Getting a letter from the CRA about your crypto taxes can feel alarming, especially when it includes dozens of detailed questions. With Canada tightening its grip on digital asset reporting, crypto users are increasingly being selected for audits.
Whether you are a trader, investor, or miner, the CRA expects full transparency. From the source of your funds to every transaction and wallet, they want a paper trail that proves you have paid what you owe. If you are unsure what questions might come your way or how to respond, you are not alone.
In this guide, we will break down the most common CRA audit questions and how to stay prepared, so you can approach the process confidently and avoid costly penalties.
Why is the CRA Auditing Crypto Investors?
The CRA has significantly increased its scrutiny of cryptocurrency activity in recent years. The shift is driven by a desire to catch underreported gains and understand the scale of crypto participation across the country. Several factors have triggered this enhanced focus, especially for those interacting with foreign platforms or high-volume transactions.
Coinsquare Case and Data Collection Powers
In 2021, the CRA won a court order to access user data from Coinsquare, one of Canada’s largest exchanges. This marked a pivotal moment in enforcement. Coinsquare had to share account information for thousands of users dating back to 2014. The decision empowered the CRA to build audit cases based on platform usage, trading volume, and unreported income.
Global Data Sharing with the IRS and Other Tax Authorities
Canada’s cooperation with international tax bodies like the IRS means crypto transaction data is increasingly shared across borders. If you used a US exchange like Coinbase, there is a chance the CRA already has access to your records. This cross-border collaboration has made it easier for the CRA to flag mismatches in foreign holdings.
Gaps in Early Reporting by Canadian Investors
In the early days of crypto, many Canadian investors did not report gains accurately or at all. The anonymous nature of wallets and decentralized exchanges led to a belief that crypto was invisible to regulators. The CRA is now going back several years to investigate gaps in disclosures and track the origins of undeclared assets.
Focus on High-Value and Frequent Transactions
High-volume trading, especially across multiple platforms, often attracts CRA attention. If your transactions are large or frequent, the CRA may suspect that you are operating as a business, not a casual investor. This triggers deeper audits to reassess whether your gains should be taxed as 100% business income instead of 50% capital gains.

Key Categories of CRA Audit Questions
When selected for a crypto audit, Canadian taxpayers often receive a long questionnaire with over 50 detailed queries. These questions aim to understand your involvement, transaction history, and tax classification. The CRA uses your responses to verify whether you reported all taxable events and followed the correct reporting rules.
Background and Involvement in Crypto
The CRA begins by trying to understand your entry into the crypto space. These foundational questions set the tone for the entire audit.
When Did You Get Involved?
This question sets the timeframe for the CRA’s review. You should respond honestly with a date or year. Mention how you learned about crypto and what motivated your initial transaction. Consistency with exchange registration and wallet creation dates is essential.
Are You An Investor, Trader, Or Miner?
This question determines whether your income should be treated as capital gains or business income. Choose one classification based on how often you trade, your intent, and whether you operate commercially. Try not to overcomplicate your role. Stick to a single category unless your activity has evolved.
What Is Your Primary Funding Source?
The CRA wants to ensure your crypto purchases are backed by reported income. Your answer should match what you have declared in prior tax returns, such as salary, savings, or loans. If you received a gift or inheritance, mention that supporting documents are available.
Wallets, Addresses, and Exchanges
Once the background is established, the CRA moves into tracing your crypto assets across platforms and wallets.
Can You List All Your Wallets And Addresses?
List every software, hardware, and custodial wallet you have ever used. Include full addresses and associated blockchains. Even old or inactive wallets should be included. Providing complete information shows transparency and reduces suspicion.
What Exchanges Have You Used?
Name all centralized and decentralized exchanges you’ve traded on. Include Canadian and international platforms. For each, provide your account email, start and end usage dates, and whether you still have access. If you no longer use an exchange, please briefly state the reason.
Do You Use Decentralized Platforms Or Mixers?
Be cautious but truthful. If you used DEXs like Uniswap or mixers like Tornado Cash, mention the platform names and why you used them. Mixing services are red flags. If used for privacy, clarify your reasons and include transaction logs, if possible.
Transaction Histories and Records
The CRA looks for a verifiable timeline of your activities, along with supporting records for each transaction type.
Can You Provide A Timeline Of All Your Trades?
You should be able to show a chronological list of transactions, including date, crypto type, amount, and platform used. Use data exports from exchanges and wallets. Spreadsheets that consolidate this information can also help during audits.
Do You Have Fiat-To-Crypto, Crypto-To-Crypto, And Goods Purchases Documented?
Yes answers should be supported with receipts, transaction IDs, or screenshots. Include purchase confirmations, swap records, and invoices for items bought with crypto. Organize documents by category and date for clarity.
Do You Maintain Records Of Cad Values At Transaction Time?
The CRA requires gains to be reported in Canadian dollars. Use historical price tools or exchange API data to convert each trade into CAD. If your software calculates this, mention it. Keep a record of exchange rates used in case of questions.
Adjusted Cost Base (ACB) and Gain Calculations
Audit focus shifts toward your gain/loss reporting methodology. These questions assess whether you followed CRA-compliant accounting practices.
How Do You Calculate Your ACB?
Describe the method you use to determine the ACB of each asset, including how you update the cost when more units are added. Ensure your explanation aligns with the information reflected in your returns.
Do You Follow CRA’s Average Cost Basis Method?
If so, state this directly and provide supporting evidence. CRA requires the averaging of costs per coin, not FIFO or LIFO. If you used a crypto tax tool to automate it, mention the tool and how it adheres to CRA rules.
Do You Have A Spreadsheet Or Software Proof?
Yes answers should be backed with exports from tools like KoinX or Excel logs. Include the date of generation, formulas used, and show that all trades and conversions are reflected correctly. Software reports should align with amounts on your field returns.
Business and Mining Related Activities
If your crypto activity includes mining or business income, the CRA will seek operational records and revenue documentation.
Do You Have Mining Receipts And Pool Agreements?
Keep receipts for all mining hardware, utility bills, and pool contracts. If you mine independently, show proof of wallet income. Ensure each item is accompanied by a matching invoice or payment confirmation.
Do You Accept Crypto Payments?
List clients or platforms through which you receive crypto. Include product or service types, invoice dates, and transaction values. Ensure that all amounts are reported as business income and converted to CAD using fair market value at receipt.
Have You Declared All Mining Rewards?
You should include all block rewards in your income for the year received. Track wallet inflows and show conversion to CAD. If using software, demonstrate how it accounts for the timing and value of each reward.
What Documentation Should You Keep Ready For A CRA Audit?
To pass a CRA crypto audit without penalties, you must maintain clear, detailed records for every transaction and activity. The CRA does not accept rough estimates or missing data. Below are the key types of documentation you should prepare in advance to defend your tax position.
Exchange Records and Wallet Histories
Exchange reports are the primary source for verifying trades and holdings. Download complete transaction histories from every centralized and decentralized exchange you’ve used. Include:
- Account opening date and KYC confirmation
- Deposit and withdrawal logs
- Trade executions (buy, sell, swap)
- Fiat conversions and CAD equivalents
For wallets, export the transaction logs, address details, and balances over time. Keep backups from both hot and cold wallets.
Transaction Receipts and Crypto Values in CAD
The CRA requires you to report crypto income and disposals in Canadian dollars. Keep a record of:
- Receipts for each crypto purchase or sale
- Historical CAD value at the time of the transaction
- Screenshots or price API data used for conversions
You should also save records of goods or services paid for with crypto, including invoices and timestamps.
Mining Income and Equipment Costs
If you mine crypto, your records must prove both income and expenses. Maintain:
- Receipts for mining hardware (GPUs, ASICs, rigs)
- Electricity bills and internet usage documents
- Mining pool payout reports
- Contract copies and timestamps of earnings
Ensure each income record includes the CAD value at the time of receiving the crypto.
Adjusted Cost Base and Capital Gain Calculations
To support your ACB method, keep detailed spreadsheets or software reports that log:
- Date and value of each acquisition
- Number of units acquired
- Fees paid and included in ACB
- Running ACB per asset type
This will be crucial to justify your capital gains calculations under the average cost basis method used by the CRA.
Proof of Business Activities (if applicable)
If you run a crypto-related business or accept crypto as payment, prepare these documents:
- Invoices issued for goods or services
- Payment confirmations in crypto
- Wallet addresses used for business
- Business registration and CRA number
- Bookkeeping records and categorized income
Ensure that all cryptocurrency income is converted into CAD using the fair market value at the time of receipt.
