The Principle Behind Cost Basis

In US crypto taxation, "cost basis" is the purchase price of your cryptocurrency, essential for calculating capital gains or losses.

A higher cost basis reduces capital gains, potentially lowering your tax bill, while a lower cost basis increases gains and taxes. Accurate tracking of cost basis is crucial for compliance and informed tax strategy.

Different methods, like FIFO, LIFO, HIFO, Specific Identification, and Weighted Average Cost, determine cost basis. These will be detailed in the article.

IRS's Perspective on Cost Basis Methods

The IRS treats cryptocurrency as property, similar to stocks or real estate, for capital gains and losses. While the IRS hasn't specified preferred cost basis methods for crypto, it emphasizes consistency and accuracy.

Keep detailed records of all crypto transactions—dates, amounts, costs, and sales proceeds. Accurate tracking, especially for specific identification, is crucial. Tools like Blockpit's Crypto Tax Calculator can help. Inaccurate reporting can lead to penalties, interest, and audits. Properly calculate and report gains or losses to avoid issues.

Different Cost Basis Methods and Their Impact

First In, First Out (FIFO)

FIFO assumes the earliest purchased cryptocurrency is sold first. If you buy 1 Bitcoin in January at 30,000$ and another in June for 40,000$, then sell one in August, FIFO uses the 30,000$ cost basis.

Impact: Can benefit from lower long-term capital gains tax rates.

Usage: Common in consistent buying and selling scenarios.

Last In, First Out (LIFO)

LIFO assumes the most recently purchased cryptocurrency is sold first. If you buy 1 Bitcoin in January at 30,000$ and another in June for 40,000$, then sell one in August, LIFO uses the 40,000$ cost basis.

Impact: May lead to higher short-term gains in rising markets.

Usage: Suitable for rapid trading but can result in higher short-term taxes.

Highest In, First Out (HIFO)

HIFO selects the highest cost cryptocurrency units for sale first. If you bought Bitcoins at 20,000$, 30,000$, and 40,000$, selling one uses the 40,000$ cost basis.

Impact: Minimizes capital gains in rising markets.

Usage: Reduces taxes initially, but may increase future taxes. Requires thorough record-keeping.

Specific Identification (SpecID)

SpecID allows choosing the exact units sold based on their purchase details.

Impact: Provides flexibility to manage capital gains effectively.

Usage: Ideal for active trading, but requires meticulous documentation.

Weighted Average Cost

Averages the cost by dividing the total spent by the number of units. If you buy one Bitcoin at 30,000$ and another at 40,000$, the average cost is 35,000$.

Impact: Simplifies tracking, ideal for regular purchases.

Usage: Not suitable for volatile markets. Must be used consistently for each asset.

Example Calculation of Cost Basis Methods

• October 2023: Buy of 1 BTC for 30,000$
• December 2023: Buy of 2 BTC for 40,000$
• June 2024: Buy of 1 BTC for 60,000$
• December 2024: Sell of 1 BTC for 45,000$

*For the Weighted Average: You spent 170,000$ for 4 BTC, averaging 42,500$ per BTC.

For the December 2024 sale:

• FIFO: Report a gain of 15,000$
• LIFO or HIFO: Report a loss of 15,000$
• Weighted Average: Report a gain of 2,500$

Choosing the Right Cost Basis Method

Trading Habits: Active traders might prefer HIFO; occasional traders may opt for FIFO or LIFO.

Tax Implications: HIFO can reduce short-term taxes in rising markets but may impact future transactions. Consider both short-term and long-term capital gains rates.
