Bitcoin Tax in Canada: Capital Gains, ACB, Mining and GST/HST

Ask about Bitcoin tax in Canada and you get asked back for a rate. Wrong first question. The Canada Revenue Agency (CRA) has never written a rule called "the Bitcoin tax": the same bitcoin (BTC) is capital property for one taxpayer, business inventory for a second and mining income for a third.

Character comes before calculation: the amount, the schedule and the records all move with the characterisation.

The sequence:

transaction -> income or disposition -> capital or business -> Canadian-dollar value -> correct basis -> records.

Scope and date. This is Bitcoin tax in Canada at the federal level: Canadian federal income tax and Goods and Services Tax / Harmonized Sales Tax (GST/HST) for a taxpayer resident in Canada, flagging where the answer turns on entity type. Provincial tax, Quebec's separate regimes and non-residents (beyond section 6) are out of scope. CRA guidance re-checked 29 August 2026. Research, not tax advice.

Everything below assumes the bookkeeping itself is already settled. Our crypto accounting guide covers the wider workflow, Bitcoin accounting reconciliation covers the close, and our crypto tax accounting guide covers the other jurisdictions. Bitcoin tax in Canada asks a narrower question than any of them: which character, which amount, which record.

1. Capital property or business activity?

CRA does not settle this with a bright line: disposing of a crypto-asset may produce business income or loss, or a capital gain or loss, on the facts. CRA For the general test CRA points to paragraphs 9 to 13 of the archived Interpretation Bulletin IT-479R, Transactions in Securities, while warning that this does not make crypto-assets securities for tax purposes. CRA

CRA lists six factors that may indicate a business. CRA

• Frequency: extensive buying and selling
• Period of ownership: held briefly, turned over quickly
• Knowledge: experience in crypto-asset markets
• Time spent: substantial time studying them
• Financing: purchases financed by debt
• Advertising: advertising a willingness to buy

Frequency alone is not decisive, and nor is any other single factor: CRA decides case by case on all of them, and even an isolated transaction can be business income where it is an adventure or concern in the nature of trade. CRA No trade-count threshold or holding-period safe harbour exists.

Character changes the arithmetic, not the label. A capital-account holder computes proceeds less adjusted cost base (ACB) less outlays and expenses, then includes half the gain in income. CRA A business reports full profit through opening inventory, purchases, closing inventory and expenses, and values year-end holdings by one of CRA's two general inventory methods (lower of cost and year-end fair market value item by item, or the whole inventory at year-end fair market value) applied consistently, not by the capital-account averaging rule. Check the carve-out before choosing either. CRA's own valuation page adds that "property described in the inventory of a business that is an adventure or concern in the nature of trade must be valued at the cost for which you acquired the property", and an adventure or concern in the nature of trade is precisely how a one-off or speculative crypto venture is often characterised, so for those businesses the two-method choice is not available at all. CRA also treats each type of crypto-asset as a separate asset to be valued separately. CRA valuation

2. Bitcoin tax in Canada: treatment by transaction

"Not identified" means no event-specific CRA answer in the reviewed sources, not tax-free.

The own-wallet transfer row stops accountants inventing tax events: CRA states that some transactions do not result in a taxable disposition, "such as transfer of crypto-assets between wallets that you own." CRA It matters because a Bitcoin wallet holds no balance, only unspent transaction outputs (UTXOs): every spend consumes whole outputs and creates new ones, including change back to the sender. Rearranging outputs changes the on-chain picture, not who owns the coins.

3. Adjusted cost base: Bitcoin UTXOs are not Canadian tax lots

Buying BTC with Canadian dollars is an acquisition, and the amount paid plus the expenses of acquiring it enters a pooled ACB. CRA CRA describes that base as "usually the weighted average cost of a crypto-asset." CRA Behind the phrase sits the identical-property rule: buy and sell identical properties at different prices over time and you must calculate the average cost of the group at the time of each purchase, while dispositions do not change the ACB per unit. identical property

Bitcoin units are the same as one another, so on capital account they pool, and CRA states the averaging as a requirement, not an election: there is no specific-identification choice and no tax lot to select. identical property The cost basis methods a book subledger may run are not tax elections here.

Worked example: one pool, four events

An individual on capital account, ignoring fees. January: buys 0.50 BTC for CAD 30,000. March: buys 0.25 BTC for CAD 20,000.

Total quantity     0.75 BTC
Total pooled ACB   CAD 50,000
Average ACB        50,000 / 0.75 = CAD 66,666.67 per BTC

May: moves all BTC to a hardware wallet. Ownership does not change, so this is not a disposition and does not reset the ACB, though any network fee needs its own analysis (section 9). CRA

July: spends 0.10 BTC valued at CAD 9,000.

Allocated ACB      0.10 x 66,666.67 = CAD 6,666.67
Capital gain       9,000 - 6,666.67 = CAD 2,333.33
Pool after         0.65 BTC, approximately CAD 43,333.33 ACB

October: exchanges 0.15 BTC for ETH, the BTC being worth CAD 15,000.

Allocated ACB      0.15 x 66,666.67 = CAD 10,000
Capital gain       15,000 - 10,000  = CAD 5,000
Pool after         0.50 BTC, approximately CAD 33,333.33 ACB

Both gains are illustrative and before outlays and expenses; only half of each enters income as a taxable capital gain. CRA The average cost per BTC never moves on a disposal, and the Bitcoin outputs consumed in July and October played no part in either allocation.

4. Selling Bitcoin for Canadian dollars and computing the gain

A sale is a disposition. On capital account:

proceeds of disposition
  - adjusted cost base allocated to the BTC disposed of
  - outlays and expenses incurred to make the disposition
  = capital gain or loss

Where proceeds exceed the ACB and those outlays and expenses, a capital gain arises and must be reported. CRA Half then enters income as a taxable capital gain; half of a loss is an allowable capital loss usable only against taxable capital gains, never against employment income, and unused net capital losses carry back three years or forward indefinitely. Check the superficial-loss rule before claiming any of it. A loss is denied where you or an affiliated person buys the same or identical property in the period starting 30 days before the sale and ending 30 days after it, and still holds it 30 days after the sale; the denied loss is added to the adjusted cost base of the repurchased units instead. Crypto is where this bites hardest, because rebuying within a month is routine (CRA T4037). CRA

That half is the statutory inclusion rate, fixed for each taxation year: CRA's Capital Gains guide states an inclusion rate of 50% for 2025. CRA T4037 Confirm it for the year you are filing, because the figure has been the subject of announced changes and a wrong rate is a wrong tax bill.

Capital dispositions go in the "Bonds, debentures, promissory notes, crypto-assets, and other similar properties" section of Schedule 3; a business disposition runs through business income. CRA CRA Either way the amount is measured in Canadian dollars by a reasonable method applied consistently, with a record of how it was calculated. CRA valuation

5. Swaps, spending and barter receipts

A crypto-to-crypto trade is not tax-neutral because no fiat moved. CRA treats exchanging one crypto-asset for another as a disposition and works the example: units given up are disposed of at fair market value on the day, and the gain is that value less their ACB. CRA Properties are identical only where each is the same as all the others, so ether pools separately from bitcoin. identical property

Spending works the same way: CRA is explicit that paying for goods or services in cryptocurrency is barter, and that the payer is generally considered to have disposed of the cryptocurrency. CRA Buy a laptop for 0.02 BTC carrying an allocated ACB of CAD 1,200, at a transaction value of CAD 1,800, and the Bitcoin leg holds a CAD 600 gain before outlays and expenses.

Receiving BTC mirrors that. A vendor includes in income the value of the goods or services provided, or of the cryptocurrency accepted, whichever is more readily valued. That is an operative test, because the answer is not automatically the crypto side. CRA The BTC then carries its own cost, so selling it later is a second event. Skip the basis step at receipt and the later calculation cannot be supported. CRA

6. Mining Bitcoin in Canada

CRA's mining position is fact-dependent with a strong default: "In most cases, mining activities will be considered as carrying on a business due to the scale and resources involved." CRA mining Where that holds, the value of the crypto-assets received must be included in business income at the time it is earned. CRA mining Carry the condition: CRA states that inclusion for a person in the business of mining, so a non-commercial miner needs the business-or-hobby analysis first.

CRA identifies the two payments a successful miner receives (newly created crypto-assets and the block's transaction fees) but not how mined BTC is classified after receipt. CRA mining On the cost side, CRA considers that application-specific integrated circuit (ASIC) miners and graphics processing unit rigs used in a mining business can meet the conditions for capital cost allowance class 50, so hardware is depreciated, not expensed. CRA mining Costs incurred for the sole purpose of earning business income can be deductible, subject to the limits and capital rules. CRA business expenses

Residence matters: a non-resident using mining equipment located in Canada may be carrying on business here, may have to file a Canadian return, and may have a permanent establishment under an applicable treaty. CRA mining

Pool timing is the open question: CRA's page does not resolve share accruals, pay-per-share (PPS) or full-pay-per-share (FPPS) formulas, payout thresholds and retained fees into one recognition rule, so "BTC arrived in the wallet" is a fact, not an income analysis. Our Bitcoin mining accounting guide works those pool contracts through in detail.

7. Compensation paid in Bitcoin

The reviewed CRA crypto pages give no Bitcoin-specific payroll or withholding rule comparable to the US and UK guidance. That is a gap, not an exemption: ordinary employment, payroll and business-income rules apply, and the transaction still needs a Canadian-dollar value meeting CRA's valuation and records standards. CRA valuation CRA

Expect two consequences from one payment: the compensation deduction and reporting on one side, and a disposition of the BTC used to settle the obligation on the other. CRA Where guidance stops, state the boundary and apply the general law.

8. Gifts and donations

A gift of capital property is a deemed sale: "If you give capital property as a gift, you are considered to have sold it at its FMV at the time you give the gift," FMV being fair market value. The main exception is a transfer to a spouse or common-law partner, which rolls over at adjusted cost base under subsection 73(1) so no gain arises on the transfer, unless the transferor elects in that year's return not to have subsection 73(1) apply, in which case proceeds are deemed to be fair market value. Where the rollover applies, the attribution rules generally bring a later gain back to the transferor, so the gift defers the tax rather than moving it. CRA T4037 The recipient generally acquires it at fair market value on the date received, which becomes their ACB. identical property

Donating to a registered charity or other qualified donee is more intricate than "send BTC and deduct the wallet value." The donor is considered to have disposed of the property for proceeds equal to fair market value; but where that value exceeds ACB the donor may designate lower proceeds (no more than fair market value, no less than the greater of the ACB and any advantage in respect of the gift) and that amount also fixes the eligible amount of the gift for the credit. CRA P113

One trap for advisers who know the listed-securities planning move: the zero inclusion rate on donated capital property applies to a defined list (listed shares and debt obligations, mutual fund units and ecologically sensitive land among them) and crypto-assets do not appear on it. CRA T4037 That reading is our interpretation, not a CRA statement, so assume a taxable disposition plus a donation credit.

9. Bitcoin fees

The general shape is established: ACB is usually cost plus any expenses of acquiring the property, and a capital gain is net of the outlays and expenses incurred to make the disposition. identical property CRA An acquisition fee generally enters basis; a disposal fee reduces the gain.

The Bitcoin-specific case is not. The reviewed CRA transaction page gives no rule for a network fee, which matters because it is paid in BTC rather than dollars: whether paying it is itself a disposition of the BTC consumed is unanswered. Until it is, the ledger should carry evidence, not a conclusion:

• the BTC fee quantity and its Canadian-dollar value at the time;
• the transaction's purpose;
• whether the fee relates to an acquisition, a disposition or an internal transfer; and
• the policy applied to it, and why.

A fee absorbed silently into a wallet difference is a reconciliation break with tax attached.

10. GST/HST: a separate question with a separate answer

Income tax and GST/HST ask different questions; an answer under one does not carry across. Bitcoin is generally accepted as a virtual payment instrument, defined in subsection 123(1) of the Excise Tax Act as property that is a digital representation of value, functions as a medium of exchange and exists only at a digital address of a publicly distributed ledger, subject to exclusions. CRA Notice 324 CRA names bitcoin and ether as examples. CRA

Two consequences follow, easily confused. Where a GST/HST registrant accepts BTC for taxable property or services, the GST/HST on that supply is calculated on the fair market value of the crypto-asset at the time of the transaction. The goods are not exempt because they were paid for in Bitcoin. CRA Separately, the sale of a crypto-asset meeting the definition is an exempt supply of a financial service, so no GST/HST applies and no input tax credits (ITCs) may be claimed on it. CRA

Mining: section 188.2 of the Excise Tax Act

Section 188.2 was enacted by the Budget Implementation Act, 2023, which received Royal Assent on 22 June 2023, and is deemed to have come into force on 5 February 2022. CRA Notice 324 Subject to one exclusion, subsection 188.2(4) deems the provision of a mining activity not to be a supply, so the miner charges no GST/HST on a mining payment; subsection 188.2(2) deems property and services acquired for mining activities to be acquired otherwise than in commercial activities, so no ITCs are available, even where the miner earns no reward. CRA Notice 324 CRA summarises this as a miner being considered not to be engaged in commercial activity for GST/HST purposes. CRA

Two qualifications travel with that rule and are routinely dropped. The deeming does not change the income tax answer: the same person "may still be considered to be carrying on a business for income tax purposes." CRA And subsection 188.2(5) switches the rule off where the mining activity is performed for another person whose identity is known to the supplier, subject to conditions on mining-group operators and non-arm's-length non-residents; general GST/HST rules then apply. That reversal matters commercially: the participant is making an ordinary taxable supply of computing resources, so input tax credits on electricity and hardware come back into play and registration and collection have to be considered. CRA Notice 324

A mining pool is also not automatically a "mining group" for section 188.2: CRA's June 2025 update to Notice 324 indicates that a participant paid on the expected value of blocks, regardless of the pool's actual result, may not be sharing in mining payments. CRA Notice 324

11. Records CRA expects

Bitcoin tax in Canada is only as good as the file behind it. CRA requires adequate books and records for each crypto-asset transaction, expressly for individuals and businesses alike, asking for the following plus the associated accounting, legal and software receipts. CRA

• the number of units and type of crypto-asset;
• the date and time;
• its value in Canadian dollars at that time;
• the nature of the transaction and the other party, even if only their address;
• the addresses associated with each digital wallet used; and
• the beginning wallet balance and its cost, and the ending balance, for each crypto-asset each year.

Exchange users also need trade and transfer ledgers; miners need hardware receipts, expense records covering power and pool fees, and pool agreements with exported activity. CRA Retention is at least six years from the end of the last taxation year to which the records relate, and CRA advises exporting exchange history regularly. CRA

A block explorer link is not a tax file: it proves an output moved, nothing about who owned it or its value.

12. Where Canadian Bitcoin guidance is still incomplete

Bitcoin tax in Canada is not fully mapped. Several recurring events have no event-specific CRA answer in the reviewed sources:

• mining-pool accrual timing;
• Bitcoin lending, borrowing and collateral liquidation;
• Lightning channel mechanics;
• lost private keys and deliberate sends to unspendable outputs; and
• network-fee fact patterns generally.

Client-facing reporting is the live watch item. Finance Canada's August 2025 draft legislative proposals would add a new Part XXI, Crypto-Asset Reporting Framework (CARF), to the Income Tax Act, applying to the 2026 and subsequent calendar years. Finance draft But the consolidated Act, current to 21 June 2026, still ends at Part XX, and has no Part XXI. Income Tax Act Draft is not law: confirm enactment and commencement before telling a client that exchange reporting has begun.

A gap is not an exemption: apply the general law to the facts, document the position, and take advice where the amount is material.

Practical takeaway

Bitcoin tax in Canada rewards one habit above all others. Classify first, then compute: character decides which arithmetic applies, the Canadian-dollar value decides the amount, and the records decide whether either survives. For a capital-account holder the lesson is shorter:

Canadian Bitcoin ACB is a pooled tax history across identical property. It is not the set of UTXOs the wallet happened to select.
