Moving countries with crypto: what to watch

Residency comes first

Every country page on this site describes the rules for that country’s tax residents — and whether you are one is determined by each country’s own tests: days present, available homes, centre of vital interests. The UK runs the Statutory Residence Test; Australia applies several residency tests; Germany asks about a domestic residence or habitual abode. The same crypto disposal can produce entirely different outcomes under different residencies — so the first question in any cross-border situation is always: whose tax resident were you, that year?

The special cases

• US citizenship-based taxation: the US taxes citizens and green card holders on worldwide income even while living abroad and using foreign exchanges — with foreign account reporting obligations layered on top.
• Double taxation and treaties: where two countries both claim the same gain, a double tax agreement and foreign tax credits can relieve the overlap — subject to the treaty’s actual terms and the asset’s classification.
• Exit taxes: several countries operate exit taxes or deemed-disposal-on-departure rules. Whether and how these reach privately held crypto varies by country and keeps changing — never assume either way.

The year you move

Relocation year is the minefield: you may be resident in two countries in sequence — or, briefly, in both at once — and whether a disposal fell before or after the move can decide which country taxes it and whether a relief survives (does Germany’s one-year clock still help you? Australia’s 12-month discount?). These timing questions are irreducibly case-specific. Engage an adviser who knows both systems before the move, while the timing of disposals can still be chosen rather than explained.

Data follows you

The old assumption — new country, new exchange, old tax authority none the wiser — is expiring on a schedule. Under CARF and DAC8, platforms report account and transaction data to their local authority annually, and authorities exchange it automatically across borders. Crossing a border no longer makes holdings invisible; handling both countries’ filings accurately is the durable strategy.

Checklist

• Establish your tax residency for each relevant year, using the official tests where needed.
• US citizens and green card holders: assess worldwide filing and foreign account obligations separately.
• Record the move date and the dates and market values of disposals around it.
• Check for an applicable double tax treaty and foreign tax credits.
• Engage a licensed adviser familiar with both jurisdictions — one of the few situations where the fee is unambiguously cheaper than the mistake.
