tax is a personal liability. Under ITA 207.05(3), each controlling individual of the plan is jointly and severally liable to pay it, unless the issuer, carrier or promoter of the plan itself extended the advantage, in which case the issuer is liable instead. So a tax that starts inside the plan, at 146.2(6), can still land on the holder personally if a 207.06(4) notice is ignored.
Routes that qualify, and the condition each turns on
| Route | Provision | The condition it turns on |
|---|---|---|
| Listed securities | ITA 204(d) via 207.01(1)(a) | Listed on a designated stock exchange. Futures and other derivatives where the holder’s risk of loss can exceed cost are excluded even when listed |
| American Depositary Receipts | Reg 4900(1)(w) | The property the receipt represents, not the receipt itself, is listed on a designated exchange |
| Public company shares and debt | Reg 4900(1)(b), (c.1) | The issuer is a public corporation, and is not a mortgage investment corporation |
| Mutual fund units | Reg 4900(1)(d) | The vehicle is a mutual fund trust as the Act defines it, not merely a fund sold to the public |
| Deposits and GICs | ITA 204(a) for deposits, 204(f) for GICs | A bank-issued GIC or deposit travels the deposit route in 204(a); 204(f) covers certificates issued by a Canadian trust company |
| Gold and silver bullion | Reg 4900(1)(t), (u) | Minimum fineness, production by the Royal Canadian Mint or an LBMA good-delivery refiner, and acquisition directly from an approved source, are three separate conditions and all must hold |
| Any holding connected to the plan holder | ITA 207.01(1) definition, with the threshold in 207.01(4) | A 10% or greater interest in the issuer, or a non-arm’s-length connection, makes it a prohibited investment however it is listed |
The securities lending fix
A related problem was fixed in 2026, backdated to January 1, 2023. When a registered plan lends out a security, the right it receives back is not itself named on the qualified investment whitelist. A new subsection 207.04(7) deems that right not to be non-qualified, provided several conditions hold: the security lent is itself listed on a designated exchange, the borrower is a registered securities dealer resident in Canada, the trust has the right to require an identical security back at any time, equivalent-value collateral is held in trust for the lender, and the holder received written disclosure and consented before the arrangement began.
What a reader does with this
Before buying anything inside a registered plan, both the whitelist and the prohibited-investment tests apply, and only one of them is anybody else’s job. ITA 207.01(5) puts the issuer, carrier or promoter of the plan under a statutory duty to exercise the care, diligence and skill of a reasonably prudent person to “minimize the possibility that a trust governed by the registered plan holds a non-qualified investment”, so a blocked order is that duty in the statute rather than an arbitrary restriction. That duty stops at non-qualified investments, the whole whitelist. It says nothing about prohibited investments, and it could not: whether a holder owns 10% of an issuer, or deals with it at arm’s length, turns on facts the broker does not have. That test is the holder’s alone.
If a non-qualified investment slips through, the RC243 return and payment are due before July of the following year, and the trustee separately owes a T3RET no later than 90 days after the calendar year ends. Selling before the following year-end preserves the possibility of a refund, but only the possibility, as the previous section shows.
Nothing here is automatic, either way. Under 207.06(1), the TFSA over-contribution waiver requires both a reasonable error and distributions made without delay covering the excess and any income attributable to it. Under 207.06(2), the waiver for a non-qualified or prohibited investment weighs reasonable error as one factor among “all the circumstances,” alongside whether the same transaction produced another tax and how much has already been paid out of the plan. Both provisions use “may.” Neither obliges the Minister to grant relief. For a specific holding, whether it qualifies rests on the reader’s own facts and is worth confirming with a tax professional.
