Wallet and Treasury Structuring for Canadian Crypto Businesses

The most expensive habit in this industry is one wallet doing everything. Personal spending, company revenue, treasury, gas, all through the same address.

It is not expensive because a rule forbids it. No rule does. It is expensive because of what happens two years later, when somebody has to prove which side of the line each transaction fell on, from memory, with an exchange that has since closed.

This guide is about the structure that prevents that, and about the specific places where mixing personal and corporate crypto stops being untidy and starts being a tax bill.

What the CRA actually requires you to keep

Start here, because the record-keeping rules drive the structure.

For every transaction, the CRA requires:

• the number of units and the type of crypto-asset
• the date and time
• the Canadian dollar value at that time
• a description of the transaction and who the other party was
• the addresses associated with each digital wallet used

Plus, annually, the opening and closing balance of each asset with its cost. All retained for at least six years after the end of the tax year concerned.

If you are running a hot wallet, a multisig treasury, program-derived addresses and a personal wallet you occasionally pay gas from, that register is a real document you have to maintain, not a formality.

Two practical points that follow.

Moving tokens between your own wallets

The common question: is moving SOL from one wallet I control to another a taxable disposition?

The answer is almost certainly no, and it is worth being precise about why, because the CRA has not published anything on this point specifically.

A disposition under the Income Tax Act excludes a transfer where there is no change in beneficial ownership. Move a token between two wallets you beneficially own and beneficial ownership has not changed. The CRA's own descriptions of disposition consistently say transfer its ownership, not transfer it, and its table of acquisition and disposition events does not list self-transfers at all.

What is clearly a disposition:

• Trading or swapping one token for another. SOL to USDC is taxable even though no dollars moved.
• Converting to Canadian or US dollars.
• Paying for goods or services in tokens.
• Gifting or donating.

One genuinely unsettled corner: the gas you pay in SOL to make a self-transfer is arguably a disposition of that SOL. The CRA has said nothing. For most people the amounts are trivial. For a business doing high transaction volumes on Solana they are not, in aggregate. Pick a treatment, document it, and apply it consistently, which at least aligns with what the CRA asks for on valuation methods.

One cost base pool per taxpayer, not per wallet

Canadian tax treats identical properties as a pool. You do not track individual units. You calculate the average cost across everything you hold of that property, and that average is what a disposition is measured against. The CRA sets out the identical property rule for shares and units, and applies averaging language to crypto in its own material.

What this means in practice:

• Your SOL is one pool, across every wallet and exchange you hold it in. Splitting it across five addresses does not create five cost bases. The CRA has not said this about crypto in terms, but it follows directly from how identical property works, and the form your ownership takes does not defeat the identity of the property.
• A corporation and its shareholder are different taxpayers, so they have separate pools. This is the most useful practical consequence in this guide. Your personal SOL and your company's SOL are tracked entirely separately, which is another reason the wallets should not be mixed.
• NFTs are not identical property. Each one is tracked on its own.
• Wrapped and liquid-staking tokens are different property from the underlying. Do not pool a liquid-staking derivative with native SOL. The CRA has published nothing on wrapping, so this is an area to be careful in.

One trap worth naming. If you sell a token at a loss personally while a corporation you control buys the same token inside the thirty day window either side, the superficial loss rules can deny your loss. Affiliated persons include a spouse and a corporation you control. This is an easy mistake to make without realising it.

Where commingling stops being untidy and becomes expensive

Money or property flowing from a corporation to its shareholder is caught by one of two provisions:

• A shareholder benefit. The value is included in your personal income, and critically the corporation gets no offsetting deduction, unlike a salary or an employee benefit. You are taxed personally on money the company already paid tax on.
• A shareholder loan. Also an income inclusion, but curable: if the loan is genuinely repaid within one year after the end of the corporation's tax year in which it arose, and the repayment is not part of a series of loans and repayments, the inclusion does not apply.

So a founder who casually spends company SOL on something personal has, depending on how it is characterised, either created a permanent double-tax problem or a repayable loan. The difference is worth a great deal of money, and the CRA has published nothing at all on how it characterises crypto movements between a corporation and its shareholder. What helps is contemporaneous documentation: a shareholder loan account, recorded when it happens, repaid in the window.

There is a related problem with no clean answer. A wallet is controlled by a key, not registered in anyone's name. Establishing that a given address belongs to the company rather than to you personally is an evidential question the CRA has never addressed. A corporate resolution designating the treasury addresses, and consistent treatment of those addresses in the company's books, is the practical answer. It is professional practice, not authority.

Moving crypto into your own company

Worth flagging because founders do this without thinking and it can be costly.

You and your corporation do not deal at arm's length, and beneficial ownership does change. So the no-change-in-ownership exception does not help you. Where you transfer property to a non-arm's-length person for less than fair market value, the Act deems you to have received proceeds equal to fair market value.

There is a mechanism to defer this, a section 85 rollover, which requires a joint election on Form T2057, filed by a deadline tied to the parties' returns, with at least one share taken back as consideration. It is not automatic and it is not something to attempt casually. We should also be straight with you that the CRA has not confirmed anywhere that crypto-assets are eligible property for a section 85 election, and that valuing a thin-liquidity token for this purpose is exactly the kind of number that gets reassessed.

Going the other way is harder still. There is no rollover out of a corporation, and the transfer will generally also be a shareholder benefit or loan. Getting crypto into a company is easier than getting it out. Decide before you move it.

Foreign property reporting, where the honest answer is that nobody knows

If you hold more than 100,000 dollars of specified foreign property at any point in the year, you file a T1135. Two points before the hard part:

• The threshold is cost, not value. The CRA is explicit that it is the cost amount, generally the adjusted cost base. Tokens with a 60,000 dollar cost and a 400,000 dollar value are below the threshold on cost.
• Penalties are serious, and a missed filing extends the CRA's reassessment window by three years.

Now the hard part. Is crypto foreign property?

The CRA has said crypto is capable of being specified foreign property, that whether it is situated outside Canada is "complex" and depends on the facts including whether it is held through an intermediary, and that crypto held through Canadian-resident, CSA-regulated platforms will typically not be treated as held outside Canada. It has not committed to publishing more.

Because the penalty exposure is asymmetric, there is no penalty for disclosing something you did not have to, and substantial penalties plus an extended reassessment window for the reverse, the cautious route is usually to disclose where situs is genuinely ambiguous. That is a decision to make deliberately, with your accountant, not one to default into.

The argument that the CRA cannot see it no longer works

In 2021 the Federal Court authorised the CRA to require a Canadian exchange to hand over, for its larger customers, complete trading records, KYC documentation and customer deposit addresses. Once the CRA has deposit addresses, on-chain analysis reaches well past the exchange's own records.

The Crypto-Asset Reporting Framework goes further. Under legislation currently before Parliament it is scheduled to apply from 2027, with the first platform returns due in May 2028. That obligation sits on the platforms, not on individual builders, but the effect is that exchange activity becomes visible by default.
