Overview — Cryptocurrency Mining and Canadian Income Tax
Cryptocurrencies such as Bitcoin or Ethereum are digital assets that use cryptographic techniques to verify the transfer of assets and control the creation of new units of the currency. Their ledger — the blockchain — is not controlled by any central authority. Instead, independent parties known as cryptocurrency miners validate transactions and are rewarded with newly created units of the cryptocurrency for doing so.
This is just one of several ways cryptocurrency is taxed in Canada, and as cryptocurrency valuations continue to draw new participants into mining, and as the Canada Revenue Agency’s ability to detect unreported crypto income expands under the incoming Crypto-Asset Reporting Framework, it is more important than ever for Canadian miners to understand the income tax and GST/HST consequences of their mining activity.
Background — CRA’s Administrative Position on Crypto Mining
The CRA has never enacted a standalone “crypto mining tax” — mining income is taxed under the same general provisions of the Income Tax Act that apply to any other business or hobby activity, informed by decades of case law on the business-versus-hobby distinction. The CRA has, however, published guidance specific to mining. Its March 2023 tax tip on mining cryptocurrency confirms that mining activities have tax implications and that the treatment turns on the facts of each miner’s operation.
On the GST/HST side, section 188.2 of the Excise Tax Act — enacted through the Budget Implementation Act, 2023 — generally deems mining activities not to be a “supply” for GST/HST purposes, a position the CRA has detailed in GST/HST Notice 324, Mining Activities in respect of Cryptoassets (most recently revised June 2025). This means most solo miners cannot register for GST/HST or claim input tax credits on their mining equipment and electricity costs, since there is generally no identifiable recipient of a taxable supply.
Layered on top of this is the incoming Crypto-Asset Reporting Framework (CARF), implemented in Canada through Bill C-31. Reporting obligations apply to the 2027 and subsequent calendar years, with the first platform-level filings due before May 2, 2028. Once in force, Canadian crypto-asset service providers will be required to report user transaction data to the CRA, which will exchange it with over 50 partner jurisdictions internationally. For miners who dispose of mined coins through Canadian or foreign exchanges, this materially narrows the practical anonymity that has historically made crypto mining income difficult for the CRA to detect.
CARF reporting timeline: 2026 due diligence begins, 2027 reporting years start, first filings due before May 2, 2028.
Key Issues and Findings
Business or Hobby: The Determinative Question
The tax treatment of mining for a particular individual still depends on the facts and circumstances of that individual’s operation. The courts have held that for an activity to be a business, the taxpayer’s predominant intention must be to make a profit, carried out in accordance with objectively businesslike standards of conduct. Where personal elements outweigh the commercial elements, the activity remains a hobby.
There is no fixed list of factors, but courts and the CRA typically consider:
- Profits and losses from the activity in prior years;
- The taxpayer’s relevant training (in computer programming, blockchain technology, or hardware);
- The taxpayer’s intended course of action and business plan;
- The capability of the activity to show a profit;
- The presence of conventional business financing, such as loans; and
- The scale of equipment and operation (a single home rig versus a dedicated mining facility).
Miners with formal training, borrowed capital, and a documented profit motive are far more likely to be treated as running a business than a hobbyist mining on a personal computer — the same business-versus-capital distinction that applies to trading cryptocurrency and other securities more generally.
The CRA’s own 2023 mining tax tip frames this same inquiry using its traditional adventure-in-the-nature-of-trade factors: the frequency of transactions, the period the taxpayer holds the mined coins, the taxpayer’s knowledge of cryptocurrency markets, the time devoted to the activity, the use of financing, and the taxpayer’s profit motive.
These CRA-specific factors and the court-derived list above are two lenses on the same underlying test, not competing rules, and the CRA has indicated that most organized, substantial mining operations will default to business treatment unless the facts clearly show a personal, non-commercial activity.
Business versus hobby crypto mining tax treatment comparison.
Tax Consequences If Mining Is a Business
Where mining constitutes a business, there are two possible treatments for the coins a miner receives. Under one approach, the fair market value of the mined coins is included in income at the time they are received — the mining activity itself is treated as generating business income, in the same way a service business recognizes income as it is earned.
Under the other approach, the coins are treated as inventory: no income inclusion arises on receipt, and income (or loss) instead crystallizes only when the coins are later disposed of, with the coins valued under the Income Tax Act’s inventory rules in the meantime. Which treatment applies depends on the specific facts of the mining operation, and this is an area where professional guidance is genuinely necessary rather than a settled default. In either case, business income is fully includible, in contrast to a capital gain, only 50% of which is taxable.
Commercial miners can deduct business expenses — equipment, electricity, rent, and loan interest — though where coins are held as inventory, expenses embedded in the cost of that inventory can generally only be deducted in the year the coins are sold, not the year they are mined. Business mining income and expenses are reported on Form T2125, Statement of Business or Professional Activities, filed alongside your T1 personal return (or on the applicable corporate schedule if you mine through a corporation) — as distinct from the Schedule 3 filing used for hobby mining gains.
Where coins are held as inventory, the Income Tax Act’s valuation rules require a consistent method applied year over year: a miner can value inventory at its cost, or at the lower of cost and fair market value at year-end, item by item or as a whole pool. Choosing the lower-of-cost-and-fair-market-value method is what allows a write-down deduction when year-end prices fall below cost; the straight-cost method does not. In some circumstances, a commercial miner may be able to segregate a portion of mined coins into a genuine long-term holding, supporting a change in use from inventory to capital property and converting future gains into capital gains.
Tax Consequences If Mining Is a Hobby
A hobbyist miner similarly has no income inclusion on receipt of mined coins, but the coins are treated as capital property rather than inventory. Disposition then produces a capital gain or loss, only half of which is taxable — a significant advantage given that the 50% capital gains inclusion rate remains in place (the previously proposed increase to 66.67% was cancelled and will not be reintroduced). The tradeoff is that hobbyist miners cannot deduct mining-related expenses as they’re incurred; instead, those costs are captured in the adjusted cost base used to calculate the eventual gain or loss.
There’s a genuine industry debate on what that adjusted cost base actually is: some commentators treat it as zero, on the theory that the miner paid nothing to “acquire” the coin. In our view, that’s the wrong analogy. A hobby miner is not receiving a gift or a windfall — they are incurring real costs (electricity, hardware wear, and time) to produce the coin, in exactly the same way a physical prospector who pans for gold incurs costs to extract it. The adjusted cost base should reflect that cost of production, not be treated as nil. This is a position worth discussing with a Toronto tax lawyer before filing, since it directly affects the size of the eventual capital gain, and the CRA has not settled the question definitively.
“Some say a hobby miner’s cost base is zero because nothing was paid for the coin. But a prospector who spends money and effort pulling gold out of the ground has a cost base in that gold — a crypto miner running the same calculation on electricity and hardware is no different.”

Hobby mining gains are reported on Schedule 3 (Capital Gains or Losses) with your T1 return, distinct from the T2125 filing used for business mining income discussed above.
GST/HST Treatment
Regardless of business or hobby characterization, GST/HST Notice 324 confirms that most mining activity — validating transactions, maintaining the ledger, or contributing computing power to a mining pool — is deemed not to be a taxable supply, because there is typically no identifiable recipient paying for the activity. An exception applies where a miner performs mining for a specific, identifiable person outside a qualifying “mining group” arrangement; in that narrower case, ordinary GST/HST rules can apply. Miners operating through pools should have their arrangements reviewed to confirm which side of this line they fall on.
Recent Case Law: Amicarelli v. The King, 2025 TCC 185
In December 2025, the Tax Court of Canada released its decision in Amicarelli v. The King, 2025 TCC 185 — the Court’s first judicial definition of Bitcoin and its first detailed treatment of losses arising from cryptocurrency theft or exchange collapse (the case arose from the QuadrigaCX collapse). While the case addresses loss characterization rather than mining specifically, it is the clearest signal yet that the Tax Court is prepared to apply conventional property and business-income principles to cryptocurrency with real analytical rigour, rather than treating crypto assets as a categorically novel problem. Miners holding coins long-term, or disposing of them through exchanges, should expect the same level of judicial scrutiny of their facts.

Staking Is Not Mining
Miners moving between proof-of-work and proof-of-stake activities should note that the CRA does not treat staking the same as mining. A January 2025 CRA interpretation (2024-1031821I7) confirmed that custodial staking rewards are taxable as income at fair market value at the moment they are credited to the taxpayer’s wallet — there is no equivalent “no income inclusion on receipt” treatment as there is for mined coins characterized as inventory or capital property. Taxpayers who both mine and stake need to track each activity separately.
Implications for Canadian Taxpayers
The combination of CRA’s 2023 mining guidance, GST/HST Notice 324, and the incoming CARF reporting regime means miners face materially higher scrutiny than when this article was first published in 2020.
Practically, this means: maintain contemporaneous records of mining equipment costs, electricity usage, pool arrangements, and the fair market value of coins on the date received; document your profit intention and business plan if you intend to claim business treatment and its associated deductions; and anticipate that CARF will make it substantially harder to under-report proceeds from coins mined and later sold through an exchange, once first filings begin ahead of the May 2, 2028 deadline.
Miners who have historically under-reported should consider whether a Voluntary Disclosures Program application is appropriate before that reporting window narrows further, and should understand what to expect if the CRA opens an audit into their mining activity.
Takeaway
Cryptocurrency mining remains taxable in Canada, and the fundamental business-versus-hobby analysis from the courts has not changed. What has changed since this article was first published is the volume of CRA guidance now available — GST/HST Notice 324, the 2023 mining tax tip, and the 2025 staking interpretation — and the arrival of a case, Amicarelli, in which the Tax Court engaged directly and rigorously with cryptocurrency facts. Combined with CARF’s international information exchange starting with 2027 transactions, miners have less room than ever to treat classification as an afterthought.
Pro Tax Tips
- Miners should resist the temptation to decide their tax characterization after the fact, once a large gain has already materialized; the courts and the CRA look at the taxpayer’s conduct and intention throughout the activity, not simply at the year of disposition.
- Individuals who have received significant unanticipated gains from coins that were arguably mined as a hobby should get a proper legal opinion before filing, since the CRA’s fact-driven test leaves genuine room for characterization disputes in either direction, and the tax consequences of getting it wrong — full inclusion as business income rather than a 50% capital gain, or vice versa — can be substantial.
- Commercial miners should keep meticulous records distinguishing coins held for genuine long-term investment from those held as inventory for resale, since a credible change-in-use argument can meaningfully reduce tax on coins eventually sold.
- Given that CARF will soon put exchange-level transaction data into the CRA’s hands, any miner with historical unreported income should address it proactively through the Voluntary Disclosures Program rather than waiting for a reassessment.
FAQs
Is cryptocurrency mining taxable in Canada?
Yes. Whether treated as business income or a personal hobby producing capital gains, mining income is taxable under the general provisions of the Income Tax Act — there is no separate exemption for mining.
How do I know if my mining activity is a business or a hobby for tax purposes?
The CRA and the courts look at your overall conduct: your training, whether you financed equipment with loans, whether you have a business plan, and whether the activity is capable of showing a profit. No single factor is decisive.
Do I pay tax when I receive newly mined coins, or only when I sell them?
It depends on your facts and which treatment applies. If mining is a hobby, the coins are capital property and there’s no income inclusion until you dispose of them. If mining is a business, there are two possible treatments: the fair market value of the coins may be included in income at the time you receive them, or the coins may be treated as inventory with the tax consequence deferred to disposition. This is a fact-specific question that warrants professional advice rather than a default assumption.
What’s the tax difference between mining as a business versus a hobby?
Business income from selling mined coins is 100% taxable and allows deduction of related expenses (though inventory-related costs are deductible only in the year of sale). Hobby mining produces capital gains, only 50% of which are taxable, but no expense deductions are available.
Does GST/HST apply to cryptocurrency mining?
Generally no. Under section 188.2 of the Excise Tax Act and GST/HST Notice 324, most mining activity is deemed not to be a taxable supply because there is typically no identifiable recipient. An exception can apply to mining performed for a specific identifiable party outside a qualifying mining-group arrangement.
Is staking taxed the same way as mining?
No. The CRA has confirmed that custodial staking rewards are taxable as income at fair market value when credited to your wallet — unlike mined coins, there is no deferral of income inclusion to the date of disposition.
What is the Crypto-Asset Reporting Framework (CARF) and how does it affect miners?
CARF is an international framework, implemented in Canada through Bill C-31, requiring crypto-asset service providers to report user transaction data to the CRA starting with the 2027 calendar year, with first filings due before May 2, 2028. Miners who dispose of mined coins through exchanges should expect this activity to become visible to the CRA through cross-border information exchange.
Can I deduct my mining equipment and electricity costs?
Only if your mining activity is characterized as a business. Hobbyist miners cannot deduct these costs, though they form part of the adjusted cost base used to calculate the eventual capital gain or loss.
What tax form do I use to report crypto mining income in Canada?
Business mining income and related expenses are reported on Form T2125, Statement of Business or Professional Activities, filed with your personal T1 return, or on the corresponding corporate schedule if you mine through a corporation. Hobby mining gains are reported on Schedule 3 (Capital Gains or Losses) instead.
How do I value my mined cryptocurrency inventory for tax purposes?
If you’re mining as a business, the Income Tax Act lets you value your coin inventory either at cost, or at the lower of cost and fair market value at year-end, applied consistently from year to year. The lower-of-cost-and-market method allows you to claim a write-down deduction when prices fall below your cost; the straight-cost method does not.
What happened in the Amicarelli case and does it apply to mining?
Amicarelli v. The King, 2025 TCC 185, is the Tax Court’s first detailed judicial treatment of Bitcoin, addressing losses from the QuadrigaCX collapse. It doesn’t deal with mining directly, but it signals that the Court is applying conventional tax principles to crypto assets with real scrutiny — relevant to any miner disposing of coins through an exchange.
What should I do if I haven’t reported past mining income?
Consider a Voluntary Disclosures Program application before CARF’s cross-border reporting begins. An experienced Canadian tax lawyer can assess whether your circumstances qualify for relief from penalties and prosecution.
Can commercial miners reduce their tax rate by incorporating?
Miners running a genuine business may access the small business deduction on active business income earned through a corporation, which can meaningfully lower the tax rate compared to mining as a sole proprietor.
What is my adjusted cost base if I mine cryptocurrency as a hobby?
There’s debate on this point — some commentators say the cost base is zero, since the miner didn’t pay to acquire the coin. In our view, that’s the wrong analogy: a hobby miner incurs real costs (electricity, hardware wear, time) to produce the coin, similar to a prospector extracting gold, and the adjusted cost base should reflect that cost of production rather than being treated as nil. This affects the size of your eventual capital gain and is worth discussing with a tax lawyer before you file, since the CRA hasn’t settled the question definitively.
When do I need to file and report my crypto mining income in Canada?
Crypto mining income and gains are reported as part of your annual tax return, due by April 30 for most individuals (June 15 for self-employed individuals and their spouses, though any balance owing is still due April 30). There’s no separate crypto-specific filing deadline.
Is there a minimum amount of mining income I need to report?
No. All mining income is reportable regardless of amount; there is no de minimis exemption under the Income Tax Act.
“The CRA’s guidance has caught up with mining, but the underlying test hasn’t changed — what’s changed is how much visibility the CRA will soon have into what miners actually do with the coins once they sell them.”
