Step 2: Identify Taxable Events
Capital Gains Tax (CGT) Events
- Selling crypto for GBP.
- Crypto-to-crypto swaps.
- Spending crypto on goods/services.
- Gifting (except to spouses/charities).
Income Tax Events
- Staking/mining rewards.
- Airdrops (if earned via tasks).
- DeFi yield/interest.
Step 3: Calculate Average Cost Basis
HMRC uses average cost method. Example:
- Buy 1 BTC at £1,000; second BTC at £3,000 → Average cost: £2,000.
Step 4: Apply HMRC Special Rules
- Same-Day Rule: Group same-day trades; calculate average cost/revenue.
- Bed & Breakfast Rule: Re-bought assets within 30 days? Rematch sales to avoid tax avoidance.
Step 5: Deduct Eligible Fees
- Deductible: Exchange fees, gas fees for transactions.
- Non-Deductible: Hardware/software costs (unless proven essential).
Step 6: Calculate Capital Gains/Losses
- Formula:
Gain = Disposal Value - Cost Basis. - Offset Losses: Deduct losses from gains; carry forward excess losses.
Step 7: Calculate Crypto Income
- Fair Market Value: Convert rewards (e.g., 0.5 BTC mined @ £20,000/BTC = £10,000 income).
Step 8: Determine Total Tax Liability
- Combine crypto gains with other capital gains (e.g., stocks).
- Apply CGT rates (10% basic rate; 20% higher rate).
- Add crypto income to total taxable income; apply Income Tax rates (20–45%).
