Tax Residency Self-Certification
Brokers & RegulationThe declaration of which countries you are tax resident in, why it is not the same as nationality, and what an unanswered request eventually becomes.
A tax residency self-certification is the declaration a client signs stating which countries they are tax resident in, together with the reference number each of those countries uses to identify a taxpayer. Firms collect it because arrangements between jurisdictions require account information to be reported to the country of residence, and the declaration is what tells the firm where to send it.
Two things about it are commonly misread. It is a statement of tax residence rather than of nationality or of where the account was opened, and the two can differ — residence is decided by the rules of the country concerned, not by the address on a utility bill. And it is a certification, meaning it carries the same weight as any other warranty in the client agreement, with an obligation to notify the firm when it stops being accurate. A firm that cannot obtain a valid certification generally cannot maintain the account normally, which is why an unanswered request eventually becomes a restriction rather than a reminder.
