Tax year: what it means for crypto tax
The tax year is the 12-month period your tax return covers. It does not always match the calendar year, some countries run to April or another month, which affects which disposals fall into which return.
General information, not tax advice. Crypto tax rules differ by country and change over time, verify against your country's guidance or a qualified advisor.

An example
In the UK the tax year runs to early April, so a disposal in March and one in May fall into different returns.
Why it matters for your tax
The tax-year boundary matters for timing: realising a gain or loss on one side of it or the other can change which year it is taxed in, where your rules allow.
CryptaTax handles this automatically across your wallets and exchanges, so the concept is applied consistently without you tracking it by hand. Try the crypto tax calculator →
