What Is a Deemed Disposal?
A Deemed Disposal is a tax-law fiction under which assets are treated as sold at market value without a sale, upon events national law defines.
Also known as: Deemed Disposition, Deemed Sale.
How Deemed Disposal works
A Deemed Disposal arises when a statute treats a specified event, such as emigration, a transfer of assets abroad or the passage of time, as a sale at market value, so an unrealised capital gain becomes taxable although no buyer or cash exists. In Canada, an emigrant is deemed to dispose of certain property at fair market value on departure, while Canadian real property and registered pension plans are excluded. Under Article 5 of the EU Anti-Tax Avoidance Directive, companies transferring assets or residence out of a Member State are taxed on market value less tax value. Triggering events, excluded assets, deferral and later step-up rules vary by country.
Deemed Disposal vs Exit Tax
Unlike Exit Tax, which names the charge levied when a taxpayer leaves a jurisdiction, a Deemed Disposal is the underlying legal mechanism, also used for triggers other than departure.
Example
Illustrative example: A software founder holding listed shares emigrates from Canada to Country B. The CRA treats the shares as sold at fair market value on the departure date, so the gain is reported for the year of emigration even though the shares are kept; the founder may elect to defer payment, posting security where the threshold is exceeded.
Common misconception
Myth: No capital gains tax arises on assets which are never sold.
Reality: Where national law provides a Deemed Disposal, such as on emigration from Canada, an unrealised gain can become taxable without any sale.
