There is no universal exit tax triggered whenever an individual changes tax residence. Canada deems many assets disposed when residence ends. Germany applies a deemed sale rule to specified shareholdings in defined circumstances. The United States applies its expatriation regime only to covered expatriates. The United Kingdom generally does not deem an individual's worldwide portfolio sold on departure, although temporary non residence rules can bring specified gains into charge when the individual returns.
The planning task is therefore statutory, not promotional. Each asset must be tested against the origin state's domestic charge, the exact bilateral treaty, available domestic relief, payment rules and reporting obligations.
Four Separate Legal Layers
Cross border planning becomes unsafe when four different systems are treated as one.
- Domestic residence law determines whether and when residence begins or ends under each country's rules.
- Domestic charging law determines whether departure, loss of taxing rights, a transfer, or a later return creates a taxable event.
- Treaty law can allocate taxing rights or provide relief only through the actual treaty in force and the relevant domestic procedures.
- Information reporting can give authorities financial account data without itself creating an exit tax or deciding treaty residence.
An immigration permit does not settle tax residence. A treaty tie breaker does not rewrite domestic charging law. Financial account reporting does not calculate a deemed gain.
OECD Articles 4, 5, 13 and 25
The OECD Model Tax Convention is a model for bilateral agreements. It is not directly binding domestic law.
Article 4 concerns treaty residence. For an individual who is resident under both states' domestic laws, the Model considers permanent home, centre of vital interests, habitual abode, nationality and competent authority agreement in a conditional sequence. The result determines residence for purposes of that treaty. It does not necessarily erase domestic residence or filing duties.
Article 5 defines permanent establishment. Its core concept is a fixed place of business through which an enterprise's business is wholly or partly carried on. Permanent establishment is a business presence question, not an individual Article 4 tie breaker.
Article 13 allocates taxing rights over gains. It does not create a domestic exit tax and does not universally deem emigration to be an alienation. The operative bilateral text, the domestic deemed disposal rule and the timing of the event must be analysed together.
Article 25 provides the mutual agreement procedure. MAP may be available where a person considers that one or both states will tax them contrary to the treaty. A competent authority must endeavour to resolve a justified case that it cannot resolve alone. MAP is not an advance registration, a guaranteed credit, or a promise that the authorities will agree.
Current Domestic Regimes
United Kingdom
The United Kingdom does not impose a general deemed disposal of an individual's worldwide assets merely because the individual ceases UK residence.
Different rules can still apply. Non residents can remain within UK Capital Gains Tax for specified UK land and property interests and assets used by a UK trade. The temporary non residence rules can also treat specified gains realised during a period abroad as arising in the year of return.
HMRC's 2025 to 2026 helpsheet says the temporary non residence conditions generally examine whether the person had sole UK residence for at least four of the seven tax years before departure, had an intervening period without sole UK residence, and returned after a period that did not exceed five years. Split year treatment and the category of gain matter. This is a return based recapture regime, not a general departure tax.
The Foreign Income and Gains regime introduced from 6 April 2025 is a separate residence based relief for eligible new residents. It should not be described as an exit tax rule.
Germany
Section 6 of the German Foreign Tax Act applies a deemed disposal at fair value to shares within section 17(1) of the Income Tax Act when specified events occur. Those events include termination of unlimited tax liability after abandoning residence or habitual abode, a gratuitous transfer to a person who is not fully taxable, and exclusion or restriction of Germany's taxing right over a later sale.
The current statute applies its residence history condition where the individual was fully taxable for at least seven years within the preceding twelve years. Section 6 also contains a return rule for a qualifying temporary absence and permits payment, on application and generally against security, in seven equal annual instalments. Later transfers, distributions, reporting failures and other events can accelerate unpaid amounts.
This is not a tax on every asset. The affected shareholding, residence history, valuation, return conditions and payment obligations must be tested against the current German text.
United States
Sections 877 and 877A concern United States citizens who relinquish citizenship and specified long term residents who end that status. They do not impose a departure charge on every person who stops meeting the substantial presence test.
For expatriations in 2026, an individual can be a covered expatriate if the five year average annual net income tax exceeds USD 211,000, net worth is at least USD 2 million, or the individual does not certify five years of federal tax compliance on Form 8854, subject to statutory exceptions.
Section 877A generally treats a covered expatriate's property as sold at fair market value on the day before expatriation. Special rules apply to deferred compensation, specified tax deferred accounts and interests in nongrantor trusts. Revenue Procedure 2025 32 sets the 2026 gain exclusion at USD 910,000. The exclusion is not a trigger threshold and should not be confused with covered expatriate status.
Canada
When an individual ceases Canadian residence, subsection 128.1(4) can deem specified property disposed and immediately reacquired at fair market value. The Canada Revenue Agency identifies important exclusions, including specified Canadian property, registered plans and other defined rights.
Reporting and payment are separate. Form T1243 reports the deemed disposition. Form T1161 can be required where the fair market value of listed property exceeds the current reporting threshold. An election under subsection 220(4.5), made using Form T1244, can defer payment until a later disposition. Security may be required above the amount stated in current CRA guidance.
Canada therefore illustrates why a headline departure tax is incomplete without the asset exclusions, forms, election deadline and security rules.
Comparison Table
| Jurisdiction | Relevant event | Broad scope | Important qualification |
|---|---|---|---|
| United Kingdom | Return after qualifying temporary non residence, plus separate non resident charges | Specified gains and income | No general worldwide deemed sale merely on departure |
| Germany | Events listed in section 6 of the Foreign Tax Act | Specified shares within section 17 of the Income Tax Act | Residence history, return rule, instalments and acceleration events matter |
| United States | Expatriation by a covered expatriate | General mark to market rule plus special asset categories | Covered status and the gain exclusion are separate tests |
| Canada | Cessation of Canadian residence | Deemed sale of many property classes | Statutory exclusions, reporting and elective payment deferral apply |
Treaties, Credits and the MLI
A treaty should not be described as automatically neutralising an exit tax. The analysis requires the exact bilateral provisions corresponding to Articles 4, 13, 23 and 25, together with domestic credit and payment rules.
The Multilateral Convention to Implement Tax Treaty Related Measures to Prevent BEPS, known as the MLI, is a separate instrument. It modifies only Covered Tax Agreements. Both parties must list the bilateral agreement, and the result depends on ratification, effective dates, matching notifications, reservations, optional provisions and compatibility clauses.
The MLI does not supplement the Common Reporting Standard and does not standardise deemed disposal reporting. Its Article 7 principal purpose test can deny a treaty benefit where it is reasonable to conclude, having regard to all relevant facts and circumstances, that obtaining that benefit was one of the principal purposes of an arrangement or transaction, unless granting the benefit accords with the object and purpose of the relevant provisions. The actual treaty position must be reconstructed from both parties' MLI positions.
CRS, FATCA and Financial Account Information
The Common Reporting Standard provides for the automatic exchange of financial account information. It requires Reporting Financial Institutions to identify Reportable Accounts and report specified information for annual exchange under implementing domestic law and activated exchange relationships. Reported fields can include identifying details, tax residence, account balance or value, interest, dividends and gross proceeds.
The CRS does not determine residence, impose an exit tax, calculate a gain, or standardise a departure tax return. The 2025 consolidated text reflects expanded coverage for specified electronic money, central bank digital currencies and certain indirect crypto asset exposures. Domestic implementation and effective dates still vary.
FATCA is a separate United States regime. The Crypto Asset Reporting Framework is also separate and concerns reportable crypto asset transactions. None should be treated as a component of the BEPS MLI.
A Defensible Planning Sequence
1. Establish residence dates
Apply each country's domestic residence law and any split year or part year rules. Do not infer tax residence from immigration status or a 183 day slogan.
2. Inventory assets and legal interests
Identify direct holdings, options, deferred compensation, trusts, companies, partnerships, pensions, real property, debt and digital assets. Different statutory categories can produce different departure treatment.
3. Reconstruct basis and fair value
A deemed disposal requires supportable acquisition cost and valuation evidence. Private company shares, carried interests and restricted securities require particular care.
4. Model payment and liquidity separately
Tax liability, filing, security and payment dates are not the same question. An instalment or deferral election can carry conditions that accelerate payment later.
5. Read the actual treaty
Confirm treaty residence, gains allocation, relief from double taxation and MAP wording. Then determine whether the treaty is a Covered Tax Agreement modified by the MLI.
6. Map reporting
Identify domestic departure forms, beneficial ownership filings, CRS or FATCA self certifications and later change in circumstances duties. Reporting does not determine the substantive tax result, but errors can create separate penalties.
Frequently Asked Questions
Does every country impose an exit tax when residence ends?
No. The trigger, taxpayer, asset scope and timing differ. Canada has a broad deemed disposition with exclusions. Germany section 6 targets specified shares and events. United States section 877A applies to covered expatriates. The UK temporary non residence rules operate on a later return rather than imposing a general worldwide deemed sale on departure.
Did the UK introduce an exit tax in April 2025?
No general individual exit tax was created by the FIG reform. The change replaced the remittance basis with a residence based regime for foreign income and gains. Temporary non residence and non resident gains rules remain separate.
Can a treaty eliminate departure tax?
Not as a general rule. Domestic charging law, the actual treaty, credit provisions and payment rules must be considered together. MAP is a dispute procedure, not guaranteed relief.
Does CRS report unrealised exit tax gains?
CRS reports specified financial account information. An account balance or value is not a universal tax basis or deemed gain field, and CRS does not calculate exit tax.
What should be completed before relocation?
Residence analysis, asset classification, basis and valuation records, liquidity modelling, treaty review and reporting calendars should be completed before a taxable event where possible. The exact work depends on the jurisdictions and assets involved.
