Cryptocurrency CGT Explained: Your Complete Guide to Capital Gains Tax on Crypto

Understanding Cryptocurrency Capital Gains Tax (CGT)

Cryptocurrency Capital Gains Tax (CGT) is the tax levied on profits earned when you sell, trade, or dispose of digital assets like Bitcoin, Ethereum, or other altcoins. When the value of your crypto increases between acquisition and disposal, that profit constitutes a taxable capital gain. Understanding CGT rules is crucial for compliant investing and avoiding penalties from tax authorities like HMRC or the IRS.

How Cryptocurrency CGT Works: Key Triggers

Crypto CGT applies when you:

• Sell crypto for fiat currency (e.g., converting Bitcoin to GBP/USD)
• Trade one cryptocurrency for another (e.g., swapping Ethereum for Solana)
• Use crypto to purchase goods/services (e.g., buying a laptop with Bitcoin)
• Gift crypto to non-spouse individuals (above annual exemption limits)

Note: Simply holding crypto or transferring between your own wallets doesn’t trigger CGT.

Calculating Your Crypto Capital Gains

Follow this 4-step formula:

1. Determine acquisition cost: Purchase price + transaction fees
2. Calculate disposal value: Market value at time of sale/trade
3. Compute gain/loss: Disposal value – Acquisition cost
4. Apply allowable deductions: Subtract trading fees and losses

Example: Bought 1 ETH for £1,500 (with £10 fee). Sold for £2,500 (with £15 fee). Taxable gain = (£2,500 – £15) – (£1,500 + £10) = £975.

Current CGT Rates and Allowances (2023/2024)

Tax rates vary by jurisdiction:

• UK: Basic-rate taxpayers pay 10%, higher-rate taxpayers pay 20% on gains above £6,000 annual exemption
• US: Short-term gains (held <1 year) taxed as income (10-37%), long-term gains (held >1 year) at 0-20%
• Australia: 50% discount for assets held over 12 months

Always verify local thresholds as exemptions decrease annually (e.g., UK allowance drops to £3,000 in April 2024).

Reporting Crypto Gains: Compliance Essentials

Most countries require disclosure through:

• Self-assessment tax returns (UK)
• IRS Form 8949 + Schedule D (US)
• Capital gains schedule (Australia)

Keep detailed records of all transactions including dates, values, wallet addresses, and purposes for at least 6 years. Use crypto tax software like Koinly or CoinTracker to automate calculations.

7 Strategies to Minimize Cryptocurrency CGT

1. Utilize annual exemptions: Spread disposals across tax years
2. Hold long-term: Benefit from reduced long-term CGT rates
3. Offset losses: Deduct capital losses from gains in same tax year
4. Bed and breakfasting: Rebuy assets after 30 days to reset cost basis
5. Gift to spouse: Transfers between spouses are CGT-free
6. Invest through ISAs/pensions: Use tax-advantaged accounts where permitted
7. Donate to charity: Avoid CGT while claiming income tax relief

Frequently Asked Questions (FAQ)

Do I pay CGT if my crypto loses value?

No, but you can report capital losses to offset future gains. Losses can be carried forward indefinitely in most jurisdictions.

Is staking rewards income subject to CGT?

Staking rewards are typically taxed as income at receipt. When later sold, CGT applies to gains from the reward’s market value at acquisition.

How is DeFi taxed?

Providing liquidity, yield farming, and token swaps trigger CGT events. Each pool exit or token exchange is considered a disposal.

What happens if I don’t report crypto gains?

Penalties include fines (50-100% of owed tax), interest charges, and criminal prosecution in severe cases. Most tax authorities receive exchange data via automatic reporting systems like DAC8.

Are NFTs subject to CGT?

Yes, NFTs are treated as taxable crypto assets. Profits from sales follow standard CGT rules, though creator royalties may have different tax treatment.

Always consult a crypto-specialized accountant for personalized advice, as regulations evolve rapidly. Proper CGT management protects your investments while ensuring full compliance with global tax authorities.
