US Tax Calculation Methods
Cost Basis Tracking Methods
First-In-First-Out (FIFO) – IRS Default:
Example Transaction History:
Jan 1: Bought 1 BTC at $30,000
Feb 1: Bought 1 BTC at $40,000
Mar 1: Sold 0.5 BTC at $50,000
FIFO Calculation:
Sold 0.5 BTC from Jan 1 purchase
Cost Basis: $15,000 (0.5 × $30,000)
Proceeds: $25,000 (0.5 × $50,000)
Capital Gain: $10,000
Last-In-First-Out (LIFO) – Alternative Method:
Same transaction history:
LIFO Calculation:
Sold 0.5 BTC from Feb 1 purchase
Cost Basis: $20,000 (0.5 × $40,000)
Proceeds: $25,000
Capital Gain: $5,000
Tax Savings with LIFO: $5,000 less gain
Specific Identification – Most Flexible:
- Choose exact Bitcoin units being sold
- Optimize for tax efficiency
- Requires detailed record-keeping
- Must identify at time of transaction
Short-term vs. Long-term Capital Gains
Short-term (≤1 year holding):
- Taxed as ordinary income
- Rates: 10-37% (2025 tax brackets)
- No preferential treatment
Long-term (>1 year holding):
- Preferential tax rates
- Rates: 0%, 15%, or 20% based on income
- Significant tax savings for most taxpayers
2025 Long-term Capital Gains Brackets:
| Income Level (Single) | Income Level (Married) | Tax Rate |
|---|---|---|
| $0 – $47,025 | $0 – $94,050 | 0% |
| $47,025 – $518,900 | $94,050 – $583,750 | 15% |
| $518,900+ | $583,750+ | 20% |

US Tax Optimization Strategies
Tax Loss Harvesting
Strategy: Sell Bitcoin at a loss to offset gains
Example:
Portfolio Status December 2024:
- Bitcoin A: $10,000 gain (if sold)
- Bitcoin B: $3,000 loss (if sold)
- Altcoin C: $2,000 loss (if sold)
Tax Loss Harvesting Action:
- Sell Bitcoin B and Altcoin C
- Realize $5,000 in losses
- Offset $5,000 of Bitcoin A gains
- Net taxable gain: $5,000 instead of $10,000
Wash Sale Rules:
- Traditional wash sale rules don’t apply to Bitcoin (as of 2025)
- Can immediately repurchase Bitcoin after selling for loss
- Proposed legislation may change this in future
Long-term Holding Strategy
Benefits:
- Preferential tax rates (0%, 15%, 20% vs. up to 37%)
- Significant tax savings for most taxpayers
Example Savings:
$100,000 Bitcoin gain:
Short-term (25% bracket): $25,000 tax
Long-term (15% rate): $15,000 tax
Tax Savings: $10,000 (40% reduction)
Charitable Giving Strategy
Donating Appreciated Bitcoin:
- No capital gains tax on donated amount
- Charitable deduction at fair market value
- Must itemize deductions to benefit
Example:
Bitcoin purchased for $10,000, now worth $50,000:
Direct donation to qualified charity:
- Capital gains avoided: $40,000 × 15% = $6,000 saved
- Charitable deduction: $50,000 (if itemizing)
- Total tax benefit: Substantial
