Crypto Taxes When Moving Countries: Exit Tax, Residence and Cost Basis

Moving with crypto is not a one-date switch from a high-tax country to a low-tax country. The correct result depends on when residence ends and begins, whether two countries claim the same period, whether departure law deems a sale, how the destination carries cost basis, and when each disposal actually occurs. This 2026 guide replaces generic relocation claims with a practical, evidence-based workflow.

The core rule: map facts and dates before rates

A relocation does not automatically make unrealized crypto gains taxable, tax-free, or revalued. Three independent systems must be tested:

1. The departure country: when its residence ends, whether it taxes a deemed disposal, whether temporary non-residence or source rules continue, and which final forms are required.
2. The destination country: when residence begins, what cost and acquisition date it recognizes, and how it classifies spot, staking, DeFi, NFTs, derivatives, and business activity.
3. The overlap: whether both countries claim residence or a transaction, whether a treaty applies, and whether exemption or foreign-tax-credit relief is available.

The blockchain does not assign tax residence. An exchange account's country setting, IP address, bank account, residence visa, or tax certificate can be evidence, but none replaces the full domestic-law and treaty analysis.

When does tax residence actually change?

Residence is country-specific. Common connecting factors include an available home, days present, habitual abode, family and personal relations, economic relations, employment, business management, and immigration status. A 183-day count is only one possible test. Some countries can treat a person as resident from the first qualifying day; others apply split-year, part-year, or full-year rules.

If two countries treat the person as resident under domestic law, the applicable income-tax treaty may contain tie-breaker tests such as permanent home, centre of vital interests, habitual abode, nationality, and competent-authority agreement. The sequence and wording vary by treaty. A treaty outcome also does not necessarily settle social security, wealth tax, state or cantonal tax, company residence, VAT/GST, or disclosure duties.

Build a residence evidence file

• travel calendar and passport or border records,
• old and new home ownership or lease documents,
• registration and deregistration confirmations,
• location of spouse, dependants, work, business, and company management,
• health insurance, utilities, vehicle, telephone, memberships, and banking records,
• tax-residence certificates and the legal test supporting them,
• a written conclusion for any dual-residence period.

Record exact dates, not merely "moved in June." A sale at 23:58 UTC can fall on a different local date, and an exchange execution, contract settlement, or on-chain transfer can represent different legal events.

Departure tax is not one universal crypto rule

"Exit tax" describes several different mechanisms. A country may deem particular assets sold at fair market value, preserve taxing rights for a later sale, recapture gains if the person returns within a defined period, tax only certain company shareholdings, or impose no general departure charge on private tokens. The taxpayer must identify the actual statute and asset scope.

A payment deferral can postpone cash collection without eliminating the taxable gain. Security, annual reporting, interest, or acceleration on a later sale may apply. The departure return and any asset inventory must be prepared even when no coins are sold on an exchange.

Country examples that disprove one-size-fits-all advice

Germany: section 6 AStG is about qualifying company shares

Germany's section 6 Foreign Tax Act treats certain events as a fair-market-value disposal of shares within section 17(1) sentence 1 of the Income Tax Act. The official text is not a general deemed-disposal rule for directly held Bitcoin or ordinary payment tokens. Tokenized company shares, business assets, companies, and other structures need their own analysis.

Germany can nevertheless remain relevant if a dwelling or habitual abode continues. Sections 8 and 9 of the Fiscal Code define those connections; merely deregistering or staying abroad for 183 days does not automatically remove an available German home. The actual sale date, private one-year holding rule, business status, and treaty position then matter. See the Germany crypto-tax guide.

Canada: broad deemed disposition on emigration

The Canada Revenue Agency explains that an emigrant is generally deemed to dispose of most property at fair market value immediately before leaving and reacquire it at that value. The CRA lists statutory exclusions and requires the applicable departure forms. Cryptoassets are treated as property for Canadian income-tax purposes, so holdings must be tested against this broad rule and its exclusions rather than assumed exempt.

The CRA identifies Form T1243 for deemed dispositions and Schedule 3 for resulting capital gains or losses. Form T1161 may be required for listed property above the reporting threshold, and Form T1244 can elect to defer payment subject to conditions and possible security. Business inventory and a private capital holding may not produce the same calculation.

United Kingdom: temporary non-residence can bring gains back

Leaving UK residence does not always make an offshore-period disposal disappear. HMRC's current temporary non-residence guidance says specified capital gains arising while temporarily non-resident can become chargeable in the period of return. The Statutory Residence Test, split-year treatment, duration abroad, asset ownership, and return date must be checked before a sale.

This is a clawback framework, not a generic crypto exit tax. A person who remains non-resident and a person who returns after a short absence can have different outcomes from the same exchange sale.

Portugal: loss of residence is now expressly treated as a disposal

Portugal's current Article 10 expressly treats loss of Portuguese tax-resident status as an onerous disposal for the cryptoasset rule. The same article contains the qualifying 365-day exclusion and other conditions, so the result requires a full statutory calculation rather than the slogan "Portugal has no crypto exit tax." This rule is especially important for a person leaving Portugal with appreciated tokens in 2026.

United States: moving does not end citizen taxation

US citizens remain subject to US federal tax on worldwide income while living abroad and generally continue to file US returns. Green-card holders also need to determine when US tax residence legally ends. Renouncing citizenship or ending long-term resident status is a separate, serious process; covered expatriates can fall under section 877A's mark-to-market regime and Form 8854 requirements.

Buying a residence permit in another country therefore does not remove US filing. Foreign tax credits, treaty provisions, information returns, FBAR, and state domicile can remain relevant. The foreign earned income exclusion does not generally convert investment capital gains into excluded earned income.

Does the destination step up crypto cost basis?

Never assume an arrival-date step-up. Some systems create a deemed disposal and reacquisition, some have special rules for assets owned on immigration, and others carry historical acquisition cost and date forward. A departure-country deemed sale does not automatically force the destination to recognize the same fair market value. A mismatch can create double taxation or double non-taxation unless domestic relief or a treaty solves it.

For every asset, maintain three columns until the legal position is confirmed:

1. original acquisition date and original cost including allowable fees,
2. departure-date market value and any gain actually taxed by the old country,
3. destination-country recognized acquisition date and tax basis, with legal authority.

Do not overwrite original ledger data with the chosen destination basis. Store tax adjustments as a separate jurisdiction layer so both country reports remain auditable. If relief depends on foreign tax paid, preserve assessment notices and payment evidence in addition to the calculation.

Separate holdings, income, business and derivatives

A relocation review must classify more than spot disposals. Build separate workpapers for:

• spot tokens: acquisition lots, transfers, swaps, gifts and sales;
• staking and lending: receipt time, control, market value, later basis and validator activity;
• DeFi: deposited and received rights, debt, liquidity positions, rewards and liquidations;
• NFTs: investment, collecting, creator, royalty and business facts;
• derivatives: legal contract, venue, open and close, realized P&L, funding and mark-to-market rules;
• companies: shareholder exit tax, company residence, management, distributions and controlled-company rules.

An open futures position can be unrealized for one system but marked to market by another. A staking reward can be income before the later token sale. A liquidity-token receipt may change beneficial rights even though the user calls it a transfer. These classification questions can matter more than the destination's advertised capital-gains rate.

The cross-border crypto record pack

Export and preserve data before closing accounts or changing exchange country settings:

1. complete exchange trade, ledger, funding, earn, margin, and derivatives files;
2. wallet addresses and transaction hashes establishing continuity of ownership;
3. cost-basis lots and unresolved missing-basis exceptions;
4. fair market values in both countries' required currencies at departure and arrival;
5. exchange-rate source and timestamp convention;
6. old-country final return, departure forms, assessments, and taxes paid;
7. destination opening balance and basis memorandum;
8. residence evidence and treaty analysis;
9. company, employment, validator, protocol, and contract documents.

CoinTaxReporting can maintain transaction-level continuity and produce supported jurisdiction workpapers. It cannot decide a person's treaty residence from wallet data or invent missing legal cost basis. Exceptions should remain visible as "not calculable" or review items rather than silently becoming zero.

A safer relocation timeline

Before the move

Inventory assets and entities, reconcile balances, model unrealized gains, identify possible deemed disposals, obtain valuations, and map both countries' residence tests. Ask for written advice on large planned transactions before executing them.

During the transition

Keep a daily travel and residence log. Avoid assuming a large sale belongs to the new country merely because a visa was issued. Record local execution time, settlement, beneficial owner, exchange entity, and the exact status on that date.

After arrival

Confirm the destination's opening basis, acquisition date, reporting currency, cost method, and treatment of pre-arrival income. File the old country's final and departure forms, then reconcile any foreign tax credits or exemptions. Continue monitoring return visits and retained ties that could revive residence or temporary-non-residence rules.

Worked example: why the answer cannot be guessed

Assume an investor bought 5 BTC for a total cost of €100,000, moves when they are worth €300,000, and sells later for €350,000. Four possible legal patterns illustrate the issue:

The numbers are illustrations, not country conclusions. Fees, exchange rates, holding periods, business classification, losses, relief, and local forms change the result. The 2026 country comparison helps shortlist jurisdictions, while a sample tax report shows the evidence required for calculation.
