When to hire a crypto accountant

Quick answer

Consider an accountant if: you have heavy DeFi or staking, possible trading income status, an HMRC enquiry, cross-border residence, or simply value time over cost. Bring CSV exports, wallet lists and prior returns. Verify they are ICAEW/ACCA/CTA qualified with crypto experience.
