What is an international estate?

An international succession concerns the transfer of assets after death when the deceased had assets in more than one country, or was resident in a country other than that of his or her nationality.

How are international successions taxed?

Taxation depends on the tax laws of the countries concerned. Some countries tax on the basis of the deceased's place of residence, others on the basis of the location of the assets. Tax rates and rules vary considerably.

What assets are involved in an international estate?

All types of assets can be involved: real estate, bank accounts, investments and personal property. The location and nature of assets influence their tax treatment.

Are there any tax treaties for international successions?

Double taxation can be mitigated by tax credits, deductions, or under tax treaties. It is important to consult an international tax expert to navigate these rules.

What impact do residence and nationality have on international successions?

The residence and nationality of the deceased can influence the jurisdiction competent for taxation. Some countries tax on a worldwide basis, while others focus solely on assets located within their borders.

The deceased's debts are generally deducted from the value of the estate before taxation. However, the rules vary from country to country, and can be complex if the debts are located in different countries.
