CARF is the OECD's Crypto-Asset Reporting Framework, and Canada has legislated it in draft with an application date of January 1, 2027. Budget 2025's tax measures list it as “subject to a deferred application date of January 1, 2027,” and Finance Canada put the implementing rules into Bill C-31 on May 7, 2026. Under the draft, crypto platforms will report their users' details and transactions to the CRA. You do not file anything yourself, and nothing changes in how you report your own gains, but the CRA will have far more data to compare your return against.
- Start: January 1, 2027, per Budget 2025 (deferred from the draft's 2026)
- Who reports: crypto-asset service providers carrying on business in Canada, not you
- Reported: your name, address, tax residence, tax ID number, date of birth, plus transaction amounts and types
- Status: in Bill C-31, introduced May 7, 2026; check Parliament for the current stage
Everyone asks whether this means the CRA will see everything. It means platforms will report, on a standard international template, what you did on them. If you already report accurately, CARF is mostly a reason to tidy your records. If you have been vague about swaps or small gains, it is a reason to stop. Every date on this page comes from a Government of Canada source or is flagged as my reading of one.

What Is CARF And Why Is Canada Adopting It?
CARF provides for the automatic exchange of tax information on crypto-assets between countries. The OECD built it so tax authorities can see crypto data in the way they already see bank-account data under the Common Reporting Standard. Finance Canada said in November 2023 that it would work to put CARF into domestic law and activate exchange agreements in time for exchanges to begin by 2027. A standard template also helps platforms that serve people in several countries, because they do not file in a different format for each government.
Who Has To Report Under CARF In Canada?
The draft legislation applies to reporting crypto-asset service providers: entities or individuals who provide services that facilitate exchange transactions for customers, including as a counterparty, an intermediary or a trading platform operator. A provider is covered if it is resident in Canada, organized under Canadian law with tax filing obligations, managed from Canada, or carries on business in Canada. So exchanges and brokers are in scope. You, as a customer, are the person being reported on. You do not file a CARF return.
What Information Will Platforms Report About You?
| Category | Details |
|---|---|
| Reportable user (individual) | Name, address, jurisdiction of residence, tax identification number and date of birth |
| Entity users | Entity details, plus the identity and role of reportable controlling persons |
| Transactions | Amounts, number of units and type of transaction, covering acquisitions, dispositions and transfers |
| Assets covered | “Relevant crypto-assets”: digital representations relying on cryptographically secured distributed ledgers, excluding central bank digital currencies and specified electronic money products |
| Penalty example | $500 for each failure to provide a requested tax identification number, with exceptions where an application was made within 90 days or the jurisdiction issues no numbers |

Two things stand out. First, transfers are reported, not only sales, so moving coins matters. Second, existing users are not exempt: the draft requires providers to finish due diligence on pre-existing users before 2027, which is why your platform may ask for your tax residence and a tax ID number around now.
When Does CARF Start In Canada?
The August 2025 draft proposed that the first reporting period would be calendar year 2026. Budget 2025 then deferred the application date to January 1, 2027, and that is the date to plan around. The draft's rule is that the information return is filed before May 2 of each calendar year for the preceding year. Put together, that points to the first reports covering 2027 being filed before May 2, 2028. That last step is my reading of the two documents, not a date the government has published as a single sentence. Bill C-31 must pass before any of it is law, so check Parliament's LEGISinfo page for its stage.
What Does CARF Mean For Your Crypto Taxes?
The CRA's rules for you do not change. It treats crypto as a commodity; income from it is either business income or a capital gain depending on the circumstances. A disposition can occur when you trade crypto for currency or for another crypto-asset, or use it to buy goods and services. Moving crypto between wallets you own is not a disposition. What changes is visibility.
- Keep complete records now. The CRA says to record units, dates and times, the Canadian dollar value at the time, and your wallet addresses, and to keep records at least six years.
- Reconcile your own numbers with each platform's year-end summary. The gap between the two is what a data match would surface.
- Report crypto-to-crypto swaps, not only sales to CAD. CARF covers acquisitions, dispositions and transfers.
- Answer your platform's requests for tax residence and a tax ID number. Platforms are required to collect them.
- If you are unsure how to report, use my filing guide and ask an accountant.
Does CARF Replace FINTRAC Reporting?
No. FINTRAC reporting is anti-money-laundering: a registered money services business reports virtual currency receipts of $10,000 or more, and verifies identity at $1,000. CARF is tax reporting, made to the CRA. They run side by side. Read my FINTRAC guide for the first and my tax guide for the second. The foreign-property form is separate again; see T1135 and crypto.
Which Platforms Will Be In Scope?
Any platform with a Canadian connection that facilitates crypto exchanges for customers. In my ranking that includes Canadian-registered platforms such as Coinbase, Kraken, Wealthsimple Crypto and Newton, which already collect identity data under FINTRAC rules. It may also reach offshore platforms that carry on business in Canada, though how that works in practice is not something I can verify. If an exchange tells you it collects no identity details, that is a regulatory red flag, not a feature. Compare how they handle compliance on my exchange ranking.
Is Your Platform Already Asking For Your Tax Details?
Possibly. Because the draft requires providers to complete due diligence on pre-existing users before 2027, many platforms are already refreshing profiles: tax residence, a tax identification number, and sometimes proof of address. Treat these requests as routine, not as a sign that something is wrong with your account. Answer accurately. The draft penalty example is $500 for each failure to provide a requested tax identification number, and the compliance duty sits with the platform, which is why it asks. Check your exchange's notices and your registered email, and keep a copy of whatever you submit.
What Changed For CARF In Canada In October 2026?
- Finance Canada introduced Bill C-31, the Budget 2025 Implementation Act, No. 2, which implements the Crypto-Asset Reporting Framework.
- Finance Canada released draft Income Tax Act legislation for CARF and the Common Reporting Standard for consultation.
- Finance Canada committed to transposing CARF into domestic law so exchanges can begin by 2027.
