Coinbase Survey Finds Over Half of Users Do Not Understand Crypto Tax Rules

Tax treatment of cryptocurrency transactions involves determining whether assets were sold or exchanged and calculating their cost basis, though not every type of transaction creates a taxable event. A 2026 tax-preparation report from Coinbase and crypto tax platform CoinTracker found that investors still have a limited understanding of filing rules, potentially increasing the risk of inaccurate or incomplete returns and additional tax bills.

The latest 2026 survey found that only 49% of Coinbase users knew that selling cryptocurrency is taxable, meaning more than half of respondents did not understand this basic rule. Nearly one-quarter mistakenly believed that simply transferring assets to another wallet would trigger a taxable event, while only 35% had ever adjusted an asset’s cost basis, highlighting significant gaps in tax preparation.
