What Is Cost Basis?
The cost basis is the original value of an asset, including purchase price, transaction fees, gas fees, and other acquisition costs. For crypto, it also applies to:
– Mining rewards
– Staking income
– Airdrops and forks
Why Cost Basis Matters
- Tax Reporting: Determines capital gains/losses for accurate tax filings.
- Portfolio Management: Helps track investment performance.
- Loss Harvesting: Enables offsetting gains with losses to reduce tax liability.
How to Calculate Cost Basis
1. First-In, First-Out (FIFO)
- Sells the oldest assets first.
- Example: If you bought Bitcoin at $10,000 (2021) and $50,000 (2023), FIFO assumes the $10,000 units are sold first.
2. Last-In, First-Out (LIFO)
- Sells the most recent purchases first.
- Best for: Rising markets to reduce taxable gains.
3. Specific Identification
- Choose which units to sell (requires meticulous recordkeeping).
- Ideal for: Strategic tax planning.
| Method | Best Use Case | Complexity |
|---|---|---|
| FIFO | Default in many countries | Low |
| LIFO | High-price acquisitions | Medium |
| Specific ID | Custom tax strategies | High |
👉 Pro Tip: Use crypto tax software to automate calculations.
