- From 2026, EU DAC8 and the OECD Crypto-Asset Reporting Framework (CARF) mandate automatic cross-border sharing of user balances, fiat off-ramps, and on-chain withdrawal addresses with UK tax authorities.
- Relocating tax residency out of UK requires reviewing deemed disposition / Exit Tax rules and reconciling historical cost basis under TCGA 1992 Section 104 (Share Pooling), Section 105 (Same-Day) & Section 106A (30-Day Bed & Breakfasting).
- When changing country of residence, update KYC tax residency on Kraken Pro UK rather than liquidating to £ to avoid unnecessary taxable disposal events.
