Cryptocurrency investors often grapple with choosing the right accounting method to optimize their tax liabilities. This guide breaks down FIFO, LIFO, and HIFO, helping you understand their pros, cons, and tax implications.
How Cryptocurrency Taxation Works
When you sell or trade crypto, you incur capital gains or losses based on the price difference between acquisition and disposal. The IRS treats cryptocurrency as property, meaning:
- Capital Gains Tax: Applied to profits from sales.
- Capital Losses: Can offset gains or reduce taxable income (up to $3,000 annually).
Calculating Gains/Losses
Formula: Capital Gain/Loss = Proceeds (Sale Price) - Cost Basis (Purchase Price)

What Are Cost Basis Methods?
Cost basis methods determine which units of crypto are sold first, impacting your taxable gains. Key methods:
FIFO (First-In-First-Out)
- Sells oldest acquisitions first.
- Example: Buy 1 ETH at $2,250, then another at $2,500. Selling 1 ETH under FIFO uses the $2,250 cost basis.
LIFO (Last-In-First-Out)
- Sells most recent acquisitions first.
- Best for rising markets (lowers taxable gains).
HIFO (Highest-In-First-Out)
- Sells units with the highest cost basis first.
- Maximizes tax savings by minimizing gains.
Comparison Table
| Method | Scenario | Tax Impact |
|--------|-------------------|---------------------|
| FIFO | Prices falling | Higher gains |
| LIFO | Prices rising | Lower gains |
| HIFO | Volatile markets | Lowest gains |
Per-Wallet Cost Basis (2025 Update)
Starting in 2025, the IRS mandates the per-wallet method:
- Sales must match buys from the same wallet/exchange.
- Example: Buying BTC on Exchange A ($20K) and Exchange B ($25K). Selling from Exchange B uses the $25K cost basis.
FAQs
1. Which method saves the most on taxes?
HIFO typically minimizes gains by prioritizing high-cost-basis sales.
2. Can I switch methods yearly?
Yes, but consult a tax professional to avoid errors like double-counting cost basis.
3. Are crypto-to-crypto transfers taxable?
No, but cost basis carries over to the new wallet.
4. Is average cost basis allowed in the U.S.?
No—only FIFO, LIFO, and HIFO are permitted.
Choosing the Right Method
- FIFO: Simple, IRS-default, benefits long-term holders.
- LIFO: Ideal for short-term traders in bullish markets.
- HIFO: Best for active traders seeking tax efficiency.
