Crypto tax basics: what creates a taxable event
Selling is not the only thing that triggers tax. Swaps, spending and in many places mining income and staking rewards all count. General principles, not advice.
Quick answer
In most jurisdictions, disposing of crypto is taxable — including swapping one coin for another and spending it. Mining and staking rewards are frequently taxed as income when received, then again on disposal.
Rules vary enormously by country and change often. What follows is the general shape, not advice, and not a substitute for someone who knows your jurisdiction.
Disposals, not just sales
The most expensive misunderstanding is thinking tax only applies when you cash out to fiat. In most jurisdictions a disposal includes swapping one crypto for another and spending crypto on goods. People who traded actively between coins without touching fiat have discovered large liabilities they never anticipated.
Mining and staking income
Rewards are frequently treated as income at their value when received, which establishes a cost basis. Selling later is then a separate disposal against that basis. This means a miner can owe tax on income while the asset has since fallen — see the profitability guide, because tax is a real cost that belongs in the calculation and is almost never in it.
Records
Keep date, amount, value in your local currency, and counterparty for every transaction, at the time. Reconstructing years of activity from exchange exports after the fact is the single most common and most expensive problem people bring to accountants, and some of those exchanges will no longer exist.
What we are not doing
Telling you what you owe. Jurisdictions differ on nearly every point above, and the rules move. Take this as a map of what to ask a professional rather than an answer.

- Record keeping at the time is far cheaper than reconstruction later.

Frequently asked questions
Is swapping one coin for another taxable?
In most jurisdictions yes, it is a disposal of the first asset. Check your local rules.
Do I owe tax if I only bought?
Buying and holding generally does not create a taxable event. Disposal does.
