Does the superficial loss rule apply inside a TFSA, RRSP, or FHSA?

Losses arising wholly inside these registered accounts are not deductible. More importantly, a purchase in your TFSA, RRSP, or FHSA can cause a loss from your taxable account to be denied, and that tax benefit may be permanently unusable.

Canada's superficial loss rule: the 61-day test for investors

Q: How long must I wait to rebuy a stock after selling it at a loss in Canada?

The acquisition window starts 30 calendar days before the disposition and ends 30 calendar days after it. If July 14 is the disposition date for tax purposes, August 14 is the first day outside the post-sale window. Investors also need to check affiliated persons and purchases in the 30 days before the sale.

Q: Is a superficial loss gone forever?

Usually it is deferred rather than permanently lost. The denied amount can generally be added to the adjusted cost base of the taxable replacement property. A replacement acquired in a TFSA, RRSP, or FHSA is a major exception because the tax benefit can be permanently unusable.

Q: Can my spouse trigger my superficial loss?

Yes. A spouse or common-law partner is an affiliated person for this rule. Their acquisition of the same or identical property during the window can make some or all of your loss superficial if the replacement property is still owned at the end of the window.

By Ryan Billings

If you sell a stock or ETF at a loss, buying the same investment back too soon can stop you from claiming that loss now. Canada's superficial loss rule looks across an inclusive 61-day window, from 30 calendar days before the sale through 30 calendar days after it. It can also catch purchases by your spouse, your controlled corporation, a dividend reinvestment plan, or your TFSA, RRSP, or FHSA.

The result is not always the same. A loss may remain fully claimable, be deferred through the adjusted cost base of a taxable replacement, or become permanently unusable when the replacement is inside a TFSA, RRSP, or FHSA. The account and the buyer matter as much as the date.

Important: General education only. Not financial, tax, legal, accounting, or investment advice. Superficial-loss calculations can depend on every account, owner, purchase, sale, and reinvestment in the window. Confirm a planned transaction with a qualified Canadian tax professional.

The rule has two conditions, not one

Section 54 of the Income Tax Act and the CRA's capital-loss guidance set out two conditions. Both must be present:

You or an affiliated person acquires, or obtains a right to acquire, the same or an identical property during the period beginning 30 calendar days before the disposition and ending 30 calendar days after it.
You or an affiliated person still owns, or has a right to acquire, that substituted property at the end of the period.

The disposition date sits in the middle, so the inclusive window contains 61 calendar days. If July 14 is the disposition date for tax purposes, the window runs from June 14 through August 13, and August 14 is the first day outside it. Check the date used on the transaction's tax records, especially around settlement-cycle changes. Waiting only 30 days after a sale does not fix a purchase made before the sale, which is why checking both sides matters.

The second condition prevents a purchase inside the window from automatically tainting the loss forever. If the substituted property is no longer owned at the end of the window, the statutory test may not be met. That path can create another gain or loss and more transaction costs, so it is not a shortcut to use without reviewing the full sequence.

One sale, three possible tax outcomes

Assume an investor bought 100 shares for an aggregate adjusted cost base of $10,000, then sold all 100 for $7,000 on July 14. Ignoring selling costs, the economic loss is $3,000. The tax result depends on what happens around that sale.

What happens	Likely treatment	Where the $3,000 goes
Neither the investor nor anyone affiliated with them acquires the same or identical property in the window	Not a superficial loss	Available under the normal capital-loss rules
The investor repurchases 100 identical shares in a taxable account on August 1 and still owns them on August 13	Superficial loss	Usually added to the replacement shares' ACB, deferring recognition
The investor's spouse makes that taxable-account purchase and holds it through August 13	Superficial loss	Generally added to the spouse's replacement-property ACB, creating cross-person tracking
The investor's TFSA, RRSP, or FHSA acquires the replacement and holds it through August 13	Loss denied	The tax benefit can become permanently unusable

The CRA says a superficial loss is not deductible in the sale year, but the person acquiring the substituted property can usually add it to that property's ACB. That higher ACB can reduce a later gain or increase a later loss. This is normally a deferral, not destruction of the loss. The registered-account outcome is harsher because ACB does not produce a deductible capital loss inside the plan. The current Income Tax Act, section 40 expressly includes FHSAs in its direct-transfer loss-denial rule, alongside TFSAs and several other registered trusts. CI Global Asset Management's tax guidance explains the same permanent-denial problem for RRSP and TFSA transfers or replacement purchases.

Your other accounts and automatic purchases count

The rule is wider than one brokerage account. The CRA lists a spouse or common-law partner, a corporation controlled by you or your spouse, certain partnerships, and certain trusts among affiliated persons. CI's technical summary notes that affiliation is narrower than ordinary family relationship: an individual is generally affiliated with a spouse or common-law partner, but not merely with a child, parent, or sibling.

A TFSA, RRSP, or FHSA trust can be within the affiliated-person net. This creates a common trap: a taxable account sells at a loss while one of those plans buys the same security. An in-kind contribution of a losing position from a taxable account to a TFSA, RRSP, or FHSA is also not a way to preserve the loss. The transfer is a disposition, and the loss can be specifically denied.

Automatic activity deserves the same review as a manual order. A DRIP that buys even a small number of identical shares during the window can create a partial superficial loss if those shares remain at the end. Recurring mutual-fund purchases, employee share plans, robo-adviser trades, and a spouse's standing orders can have the same effect. The CIBC tax and estate planning report illustrates how employee share purchases and partial holdings can trigger the rule.

A different ticker is not automatically different property

The CRA's archived interpretation bulletin IT-387R2, Meaning of Identical Properties, describes identical properties as the same in all material respects, such that a prospective buyer would not prefer one over the other. The CRA also says this is a question of fact based on the relevant details. The bulletin is archived and does not have the force of law, but it remains a useful statement of the CRA's interpretive approach.

For common shares of the same class in the same company, the answer is usually straightforward: one share is interchangeable with another. ETFs need more care. Two products can have different tickers and issuers yet follow the same benchmark. A PWL Capital research paper on Canadian-listed ETFs summarizes a CRA technical position that two index funds tracking the same benchmark may be identical property. It uses funds tracking different indexes as replacement examples, while warning that similar exposure still brings tracking difference, fees, bid-ask spreads, and market risk.

Do not rely on an old list of ticker pairs. Fund benchmarks, mandates, structures, and fees can change. Compare the current prospectus and fund facts for both products, and get tax advice when the distinction is material.

Selling part of a holding can deny part of the loss

The rule can apply even without a post-sale repurchase. Suppose shares were acquired inside the 30 days before a loss sale and some identical shares remain 30 days after the sale. The pre-sale acquisition satisfies the first condition, and continued ownership can satisfy the second.

For partial dispositions, the CRA has an administrative formula summarized by CIBC: the superficial portion is the total loss multiplied by the least of the number sold, acquired in the window, or still owned at the end, divided by the number sold. This is where DRIPs and payroll purchases can turn a seemingly clean sale into a partly denied loss. Multiple lots, owners, currencies, or corporate accounts make professional review more valuable.

A before-trade checklist

A loss should support the portfolio decision, not drive it. Selling and replacing an investment can change exposure, create spreads and commissions, or miss a rebound. TD Direct Investing's tax-loss harvesting overview frames harvesting as a non-registered-account strategy and stresses ACB, costs, and portfolio fit.

Confirm there is a tax loss. Use aggregate Canadian-dollar ACB, not the price of one purchase lot or a brokerage's performance display.
Map every owner and account. Check your taxable accounts, registered plans, controlled corporations, and your spouse or common-law partner's activity.
Look back 30 calendar days. Include DRIPs, recurring buys, option rights, payroll plans, and transfers.
Plan the next 30 calendar days. Decide whether to remain in cash or use an investment that is similar enough for the portfolio but not identical for tax purposes.
Check the end-of-window holding. The second statutory condition is ownership or a right to acquire at the end of the period.
Compare benefit with cost and risk. A tax deferral does not guarantee a better after-tax investment result.
Document the conclusion. Keep trade confirmations, ACB calculations, fund documents, exchange rates, and the reason the replacement was considered non-identical.

How the loss reaches your tax return

The CRA's current 2025 Capital Gains guide, available for the 2026 filing season, says a capital loss is proceeds minus ACB and selling expenses when that result is negative. Publicly traded share and mutual-fund dispositions are reported on Schedule 3. A T5008 can help, but the CRA says supporting records are needed to calculate capital gains and losses. Book value shown by a broker may not capture positions at other institutions, transfers, reinvested distributions, return of capital, or superficial-loss adjustments.

Allowable capital losses first offset taxable capital gains for the year. A remaining net capital loss can generally be carried back three years or forward indefinitely against taxable capital gains, according to the CRA. Applying a prior-year loss involves inclusion-rate adjustments, so retain the assessed net-capital-loss balance rather than treating the raw economic loss as a permanent dollar-for-dollar amount.

Frequently asked questions

How long must I wait to rebuy after selling at a loss?

The acquisition window runs from 30 calendar days before the disposition through 30 calendar days after it. If July 14 is the disposition date for tax purposes, August 14 is the first day outside the post-sale window. Check the date used on the transaction's tax records, pre-sale buys, and affiliated persons too.

Is a superficial loss gone forever?

Usually not. It is generally added to the ACB of the taxable replacement property, deferring recognition until a later disposition. A replacement inside a TFSA, RRSP, or FHSA is the major trap because the tax benefit can become permanently unusable.

Can my spouse trigger my superficial loss?

Yes. A spouse or common-law partner is affiliated for this rule. Their purchase can deny some or all of your loss if the same or identical property is still owned at the end of the window.

Does the rule apply inside a TFSA, RRSP, or FHSA?

A loss arising wholly inside one of these registered accounts is not deductible. The plan's replacement purchase can also deny a loss realized in your taxable account, which is why accounts must be reviewed together.
