Mathematical Formula for Crypto Capital Gains
Capital gain or loss on a digital asset is calculated using the following cost-basis equation:
Worked Example: Ethereum Trade Analysis
Buy: 1.5 ETH bought for £2,000 + £20 gas fee = £2,020 Cost Basis
Sell: 1.5 ETH sold for £3,500 − £30 fee = £3,470 Net Proceeds
Capital Gain: £3,470 − £2,020 = £1,450 Profit
Estimated Tax (at 20% rate): £1,450 × 0.20 = £290 Tax Liability.

Crypto Tax FAQs
Clear up confusion regarding tax reporting and capital gains.
What events trigger a taxable crypto event?
Taxable events generally include selling cryptocurrency for fiat currency (USD, INR, EUR), trading one crypto token for another (e.g. BTC to ETH), or using cryptocurrency to pay for real-world goods and services.
Do I pay tax on cryptocurrency if I simply buy and hold?
No. Purchasing cryptocurrency and holding it in a private hardware wallet or exchange account is not a taxable event. Taxes are only triggered upon disposal (selling, trading, or spending).
How are gas fees and exchange transaction fees accounted for?
Network gas fees and exchange transaction fees can generally be added to your initial purchase cost basis (or subtracted from sale proceeds), which reduces your net taxable capital gain.
Can capital losses in crypto offset future capital gains?
In many jurisdictions like the United States (IRS), capital losses can offset capital gains. In India (under Section 115BBH), losses from Virtual Digital Assets (VDA) cannot be set off against other gains or carried forward, so tax rules vary significantly by country.
