Superficial Loss

Tax

A superficial loss is a capital loss the CRA disallows because you or an affiliated person repurchased the same or identical property within 30 days before or after the sale.

The superficial loss rule stops taxpayers from selling to trigger a loss while keeping the investment. If you, your spouse, or a corporation you control buys back the same or identical property within 30 days before or after the sale, and still holds it at the end of that window, the loss is denied.

The denied loss is not lost forever, it is added to the adjusted cost base of the repurchased property, so it is recognised later when you finally sell for good. The rule commonly catches tax-loss selling near year-end and transfers between personal and registered accounts.

Example

You sell a stock for a $5,000 loss on December 20 and rebuy it on December 28. The loss is superficial and denied, but the $5,000 is added to the ACB of the repurchased shares for use on a future sale.

Superficial Loss Frequently Asked Questions

Common questions regarding our compliance workflows and service guarantees.

If you or an affiliated person buys the same or identical property within 30 days before or after selling at a loss, and holds it, the loss is denied as superficial.
No. It is added to the cost base of the repurchased property, so it is effectively deferred until you sell that property without triggering the rule again.

What Canadians Search About Superficial Loss

The questions Canadians actually search on this topic, answered plainly. Browse every question in the Canadian tax answers directory.

Federal tax is the share of income tax that goes to the federal government, charged on taxable income in graduated brackets that are the same everywhere in Canada. Your total bill is that federal amount plus your province or territory's own tax, less the credits you claim. Payroll deductions shown on a T4 cover both layers. Quebec residents receive a refundable abatement of their federal tax because Quebec opted out of certain federal-provincial programs and funds them itself; separately, Quebec also collects its provincial tax through its own return.

Non-taxable income is money you receive that never enters taxable income. Common examples are lottery and most gambling winnings, gifts and inheritances, growth and withdrawals inside a TFSA, the GST/HST credit and Canada child benefit, most life insurance death benefits, and child support under current-rule agreements. A few amounts are reported and then deducted, such as workers' compensation and social assistance, because they still affect benefit calculations, so report anything that arrives on a slip even when no tax results.

Start with total income from every source for the year, including employment, self-employment, investments and pensions. Subtract the deductions you qualify for, such as RRSP contributions, child care costs, union dues and deductible employment expenses, to reach net income. Take off any further deductions that apply at the next stage, losses carried forward among them, and what remains is taxable income, the figure the brackets are applied to. Credits reduce the tax calculated on that figure rather than the income itself.

Open the forms and publications section of canada.ca, search by form number or title, and choose the PDF for the tax year you need, because forms change from year to year and prior-year versions stay available in the same place. Most personal filers need no printed forms at all, since software approved for NETFILE builds the T1 and transmits it. Paper filers should print the version for their province or territory of residence.
