Facing a CRA Crypto Tax Audit: How Canadian Investors Can Prepare
A CRA information request arrives regarding multiple tax years. The investor reviews their exchange accounts to view historical activity and finds the issue quickly: One platform has been closed for two (2) years. Another platform has new ownership. And none of the transactions that have been transferred between their personal wallets are tracked.
This situation happens more than people think. In Canada, around 10% of the population owns bitcoin. As such, most investors treat it as an investment opportunity instead of a payment option. Therefore, investments are spread across multiple platforms and self-custodied wallets, making it difficult to track and log the various transactions. When the CRA sends letters to inquire about these investments, finding and organizing this history is the first hurdle.
Organize History Effectively
Reading the CRA letter carefully prior to beginning is a great way to save time. Confirm that the CRA letter is legitimate. The CRA provides documentation on how to verify communications with taxpayers. Confirm that the CRA letter matches the CRA documentation. Identify which tax years and accounts/activities are being reviewed. Are they looking for dispositions, mining/staking income, etc.? This determines which records to gather.
Identify the response date and if there is a firm due date. If there is too much time to assemble all of the necessary records from the multiple platforms being utilized, send a written request for an extension prior to the due date. Sending an extension request after the due date has passed is likely more unproductive than sending an incomplete response.
Also important to note is that some letters are informational, while others are assessments or claims. Understanding the type of correspondence will help ensure you respond appropriately. Using language directly from the letter will ensure that you address exactly what the CRA is asking for, rather than assuming what they want.
Another factor to consider is that the Crypto Asset Reporting Framework will require expanded reporting and data sharing from crypto-platforms going forward. As a result, third party information about account activity will become readily available to the CRA. The quality of your records gathered proactively will become even more important moving forward.
Document Checklist
- Transaction history downloads from every exchange used
- Public addresses and transaction IDs for self-custody holding wallets
- Bank statements and payment records related to fiat movement
- Trading fees, network fees and platform withdrawal fees
- Valuation of cryptocurrencies using Canadian dollars including conversion basis
- Summary statements and tax receipts received from exchanges
- Returns submitted for each tax year under review
- CRA correspondence maintained in a single location
Build a Complete Record of Your Crypto Activity
Collecting cryptocurrency tax records is usually the most time-consuming part of responding to a CRA crypto tax audit, and it is worth doing methodically rather than in a rush.
Exchange exports form the foundation. Most platforms allow a transaction history download covering a full account lifetime, and pulling that complete file is more useful than a year-by-year approach that risks gaps at the boundaries. Where the platform offers a full account statement rather than a filtered report, take the full version.
Wallet records are the second layer. For self-custodied holdings, the public addresses involved and the transaction IDs for significant movements provide a way to demonstrate what happened on chain. Someone who has used multiple wallets over several years will need to identify which addresses belong to them, which is easier to establish from contemporaneous notes than from memory.
Bank and payment records connect the crypto side of the activity to the Canadian financial system. Fiat deposits, withdrawals and e-transfers that funded purchases or received proceeds are part of the chain of evidence, and they often resolve the question of what a particular crypto transaction cost in Canadian dollars.
Fees deserve their own attention because they affect the adjusted cost base and the proceeds of disposition calculations. Trading fees, network fees and platform withdrawal charges are all relevant, and they are easy to overlook when working from a summary rather than a detailed export.
Canadian-dollar valuations are the piece that ties the record to the return. Each disposition needs a fair market value in Canadian dollars at the time it occurred, and each acquisition needs a cost in the same terms. Where a platform reported values in another currency, the conversion basis should be documented so the source of the figure is traceable.
Two cautions apply throughout. First, records should never be created or altered after the fact to fill a gap. Second, completeness matters more than presentation at this stage; organising comes after gathering.
Reconcile Transactions Before Drawing Conclusions
Raw transaction histories rarely reconcile on their own. Before any conclusions are drawn about what was owed, the data usually needs cleaning, and this is where reassurance sometimes appears.
Transfers between your own wallets are a frequent source of apparent discrepancies. Moving assets from an exchange to a hardware wallet, or between two wallets you control, does not normally create a disposition, but it will appear in export files as an outgoing and an incoming transaction. Untreated, those movements can inflate transaction counts dramatically and create the impression of far more disposal activity than actually occurred. Pairing them up removes that distortion.
Duplicate imports are another common problem. Where a portfolio tracker pulls data from multiple exchanges and also receives manual entries, the same transaction can appear twice. Filtering those out before calculating anything prevents a double count that would distort both the adjusted cost base and the reported gain.
Missing acquisition records are the hardest to resolve. Where coins were purchased years ago on a platform that no longer retains history, the cost basis may need to be reconstructed from bank records, email confirmations or other supporting evidence. Documenting how the figure was arrived at, and flagging it as an estimate where that is honest, is better than presenting a guess as a certainty.
Differences between exchange summaries and tax calculations are worth understanding rather than assuming an error. Exchanges report activity, not necessarily tax treatment. A summary may show total proceeds without distinguishing capital from income, may exclude certain fee types, or may value transactions in a currency other than Canadian dollars. Reconciling the two views, and being able to explain any remaining difference, is part of preparing a defensible position.
Explain the Tax Treatment Behind Your Return
When preparing a crypto tax audit, the key to organizing a large amount of data into a coherent and defendable package is a clear, organized approach.
A simple list (or table) of all items listed in the order they were received will serve as the best organizational structure. The list should refer to the corresponding document, with a quick description of what that document includes and how it helps answer the corresponding question posed. File names should clearly reflect content so they don’t need to be opened to understand; e.g., “2020 Exchange Statement” or “Bank Transfer Record”.
Document Assumptions Clearly
Don’t leave assumptions hidden. When you’ve had to reconstruct a cost basis, convert a foreign currency to CAD, or find a lost wallet address from incomplete records, provide a small paragraph of text that describes how you got the number.
Separate Documented Facts from Reasoned Estimates
In addition to keeping documents transparent and honest regarding the nature of information included within them, separating documented facts from reasoned estimates provides credibility when responding to questions about figures that did not seem to come out of thin air.
Identify Gaps Instead of Concealing Them
If you’re unable to obtain a history from a third-party platform, say so and explain what alternatives you tried to get the missing portion of history. A response that identifies what you don’t know appears more believable than one that presents itself as perfect but lacks proof.
Record All Communications and Keep Copies of Everything Submitted
Track communications via date, party(s), subject matter, etc. This creates a paper trail if the file extends over many months. Follow submission methods specified by the CRA. Use safe channels wherever possible.
Obtain Professional Help for Complex Cases
Using outside professional help is perfectly acceptable for difficult cases, especially complex multi-year histories, mixtures of personal and business use, or disagreements with the CRA about the calculation. Faris CPA’s crypto tax audit support service illustrates how professional help can be delivered in this way. Ask potential advisors what services they offer (scope), what records they require access to, who retains responsibility for accuracy, and what are their fees? Situations involving an objective review of complex multi-year histories, blended personal/business uses or ongoing disagreement over calculations are ideal candidates for a second opinion.
Disputes Regarding Reassessments
A CRA reassessment is not necessarily final. Where a CRA-assigned reassessment affects your belief of correctness regarding the assessed amount, established procedures exist for contesting it and vary according to the category of assessment.
For some categories deadlines vary. Check the CRA’s published materials or the notice itself instead of guessing. For some types of assessments (e.g. Income Tax) deadlines begin from the issuance date of the notice while others (GST/HST or Payroll) operate under entirely separate timing regimes. To avoid confusion, never cite a single deadline as applying universally to all scenarios.
A well-supported dispute is often based upon identical evidence supporting the initial return preparation — i.e. original transaction records, your reconciliation, and the rationale behind the original tax treatment applied. Since documentation compiled during an audit process is carried forward here too, organize it accordingly right from the start.
Maintain Relatively Simple Routine Now
Your simplest defense against a difficult audit down the road is maintaining a relatively simple routine now.
As recommended by the CRA, regular exports of transaction records rather than expecting exchanges to keep them forever reduces your reliance on them. Further still, exchanges have different policies with respect to retaining historical data. Regularly exported and stored by yourself in an environment you have complete control over ensures this information remains accessible even if an exchange closes its doors, withdraws from Canada or limits your ability to access your account.
Regular reconciliations make it much simpler to track your activity. Eliminating duplicate transactions and updating cost bases quarterly or annually is significantly easier than attempting to construct a five-year timeline after-the-fact. Having readily available fiat records related to each crypto record allows you to immediately determine the CDN dollar equivalent of every transaction.
Typically, taxpayers are required to retain records supporting their return filings for a minimum of six years from the close of the last tax year to which they pertain; and potentially longer in other circumstances. Organizing your electronic files in a consistent format per year facilitates retrieval and response to any subsequent requests for information.
FAQS
What records do I need to gather for a CRA crypto audit?
You’ll want to collect a complete export of all your transaction history from each exchange you’ve utilized; wallet addresses and associated transaction identifiers for any self-custody holdings; bank transfer records demonstrating CDN dollars movement; records detailing any fees charged; and CDN dollars valuation of each transaction. In addition, include the returns as originally filed; any exchange tax receipts; and all communication with CRA in one organized binder.
What if an exchange closes before I can retrieve my transaction history?
Attempt to reconstruct as much as you can from other sources (i.e.: bank statements; emails confirming transactions; credit card statements; screen captures and/or previous export files). If you cannot establish with certainty the cost of acquiring something, describe in detail how you arrived at that number and label it as an estimation. It’s preferable to explain why there is no information in lieu of leaving it blank.
Do trades between my wallets constitute taxable events?
Generally speaking, yes. However, merely transferring an asset between wallets that you personally control typically constitutes an event where you haven’t transferred ownership. Thus, both wallets may report these transfers as paired outgoing/incoming transactions in their respective export files; therefore, they should be matched up and eliminated from disposition calculations to prevent misrepresenting activity levels.
What can I do if I disagree with CRA’s calculations?
CRA offers formal mechanisms for disputing assessments, starting with submitting an Objection Against Assessment. The applicable deadline varies based on the type of assessment and/or notice issued; therefore, verify the relevant due date as opposed to assuming it. A strong objection is typically supported by your original transaction records, your reconciliation, and the rationale behind the tax treatment initially selected.
