How Cryptocurrency Is Taxed in the U.S.

The IRS classifies cryptocurrencies as property, not currency. This means every time you sell, trade, or use crypto for purchases, it may trigger a taxable event. Taxes are applied to the capital gains—the difference between what you paid (cost basis) and what you received (fair market value) at the time of disposal.

There are two types of capital gains:

Understanding Crypto Capital Gains and Losses

A capital gain occurs when you sell crypto for more than its cost basis. Conversely, a capital loss happens when you sell for less. Both must be reported on your tax return.

Capital losses can be powerful tools:

This process, known as tax-loss harvesting, allows strategic investors to reduce their overall tax bill legally.

Holding crypto long-term can significantly lower your effective tax rate—making "HODLing" a sound financial strategy.


How Crypto Tax Brackets Work

The U.S. uses a progressive tax system, meaning only the portion of income within each bracket is taxed at that rate. For example, a single filer earning $50,000 doesn’t pay 22% on all income—just the amount falling into the 22% tier.

This marginal taxation ensures fairness and prevents abrupt tax spikes. Understanding this helps you estimate liabilities and plan trades accordingly.


Calculating Crypto Gains: Cost Basis & Fair Market Value

To calculate gains, use this formula:

Capital Gain = Fair Market Value (at disposal) – Cost Basis

Your cost basis includes the purchase price plus fees. The IRS allows several methods to determine which coins are sold first:
