Selling a losing stock in your regular investment account and buying it right back inside your TFSA or RRSP feels like a clean fix: realize the tax loss on one side, keep the investment — tax-sheltered, even better — on the other. The Income Tax Act's superficial loss rule does not see it that way. In this specific situation, the outcome can be worse than an ordinary superficial loss, because the tax benefit can be permanently lost rather than simply delayed.
This article explains why a registered-account repurchase still counts, why it behaves differently from a repurchase in a regular account, and what to do instead if you want the investment inside your TFSA or RRSP.
Registered Accounts Don't Get a Pass
The superficial loss rule looks at whether you — or a person affiliated with you — reacquire the same or an identical property within the restricted period surrounding your sale, and still hold it at the relevant time. Nothing in that test cares which account holds the repurchased shares. A purchase inside your own TFSA or RRSP is still a purchase made by you for this purpose, exactly as if you had bought the shares back in your regular brokerage account.
Why This Version of the Rule Is Worse
In most ordinary superficial loss situations, the denied loss isn't gone — it is added to the adjusted cost base of the shares you reacquired, so the benefit surfaces later when you eventually sell those shares to someone unaffiliated with you. That deferral mechanism depends on the repurchased shares having a trackable adjusted cost base outside a registered plan.
| Where the repurchase happens | What typically happens to the denied loss |
|---|---|
| Your own non-registered account | Generally added to the adjusted cost base of the repurchased shares — deferred, recoverable later |
| A spouse's non-registered account | Generally added to your spouse's adjusted cost base — deferred within the household |
| Your own TFSA or RRSP | The adjusted-cost-base mechanism does not carry into the registered plan, so the denied loss can be permanently lost with no future offset |
Because a TFSA or RRSP does not track adjusted cost base for shares held inside it the way a taxable account does, there is no clean place for the deferred loss to attach. For many investors, the practical result is that the loss simply disappears.
Why the Rule Works This Way
TFSAs and RRSPs are built around a different tax model entirely — contributions, withdrawals, and internal growth are tracked, but capital gains and losses on individual holdings inside the plan are not reported or adjusted the way they are in a taxable account. A denied superficial loss has nothing to attach to once it crosses into that structure, and the Income Tax Act does not create a special mechanism to preserve it there. Investors who assume a registered account sits entirely outside the CRA's view for this purpose are working from a mistaken premise.
How to Actually Move an Investment Into a Registered Account After Selling at a Loss
- [ ] Sell the losing position in your non-registered account first.
- [ ] Wait out the full restricted period the Income Tax Act sets before buying the same or an identical security anywhere — including inside your TFSA or RRSP.
- [ ] If you want the exposure sooner, consider a genuinely different investment for the registered account in the meantime, rather than the identical security.
- [ ] Confirm the current rules and exact timing with a tax professional before you place the registered-account purchase — miscounting the window is the most common way this trap gets sprung.
Frequently asked questions
Does this apply the same way to a spousal RRSP?
A spousal RRSP is still an RRSP for this purpose, and it can also raise the separate affiliated-persons issues that come up with any spousal account. Get specific advice before assuming either the registered-account rule or the spousal rule applies more narrowly than it does.
If I sell inside my TFSA at a loss, can I at least deduct that loss against other income?
No. Losses realized inside a TFSA are not deductible at all, against any income, regardless of the superficial loss rule. That is a separate and even less forgiving issue from the one covered here, which addresses selling in a taxable account and repurchasing inside a registered plan.
Is there any way to fix this once the registered-account purchase has already happened?
Once the statutory conditions are met and the repurchase has occurred inside the registered plan, the denied loss generally cannot be recovered after the fact. Avoiding the trap before you trade is far more reliable than trying to correct it afterward.
Does the same permanent-loss risk apply to an FHSA or RESP?
The core problem — no adjusted-cost-base mechanism inside the plan to carry a deferred loss — can apply to other registered accounts as well. Confirm the treatment for your specific plan type with a tax professional before assuming it works the same as a TFSA or RRSP.
