Tax residence

Introduction

All users (both physical users and legal entities) going through the KYC verification process must declare at least one country of tax residency. This is an obligation enforced by the CRS and FATCA.

Tip – Not requested for Legal representatives

The legal representative of a legal entity isn’t required to declare a tax residency.

When declaring the tax residence, besides the country, you can also provide:

• The Tax Identification Number (TIN) of the user (optional for all the countries except for US taxpayers).
• The waiver exempting Treezor from liability in case of a missing TIN.

The specific case of US taxpayers

Every US taxpayer must declare the United States as a tax residence along with the Tax Identification Number (TIN).

This applies to all users as soon as one of the following elements value is US:

• Nationality – Corresponds to the nationality or the otherNationality field for the physical users
• Birth country – Corresponds to the birthCountry field for physical users
• Address – Corresponds to the country or secondaryCountry field for both physical users and legal entities

In addition, when at least one of these values is US, the user specificiedUSPerson attribute must be set to 1.

Is considered a US citizen or resident…

A person is presumed to be a citizen of the United States:

• From the moment they have an American passport or
• If they are born on the territory of the United States, even when such a place of birth appears on a passport of another country, or the person also holds another nationality or has their residence in another country.

A person is a resident of the United States if:

• They are holding a green card for permanent residence in the United States.
• They are residing permanently in the United States or have spent a sufficient period of time in the United States over the last three years.
