Wealthsimple Crypto Tax: What the Platform Reports and What It Misses
Wealthsimple Crypto is one of the simplest Canadian crypto platforms to use and one of the easiest to file from, in theory. The platform produces a T5008 Statement of Securities Transactions automatically. In practice, the report has a single major flaw. Cost basis on coins transferred in from another wallet defaults to zero, which inflates the gain on every disposal that follows.
This guide covers exactly what Wealthsimple Crypto reports for tax purposes, what it does not, and the steps to verify before you file your Canadian, UK, or US return.
What Wealthsimple Crypto Reports
For Canadian users (the platform’s primary market), Wealthsimple issues a T5008 form by end of February each year covering all crypto disposals during the prior tax year. The T5008 shows the date of disposal, the proceeds of disposition (CAD value at sale), the adjusted cost base (where Wealthsimple has it), and a Type 4 designation in box 6 confirming non-registered account treatment.
For UK and US filers using Wealthsimple Crypto, the platform also provides a transaction history CSV export covering all buys, sells, deposits, withdrawals, staking rewards and referral bonuses. There is no UK-specific or US-specific tax form.
To export:
1. Sign in to your Wealthsimple account
2. Select Crypto in the product menu.
3. Click your profile icon, then Documents and reports.
4. Download the Transaction history CSV and the T5008 if applicable.
Where Wealthsimple Crypto Tax Reports Go Wrong
Three patterns repeat in client reviews.
- Error 1: cost basis defaults to zero on transferred-in coins. This is the single biggest issue. If you bought BTC on Coinbase in 2021 for £8,000 and transferred it to Wealthsimple Crypto in 2023, then sold it in 2024 at £40,000, Wealthsimple’s T5008 will show proceeds of £40,000 and adjusted cost base of £0. The “gain” looks like £40,000 when the real gain is £32,000. Filing on Wealthsimple’s figure alone overstates your tax by 30 percent or more. Cost basis must be manually applied from the original acquisition source. Koinly, CoinTracker, and Recap can pull from both Wealthsimple and the originating exchange to reconstruct cost basis, but the data quality depends on every wallet being connected.
- Error 2: staking and referral rewards reported in CAD only. For UK and US filers, the CSV reports values in CAD. Those need converting to GBP or USD using the spot rate at the date of receipt. Wealthsimple does not perform this conversion. Reporting staking income in CAD on a Self Assessment or 1040 return is incorrect.
- Error 3: internal transfers between Wealthsimple products treated inconsistently. Wealthsimple Cash, Wealthsimple Crypto, and Wealthsimple Trade are separate ledgers internally. Moves between products sometimes appear as withdrawals on the crypto side and are not always matched to the corresponding deposit on the Cash side. This creates phantom disposals in the CSV that look like sales but are not.
What to Verify Before Filing
Before you submit a tax return based on Wealthsimple Crypto data:
1. Match every disposal to an acquisition. If the cost basis is blank, find the original purchase wallet and add it.
2. Confirm staking and referral rewards are converted to GBP or USD at the spot rate on the receipt date.
3. Check internal Wealthsimple transfers are not double-counted.
4. For Canadian filers, confirm the T5008 adjusted cost base reflects all your prior transactions, not just the period since you first deposited to Wealthsimple.
When You Need a Specialist
If you use Wealthsimple Crypto alongside any other wallet or exchange, the platform’s tax forms in isolation are almost certainly not your full picture. Cost basis reconstruction is where most Canadian, UK, and US filers lose the most money to overstated gains.
