Yes, cryptocurrency is taxable in the United States. The IRS treats cryptocurrency as property, meaning transactions involving crypto are subject to taxation, similar to stocks or other capital assets. Taxable events include selling crypto for cash, converting one cryptocurrency to another, spending crypto on goods or services, receiving crypto as income (e.g., from mining, staking, or payments), and more. The tax owed depends on how the cryptocurrency was acquired and used. Gains from selling or converting crypto are taxed as capital gains, either short-term or long-term based on the holding period. Income received in crypto is taxed at your regular income tax rate. However, non-taxable events include buying and holding crypto, transferring it between your own wallets, or donating it to qualified charities. Proper record-keeping and consulting a tax professional are crucial to ensure compliance with evolving IRS guidelines.
