Crypto Tax Guide 2026: What You Actually Owe

Sold crypto at a profit? You probably owe capital gains tax. Here's how it works in plain English, plus a free calculator to estimate your bill.

The basic rule

When you sell, trade, or spend crypto for more than you paid for it, the profit is a capital gain. You owe tax on that gain. When you sell for less than you paid, it's a capital loss - and you can use it to offset other gains.

Tax rates by country (2026)

What counts as a taxable event

• Selling crypto for fiat (USD, EUR, etc.)
• Trading one crypto for another (BTC to ETH = taxable)
• Spending crypto on goods or services
• Earning crypto (mining, staking, airdrops) - taxed as income

What is NOT taxable

• Buying crypto with fiat and holding it
• Transferring between your own wallets
• Donating crypto to charity (may get a deduction)

How to reduce your crypto tax bill

• Hold for 1+ year (in the US and Germany, long-term rates are much lower or zero)
• Harvest losses - sell losing positions to offset gains
• Use HIFO accounting (highest in, first out) to maximize your cost basis
• Relocate to a 0% jurisdiction (UAE, Singapore, Portugal was 0% until recently)
• Donate appreciated crypto - avoid gains tax and get a deduction
