In most countries, cryptocurrency is treated as property for tax purposes. This means you must pay capital gains tax on the profit you make when you sell, trade, or otherwise dispose of your crypto.

How are crypto taxes calculated?

Taxes are calculated on the 'capital gain' which is the Selling Price minus the Purchase Price and any transaction fees. If you made a profit, you owe a percentage of that profit based on your country's tax bracket.

Can I deduct transaction fees?

Yes, generally transaction (gas) fees and exchange trading fees can be added to your cost basis or deducted from your sale proceeds, reducing your overall taxable gain.

What if I lost money?

If you sell crypto for less than you paid for it, it's called a capital loss. In many tax jurisdictions, capital losses can be used to offset capital gains, and sometimes even ordinary income, reducing your overall tax bill.

Do I pay tax if I just hold?

No. Simply buying cryptocurrency and holding it in a wallet or exchange does not trigger a taxable event. Taxes are only applied when you sell, trade for another crypto, or use it to buy goods/services.

Mathematical Formula for Crypto Capital Gains

Capital gain or loss on a digital asset is calculated using the following cost-basis equation:

Adjusted Cost Basis = Original Purchase Price + Buy Fees

Net Sale Proceeds = Sale Price − Sell Fees

Capital Gain / Loss = Net Sale Proceeds − Adjusted Cost Basis

Tax Owed = Capital Gain × Tax Rate (%)

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 & Compliance Advisory

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.
