Key requirements
A Singapore financial institution must identify specified US persons for FATCA and relevant tax residence information for CRS. It may request self-certification, TINs or evidence when opening an account or after indicators such as a foreign correspondence address arise. For entity accounts, controlling-person information may also be needed. Provide accurate information based on the applicable tax rules; a passport or Singapore mailing address alone is not always determinative. Update changes and respond to requests promptly. The two reporting regimes have different coverage, so a person who is not a US person can still be relevant for CRS.
