Cryptocurrency Tax Guide: Country-by-Country Rules, Cost Basis & Legal Tax Strategies
Cryptocurrency Tax Guide
The myth that crypto is untraceable is dangerously wrong. Tax authorities in the US, UK, EU, and Asia now receive transaction data from major exchanges — and retroactive enforcement is accelerating. Understanding your obligations now prevents far larger problems later.

3. Cost Basis Methods
How you calculate your “cost basis” dramatically affects your taxable gain.
| Method | How It Works | Best For |
|---|---|---|
| FIFO (First In, First Out) | Oldest coins sold first | Long-term holders; legally required in some countries |
| HIFO (Highest In, First Out) | Highest-cost coins sold first | Minimizes taxable gains (US: must track specific lots) |
| Average Cost | Average purchase price | Simpler calculation; required in some countries |
| Specific Identification | Choose exact lots to sell | Maximum flexibility; requires detailed records |
Calculation Example (FIFO)
| Date | Transaction | Price | Qty | Cost Basis |
|---|---|---|---|---|
| Jan 1 | Buy | $20,000 | 1 BTC | $20,000 |
| Jun 1 | Buy | $35,000 | 1 BTC | $35,000 |
| Sep 1 | Sell | $50,000 | 1 BTC | Sell Jan lot: gain = $30,000 |

5. Tax Loss Harvesting
Tax Loss Harvesting (TLH) means selling losing positions to realize losses that offset gains.
Scenario:
- Bitcoin gain: +$15,000
- Ethereum loss: -$8,000
- Net taxable gain: 8,000)
Unlike stocks in the US, crypto has no wash-sale rule — you can sell at a loss and immediately repurchase the same asset without losing the tax benefit. This makes TLH far more powerful for crypto than equities.
