Understanding Cost Basis in Cryptocurrency

In the world of cryptocurrency, cost basis refers to the original value of an asset for tax purposes. This value typically includes the purchase price plus any associated fees. When you sell or trade crypto, the cost basis is subtracted from the sale price to determine your capital gain or loss. For platforms like Coinbase, understanding your cost basis is crucial for accurate tax reporting. However, the process of locating this information can be confusing for new users.

Navigating Coinbase’s Tax Reporting Tools

Coinbase offers several tools to help users track and calculate their cost basis. One of the primary tools is the Tax Center, which became available to U.S. users in recent years. To access this feature:

• Log into your Coinbase account.
• Click on the Reports tab in the top navigation bar.
• Select Tax Center from the dropdown menu.

Within the Tax Center, you’ll find a summary of your taxable events, including sales, trades, and income. Cost basis data is automatically calculated using the specific identification method, which allows you to choose which units of cryptocurrency you are selling or trading. If you don’t select specific units, Coinbase defaults to the first-in, first-out (FIFO) method.

Locating Cost Basis in Transaction Details

For individual transactions, you can manually check the cost basis by reviewing the details of each trade or sale:

• Go to the Accounts section.
• Select the specific cryptocurrency you’re interested in.
• Click on the Transaction History tab.
• Locate the transaction where you sold or traded the asset.

In the details, you’ll see the purchase date, amount, price, and fees associated with the original acquisition. These factors are used to determine the cost basis. It's important to note that Coinbase calculates cost basis based on the date and price of acquisition, and includes fees to ensure accuracy for tax purposes.

Exporting Transaction History for External Use

If you prefer to use third-party tax software or spreadsheets to calculate your cost basis, you can export your transaction history from Coinbase:

• Navigate to the Reports section.
• Choose Transaction History.
• Click on the Export CSV button.

This CSV file includes all your transactions, including buys, sells, and transfers. Each row contains the date, type, amount, and cost basis if available. Some rows may not show a cost basis if the transaction was a transfer or deposit without a taxable event. In such cases, you may need to manually input the cost basis based on prior transactions or external records.

Using Coinbase Pro for Advanced Cost Basis Tracking

For more experienced traders, Coinbase Pro offers a more granular view of transaction history and cost basis. The process involves:

• Logging into Coinbase Pro.
• Clicking on the History tab.
• Selecting Fills or Transfers to view detailed records.

In this interface, you can see the exact price, fees, and time of each trade, which can be used to manually calculate cost basis. While Coinbase Pro does not display cost basis directly, the level of detail provided allows for more precise manual tracking, especially for users who want to apply different accounting methods like specific ID, FIFO, LIFO, or average cost.

Common Questions About Cost Basis on Coinbase

What is the default cost basis method used by Coinbase?

Coinbase uses the specific identification method by default, allowing users to select which units were sold. If no selection is made, it defaults to FIFO (First In, First Out).

Can I change the cost basis method on Coinbase?

Yes, users can choose which units they are selling when making a trade or sale. This is done by selecting the specific transactions associated with the coins you’re selling, effectively customizing your cost basis.

Does Coinbase report cost basis to the IRS?

As of now, Coinbase does not report cost basis directly to the IRS, but it does provide detailed tax reports that include cost basis calculations. These reports can be used when filing your taxes.

Why is cost basis missing for some transactions?

Cost basis may not be available for certain transactions like transfers between wallets or airdrops, where no initial purchase occurred. In these cases, users may need to manually determine the fair market value at the time of receipt to establish a cost basis.
