Canada Crypto Tax Loss Harvesting 2026

Tax-loss harvesting is a year-end strategy Canadian investors use to reduce their capital gains tax bill. Sell a coin that has fallen below its adjusted cost base, and you realize a capital loss, which offsets capital gains on any other crypto, stock, or property you sold that year.

The CRA lets you carry those losses back for up to three years or forward indefinitely. It also enforces the superficial loss rule, which denies the deduction if you or an affiliated person buys the same coin back inside a 61-day window and still holds it when the window closes.

The CRA treats crypto as a commodity, so most investor trades are dispositions of capital property. Gains and losses go on line 7 of Schedule 3, the crypto-assets line.

Half of a capital loss is an allowable capital loss, and half of a capital gain is a taxable capital gain. Because both sides are halved, a $10,000 loss cancels a $10,000 gain in full. The 50% inclusion rate still applies for 2026. The proposed increase to 66.67% was deferred on January 31, 2025, and canceled on March 21, 2025, and it never took effect.

If allowable losses exceed taxable gains for the year, the excess is a net capital loss. Carry it back to any of the three prior years using Form T1A, or carry it forward indefinitely. No election is needed to carry a loss forward, and your Notice of Assessment tracks the unused balance.

If the CRA decides you trade in a commercial manner, based on frequency, leverage, holding period, and how you present the activity, your crypto moves to the income account. There, 100% of gains and losses count, losses can offset other income, and the superficial loss rule does not apply because inventory is not capital property. The burden of proof sits with the taxpayer.

A capital loss is the amount by which your proceeds of disposition, less outlays and expenses, fall short of the coin's adjusted cost base. Selling does not reset the ACB to zero. Because the CRA pools identical property, selling part of a holding removes a proportionate share of the pooled cost, and the remaining units keep the same per-unit ACB.

If you or an affiliated person buys the identical coin within 30 days before or after the sale and still holds it at the end of that period, the superficial loss rule denies the loss. The denied amount is added to the ACB of the newly acquired units, so the deduction is deferred rather than erased.

Traders and businesses on income account run the same calculation but report it on Form T2125 or a corporate return, where the full amount counts. You do not get to pick which account applies. The CRA looks at how you actually traded, and it rarely lets anyone reclassify a year after filing it.

Yes. The CRA accepts that selling property to realize a real loss is permitted, provided the transaction has economic substance, and you actually give up ownership. What you cannot do is buy the identical property back inside the 61-day window and still hold it at the end.

If you want market exposure during the gap, hold something clearly different. Sell BTC and buy ETH and you are fine, but sell BTC and buy wrapped BTC on Ethereum, and you are not. A spot Bitcoin ETF is the hard case. It is a different security, it holds bitcoin, and the CRA has published nothing on where it draws that line for crypto. If you use an ETF as a placeholder, know that you are taking a position the CRA has not blessed, and write down why you think it holds.

Buying the replacement inside your TFSA, RRSP, FHSA, or RRIF does not sidestep the rule. Registered plans count as affiliated persons. The CRA denies the loss, and because the plan is not taxable, you never get the deduction back on a later sale.

Tax-loss harvesting means finding coins trading below your ACB, selling them to lock in the capital loss, then staying out of that coin for 31 days. The CRA's test is identical property, not correlation, so you can hold a different coin in the meantime without breaking the rule. The harvested loss reduces your gains on other crypto, stocks, ETFs, or property sold in the same year. If your allowable capital losses exceed your gains, carry the unused amount back up to three years or forward indefinitely.

The CRA pools identical property, so your ACB depends on every purchase you have ever made in that coin, across every wallet and exchange. Acquisition costs and transaction fees all convert to Canadian dollars at the rate on the day. One wallet transfer logged as a sale will throw off the pool and misstate every gain and loss that follows it. Reconcile your history before you start harvesting, not after.

1. Compile your full transaction history. Export CSV files or connect APIs for every exchange and self‑custody wallet.

2. Calculate ACB per asset. Convert each acquisition cost to CAD at the CRA‑accepted spot rate on the date received.

3. Identify loss positions. Flag coins whose current market value is below their ACB pool.

4. Check the superficial loss clock. Confirm that neither you nor an affiliated person, including your spouse, a corporation you control, or your own TFSA or RRSP, bought the same coin in the previous 30 days, and that none of you will buy it in the 30 days after the sale.

5. Sell by December 31. Crypto trades on an exchange settle immediately, so the trade date is the disposition date and there is no settlement lag to plan around. The exception is a Canadian-listed crypto ETF in a brokerage account, which settles T+1 and needs to be traded by roughly December 30.

6. Document proceeds and fees. Save trade confirmations and blockchain transaction IDs. The CRA expects you to keep records for six years from the end of the tax year they relate to.

7. Wait until day 31 after the sale to rebuy. If you want exposure in the meantime, hold something that is not identical property.

The rule catches you when you sell property at a loss, you or an affiliated person acquires identical property during the 61-day window that runs from 30 days before the sale through 30 days after, and that property is still held when the window closes.

Affiliated persons include your spouse or common-law partner, a corporation you or your spouse controls, and your own registered plans, including a TFSA, RRSP, FHSA, or RRIF. A repurchase by any of them counts as if you made it yourself.

Section 54 never mentions crypto. It doesn't need to, because the CRA treats digital assets as property and the rule applies to property. What section 54 doesn't do is define identical property for crypto, and the CRA has published no list. Bitcoin and wrapped bitcoin would be hard to argue apart. Bitcoin and ether are obviously different coins.

A loss is only claimable when there is a disposition. A token that has collapsed to a fraction of a cent but still sits in your wallet has not been disposed of, so there is nothing to report yet. Selling or swapping it, even for a trivial amount, creates the disposition.

For tokens with no market at all, there is no clean mechanism. Subsection 50(1) of the Income Tax Act allows a taxpayer to elect to treat certain property as disposed of for nil proceeds, but it was written for bad debts and shares in insolvent corporations, and crypto doesn't obviously fit either. Your practical option is to actually dispose of the token at whatever nominal price you can get.

Crypto lost to a compromised wallet, a lost seed phrase, or a bankrupt exchange is a separate question. The CRA has not issued guidance on any of the three. In a bankruptcy, the year you claim the loss usually depends on when your claim against the estate becomes final, not the day the platform froze withdrawals. Keep records of what you held, when access ended, and what you recovered.

Two core requirements govern loss claims. First, you calculate ACB by pooling identical property, which the CRA requires, rather than using FIFO or specific identification. Second, you keep records that let someone else rebuild the number: trade IDs, wallet logs, exchange receipts, and the CAD conversion rate you used on each transaction.

Airdropped and forked coins are not deductible while you still hold them, the same as any other property. When you dispose of them, their ACB is in dispute. The CRA has not said whether airdrops carry a nil cost or fair market value at the time of receipt, and the answer affects the size of your loss. Take a position, document it, and be ready to explain it.

Staking and mining rewards are more settled. They enter the pool at their fair market value in Canadian dollars on the day they land in your wallet, and that value is also income to you when you receive them.

Harvesting cuts the tax you owe on gains you already realized this year. If you have no gains this year but paid tax on gains in 2023, 2024, or 2025, Form T1A carries the loss back and the CRA refunds tax you already paid. That refund is cash in hand, not a deduction you wait to use.

Losses you cannot use now never expire. They sit on your CRA account until you have gains to apply them against, which makes December a reasonable time to clear out positions you no longer want regardless of your gain position this year.

Selling for tax reasons alone can cost you more than it saves. Crypto can run hard during the 31 days you are sitting out, and nothing about the tax rule protects you from that.

Harvesting too aggressively may push the CRA to argue you are on income account. That is not automatically worse, since income-account losses are fully deductible against other income, but it removes the 50% inclusion rate on your gains, and you do not get to pick when it applies.

And a repurchase inside the window denies the deduction outright. In a registered plan, it destroys it permanently.

• December 31: last day to sell crypto and have the disposition fall in the current tax year. Exchange trades settle same-day.

• Roughly December 30: last trade date for a Canadian-listed crypto ETF, which settles T+1.

• Day 31 after the sale: earliest you can rebuy the identical coin without triggering the superficial loss rule.

• April 30 of the following year: filing and balance-due deadline for most individuals.

• June 15 of the following year: filing deadline if you or your spouse is self-employed. Any balance owing was still due April 30.

TokenTax imports transactions from Canadian and offshore exchanges, self-custody wallets, and on-chain activity, then pools identical property and calculates ACB in Canadian dollars as required by the CRA. Output is a gains-and-losses report that ties to Schedule 3 totals, and the software flags repurchases that fall within the 61-day superficial loss window before you file, rather than after.

Higher-tier plans include reconciliation by accountants who prepare Canadian returns, which matters most when your history spans multiple exchanges or includes a platform that no longer exists. Either way, you end up with a transaction-level record you can hand to the CRA if they ask.

• Rebought the identical coin inside the 61-day window and still held it at the end.

• Bought the replacement in a TFSA or RRSP, which kills the deduction permanently.

• Left transfer fees and gas out of the ACB pool.

• Tracked each exchange separately instead of pooling identical property across every wallet and account.

• Realized the loss but never filed Form T1A to carry it back against gains from earlier years.
