Crypto Tax-Loss Harvesting Canada 2026: The Rules That Matter
TL;DR
Crypto losses are deductible against capital gains. The 30-day superficial-loss rule applies — don't re-buy the same coin within 30 days. Different coins (BTC vs ETH) are different properties and don't trigger the rule. Use the loss harvest before Dec 31.
The framework in 60 seconds
- Identify positions with unrealized losses (current value < ACB)
- Sell to realize the capital loss
- Wait at least 31 days before re-buying the same coin (or buy a different coin / different protocol exposure)
- Use the loss to offset capital gains elsewhere in 2026, or carry back/forward
The superficial-loss rule, step-by-step
Under ITA s.40(2)(g)(i) + s.54, your capital loss is denied if both:
- You (or an affiliated person — spouse, controlled corp) acquire the identical property in the period from 30 days before to 30 days after the disposition
- You (or an affiliated person) still own the substituted property at the end of that 30-day post-period
If the rule fires, the denied loss is added to the ACB of the new holding — you'll eventually realize it when you sell the substitute, but you can't use it now.
Worked example — BTC harvest done right
- You hold 0.5 BTC with ACB $30,000 (avg $60K/coin), now worth $25,000
- You sell on Dec 15 → realize a $5,000 capital loss
- You wait until Jan 15 (≥31 days) before rebuying BTC
- The $5,000 loss offsets your other 2026 capital gains at the 50% inclusion rate (or 66.67% above $250K of total gains)
- If you have no 2026 gains, carry it forward or back via Form T1A
Worked example — superficial-loss trap
- Same setup, sell Dec 15 for a $5,000 loss
- You buy back 0.5 BTC on Dec 20 (within 30 days)
- You still hold it on Jan 14
- The $5,000 loss is denied — added to the ACB of the new BTC instead
- No deduction this year
Substitution strategies that work
- Different coin: sell BTC, buy ETH — fully compliant. They're different properties.
- Different protocol exposure: sell SOL, buy AVAX
- Bridging asset: sell BTC at loss, hold stablecoin for 31 days, then re-buy BTC
- Take the cash: harvest, hold CAD, redeploy in 2027
Wrapped versions (e.g. WBTC) are technically a different property but CRA's view on substitutes that track the same underlying is unsettled — be cautious.
Tracking ACB across the rebuy
The denied loss adds to the ACB of the substituted property. You don't lose the deduction permanently — it shifts in time. Your ACB calculator should track this carefully, or you'll double-count later.
2026-specific planning notes
- Inclusion rate cliff at $250K: if you've already realized $250K+ of capital gains in 2026, the next dollar of harvested loss saves at the 66.67% inclusion rate — extra valuable.
- Carryback to recover prior tax: if 2023, 2024, or 2025 had heavy gains and you paid CRA, harvest in 2026 and carry back via T1A.
- Year-end timing: dispositions on Canadian exchanges settle instantly, but aim for mid-late December to avoid year-end congestion.
Filing
Report the disposition on Schedule 3 alongside other capital dispositions. The taxable portion of net capital gains/losses flows to T1 Line 12700. For full T1 mechanics see our T1 walkthrough.
