What is my Taxpayer Identification Number (TIN)?
Your Taxpayer Identification Number (TIN) is a unique identifier used for tax purposes both locally and globally, issued and provided by your national tax authority.
Depending on where you’re a tax resident, your TIN may be another form of unique identification, called a functional equivalent. For individuals, functional equivalents of a TIN can be checked on the Organisation for Economic Co-operation and Development (OECD) website.
What is tax residency?
Tax residency means the country in which you’re legally obliged to pay taxes. This can be the same country as your physical residency or citizenship, but it may also be in another country, depending on the countries in question.
You may also have tax obligations in more than one country. In these instances, you may have more than one Taxpayer Identification Number (TIN). If you have multiple TINs, please raise a ticket to contact our customer support team.
An overview of the tax residency rules applicable in various countries can be found on the OECD website. If you’re uncertain about your tax residency, you should contact your tax advisor or local tax authority.
